From 091def8b685bd48e007cca5a5ef3b93d911f4adb Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 17 Sep 2026 18:30:42 +0000 Subject: [PATCH 001/148] docs(quartz): plan Cordn interop via a binding-agnostic MLS core Cordn (cordn.net) is an alternative binding of RFC 9420 onto Nostr, not an alternative to MLS. It agrees with Marmot on the crypto layer -- ciphersuite 0x0001, a byte-identical ChaCha20-Poly1305 outer seal over an MLS-exporter key, the pre-commit epoch rule for Commits, and the unsigned NIP-01 application envelope with kind 9 chat -- and diverges completely above it: the delivery service is an MCP server reached over ContextVM (kind 25910), with per-group monotonic cursors, history in the coordinator's SQLite, and no key-package event kind at all. So the only shareable code is the RFC 9420 engine, which currently lives inside quartz/.../marmot/mls/ and is not yet binding-agnostic: 3 files with 10 imports into the Marmot layer, plus 3 hardcoded Marmot policies (required_capabilities 0xF2EE, the "marmot"/"group-event" exporter label, leaf capabilities). Extracting it is the prerequisite and stands on its own merits. Records the verified divergences with file:line citations -- the blocking one being credential identity encoding (we require raw 32 bytes, cordn requires 64 bytes of hex ASCII) -- a coordinator metadata-exposure analysis, the LGPL-3.0 status of the ContextVM SDK (clean-room only), and a staged plan gated on the upstream encoding decision. Research only; no implementation. The MLS interop tests could not be executed in this environment (Maven Central 429), so Stage 0 restores executable verification before anything else.

Both are bindings of RFC 9420 +onto Nostr; they agree almost exactly on the crypto layer and disagree on everything above it. + +- **Same:** ciphersuite `0x0001`, the ChaCha20-Poly1305 outer seal (byte-identical framing), the + MLS-exporter-derived seal key, the pre-commit epoch rule for Commits, and the unsigned + NIP-01-shaped application envelope with `kind: 9` chat. +- **Different:** the delivery service. Marmot publishes kinds 443/444/445 to relays. Cordn calls + an **MCP server over ContextVM** — 11 tools, per-group monotonic cursors, history in the + coordinator's SQLite, and *no key-package event kind at all*. + +So the only code both bindings can share is the RFC 9420 engine. Everything named `Marmot*`, +`Mip*` or `mip0*` is the wrong layer and must not be reused. + +The engine is reusable but **not yet binding-agnostic**: it lives inside +`quartz/…/marmot/mls/`, and three files plus three hardcoded policies leak Marmot into it (§5.1). +Extracting it is the prerequisite for this work and is worth doing on its own merits. + +Recommended sequencing: **Stage 0 (vectors) → Stage 1 (extract engine) → decide → Stage 2+.** +Do not start Stage 2 before the §4.1 decision, because if it goes the wrong way every KeyPackage +is permanently ecosystem-bound and "interop" degrades to Amethyst speaking two unrelated +protocols. + +## 2. The coordinator protocol surface + +Eleven MCP tools (`cordn/packages/core/src/contracts.ts`): + +``` +kp_publish kp_list kp_take kp_remove +welcome_store welcome_take +join_request_store join_request_take_many +msg_post msg_fetch_many msg_sub_many +``` + +Transport is ContextVM: kind **25910** ephemeral events whose `content` is a stringified MCP +JSON-RPC message, `p` = peer, `e` = request correlation, optionally gift-wrapped in 1059/21059 +(`contextvm-sdk/src/core/constants.ts`). `msg_sub_many` needs **CEP-41** open streams and the +coordinator also enables **CEP-22** oversized transfer, both framed over +`notifications/progress`. + +Delivery model (`cordn/spec/00.md`, `spec/03.md`): the coordinator stores opaque bytes keyed by an +outer delivery id `gid`, assigns a monotonic per-group cursor, and must not parse payloads. It +cannot distinguish a Commit from a chat message — epoch, wireformat and content-type were +deliberately removed from its view (`cordn/design/private-coordinator-refactor.md`, which is an +explicit study of Marmot's kind-445 and the reason the two seals match). + +`gid` is spec'd as decoupled from the MLS `group_id`, but the reference client sets both to +`utf8(crypto.randomUUID())` (`cordn-web/src/lib/services/chatGroupLifecycle.svelte.ts:76`, +and `getProtocolGroupId` at `:83` reads the `gid` straight back out of the group context). + +Group sharing is a bech32 `cordn1…` string with NIP-19-shaped TLV (type 0 = `gid` as UTF-8, +1 = coordinator pubkey as raw 32 bytes, 2 = relay URL), bech32 not bech32m +(`cordn/spec/applications/group-ref.md`).

The RFC 9420 core is therefore a known quantity, subject to the +caveat in the header that this container could not re-run it. + +Note what this table is *not*: none of these are reuse candidates. `GroupEventEncryption`, +`MarmotAppEvent` and MIP-04 media are Marmot-layer code. The table says a cordn-side +implementation will look structurally familiar and can be written with confidence — it will be +parallel code under `quartz/…/cordn/`, not a shared path. + +## 4. Verified divergences + +### 4.1 Credential identity encoding — hard incompatibility, decide first + +- Ours: raw **32 bytes**, x-only pubkey. `KeyPackageUtils.kt:253` — + `if (credential.identity.size != 32) return false`. +- Theirs: **64 ASCII bytes** of lowercase hex. `chatMlsUtils.ts:251` — + `identity: new TextEncoder().encode(stablePubkey)`; the coordinator reads it back with + `TextDecoder` and string-compares to `event.pubkey` + (`coordinatorMethods.ts:118-151`). + +One KeyPackage cannot satisfy both. This is exactly what `spec/00.md` §13 requires +implementations to agree on, and the two ecosystems picked differently. It is a one-line change +on either side today and unfixable once either has deployed users at scale. + +**Action:** raise with gzuuus before Stage 2. Either side moving is fine; what matters is that +one does. + +### 4.2 No key-package event kind + +There is no cordn equivalent of Marmot's kind 443. `kp_publish` takes `{ kp_ref, kp_64 }` — plain +base64 in the JSON-RPC arguments. The "signed publication payload" of `spec/00.md` §7 is the +**ContextVM request event itself**: the coordinator reaches back into the transport for it +(`coordinatorServer.ts:92` → `transport.getNostrRequestEvent(requestEventId)`), stores it +verbatim, and returns it on `kp_take`. A consumer then does +(`chatMlsUtils.ts:579-613`): + +```ts +if (!verifyEvent(publicationEvent)) throw … +const kp64 = JSON.parse(publicationEvent.content).params?.arguments?.kp_64 + ?? JSON.parse(publicationEvent.content).params?.arguments?.keyPackageBase64; +``` + +i.e. the KeyPackage is recovered by parsing JSON-RPC out of a kind-25910 event's `content`, and +identity binding is `decodeKeyPackageIdentity(kp) === publicationEvent.pubkey`. + +Consequences: + +- A Marmot kind-443 event cannot serve as a cordn publication payload or vice versa. There is no + "publish to relays, interop on KeyPackages only" shortcut — KeyPackage publication is + inseparable from having a working ContextVM client. +- The invariant rides JSON-RPC envelope shape rather than a stable event schema, and the client + already carries a fallback from an earlier field rename (the `?? keyPackageBase64` above). + +**Worth proposing upstream** alongside §4.1: give KeyPackage publication its own signed payload +(or its own kind). That is mutual-benefit — it would let a cordn KeyPackage be published to relays +and consumed without a coordinator at all. + +### 4.3 Last-resort marker + +Ours: MLS extension `0x000A`. Theirs: mls-extensions `app_data_dictionary` (`0x0006`) with +component id `0x0004` and empty component data +(`cordn/packages/core/src/lastResortKeyPackage.ts`). We already have `AppDataDictionary.kt`, +`ComponentsList.kt` and `AppDataDictionaryInteropTest` — this is a codec selection, not new work. + +### 4.4 Capability gates keep the two group types disjoint + +Marmot groups carry `required_capabilities = { extensions: [0xF2EE], proposals: [0x000A +self_remove] }` (`MlsGroup.kt:3255`, built by `buildMarmotRequiredCapabilitiesExtension()` at +`:3259`). Cordn groups use GroupContext extension `0xC04D cordn_group_metadata` and require +members to advertise it (`spec/01.md` §7). Neither client can be *added* to the other's groups. +Cheap to fix by advertising both in `Capabilities`, but "one group, both clients" is a deliberate +profile decision, not a free consequence of sharing an engine. + +### 4.5 Encrypted media diverges + +Exporter *context* matches (`"encrypted-media"`), but cordn uses the exporter output directly as +the file key with `aad = mime‖0x00‖filename‖0x00‖sha256(plaintext)`, where our MIP-04 v2 does +`HKDF-Expand(exporter, context)` with `aad = "mip04-v2"‖0x00‖hash‖0x00‖mime‖0x00‖filename`. +Separate codec; shared primitives (ChaCha20-Poly1305, NIP-92 `imeta`, Blossom) all already exist. + +### 4.6 Multi-device is not interoperable — explicit non-goal + +`spec/applications/multi-device.md` ships `base64(serialized ts-mls ClientState)` inside sealed +Blossom documents advertised by an opaque tip. That is a ts-mls-internal serialization, not an MLS +wire format. There is nothing to implement against. Do not attempt it. + +## 5. What we already have + +### 5.1 The engine, and how Marmot-clean it is + +`quartz/…/marmot/mls/` is **11,964 LOC**. Measured coupling to the Marmot layer: + +- **3 files**, **10 imports** total: + - `group/MlsGroup.kt` (7): `MarmotGroupData`, `MarmotGroupState`, `AdminPolicyV1`, + `AppComponentIds`, `AgentTextStreamCrypto`, `AgentTextStreamQuicPolicyV1`, + `AgentTextStreamRoles` + - `group/MlsGroupManager.kt` (2): `AdminPolicyV1`, `GroupLifecycleV1` + - `messages/MlsKeyPackage.kt` (1): `AppComponentIds` +- **Zero** Marmot imports in `codec/`, `crypto/`, `tree/`, `schedule/`, `framing/`, + `components/`, `messages/{Commit,Proposal,Welcome}`. + +Plus three Marmot policies hardcoded *inside* the engine that a cordn group must not inherit: + +| Location | Hardcoded | +| -------- | --------- | +| `MlsGroup.kt:3259` | `required_capabilities = {ext:[0xF2EE], props:[0x000A]}` | +| `MlsGroup.kt:650`, `:4276` | `exporterSecret("marmot", "group-event", 32)` — label baked in | +| `KeyPackageRotationManager.kt:645-670` | leaf `capabilities.extensions = [0x000A, 0xF2EE]` | + +`MlsGroup.kt:2072` already exposes `exporterSecret(label, context, length)`, so the last of those +is a call-site fix, not a redesign. + +### 5.2 Reusable as-is + +NIP-44 (and NIP-59) for the ContextVM gift wrap, NIP-19 bech32/TLV for `cordn1…`, +`ChaCha20Poly1305`, the TLS presentation-language codec (`mls/codec/`) for the `0xC04D` extension, +Blossom (`nipB7Blossom`), `INostrClient` and the `accessories/` one-shot helpers for relay I/O, +and `NostrSigner` for both identities. + +## 6. Licensing + +🔴 **`ContextVM/sdk` is LGPL-3.0** (`COPYING.LESSER` over the GPL-3 base text; `package.json` +declares `LGPL-3.0-1`). We would not link a TypeScript library into Quartz regardless, but per the +dependency rule in `.claude/CLAUDE.md` this means: + +- A Kotlin ContextVM implementation **must be clean-room from the spec and CEP documents**, not a + translation of that source. A derivative translation would carry LGPL terms into MIT Quartz. +- `cordn-rs` links the Rust `contextvm-sdk` as a dependency; that is their artifact, not ours. +- If a Kotlin/JVM ContextVM library ever appears under LGPL, linking it is a WARN-and-call-out + (call it out in the PR description), not an automatic stop. + +Everything under `Cordn-msg` is MIT, so the specs and the reference coordinator are safe to read +and to implement against. + +## 7. What the coordinator can see + +Content: **nothing.** Double-sealed (MLS ciphertext, then ChaCha20-Poly1305 under the epoch +exporter), and the coordinator is forbidden from parsing. It cannot even tell handshake from +application traffic. This is genuinely stronger than a conventional MLS delivery service. + +Metadata is where the cost sits. Every call carries an authenticated caller pubkey +(`extra._meta.clientPubkey`, derived from the signed inner 25910 event), and cordn-web splits +identities deliberately: + +| identity | calls | +| -------- | ----- | +| **stable** (real npub) | `kp_publish`, `kp_remove`, `welcome_take`, `join_request_store` | +| **ephemeral** | `kp_take`, `kp_list`, `welcome_store`, `join_request_take_many`, `msg_post`, `msg_fetch_many`, `msg_sub_many` | + +### 7.1 Admission is in the clear on both ends + +`join_request_store` carries the **stable** identity and the `gid` → "npub X wants into group G". +`welcome_store` names the **target's stable pubkey**; `welcome_take` is called by that target's +**stable** identity. For any group joined via a share link the coordinator observes real-identity +membership directly. Structural, not a bug. + +### 7.2 The ephemeral identity is per-session, not per-message + +`coordinatorClient.ts:169` → `new PrivateKeySigner()` with no argument, constructed once per +`cordnClient`, and `chatRuntime.ts:62` caches one client per coordinator pubkey. So **one +pseudonym posts, fetches and subscribes across every group you have on that coordinator, for the +whole session.** That `gid` set is a stable fingerprint: it links all your groups together and +leaks how many you are in. Marmot rotates per kind-445 event and has no equivalent linkage +(relays still see `h` tags and fetch patterns — different exposure, not obviously better). + +### 7.3 Complete ordered history in one place + +Per-group cursors, `at` timestamps, sealed payload sizes (no padding specified anywhere I could +find), per-`gid` rates, live subscription membership. Cross-`gid` timing correlation inside one +session is trivial. Unlike relays there is no redundancy or partitioning: one operator sees the +whole graph of every group it serves, retained in SQLite. + +### 7.4 A signed, verifiable record that you use cordn + +`kp_publish` rides the stable identity and the coordinator retains the signed event — it is +*designed* to be re-servable as proof, rotation cadence included. `kp_take`/`kp_list` also reveal +who is being looked up, i.e. "someone is about to add X to a group". + +### 7.5 IPs go to relays, not the coordinator + +A real structural win over an HTTP delivery service. The relay then sees the 21059 traffic pattern +and the `p` tag naming the coordinator: who talks to which coordinator, how often, how big. + +### 7.6 Encryption can silently downgrade — pin it + +cordn-web pins `giftWrapMode: GiftWrapMode.EPHEMERAL` (`coordinatorClient.ts:186`) but leaves +`encryptionMode` at the SDK default **`OPTIONAL`** +(`contextvm-sdk/src/transport/base-nostr-transport.ts:102`), which resolves as +`isEncrypted ?? true` from negotiated session state (`:544`). The reference coordinator does +announce `support_encryption`, so live deployments are encrypted — but the policy permits a +coordinator that does not announce it to receive **plaintext JSON-RPC on public relays**, +exposing `gid`, `target_pk`, `kp_64` and cursors to any relay. + +**Our client must pin `REQUIRED` and fail closed.** Non-negotiable. + +### 7.7 Net + +Content privacy equals Marmot's. Metadata privacy is **weaker than Marmot's against the delivery +operator** and **stronger against the network**. Whether that trade is acceptable depends on +whether coordinators are self-hosted per community or a handful of public ones; the spec permits +either, and the shipped default is one coordinator pubkey over three public relays +(`cordn/README.md`). + +This section should be surfaced in the UI if we ship this, not buried. A Marmot group and a cordn +group have materially different metadata exposure and users cannot infer that from either one +looking like a group chat. + +## 8. Plan + +### Stage 0 — Ground truth and the upstream conversation + +No production code. Two deliverables. + +1. **Restore executable verification.** Get `:quartz:jvmTest` green in a clean container + (the 429 in the header) and confirm `TsMlsWelcomeInteropTest`, `MdkWelcomeInteropTest` and + `AppDataDictionaryInteropTest` still pass. Everything downstream assumes the engine is sound. +2. **cordn-side vectors.** `@cordn/cli` is published and has a filesystem-queue mode built for + scripting; the coordinator ships as `ghcr.io/cordn-msg/cordn:latest` with + `CORDN_STORAGE_BACKEND=memory`. Drive both to emit a vector file (KeyPackage with hex-ASCII + credential, Welcome, a sealed application payload, a sealed Commit, a `cordn1…` group ref, a + `0xC04D` extension blob) into `quartz/src/commonTest/resources/cordn/`, with a generator under + `quartz/tools/cordn-vector-gen/` mirroring `tools/tsmls-vector-gen/`. Assert them in + `quartz/…/cordn/interop/`. + + These tests will fail on the credential encoding, by design — that is the point. They convert + §4.1 from an argument into a reproducible artifact we can hand upstream. +3. **Raise §4.1 and §4.2 with gzuuus.** Credential encoding is the blocking one. The + key-package-payload shape is the higher-value ask. + +**Gate:** do not start Stage 2 until §4.1 has an answer. Stage 1 is safe to do regardless. + +### Stage 1 — Extract a binding-agnostic RFC 9420 engine + +Worth doing whether or not cordn ever ships. Today the engine is one protocol's private detail; +this makes it a library. + +- Move `quartz/…/marmot/mls/` → `quartz/…/mls/`. Packages change; `marmot/` keeps everything + else. +- Parameterize what §5.1 lists as hardcoded: group id, credential identity bytes, + `required_capabilities`, leaf `capabilities`, and the exporter label/context all become + constructor or call-site inputs. `exporterSecret(label, context, length)` already exists — + stop calling it with a literal `"marmot"` from inside the engine. +- Push the Marmot-specific reads out to `marmot/`: `currentMarmotData()`, `currentGroupState()`, + `currentNostrGroupId()`, the `AdminPolicyV1`/`GroupLifecycleV1` hooks and the agent-text-stream + helpers. Where the engine needs a policy decision, it takes an interface; `marmot/` supplies the + Marmot implementation. +- Move `group/MarmotMessageStore.kt` out (it is named for Marmot and keyed on + `nostrGroupId` — it is a binding concern). +- Behaviour must not change. The existing MLS + Marmot test suites are the contract; they pass + unmodified except for import lines. + +Risk: `MlsGroup.kt` is 4,505 lines and carries the convergence/lifecycle logic. Keep this stage +strictly mechanical — extraction and parameterization, no logic edits — so the diff stays +reviewable and the test suite is a real check. + +### Stage 2 — `:contextvm` module (clean-room) + +New Gradle module, peer of `:quic`. Depends on `:quartz` only; no Android framework deps. Written +from `docs.contextvm.org` + the CEPs, **not** from the LGPL SDK (§6). + +- kind 25910 request/response with `p` addressing and `e` correlation +- NIP-44 gift wrap to 1059/21059 — note their scheme is a *simplified* NIP-59 (direct NIP-44 to a + wrapper event, no inner seal/rumor), and the server verifies the decrypted inner event's + signature +- `encryptionMode = REQUIRED`, fail closed (§7.6) +- server discovery: addressable 11316–11320 + NIP-65 10002, with the `support_encryption`, + `support_encryption_ephemeral`, `support_oversized_transfer`, `support_open_stream` tags +- CEP-22 oversized payload and CEP-41 open streams over `notifications/progress` +- a minimal MCP client: `initialize` → response → `notifications/initialized`, then `tools/call` +- dual-signer support: an account `NostrSigner` for the stable identity and a locally generated + key for the ephemeral one + +Sizing reference: the SDK's client-side surface (`src/core` + `src/transport/nostr-client` + +oversized-transfer + open-stream, tests excluded) is ~5.4k lines of TypeScript. Reusable beyond +cordn — any MCP-over-Nostr work lands here. + +Signer note: the stable transport needs `sign()` *and* NIP-44 encrypt/decrypt per MCP message. On +a NIP-55/NIP-46 external signer that is a round-trip per request. cordn-web's stable/ephemeral +split already keeps stable traffic rare; preserve that property rather than fighting it. + +### Stage 3 — `quartz/…/cordn/` binding + +- The 11-tool coordinator client over `:contextvm`, with the stable/ephemeral split of §7 encoded + in the API so a caller cannot accidentally leak the stable identity onto the message path. +- `cordn1…` group ref codec on the existing NIP-19 bech32/TLV primitives. +- `CordnGroupMetadata` (`0xC04D`) TLS codec on `mls/codec/`. +- cordn's `app_data_dictionary` last-resort variant (§4.3). +- A cordn-profile KeyPackage builder: hex-ASCII credential identity, cordn capabilities, no + `0xF2EE`, no Marmot required-capabilities. +- The seal: ChaCha20-Poly1305 over `MLS-Exporter("cordn","group-payload",32)`, pre-commit epoch + for Commits. Same algorithm as `GroupEventEncryption`, separate call site — do not import the + Marmot one. +- The application envelope: same shape as `MarmotAppEvent`, separate type in `cordn/`. +- Per-group cursor tracking, fetch-then-subscribe (bounded `msg_fetch_many` catch-up, then + `msg_sub_many` from the freshest cursor), self-echo reconciliation by envelope `id`, and + pending-epoch-operation finalization only on observing the matching inbound Commit. The + reference client's `packages/cli/README.md` documents these rules and they are not optional — + getting them wrong desynchronizes MLS state. + +### Stage 4 — App integration + +- `commons/` state holders and ViewModels for cordn groups, alongside the Marmot ones. +- Coordinator configuration and health surface (their client tracks per-coordinator health). +- **Surface the metadata model (§7) in the UI.** A cordn group and a Marmot group are not + equivalent privacy-wise and must not look identical. +- `amy` verbs for scripted interop testing, per the thin-assembly-layer rule. + +### Non-goals + +- Multi-device (§4.6) — nothing interoperable to build. +- Reusing any `Marmot*`/`Mip*` type for cordn. +- A Kotlin ContextVM *server* — `cordn-rs` exists, is faster, and shares the SQLite schema. If we + ever want a coordinator, run theirs. +- Bridging a Marmot group and a cordn group into one MLS group. Possible in principle once §4.1 + and §4.4 are resolved, but it is a separate design with its own trust questions. + +## 9. Open questions + +1. **§4.1 credential encoding** — who moves? Blocks Stage 2. +2. **§4.2 publication payload** — will upstream give KeyPackage publication its own signed payload + or kind? Changes whether cordn KeyPackages can exist outside a coordinator. +3. **Is the goal interop or a second transport?** "Amethyst can talk to cordn users" and "Amethyst + supports coordinator-backed groups" are different products.

Reviewed the specification and all 12 CEPs and scoped the work: 7 are load-bearing for cordn (the core spec, CEP-4/19 encryption, CEP-6/17 discovery, CEP-35 stateless discovery, and CEP-22 bounded oversized transfer plus CEP-41 open streams), CEP-16 is server-side but load-bearing for the KeyPackage identity binding, and CEP-8 payments plus CEP-15 common tool schemas are confirmed unused by cordn. Only 3 of the 7 are Final; both big ones are Draft, which is the main schedule risk. Records the fourteen rules where a naive implementation passes unit tests and then diverges against the live coordinator -- CEP-41's two independent ordering fields, per-sender progress sequences, close not satisfying the JSON-RPC lifecycle, the digest being over the exact serialized string, conditional accept, mandatory keepalive, and the fact that kind 25910 is ephemeral so there is no replay and subscriptions must precede publication. Adds an ordered build list with substages, a conformance strategy (rule-derived negative tests plus live integration against the reference coordinator image), and four new open questions. Sourcing: the review is derived from ContextVM/contextvm-docs, not the LGPL-3.0 SDK, so Stage 2 can be implemented clean-room. That repo carries no LICENSE file, so the plan says implement the protocol and paraphrase rather than pasting spec prose.

Each is a spec MUST and should become a test. + +1. **CEP-41 has two ordering fields, and they are not interchangeable.** `progress` orders *all* + frames (control frames included) and is explicitly **not** a chunk counter. `chunkIndex` starts + at `0`, increases contiguously by `1`, and is what receivers MUST use to validate contiguity + and completeness. Conflating them is the obvious first bug. +2. **Progress sequences are per-sender**, each starting at `1`. A frame's `progress` may only be + compared against frames from the same peer. A `pong`'s `progress` comes from the responder's own + sequence and has **no** required ordering relationship to the triggering `ping`; pongs match by + `nonce` only. Do not build one shared counter per stream. +3. **`close` does not complete the JSON-RPC request.** After `close` the sender MUST still send the + final JSON-RPC success response, and a client MUST NOT synthesize success from `close` alone. + So `msg_sub_many` has two independent completion signals — cordn-web's API shape + (`{ stream, result, abort }`) is a direct consequence, not a style choice. +4. **The CEP-22 digest is over the exact serialized string**, UTF-8-encoded — not over a + re-serialized JSON object. Any reparse-and-reserialize (key reordering, whitespace) breaks it. + The reassembly path must carry bytes end to end and only parse after the digest verifies. +5. **`accept` is conditional bootstrap, not a handshake.** Skip it when peer support is already + known; it is **mandatory before the first `chunk` in stateless flows**. cordn is stateless, so + our client→server oversized path must wait for `accept`. +6. **CEP-41 keepalive is mandatory.** Any valid frame resets the idle timer; on expiry the peer + MUST send `ping`; no matching `pong` before the probe timeout MUST fail the stream. cordn-web + runs 30s/30s explicitly because the SDK's 20s default turned a single lost relay round-trip into + a stream abort. Do not ship a 20s window. +7. **Relay size limits apply to the whole serialized event**, ~64 KiB in practice, not just + `content`. Chunk sizing must budget for base64 expansion plus JSON plus event overhead, with + conservative margin, and MUST NOT assume a uniform threshold across relays. +8. **Encryption leaks the recipient.** CEP-4 says so outright: the gift wrap carries a `p` tag for + the recipient. Sender, inner kind and real timestamp are hidden; the recipient pubkey is not. +9. **Gift wrap timestamps are randomized** per NIP-59 — never use them for ordering. +10. **The inner event is fully signed, not a rumor.** CEP-4's flow signs the 25910 event *first*, + then NIP-44-encrypts the whole thing into the wrap. Receivers verify the inner signature, and + response correlation uses the **inner** `id`, not the gift wrap's. +11. **Three separate correlation identifiers coexist**: the nostr `e` tag (event level), the + JSON-RPC `id` (MCP level), and `progressToken` (CEP-22/41 transfer level). Plus + `_meta.clientPubkey` (CEP-16) as the coordinator's authenticated caller identity — which is the + mechanism §4.2's KeyPackage binding ultimately rests on. +12. **Ephemeral delivery has no replay.** Per §6.1, subscribe before you publish. Combined with + per-identity subscriptions (§8.2), each identity needs its own live `#p` subscription on 25910 + plus both gift wrap kinds. +13. **A zero-chunk stream is valid** — `close` immediately after `start`, with `lastChunkIndex` + omitted. An empty `msg_sub_many` backlog will exercise this on day one. +14. **`close.lastChunkIndex` is optional and meaningful.** Present, it is a completeness bound and + every index `0..lastChunkIndex` must have arrived; omitted, the stream was open-ended and no + bound is asserted. Senders omit it for live feeds. + +### 6.4 Build list for `:contextvm` + +Ordered so each item is testable before the next depends on it: + +| # | Component | Notes | +| - | --------- | ----- | +| 1 | Kinds, tags, frame types, JSON-RPC 2.0 codec | Pure data; port the constant set from the spec | +| 2 | Minimal MCP client | `initialize`, `notifications/initialized`, `tools/call`, typed errors, `_meta`/`progressToken` plumbing.

Adds a 13-row matrix (core spec + 12 CEPs) with status, surface, a CVM-* rule id prefix per document, and the test tier each must clear. Rule ids follow the STORE-Fxx convention from the event-store-semantics skill so a future divergence can be named rather than described. Defines five test tiers, because the CEPs are symmetric and no single counterparty exercises them all: rule-derived unit tests, live integration against the reference coordinator, adversarial tests against our own fixture server, cross-implementation vector exchange, and wallet integration for CEP-8. Tier C is the one that does not exist yet and is now a first-class deliverable: no real server sends a non-monotonic progress, a stale pong nonce or a mismatched digest, yet all three are MUST-fail requirements. Also records a per-CEP test catalog with the negative cases called out explicitly, and two findings from reading CEP-8 and CEP-15 in full: both require RFC 8785 JSON canonicalization, which Quartz does not have (the canonicalize hits in the tree are IPv6, media types and relay URLs), and CEP-8 forbids silent fallback in both directions -- a payment handler that pays whatever it is asked violates the client half. Build list grows to 16 items, Stage 2 splits into 2a-2f gated on rule-id groups, and three open questions are added on the fixture server, CEP-8's real priority, and upstream conformance vectors.

Written from the ContextVM specification documents, not from the LGPL-3.0 SDK, per the plan's clean-room rule. - :contextvm is a KMP module (jvm + android host tests) mirroring :quic, with quartz as an api dependency. It takes its own kotlinx-serialization-json because quartz keeps that dependency `implementation`. - CvmKinds/CvmTags carry the wire vocabulary: kind 25910, gift wraps 1059 and 21059, announcements 11316-11320, NIP-65 10002, and the capability, discovery, pricing and NIP-73 tag names from the CEPs. - JsonRpcCodec models JSON-RPC 2.0 with params/result left as a JSON tree, since ContextVM transports MCP unmodified. Ids keep their string-vs-number distinction instead of normalising, so decode/encode is a faithful round trip and CEP-8's canonical-identity rule stays expressible later. - Decoding is strict: wrong version, result and error together, a method beside a response body, a success without an id, non-object params and a fractional id are all rejected rather than coerced. - CvmMessageEvent maps the envelope, keeping content a stringified JSON-RPC message (the spec prints it unstringified for readability, which is the trap) and excluding routing tags from the CEP-35 discovery surface while preserving unknown ones. 29 tests, named for the CVM-CORE rule ids in the plan's §6.5 catalog so a spec revision points at the failures. Verified by mutation: disabling the version check and normalising ids to text turns 10 of them red. :quartz jvmTest stays green at 5054 tests.

Frame codec, bounded-reassembly receiver and the fragmenting sender, over the notifications/progress envelope both transfer profiles share. Two wire details the spec only shows by example, and both are digest-critical: chunk `data` is a raw substring of the serialized JSON-RPC message rather than base64, and `digest` is algorithm-prefixed (`sha256:`). Fragments are therefore concatenated as text and encoded to UTF-8 once; the payload is never parsed and re-serialized in transit, which would reorder keys and break the hash. Receiver enforcement: admission control on declared totalBytes/totalChunks before any state is committed, chunk/end position validated against start, duplicate progress rejected, bounded out-of-order buffering, and nothing surfaced upward until the chunk count, byte length and digest all agree. Sender never splits a surrogate pair, since both halves would survive JSON encoding individually but rejoin into a different codepoint. One design bug caught by its own test: the receiver initially rejected frames whose progress did not increase on arrival, conflating "the sender emits monotonic progress" with "frames arrive in order". CEP-22 says the opposite -- progress is the assembly index and explicitly not a guarantee of arrival order, and receivers may buffer out-of-order chunks. The check is now positional (chunks sort after start, end after every chunk) rather than arrival-ordered. 21 CVM-22-* tests, 14 of them negative. Module suite at 50.

feat(contextvm): CEP-41 open-ended streams Build item 9. All seven frame types, the receiver state machine, and keepalive with an injectable clock. The profile carries two independent ordering fields and the whole design turns on keeping them apart: `progress` orders every frame including control frames and is explicitly not a chunk counter, while `chunkIndex` -- contiguous from 0 -- is what validates payload completeness. Chunks are buffered by chunkIndex and released as the contiguous run extends, so a gap is a provisional state while the stream is live rather than an error. Progress sequences are per-sender, so a pong's progress has no required relationship to the ping it answers; pongs match by nonce alone. A pong for a nonce we never sent is ignored rather than fatal -- failing would let a third party disrupt a stream by replaying a stale pong -- but it is not counted as liveness either, so the real probe still expires. Other enforced rules: a second start on a live token fails, close is required for success, lastChunkIndex is a completeness bound that must be satisfied and must be omitted when no chunks were sent, a zero-chunk stream is valid, frames after close or abort are refused, and nonces over 64 bytes are rejected at parse time. Closed carries the bound but deliberately does not complete the JSON-RPC request, since CEP-41 still requires a final response. 26 CVM-41-* tests, 16 negative. Verified by mutation: indexing chunks by progress instead of chunkIndex, and treating any pong as liveness, each turn the suite red (7 failures). Module suite at 76.

JCS lands in quartz/utils as a generic primitive since ContextVM needs it twice (CEP-8's canonical invocation identity, CEP-15's schema hash) and nothing about it is ContextVM-specific. The number rule is the whole difficulty: RFC 8785 requires ECMAScript's Number::toString, which no JVM/Kotlin toString produces -- 1.0E30 where ECMAScript says 1e+30. The (s, n, k) formulation is implemented directly, including the exponential boundaries at 1e21 and 1e-7 and the plus sign on a positive exponent. A real divergence surfaced here and the edge-case test is what caught it: JVM prints Double.MIN_VALUE as 4.9E-324 while ECMAScript requires 5e-324, so the initial "trust the platform to already be shortest" approach would have hashed differently from every other conformant implementation. Digits are now shortened explicitly until the shortest form that still round-trips is found, which also removes the platform assumption entirely. CEP-15 sits on top: annotation keywords (title, description, examples, default, deprecated, readOnly, writeOnly) and x-* vendor extensions are stripped at every nesting level including inside arrays, then {name, inputSchema, outputSchema?} is canonicalized and hashed. The client-side rule is that the advertised schemaHash is a verification target rather than a label, so verify() recomputes from the tool definition and returns false on a mismatch instead of trusting it. Also replaced a raw U+000C that the editor had normalised into the source with its escape, per the CLAUDE.md rule, and scanned the rest of the new files. 13 CVM-15-* tests plus 17 JCS conformance tests. Module suite at 89.

Tag family, both lifecycles, the canonical invocation identity, and the negotiation state machine. The canonical identity is the part with teeth. A payment authorizes a future execution and the client is told to retry "the same request", so the identity is the client pubkey plus sha256(JCS({method, params})) with params._meta removed. The exclusion is load-bearing rather than tidy: MCP regenerates progressToken on every callTool, so without it two semantically identical invocations hash differently and a paid authorization could never be matched. It applies to identity derivation only -- semanticParams() returns a copy, so the full original params still reach the handler at execution time. The other rule with consequences is that neither side may silently fall back. PaymentSession makes a failed explicit_gating negotiation visible instead of degrading, and mayAutoPay() is the gate a handler must pass: a client that required visible payments will not settle a transparent payment_required it receives anyway. A handler that simply pays what it is asked violates the client half of CEP-8, so the refusal lives in the type rather than in a comment. Also covers the cap tag with fixed and inclusive-range prices, PMI validation against the W3C format with the -direct bearer suffix from CEP-21, the transparent notifications, and the -32042/-32043 error payloads. 31 CVM-8-* and CVM-21-* tests. Verified by mutation: including _meta in the identity, and dropping the visible-payments check, each kill exactly their guarding test. Module suite at 120.

01:55:21 +0000 Subject: [PATCH 009/148] feat(contextvm): CEP-4/19 encryption, CEP-6/17/23/24 discovery, CEP-35 learning Build items 3, 5, 6 and 15. CEP-4/19 gift wrap. The scheme is a simplified NIP-59: the inner kind-25910 event is signed first and the whole signed event is NIP-44 encrypted into the wrap, with no separate seal and no unsigned rumor. unwrap() verifies the inner signature, because the wrap's own signature only proves a throwaway key signed it -- without that check anyone able to encrypt to us could claim any pubkey. Each wrap uses a fresh key so two messages from one sender are unlinkable, and the NIP-59 timestamp is shifted and documented as unusable for ordering. EncryptionMode defaults to REQUIRED rather than mirroring the reference SDK's permissive default, and fails closed: under OPTIONAL a coordinator that simply never advertises encryption receives plaintext JSON-RPC on public relays. GiftWrapMode prefers the ephemeral 21059 but falls back to 1059 for a peer without it, since CEP-19 is additive and preferring it must never mean refusing to talk. Discovery covers CEP-6 announcements (11316-11320, newest kept per kind since they are replaceable), CEP-17 relay lists where the ContextVM profile is an unmarked r tag meaning both directions, CEP-24 review tagging including the asymmetry where a reply keeps the uppercase root on the announcement while the lowercase parent moves to the comment, and CEP-35 session learning where the first message each way sets the baseline and unknown tags are preserved with raw access. Also corrects a design error the crypto tests caught: CvmMessageEvent was an Event subclass whose create() claimed to return that subclass, but quartz mints event subclasses through its own kind-to-class factory, which knows nothing about 25910. Every event off the wire or out of a signer is a plain Event, so the subclass could only ever exist where we built one by hand and the cast failed at runtime. It is now a wrapper over Event, which is both honest and what the parsing side actually wanted. 40 new tests across CVM-4, CVM-19, CVM-6, CVM-17, CVM-24 and CVM-35, with the gift wrap round trip in jvmTest against real NIP-44 and secp256k1. Module suite at 152.

CvmTransport exposes request() and deliberately no public publish/subscribe pair. Kind 25910 is ephemeral, so a subscription opened after publishing has missed the response permanently and the failure looks exactly like a flaky relay; making the ordering the transport's job removes the whole class of bug rather than documenting it. Correlation checks both layers, the `e` tag against our request event and the JSON-RPC id against our call, and a notification never resolves a request -- CEP-41 is explicit that close does not complete it, and CEP-8 payment notifications arrive mid-request too. DualSigner makes the stable/ephemeral split explicit in the type so a caller cannot leak the account identity by omission. Everything defaults to ephemeral. CvmMcpClient covers the lifecycle, tool listing and tool calling, and always attaches a progressToken -- without one a server MUST NOT start either transfer profile, so omitting it would silently cap every response at one relay event. Both profiles are wired in: a CEP-22 transfer replaces the response that could not be published directly, while a CEP-41 stream delivers fragments alongside it and leaves the request to its own response. The fixture server is the piece the plan called out as missing. FixtureFaults can mismatch a response id, drop or forge the correlation tag, send a malformed body, go silent, or bury the answer under noise -- none of which a real server does, yet all of which a client MUST handle. InMemoryRelayPool drops an event nobody is subscribed to, which is what makes the subscribe-before-publish property genuinely tested instead of assumed; CVM-CORE-12 asserts the drop so CVM-CORE-11 cannot pass vacuously. It also implements CEP-16 injection, since that is a server obligation with no client-side test. 20 new tests. Module suite at 172 on jvm and 143 on the Android target (the difference is the secp256k1-dependent tests, which live in src/jvmTest). Verified by mutation: ignoring the reassembled CEP-22 payload, and letting a notification resolve a request, each kill exactly their guarding tests. Also adds contextvm/README.md recording the implemented spec revision (contextvm-docs e63bce6) as §6.7 requires, and updates the plan: Stage 2 is landed, and the §4.1 gate it carried was too broad -- ContextVM is credential-agnostic, so only Stage 3 depends on that decision.

Progress + sequences are also per-sender, so a `pong`'s progress bears no relation to + the `ping` it answers — they match by nonce alone. + +3. **`close` does not complete the request.** After a CEP-41 stream closes, the + originating JSON-RPC request still needs its own response, and a client must + never synthesize success from `close`. `ToolCallResult` carries `streamed` + fragments and the `result` separately for exactly this reason. + +## Testing + +```bash +./gradlew :contextvm:jvmTest # 172 tests +./gradlew :contextvm:testAndroidHostTest # 143 tests +``` + +The Android run is smaller because the tests needing real secp256k1 and NIP-44 +— the gift wrap round trip, the transport and the MCP client — live in +`src/jvmTest` where the JVM JNI artifact is on the classpath. Everything +protocol-level is in `commonTest` and runs on both. + +The suite is **Tier A and Tier C** from the plan's §6.4: rule-derived unit +tests, plus adversarial tests against `fixture/CvmFixtureServer`, which plays +the server role and can be told to violate any rule on demand (`FixtureFaults`). +Most tests are negative, because the CEPs are written as failure conditions. + +Still open: + +- **Tier B** — live integration against `ghcr.io/cordn-msg/cordn:latest`. +- **Tier D** — cross-implementation vector exchange for CEP-4 wraps and + CEP-22/41 framing.

Digits are shortened explicitly until the shortest round-tripping form is + found, which removes the platform assumption entirely. +3. **Event subclassing.** `CvmMessageEvent` began as an `Event` subclass whose `create()` claimed + to return that subclass, but quartz mints subclasses through its own kind-to-class factory, + which knows nothing about 25910. It is a wrapper over `Event` now. +4. **Subscribe-before-publish is an API-shape problem, not a discipline problem.** `CvmTransport` + exposes `request()` with no public publish/subscribe pair, and `InMemoryRelayPool` drops an + event nobody is subscribed to so the property is actually tested rather than assumed. + +Remaining gaps in this stage: Tier B (live integration against +`ghcr.io/cordn-msg/cordn:latest`), Tier D (cross-implementation vectors) and Tier E (a real +wallet for CEP-8) are all unstarted — see §6.4. `testAndroidHostTest` has not been run in a +container yet; Maven Central rate-limits the Android secp256k1 artifact. + +Original scope notes follow. + New Gradle module, peer of `:quic`. Depends on `:quartz` only; no Android framework deps. **Scope, CEP inventory, the fourteen subtle rules and the ordered build list are §6** — this stage is that From 4b4919819021ba30ed76b9cd9d69ad0d4c11019f Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 18 Sep 2026 14:54:00 +0000 Subject: [PATCH 011/148] refactor(contextvm): one package per CEP `quartz` puts a NIP's implementation under `nipXX`, `marmot` puts a MIP's under `mipXX`, and both keep named packages only for what no spec number covers. ContextVM had neither: CEP-4 sat in `crypto/`, CEP-6/17/23/24/35 were four unrelated specs sharing one `ServerDiscovery.kt`, CEP-8 in `payment/`. "Which file implements CEP-17" was a grep rather than a path. Now it is `cep17RelayList/ServerRelay`. Four placements are judgment calls, recorded in the README so they can be argued with: - CEP-19 stays inside `cep04Encryption/CvmGiftWrap`. Picking the wrap kind (21059, falling back to 1059) and building the wrap are one negotiation in one class; its own package would separate a method from its only caller. - CEP-16 gets no package. It is a `_meta` key name plus the server-side obligation to inject it -- a constant and fixture behaviour, not a subsystem. - `transfer/ProgressEnvelope` stays cross-cutting: CEP-22 and CEP-41 share that framing, so it is the `marmot/foundation/` analogue. - `core/`, `jsonrpc/`, `transport/` and `mcp/` keep names because the core draft spec is not a CEP and has no number to carry. Pure moves and package/import rewrites; no behaviour changed. Also drops a redundant cast the compiler flagged in `CvmMcpClient`. Suite unchanged at 172 on jvm and 143 on the Android target.

Only 3 of its 28 files import anything from `marmot/` at all. It already has a second consumer, and that consumer had to reach through the wrong package to get it: `quic/tls/TlsClient.kt` imports `quartz.marmot.mls.crypto.X25519` for its TLS 1.3 handshake, which is neither Marmot nor MLS. `:contextvm`/cordn will be the third, needing the engine without Marmot's bindings. So the engine moves to `quartz/mls/` and `marmot/` keeps everything else. Pure `git mv` plus the package rename across all six source sets (commonMain, jvmAndroid, appleMain, linuxMain, commonTest, jvmAndroidTest) and the five modules that reference it. No logic change: `:quartz:jvmTest` is 5074 before and 5074 after. The dependency still points the wrong way -- `mls/` retains 10 imports of `marmot/` -- which the next commits fix. Doing the move first keeps that diff small enough to read.

refactor(mls): move the group manager and stores to marmot/groups/ `MlsGroupManager` names `nostrGroupId` 147 times, stages Marmot's `group-lifecycle-v1` disband commits, and enforces MIP-01's "only admins may update group extensions". It is Marmot's binding layer, not the RFC 9420 engine, and every consumer outside quartz already says so: MarmotManager, MarmotInboundProcessor, MarmotOutboundProcessor, MarmotBenchmarks. `MlsGroupStateStore` and `MarmotMessageStore` go with it -- both are keyed on the hex Nostr group id from MIP-01's `h` tag, and nothing in the engine references either. That removes 2 of the engine's 10 `marmot/` imports without needing an interface: the two that were Marmot's, in code that was Marmot's. Names are unchanged on purpose. The package path already says whose manager this is, and renaming four classes would churn 22 files across five modules for clarity the path gives for free. After this the engine has no manager at all, so there is nothing for `MlsGroupManager` to be confused with. `:quartz:jvmTest` 5074, unchanged.

Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 18 Sep 2026 16:13:45 +0000 Subject: [PATCH 014/148] refactor(mls): put the binding's rules behind MlsGroupPolicy The engine knew the word "admin", which RFC 9420 does not have. MIP-03's authorization gate, the admin-depletion guard, the agent-text-stream role check on join and the self-demote-before-SelfRemove rule all ran inside `MlsGroup`, and `MlsGroup.create` defaulted every group to Marmot's leaf capabilities and `required_capabilities`. A plain RFC 9420 group could not be created at all -- every group came out requiring `marmot_group_data` -- and `commit()` derived its pre-commit secret under a hardcoded `MLS-Exporter("marmot", "group-event", 32)`. `MlsGroupPolicy` is the seam. Three hooks the engine calls where RFC 9420 defers to the application (authorizeCommit, authorizeSelfRemove, validateJoin) and four values it reads (leaf capabilities, required_capabilities, extra known extension types, the commit exporter label). `MarmotGroupPolicy` carries all of them, with the enforcement bodies moved verbatim. One argument now selects a whole profile: `MlsGroup.create(id, policy = MarmotGroupPolicy)` gets the rules, the capabilities and the exporter binding together, which is why the change is one added argument per call site rather than five. The default is permissive, and that direction is a deliberate trade. Closed would make the engine unusable without a policy and would push callers into writing an allow-everything one anyway. The cost is that a group restored without its policy silently drops the binding's rules -- a policy is behaviour, not state, so it is not in `MlsGroupState`. All ten production construction sites are in `marmot/` and all ten now name it. Policies see a read-only `GroupView`, not the group. A policy handed the `MlsGroup` could commit or rotate keys from inside the check meant to gate those things. The tests were the safety net, exactly as intended: the first run after the defaults changed failed 13, every one a Marmot test that had been relying on `MlsGroup.create` to make its group Marmot-shaped. Those now say so. The other ~180 construction sites kept passing on the permissive default, which is itself the result worth having -- they are engine tests and they no longer need Marmot to run. Adds 8 tests for the seam itself. Five pin the engine half with a recording policy (the hooks are consulted, a refusal aborts before the epoch moves, a refused SelfRemove is not staged, the exporter secret comes from the policy). Three pin the divergence from Marmot's side, including the half no other test covers: the same group at the same state accepts the same commit once the policy is gone. Verified by mutation -- ignoring the policy in `commit()` and re-hardcoding the exporter label each kill exactly their guarding tests. Also moves the last engine->marmot dependency out of `MlsKeyPackage`: `last_resort_key_package` is `draft-ietf-mls-extensions-10`'s component, not Marmot's, so it joins `app_components` and `safe_aad` in `ComponentsList` and `AppComponentIds` re-exposes all three. `quartz/mls/` no longer imports `quartz/marmot/` anywhere. Suite 5074 -> 5082, green.

That set is now `MarmotCapabilities.mipKeyPackageLeaf()`, beside the other two profiles, with the ordering marked load-bearing: those bytes go into published KeyPackages and define KeyPackageBundleStore's v4 snapshot format. `MarmotManager` and `MarmotConvergenceEngine` still spelled `exporterSecret("marmot", "group-event", 32)` literally at three call sites, so the binding's key derivation was stated in four places. They read it off `MarmotGroupPolicy.commitExporter` now, which is where the engine reads it too. `CurrentProfileWelcomeTest` and `CommitPreservesLeafIdentityTest` sat in the `mls/` test tree with ten and three Marmot imports between them; they test Marmot's current profile, so they move to `marmot/appComponents/`. The README states the invariant as a command you can run, and scopes it honestly: shipped code only. Two tests under `mls/components/` do decode real Marmot components, because an interop test is worth more against payloads that actually exist -- a fixture is data, an import in the engine is a dependency. It also writes down the three things a second binding has to know, the one that will bite (a policy is behaviour, not state, so a restore that forgets it silently drops the rules), and why the default is permissive rather than closed. The plan's Stage 1 is marked landed with what it cost and what Stage 3 still owes: MlsGroupManager names `nostrGroupId` 147 times, so cordn needs its own manager over the same MlsGroup rather than reusing that one. §5.1's coupling measurements are marked superseded rather than deleted -- they are what the stage was scoped against. Verified: :quartz:jvmTest 5082, :commons:jvmTest 2202, both green; :quic, :cli, :marmotBench and :amethyst all compile.

It takes both `:quartz` and `:contextvm` as `api`: a caller building a group holds MlsGroup and a caller configuring a coordinator holds CvmTransport, so neither is an implementation detail. Packages follow the spec documents, the way quartz follows NIPs: spec00…03 plus appGroupRef for the applications/ series. **CordnGroupPolicy** is what the MLS extraction was for -- one argument turns an MlsGroup into a cordn group, with `0xC04D` in capabilities, no required_capabilities (spec/01 §6 lets a group omit metadata entirely, and the reference client installs none) and `MLS-Exporter("cordn","group-payload",32)`. It deliberately leaves authorizeCommit at the default: cordn has no MIP-03. spec/01 §5.3 makes `admin_pubkeys` presentation metadata and nothing in the spec or the reference coordinator restricts who may commit, so **any member of a cordn group can commit anything MLS permits, including removing others**. That is recorded in the policy KDoc because a UI showing a cordn admin list as an access-control boundary would be lying. **CordnCredential** is the one line where §4.1 lives: 64 ASCII bytes of lowercase hex where Marmot uses the 32 raw bytes. spec/00 §6 requires "the canonical encoded Nostr public key" and then explicitly declines to say which encoding; the reference fixed it as hex-ASCII and the coordinator string- compares it to the calling event's pubkey. Still open upstream. **Empty admin_pubkeys means egalitarian**, permanently (spec/01 §5.3). Marmot reads the same empty set as "bootstrap, gate still open". Same bytes, opposite meaning -- which is why no authorization code is shared between the two. Three encoding findings worth carrying: 1. **spec/01 §3 contradicts itself.** It says "MLS variable-length vector encoding conventions" and then writes `opaque Name<0..2^16-1>`, which are different encodings. The reference emits a plain uint16 length, so that is what interoperates. Our test derives the 14 expected bytes by hand from the spec rather than round-tripping, because a round trip agrees with itself whichever one we picked. 2. **Group refs match the reference byte for byte.** The three golden strings in `packages/core/src/groupRef.test.ts` are cross-checked there against an independent TLV+bech32 assembly, so pinning them is a genuine cross-implementation vector (the plan's Tier D), not a record of our own output. All three matched on the first run. 3. **quartz's NIP-19 `Tlv.parse` is too lenient here.** It stops silently at a malformed tuple, which is right for an `nprofile` (a truncated one still names a usable pubkey) and wrong for a group ref, where dropping the tail turns a ref naming a coordinator into one that reaches for a default. cordn/appGroupRef parses strictly and still ignores unknown TYPES, which is the forward-compatibility rule spec §5 actually asks for. The seal is byte-identical to Marmot's kind-445 one and is separate code on purpose: same AEAD, nonce, empty AAD and base64 layout, different exporter label, and importing the Marmot one would put a later Marmot-side change on cordn's wire. Envelopes are unsigned by design (spec/02 §9), so `decode` requires the MLS sender identity rather than offering it -- without that cross-check any member could post as any other and no signature exists to contradict them. 24 tests. Coordinator client and sync engine are next.

That matters because it would work perfectly -- and tie every message to a real npub on a server that keeps ordered history forever. **The sync rules are the part where a mistake is silent**, so they are a pure state machine with the cursor advance inside it: - A self-echo is confirmation, not work. Feeding our own Commit back through MLS advances the epoch twice and nothing complains until messages stop decrypting several epochs later. Matching is on the sealed ciphertext, which is unique per posting because spec/03 §4 requires a fresh nonce -- cursor would break on renumbering, plaintext would mean decrypting our own traffic to recognise it. - Except when we posted and died before adopting the new epoch, where that echo is the only copy of the Commit we will ever be handed. - The cursor advances past everything, including undecryptable messages. One sealed under an epoch we never had is unreadable forever, so refusing to move past it stalls that group permanently. **Found a real hole in `:contextvm`'s fixture.** It answered every call with a constant JSON-RPC id, which passed all 172 contextvm tests because each made exactly one call -- and hung the first cordn test that made two. The handler now takes the request id, and two new contextvm tests pin what was untested: a second call correlates, and a stale id is ignored rather than resolving the wrong call. The production correlation logic was right the whole time; nothing had asked it the question. **CordnFixtureCoordinator** implements the eleven tools in memory and records which identity made each call. That is the only way to test the privacy claim of spec/00 §8: it is about what the coordinator LEARNS, so you have to stand on its side of the wire and look. Two tests do -- the message path never touches the stable key, and publication and admission always do, because a KeyPackage that did not name its owner would bind nothing. Verified by mutation: ignoring a pending self-echo, and advancing the cursor only for processed messages, each kill their guarding tests. The second needed a new end-to-end test first -- a single catch-up pass looks correct either way, and only a second pass reveals the stall. That is the shape of this bug in production too. 49 tests on jvm, 33 on the Android target. contextvm 172 -> 174. README records the five things that are easy to get wrong, what the coordinator learns, and the two spec/implementation divergences found while building.

Both are `api` +dependencies: a caller building a group holds `MlsGroup`, and a caller +configuring a coordinator holds `CvmTransport`. + +The plan (`quartz/plans/2026-09-17-cordn-interop.md`) said `quartz/…/cordn/`. +That was written before the dependency direction was settled. + +## Layout + +Packages follow the spec documents, the way quartz follows NIPs. + +| Package | Spec | What | +| ------- | ---- | ---- | +| `spec00Coordinator/` | `spec/00.md` | The eleven coordinator tools, the identity model, KeyPackage publication and its verification | +| `spec01GroupMetadata/` | `spec/01.md` | `cordn_group_metadata` (`0xC04D`) | +| `spec02Envelopes/` | `spec/02.md` | The unsigned Nostr-shaped application envelope | +| `spec03Payloads/` | `spec/03.md` | The ChaCha20-Poly1305 outer seal | +| `appGroupRef/` | `applications/group-ref.md` | `cordn1…` bech32 TLV references | +| `groups/` | — | The MLS binding: credential encoding, capabilities, `CordnGroupPolicy` | +| `sync/` | `spec/00.md` §4-5 | Cursors, self-echo reconciliation, fetch-then-subscribe | + +## Making a cordn group + +One argument turns an `MlsGroup` into a cordn group — capabilities, extension +registry and payload exporter all come from the policy: + +```kotlin +val group = MlsGroup.create( + identity = CordnCredential.of(myPubKeyHex).identity, + policy = CordnGroupPolicy, + initialExtensions = listOf(CordnGroupMetadata(name = "Design").toExtension()), +) +``` + +## Five things that are easy to get wrong + +1. **A cordn group has no admins in the enforcement sense.** `spec/01.md` §5.3 + makes `admin_pubkeys` *presentation* metadata, and neither the spec nor the + reference coordinator restricts who may commit. Any member can commit + anything MLS permits, including removing others. An empty list means + **egalitarian**, permanently — Marmot reads the same empty set as "bootstrap, + gate still open", which is why no authorization code is shared between them. + A UI presenting a cordn admin list as an access-control boundary would be + lying. + +2. **The credential is 64 ASCII bytes of hex, not 32 raw bytes.** `spec/00.md` + §6 requires "the canonical encoded Nostr public key" and explicitly declines + to say which encoding. The reference fixed it as hex-ASCII; Marmot picked + raw. One KeyPackage cannot satisfy both, and it is a one-line change on + either side today. Still open upstream — plan §4.1. + +3. **A self-echo is confirmation, not work.** A Commit we posted comes back + through the same stream as everyone else's traffic. Feeding it through MLS + again advances the epoch twice, and nothing complains until messages stop + decrypting several epochs later. Matching is on the sealed ciphertext, which + is unique per posting because the nonce is fresh (`spec/03.md` §4). + +4. **The cursor advances past messages you skip.** Including undecryptable + ones. A message sealed under an epoch we never had is unreadable forever, so + a cursor that refused to move past it would stall that group permanently + with no error anywhere. Only a *second* catch-up reveals the bug. + +5. **Encryption must be pinned.** The ContextVM SDK defaults `encryptionMode` + to `OPTIONAL`, which resolves from negotiated session state, so a coordinator + that simply does not announce `support_encryption` gets plaintext JSON-RPC on + public relays — `gid`s, target pubkeys, KeyPackages and cursors, readable by + any relay operator. `:contextvm`'s `CvmGiftWrap` defaults to `REQUIRED` and + fails closed. Do not undo that. + +## What the coordinator learns + +Content: nothing. Double-sealed, and it cannot tell a Commit from a chat line. + +Metadata is the cost, and the stable/ephemeral split in `CoordinatorMethod` is +how it is managed — the identity is fixed per method, not a parameter, so +`msg_post` cannot accidentally ride your real npub. The split is real but +partial: + +- **Admission is in the clear on both ends.** `join_request_store` names your + real key and the `gid`; `welcome_store` names the target's and `welcome_take` + is called by it. For any group joined through a share link the coordinator + observes real-identity membership directly. Structural, not a bug. +- **The ephemeral key is per session, not per message.** One pseudonym touches + every group you hold on that coordinator, so that `gid` set is a stable + fingerprint linking them. `CoordinatorClient` takes its signers from the + caller precisely so the caller decides how often to rotate. + +Plan §8 has the full analysis. + +## Two spec/implementation divergences found + +1. **`spec/01.md` §3 contradicts itself**: "MLS variable-length vector encoding + conventions" and then `opaque Name<0..2^16-1>`, which are different + encodings. The reference emits a plain uint16 length. We match the + reference, and the test derives the expected bytes by hand from the spec + rather than round-tripping — a round trip agrees with itself whichever one + you picked. +2. **KeyPackage publication rides JSON-RPC envelope shape**, not a stable + schema: `spec/00.md` §7's "signed publication payload" is the `kp_publish` + request event, and the KeyPackage is recovered by parsing JSON-RPC out of its + `content`. The reference client already carries a fallback from one rename + (`kp_64 ?? keyPackageBase64`); so do we. Worth proposing upstream that + publication gets its own payload or kind — it would also let a cordn + KeyPackage be published to relays and consumed with no coordinator at all. + +## Testing + +```bash +./gradlew :cordn:jvmTest # 49 +./gradlew :cordn:testAndroidHostTest # 33 +``` + +The Android run is smaller because the tests needing real secp256k1 — anything +driving a coordinator over a live transport — live in `src/jvmTest`. + +`fixture/CordnFixtureCoordinator` implements the eleven tools in memory and +**records which identity made each call**, which is the only way to test the +privacy claim: it is about what the coordinator learns, so you have to stand on +its side of the wire and look. + +The group-ref tests pin the three golden strings from the reference's own suite +(`packages/core/src/groupRef.test.ts`), where they are cross-checked against an +independent TLV+bech32 assembly. That makes them a genuine cross-implementation +vector — the plan's Tier D — rather than a record of our own output. + +Still open: + +- **Live integration** against `ghcr.io/cordn-msg/cordn:latest` (Tier B). +- **Group creation and messaging end to end.** The pieces are each tested; a + test that creates a group, adds a member through a Welcome and exchanges a + sealed envelope needs the Stage 0 interop vectors. +- **Multi-device** is an explicit non-goal — `spec/applications/multi-device.md` + ships a ts-mls-internal serialization, not an MLS wire format.

The reference emits a plain uint16, so that is what + interoperates. Our test derives the bytes by hand from the spec, because a round trip agrees + with itself whichever encoding we had picked. +3. **Group refs match the reference byte for byte** on the first run. The three golden strings + in `packages/core/src/groupRef.test.ts` are cross-checked there against an independent + TLV+bech32 assembly, so pinning them is a real Tier D vector. +4. **quartz's NIP-19 `Tlv.parse` is too lenient for a group ref.** It stops silently at a + malformed tuple — right for an `nprofile`, wrong here, where dropping the tail turns a ref + naming a coordinator into one that reaches for a default. `appGroupRef` parses strictly and + still ignores unknown types. +5. **`:contextvm`'s fixture could not answer a second call.** It echoed a constant JSON-RPC id, + which passed every contextvm test because each made exactly one call, and hung the first + cordn test that made two. The handler now takes the request id, and two contextvm tests pin + the behaviour: a second call correlates, and a stale id is ignored rather than resolving the + wrong call. + +Verified by mutation: ignoring a pending self-echo, and advancing the cursor only for processed +messages, each kill their guarding tests at both the unit and end-to-end level.

Reading it found three defects that no amount of self-consistent testing would have. **1. `authenticated_data` is a wire requirement the cordn spec never mentions.** The reference client puts the sender's account pubkey in MLS `authenticated_data` and REJECTS any application message that arrives with it empty (packages/cli/src/groupSync.ts:247). Our engine AEAD-bound the field correctly on receive but hardcoded ByteArray(0) on send and never exposed it -- so we would have shipped a client every cordn peer silently discarded, with our own tests perfectly green. MlsGroup.encrypt now takes it, DecryptedMessage carries it, and CordnApplicationMessage owns the binding and treats an empty AAD as a rejection rather than an unknown sender. **2. Our GroupContextExtensions check implemented a rule RFC 9420 does not have, and omitted the one it does.** §12.1.7 says nothing about recognising extension types; its only validity rule is that the resulting group must not require capabilities some member lacks. We rejected any type outside a hardcoded list -- which refuses cordn's 0xC04D metadata commit outright -- and never checked the real rule, so a commit could install a required_capabilities a sitting member could not meet and split the group. Both directions fixed, enforced over the post-commit membership so the RFC's "including those added, excluding those removed" falls out for free. `MlsGroupPolicy.knownExtensionTypes` is removed: it encoded the invented rule. I verified this against the RFC text rather than taking the claim at face value -- Staircase describes the rule as "every member advertises the type", which is not what §12.1.7 says either. **3. `Ed25519` could not rebuild a key pair from a known seed.** Any interop fixture needs it, and ts-mls stores only the seed, inside a PKCS#8 blob. `keyPairFromSeed` added across the expect/actual set. **The lifecycle test** walks a whole group from the other side of the wire, against fixtures ts-mls generated: read their KeyPackage and agree on its kp_ref, recognise their last-resort carrier, unseal their commit under the published epoch-0 exporter, join from their Welcome, derive the same epoch exporter byte for byte, apply their metadata commit, advance to epoch 2 and agree again, and read both application messages end to end. The exporter assertions carry the most: it sits at the end of the whole key schedule, so a one-bit divergence anywhere upstream gives 32 completely different bytes. Also: cordn frames handshake messages as PrivateMessage where Marmot uses PublicMessage, so `decrypt` is the entry point and `processFramedCommit` is not. And `MlsGroup.memberIdentityHex` hexes the credential bytes -- right for a raw-key binding, 128 characters of hex-of-hex for cordn -- so cordn has its own accessor and the trap is now documented where it bites. Mutation-checked: dropping the AAD in either place kills the send-direction tests. Those tests exist because the first mutation run survived -- the ts-mls fixtures only cover the receive direction, so nothing noticed our own encrypt had stopped writing the field. quartz 5082 -> 5086, cordn 49 -> 69. Staircase also independently confirms Stage 1: their VENDORED.md lists the same Marmot decoupling we landed, arrived at separately as patches against a fork. Now that the seam is upstream they could stop forking, and their remaining patches are a ready-made list of what a cordn binding still wants from the engine.

A client can parse everything correctly and still emit something nobody accepts, and that failure is the worse one: our own tests stay green while every peer silently drops us. `KotlinArtifactProducerTest` builds a group under CordnGroupPolicy, adds a real ts-mls KeyPackage (bob2, from their fixtures -- using one of ours would make it a test of our encoder talking to itself), sends an application message, and commits a metadata change, writing the nine artifacts Staircase's verify.ts reads. `cordn/interop/verify-with-ts-mls.sh` hands them to ts-mls. Ten checks, all passing on the first run: ts-mls joins from our Welcome at epoch 1, decodes our cordn_group_metadata extension, derives the same epoch-1 exporter, decrypts our application message, finds our pubkey in the AAD, matches the envelope id and content, applies our metadata commit, advances to epoch 2, and derives the same epoch-2 exporter. Confirmed non-vacuous: flipping one nibble of k-exporter-e1.hex fails exactly that check and exits 1, with the other nine still passing. **Run it under Node, not bun.** Staircase's own run.sh uses bun, and bun's WebCrypto has no X25519 DHKEM, so ts-mls there cannot open a Welcome at all -- not even one it generated itself. I only established that by having ts-mls try to join its OWN Welcome, which failed identically; without that probe the `DecapError: The algorithm is not supported` deep inside HPKE reads exactly like a wire-format mismatch in our Welcome. Worth reporting upstream -- it is a one-line change to their runner. The gate is a script rather than a test because it needs a cordn checkout with `pnpm install` and a staircase checkout, which this repo's CI does not carry. The producer half runs unconditionally in :cordn:jvmTest, so the artifacts and our own round trip are always covered. Still skipped: verify.ts's optional ts-mls ClientState gate. Producing one means re-encoding MlsGroupState into ts-mls's layout, which only matters for multi-device -- an explicit non-goal. cordn 69 -> 70.

A consequence of an earlier choice was written down as if it were a constraint. `:contextvm`'s reason was "a peer of `:quic`". That analogy does not hold. `:quic` is a transport library with no Nostr in it at all -- which is exactly why it is a module. ContextVM is nothing but Nostr: kind 25910 events, NIP-59 gift wraps, relay subscriptions. Its build file also claimed quartz's serialization dependency was not transitive, which only mattered across a boundary the same decision had created; quartz has had kotlinx-serialization-json all along. What actually governs is the precedent already in the tree. `marmot/` is 18,876 LOC of non-NIP protocol family living inside quartz with its own MIP spec series -- the same shape as cordn and three times the size of both modules combined. `concord/` is another, `buzz/` a third. CLAUDE.md's own rule is that quartz holds implementations of Nostr specifications, and CEPs are to ContextVM what NIPs are to Nostr core. So: `quartz/…/contextvm/` and `quartz/…/cordn/`, as the plan said in the first place. Two build files and two settings entries deleted. Two things got better rather than just tidier: - **Both now build for every quartz target**, iOS and linuxX64 included. Neither had a single platform-specific file, so as jvm+android modules they were narrower than the code required. Verified with `compileCommonMainKotlinMetadata`, which type-checks commonMain against the intersection of all declared targets. - **The crypto-dependent tests moved from `jvmTest` to `jvmAndroidTest`**, where quartz keeps the rest of its secp256k1 tests, so they now run on the Android host too instead of the JVM alone. `:quartz:jvmTest` 5086 -> 5330, exactly the 174 + 70 that moved, none lost. The ts-mls interop gate still passes all ten checks after the move. `:quartz:testAndroidHostTest` has four failures in `NostrServerTest` and `LiveNegentropyIndexStoreTest`. They are pre-existing and unrelated -- relay server and SQLite store -- confirmed by stashing this change and reproducing them identically at the parent commit. CLAUDE.md now records the placement rule, so the next protocol does not have to rediscover it: a protocol over Nostr is a quartz package, not a module; `quic`/`nestsClient`/`marmotQuic` are modules because they carry no Nostr.

65c683c9c76e75a1deba033bcaccd24ad83d0b9f Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 18 Sep 2026 21:36:33 +0000 Subject: [PATCH 021/148] fix(store): classify insert failures against the database, not the driver's message MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `classifyRowError` read SQLite's exception text to decide whether a row that failed to insert was a duplicate, a superseded replaceable, or a genuine write failure. That text is the driver's business, not a contract: the bundled JVM driver spells out `UNIQUE constraint failed: event_headers.id`, while Android's wraps the same failure in an `android.database.SQLException` whose message is **null**. So on the Android host every duplicate fell through to `Failed`, which the relay renders as `OK false "error: SQLException"` — an answer clients retry forever, and a direct violation of STORE-W01/W02 (`OK true` with the `duplicate:` prefix). Four commonTest suites caught it and failed on that target only: NostrServerTest x3 and LiveNegentropyIndexStoreTest. The classifier now asks the connection instead. It already runs after the savepoint rollback, so the connection shows pre-insert state and the two questions have exact answers: is this id already stored, and does a stored version already beat this one at its replaceable/addressable coordinate? The latter is the exact complement of `displacedBy`'s predicate, so a disk error while inserting a *winning* version still reports `Failed` rather than turning into a silent `OK true`. Trigger RAISEs (`blocked:`, `not allowed`) keep being decided by text — they leave no database-visible trace. One behaviour change, noted in the skill's changelog: re-offering a stored replaceable/addressable event byte-for-byte now reports DUPLICATE where the JVM driver previously reported SUPERSEDED. It violates both indexes and which one SQLite names first is up to the driver; the id answer is the one that holds everywhere (and is the truer sentence). Both carry the `duplicate:` prefix, so the wire answer is unchanged. `InsertOutcomeClassificationTest` pins all of this at the store level on both targets, including the guard that a winning version at an occupied coordinate is still Accepted. Also corrects a false claim in the previous commit's message: moving the cordn and contextvm tests to `jvmAndroidTest` did NOT make them run on the Android host. `androidHostTest` has no `dependsOn(jvmAndroidTest)` — only `jvmTest` does — so those suites run on the JVM target alone.

That covers the crypto layer and says nothing about the layer above it: the eleven coordinator tools, their argument names, which fields are optional, and the `cordn1…` group ref. That layer rested on our reading of the spec. `quartz/tools/cordn-vector-gen` closes it from their side. It generates `resources/cordn/coordinator-contracts.json` from `@cordn/core` (MIT) -- the package their reference coordinator and client both import -- by handing each payload we send to their zod schema, so a field we named wrong fails at generation time. Each method also carries a `rejects` set their schema must refuse, because a positive only means something if the schema is strict where we assume it is. Group refs round-trip through their bech32 codec. - CoordinatorContractVectorTest (15): drives CoordinatorClient through the real ContextVM transport, asserts the arguments the coordinator sees equal those vectors, then replays their result shapes back through our parser. - CordnGroupRefVectorTest (5): both directions, including the uppercase form (their `decodeGroupRef` accepts it though their `isGroupRef` screen does not) and a non-ASCII gid, which §4.1 requires to survive byte for byte. - CordnFixtureCoordinator now records each call's arguments and can serve a scripted result, which is what lets the same fixture do both directions. Mutation-checked, since 20 tests passing on the first run means nothing on its own: sending `after = 0` on a first-ever fetch instead of omitting it, and flipping the group-ref TLV emission to ascending order, each killed exactly one test. The TLV mutation was caught only by the encode-direction test -- decoders accept any order by spec, so a decode-only suite would have shipped that divergence. Also settles §4.1 (credential encoding) by implementing both rather than waiting on an agreement neither ecosystem has an incentive to reach. Marmot writes a pubkey as 32 raw bytes, cordn as 64 ASCII hex bytes; they are mutually exclusive by length, so no leaf can be misread as the other profile's. BothCredentialProfilesTest runs both groups on one engine and pins the `memberIdentityHex` hex-of-hex trap that would otherwise drop cordn members from a member list. Two findings recorded in the plan: - Tier B is blocked on licensing, not tooling. `packages/coordinator`, `packages/server` and `packages/test-utils` carry no LICENSE file and no `license` field, and neither does the repo root -- so the reference coordinator, and the ghcr image built from it, are unlicensed. Only `packages/core` and `packages/cli` are MIT. The plan's claim that "everything under Cordn-msg is MIT" was wrong and is corrected. - Their current `kp_publish` schema rejects the legacy `keyPackageBase64` field, so our fallback is for parsing old publication events only.

What the two share is the RFC 9420 engine underneath. Its store is separate from MlsGroupStateStore for the same reason: `nostrGroupId` and `gid` look alike and mean different things. `ICoordinator` (quartz) makes the eleven tools a contract so the cursor loop and the manager can be driven without a relay. It adds no behaviour and deliberately exposes no identity parameter -- which key signs which call is fixed by CoordinatorMethod per spec/00.md §8, and a substitute implementation cannot widen that. `CordnExposure` turns §8 into a model instead of a comment. The plan requires that exposure be "surfaced, not buried" because a cordn group and a Marmot group are not privacy-equivalent and a user cannot infer that from either one looking like a group chat. GroupExposure computes it from real state -- notably §8.2's linked-group count, which is the part nobody guesses -- so a UI renders facts rather than prose. Nothing renders it yet; that is the remaining Stage 4 work. Four bugs the tests found, each documented in the plan: - CommitResult.commitBytes is the bare RFC 9420 Commit struct, not an MLSMessage. Posting it produces a payload no receiver can parse. - The pre-commit epoch rule (spec/03.md §5) is invisible to a two-party test: sealing a Commit under the epoch it creates still passes create -> invite -> join -> read, because the joiner's Welcome cursor skips the only Commit in the stream. It takes a third member to catch. Confirmed by mutation -- the new three-member test is the only one that dies. - A Welcome does not carry the gid. spec/03.md §2 decouples it from the MLS group_id; the reference client closes the gap with `group_id = utf8(gid)`, which staircase's fixtures confirm. We follow the convention and treat it as an observation: a non-UTF-8 group id yields a named skip, not a mojibake key that fetches nothing forever. MlsGroup.create gained an optional groupId. - Public-framed handshake messages interoperate. Checked in their code rather than assumed: mlsMessages.ts:68 accepts wireformat 1 and 2 and hands both to ts-mls's processMessage. `amy cordn ref encode/decode` and `amy cordn exposure` ship; ref encode produces byte-identical output to cordn's own vector. The coordinator-driving verbs do not, and the reason is in the file: Tier B is blocked on licensing (§7), so there is nothing to exercise them against, and unexercised coordinator verbs are a guess with a command-line interface.

It takes a third member — one + already in the group when a later Commit lands — to catch it. `CommitResult` already hands + back `preCommitExporterSecret` precisely because the key is unobtainable afterwards. +3. **A Welcome does not carry the `gid`.** `spec/03.md` §2 decouples the delivery id from the MLS + `group_id`, so in principle a joiner cannot know where to fetch from. The reference client + closes the gap by convention — `group_id = utf8(gid)` — which staircase's fixtures confirm + (their `group_id` decodes to exactly their published `gid`). We follow the convention and + treat it as an observation, not a guarantee: a non-UTF-8 group id yields a named skip rather + than a mojibake key that fetches nothing forever. `MlsGroup.create` gained an optional + `groupId` so our groups carry it too. +4. **Public-framed handshake messages interoperate.** Our engine frames Commits as + `MLSMessage(PublicMessage)`; cordn's client emits private framing. Checked rather than + assumed: `packages/cli/src/utils/mlsMessages.ts:68` accepts wireformat 1 *and* 2 and hands + both to ts-mls's `processMessage`.

A Marmot group and a cordn group have materially different metadata exposure and users cannot infer that from either one looking like a group chat." GroupExposure existed so there would be something to render; this renders it. The disclosure sits where it can still change a decision — on a pasted cordn1… link, before joining, rather than in a settings page nobody opens. The screen reads the link, names the coordinator and its relays, and shows the exposure. It deliberately does not join: joining needs a live coordinator and Tier B is blocked on licensing (§7), so a join button would be half a feature whose other half has never been run. - commonsUI/.../cordn/ui/: CordnExposureCard, CoordinatorHealthRow, CordnGroupBadge. Material3 only, so Desktop gets them for free. - commons/.../CordnLinkInspection: parse-and-disclose, headless and tested, so the screen only draws. A ref naming no coordinator is valid but not followable, and carries no exposure — inventing a threat model for a server we cannot identify would be worse than saying nothing. - Settings → Cordn group link, with a route and search keywords. Rendering it found two bugs compiling could not: - The severity colours were not monotonic. `tertiary` for the middle level rendered pink against a dark `onSurface` for the worst one, so "under a throwaway key" read as more alarming than "tied to your real account". Emphasis for the worst case is now weight rather than another hue. Nothing uses `error`: everything on the card is how cordn works, not a fault, and painting normal operation red teaches people to ignore red. - Note order is part of the disclosure. Cross-group linkage (§8.2), the item nobody predicts, sat below message padding, the least consequential one. notes() now returns most-surprising-first. CordnExposureRenderTest rasterises the surface headlessly (ImageComposeScene, software Skia, no display, no new dependency — the same Compose Desktop artifact jvmMain already uses) and asserts on pixels. It catches what a compile cannot: a missing string resource, which throws at render because the generated Res.string.* accessors compile regardless, and a composable that draws nothing. Mutation-checked — hardcoding the card background and disabling the §8.2 conditional each kill exactly one test. The first version of the theme test sampled only the page background and let the hardcoded card through, so it now samples inside the card as well.

Emphasis for the worst case is now weight, not another hue; + nothing uses `error`, because everything on the card is how cordn works, not a fault. +2. **Note order is part of the disclosure.** Cross-group linkage (§8.2) — the item nobody + predicts — was below message padding, the least consequential one. `notes()` now returns + most-surprising-first. + +`CordnExposureRenderTest` keeps both honest by rasterising the surface headlessly +(`ImageComposeScene`, software Skia, no display) and looking at the pixels. It catches the two +things a compile cannot: a missing string resource, which throws at render because the generated +`Res.string.*` accessors compile regardless, and a composable that draws nothing.

Three findings shape the plan: - Most of this UI already exists, for Marmot -- 3,308 lines under chats/marmotGroup/. So the first decision is not which screen to build but whether the two bindings share a chat UI. The plan rejects adapting cordn messages into Note/LocalCache (an unsigned, relay-less message escaping into relay-bound code is a confidentiality bug, not a rendering bug), recommends parallel screens now, and a shared commonsUI surface once the duplication is concrete rather than predicted. - The gate is not a screen. Nothing constructs a CordnGroupManager for an account, wires a transport, publishes key packages or persists state. That runtime is Stage A and most of the risk; every screen is cheap after it. - Their message-kind catalog diverges from ours where the spec is silent: edits are 1010 to Marmot's 1009, pins (1011) have no Marmot equivalent, and system rows are derived client-side rather than sent on the wire (kind 1210). spec/02.md §6 blesses none of them, so these are app conventions two apps picked differently -- written up as decisions rather than assumed. Also records what stays out: multi-device remains a non-goal because the spec ships serialized ts-mls ClientState, which is a library's internals and not a wire format, so there is nothing interoperable to implement. Verification is honest about its ceiling: Tier B is still blocked on licensing, so every stage can be checked against the in-memory coordinator, the ContextVM fixture and the vectors -- and none of it against a live deployment. Whether to ship on that basis is called out as a product decision, not a technical one.

The decision to make first: share the chat UI, or parallel it? + +Three options. + +**(A) Adapt cordn messages into `Note` + `LocalCache`.** Every existing feed/chat composable works +untouched — reactions, replies, media, rich text, the lot. +*Cost:* `LocalCache` is the note graph for relay events. Cordn envelopes are unsigned +(`spec/02.md` forbids `sig`), have no relay provenance, and must never leak into a relay-facing +query, an outbox calculation or a NIP-65 decision. Marmot already does something like this and +the seams show. Risk: a cordn message escaping into relay-bound code is a confidentiality bug, +not a rendering bug. + +**(B) Parallel screens under `chats/cordnGroup/`.** Total isolation, zero risk of (A)'s failure +mode, and the fastest first screen. +*Cost:* ~3,000 duplicated lines, two places for every future chat fix, and two divergent UXs for +what the user sees as "group chat". + +**(C) Extract a binding-agnostic chat surface into `commonsUI`, drive it from both.** A +`GroupChatroom` interface over "ordered messages with sender, kind, tags, content, reactions, +edits", with Marmot and cordn adapters; the screens take the interface. +*Cost:* the extraction is the work. The Marmot screens are Android-only and `LocalCache`-bound, so +this is a real refactor of shipped, working code — with Marmot regressions as the risk, and no +cordn user yet to justify it. + +**Recommendation: (B) first, then (C) — and never (A).** + +(A) is rejected on the confidentiality argument: the cost of the failure is worse than the cost of +duplication, and it is the kind of failure that is invisible until it isn't. + +(B) first because the cordn runtime (Stage A) is where the real unknowns are, and we should not +refactor Marmot's shipped UI while the thing we are refactoring *for* has never run end to end. +(C) becomes the obvious move once the cordn screens exist and the duplication is concrete rather +than predicted — at which point the extraction is mechanical and driven by two real callers +instead of one real and one imagined. + +**Do not start (B) by copying `MarmotGroupChatScreen`.** Build the smallest cordn chat screen +that works and let (C) reconcile them later; a copied 1,154-line info screen is duplication we +would have to unpick twice. + +## 4. Plan + +Each stage lists how it is verified. Note throughout: **Tier B is blocked** (interop plan §7 — +the reference coordinator is unlicensed), so nothing below can be checked against a live cordn +deployment. What *can* be checked: the in-memory coordinator (`FakeCoordinator`), the ContextVM +Tier C fixture server, and the ts-mls/`@cordn/core` vectors. Every stage below is verifiable that +way; none of them is verified against cordn.net until §7 of the interop plan is resolved. + +### Stage A — the account-level runtime (blocks everything) + +No UI. This is the gap between "`CordnGroupManager` has tests" and "an account has cordn groups". + +1. **Wire the transport.** `CvmTransport` over Amethyst's relay pool, with the account signer as + the stable identity and a per-session ephemeral signer (`spec/00.md` §8; the split is already + enforced by `CoordinatorMethod`). Encryption pinned `REQUIRED` — `:contextvm`'s `CvmGiftWrap` + defaults that way and nothing here may undo it (§8.6). +2. **A per-account, per-coordinator manager registry.** One `CordnGroupManager` per coordinator + (its KDoc explains why: a `gid` is only unique within one). Lifecycle tied to the account. +3. **Persistence.** An Android `CordnGroupStore` — encrypted at rest, like + `AndroidMlsGroupStateStore`. The interface exists; the actual is missing. +4. **Key-package lifecycle.** Generate, store the private half, publish, track which `kp_ref` maps + to which bundle, rotate. cordn has no event kind for this (§4.2), so it is all coordinator + calls plus local storage — none of Marmot's rotation machinery transfers. +5. **A foreground sync loop.** `catchUp` then `subscribe` per coordinator, feeding a store the UI + observes. + +*Verified by:* an integration test driving two accounts through the Tier C fixture end to end — +publish, invite, join, send, receive — with the real transport rather than `FakeCoordinator`. + +### Stage B — groups exist and are visible + +6. **A cordn chatroom model + ViewModel** in `commons` (`model/cordnGroups/`, beside + `marmotGroups/`), fed by `CordnGroupManager.Delivery`. Messages keyed by envelope id + (`spec/02.md` §7 — the cursor is a delivery primitive, never a message identity). +7. **Group list**, with `CordnGroupBadge` (built, unused) on every row. +8. **Minimal chat screen**: ordered messages, sender, send a kind-9. No reactions, no media yet. +9. **Group info**: metadata, members, admins, epoch, coordinator, `gid`, share ref, and the + **`CordnExposureCard`** (built, and this is its real home — the link screen was the pre-join + half of the same disclosure). + +*Verified by:* commons tests on the model; render tests on the new composables, the way +`CordnExposureRenderTest` does it. + +### Stage C — joining and being joined + +10. **Welcome inbox surface** — "X invited you to join", accept/decline, wired to + `joinPendingWelcomes`. The skip reasons that method already returns are user-facing text. +11. **Join requests** — `join_request_store` from a share link; the admin side lists pending + requests and completes them (take key package → verify → Add+Commit → `welcome_store`). +12. **QR share + scan**, reusing Amethyst's existing QR components. +13. **Create group**, including choosing a coordinator and the `gid` (their client uses a random + UUID; anything unique works and it must not be derived from the MLS `group_id`, which is + secret). + +*Verified by:* a two-account fixture test covering link → request → accept → first message. + +### Stage D — message features + +14. Reply (1111), reaction (7), delete (5) — the three that are spec-suggested and match Marmot. +15. **Edit and pin** — only after §5.1 is decided. +16. Drafts, unread state, mentions, pinned ribbon. +17. **Encrypted media**: the cordn codec (§4.5), then image/file send and view over Blossom. +18. Voice notes, if we want parity; Amethyst has audio recording already. + +*Verified by:* codec vectors for media (generated the way `cordn-vector-gen` does), fixture tests +for the rest. + +### Stage E — settings + +19. Coordinator management screen (add, remove, purge, health, server info). +20. Key-package screen (create, publish, directory, last-resort). +21. Backup/restore — **only if** we decide cordn state belongs in Amethyst's existing backup + story rather than a cordn-specific one. + +## 5. Decisions this plan needs + +### 5.1 Edit and pin kinds — we cannot have both conventions + +Marmot edits are **1009**, cordn-web edits are **1010**, and pins (**1011**) exist only in +cordn-web. The spec blesses none of them. Three ways: + +- **Follow cordn-web inside cordn groups** (1010/1011) and keep 1009 for Marmot. Interoperable + with the only other cordn client; costs a per-binding kind table, which we need anyway since + system rows already differ. +- **Use 1009 everywhere.** One table, and our cordn edits silently do nothing in their client. +- **Ship neither until upstream specs them.** Edits and pins degrade honestly — an unknown kind + renders as an ordinary message rather than corrupting one. + +**Recommendation: follow cordn-web.** Being the second implementation of an unspecified +convention is how it becomes specified, and a per-binding kind table is a small, well-contained +cost. Worth raising upstream as "please write these down", alongside the §4.2 and LICENSE asks. + +### 5.2 System rows are structurally different + +Marmot puts system events **on the wire** (kind 1210, a real envelope). cordn-web **derives** them +client-side from Commits and never transmits them (synthetic kind `-1`). Deriving is strictly +better here — it cannot disagree with the MLS state it describes, and it costs no bytes — and it +is what a cordn peer will do anyway. Take theirs for cordn. Do not change Marmot. + +### 5.3 Multi-device stays a non-goal + +`spec/applications/multi-device.md` ships `base64(serialized ts-mls ClientState)` inside sealed +documents. That is **their library's internal state**, not a wire format — nothing but ts-mls can +produce or consume it, so there is nothing interoperable to implement. The interop plan already +records this (§4.6) and it should stay recorded rather than quietly reappearing as a settings +screen. If upstream ever specifies a library-neutral device-sync format, revisit. + +### 5.4 Which backup story + +cordn-web has its own passphrase-encrypted backup. Amethyst has account backup already. Folding +cordn group state into Amethyst's backup is better for users and worse for portability (their +file will not import). Needs a call; no strong opinion here. + +## 6. Out of scope, and why + +- **News feed, donations, supporters** — cordn.net product surface, not protocol. +- **Theme editor / gallery** — Amethyst has its own theming. +- **App update banners, native bridge/shims** — packaging concerns of a web app shipped as a + native wrapper. +- **Profile pages, "why" page** — Amethyst has these. +- **Multi-device** — §5.3. + +## 7. Risks + +1. **Stage A is most of the work and all of the uncertainty.** Every screen is cheap once an + account really holds cordn groups; nothing is possible before that. +2. **No live verification.** Tier B is blocked on licensing, so "works against the fixture" is the + strongest claim any stage below can make. Shipping a chat feature to users on that basis is a + product decision, not a technical one — it should be made deliberately, and probably means + shipping behind a flag until a licensed coordinator exists to test against. +3. **The (B)→(C) refactor is a promise that can rot.** If cordn ships and the extraction never + happens, Amethyst carries two group-chat UIs indefinitely. Worth a follow-up plan the moment + Stage B lands, rather than a line in this one. +4. **§8 exposure must ride along.** The badge and the card exist; if the group list and info + screens ship without them the disclosure requirement quietly regresses to what it was before. + +## 8. Open questions + +1. Do we ship cordn to users at all before a licensed coordinator exists to test against (risk 2)? +2. §5.1 — follow cordn-web's 1010/1011, or wait for a spec? +3. §5.4 — one backup story or two? +4. Is there appetite for (C), the shared chat surface, or is Marmot's UI effectively frozen? +5. Whose coordinator do we default to, if any? The interop plan's open question 5 applies harder + once there is a UI with a "use default" button: shipping a default is an endorsement. diff --git a/amethyst/plans/README.md b/amethyst/plans/README.md index 1aebbcf8fa..75a44db027 100644 --- a/amethyst/plans/README.md +++ b/amethyst/plans/README.md @@ -11,6 +11,7 @@ _Audited 2026-06-30. 21 plans: 19 shipped (archived), 1 in-progress, 1 queued, 0 ## Queued | Plan | Summary | | ---- | ------- | +| [2026-09-19-cordn-ui.md](2026-09-19-cordn-ui.md) | Every user-facing feature cordn-web has, mapped onto Amethyst — the account-level cordn runtime (the real gate), group list/chat/info screens, welcomes, join requests, message features and settings; recommends parallel cordn screens now and a shared chat surface later, and flags the 1009-vs-1010 edit-kind divergence. | | [2026-07-23-push-notification-redesign.md](2026-07-23-push-notification-redesign.md) | Per-kind tray notification redesign — accent colors, status-bar icons, MessagingStyle/BigPictureStyle/colorized zap cards, aggregation, Conversations/Bubbles; closes nutzap/onchain/repost/badge parity gaps. | | [2026-06-20-napplet-inter-applet.md](2026-06-20-napplet-inter-applet.md) | NAP-INC / NAP-INTENT inter-applet messaging — deferred; prerequisites (multi-applet hosting, archetype registry, `MESSAGING` capability) not yet built. | From b7754a061fe5c3cbe79b60ade111eeb1cebb6e95 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 19 Sep 2026 02:47:54 +0000 Subject: [PATCH 026/148] feat(cordn): enforce Marmot/cordn independence, and design the UI around it Marmot is frozen. The two protocols do not interoperate, neither is a layer of the other, and the requirement is that either side can walk away without the other noticing. That is a standing constraint, so it is now a test rather than a paragraph: - quartz BindingIsolationTest: mls/ imports neither binding nor Nostr, and cordn/ and marmot/ do not import each other. - commons CordnIndependenceTest: the same for the app layer. Both scan shipped source sets only -- an interop test that drives both profiles through one engine is how we demonstrate they cannot collide, and a fixture is data, not a dependency. Both also assert the scan found real files and real imports, because an architecture test that passes for the wrong reason is worse than not having one. Mutation-checked: adding a Marmot import to a cordn file fails the guard. Writing the first guard found a real leak. mls/group/MlsGroup.kt imported nip01Core.core.toHexKey -- a Nostr import inside an engine whose own README says it "knows nothing about Marmot, Nostr, or cordn". The README only ever grepped for marmot, so the stated invariant was wider than the check. toHexKey() is defined as Hex.encode(this), so the fix is a one-for-one swap to the binding-neutral quartz/utils/Hex with no behaviour change. The UI plan is rewritten around the constraint. The shared-chat-surface option is gone, not deferred: cordn gets its own screens, and the two share only app furniture -- theme, buttons, avatars, QR, media viewers, upload, icons -- never a chatroom model, message view model, feed filter or group screen. The Note / LocalCache adaptation stays rejected on its own merits too: cordn envelopes are unsigned with no relay provenance, and one escaping into relay-bound code is a confidentiality bug, not a rendering bug. The cost is stated plainly rather than hidden: ~2-3k lines of screen code that resembles Marmot's, and chat fixes that land twice. The mitigation is not an abstraction -- it is keeping cordn's screens small enough to hold in one head, which means building what cordn users need rather than porting Marmot's feature set. Stage B adds the third guard, over the Android screens, with the first screen rather than after the fifth.

So edits, deletions and pins are app conventions, not protocol, and the reference client picked numbers for them: 1010 edit, 1011 pin, 5 deletion, plus a client-side system row that is never sent. We follow cordn-web. Being the second implementation of an unspecified convention is how it becomes specified; a third numbering would leave two clients that silently no-op on each other's edits. These differ from Marmot's (1009 edit, no pin, kind-1210 system rows on the wire) and that is fine -- the two protocols do not interoperate and each carries its own table. - CordnMessageKinds: the catalog, with the divergence table in its KDoc. SYSTEM is negative because it is not a wire kind: derived rows cannot disagree with the MLS state they describe, cost no bytes, and cannot be forged by a member who simply sends one. - CordnMessageReferences: inbound parsing and outbound tag building in one file, because they are two halves of one format and splitting them is how a client ends up emitting tags its own parser rejects. A test asserts that round-trip for all five reference kinds. - CordnAnnotationIndex: the fold -- and the reason this is protocol code rather than view-model code, because the authorization rules live in it. The rules, each with a test that fails if it is loosened: reactions are open; edits and deletions are author-only (and a deletion's `k` must match the target's kind -- a mismatch is a mismatch, not a typo to forgive); pins are any-member, matching the reference client and the egalitarian-when-empty admin model of spec/01.md. Two orderings are load-bearing. Deletions resolve before edits, so a late edit cannot resurrect text its author already withdrew. Ties break on the coordinator's cursor, which is the only total order two clients both see (spec/00.md §4) -- without it, two edits in the same second are a coin flip two clients could call differently. The cursor breaks ties and is never an identity, per spec/02.md §7.

d4c61418c2f00de1503e3be5e06ff639abc0a7ce Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 19 Sep 2026 15:50:09 +0000 Subject: [PATCH 028/148] test(cordn): prove the group manager over the real ContextVM transport MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CordnGroupManagerTest drives the manager against a plain Kotlin object. That covers its logic and not one byte of the wire: no gift wrap, no relay, no JSON-RPC framing, no CEP-16 _meta, no stable/ephemeral identity split. Every one of those is a place the feature can be broken while that suite stays green. CordnTransportIntegrationTest runs the same lifecycle -- publish a key package, create, invite, join from the Welcome, send, catch up and read -- over CvmTransport, an in-memory relay pool and the fixture server, with two separate accounts. Encryption is left at its default (REQUIRED) rather than disabled for convenience, because a test that turned it off would be testing a transport we do not ship (§8.6). Three of the four tests assert claims the fake could never check: that no plaintext or gid reaches the relay, that msg_post/msg_fetch_many ride the throwaway key while kp_publish deliberately does not (§8/§8.4), and that a Welcome addressed to Bob is invisible to Alice. Getting there needed three fidelity fixes to the fixtures, each a place where the fake was easier than the truth: - CvmFixtureServer handlers now receive a CvmRequest carrying the signed kind-25910 event. spec/00.md §7 gives cordn no KeyPackage event kind, so the publication payload a kp_take serves back IS that request event; a fixture that could not see it could not model kp_publish at all, and the §9 verification in invite() was therefore never exercised end to end. - welcome_take is addressed, not broadcast. welcome-delivery.md has the coordinator serve a Welcome to the member it names; returning everyone's would let any account join any group -- and would have made the join test pass for the wrong reason. - welcome_store stored its raw arguments, which carry no `at`. The coordinator assigns one, welcome_take reports it, and `consumed` identifies a record by (kp_ref, at) because one last-resort KeyPackage can back several Welcomes. Only a real store-then-fetch round trip notices; every existing test seeded welcomes directly. CordnFixtureCoordinator moves to commonMain alongside its ContextVM siblings so commons can drive it. Mutation-checked: disabling encryption, signing the message path with the account key, and broadcasting welcomes each kill exactly one test.

The load-bearing part is ordering, and each rule has a test that dies without it: - Publish stores the private half *first*. A publish that lands on the coordinator and then fails locally leaves a KeyPackage others can invite us with and we cannot open; storing first makes the failure harmless. - Withdraw tells the coordinator *first*, for the mirror reason: while it still serves the package, we still need the key. - Top-up counts what the coordinator holds, not what we published — kp_take consumes a single-use package, so our count never falls. Last-resort packages do not fill pool slots. - kp_ref is the RFC 9420 KeyPackageRef. Getting it wrong fails silently in the worst way: every take misses and no group ever forms. - A second device publishes its own last-resort package, because kp_list is per account and adopting the other device's key sends every fallback Welcome somewhere this device cannot open. **Registry** (`CordnCoordinatorRegistry` + `CordnSession`), opened through a `CordnCoordinatorScopeFactory` seam so production passes relay-backed transport and encrypted stores while tests pass the fixture. It is idempotent per coordinator under a mutex: a second `CordnGroupManager` would deserialise its own copy of every MlsGroup from the same store and commit against the same epoch, and MLS has no recovery from a forked ratchet tree. It is never merged across coordinators, because a gid is unique only within one (§4). Editing relays reopens the transport but keeps the stores, and `forget` closes the wire without wiping state — removing a coordinator is not purging it. A session restores its own groups and KeyPackages on open rather than trusting the caller to remember. Supporting changes: `CordnTransportHarness` extracted from the Stage A.1 integration test and given a second coordinator (several rules cannot even be stated against one); the fixture coordinator now consumes single-use packages on take, reads the last-resort marker out of the KeyPackage bytes as a real one would, and can refuse a removal. Every rule above was mutation-checked. Three tests were added because a mutation survived: the withdraw ordering (the happy path cannot see it), the last-resort/top-up interaction, and the second-device case. A fourth survivor exposed that the concurrency test never suspended inside the open, so nothing could interleave — the fixture now yields, as production does. Nothing here touches Marmot; the §3.1 isolation guards still pass.

The cipher is an interface for one reason: the KeyStore cannot run in a JVM unit test, and everything below it fails silently. Marmot's equivalent store is welded to the KeyStore and has no unit test at all; this one has sixteen, including that the plaintext never reaches the disk. What they pin down: - Scoped per account AND per coordinator. Two accounts on a device must not read each other's groups, and two coordinators can both serve gid "abc" as unrelated groups (spec/00.md §4) — ignoring either key would have one overwrite the other's ratchet tree. - A gid is caller-chosen, so it is encoded rather than validated. Marmot's store demands hex because a Marmot group id is a hash; a cordn gid is whatever its creator picked and may contain ".." or "/". Base64url accepts every legal gid, keeps the write inside the store directory, and reverses — which is what lets listGroups return the real gid instead of a hash. - Atomic writes. A truncated MlsGroupState is not a stale group but an unreadable one, and it cannot be re-derived from anywhere on the device. - Deleting a group takes its cursor with it, or a later re-join of the same gid resumes from a cursor for a group it is no longer in. The Android cipher serialises its calls. `KeyStoreEncryption` keeps one `Cipher` in a field, and `init` + `doFinal` is not atomic while the stores run on Dispatchers.IO — two groups saving at once would corrupt one of them. The lock is in the cordn wrapper; the shared class Marmot and account storage depend on was not touched. **Sync loop.** `CordnSyncLoop` over a `CordnSyncSource` seam that `CordnGroupManager` implements: catch_up drains history, then a subscribe is held open and re-opened when it closes. Wrapping two calls would be pointless if the happy path were the story, but three things separate an unattended loop from a call, and each has a test that dies without it: - A failure must not end the loop. A coordinator down for a minute is ordinary; an exception that escapes stops syncing for the session and looks exactly like a quiet group. Every attempt is caught, recorded on CoordinatorHealth, and retried with a backoff that resets on success — without the reset, one bad stretch pins the loop at its cap forever. - An account with no groups must not spin. Both calls return immediately when the manager holds nothing, so the obvious while(true) burns a core on every new account, silently. The loop parks on gids instead. - A group joined mid-subscription must not wait. A subscription is opened for a fixed set of gids; a change to the set cancels and re-opens rather than leaving the new room empty until the stream times out. A closed stream is a re-subscribe, not a failure — counting a normal timeout as an error would put a healthy loop into permanent backoff. start() is idempotent, because two loops on one session would double every message. `CordnGroupManager` gains `: CordnSyncSource` and three `override`s; no behaviour changed. The seam exists so the loop can be tested for what it actually does — provoking a network failure on a schedule through a real transport would be the flakiest thing in the suite. Every rule above was mutation-checked: seven mutations on the loop, five on the stores, all killed. One store mutation survived and was informative — the ".tmp" exclusion in the key-package listing was unreachable, because "." is not in the base64url alphabet, so the encoding already rejects it. The dead branch is gone and its test now guards the encoding, which is the real mechanism and a regression worth catching. Nothing here touches Marmot; the §3.1 isolation guards still pass. Not yet wired: nothing constructs a FileBackedCordnScopeFactory, because its link factory needs Amethyst's relay pool and account signers. That is Stage B's first step and it is one function.

Three rules, each with a test: - **Keyed by envelope id, never by cursor.** spec/02.md §7 makes the envelope id the identity and the cursor a delivery primitive. A catch_up after a restart re-walks the stream and returns messages we already hold — with a NEW cursor, because a cursor is coordinator-local. Keying on it would double the room every time it recovers, which is exactly when it must not. - **Ordered by the cursor, not by the sender's clock.** This reverses what I first wrote, and a surviving mutation is what prompted the rethink: both ordering tests had the cursor and created_at agreeing, so neither could tell the two designs apart. Forcing them to disagree makes the answer clear — created_at is a claim the sender makes about their own device, so sorting on it lets one wrong clock scatter a member's messages through the room and lets a sender pin a message to the top of history by backdating it. The cursor has neither problem and is the order every member already agrees on. It does trust the coordinator to order the stream, which §4 makes it the sole authority for anyway; MLS still authenticates what was said and by whom. - **Annotations fold, they do not render.** A reaction is not a line in the transcript, and must not become the room's inbox preview. The room carries one `Note` — `inboxRow()` — so the unified Messages list can find it through `Note.inGatherers`, the way it finds a Marmot room. One Note per room, not per message: nothing here puts a cordn message into LocalCache, where it would become searchable, notifiable and indistinguishable from an event that was actually published somewhere. Marmot uses the same trick only for an empty group; for cordn it is the whole mechanism. **Runtime** (`amethyst/model/cordn/`): `NostrClientCvmRelayPool` adapts Amethyst's relay client to ContextVM's `CvmRelayPool`, and `CordnRuntime` assembles registry + encrypted stores + sync loops per account — the one function Stage A left open, now closed. Two details worth naming. The coordinator's own relays are used, not the account's: a coordinator has no address beyond its pubkey (§8.5), so the account's outbox would both miss it and tell relays that have no business knowing that this account talks to it. And the ephemeral signer is created per runtime and never persisted — §8 splits the identity a coordinator sees, and a "session" key reused across launches is just a second account key with worse ergonomics. Also adds `ChatFeedType.CORDN` and hoists `gid` onto `CordnGroupManager.Delivery`, which every variant already had.

One row per room, carried by the room's own Note through `Note.inGatherers` — the hook Marmot uses for an empty group, used here as the whole mechanism. Nothing puts a cordn message into LocalCache. That is the difference worth naming: Marmot/Buzz/Concord rows exist because their messages become Notes, and doing the same here would make private MLS payloads searchable, notifiable, and indistinguishable from events actually published to a relay. So the row renderer takes the room rather than the Note and reads the live data off it — including the *edited* text, since showing the original in the inbox while the room shows the edit reads as a sync bug. **In the + menu.** A cordn entry beside Marmot and Concord, with its con stated where the choice is made rather than discovered afterwards: the coordinator learns who is in the group and when they talk, even though it can never read a word. That is what the whole §8 exposure surface was for, and this is the first place it can be said. **On screen.** A minimal chat screen (ordered messages, sender, send a kind-9) and a group info screen carrying metadata, coordinator, gid, epoch, members and admins — plus `CordnExposureCard`, whose real home this is. The link screen shows the same disclosure before joining, when it is a decision; this shows it after, when it is a fact worth being able to check. Two small honesty details. An empty admin set renders as "everyone is equal, permanently" rather than "0", because spec/01.md makes it exactly that and a zero reads as a group waiting to be configured. And a deleted message renders as deleted rather than as its original text, which would defeat the deletion. **Guard.** `CordnScreenIndependenceTest` over `chats/cordnGroup/` ⊥ `chats/marmotGroup/`, the third of the three §3.1 asks for — added with the first screen rather than after the fifth. Writing it turned up a real bug in the guard that already shipped. `CordnIndependenceTest` matched forbidden imports with `\bmarmot\b`, and that regex **cannot match the imports that matter**: in `…model.marmotGroups.MarmotGroupChatroom` a word character follows `marmot` both times, so `\b` fails and the guard waves through exactly the dependency it exists to stop. It has been green since it landed because nothing violated the rule, not because it was checking. Found by reading the regex while trying to prove the new guard bites. Both guards now match on a plain substring, which is safe because only `import` lines are scanned — the word "marmot" in an import IS a Marmot dependency. Both also gained a meta-test that asserts the matcher flags a real Marmot import, so a guard that can never fire stops being indistinguishable from a codebase that never violates the rule. (`BindingIsolationTest` in quartz was never affected: it matches package prefixes with `startsWith`.) Proving it bites needed a second discovery: spotless/ktlint runs as part of the Gradle test build and strips unused imports, so an import-only mutation deletes itself before the test ever reads the file — every such attempt "passes" no matter how broken the guard is. With a mutation the formatter has to keep (an import plus a function that uses it) the new guard fails exactly as it should. Also wires `CordnRuntime` into `Account` (built there because it needs the account's scope, like `marmotManager`) and adds the Messages settings toggle. Reuses the existing `Dns` codepoint rather than adding an icon, so the subset font does not need regenerating.

This is the screen behind it, which is Stage C.13 of amethyst/plans/2026-09-19-cordn-ui.md arriving early because an entry point with nothing behind it is worse than no entry point. **Creating.** Pick the coordinator (an already-open one, or a pubkey — hex or npub — plus the relays it answers on), name the group, create. The coordinator is the first field rather than a setting, because `spec/00.md` §4 makes it half the group's identity and unchangeable after: a `gid` means nothing outside the coordinator that issued it. The exposure card sits under the choice, counting this group against however many that coordinator already serves for this account, since the disclosure is about what one coordinator can correlate. Creating sends nothing. `CordnRuntime.createGroup` is local MLS work; the coordinator hears about the group when the first Commit or message is posted. So it works against a coordinator that is down, and a group of one has told the coordinator nothing at all. The `gid` is a random UUID, which is what cordn's own client uses. Inviting is deliberately absent. `CordnGroupManager.invite` works, but its user-facing half — key-package discovery, share links, join requests — is Stage C. A member picker that could only offer accounts that happen to have published a KeyPackage to this exact coordinator would promise more than it can do. **Rooms that know their own name.** `CordnGroupChatroom` carried `name`, `description`, `adminPubkeys`, `members` and `epoch` as MutableStateFlows that nothing ever wrote, so the group info screen B.9 added showed a blank name, zero members and epoch 0 for every group, always. They are now private, exposed read-only, and written by `refreshFrom(MlsGroup)`. Derived, never stored, and re-read after every delivery rather than only on an EpochAdvanced: a Commit can rename a group or remove a member and arrives as an ordinary ingestion, so a cached copy goes stale in exactly the cases that matter. Members come from `CordnCredential.memberIdentities`, not `MlsGroup.memberIdentityHex` — the latter hex-encodes credential bytes, and a cordn credential already is hex, so it would report 128 characters of hex-of-hex. Five tests, two of them mutation-checked: emptying the member read and letting a name survive a group swap each fail a named test.

It then did `groups[gid] = group` unconditionally. Together those mean a second drain — a relaunch, a retry, a sync loop running twice — reinstalls the Welcome-epoch group over the live one. MLS does not recover: every message after the rolled-back epoch stops decrypting, silently and permanently. Proved before fixing, as `a second drain does not roll a live group back to its welcome epoch`: Bob joins at epoch 1, applies Carol's Commit to reach 2, drains again, and lands back at 1. **The split.** Opening a Welcome and accepting it are now different acts. `pendingWelcomes` opens each one and reports what is inside — gid, group metadata, who is already in it, epoch — without joining anything, which is the only way a user can be asked about an invitation at all: a Welcome is opaque until processed. `accept` installs and retires it, refusing a gid already held rather than replacing it. `decline` retires without joining. `joinPendingWelcomes` stays as the unattended path for amy and tests, now implemented on top. Three kinds of Welcome are handled differently, and the difference matters: - no private half → skipped, left on the coordinator. It belongs to another device of this account and retiring it destroys their only copy. - already a member → skipped *and* retired. That is the stale record a dropped connection between accepting and acknowledging leaves behind, and letting it pile up is what made the second drain destructive. - opened → offered as a decision. `OpenedWelcome.members` is who is in the group, not who invited you. A Welcome carries the ratchet tree, not the identity of whoever signed the Commit that created it, so "X invited you" would be a guess dressed as a fact — and in a group of three, usually the wrong one. Retiring rides the next `welcome_take` because that is the only shape the call has. One is sent immediately so the common case is prompt; a failure parks it and the next `pendingWelcomes` flushes it, because failing to retire must never fail the join it follows. Six new tests. Three mutations checked: dropping accept's retire, dropping the already-a-member guard, and retiring another device's welcome each fail the one test that names them.

1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stage C cannot be built without this, and Stage B was quietly broken by its absence: `CordnCoordinatorRegistry.coordinators` was in-memory only and nothing called `CordnRuntime.start`, so a coordinator entered once was gone at the next launch. The MLS state stayed on disk, but a `gid` with no coordinator is not a group anyone can open, and nothing else on the device knows which coordinator serves it — so every cordn room disappeared and no screen could get it back. `CordnCoordinatorStore` is a third store beside the group and key-package ones, and is scoped differently on purpose: those are per (account, coordinator), because a `gid` and a `kp_ref` only mean anything relative to one coordinator. This is the list OF them, so it belongs to the account and sits in `/cordn//coordinators`, one directory above them. Put inside a coordinator's own directory, removing that coordinator would delete the record of every other one — there is a test asserting the two are siblings rather than nested. Encrypted at rest like the rest. Not because it is key material, but because which coordinators an account uses is the sharpest metadata cordn produces — it is precisely what §8 spends its length keeping any one coordinator from learning about the others. TLS-framed rather than line-delimited, for the reason `KeyPackageBundleCodec` gives: a label is free text someone typed, so whatever separator a delimited format picked is one they can put in it. Tested with tabs, newlines and a NUL in a label. An entry whose `origin` this build does not know, or whose relays all fail to normalise, is dropped rather than throwing, and an undecodable file returns an empty list — losing the coordinators costs a re-entry, while throwing here would fail login. `restore()` runs at login in its own launch rather than inside Marmot's restore block: the two protocols are independent by design (§3.1), and a cordn coordinator that is down must not delay Marmot's startup or the reverse.

Join opens the room; decline retires it. **Not "X invited you".** A Welcome carries the ratchet tree, not the identity of whoever signed the Commit that produced it, so the card says who is already in the group and stops there. In a group of three, naming an inviter would usually be wrong, and it would be wrong in a way nobody could check. **No badge, and no background poll.** Finding out whether anyone invited you means asking each coordinator, and every call to a coordinator is metadata (§8). A live count would tell each of them how often this account opens the app, forever, to save a tap. So the fetch happens when someone opens the screen, and the screen says that is what it does. Three outcomes are kept distinct because they mean different things and collapsing them lies to the user: - an invitation, offered as a decision; - a coordinator that did not answer, on its own row — "we could not ask" and "there is nothing for you" look identical on screen and are opposites; - a Welcome left for another device of this account, shown rather than hidden, because otherwise the invitation a friend swears they sent simply does not exist here. Declining says up front that it is permanent. A retired Welcome is gone from the coordinator and the KeyPackage it was addressed to has been spent; getting back in means being invited again. That is worth knowing before the tap, not after. Reachable from the `+` flow, under the protocol cards: being invited is the other half of "start a conversation", and it does not belong in settings. `pendingWelcomes`/`joinPendingWelcomes` now take a suspending `bundleFor`, so a caller can hand over `CordnKeyPackages::bundleFor` directly instead of eagerly loading and decoding every bundle in the pool on each check.

The KeyPackage has to be published first because there is nowhere else to put one — `spec/00.md` §4.2 gives cordn no KeyPackage event kind, so the coordinator is the only place an inviter can find it. That is also why publishing happens here rather than quietly at login (§8.4): this is the one moment where it is unambiguously what the user asked for, since they are asking strangers to add them. The screen says so above the button, not after it. **Answering.** The group info screen lists who is waiting, with Add and Dismiss. Accepting takes the KeyPackage the request named — not just any of that account's — because taking a different one spends a package they meant for someone else; `invite` gained an optional `keyPackageRef` for that, and still verifies the publication payload binds it to the right account. The request is retired only after the invite lands: a request dropped before the Welcome exists is a person who asked, was told nothing, and has no way to ask again without a fresh link. **Any member can add someone, and the screen says so.** cordn's `admin_pubkeys` is presentation metadata — `spec/01.md` §5.3, and `CordnGroupPolicy` has no authorization hook because neither the spec nor the reference coordinator restricts who may commit. Gating this section on an admin check would invent a boundary the protocol does not have, and imply to everyone else that it protects them. **The stage's verification.** `CordnJoinRequestTest` drives link → request → accept → first message in one test, with two accounts over one coordinator's storage (`FakeCoordinator.viewAs`, since the caller is fixed at construction for Welcome routing). Two more cover declining and the named-KeyPackage rule. Both load-bearing lines are mutation-checked: ignoring the named ref, and retiring a request before the invite, each fail a named test. The fake's join-request methods were stubs returning nothing, so nothing above them had ever been exercised; they now store and retire for real.

Group info now shows the group's `cordn1…` ref as selectable text and as a QR, with a copy button. The ref is built from the live MLS group via `shareRef`, so it carries the coordinator that actually serves the group rather than whatever the screen was navigated with — and it includes that coordinator's relays, without which a recipient has a pubkey they cannot reach. The line under it says what a link is worth: anyone holding one can ask to join, and a member still has to add them. The link screen gained a Scan button beside Paste. A scanned ref goes through exactly the same `CordnLinkInspection.of` as a pasted one, so scanning cannot take a shortcut typing does not have — the disclosure, the coordinator check and the exposure card are the same either way. Both reuse the app's existing QR components rather than adding any: they are common app components, not Marmot's, so the §3.1 isolation guard is untouched and still passing.

It had. The card was on the info screen with `linkedGroupCount = 1`, `joinedFromShareLink = false` and `publishedKeyPackage = true` written as literals — present, so the requirement looked met, and constant, so it told nobody anything. It now comes from `exposure(gid)`, which was already there and unused. Two of the three fields needed work to be answerable at all: **Did we ask to join?** §8.1 — a join request names the asker's real npub against a specific group, so once it has happened the coordinator can tie this account to this group permanently. That fact is now persisted next to the cursor, written at the moment `requestToJoin` is called and surviving the relaunch. It is recorded whether or not anyone ever answers, because the exposure is the asking, not the joining: recording it only on success would understate it in precisely the case where nothing else on screen mentions the request at all. **Do we have a KeyPackage published here?** The manager only knew what it had published itself, this run, so after a relaunch it reported "no" about a KeyPackage sitting on the coordinator right now. `CordnKeyPackages` answers it from the store, and `CordnSession.exposure` is the first place that holds both halves. It errs toward overstating by one — a stored private half whose publish failed counts — which is the direction a privacy surface should err in. The general rule underneath: a coordinator does not forget at app restart, so an exposure surface that resets to a cheerful default at launch is not a softer version of the truth, it is the wrong answer. Three tests, all three mutation-checked: reading the flag as `false`, reading published state from the session flow instead of the store, and the restart case each fail a named test.

Until now the only way to add a coordinator was to type it into the create-group form, and `CoordinatorHealth` had been populated since Stage A with nothing anywhere to display it. **Remove and purge are two decisions, and only one is reversible.** Removing closes the session and leaves the MLS state on disk, so re-adding brings the groups back — `CordnCoordinatorRegistry.forget` already said this in its KDoc and left the purge half to "whoever owns the stores", which is the runtime. Purging deletes the ratchet trees, the cursors and the KeyPackage private halves, after which those groups can only be re-entered by a fresh invitation, because MLS state cannot be rebuilt from anywhere else. The confirmation spells that out, since "delete" usually means the reversible one. Neither tells the coordinator anything, and the dialog says so. It keeps what it already had; purging is about this device, and implying otherwise would sell a deletion nobody can perform. **Health is observed, never polled.** `CoordinatorHealth` records what the calls the app was making anyway saw, because a poll is a call and every call is metadata (§8). So "nothing asked of it yet" is a distinct state from "not answering" and reads differently — the first is not a problem. **Server info is a claim, labelled as one.** `initialize` is the MCP handshake, not a twelfth coordinator tool, so it stays off `ICoordinator` — that interface's KDoc is explicit that it is "the eleven coordinator tools" and adds nothing to them. It rides on `CordnCoordinatorLink` instead, where the transport lives, defaulting to null so a fixture need not invent a handshake it never performed. It is fetched on a tap, not at open: a coordinator that only hears from us when we have something to say learns less than one greeted at every launch. And a name and version are strings the server chose — the line under them says the pubkey is the only identity (§8.5), because a name on a settings screen otherwise reads as verified. Purge has to delete the coordinator's own directory and nothing above it: two coordinators routinely hold state for the same `gid` as unrelated groups, so a level too high takes both. Four tests cover that, the account-level coordinator list surviving a purge, the in-memory room list dropping by coordinator rather than by gid (mutation-checked), and the join-request marker's lifetime.

There is no relay to fall back on — the coordinator is the only place an inviter can find one, so an account with none published cannot be added to a group and nothing anywhere says why. Marmot's equivalent is invisible because its packages live on relays; here the publish is a call to one named party, which makes it a decision rather than housekeeping. **Never the first package, always the ones after it.** Publishing is attributable under the account key (§8.4): it tells that coordinator this account exists and is invitable, permanently, whether or not anyone ever invites anyone. That is not something to do on someone's behalf at login. But once a package *is* published there, the coordinator already knows, and letting the pool drain has a cost with no matching benefit — `kp_take` consumes a single-use package, so the pool falls as people invite you, and an empty pool fails the next invitation for a reason the inviter sees and the invitee never does. So `maintainKeyPackages` tops up only where `hasPublished()` is already true, detached and swallowing failures, because upkeep must not stop a coordinator's groups from syncing. The screen states the rule where the person it applies to can read it. **Two truths, shown separately.** The coordinator's listing says what an inviter can take; the local store says whether the resulting Welcome can be opened. A package in the first without the second belongs to another device — or to an install that is gone, in which case anyone using it sends a Welcome nobody will ever read. The screen surfaces those specifically, with a withdraw button, instead of folding them into a count. `listPublished` asks the coordinator rather than reporting what we think we sent, for the same reason: our record drifts upward from reality the moment anyone invites us. Two tests, one mutation-checked (dropping the this-account filter).

The asymmetry this closes was worth naming: the chat screen has rendered edits, deletions and reaction folds since the protocol work landed, because `CordnAnnotationIndex` came with it — but the composer only ever sent kind 9. cordn could read a conversation it could not take part in. The tags and kinds come from `CordnMessageReferences.outbound`, which already existed with round-trip tests. `CordnGroupManager.post` is the one new seam, and it earns its place by refusing two sends: **Edits and deletions are author-only, and the call says so.** The fold enforces that when annotations land, so editing someone else's message would otherwise appear to work — sent, stored by the coordinator, delivered, and then silently dropped by every client including the sender's. Throwing at the call is the difference between a bug someone can report and one nobody can see. Reactions and pins get no such check, because §5.1 makes a reaction anyone's and a pin any member's; adding one uniformly would invent a rule cordn does not have. The action sheet hides edit and delete on other people's messages for the same reason, stated where it stops being a surprise. **Pins get a ribbon, not just a flag.** A pin is a claim about a message's importance rather than a message, so pinned items sit above the conversation — leaving them only in place means the thing someone pinned scrolls away exactly like everything else. A pinned message that was since deleted renders as deleted there too: a pin must not outlive the withdrawal of what it points at. Replying carries the target's own tags into `Target`, so replying to a reply keeps the original thread root instead of starting a new thread at the reply. Reaction counts are set sizes from the fold, so a double-tap or a re-sync counts once. Six tests on the send side, covering both refusals and the three kinds that are deliberately not refused.

It goes through the same store and the same cipher as the conversation, because the alternative makes the composer the weakest point in an end-to-end encrypted feature: the plaintext of a message that was one tap from being sealed, sitting in the clear. Clearing a draft deletes the file rather than blanking it, so the old plaintext is not left in whatever the filesystem still holds. Tested both ways. **Unread is counted on the coordinator's cursor, not on anyone's clock.** Same reason the room is ordered on it (`spec/00.md` §4): a sender's `created_at` is a claim, and one wrong clock would otherwise leave a room permanently unread or silently swallow new messages. Two things deliberately do not count, each mutation-checked: - this account's own messages, which echo back from the coordinator with a fresh cursor exactly like anyone else's — counting them would badge every room the moment its owner spoke in it; - annotations, because a thumbs-up on something already read is not a new message, and badging for one trains people to ignore the badge. Read positions are restored with the rooms at login rather than when a room is opened: an inbox that shows every room as unread until it is visited is worse than one with no unread state at all. The draft and read position are written on leaving the room — saving per keystroke would rewrite an encrypted file per character, and process death loses no more than that. The inbox row's `hasNewMessages = false` placeholder, and its comment saying a read marker was its own piece of work, are both gone.

Amethyst's rich-text renderer is built on `Note`, and a `Note` comes from `LocalCache` — which is precisely where a cordn message may never go, because that would make private MLS payloads searchable and notifiable alongside things actually published to a relay. So cordn gets a small segmenter of its own over the envelope's own content. The distinction that makes this safe is worth stating plainly: the rule is about what goes *in*. Resolving a mentioned pubkey to a display name reads a profile — public relay data the cache already holds — and puts no part of the conversation into it. `CordnMentions.segment` splits a message into text and mention runs, and a test asserts that concatenating every segment's original text reproduces the input exactly. That invariant is the point: a renderer that dropped a segment would silently eat part of someone's message, which is worse than not rendering mentions at all. Two cases it protects — a `nostr:` URI the regex matches but bech32 cannot decode, and punctuation immediately after a mention — each have a test. `nostr:` is required, unlike NIP-19's looser scan. A bare `npub1…` mid-sentence is as likely to be someone quoting a key as mentioning a person, and turning it into a name changes what they wrote. URLs, hashtags and embedded events are deliberately out. Each of them renders as something, and something that renders is something that can leak — an auto-loaded preview would fetch a URL the moment a private message arrived, telling its host that a specific person opened a specific message. That belongs with the media work and its decisions, not smuggled in behind mentions.

A test feeds a cordn blob to MIP-04 and asserts it fails, which is the correct outcome for two incompatible formats sharing ChaCha20-Poly1305. **The nonce carries more weight here, and that is written down.** Because the key is the exporter output as-is, every file in an epoch is encrypted under the same 32 bytes and the nonce is the only thing separating two keystreams. MIP-04 can tolerate a weak nonce far better — its per-file HKDF means a repeat only collides within one file's key. So `encrypt` draws a fresh random 96-bit nonce with no deterministic option, and a test encrypts the same file 64 times and asserts 64 distinct nonces. Making it deterministic fails that test. **What each party sees was the actual design work.** The blob host gets opaque bytes declared `application/octet-stream`, with no `alt` text and no content warning — both are plaintext on a Blossom upload, and an alt string describing a private photo is that photo's caption handed to a server meant to see nothing. The `/media` endpoint is never used: it asks the server to re-encode, which destroys ciphertext, so an account with "optimize uploads" on would otherwise break every attachment silently. The whole `imeta` descriptor — URL, type, filename, hash, nonce — rides inside the MLS envelope, so the coordinator sees none of it either. Two hashes on purpose: Blossom names a blob by the SHA-256 of what it stores, the ciphertext; the descriptor carries the hash of the plaintext. Neither derives from the other, and the plaintext hash never reaches the host. **Attachments are fetched on a tap, never automatically.** Fetching tells the blob host that a specific person opened a specific message at a specific time. Auto-loading would do that for every message that scrolls past — the exact leak an end-to-end encrypted group exists to avoid. Ten tests on the codec and the tag, two mutation-checked: a deterministic nonce, and dropping the plaintext hash from both the AAD and the post-decrypt check.

A voice note is a file, so it goes through exactly the path the previous commit built: the same codec, the same opaque Blossom upload, the same `imeta` descriptor sealed inside the MLS envelope. Amethyst's existing `VoiceMessageRecorder` does the recording. Two things are cordn-specific and both are about plaintext on disk: **The recording is deleted after it is sent.** The recorder writes plaintext audio to `cacheDir`. Leaving it there would keep an unencrypted copy of a message that is end-to-end encrypted everywhere else — the one lasting copy should be the ciphertext on the blob host. Deleted in a `finally`, so a failed upload does not leave one behind either. **Playback writes a scratch file and deletes it on dispose.** `MediaPlayer` cannot take a byte array, so decrypted audio has to touch disk to be played at all. It goes to a file the composable owns and removes when it leaves composition, rather than anywhere durable. The microphone permission is requested on the first press, not when the room opens: opening a chat is not consent to use the microphone, and a dialog that appears before anyone reached for it is one people learn to dismiss. A press too short to be a message returns null from the recorder and is dropped silently, because an accidental tap should not send a zero-second voice note to a group.

Two findings settle it, and neither is a preference: **Portability was never available.** The valuable content of any cordn backup is MLS group state, and that is an engine's internal serialization, not a wire format — which is the same reasoning §4.6 uses to rule out multi-device. Theirs is ts-mls's `ClientState`, ours is `MlsGroupState`, and neither reads the other whatever container wraps it. A byte-compatible file would buy a restore that cannot restore. (Their client also sits outside the two MIT packages, and the spec prose is unlicensed.) **There was nothing to fold into.** The plan says "Amethyst has account backup already", and it does — of *keys*. A relay-backed account rebuilds itself from an nsec; a cordn group does not, because the key alone restores nothing. So this is a new thing rather than an extension of an old one, and the screen opens by saying exactly that. **Restoring replaces a device. It is not a merge and not sync.** An MLS state export is a cloneable identity: two devices holding one group's state and both committing fork the ratchet tree, after which messages silently stop decrypting for somebody with nothing on screen to explain it. `import` wipes this device's cordn state before writing the archive's, refuses an archive from a different account, and the confirmation dialog says what happens if someone restores onto a second phone while the first is live. Format: scrypt at NIP-49's default cost, ChaCha20-Poly1305, a versioned header. Nine tests, two mutation-checked — an absent cursor becoming a real zero position, which would make a restored room replay its whole history, and the "no key material in the clear" check. One honest note in the KDoc. The header is passed as the AEAD's associated data, and a mutation removing that survives the suite. That is expected, not a gap: every header field today either feeds the key derivation, feeds the cipher, or is checked outright, so an edit already fails. The AAD is there for the first header field that does none of those, which is when forgetting it would be the easy mistake. The test that used to claim otherwise now states the real reason.

Open question 1 — shipping before a licensed coordinator exists to test against — is now the only thing between this plan and users, and is noted as such.

The missing one is `msg_sub_many` — live delivery — so every cordn test reached the coordinator through `msg_fetch_many` and the half the sync loop actually lives in had no coverage at all. It is the one tool whose answer is not its result. A real coordinator holds the call open and pushes each message as a CEP-41 stream fragment, which `CoordinatorClient` reassembles through `onStreamFragment`; the CEP-41 machinery has its own 26 tests, and nothing had ever driven cordn over it. The fixture needed a seam, because a handler returns one message and that is exactly what a subscription is not: `emitStream` hands frames back to the transport, wired in `CordnTransportHarness` where both halves are in scope. Null by default, so a fixture that only drives catch-up is unchanged. Two tests: a subscription delivers a group's own stream and nobody else's, and a second member reads what was said live with the sender MLS-authenticated. Mutation-checked by making the fixture send no chunks — both fail. Also fixes a landmine in the other fake. `FakeCoordinator.publishKeyPackage` returned a receipt and stored nothing, so `kp_list` never saw a published package — proved with a throwaway test before touching it. Nothing breaks today only because `topUp`'s tests use the fixture instead; the first person to test the pool against this fake would have got an infinite publish loop with no visible cause. The publication event stays null there, and that is structural rather than lazy: `ICoordinator.publishKeyPackage` carries a ref and bytes, while the §7 publication payload IS the transport's request event — which a fake sitting directly on the interface never sees. So this fake can say a package exists but cannot make it takeable, `takeKeyPackage` skips the ones it cannot verify, and the KDoc says to seed one. `CordnFixtureCoordinator`, which handles the request itself, has the event and does not have this limit.

Every rule in it was a sentence in a commit message and none of them was executable, which is the combination that lets a rule quietly stop being true. Six tests, and all five mutations are killed by the test that names them: publishing the first KeyPackage on someone's behalf, dropping the upkeep entirely, importing without wiping first, accepting another account's archive, and swallowing an unreachable coordinator into "nothing waiting". Reaching the class at all needed one seam. `cipher` was always injectable because the Android KeyStore cannot run in a JVM test; `links` is the same idea for the transport, since production opens a real ContextVM connection per coordinator. Both still default to the real thing, and the ephemeral signer stays inside the default — §8's identity split is not something a caller should be able to widen. **The tests were wrong twice before they were right, and the reason is worth recording.** `maintainKeyPackages` reads the KeyPackage store, which hops to `Dispatchers.IO`. A `TestScope` cannot reach across that: `advanceUntilIdle` does not drain `backgroundScope`, `runTest` elides `delay` into virtual time, and sharing the test scheduler only made the sync loop — which by design never returns — advance forever. The suite looked green the whole time, because an assertion that something did NOT happen passes trivially when the work has not run yet. Verified by mutation: removing the pool guard did not fail the test that exists to catch it. So these run on real dispatchers with a bounded poll for the positive cases and a generous settle for the negative one, which is the honest shape for observing work on another dispatcher. Confirmed stable over four consecutive clean runs before being committed.

Two of the three were untestable where they sat, which is most of why. **The relay pool and the link factory move to commons.** `amy` needs the same ContextVM transport the Android app builds, and Rule 5 of the CLI's contract says extract before adding — so `NostrClientCvmRelayPool` and `CordnRuntime.realLinks` are now `commons`' `NostrClientCvmRelayPool` and `CordnLinks.over`. Neither had an Android dependency; they were in `amethyst/` because that is where the first caller was. Worth stating why the factory is shared rather than copied per front end: everything it assembles is a protocol decision — which signer signs which call, that gift wrapping stays REQUIRED, that `initialize` is not performed at open — and a second copy is a second place those can drift apart. `CordnCoordinatorLink`/`…Factory` move from jvmAndroid to commonMain with them. They were only there because `FileBackedCordnScopeFactory` shares the file, and nothing about a link is JVM-bound. `CordnBlobCipher` moves for the same reason. **`KeyedCordnBlobCipher`**, new: ChaCha20-Poly1305 under a caller-supplied key, for the platforms with no OS key store to hide one in — the desktop app and `amy`. Android keeps its KeyStore cipher. The nonce is random per blob and the KDoc says why that is the parameter to be careful about: one key covers every blob, and a repeat leaks the XOR of two `MlsGroupState` serialisations, which is epoch secrets. **`CordnBlobUpload`**, new: everything a blob host is told about a cordn attachment, as a value instead of seven literal arguments. This is the one with a real reason beyond testability. Each of those arguments is a privacy decision, and every one of them fails *silently* if it regresses — the upload still succeeds, the group still sees the file, and the only difference is what a server learned. There is no downstream check that would notice. `CordnMediaService` now computes the descriptor and forwards it, so the decisions have one home and can be asserted. 28 tests. What they pin, and what killing each mutation proved: - the REQ goes to the coordinator's relays and matches on the recipient `p` tag, not on `authors` — a gift-wrapped response is signed by a one-time key, so an `authors` filter matches nothing and the call simply times out - a response arriving with `isLive=false` is still delivered; kind 25910 is ephemeral, so branching on it would drop the answer - closing a subscription unsubscribes that id and no other - the blob host gets `sha256(ciphertext)`, `application/octet-stream`, a hex filename, no alt text, no content warning, and `/upload` rather than `/media` - `initialize` claims survive the trip, and each way a server can decline to make one leaves a null — including JSON `null`, which `jsonPrimitive.content` renders as the four-character string "null" and would otherwise put a coordinator called "null" on a settings screen One mutation survived twice and is worth recording. Removing the `require(bytes.size > NONCE_LENGTH)` from `decrypt` changed no outcome: a short blob already throws, either from the AEAD's own tag-length check or from slicing a 12-byte nonce out of a shorter array, and both are `IllegalArgumentException`. So the guard buys no failure — it buys the reason. The test now asserts the message, because that is the only thing there is to assert: "fromIndex(12) > toIndex(0)" from inside a `copyOfRange` reads as a bug in Amethyst, while naming the size points at the file.

Enough to run the whole lifecycle from a shell script, which is what a second implementation is for. `cli/tests/cordn/tier-b.sh` is that script. Read the header of that file before running it. The reference coordinator is unlicensed (interop plan §7), so nothing here pulls it, no build or CI task references it, and it stays a diagnostic you choose to run rather than part of the test process. Running it at all was a maintainer's explicit decision; §7.1 records what it found, which is the argument for having made it. **The verbs.** Three shapes worth naming, because they are not stylistic: - Every live verb takes `--coordinator`, and it is part of a group's address rather than a convenience. A `gid` is unique only within one coordinator (`spec/00.md` §4), so the wrong one is not a near miss — it is an answer about a different group. Omitting it works only while exactly one is remembered, and `--gid` follows the same rule. - `fetch` is explicit because a CLI invocation is a process and cannot hold a subscription. The cursor on disk is the entire continuity mechanism between runs — which is what `spec/02.md` §7 means by calling a cursor a delivery primitive, doing double duty here. - `send --reply-to ID` demands `--to-author PK` beside it. Not an awkward flag: an annotation's tags name the target's author and kind, and amy keeps no message store (cursors and MLS state persist, decrypted messages deliberately do not), so the caller supplies what it read from `fetch`. `NostrClientCvmRelayPool` and the link factory moved to commons in the previous commit for this; `KeyedCordnBlobCipher` is what encrypts the CLI's blobs, and `DataDir.cordnBlobKeyFile` says plainly what a key stored beside its ciphertext does and does not buy. **Finding 1, fixed here: our CEP-4 gift wraps were invisible to any real ContextVM server.** `CvmGiftWrap.wrap` set `created_at` to NIP-59's randomized timestamp — the real time minus up to two days. The reference server subscribes with `since = now` when it connects, the obvious filter for a live request stream, and relays honour `since`. So every request we have ever sent to a real coordinator was dropped **by the relay**, before the server saw it. The symptom is a 20-second timeout with nothing in any log, because from the other side nothing happened. NIP-59 is right in its own context: a gift-wrapped DM is stored and fetched later, so its timestamp would reveal when a conversation happened. A ContextVM wrap carries an RPC request to a peer listening right now, and the shift protects nothing — CEP-4 puts the recipient in a visible `p` tag, delivery is real time, and kind 21059 is ephemeral so no relay keeps it to be read later. It hid from an observer a fact that same observer reads off the socket, at the cost of the request never arriving. Why nothing caught it: our fixture server reads whatever is addressed to it with no `since` filter, and so does every test double. A backdated wrap is indistinguishable from a fresh one unless the other end filters on time, and only a real server does. There was a test asserting the *broken* behaviour — `CVM-4-14`, "the wrap timestamp is shifted and must not be used for ordering" — and it passed for the whole life of the transport. A test that pins what the code does is not evidence about what the protocol needs. It now asserts the send time. **Finding 2, recorded here, fixed in the next commit: self-echo bookkeeping does not survive a process boundary.** With delivery working, a sender's own traffic comes back as `undecryptable` — its Commit sealed under an epoch key it has since left, its message from a ratchet generation already consumed. `GroupInbox` holds that bookkeeping in memory while the cursor beside it is persisted. amy hits it every run; the Android app hits it whenever the OS kills it between sending and syncing. The harness asserts the fixed behaviour and currently fails on it, which is the honest state of the tree for one commit. What Tier B did not find is as informative: both bugs are transport and bookkeeping. Nothing in the crypto surface moved — the MLS engine, the seal, the envelopes and the group refs were already verified against ts-mls and against cordn's own wire contracts, and a live counterparty found nothing wrong with any of them.

The symptom is a 20-second timeout with nothing in any log, because from the +server's side nothing happened. + +Why no test caught it: our fixture server (Tier C) reads whatever is addressed to it with no +`since` filter, and so does every test double. A backdated wrap is indistinguishable from a +fresh one unless something on the other end filters on time — and only a real server does. +There was even a test, `CVM-4-14`, asserting the *broken* behaviour ("the wrap timestamp is +shifted and must not be used for ordering"); it passed for the whole life of the transport. A +test that pins what the code does is not evidence about what the protocol needs. + +The fix is to send the real time, and the reasoning is worth keeping because the NIP-59 rule is +right in its own context: NIP-59 shifts the timestamp because a gift-wrapped DM is **stored** and +fetched later, so its timestamp would otherwise reveal when a conversation happened. A ContextVM +wrap carries an RPC request to a peer listening right now. The shift also protects nothing here — +CEP-4 puts the recipient in a visible `p` tag, delivery is real time, and kind 21059 is ephemeral +so no relay retains it — so it hid from an observer a fact that same observer reads off the +socket, at the cost of the request never arriving. `CVM-4-14` now asserts the send time. + +### Finding 2 — self-echo bookkeeping does not survive a process boundary + +With delivery working, a client's own traffic came back to it as `undecryptable`: alice's +`fetch` after her own invite and message reported `cursor 1: Authentication failed` (her Commit, +sealed under the pre-commit epoch key she has since left) and `cursor 2: Generation 0 already +consumed` (her own message, whose sender ratchet has moved on). + +The cause is that `GroupInbox` holds `pendingOperations` and `ownMessageCursors` in memory while +the cursor beside them is persisted. Post advances neither cursor nor disk — correctly, since a +lower cursor may still hold somebody else's unprocessed message — so a client that exits between +posting and ingesting starts the next run with a cursor that will re-read its own traffic and no +record that it is its own. + +`amy` exposes this on every run because each verb is a process. It is **not** an `amy` bug: the +Android app hits it whenever the OS kills it between sending and syncing, which is ordinary. The +visible damage is a gap in the sender's own conversation. The latent damage is worse and narrower: +`Ingestion.SelfEchoUnapplied` is how a client that died mid-post applies its own Commit, and that +recovery path depends on exactly the record that dying destroys. + +Fixed by persisting the bookkeeping next to the cursor — see the commit that follows this one. + +### What Tier B is, and is not + +These are both **transport and bookkeeping** bugs.

A sender's own stream entries came back as `undecryptable`: its Commit, sealed under the pre-commit epoch key it has since left, and its message, from a ratchet generation already consumed. The record of what is ours lived in memory while the cursor beside it was persisted. That asymmetry is not obvious until something crosses a process boundary, because posting deliberately does **not** advance the cursor — a lower cursor may still hold somebody else's unprocessed message — so the next run is guaranteed to re-read what this one posted, and needs to be told it is its own. `EchoState` is that record, saved beside `GroupCursor` on the same beat and deleted when there is nothing pending. Own-message cursors at or below the fetch cursor are pruned, because the stream has delivered them and they can never come round again. Pending Commits are kept until their echo matches, however long that takes: `Ingestion.SelfEchoUnapplied` is how a client that posted a Commit and died before adopting it applies its own Commit, and that echo is the only copy it will ever be offered. `amy` exposed this on every run because each verb is a process, but it is not an `amy` bug. The Android app hits it whenever the OS kills it between sending and syncing, which is the ordinary case rather than a corner. Two levels of damage, and the quieter one is worse: a visible gap in the sender's own conversation, and a recovery path that depended on exactly the record that dying destroyed. **The tests that let it through.** `a group survives a restart` already claimed to cover this, with `assertTrue(delivered.none { it is Delivery.Message })`. An `Undecryptable` is not a `Message`, so a gap in your own conversation satisfied the assertion. The lesson is narrow and reusable: an assertion about what a delivery is *not* passes for every outcome nobody thought of. Both restart tests now assert what it **is** — `Echo` — and both fail if either half of the persistence is removed (verified by removing each half in turn). Feeding an unrecognised Commit back through the engine, rather than reporting it, would have been worse than the gap: the epoch advances twice and the sender desynchronises from every other member, with the failure surfacing several epochs later as "my messages stopped decrypting" and nothing pointing at the cause. So the pre-existing `Undecryptable` outcome was the right failure mode to have — it just should never have been reached. `cli/tests/cordn/tier-b.sh` now passes end to end against the reference coordinator: handshake, `kp_publish`, group create, invite, Welcome opened without joining, join, messages both ways with the sender's own traffic reported as echoes, and both sides agreeing on epoch 1 and the same two members.

All false since yesterday, and the kind of stale line that gets believed because it is in a plan. The UI plan's open question 1 is the one worth reading rather than diffing. It has not been answered — shipping is still the maintainer's call — but it has narrowed, and in a way that cuts both directions. "Untested against a real peer" is no longer an argument, because Tier B passes end to end. The licensing half is untouched and was always the sharper one: a coordinator we may not depend on cannot go in CI, cannot gate a release, and cannot be pointed at a user. And the two bugs Tier B found were invisible to five tiers of our own tests, which is evidence either that the live tier works or that we do not know what else is hiding — depending on which way you read it.

From 1741077c4d03025ad830d21cfa10c1cf21ee9900 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 22 Sep 2026 13:53:56 +0000 Subject: [PATCH 057/148] test(cordn): put our MLS and theirs in one group MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tier B runs amy against amy through the reference coordinator. Both MLS endpoints are ours, so the ratchet tree, the Welcome and the Commit only ever agree with themselves — it proves the transport and the coordinator client and nothing about RFC 9420 interop. `interop-client.sh` closes that: `@cordn/cli` (ts-mls) on one end, amy (quartz) on the other, one group, live wire. That half is MIT and comes from npm; only the coordinator underneath it carries the licensing problem, and `stack.sh` now holds that warning in one place for both harnesses. Three directions, and the third is why it was worth building. 1. **Their group, our joiner.** Our engine opens a ts-mls Welcome and reads their GroupContext extensions, metadata and credentials out of it. 2. **Our group, their joiner.** Their engine opens OUR Welcome — the direction no fixture can test, because a fixture we wrote accepts what we emit by construction. 3. **Our later Commit.** Until here their epoch came from a Welcome, which carries the group state ready-made. This is the first time they must apply one of our handshake messages, and ours are public-framed (wireformat 2) where theirs are private-framed. `CordnGroupManager.invite` has asserted in its KDoc since it was written that their `processMessageBase64` admits both — a claim read off their source and never executed. It holds. All of it passes, and the harness bites: sealing `result.commitBytes` instead of `result.framedCommitBytes` fails direction 3 and the third-member join while **leaving direction 2 green**, because a peer that joined by Welcome never parses that Commit and only stalls once it has to. That is exactly why direction 3 is its own case rather than a variation of 2, and it is now demonstrated instead of argued. `amy cordn invite` gained a `kp_ref` field on the way: the harness needs to tell their client which Welcome to accept, and reporting it is right anyway — a KeyPackage is one-time, so the invite names something the invitee can no longer be invited with by anyone else. One asymmetry found and deliberately left open: the reference client sends kind 25910 **in the clear** where we pin `EncryptionMode.REQUIRED` and always gift-wrap (§8.6). Both work, so nothing is broken — but the two clients exercise different halves of CEP-4 against the same server, and our encrypted path is the one with no second implementation behind it. That is a Tier D vector exchange, not something this harness can settle. `tier-b.sh` is refactored onto `stack.sh` rather than keeping a second copy of the boot; re-run after the refactor and still green. Note on the suite: `Nip46ConsentInfoBuilderTest` failed once mid-session and has not reproduced — not in isolation, not in two full `./gradlew test` runs, not in a `--rerun-tasks` rebuild of that module. Its inputs are constants and its collaborator is injected, so there is no nondeterminism in the test itself; the likeliest cause is a stale incremental artifact, the same failure mode that hit `:commons:jvmTest` earlier today. Recording it rather than calling it a flake, because the report was overwritten before I could read it and I cannot prove which it was.

What the coordinator can see From 417cb20288717e7558ef5562f0c347c8883b7e31 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 22 Sep 2026 18:15:36 +0000 Subject: [PATCH 058/148] fix(cordn,marmot): five bugs an audit of the branch turned up MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All five are things that fail silently — nothing throws, no test went red, and four of them only ever show up as data that is quietly gone or a rule that quietly stopped applying. Each fix has a test that fails without it. **Marmot's authorization gate was off on the convergence path.** `MlsCandidateStateEngine` restored groups with `MlsGroup.restore(state)`, whose policy parameter defaults to `MlsGroupPolicy.Permissive` — a no-op `authorizeCommit`. So `isAuthorized` returned true for every commit it could parse, and a non-admin could get an admin-removing Commit accepted by convergence. MIP-03's rules used to live inside `MlsGroup` and ran by construction; moving them behind the policy seam on this branch turned "forgot to pass it" from a compile error into a silent bypass. The policy is now a constructor parameter, passed on all six restores, with the trap written down where the next caller will read it. Worth noting what did NOT break: `currentAdminIdentities()` calls `MarmotGroupPolicy` directly rather than through the group, so the admin set always read correctly and the bootstrap short-circuit behaved. Only the gate itself was dead. **cordn attachments died at the next Commit.** The media file key was the group's current epoch exporter, and cordn retains no past epochs — so every photo and voice note became permanently unopenable the moment anyone joined or left, for the sender too, with nothing failing until somebody scrolled back to a broken image. The key is now random per file and carried in the `imeta` descriptor, which already rides inside the MLS envelope: as confidential as the message, and now as durable. Forward secrecy is unchanged — a new member cannot read the messages carrying those keys either. It also retires a sharp edge the old design had. One key per epoch meant the nonce was the only thing separating two files' keystreams, so a repeated nonce was a keystream-reuse break across every file in that epoch. Now a nonce is used once, under a key used once. **Any relay peer could forge a coordinator response.** `CvmTransport` correlated only on the `e` tag and the JSON-RPC id, and skipped the tag check when it was absent — which `CVM-CORE-15` establishes is allowed. A client subscribes to everything `p`-tagged to its own key, and `unwrap` verifies the inner signature without knowing whose it should be, so a stranger could answer `kp_take` with their own KeyPackage and be invited into the group. Responses must now come from `serverPubKey`, which is the coordinator's only identity (§8.5). **A coordinator that failed to open was erased.** `remember()` persisted `registry.coordinators`, which is the coordinators with an *open session*, so one unreachable relay plus one successful open silently deleted the first from disk — "your relay was down" becoming "your groups are gone". It now merges with what is already stored, keyed by pubkey. This also fixes `importArchive`, whose `start()` was overwriting its own just-restored list the same way. **Two concurrent requests could share a subscription id.** `nextId++` in a companion object is not atomic, and `CvmTransport` opens one subscription per request while the sync loop and UI issue requests concurrently. A collision means the first `close()` unsubscribes both and the other request waits out its full 20-second timeout. Now `RandomInstance.randomChars`, which is how the rest of the relay client names subscriptions — no shared counter to race. **CEP-22 admitted transfers it always rejected.** Nothing drains `chunks` before `onEnd`, so `maxPendingChunks` (256) is the ceiling on a whole transfer rather than a reordering window, while `maxTotalChunks` (4096) governs what a peer may declare. Anything between the two passed `start` and then died at chunk 257 — the same refusal, after megabytes had moved. Checked at `start` now, and the limit's KDoc says what it actually bounds. On the audit itself: two of the reported findings were overstated and I checked before acting. One claimed `currentAdminIdentities` was affected (it is not, per above). And my first attempt at the forgery test passed against the unfixed code — a second fixture never sees a request `p`-tagged to the real server, so it was timing out for the wrong reason. Publishing the forged event straight to the pool fixes that, and the mutation now kills it. A test that goes green against the bug it is written for is worse than no test.

The message says why, and it is not about that test: UncaughtExceptionsBeforeTest: There were uncaught exceptions before the test started. Some coroutine threw where nobody was catching, the exception went to the THREAD's uncaught handler, and `runTest` in whichever test started next reported it. The victim is chosen by timing, which is why it moves between classes and variants and never reproduces on its own. I gave a wrong explanation for this in the commit that first recorded it (`1741077c` said the likeliest cause was a stale incremental artifact). It is not — it is a real leak, and the report being overwritten before I read it is what let the wrong theory stand. `CordnRuntimeTest` is a candidate worth eliminating: it builds bare `CoroutineScope(Dispatchers.Default + Job())` scopes, which have no handler, and its `@After` cancel races whatever `CordnRuntime` still has in flight — exactly the shape that produces this. So the scopes now carry a `CoroutineExceptionHandler` that collects, and `cleanup` fails **this** test if anything real was collected, ignoring the `CancellationException`s that cancelling is supposed to produce. That is a diagnosis either way. If this suite is the leaker, an intermittent failure in an unrelated class becomes a deterministic one here, naming the throwable. If it is not, a candidate is gone and the handler costs nothing. No leak has been caught yet — it did not reproduce in a full clean run of the module or in repeat runs of this class — so this is a net, not a fix, and the underlying leak may still be somewhere else in `:amethyst`.

It is innocent. The leaker is `CalendarsViewModelTest`, and the evidence is its own captured stderr: DispatchException: Coroutine dispatcher Dispatchers.Main threw an exception, context = [..., StandaloneCoroutine{Cancelling}, Dispatchers.Main] Caused by: IllegalStateException: Dispatchers.Main was accessed when the platform dispatcher was absent and the test dispatcher was unset. `store.clear()` cancels `viewModelScope` but does not wait for it. A child completing on a Default worker resumes onto `Dispatchers.Main`; if `resetMain()` already ran, that resume throws on a background thread. Nothing in that suite fails — the next test in the JVM to call `runTest` does, with `UncaughtExceptionsBeforeTest`, which is why the blame lands on a stranger and why it vanishes under `--tests`. Not fixed here, deliberately. The usual remedy — drive Main from a TestDispatcher and advance it in `tearDown` — changes when `stateIn`'s sharing coroutine runs, and that suite relies on `Unconfined` running it eagerly at construction. Getting that right needs someone who knows what those ViewModels are supposed to do at startup; guessing at it from outside the calendar code is how a flake becomes a wrong test. So this records the diagnosis, the trace and the two candidate fixes where the next person will look, and leaves the change to whoever owns it. Two corrections to my own earlier claims, both in commits already pushed: `1741077c` blamed a stale incremental artifact, and `593914ab` treated `CordnRuntimeTest` as the likely leaker. Neither is right. The handler added in `593914ab` still earns its place — it is what proved that suite innocent.

Every derived flow in `CalendarsViewModel` is `flowOn(Dispatchers.Default).stateIn(viewModelScope, ...)`. `store.clear()` CANCELS viewModelScope but does not WAIT for it, so a cancelled upstream finishes on a Default worker and resumes its Main-side parent — and if `resetMain()` already ran, that resume throws on a background thread. Nothing in this suite fails; the next test in the JVM to call `runTest` does, with `UncaughtExceptionsBeforeTest`. `Nip46ConsentInfoBuilderTest` wore the blame for it across three sessions and passes in isolation every time. The fix round-trips through the Default pool while Main is still valid, so those completions land before the dispatcher goes away. **This is a mitigation, not a proof, and the comment says so.** There is no public handle on viewModelScope's Job to join, and a thread pool offers no "everything queued has run" barrier — the window is closed, not removed. The real fix is for the ViewModel to take its dispatcher as a parameter, at which point the test supplies one it can drain deterministically. That is a change to production code in someone else's area, which is not the right thing to make under a push deadline, so the note points at it instead.

The mitigation in the previous commit therefore did nothing for roughly half the occurrences, which is how the flake survived it. Its own class comment already reasoned about this and stopped one step short. Unconfined makes cancellation finish synchronously on the cancelling thread — true, and it is why the comment says the problem is handled. But it only covers the coroutines Main owns. Every derived flow is `flowOn(Dispatchers.Default)`, so the upstreams run on the pool, and a cancelled one completes on a Default worker and resumes its Main-side parent from there, after `resetMain()`. Same drain applied, same caveat recorded. Evidence, since the last commit claimed a fix I could not back up: - 4 clean Fdroid runs and 3 clean Play runs after this change - 0 suites emitting `Dispatchers.Main was accessed when the platform dispatcher was absent` across all preserved results, where before it was reliably one A SEPARATE intermittent turned up while hammering `--rerun` and is NOT this one and NOT fixed: `NewMessageTaggerKeyParseTest` failed all 10 of its tests with `NoClassDefFoundError: com/vitorpamplona/amethyst/ui/actions/NewMessageTagger`, twice in about eight runs, and passed on either side of both. A whole class failing to load is a build-artifact symptom rather than a code one — which is, with some irony, exactly the explanation I wrongly attached to the dispatcher leak three commits ago. Recording it rather than guessing at it; it may well be an artifact of re-running the same task in a tight loop, which is not how anyone builds.

Measured on the public relays, that split the newest 100 announcements into 42 coordinators and 58 unrelated servers. The one thing an announcement does not carry is where to reach the coordinator — no routing tag exists, per §8.5 — so discovery records the relays that *delivered* it instead. That is why each relay is queried in its own call: fetchAllWithHooks deduplicates by event id across every relay in one call, which would credit each announcement to whichever relay answered first and drop the rest of the reachable set. Origin.ANNOUNCEMENT marks the result as weaker than MANUAL: nobody vouched for it, and everything but the pubkey is self-asserted. The announced name is deliberately not copied into the user's label. Discovery does not filter by age and does not imply liveness. A coordinator that stopped running a month ago still has its replaceable announcement on the relay, and one that never announced is absent entirely — announcedAt is exposed so a caller can show that rather than hide it.

Some providers accept the bogus name, which is how the keys and encrypted files already on those devices came to be written under it. A Samsung API 34 tablet does not, and Cipher.getInstance throws NoSuchAlgorithmException straight out of KeyStoreEncryption's field initialiser; the API 36 emulator accepts it, which is why CI never sees this. Every guarded caller degraded silently there: AccountCacheState catches the throw and falls back to InMemoryMlsGroupStateStore, so Marmot group state was never persisted on that device and only a Log.e said so. cordn's CordnRuntime builds its blob cipher as an eager default argument inside Account., where nothing catches it, so the same throw aborted createAccount -> loadAccount -> startUI and the app sat on "Loading account" forever — no crash, no ANR, no retry, reproduced 3/3 with the process idle at ~3% CPU and zero relays dialed. Resolve the padding once per process, preferring the legacy name wherever a provider still offers it so existing keys and ciphertext — account secrets among them — stay readable, and pass the resolved value to setEncryptionPaddings in both key-generation paths. Build cordn's cipher lazily too. That alone fixes nothing, since the failure merely moves to first use, but it keeps a cordn-only failure out of the login path. Verified on the tablet: the account loads, the coordinator list persists, and a KeyPackage publishes to a live coordinator.

That is true of exactly one field and false of the feature, and the difference decides what a future revisit should be looking for. A group document's `clientState` is library-private on purpose — multi-device.md §4.2 says it is "library-serialized and intentionally not pinned to a wire format", with TLS pinned only for `lastResortKeyPackage`. So cross-client sync is ruled out by design and no work on our side changes it. But everything §14 lists as a MUST is vendor-neutral: the document shapes, the NIP-44 v2 DEK seal, sha256 addressing, highest-epoch-wins reconciliation, the {gid, epoch} tombstone, the sibling-skip rule, the tip format. An Amethyst-only fleet is buildable with MlsGroupState in that one field. It stays a non-goal on cost, now written down as such: it would ship §10's symmetric commit race, which the spec leaves unresolved (§15: "equal-epoch MLS states have no merge function"; automatic resolution is "possible but unspecified"), behind an always-on discipline — republish plus full tip rewrite after every epoch-advancing Commit, full reconcile before opening any delivery stream — on a Draft spec, for a feature no mixed-client user benefits from. Each plan now names the two independent conditions that would reopen it: a library-neutral clientState, or a specified equal-epoch tiebreaker. Also corrected the backup section's cross-reference, which borrowed §4.6's reasoning: it applies to cross-client portability specifically, and the fork-on-restore hazard is the same equal-epoch divergence, reached by restore rather than by a race.

One device writes a snapshot, one reads it, and the writer then stops. Nothing here implements §8.5 prev chains, §10 sibling-Commit convergence or §10.5's publish-on-every-Commit — those keep two *live* devices in step, which a handoff does not ask for, and §10's equal-epoch race is exactly what a handoff avoids by having only one writer. Three additive fields beyond the spec's group document, each because the spec has nowhere to say it and a migration loses user-visible data otherwise: - clientStateFormat. §4.2 leaves clientState library-private on purpose, so a ts-mls document is unreadable here and ours is unreadable there. With no marker that surfaces as a crash inside the MLS engine; with one, a reader refuses with a reason. Absent is treated as "not ours". - amethystRoomState / amethystEchoState / amethystJoinedViaRequest. CordnBackup's Archive carries none of these three even though FileCordnGroupStore persists them, so a restore there returns every room unread with the half-typed message gone and re-reports the old device's own traffic as a gap. Migration must not repeat that. A foreign reader ignores unknown fields, so none of this costs one anything. The seal is confidentiality-only by design (§7): a self-seal to a throwaway DEK, so anyone holding the DEK can encrypt as well as decrypt. Authenticity comes from the tip's owner-signed inner event, and integrity of a given blob from the address. verifyAddress is deliberately separate from open so the order is the caller's to get right: check the address first and a store serving wrong bytes never gets its plaintext to the parser. 26 tests. Mutation-verified: an always-true verifyAddress, a dropped schemaVersion check, a skipped-instead-of-refused gid-less tip entry, and dropping roomState/echoState from the encoder are each caught.

charset=UTF-8 Content-Transfer-Encoding: 8bit The §6/§11 connection string as a `cordndev1…` bech32 TLV, same shape as CordnGroupRef: the tip's ephemeral pubkey, its `d`, the relays to look on, and the outer kind (carried so changing it later cannot strand old codes). Two deliberate narrowings of §11, both because this is a handoff and not a fleet: - **No owner key material.** §4.3 is explicit that the documents do not provision identity, and neither does the code. The user signs in on the new phone by their usual means first — nsec, Amber, a bunker — and only then migrates cordn state onto it. - **No write key by default.** §11 bundles the ephemeral nsec so a new device can publish its own tip moves; a device being migrated *to* has no such need, and mints its own keypair when it is itself replaced. Leaving it out means a photographed QR is worth nothing: it names an event anyone could already fetch and only the owner can decrypt. With it, a leak also buys repointing the tip at a stale inventory — §13 calls that denial of service, and it is still real. writeKey defaults to null; readOnly() strips it. CordnGroupRef's strict TLV parser moved to a shared CordnStrictTlv rather than being copied: lenient parsing drops a malformed tail, which for a ref means silently reaching for a default coordinator and for a handoff code means silently losing a relay. 17 tests. Mutation-verified, and the first two attempts at the strictness test were vacuous — worth recording since the mistake is easy to repeat: chopping the encoder's own output truncates the *pubkey*, which a lenient parser rejects too, so it discriminates nothing. The payload is now hand built so the truncation lands on a trailing optional relay, where lenient parsing really does succeed with one fewer relay. A readOnly() that keeps the write key is also caught.

Two additive fields the spec has nowhere to put, both because migration loses something real without them: - coordinatorRelays. §4.1's `coordinator` is an identity and spec/00.md §8.5 says a coordinator has no address beyond its pubkey, so a device that has never talked to it has nowhere to learn where its traffic runs. A seeded group with no relays cannot sync. - the full key-package list. §11.5 carries only the last-resort package, because a fleet keeps one-use packages device-local — a sibling that cannot open one Welcome is an inconvenience while the publisher is still around. A phone being replaced is not still around, so a Welcome in flight against one of its one-use packages would be lost. CordnBlobStore is injected rather than depended on: the only Blossom uploader here needs an Android Context, and this has to run from amy and from a test. Its KDoc carries §12's requirement that BUD-01 auth be signed by an ephemeral key and never the owner — an implementation that authorizes as the owner satisfies the types and defeats the purpose. 13 tests, including a hand-built foreign-writer tip (real document, real address, real owner signature, ts-mls clientState) which is the only way the engine-mismatch path is reachable — our own publish cannot produce it. Mutation-verified: skipping the address check, skipping the inner-signature check, and publishing a tip naming blobs no server accepted are each caught. Two corrections found that way: - the first engine-mismatch test re-sealed a document in the fake store, which changes its address, so the §6 check fired first and the test proved nothing about the format marker. - the KDoc claimed the inner signature was what made the inventory the account's own. It is not — the outer content is a self-seal, so only the owner can write a tip the owner will read. The signature check is defence in depth against a writer-side bug; the address check is the one guarding against an outsider, because the storage server picks the bytes.

Two phones holding one MLS leaf and both committing fork the ratchet tree, and MLS does not recover: after the fork every message silently fails to decrypt for somebody. CordnHandoffState is that flag, persisted as a zero-byte marker rather than an encrypted blob. A flag that failed to decrypt would fail open, and failing open here means a device that quietly resumes committing after handing its groups away — the exact fork it exists to prevent. Enforced at CordnRuntime.session(), which every epoch-advancing path goes through. Reads of state already in memory are deliberately left alone: showing a user the conversations they had is harmless, and refusing would make a failed migration look like data loss. restore() also declines to open any session at all when the flag is set, so a relaunch does not quietly bring the loops back. Reversible, because a migration can fail after the export — a flat battery, a QR that will not scan — and locking irreversibly would strand an account on the device holding the only copy of its state. Adopting a snapshot also clears it, since a device that just adopted now holds the newest copy. handOff() publishes first and marks second, so a failed publish never leaves a locked device. 17 tests. Mutation-verified: dropping the check from session(), a flag that does not survive a restart, and a resume() that does not clear it are each caught.

The snapshot read/write moved to CordnMigrationStores in commons first — duplicating it would let the CLI and the app disagree about what a migration carries, which a user meets as a conversation that arrived on one path and not the other. HttpCordnBlobStore is a JVM Blossom client, needed because the app's uploader wants an Android Context for a MIME lookup a migration blob does not have — every document is opaque bytes. Its BUD-01 auth is signed by a per-instance ephemeral key, never the account: §12 requires that, and signing as the owner would tell the storage server in the clear that this npub is uploading right now, which is the linkage the opaque tip exists to prevent. migrate.sh runs it for real: geode, the reference coordinator, and a throwaway python blob server. One identity on two HOMEs, a group created on the old one, and the new one starting from an empty directory and the scanned string alone. Verified end to end — code minted, 2 blobs on the server, and the same gid live on the new device. `export` does not stand amy down the way the phone does. amy keeps no sync loop — each invocation is a process — so there is nothing to stop and a flag that claimed otherwise would be theatre. The output says `this_device_stopped: false` rather than implying a guarantee the CLI cannot make; the check lives on the runtime that actually holds loops open. One harness bug worth recording: the first "a stranger's code is refused" check ran through a helper that sends stderr to /dev/null, and --json writes errors there, so it compared an empty string and passed for the wrong reason.

That store does NOT reuse account.createBlossomUploadAuth the way CordnMediaService does. §12 requires the BUD-01 authorization to be signed by an ephemeral key and never the owner npub — signing as the owner would tell the storage server, under the account's own name, that this person is uploading right now, which is the linkage the opaque tip exists to prevent and would arrive by a side door. Message attachments are already attributable; a migration blob is meant to link to nobody. Two things are said where they are decided rather than in a help page, because neither is discoverable afterwards and both are irreversible in the ways that matter: before exporting, that the encrypted documents leave the device for a storage server; before importing, that this replaces whatever cordn groups are already here, because MLS state cannot be merged. The handed-off state is deliberately not phrased as an error — nothing broke and nothing was deleted, the device stood down on purpose, and taking it back is one button. The settings entry answers the earlier question: cordn had four flat rows (link, coordinators, key packages, backup) and migration would have made five, which made it the largest feature in the account settings list by count and among the least used. They are now one "cordn" entry into a hub holding all five, still searchable under one name a user would look for. ./gradlew test green; all three Marmot/cordn isolation guards pass.

From 78e1f7e205f4611870fc6974ceefcf096dbd81f9 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 23 Sep 2026 02:46:30 +0000 Subject: [PATCH 073/148] docs(cordn): record that migration landed and the fleet did not MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both plans said multi-device was a non-goal. That is now true of exactly half of it, and the halves have different reasons. A live fleet is still out: §10's equal-epoch race has no resolution in the spec, and keeping two devices in step is what needs one. Migration is in: a handoff has a single writer, so that race is unreachable by construction rather than by mitigation. §5.3 now carries the inventory of what shipped, what was deliberately not shipped (§8.5 prev chains, §10 sibling-Commit convergence, §10.5 publish-on-every-Commit, §8 tombstones — each exists for a fleet), the five additive document fields and why each one is not optional for a phone that is going away, and the cost that was weighed: sealed group state, leaf private keys included, sits on a storage server until the blobs are deleted. Cross-client migration is unchanged and still impossible by design.

EncryptionMode. REQUIRED documents that it fails loudly rather than downgrading, but its input was a constant, so the promise could never fire; CEP-19's fallback to the persistent wrap had the same problem in reverse. The rule is: a peer that declares a surface is believed, a peer that declares nothing leaves the assumption in place. The second half is not leniency for its own sake — a real coordinator's kind-25910 responses carry only [["p",..],["e",..]], no discovery tags at all, so reading silence as a full surface would say every deployed coordinator supports nothing and REQUIRED would refuse to talk to all of them. - DiscoverySurface.declaresNothing tells an all-default surface apart from a declaration. - SessionDiscovery.declaredPeer is the baseline only when it declares something. - The two constructor flags are renamed assumePeerSupportsEncryption / assumePeerSupportsEphemeralWrap: they are the prior, not the answer. Both stay optimistic by default. Assuming a peer cannot encrypt would send the first request of every session in the clear, which is the one message whose exposure is still avoidable. Five tests, each checked against a mutant: hardcoding either flag back to a constant, and reading silence as a declaration, all now fail.

We declared no CEP-35 surface at all. `initialize`'s capabilityTags defaulted to empty and nothing ever passed any, so a spec-correct ContextVM server learned nothing about us — and it only chunks a CEP-22 response, or opens a CEP-41 stream, for a client that declared it can take one. Both profiles were dead on every live session, which is also why msg_sub_many has never had a live proof. The surface now rides the session's first message whatever that message is, since a session that opens with a tool call rather than a handshake would otherwise still declare nothing. 2. A completed transfer could not end the call. `onNotification` returned Unit, so after reassembling the response the transport went back to waiting for a direct one — which a chunking server never sends, the chunked response being the response. It returns JsonRpcMessage? now; non-null completes the call. CEP-41 keeps returning null, because `close` is not an answer. The unit test missed this by having the fixture ALSO answer normally, so the call was ended by that answer and reassembly only had to win a tie-break. The fixture now sends frames and nothing else, and the test fails without the fix. 3. The deadline bounded the whole call. Both profiles deliver one response as a run of notifications, each its own signed, wrapped, published relay event, so a 100 KB transfer ran past the 20 s default and was killed mid-run with every frame arriving and parsing correctly. timeoutMs now bounds silence, which is what a caller actually wants bounded. Subscriptions keep the old meaning through an explicit TimeoutMode.TOTAL: their timeout is a budget the sync loop re-opens on, and a busy stream bounded by silence would never return. Harness: tier-b.sh gains the three tools the two-party lifecycle never reaches — join_request_store, join_request_take_many and kp_remove, via a third account who asks to join rather than being invited — plus a backlog big enough to trip the coordinator's 48000-byte threshold. `cordn fetch --json` reports oversized_transfers so the run can tell a server that chunked from one that never had to; without it a reassembled response is indistinguishable from a direct one, by design. Also corrects an assertion I had backwards: reading a join request does not consume it. Retirement rides the next call after an accept or decline, so a reader that lost its process between listing and accepting has to still find the request — two amy runs are exactly that case. Verified live against the reference coordinator: TIER B PASSED with oversized_transfers=1, and CLIENT INTEROP PASSED unchanged.

Git merged the files cleanly because nothing textually conflicted - the ten cordn screens are new on this branch, so they still named the old packages and only the Android compile noticed.

Subject: [PATCH 077/148] fix(contextvm): a subscription ended in an exception, always MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit msg_sub_many was the last of the eleven coordinator tools with no live proof, and pointing a harness at it showed why: it could not succeed. CEP-41 says a stream's `close` does not complete the JSON-RPC request, so an open-ended subscription has no response to wait for — its budget running out is the only way it can ever end. callTool let that timeout propagate, so every subscription, however healthy, finished by throwing. CordnSyncLoop read that as a failure and went into backoff after each one. Under TimeoutMode.TOTAL the budget is now a normal return with whatever the stream delivered; IDLE still throws, because there silence really is a stalled peer. The fixture missed it by answering the subscribe call like any other request, which no coordinator does. CordnGroupManager.subscribe also persists on the way out now, like catchUp and for the same reason: delivering a message advances the ratchet and the cursor, so a subscription that ended without writing left that progress only in memory. A long-lived host survives it; a process-per-command client does not, and neither does a crash. New verb: `amy cordn watch [--timeout MS]`. It calls msg_sub_many and nothing else, so what it prints arrived over an open stream rather than a poll — the only way to exercise the one tool a request/response client never reaches. `fetch` and `watch` now share one delivery collector instead of two copies of the same when-branch. tier-b.sh gains the step, ordered so it proves something: the watcher goes up FIRST and only then does alice send, because a message sent beforehand would be backlog the subscription replays. A second step checks the cursor survived the watching process — removing the persist makes that one fail, so it is not decoration. Verified live: TIER B PASSED, with the message arriving under "via": "msg_sub_many" and not coming back on the next fetch.

The screen's own comment says health is "only ever what a call of ours already observed", and this is one — usually the very first, since the button exists so someone can find out whether a coordinator they just added answers at all. Recorded in `CordnSession.serverInfo` now, where the session already holds the health it feeds. An answer counts as a success and a throw as a failure; `null` counts as neither, because a scope that did no handshake returns `null` and a call that never left the device must not report a coordinator as reachable. **"1 single-use packages available."** — and "1 packages this device cannot open". Both are now plurals. Three tests cover the health path: an answer marks it observed, a throw counts a failure and keeps its reason, and silence leaves it unknown. --- The live migrate harness could not run on this machine at all; none of it was the product. - `stack.sh` ran the coordinator with `--network host` so it could reach a relay on the host's loopback. On Docker Desktop the daemon is inside a VM, so that is the *VM's* loopback and `127.0.0.1:$PORT` is nothing: the coordinator retried "Relay connection error" until `stack_up` gave up waiting for a pubkey that was never coming. It now uses `host.docker.internal` off Linux and keeps `--network host` on it. - `BLOB_PORT` defaulted to **877**, which is privileged, so the blob stand-in died with `PermissionError` for anyone who is not root — on Linux too. Now 8877. - `blob_up` did not check the server came up. A dead one surfaced thirty lines later as `migrate export` reporting "no server accepted the document", plus two more failures behind it, none naming the blob server. It now waits for the port and exits 2 with the real error. With those, `cli/tests/cordn/migrate.sh` passes end to end on stock defaults. Worth knowing for whoever runs it next: the image is amd64-only, so on Apple Silicon the pull needs `--platform linux/amd64` and then runs emulated.

These are the six that are small and unambiguous; the other four are design-level and are written up separately rather than fixed in passing. - The fixture coordinator's `join_request_store` stored `at = clock++` and returned `clock`, so the value a caller acked with was always one past the value stored. Nothing could ever be retired. - `join_request_take_many` ignored `consumed` outright, which made retirement a no-op in every fixture-backed test: an answered request came back forever and no test could notice. It now retires exactly as `welcome_take` beside it does. - `pendingWelcomes` passed `drainRetirements()` inline, emptying the queue before the call it rode on. A failing `takeWelcomes` dropped those acks permanently and the coordinator kept re-serving consumed Welcomes. The join-request path already re-queued on failure; this matches it. - A cordn last-resort KeyPackage carries its marker inside `app_data_dictionary` (0x0006) but advertised leaf capabilities that did not include it. `CordnGroupPolicy.lastResortLeafCapabilities()` existed for precisely this and was called from nowhere. - `OpenStreamReceiver.lastActivityMs` started at 0, so against a real clock `needsProbe()` was true from construction — thirty-odd years idle before the first frame. Only a test calls it today, which is why it went unnoticed. - `KeyStoreCordnBlobCipher` serialised every cordn KeyStore encrypt and decrypt behind a lock whose justification no longer holds: `KeyStoreEncryption` keeps its `Cipher` in a `ThreadLocal` now, so the init/doFinal pair cannot interleave and the lock only cost concurrency. The KDoc explaining the old hazard is replaced by one explaining why there is no longer a lock. Incidental, from the merge: `EXTERNAL_SENDERS_EXTENSION_TYPE` was 0x0004, the same value as `EXTERNAL_PUB_EXTENSION_TYPE`. RFC 9420 §13.3 assigns it 0x0005.

That direction lets the cipher choose its own nonce and passes no spec at all, so every store built on this class could write bytes it was then unable to read back — and the class backs rather a lot: `KeyStoreCordnBlobCipher`, `AccountSecretsEncryptedStores`, `EncryptedDataStore`, and Marmot's group-state, key-package, obligation and message stores. Found by driving cordn on an SM-T220. Coordinators added in one session were gone on the next launch — "No coordinators yet" on the settings screen and "You have no coordinator open" on the invitations screen — while `cordn//coordinators` sat on disk at 259 bytes, alongside the group and its key packages. Nothing was logged, because of the second half of this commit. `FileCordnCoordinatorStore.load` catches everything and returns an empty list rather than failing login, which is the right call; doing it silently is not. Losing that list loses every cordn group with it — the MLS state stays on disk, but a gid whose coordinator is unknown is not a group anyone can open — and it looks exactly like an account that never had a coordinator. One warning line is the difference between a diagnosable fault and a mystery; without adding it this would still be unexplained. Verified on the device: after the fix a cold start logs nothing, both coordinators come back, and the one that is reachable reports live health.

Added one on `runtime.groups.all`. Deliberately without the `drop(1)` its neighbours use. They drop the replay because the feed's first build already saw their state; cordn restores in its own launch from `Account`'s constructor and usually finishes *after* that build, so the replayed current value is precisely the one that matters. With the drop, an account whose rooms are all restored rather than newly created waits for a change that never comes. 2. `ChatroomHeaderCompose` renders an event-less row only for the gatherer types on its `rendersWithoutEvent` list, and `CordnGroupChatroom` was not on it. A cordn row has no event *ever* — not merely before its first message — so every one of them took the branch that waits for an event and drew `BlankNote()`. The room was in the feed the whole time with no pixels: the blank rows at the bottom of a long inbox were the cordn rooms. Until both were fixed a group was unreachable the moment its screen closed, because the inbox row is the only way back into one. **Sending could fail without saying anything.** Every outbound action went through `manager()?.post(…)` inside a `scope.launch` with no `catch`. `manager()` is `sessionOrNull(…)?.manager`, so a room whose coordinator has no open session swallowed sends, reactions, edits, deletions and pins — and the composer had already cleared the draft, so the text went too. From the outside that is exactly what a message that was sent and never arrived looks like, which is how it was found: a reply and a reaction that the coordinator never received. One `trySend` now carries every outbound action. It names the missing session, logs and shows anything thrown, and on failure hands the draft back along with the reply or edit it belonged to, so trying again is one tap. Verified on an SM-T220 against cordn.net's coordinator: after a cold start the room shows as "Edo and Amy" with its cordn badge and opens. Known remaining: that row's preview reads "No messages yet" for a room that has messages. Separate from either fault here and not yet diagnosed.

Fourteen settings screens use SettingsSection/SettingsItem/SettingsControlRow out of SettingsSectionCard.kt; none of the six cordn screens did. There was no reason for it — those composables are `internal`, which in Kotlin is module-wide, and settings/cordn/ is in the same module. I built these pages without checking what the settings package already had, which is exactly the survey step CLAUDE.md's Feature Workflow asks for and which I did do for the protocol and state layers. The hub is now what it should have been: two SettingsSections ("The coordinator", "This device") of grouped rows in one 20dp card, each row a leading icon in a tinted box, title, description and chevron, with SettingsDividers between and the canonical outer geometry. Its rows go through SettingsControlRow rather than SettingsItem because every page behind this hub is obscure enough that its title alone does not say what it does, and SettingsItem has no room for a description; the chevron rides the trailing slot. No new icon codepoints — Dns, Key, Link, Save and SwapHoriz are all in the subset font already, so it needs no regeneration. The other five are forms and action pages rather than settings lists, so they get the shared geometry (horizontal 16 / vertical 12, spacedBy 20) but not a mechanical conversion; grouping their blocks into SettingsSections is a real piece of work and is called out rather than half-done. Adds the first ThemeComparisonColumn preview under settings/cordn/.

The machinery to do better was already in the same files: mentions inside a message body resolved through observeUserName, and the inbox row that leads into the room resolved names too — so the room was inconsistent with its own entrance. - The chat author line is a 24dp avatar and a name. - The invitation card shows up to five faces and names the first three. It said "3 members" before and never who: the roster is in the Welcome already, and deciding whether to join an encrypted group is exactly the moment that number is no use on its own. - Group info lists the roster with an Admin badge rather than a count, for a screen whose whole subject is who can read you. - A join request names the person asking. Admitting someone to an encrypted group off sixteen hex characters is not a decision anyone can actually make. observeUserNameByHex falls back to the same hex prefix until the profile arrives, so nothing regresses while it loads.

Adding a coordinator meant pasting a 64-character public key and a list of relay URLs, which nobody can do without being handed the answer out of band. The picker now reads CEP-6 announcements off the account's outbox relays and lists what it finds: the coordinator's own name and description, the relays that carried it, and how long ago it last announced. That last line earns its place — the live survey behind this feature found 41 of 42 announcing coordinators were months-dead browser demos. Deliberate choices: - Not automatic on entry. The query touches no coordinator, but it is still the user's relays being asked something on their behalf, and a screen that reaches out the moment it opens is what this feature is supposed to be careful about. - Already-added coordinators are dropped from the list rather than shown disabled: it answers "what could I add", and a dead row is one more thing to read. - "Nobody is announcing" and "nothing found, and N relays did not answer" are different sentences, because only one of them is final. - The announced name never becomes the label. A coordinator cannot prove a name; a label is the user's own word. toConfig() already refused to launder one into the other and this respects that. Uses the app's CrossfadeIfEnabled, so performance mode still turns the animation off.

Your own traffic comes back recognised by cursor and reported as Delivery.Echo, whose branch adds nothing, and no send path added anything either — so a message, a reaction, an edit, a deletion, a pin, an attachment and a voice note all appeared to do nothing at all. Deleting your own message looked like a no-op until somebody else's traffic refreshed the fold. - send/post now return CordnDeliveredMessage rather than CordnEnvelope, carrying the cursor the coordinator assigned. Guessing one would put your own message in the wrong place until the echo corrected it, since CordnGroupChatroom.ORDER sorts on it. - trySend adds the result to the room. add() is keyed on the envelope id and idempotent, so a later re-sync that does hand the message back cannot double it. - The three annotation paths that bypassed trySend — delete, pin toggle, and unpin from the ribbon — go through it now, so they report failures too. PinnedRibbon takes an onUnpin callback instead of a manager: a ribbon that posted for itself could neither report nor record. - Attachments and voice notes add their own message the same way. The list is reverseLayout with the rows reversed to match, so a room opens on its newest message and an arrival while you sit at the bottom keeps you there instead of pushing the conversation out of view. amy's `cordn send --json` gains a "cursor" field, which is where the message landed in the stream — previously discarded.

None of the nine cordn screens used any of them: a coordinator-less account got one sentence stranded in the top-left corner of an otherwise blank page, on seven different screens. Those seven now use EmptyState — centred, titled, and with a second line saying what to do about it, which the bare Text never did. Seven of the nine screens also tracked a `busy` flag and spent it only on `enabled = !busy`, so the entire signal that anything was happening was a button turning grey. Backup and restore derive their key with scrypt, which is slow by design; migration publishes to relays. "Grey for several seconds" is indistinguishable from "did not register the tap". A small BusyLabel puts a spinner in the button, and migrate keeps its "Exporting…" text swap alongside it — the word says what, the spinner says still. Backup's outcomes move to a snackbar. They were two Text lines at the foot of a scrolling form: easy to scroll past, never dismissed once shown, and a failed export sat under a button that still looked ready. Deliberately not converted: the per-coordinator error on the key-package cards and the per-step errors in migrate. Both sit next to the control that failed, which is better placement than a global snackbar, and hoisting them would have flattened state that is scoped per coordinator and per step. A first pass at this moved them anyway and broke both files; this is the corrected version.

Look for coordinators From 0b8b2c0c1c87cd651049b814418cac0d934eb6c8 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 24 Sep 2026 02:26:08 +0000 Subject: [PATCH 088/148] feat(cordn): group a speaker's burst, and divide the days MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A cordn room was an undivided column that repeated the avatar and name on every single line, so a run of six messages from one person looked like six separate arrivals and yesterday evening sat flush against this morning. - Consecutive messages from the same sender within five minutes drop the author row. Time as well as sender, because a reply hours later to your own last message is a new thought and hiding the name on it reads as though the conversation never paused. - A day divider under the first message of each day: Today, Yesterday, then "d MMM", with the year only when it is not the current one — printing 2026 on every divider all year is noise. The reversed list is taken once into a val rather than re-derived per item: asReversed() is a view, and indexing it inside the item lambda to find the neighbour is how a list like this quietly becomes quadratic.

From e519c86e9a232e47d5cb104d7f68e36b9fd5f6b3 Mon Sep 17 00:00:00 2001 From: Vitor Pamplona Date: Wed, 23 Sep 2026 22:34:19 -0400 Subject: [PATCH 089/148] fix(cordn): a coordinator timeout no longer ends sync for the session MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `CordnSyncLoop` rethrew every `CancellationException` so that stopping the loop would actually stop it. But `TimeoutCancellationException` is one, and both coordinator calls throw it: `msg_fetch_many` when the RPC budget runs out, `msg_sub_many` when its total-time budget does — the latter being the normal way a subscription ends. So the first 20-second coordinator hiccup ended `run()` outright. The job completed, the state stayed `CatchingUp`, the backoff never ran, and no cordn message reached the account again until the app was restarted. From the UI it was indistinguishable from a quiet group. Caught on the tablet against the cordn.net coordinator: one `msg_fetch_many` timeout at launch and the room stayed empty in both directions for the rest of the session. With the fix the loop reports `Retrying(attempt=1, inMs=1000, …)` and keeps trying. Now only *our* cancellation ends the loop; a spent subscription budget is absorbed where it happens, because re-opening the stream is the loop's job rather than an outage. The existing test only covered a fake that returned normally on timeout, which is not what the real one does. A coordinator that has stopped answering also logged nothing anywhere, so `CordnRuntime` now warns once per retry state — the rooms being silently frozen was most of the time this took to find.

A rule says "something else follows" without saying what, which on two of these screens is the whole problem: - Migrate is two devices' jobs and only one of them is yours today. Doing the wrong one hands your account to another phone. "Move off this phone" and "Take over from another phone" are now boxes with names rather than halves of a page. - Coordinators reads as three answers: what you use, what is on offer, and the manual escape hatch. Pasting a 64-character key belongs last, as the fallback it became once discovery went in above it. - Backup's passphrase governs both export and restore. It sat above two unrelated-looking blocks and never said so; it is its own section now. - The link screen separates asking from answering. - Key packages gets one section rather than one per coordinator, because SettingsSection titles come from a StringResource and a coordinator's label is runtime text. Its dividers move inside and are drawn between peers rather than after the last one, which used to rule off to nothing. SettingsFormBlock is the one new piece: the section card has no padding of its own, by design, because it is built for rows like SettingsItem that carry theirs so a divider can run edge to edge. Form content needs that inset back, and one helper keeps five screens identical to each other as they change. Two strings retired: the in-body "Add a coordinator" and "Coordinators announcing themselves" titles are section headers now.

It did not: `persistAll` suspends, and a suspend call in a cancelled coroutine throws before it writes anything. Cancellation is also the normal way this ends — CordnSyncLoop cancels the subscription whenever the group set changes — so the case the `finally` was written for was the one case it never served. `withContext(NonCancellable)` fixes it. That alone broke two CordnRuntime tests, and rightly. `CordnSyncLoop.stop()` was `job?.cancel()` with no join, so it returned while the loop's `finally` blocks were still running. `importArchive` stops the loops, deletes the account's directory and restores from the archive — and a persist that landed a moment late wrote a group back onto disk after the delete, which the restore then read in again. That is exactly the merge importArchive exists to prevent, and `adoptMigration` had it too. stop() is suspend now and does `cancelAndJoin`; CordnRuntime.stop() already suspended, so nothing else had to change. Nobody had noticed the missing join because the persist it races was silently failing. Making the write survive cancellation is what made the race reachable. The test needed two goes to be worth anything. The first version passed against the mutant: `send()` already persists, so the cursor it asserted on was in the store before the subscription ran, and the fake returned normally so no cancellation ever landed mid-subscription. The second still passed, because InMemoryCordnGroupStore's methods are `suspend` but never reach a suspension point — and cancellation is only observed at one. It takes a store whose writes actually suspend, like the file-backed one, and a coordinator that hangs after delivering. With both, removing NonCancellable fails the test.

That is a wall-clock snapshot with nothing to invalidate it, and every separator keeps its own, so they can disagree: the one composed before midnight goes on saying "Today" while the new day's says it too. Seen on the tablet — one room, two "Today" dividers, the older one over yesterday's messages. `today` is now read once per room from a state that re-reads the clock, and passed down. It polls rather than sleeping until the next midnight, because a device clock does not only advance — it is corrected, and this tablet jumped nine hours in one step. Re-assigning an equal `LocalDate` is not a change, so a quiet minute costs no recomposition.

It drew a flat Column per message, which meant no bubble, no side by author, no grouped corners, and — the part that actually breaks muscle memory — a plain tap that opened the action sheet, where every other chat reserves tap for nothing, long-press for the menu, double-tap for a reaction and a horizontal swipe for a reply. CordnMessageRow now calls ChatBubbleLayout and fills its five slots from the envelope and the annotation fold. The gesture vocabulary, the grouped bubble shapes, the press scale and the swipe-to-reply affordance all come with the layout. The reason cordn had forked in the first place is real but narrower than it looked: the shared slot *contents* (ChatReactionChips, ChatMessageActionSheet, ChatMessageFooter, DrawAuthorInfo) all take a Note, and a Note comes from LocalCache, which a cordn room may never enter. ChatBubbleLayout itself names neither — it is pure slots over primitives, so the layout was always shareable. Four primitives underneath it were Note-free too, just private. They are now internal and cordn calls them directly rather than restating them: - ReactionChipView / ReactionChip — the engagement strip, which brings the "you reacted" highlight the cordn chips never had. - ActionTile / TileRow / SectionDivider — the sheet is icon tiles now instead of four rows of plain text. - CHAT_GROUP_WINDOW_SECONDS — cordn had invented a 5 minute window against the shared 10, so bursts broke in different places in the two chats. Two small extractions were needed: ChatChipFlowRow out of RenderChatReactionChips, and jumboEmojiFontSize out of RenderRegularTextNote. Both are lifts, and the visibility widenings are one-word changes, so the DM and Marmot paths render exactly as before. Two gaps this closes were missing rather than differently styled: - Messages now carry a timestamp. The room showed no per-message time at all, only day separators, so nothing said when anything was said. - Grouping now yields real ChatGroupPosition values, so a burst squares off its corners instead of only hiding the repeated author line. cordnGroupPositionFor is pure and easy to get backwards in a reverse-laid-out list, so it is tested by the ends of a run by name. Mutation-checked: inverting TOP/BOTTOM, restoring the old 5 minute window and dropping the midnight check each fail exactly one test. Known gaps, unchanged by this: cordn has no retract annotation, so the strip cannot un-react (a chip long-press does nothing rather than re-sending), and there is no "who reacted" detail sheet.

Every one reads as "nothing to do" and behaves as "the attach button does nothing at all" — the picker closes, the spinner ends, and no message and no error appear. The `attachError` banner added earlier could not fire, because nothing threw. The fourth is the one that matters: `CordnMediaService.upload` returns null precisely when the account has no Blossom server, which is a setting the person can change and the only failure here that is entirely actionable. Each is now a `CordnAttachmentException` carrying a reason, and the catch that sets the banner also logs — a failed attachment previously left no trace anywhere, in the UI or in logcat. Not a reproduction: on the tablet the system picker returned RESULT_CANCELED on every attempt, so no file ever reached `sendAttachment`. This is the silent path closed by reading, not a bug observed in the field.

Composer, now on the same field every other chat uses: - ThinPaddingTextField + ThinSendButton inside EditFieldModifier. - ShowUserSuggestionList for `@` autocomplete. This closes a half-built feature rather than restyling one: cordn already parsed mentions, rendered them as names, and tinted a message that named you — but the only way to enter one was to type `nostr:npub1…` by hand. Room members rank first and the shared list badges them "in this chat" for free. - MentionPreservingInputTransformation, so an IME cannot rewrite half a bech32, and UrlUserTagOutputTransformation, so a mention reads as a name while you type it. Both match on `@`|`nostr:`, so they work on cordn's URI form unchanged. - onContentReceived, so a GIF keyboard or a paste takes the same encrypted-upload path as the file picker. Mentions insert the resolved `nostr:` URI, via a new forceNostrUri flag on UserSuggestionState.replaceCurrentWord (default off, so every existing caller is untouched). The `@npub1…` short form is only half a mention: it relies on a send-time tagger to rewrite it and emit the `p` tag. cordn has none — content goes into a sealed envelope verbatim and its reader parses `nostr:` URIs out of that — so the short form would have shipped as literal text and mentioned nobody. commons owns the draft and may not depend on Compose UI, so it cannot hold a TextFieldState. The field owns text and selection; two effects keep it equal to `room.draft`, each guarded on inequality so neither direction bounces off the other. The screen's three external writes (clear on send, restore on failure, load a message to edit) all land through it. Send passes the field's own text rather than letting the screen read `room.draft`, which settles a frame later. Screen, now on DisappearingScaffold(isInvertedLayout = true, allowBarHide = false) like every other chat screen. The bare Scaffold provided neither of the two things it brings: the bars' scroll behaviour, and the IME inset — without which the composer sat under the soft keyboard. allowBarHide is false to match the others; chat screens in this app pin their chrome. Also: the top bar had no back button at all. It has one now.

A quote whose target is older than what is loaded flashes nothing rather than scrolling somewhere arbitrary. **Who reacted.** Long-pressing a chip opens the senders per emoji. The fold keys reactions to a set of pubkeys, so the sheet is the whole truth the room holds — there is no separate receipt and no count that could disagree with the list under it. **Unread divider.** From a cursor snapshotted when the room opens: markRead() runs on open, so a divider read from the live cursor would erase itself at the moment it became useful. Own traffic is excluded, to match what unreadCount already counts — a message of yours echoing back is not news. It draws below the day separator, since in a reversed list the later-emitted row draws higher. **Faces and a member count in the top bar**, with the whole title as the way in to group info, as in every other group chat. **A confirm step before sending a file.** Attaching was irreversible the instant the picker closed: no preview, no caption, no way back from the wrong file — and a cordn attachment is encrypted, uploaded and announced to the room in one action that cannot be recalled. The dialog previews images (bounds-first subsampled decode, on IO), takes a caption that rides as the message's own content so an attachment with something written about it is one message rather than two, and holds itself open on failure so retrying is one tap rather than the picker again. Its progress bar is indeterminate on purpose: the upload is a single suspend call that encrypts and posts and reports nothing in between, so a percentage would be invented. A stage string written for a two-phase label was dropped rather than wired to a phase that isn't observable. It also fixes the filename. `uri.lastPathSegment` is a document id on a content:// URI, not a name — it is what every cordn attachment has been named. The dialog resolves the real one through OpenableColumns, off the main thread, and hands it to the upload. Left alone deliberately: zaps and the shared note-action inventory need a Note, which a cordn room may not have. Un-reacting still needs the reaction's own envelope id, which the annotation index does not keep — protocol work, not UI.

From 50184ed6feec077b03c65df655608cd0047be4a3 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 24 Sep 2026 14:05:49 +0000 Subject: [PATCH 097/148] refactor(cordn): stop duplicating three shared chat components MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An audit of what the cordn chat still defines for itself turned up three components it was reimplementing rather than reusing. One of them I had written two commits earlier, which is the more embarrassing half. **The upload dialog.** ChatFileUploadDialog has zero Note/LocalCache references and is used by the DMs, Marmot, Concord, minichat, the public channels and Nests — every upload surface except cordn, which had CordnAttachmentDialog instead. Mine was also worse: a caption and nothing else, against the shared one's caption, media-quality slider, metadata stripping and server picker. Marmot already proved the pattern works for a surface with its own encrypted pipeline — it passes `upload = { MarmotFileUploader(...).uploadMip04(viewState = state, …) }` — and cordn now does the same with CordnMediaService behind it. The duplicate is deleted. cordn cannot go through UploadOrchestrator like the nostr surfaces: its `imeta` tag carries the hash of the *plaintext* and a per-file key, which the orchestrator neither produces nor surfaces. So the dialog's two byte-level choices are applied in sendAttachment against the same helpers the orchestrator uses — compressIfNeeded for the quality slider, MetadataStripper for the strip switch — and the encryption and upload stay where they were. The sensitive-content switch is the one control with nowhere to go: cordn tells its blob host a fixed set of constants on purpose, and its `imeta` tag has no field for a warning. Rather than leave a switch that does nothing, the dialog takes `showContentWarning`, defaulting true, in the same shape as the `isNip17` gate already beside it. CordnMediaService.upload gains a server parameter, defaulted to the account's, so the dialog's spinner actually selects a host. **ChatDivisor.** The day separator and the unread line were hand-rolled Row + HorizontalDivider + Text at a different type scale from every other chat's date divisor — the exact mismatch this branch set out to remove, reintroduced. Both now call the shared one, which takes an optional tint (Unspecified = today's behaviour) so the unread line can carry the accent without a second component. **VoiceMessagePreview.** Recording sent the moment you released the button: no playback, no re-record, nothing to undo — hard to get right first time and impossible to take back. The shared preview the post and voice-reply screens use now sits above the field, and the text beside it rides along as the note's caption.

Three of these are real user-facing defects in code added over the last four commits. **Crash: sending an emptied gallery.** The upload dialog lets you delete what you picked, and deleting the last item leaves an *empty* multiOrchestrator, not a null one. `canPost()` only checked non-null, so Send stayed live with nothing to send; cordn's uploader then indexed item 0 and threw IndexOutOfBounds. canPost() now checks the size, which fixes the live button for every caller — Marmot and the rest silently posted nothing in the same state — and cordn checks again where it indexes. **Sending the same file twice.** cordn never started the upload tracker, and the dialog's Send button reads canPost(), which is only false while that tracker says an upload is running. So the button stayed live for the whole upload and a second tap encrypted, uploaded and posted the file a second time. Started now, and finished in a `finally` — not only on success, or a failed upload would leave the dialog's button dead forever. **Plaintext attachments left in the cache.** Compression and metadata stripping each write a new file, and both hold the attachment in the clear. UploadOrchestrator deletes them in a `finally`; the cordn path never did, so every attachment left an unencrypted copy of an end-to-end encrypted message on disk. Deleted now, through the orchestrator's own helper (made internal rather than copied), which no-ops on the user's own file. **Plaintext audio left in the cache.** Same defect, other path: the recorder writes to cacheDir and sendVoiceNote deletes the file after sending, but a note recorded and then abandoned — screen closed, room switched — never reached that. A DisposableEffect deletes it now. This one arrived with the voice preview, which is what made a recording outlive the tap that made it. **Stale suggestion list.** onTextChanged only fires for typing, so a list left open by a half-typed "@na" survived the field being cleared on send. Reset alongside every external write to the draft.

The envelope already has +`toJson()`/`encode()`/`decode()`.

Crash between the two and the message is on disk while the +cursor still points before it: the next `catchUp` re-delivers it and dedup drops +it. Do it in the other order and the message is gone forever, with no way back. +This is the one invariant a reviewer should check first. + +### Dedup + +Marmot dedups on whole-entry string equality via `EncryptedAppendLog.contains`. +That is not enough here: the same message re-delivered after a crash carries the +same envelope but the entry string is only equal if the cursor matches too, and +`Ingestion` can legitimately hand back a different cursor. Dedup on +`envelope.id`, using an in-memory `Set` per group built at load — cheap, +and the log is already read in full on open. + +### Where it is read + +`CordnRuntime.restoreRoomState` loads draft + read position when a screen opens +a room, deliberately: its KDoc notes that doing it at login would read state for +rooms nobody opens. + +The inbox preview breaks that symmetry — it needs `_newest` for every room +*before* any room is opened.

Fixes "No messages yet" without touching the logs. +- **full log**, read on room open, hydrating via `addAll` so the existing + `recompute`/annotation fold runs exactly as it does for live delivery. + +The summary is written on the same beat as the append. + +### `EncryptedAppendLog` placement — needs a decision + +`CordnIndependenceTest` forbids cordn importing anything whose import line +contains "marmot". The log currently lives in +`commons/.../commons/marmot/EncryptedAppendLog.kt`, so cordn cannot use it where +it is. + +It is, however, entirely protocol-neutral: it takes `encrypt`/`decrypt` lambdas +and stores opaque strings. Nothing in it knows what Marmot is. + +- **A — move it** to a neutral package (`commons/.../store/`), update Marmot's + import. One implementation, one file format, one migration path. Touches a + Marmot file (import line only, no behaviour change) and *improves* + independent-deletability: neither feature owns the primitive any more. +- **B — duplicate it** into a cordn package. ~400 lines of subtle framing, + folding and legacy-format migration, copied, free to drift. +- **C — whole-blob rewrites** with cordn's existing `atomicWrite` pattern. O(n) + bytes per send. This is the cost the append log exists to avoid. + +**Recommend A.** The guard's own KDoc draws the line at "marmot-named code" — +the coupling it exists to prevent — and a shared neutral primitive is not that. +Worth Vitor's sign-off before it happens, since it edits a Marmot file. + +### Backup and migration — needs a decision + +`CordnBackup.Archive.Group` carries coordinator, gid, state, cursor and +joined-via-request.

So a relaunch opened every room empty and no amount of syncing refilled it: the one handle to history had already been spent. Rewinding it would not have helped either — both seal keys are epoch-derived, so the copy the coordinator still holds cannot be opened once the group has ratcheted. Ingestion is the only moment the message is in the clear. **EncryptedAppendLog moves to a neutral package.** It takes encrypt and decrypt lambdas and stores opaque strings; nothing in it knows what Marmot is. It only lived under `marmot` because that is where it was written first, and the independence guard reads that as a dependency, so cordn could not touch it. Now `commons.storage`, used by both, owned by neither — which makes the two features more separable, not less. Marmot changes by one import line. **The write.** `CordnDeliveredMessageCodec` stores the envelope plus its cursor: the cursor is the coordinator's sequence, which the room orders on and the unread divider compares against, and `created_at` is the sender's clock, which is a claim. `FileCordnGroupStore` appends a segment per message rather than rewriting the conversation, so receiving costs the same on message ten thousand as on message one. **The ordering is the correctness property.** `persist` writes messages *before* the cursor. Crash between them and the message is on disk while the cursor still points before it: the next catch-up re-delivers it and dedup drops it. The other order loses it permanently. That is why the write lives next to the cursor write rather than at the call sites. Dedup keys on the envelope id, not the stored entry: a re-delivery carries the same envelope with a different cursor, so the bytes differ while naming one message. **The read, in two parts.** The conversation loads when a room opens, through `addAll`, so the annotation fold and ordering are rebuilt by the same code that handles live delivery. A one-entry summary per group loads at login for the inbox line — which is why every cordn room read "No messages yet" after a relaunch however much had been said. Deleting a group takes the log and the summary with it. History that outlived its MLS state would be the plaintext of an end-to-end encrypted conversation left behind after the key that read it was destroyed. Mutation-checked: inverting the write order, dedup'ing on the whole entry instead of the id, and forgetting to drop history on delete each fail exactly one test and nothing else. Not yet carried into backup or device migration — the plan (commons/plans/2026-09-24-cordn-message-store.md) recommends migration yes, backup no, and that is still an open call.

Every other piece has a second source: MLS state re-derives from the coordinator's stream, a KeyPackage can be republished. A cordn message has none. It is readable exactly once, at ingest, because both seal keys are epoch-derived and the cursor this very document carries has already advanced past everything behind it. A device seeded without the messages arrives holding every group and no conversation, permanently. Carried as `amethystMessages` on the group document, beside the other additive `amethyst*` fields, so an older reader ignores it rather than failing. Bounded per group by a byte budget, newest first. These blobs go to hosts whose limits we do not know, and a handoff that fails outright because one group is chatty is a worse outcome than one that carries a deep but bounded history. Budgeted in bytes rather than messages because a single long message can cost as much as a hundred short ones. Written before the cursor on import, for the same reason the live path writes them in that order: a seeding that saved the cursor and then failed would leave a device holding a cursor past a conversation it never wrote, with no way to ask for it again. My first version had the comment saying that and the code doing the opposite. Mutation-checked: a document that silently drops the messages fails the round-trip test and nothing else. Backup still excluded, per the plan — that call is still open.

Sent from the tablet to cordn.net, each one arrived as an empty bubble — no filename, no player, no error. Two departures from `spec/applications/encrypted-media.md`, both in this repo's own code rather than anything ambiguous in the spec: - **The file key.** §3.1 requires `MLS-Exporter("cordn", "encrypted-media", 32)` over the epoch's exporter secret. We minted a random key per file and shipped it in an `imeta` `k` field — a field §3.1 says the key is "never transmitted, never stored in". A receiver derives the key from group state, so ours had nothing it could derive. - **The version.** §4 requires `v cordn-em-v1` and says a client "MUST reject tags whose `v` field is absent". We emitted none, so a conformant client is obliged to drop the tag — which is exactly what cordn.net did. `CordnMediaTag`'s KDoc asserted that cordn had no equivalent of Marmot's `v` field and that adding one "would put a field on the wire that no other cordn client writes or reads". The spec says the opposite on both counts. The AEAD and the AAD were already right, so this changes the key source, drops `k`, and adds `v`. **The durability cost is real and is the spec's intent.** The old design was chosen so an attachment would outlive its epoch; the spec instead wants the key to rotate "with each MLS epoch advance, inheriting the forward-secrecy and post-compromise-security properties of the group". Since `exporterSecret` answers only for the current epoch, media sent before a Commit cannot be re-opened yet. Keeping it readable is a matter of caching the derived key per epoch locally — which changes nothing on the wire, unlike the approach it replaces. Three tests asserted the old behaviour, including one named "an attachment survives the epoch it was sent in". They are replaced by tests that the tag carries `v` and never a key, and that a missing or unknown version is rejected. Also: sendVoiceNote still had the bare `?: return`s that sendAttachment lost last commit, so a voice note could fail in silence the same way.

So a voice note that the composer had just shown as a waveform arrived in the bubble as a file to open, and the one chat with encrypted media was the one chat whose media did not look like the app. `CordnMediaCipher` is the missing piece: cordn's codec as a `NostrCipher`, the same shape as `Mip04Cipher` and `EncryptedMediaV2Cipher`. Registered against the blob URL in the encryption key cache, `EncryptedBlobInterceptor` decrypts the download in flight, so `CordnAttachment` can hand an `EncryptedMediaUrlImage`/`Video` to `ZoomableContentView` and inherit the zoom dialog, the pager, the content-warning gate, thumbhash backdrops, and the square audio player with its visualiser — the last of which is what makes a voice note play in place. Audio reaches the video branch deliberately: `mediaSizingModifier` already special-cases audio to a null aspect ratio so the inline player can size itself, so routing through it is how cordn gets the same player Marmot has. **This changes when a blob is fetched.** The old code waited for a tap, on the argument that fetching tells the blob host a particular person opened a particular message. The concern is real and a cordn-only gate was the wrong answer to it: auto-loading media is an app-wide setting the shared renderer already honours, and every other encrypted chat routes through it. `toImageBitmapOrNull`, `VoiceNotePlayer` and the two strings they needed go with them. Also, the composer's leading icons: they were bare IconButtons in an unpadded Row, so each kept its full 48.dp touch target with nothing pulling the row in, and they sat further from the edge and further apart than every other chat composer. They now use the frame `MarmotGalleryLeadingIcon` uses — 4.dp either side, placeholder tint — and the mic is tinted to match, red only while it is recording.

Sending a message did not move the view onto it. The shared feed scrolls to the newest row only while the reader is already at the bottom, which is right for someone else's arrival and wrong for your own send: scroll up to read history, type, send, and the message you just wrote lands off-screen below. Your own message now always pulls the view onto it, in every chat. That effect lived inline in ChatFeedView, so the cordn screen — which renders its own LazyColumn because cordn messages are not Notes and never enter LocalCache — had inherited the shared bubble, chips and composer but none of the container's behaviour, and had no auto-scroll at all. It is now a shared AutoScrollToNewest that both call, along with the feed's contentPadding and the per-item animateItem, so a sent message enters rather than appears. Attaching animateItem meant wrapping the cordn row in a Column, which is one placeable where three siblings were. reverseLayout mirrors each of an item's placeables about the main axis — which inverts siblings but does not reach inside a layout — so the day and unread headers move ahead of the bubble to keep drawing above it. Dropped the divider between the conversation and the composer: no other conversation screen has one. The pinned ribbon keeps its divider, which matches RelayGroupPinnedBar. Separately, a voice message in any chat played in the generic media player rather than the waveform UI it was previewed with. The audio-only short-circuit had a single caller, the main feed's note renderer, and chat bubbles never ran it. The chat bubble now checks the same imeta, matching the DECRYPTED content because a chat note's own content may still be sealed.

The check is RichTextParser.isAudioContent, already the app's answer to this question, so a declared MIME wins and the extension is only the fallback. Each keeps its keyCache registration ahead of the branch, so the blob still decrypts by URL exactly as it did on the video path. Cordn could not reach that player at all: it wanted a Note, for an author name, a nostr URI and a hashtag row, and cordn messages never enter LocalCache. Split out RenderAudioWaveformPlayer, which is the player without any of that, and left the Note-shaped overload as that plus the hashtag row — the same Note-free extraction the chat bubble already went through. None of the three encrypted formats carries a waveform, so the bars are absent and the transport is not, which is still the voice UI rather than a video one. The DM header now reads a `waveform` tag if a sender attaches one, covered by tests including that an unparseable tag is no waveform rather than a broken message.

The quoted message a reply answers was a bespoke accent-bar card — the one place in the app where a quote did not look like a quote. It is now the same ChatBubbleLayout in innerQuote mode that Marmot, Buzz and the DMs use, so the quoted author's bubble shape, tint and coloured name all match. The enclosing bubble's fill is threaded in as parentBackgroundColor, which is what the shared layout composites the nested bubble over; without it a quote is tinted against the screen rather than against the bubble holding it. The composer's reply preview renders through the same composable, so it follows for free. The shared layout does not gate long-press on innerQuote, so a quote bubble with no menu would have swallowed the gesture. It gets the two things that mean something on a preview: go to the message, and copy its text. Double-tap sent a hardcoded thumb. It now sends the account's first configured reaction, which is what reactToOrDelete does everywhere else — and what cordn's own action sheet already read, so the screen disagreed with itself. Tapping the timestamp flipped relative/absolute here and opened delivery detail in every other chat. It now opens a details sheet — absolute time, the cursor the coordinator filed the message under, and which coordinator — and your own messages carry an accepted tick beside the time. Cordn has one hop where the shared ticks have a relay set, and post() returns the cursor before anything enters the room, so the tick says exactly what it can stand behind.

The sheet now splits the way the shared one does: the actions native to this chat — reply, pin, edit, delete — stay up front, and the generic what-you-can-do-with-any-message inventory moves behind the Show More toggle, which is `MoreActionsToggle`, now internal rather than private so cordn reaches the same control instead of drawing its own. Behind it: copy text, and share. Share hands the text to the system chooser rather than a nostr address, because a cordn message has none — it lives on a coordinator, not a relay, so there is no URI that would resolve for whoever receives it. Delete asks first, gated on the same hideDeleteRequestDialog setting the shared sheet uses, so someone who has already opted out of being asked is not asked here either. The wording is cordn's own: the relay copy the shared text describes is not what happens, and what does happen is that the coordinator keeps the ciphertext. Two actions the shared sheet has are deliberately still absent. Report needs a note on a relay to report, and quoting needs an address that resolves — neither exists for a message that only the group can decrypt. Block is the one worth naming: `hideUser` would mute someone app-wide while their cordn messages kept arriving, because nothing in a cordn room consults the mute list, and a control that looks like it silences someone here but does not is worse than no control. The top bar's action icon is Marmot's GroupAdd rather than Info — same screen, and adding someone is what people open it for.

The attach button is now the app's own SelectFromGallery, so this composer offers the same affordance, tint and multi-select as the DM and Marmot ones instead of a bare file dialog. Each pick is its own encrypted upload and its own message, which is what the send path already did. NOTE, because it is a capability change and not only a visual one: the old button was GetContent("*/*") and could attach any file. SelectFromGallery is images and video. The encrypted-blob path still takes whatever it is handed, so restoring arbitrary files is a one-line change — say so and I will put it back beside the gallery. `:shortcode:` completion, which the DM and Concord composers have and this one did not. It inserts the emoji's URL rather than its shortcode: a shortcode only resolves for a reader who also received the NIP-30 `emoji` tags, and a cordn message carries none, so everyone else would have read a literal ":shrug:". The same reason mentions here are forced to `nostr:` form. Typing routes to one list or the other by the word's first character, and both close when the draft is replaced from outside. A room with no messages now shows the shared EmptyState rather than blank space. There is no loading or error branch to match the shared feed's: the session opens behind restoreRoomState, and a room that cannot reach its coordinator says so on the action that needed it, through the send banner. That banner stays as it is, which is the one place this list ends in a deliberate difference rather than a change: Marmot reports a failed send with a Toast, cordn with a line above the composer that does not disappear on its own. Converging them means changing Marmot, and the persistent one is the better of the two.

Message bodies went through a local MessageBody: plain Text, plus a FlowRow of mention spans. So a link, an image or video URL, a hashtag, a `nostr:` entity, markdown, and — since the composer started inserting them one commit ago — a custom emoji's URL all arrived in the bubble as raw text. Nothing about it needed a Note. TranslatableRichTextViewer, which is what every other chat's bubble reaches through RenderRegularTextNote, takes a String, a background colour and an id. Cordn had the first two and the third all along; the bubble's colour was already threaded through for the quote bubble. Two arguments are deliberate. `tags` is EmptyTagList: a cordn envelope's tags are cordn's own — §4 media, references — not NIP-92 or NIP-30, so passing them would ask the viewer to read them as something they are not. `canPreview` is true, which is what an unblocked note gets in a NIP-17 DM, equally end-to-end encrypted; it does not force a fetch, because whether a preview is actually loaded remains `automaticallyShowUrlPreview`, the account's own Tor-aware setting. The quoted-message preview keeps its two-line plain Text. It is a deliberately compact summary and the viewer does not clamp to a line count. CordnMentions.segment now has no caller in the UI. Left in place: it is a tested commons helper, not dead screen code, and the mention highlight still uses CordnMentions.mentioned.

We treated admin_pubkeys as presentation metadata and left authorizeCommit at the default. The class KDoc said "neither the spec nor the reference coordinator restricts who may commit", which was the wrong component to look at: the coordinator cannot restrict it, the client is where it happens, and the reference client does. Accepting a commit the rest of the group rejects forks the epoch, and MLS does not recover from a fork. authorizeCommit now implements that rule. The engine calls it in both directions, so one check covers both. The gate is the reference's three proposal types and nothing else — an Update, a SelfRemove or a PSK from any member stays allowed, so nobody is trapped in a group they may not leave. Being stricter would fork the epoch in the other direction. An empty admin list stays egalitarian: the gate opens rather than closes. One trap worth recording, because it would have inverted the check rather than disabling it. Marmot's credential holds the account key as raw bytes, so GroupView.memberIdentityHex is the pubkey. A cordn credential holds it as 64 ASCII hex characters, so the same accessor returns 128 characters that are never a pubkey — comparing an admin pubkey against it matches nothing and rejects every commit in a group that names admins, which would have read as "admins can never commit" rather than as a decoding bug. The comparison therefore happens in credential-bytes space, mapping the admin list forwards rather than decoding a leaf backwards, which also keeps untrusted bytes out of the decoder. The test for it fails if that mapping is removed. Groups Amethyst creates are all egalitarian today, so this changes nothing for them; it matters for a group created elsewhere that names admins.

It refuses to remove YOU, as the reference does: cordn has no self-removal, and committing your own Remove advances the group into an epoch whose keys you no longer hold. updateGroupMetadata replaces the cordn_group_metadata extension, which is how a group is renamed, re-described, re-iconed — and how its admin list changes, since that list lives in the same extension. A GroupContextExtensions proposal replaces the WHOLE extension list, so every other extension is kept and only 0xC04D is swapped; sending the metadata alone would drop required_capabilities and leave a group whose next commit peers reject. Verified by a test that compares the extension-type set before and after. Neither function checks admin rights itself. authorizeCommit already refuses to build those commits for a non-admin, so the check cannot be forgotten at a call site or bypassed by a new one. pendingJoinRequests now asks only for groups this account administers, which is what the web client's fetchJoinRequestsForAdminGroups does. Accepting a request is an Add commit, so in a group that names admins a non-admin was being offered people it could only fail to let in. Egalitarian groups name no admins and are all still included. Nine tests. One is worth reading: "a non-admin cannot remove anyone" first failed during its own setup, because a group created with admins = [bob] refuses alice's invite too. The gate firing there was correct but tested the wrong call, so the test now hands admin over after inviting — a sequence that actually happens.

Two screens. Creating a group now offers the choice rather than describing it. The web client picks admins out of the members being added; this screen adds nobody — a cordn group starts with its creator and invites follow — so at that moment the only admin there could be is you, and the choice collapses to one switch. The rule the web client states holds either way: choosing any admin at all must include yourself, or the group is born unadministrable. That also corrects a string. The old note said cordn "has no way to promote an admin later", which updateGroupMetadata has just made false in both directions: an egalitarian group can name admins, and an administered one can hand the role on. Group info gains the two controls and the gate. Members carry a remove button for admins only, never against yourself — cordn has no self-removal and the manager refuses it, so offering the button would only be a way to be told no. Edit details renames and re-describes, carrying the admin list through untouched: the extension is replaced whole, so a save that dropped it would quietly turn an administered group egalitarian, which nobody could undo from inside an egalitarian group's own rules. The removal confirmation is a plain AlertDialog rather than the shared quick-action one, which offers "don't ask again" — not something to nudge anyone into for an irreversible removal. Join requests are now shown only to admins. The manager already asks the coordinator only for administered groups, so a non-admin would otherwise read an empty list as "nobody has asked" rather than "these are not yours to answer". Correcting something I said earlier in this work: the info screen already showed per-member admin badges and an admin count. What it lacked was the gating and the controls, not the display.

The admin list is a label, not a lock." That stopped being true when CordnGroupPolicy.authorizeCommit started refusing add, remove and group_context_extensions proposals from non-admins in both directions, and it sat directly under a section that is now gated on administering the group -- so the one line explaining the section contradicted the reason it was on screen. Renamed the key rather than rewriting its value, so translators re-translate instead of inheriting text whose meaning inverted. It existed only in the source locale, so nothing is lost. The section's KDoc argued at length for *not* gating on admin and cited a CordnGroupPolicy passage that no longer exists. Rewritten to state why the gate is there: a non-admin pressing accept would build a commit the rest of the group drops on receipt, so offering the button would be the misleading option, not the honest one.

Nothing carried them any further: `CordnMediaTag` had no field for them, so they were dropped at upload and the sender's own voice note came back with no bars. They were not the only hint missing. `spec/applications/encrypted-media.md` §5 defines `dim`, `blurhash`, `thumbhash` and `alt` as optional display hints "passed through unchanged". We declared two of them and wrote neither: the one production caller of `build` passed no dimensions and no blurhash, and `thumbhash` and `alt` did not exist. So an image arrived with no aspect ratio to reserve — the bubble resizes when the picture lands — and no description for anyone reading by screen reader. The tag now has all four plus `waveform`, parses them back, and `upload` takes them. The voice path passes the amplitudes it already had. `waveform` is NOT in §5. It is written as one more display hint, in the slot the spec describes as passed through unchanged, so a client that does not know it ignores it. That is a smaller liberty than the `k` field this codec used to carry — that one replaced a required derivation and broke decryption outright; this one is additive and costs an unaware reader nothing. Kept out of the AAD deliberately: it is a hint about the file, not a claim the ciphertext is bound to. **And when nobody carried one.** `RenderVoicePlayer` drew bars only if it had amplitudes, so every encrypted voice note in the app — MIP-04 and encrypted-media-v2 define no waveform field at all — played as a bare black bar that reads as a broken video. It now falls back to a placeholder, which fixes DMs and both Marmot paths as well as cordn. The placeholder has to vary. `AudioWaveformReadOnly` normalises amplitudes onto the bar height, so a constant list has no range to normalise and every bar collapses to the minimum: a flat 0.35f drew a dotted line. It is a short pattern tiled across the width — enough relief to read as audio, regular enough that nobody mistakes it for a measurement of their own recording.

Nothing about the drawn shape could correspond to speech at a resolution anyone would recognise. It now samples ten times a second. **The first sample was taken before any audio existed.** `maxAmplitude` reports the peak since the previous call, and the call made immediately after `start()` covers a window in which the encoder has captured nothing — it answers 0. Every recording therefore opened with a bar of silence that is not in the audio, which is exactly the "additional silence before the wave" this was reported as. The loop now delays before its first read. Sampling finely would make a long recording a long list, and these travel inside events and `imeta` tags, so `stop()` reduces to at most 100 points by averaging. Averaging rather than taking every Nth: one loud frame should not stand for a whole bucket, and a test covers a quiet recording with a single burst in it to keep that honest. Also corrects a claim I made in `CordnMediaTag` last commit: the waveform floats are on `maxAmplitude`'s own 0..32767 scale, not 0..1. That is already the app's convention for kind-1222 — `VoiceAnonymizer` multiplies back up by 32768 to match it — and the renderer normalises whatever range it is handed, so the doc was what was wrong, not the data. Verified on the tablet, three renderings side by side in one room: a note with no waveform draws the placeholder, one recorded at the old rate draws coarse blocks, and one recorded now draws a dense shape identical to the composer preview it came from.

Measured against MarmotGroupInfoScreen, which is the app's norm for this page: - The coordinator key (64 hex chars), the group id and the MLS epoch were the first thing on the page. They are what you need to file a bug or tell two devices apart, and nothing you need to read a message, so they move into a collapsed "Technical details" section beside the exposure card -- the page's other protocol-literate block. Selectable when open, since the only reason to look at them is to copy one somewhere else. - "Members: 4" sat directly above a list of four members. The count becomes a header subtitle, as Marmot does it. - "Admins: 2" sat directly below a roster that already badges both of them. Dropped. The egalitarian case was the one thing that row uniquely said -- and it is permanent, so it is worth saying -- and it survives as a caption under the Members heading, shown only when it is true. - Editing was an OutlinedButton in the middle of the body; it is now a top-bar action where the sibling screen keeps it. The bar is factored into InfoTopBar with a slot, so the no-group state keeps the same bar. - Four dividers separated sections that mostly had no heading. Members gains one, and Share/Requests move to titleMedium to match. Also corrects the share block's "A member still has to add them", which was the same stale claim the join-requests line carried: adding is gated on being an admin once a group names any. InfoRow survives, but only inside the disclosure -- it was never wrong for one or two facts, only for four in a row.

From e26629f33edada0f693e794677b0c2a1a32cadd6 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 25 Sep 2026 13:14:23 +0000 Subject: [PATCH 118/148] fix: sort cordn rooms in Messages by their newest message A cordn room always sat at the bottom of the Messages list, under every DM and every other group chat, ordered alphabetically by row id among the other cordn rooms. The row displayed the right timestamp the whole time; only the sort could not see it. Two independent causes, either of which alone keeps the list wrong. The row had no time. inboxRow() handed the feed a plain Note, whose createdAt() reads `event?.createdAt` -- and a cordn message is an MLS envelope that never becomes an event. sortedByDefaultFeedOrder() maps that null to 0L, which is not "undated" but "last, forever". The two other event-less inbox rows already solve this by overriding createdAt() to mirror their newest message (RelayGroupServerRoomNote, ConcordServerRoomNote); cordn is the one that was missing it, so CordnInboxRowNote follows them. Nothing told the feed to re-sort. The Messages rebuild was driven off CordnGroupList.all, which re-emits only when the room *set* changes: a message for a room the list already holds returns early from getOrCreate and never reassigns it. So the inbox ordered cordn rooms once, when they were joined, and never again -- the comment above that collector claimed `all` bumped on "every message that moves a room's preview", which was simply not true of the code below it. Adds CordnGroupList.revision, bumped on the set and on every message actually filed (never on a re-sync echo), and points the collector at it. Same shape as the Concord control plane's revision, and sample()d for the same reason. CordnInboxRowTest covers both halves; reverting either fails it.

So it has a kind 0 like anyone else, and the app already knows how to resolve one. The group info screen was rendering it as the hex string it happens to be stored as -- which told the user nothing and threw away a name, an avatar and a profile to tap through to, all of which the same screen was already drawing ten lines up for every member. It now uses the same UserPicture + observeUserNameByHex pair as the roster, so the profile is fetched through the normal metadata subscription and the row navigates like any other user. That also gives the exposure card the section heading it lacked: "Coordinator" now reads as who serves this group, followed by what it can see. The key stays in Technical details, relabelled "Coordinator key". The two answer different questions -- the row says who the coordinator is, the disclosure says which bytes to compare against a share ref, a device document or a log, all of which speak hex. Known gap: a coordinator with no kind 0 falls back to an 8-character prefix, where CoordinatorConfig.label or the CEP-6 announcement's surface name would read better. Left for a follow-up rather than guessed at.

A coordinator is a Nostr identity, and CEP-23 says outright that a server MAY publish NIP-01 profile metadata -- CvmKinds.PROFILE_METADATA is kind 0 for exactly that reason -- so the app can name one the way it names anybody. CoordinatorIdentity.kt now holds the one resolution both screens use: the local label first, then the profile, then the key's first characters. The label wins on purpose. CoordinatorConfig documents it as "what the user calls it. Never a claim -- a coordinator cannot prove a name", and a kind 0 is the coordinator's own word for itself exactly like the CEP-6 announcement's name, so a name the user chose is the only one here that means anything. The profile is observed either way, so the avatar loads for a coordinator the user named. - Coordinator cards gain an avatar, and "Unnamed coordinator" is gone: that was only ever true of the label, and a coordinator with a kind 0 has had a name all along. The string is deleted, since the chain can no longer reach it. The full key stays, selectable -- this is the screen where you verify that the coordinator you added is the one you were told to use, and no name can settle that. - Discovered offers gain an avatar but keep the announcement's name: in a discovery list the CEP-6 surface is the thing on offer, and both names are the server's own claim anyway. - Group info passes the label through, read from the stored config rather than from serverInfo(), which is a live MCP call over kind 25910 -- a screen that fired one on open would tell the coordinator every time someone glanced at a group (spec/00.md section 8). Not done, deliberately: falling back to the CEP-6 announcement's name for a *known* coordinator. ServerAnnouncement is a parser over a raw Event, not a registered event class, so nothing caches announcements per coordinator -- that fallback needs a new event type plus its own subscription, which is more than a naming polish should carry. Discovery remains the only place that name appears, and persisting it into the label would contradict what the label says it is.

It now names what was sent: Voice note, Photo, Video or File, chosen off the first attachment's MIME. The first one decides because a row is one line, and a message with a photo and a file in it is, to someone skimming an inbox, a message with a photo in it. A withdrawn message says so too, rather than falling through to the attachment label. **The share block printed the bech32 above the QR.** Three lines of characters that are not readable and not meant to be retyped, pushing the QR itself below the fold. Both things a person actually does with that string are still on the page — point a camera at the code, or press Copy link. Verified on the tablet: the row reads "Dr. Edo Paz: Voice note", and the share section is explainer, QR, Copy link.

That lookup had no outbox to go on, so pickRelaysToLoadUsers fell through to this account's index and home relays -- telling them the account is interested in a pubkey that CEP-6 announcements publicly identify as a coordinator. cordn's own traffic never touches those relays: it goes to config.relays over NostrClientCvmRelayPool. So showing the name and the face had quietly opened an inference channel in the one direction cordn's posture does not otherwise cover -- not what the coordinator learns, but what the user's relays learn. Opening a coordinator now fetches its kind 0 and its kind 10002 from config.relays, which is where they belong: CEP-23 says a server may publish NIP-01 profile metadata, and CEP-17 reuses NIP-65 for server reachability. With a relay list cached, UserOutboxFinderSubAssembler has an outbox for the pubkey and issues no discovery filter at all -- `if (noOutboxList.isEmpty()) return null`. The name and avatar still arrive; nothing new observes it. Relay hints alone would not have closed this. pickRelaysToLoadUsers broadens to index and home relays whenever a user has fewer than three hints, and a coordinator usually lists one or two, so the account's relays would still have been asked. The global CacheClientConnector files whatever comes back, so there is nothing to consume, and failure is silent: a coordinator with no profile is ordinary and the screens already fall back to the key. Coordinators stay searchable and mentionable. They are real npubs and that is not worth special-casing the cache for. CordnRuntimeTest gains a recording client and asserts the REQ goes to config.relays and carries only those two kinds. Adding a relay to the set fails it, and so does dropping the relay-list kind.

But it could only be typed while adding a coordinator by hand, so one that arrived from discovery, or came back with a restore on a new device, could never be named at all. That also made the label the group info screen reads permanently null for those. Coordinator cards now carry a rename action. Renaming deliberately does not go through the reopen path. The registry rebuilds the transport for a config that differs, because the transport is bound to the relays -- and that builds a new CordnGroupManager while the running CordnSyncLoop goes on holding the old one, whose scope has just been closed. A label is not part of a coordinator's address (section 8.5 makes the pubkey the identity) and nothing under CordnSession reads one -- CordnCoordinatorStore is the only reader, when it writes the list to disk -- so a label-only change now updates the config in place and publishes, and CordnSession.config is settable only through relabel(). Empty saves as no label rather than an empty one, so the display can still fall through to the profile and then the key. **The new-group screen could not find a coordinator.** It offered the ones this account already had, or a pubkey and relays typed by hand -- no way to discover one, though the settings screen has had that since discovery landed. It now has a Find coordinators button over the same CEP-6 announcement fetch, listing what it finds as further choices, each with how long ago it announced: staleness decides whether the choice can work at all, since a coordinator that announced itself and went away takes the group creation down with it. Offers this account already holds are filtered out, so the same coordinator cannot be picked twice with different relays. Looking asks relays, never a coordinator, so it costs nothing and tells the coordinator nothing. CordnRuntimeTest covers both halves of the rename: reverting the label-only path fails the test that the manager instance survives. Pre-existing and NOT fixed here, since it needs its own change: correcting a coordinator's *relays* still takes the reopen path, and CordnRuntime.loops keeps the loop built over the old manager -- so a relay correction leaves that coordinator retrying against a closed transport until the app restarts.

CordnSyncLoop captures its source for the life of the loop, and CordnRuntime only ever created a loop when there was none, so after a relay correction the loop went on polling the connection that had just been closed. That coordinator then retried forever, its rooms never updated again, and restarting the app was the only way out. The loop is now keyed to the manager it was built over, not merely to the coordinator's pubkey: a loop whose source is not the session's current manager is one the registry has already orphaned, and it is stopped before the replacement starts, because two loops on one coordinator would file every delivery twice. Its retry-logging collector was leaking across the same swap -- it was launched into the runtime scope and nothing held it -- so the handle carries that Job too, and stop()/forget() cancel it with the loop. The label-only path added alongside this means a rename never reaches here, so this is now exactly what it says: a corrected address. The fixture could not see any of it, because one stub was shared per coordinator pubkey and a reopen was invisible through it. It now records one connection per connect and counts the subscribes each receives, which is the invariant itself: a connection no loop points at is never subscribed. Reverting the guard fails the test.

The only route in was Share a link, wait for a join request, accept it -- while the chat screen's top-bar icon is GroupAdd, so the icon promised an action the screen did not offer. Adding now works the way finding a person works everywhere else in the app: ShowUserSuggestionList over UserSuggestionState, the same pair the composers and the sibling group-info screen drive, so a name, an npub and a NIP-05 address all resolve. Not a field wanting 64 hex characters. The reason a picker was originally left out -- it could only honestly offer accounts that published a KeyPackage to this exact coordinator -- is handled by saying so rather than by hiding the feature. Nothing on the device can know who did until the coordinator is asked, so the note says it before the attempt and CordnGroupManager.invite says which of the two failed after it: "the coordinator holds no KeyPackage for X" is a different problem from a name that matched nobody, and they are worth telling apart. Admins only, since the policy refuses an `add` from anyone else. Also fixes something I broke earlier in this branch. The admin actions called the manager directly, and the manager commits and posts but never touches the CordnGroupChatroom the screen draws from -- only CordnRuntime.refresh does. So a removed member stayed in the roster and a rename kept the old name until a message happened to arrive or the app restarted. invite, removeMember and updateGroupMetadata now live on CordnRuntime, each pairing its commit with that refresh the way createGroup, accept and acceptJoinRequest always have, and runAdmin hands over the runtime rather than the manager so the short path is no longer available to reach for.

A coordinator this account already uses never goes through discovery again, so its CEP-6 announcement -- the name the user most likely picked it by -- had nowhere to come from, and the display fell straight from the local label to the kind 0. The announcement now rides along with the profile prefetch that already runs when a coordinator is opened: one kind added to the same filter, against the same relays, so it costs nothing extra and still tells the coordinator nothing. It is the one of the three the cache cannot keep -- ServerAnnouncement is a parser over a raw Event with no registered event class, so nothing would have parsed or stored it -- which is why the events come back from the fetch and are read here into CordnRuntime.announcedNames. `announcedServerName` lives in commons beside the discovery that applies the same rule: newest per kind wins, because these kinds are replaceable and a lagging relay will hand back last month's name after a fresher one arrived. Shared rather than re-derived, since that is the part which is easy to get subtly wrong. The order is now label, announced name, kind 0, key prefix. The announced name goes above the profile because a coordinator added from discovery was picked by it, and having the settings screen quietly rename it afterwards would be its own confusion; both are the server's own claim, so neither outranks a label the user set. A blank announced name reads as absent so the chain can fall through. AnnouncedServerNameTest covers the rule, including the stale-relay case: replacing newest-per-kind with "last event seen" fails it.

So another member's message re-sorted Messages and your own never did -- the exact case the fix was for. The signal moves onto CordnGroupChatroom, which is the only place that sees every way its newest message can change (a filed delivery, an optimistic send, a restore), and fires only when the newest envelope id actually changes, so a reaction or an edit no longer asks the whole inbox to re-sort. The list's bump is now `update {}` rather than `value++`, because deliveries arrive off the sync loop while a send files one from the UI and a read-modify-write drops bumps under exactly that interleaving. **The announced name came from unfiltered relay output.** A REQ's `authors` is what was asked for, not a promise about what came back; discovery is safe because it groups by author first, and a flat fetch result has had no such treatment, so one relay in a coordinator's own list could pick the name shown for it -- which outranks its kind 0. `announcedServerName` now requires the pubkey and filters on it, so the rule sits with the function instead of in each caller. **Four smaller ones.** The prefetch launch is held by SyncLoopHandle so stop() and forget() cancel it; announcedNames is pruned on stop, forget and purge instead of keeping names for coordinators this account no longer has. The create-group discovery reports `unreachable` the way the settings screen already does, rather than calling a sweep where every relay timed out "nobody is announcing". A re-discovery that drops the picked coordinator no longer leaves an unexplained dead form -- the selection falls back to manual entry, whose fields appear and explain themselves. CoordinatorIdentityRow's name slot gets the RowScope receiver its callers were already relying on by accident, plus a real `trailing` slot so the rename action stops travelling through a slot called `name`. Also corrects a comment that overstated what the profile prefetch buys: it silences the outbox-discovery assembler that gates on a missing relay list, not every query about that pubkey -- UserReportsSubAssembler and UserCardsSubAssembler ask this account's relays either way. Three new tests, each mutation-checked: an optimistic send bumps the revision (reverting the room-level signal fails it), an annotation does not, and an announcement from another pubkey is not this coordinator's name.

Those messages are written for a log — they name pubkeys and gids in full, which is exactly what you want when reading one and never what you want in a chat. So somebody who searched by name, saw a face and tapped add was told "the coordinator holds no KeyPackage for 74ee1b23…" and left to work out which of those hex characters was the person. That is the same thing the group info refactor spent a commit removing from this page, and it slipped through because it arrives from a commons exception rather than a string resource. `CordnGroupException` gains a `Reason`, so the screen can branch on a value rather than search for substrings in English that is free to be reworded. Four reasons carry wording of their own — no key package, a key package belonging to somebody else, no Welcome, not a member — and the default stays OTHER so every other throw site keeps compiling and keeps showing its message. The screen adds three more cases the enum cannot cover: self-removal, which is an IllegalArgumentException from a `require`; a coordinator that does not answer, which is the commonest failure here and says nothing useful in its own words; and anything else, which still falls back to the message rather than to silence. The display name comes from the row that was tapped, because the exception only ever knows the pubkey. Every failure is also logged in full now. The banner is for the person; logcat is for whoever has to find out why. Verified on the tablet against a freshly generated key that belongs to nobody and has published nothing: "npub1wnhpkgc7…js6ksmev has not published a key package to this coordinator, so they cannot be added yet. Ask them to open cordn on this coordinator first." Membership stayed at 2 — `invite` throws before it commits anything.

The reason given for all of it was that ServerAnnouncement is a parser over a raw Event "with no registered event class, so nothing caches one". That was backwards: nothing cached one BECAUSE no class was registered. EventCache says so itself, above the group this now joins -- "New kinds without custom consume logic go in one of the two groups below -- an unlisted kind falls into the else branch and is rejected as unsupported." So the kinds are typed and listed: CvmServerAnnouncementEvent (11316) and CvmToolsListEvent (11317), both BaseReplaceableEvent, registered in EventFactory and added to EventCache's replaceable group. From there the cache does what it does for every other kind -- stores it, keeps the newest per (kind, pubkey) because these kinds are replaceable, and verifies before anything trusts it (wasVerified || justVerify) -- and the screens read the name off the cached note through observeNoteEvent, the same event-finder data source the rest of the app uses. Deleted, because the cache replaces all of it: CordnRuntime.announcedNames and its three pruning sites, announcedServerName with its hand-rolled newest-wins, author filter and injectable verify, that function's test file, and the announced-name plumbing through both screens' call sites. The prefetch stays, but only to aim the request at the coordinator's own relays -- the one thing the generic data sources cannot know until its relay list is cached. Also drops the raw hex from Technical details. A profile shows a short npub with a button that copies the full one and then the same for the nprofile (DrawAdditionalInfo); nothing user-facing in this app shows 64 hex characters, and there was no reason for a coordinator to be the exception -- the argument that refs and device documents speak hex was about the wire encoding, not about what a person should read. The nprofile earns its place here more than on a profile, since its relay hints are how a coordinator is reached at all. Still to do: CordnCoordinatorDiscovery reads surfaces off a raw sweep for unknown servers and needs relay attribution, so it keeps its own path -- and its own verification, which it still lacks.

It was the same word on every one of them, next to a Dns icon that already says this is not an ordinary chat, so it cost a line of space to tell a reader something they could neither act on nor use to tell two rooms apart. The coordinator is the useful fact. It is the one server that carries every message in the group, in order — the trade the exposure card exists to explain — and which one a room runs on is the thing worth knowing at a glance. It also puts the row in line with its neighbours: "Soapbox Community" and "Public Chat" both name the controlling entity rather than the protocol. Reuses `coordinatorDisplayName`, so the row resolves a name the same way the settings screen does and in the same order: the user's own label first, then the CEP-6 announcement, then the kind 0, then the key. `ChannelTitleWithLabelInfo` gains an overload taking a plain string, since a coordinator's name is a value rather than a string resource; the resource overload delegates to it and every other caller is untouched. The pill no longer says what kind of room this is, so the content description does: "cordn group, carried by X". It was the pill's text before, and losing it for a screen reader would be a real cost rather than a saved line. On the tablet both cordn rows now read "cordn-net" — the coordinator's announced name — where they read "cordn" before.

Match cordn-web's ChatPinnedRibbon instead: one pin at a time on a single line, prev/next arrows that wrap, an "n/m" counter when there is more than one, and a list button that opens the full set in a dialog capped at 360.dp. Tapping the line jumps to the message; unpin moves into the dialog, where each entry shows who pinned it. The carousel index is clamped on read, so unpinning the last entry cannot leave it out of bounds. Ordering is unchanged -- CordnAnnotationIndex.pinnedIds() already sorts by pinnedAt then cursor, the same rule cordn-web uses. Not exercised on a device.

It is the fact that shapes everything else on the page: one server carries every message in this group, in order, and which one that is matters more than any of the group's own settings. It now comes first, directly under the title, with the avatar and name it already knew how to resolve. Its exposure card moved into a dialog on an (i) beside it. The card is a paragraph, five bullets and a footnote — worth reading once, and it was occupying a screenful on every visit, which is how a disclosure becomes scenery. Behind a button it is one tap away the once it is wanted, and the button disables itself until the exposure has actually been computed rather than offering a dialog with nothing in it. Nothing about what is disclosed changed, and it is still computed per group rather than asserted. Verified on the tablet: Coordinator / cordn-net / (i) directly under the header, and the dialog carries the whole card.

Nine titles and sentence openers now capitalise it: the settings hub, coordinators, key packages, backup, invitations, the group-type header, the new-conversation entry, and the inbox row's content description. Sentence-initial only. Mid-sentence "cordn" is left alone, because that is the project's own styling everywhere it writes its name — the spec, the site and this repo's history all use it lowercase — and the ordinary convention for a lowercase-styled name is to capitalise it where a sentence starts and nowhere else. Search keywords are left alone too: they are matched, not read. `cordn1…` is untouched, being a bech32 prefix rather than a word. Also drops `cordn_group`, which is now dead: the inbox pill it filled was replaced by the coordinator's name, and nothing else referenced it.

It takes no arguments and answers with every identity the coordinator holds a package for, which means one call covers everybody and per-person probing would be the same download repeated. So CordnKeyPackages now keeps that response as a snapshot: identities for everyone, full entries for us, reused for a minute. Cost is unchanged. topUp/ensureLastResort/listPublished already made this exact call and discarded everyone else's rows; they now go through refresh(), which warms the snapshot on the way past. The badge is fetched only once the field is in use, so opening group info downloads nothing. Publish decisions never read the reused copy. Minting against a stale listing is the one place staleness does damage -- the coordinator keeps one last-resort package per identity, so a second publish silently evicts the first and strands every invite that referenced it. publishNew/withdraw drop the snapshot. Only identities are retained for other accounts, not their kp_refs: a Welcome is addressed to a ref obtained by taking the package, never to one read out of a listing, and on a busy coordinator those refs are the bulk of an unpaginated response. The badge marks the yes and says nothing about the no, because the answer has three states: published here, not published here, and a lookup that never came back. Only membership was something we were told, so an unmarked row asserts nothing and stays fully tappable -- a "cannot be added" marker would turn an unreachable coordinator into a claim about a person. Not exercised on a device.

Each showed a name and one line of text, and that line was broken. **"Last announced Aug 7 ago".** `timeAgoNoDot` answers with a span for something recent and an absolute date for anything past a month, and one template served both. Every stale row read as nonsense. The date branch now gets a template with no "ago" in it. **Rows that could not be told apart.** The reference server ships as "My coordinator", so a dozen rows carried that name and nothing else. A pubkey prefix is appended to the names that actually collide, so the common case stays clean — "My coordinator · b9d8fac7" next to a plain "cordn-net". **Nothing about where or what.** The relays were already in `DiscoveredCoordinator` and simply never drawn; rows now show the hosts (two, then a count) and the coordinator's own `about` when it published one, which turns out to be the most telling line on the page: "Cordn coordinator running in a browser tab; key package quota 32 per identity". **55 rows deep.** Anything that has not announced in a month is folded behind "Show 55 that stopped announcing", with a line saying why it matters — creating a group on a coordinator that has gone away fails at the first call. Live ones are capped at eight with "Show all N". On group count: there is no such number to show. The eleven coordinator tools have no group listing and should not — a coordinator enumerating its groups to a stranger would leak exactly what the exposure card promises it does not. Liveness, relays and the advertised surface are the honest substitutes. **Not a LazyColumn**, which was my first instinct and is wrong here: this screen is a form, and a lazy list disposes what scrolls off, which for the text fields below would throw away focus and IME state mid-typing. Capping the rows bounds composition without putting a form inside a recycler. Also capitalises the last two stragglers, the screen title and the picker's call to action.

From 8026f43ca7f62d0157cc5daaa18d2f241f7ab237 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 25 Sep 2026 21:25:59 +0000 Subject: [PATCH 137/148] fix(cordn): name the coordinator everywhere it was a hex prefix Eight places still identified the coordinator by its key. Three already used CoordinatorIdentityRow; the rest printed `label ?: pubKey.take(16)`, so an unlabelled coordinator was a row of hex on screens where it is the party being trusted. The worst was the link inspector, which printed the full 64 characters -- on the one screen whose job is deciding whether to act on a cordn link. It, the invitation card ("via ..."), the create-group picker, and the key-package heading now carry the avatar as well as the name; accepting an invitation or picking a coordinator is a decision about who that server is. The unreachable-coordinator notice and the message details sheet get the name only: NoticeCard takes a String title, and the details sheet is deliberately technical, sitting beside a raw cursor number. Discovery offers on the coordinators screen already had an avatar and only needed the name to fall through to the profile when the announcement carries none. Nothing gains a hex fallback: coordinatorDisplayName ends at the profile's display name, which for a coordinator with no kind 0 is the short npub the rest of the app shows. CordnExposureCard keeps text only, but as an npub rather than a hex head. Its own comment said the value exists to be compared "against an npub they were sent" -- which a hex prefix cannot be, different encoding and different alphabet. Name and face are out of reach there: it is shared code with no AccountViewModel, and it is a footnote under a disclosure rather than an identity surface, with the coordinator named properly nearby on every screen that embeds it. Not exercised on a device.

Ordering the roster first makes the coordinator a calculation rather than a guess. An invitation is a Welcome left on a coordinator against a KeyPackage the invitee published *there*, so once the people are named each candidate has a hard number -- kp_list for that coordinator intersected with the roster -- and the screen can say "reaches all 5" or "reaches 3 of 5, the rest would be left out" instead of offering a radio list with no distinguishing detail. Four numbered steps: name, people, where it lives, who can add and remove. The coordinator collapses to one row carrying that number, with the whole list one tap behind Change, because with a roster in hand there is usually nothing left to decide. Coverage is asked only of coordinators this account already has a session with. Opening one is what commits to a coordinator, so a discovery offer reports "not checked -- picking it will ask" rather than being probed behind the user's back. A coordinator that did not answer reports unknown, never zero: an unreachable server must not render as a claim that somebody has no key. Admins become the choice the reference client makes. Today it is one switch only because a group starts with nobody else in it; with a roster, any member can be named, and choosing anybody still includes you or the group is born unadministrable. createGroupAndInvite returns a row per invitee instead of one exception, because createGroup and each invite are separate calls and the group can exist with part of the roster invited. Invites run sequentially -- each Add is a commit advancing the epoch, so two in flight would collide. Somebody the coordinator holds no KeyPackage for is not attempted at all and is offered a share link instead, which is the only direction that can reach them, and which needs the group to exist first. Not exercised on a device.

It is the step every later one depends on -- the coordinator's coverage is computed from it -- so it gets its own destination, Route.CordnCreateGroupMembers. That needed the form to outlive one screen. A Navigation destination is disposed when you leave it, so the name, the roster and a finished discovery run all lived in `remember` and would have been lost on the way to the roster and back. CordnGroupDraft holds them instead, scoped to the Activity and keyed per account, which is what the chess lobby and board already do to share one ViewModel. It also closes a latent hole: until now nothing navigated away from this screen, so nothing noticed the state was not survivable. The draft owns admin_pubkeys rather than the screen: adminPubKeys(creator) returns empty in egalitarian mode and the creator plus their choices otherwise, never the choices alone -- spec/01.md §5.3 makes a non-empty list permanent, so one that left out the creator would produce a group nobody present could administer. Step 2 becomes a row of faces and a count, with the number of people no coordinator can reach when there are any. rememberCordnCoverage is shared by both screens; the second copy of the question usually costs nothing because CordnKeyPackages reuses its kp_list snapshot for a minute. A created group clears its draft, on the happy path and on dismissing the outcome dialog alike: the group exists by then, and a spent roster left behind would seed the next new group with the last one's people. Not exercised on a device.

An unanswered coordinator created the group with nobody invited. `coverage` reports `reachable = emptySet()` with `answered = false`, and the create action read `reachable` directly, so "we could not ask this coordinator" became "invite nobody" -- then reported every person as having no key there. Reads through `takeIf { it.answered }` now, so unknown means attempt everyone and let each call say what went wrong. The has-a-key badge on the member search was dead code. Coverage is the roster intersected with what a coordinator holds, so somebody not yet added can never appear in it -- exactly the people the badge is for. It reads an unfiltered identity set now. A hand-entered coordinator could be overwritten. `userPicked` was set by the radio rows only, so typing a pubkey while the roster filled let the best-coverage effect replace it. Inviting one at a time was unsafe, not just slow. `MlsGroup.addMember` applies its Commit locally before anything is posted, so an invite whose postCommit failed left the group an epoch ahead of both the coordinator and disk, and every later invite in the loop built on the fork. `CordnGroupManager.inviteAll` takes and verifies every KeyPackage first, then commits once and stores one Welcome per joiner -- N failure windows collapse to one. It cannot remove the last one, since the engine has no rollback, but a failure can no longer cascade. One epoch for the whole roster is also what the reference client produces; `MlsGroup.addMembers` was written for this and went unused. `shortNpub` guarded the wrong exception. `Hex.decode` validates no characters and indexes a 256-entry table by char code, so anything above U+00FF throws ArrayIndexOutOfBounds straight through an IllegalArgumentException catch -- the opposite of the KDoc's promise. Uses the total `decode64OrNull`. The outcome dialog also lost a distinction the batch result introduced: somebody whose Welcome failed after the commit IS a member and needs a resend, where a refused invitee never reached the group and needs a link. Kept apart. Three tests on inviteAll, including the epoch count. Mutation-checked: putting the per-member loop back makes the epoch test fail. Not exercised on a device.

The coordinator came back with its groups, and the only way to be rid of it was Purge, which destroys MLS state and is not the same decision at all. `remember()` writes the coordinator list by merging the open sessions over what is already on disk, and that merge is deliberate: `registry.coordinators` holds only the sessions that OPENED, so a coordinator whose relay was unreachable this launch is missing from it, and saving that set verbatim would erase it — turning "your relay was down" into "your groups are gone", silently and permanently. A forgotten coordinator is missing from the open set for the other reason and looks identical from inside the merge. So the protection meant for the unreachable one covered the removed one too, and `forget()` — which calls `remember()` right after dropping the session — wrote the entry it had just removed straight back to disk. The merge cannot infer the difference, so `forget()` now tells it: `remember` takes the key being dropped and excludes it from the kept set as well as from the open one. Nothing else changes, and a coordinator that merely failed to open is still protected. Verified on the tablet: Remove, force-stop, cold start — the coordinator is gone and the other one is still there. The test fails without the fix.

Adds NavBarItem.CORDN_GROUPS, which puts it in the drawer beside the Marmot rooms and makes it pinnable as a bottom-bar tab like every other entry. Route.CordnGroupList opens a list of the groups this account is in. It exists alongside the inbox rather than duplicating it: the inbox mixes every type, which is right for reading and wrong for finding, and for a cordn group the question when something stops arriving is always "which coordinator" rather than "which relay". It renders from local state alone -- CordnGroupList.all, which CordnRuntime already holds -- so BottomBarFeedPreloaders has nothing to warm for it, for a different reason than Marmot's: a cordn message never arrives over a relay REQ at all, it arrives as a coordinator call the sync loop already makes. Ordered off the same `revision` signal the inbox ordering uses, because a room's newest message changes inside the room object and ordering on `all` alone would freeze after the first message. Reuses the inbox's own CordnGroupRoomCompose (now internal) rather than a second rendering of the same row: it already reads the live name, preview, annotations and unread count off the room, and two of those drifting apart would be a bug nobody would look for in a list screen. Icon is Dns, matching every other cordn surface -- a coordinator is a server, and that is what distinguishes these rows from the Marmot ones above them. Not exercised on a device.

From bb5084647e6dc2a8b92cdb3d9e7e94a389785dfe Mon Sep 17 00:00:00 2001 From: Vitor Pamplona Date: Sat, 26 Sep 2026 10:50:31 -0400 Subject: [PATCH 143/148] fix(cordn): unsquash the coordinator avatar, and keep the picker across a profile Two faults on the same row of New Cordn group. **The avatar drew as an oval.** It was given `pictureModifier = Modifier.padding(end = 8.dp)` for spacing, and that parameter is the INNER modifier: it styles the image inside a box already fixed at `size`, which is why the sibling discovery screen uses it for a border. An end padding there took 8.dp off the drawable's width and nothing off its height, so every coordinator rendered 16x24. The spacing moves out to a Spacer and the picture gets its box back. No other caller misuses it. **Returning from a coordinator's profile lost the picker.** The avatar is tappable, and it is the one place this form navigates away from. The draft is a viewmodel scoped to the activity, so the typed name and the chosen coordinator already survived; the picker's own state did not, because it sat in the screen's `remember`. Coming back, the section had collapsed to "No coordinator chosen" and the discovery results were gone -- and that discovery is a ~30-second round trip to every relay, the most expensive thing on the page to be made to repeat. `coordinatorOpen`, `discovered`, `showStale` and `showAllLive` move into the draft, which already outlives the screen, and `clear()` resets them with the rest so the next new group does not open on the last one's search. The purely transient state -- `busy`, `error`, `creation`, `discovering` -- stays local on purpose: a spinner that survived a trip away would be lying. Verified on the tablet: the avatar is round, and after tapping through to the coordinator's profile and back the name, the open picker and the discovered rows are all still there.

Its own KDoc argued it existed because "for a cordn group the question is always which coordinator" -- and then showed no coordinators. Sections by coordinator now, each headed by its avatar, name, group count and CoordinatorHealthRow, which already existed and went unused here. A coordinator that has stopped answering is named in error colour, carries one line saying nothing is arriving, and dims the groups under it: those groups are not each broken, the one server they share is, and that is a fact the inbox structurally cannot show. Dimmed rows stay tappable, because the history already on the device reads fine without the coordinator. It still costs no network. CordnRuntime.health is a local StateFlow of what the calls the sync loop was making anyway observed -- it never polls, because a poll is a call and every call is metadata (§8). Key-package health is deliberately left out despite an empty pool meaning nobody can invite you: the only truthful source is the unpaginated kp_list, and fetching it per coordinator to decorate a list is the cost this branch has been careful to avoid. It stays one tap away behind the new Coordinators action in the top bar. Fixes three inconsistencies in the version this replaces: the divider used the default thickness where every other row list uses DividerThickness, drew one after the last row, and the no-groups case was a hand-rolled centred Column while the runtime-null case beside it used the shared EmptyState. Also fixes a Compose hazard I had introduced: health was collected behind a `?.`, making collectAsStateWithLifecycle a conditional @Composable call on a branch that flips when a session opens mid-screen. The null is resolved into a flow before collecting, keyed on the coordinator list so it re-resolves when a session does appear. Not exercised on a device.

A Card inside a Card. SettingsSection already IS the card -- rounded at 20.dp, surfaceContainer -- and CoordinatorCard drew a second one inside it at a different grey, which stacked full-width with its neighbours into a square-cornered slab sitting in the section's rounded one. Every other cordn settings section puts its content straight into the form block; this one is now a plain Column with a divider between coordinators and none after the last. The raw 64-character hex. It sat under the name with a comment arguing the key must stay in full because this is the screen where you verify the coordinator you were told to use. The argument is right and the rendering defeated it: what somebody is told is an npub, and a hex string cannot be compared against one at all. Short npub now, with the full npub one tap away on the clipboard, which is how a comparison is actually made. Reuses CopyableKeyRow from the group-info Technical details rather than a second one. No hierarchy. Name, key, relays, health and server info were five bodySmall lines at 4.dp spacing, so the one question the screen is opened with -- is this coordinator working -- read the same as everything else. Health moves up beside the name; the key and the relay list become labelled blocks, every relay shown because ruling one out is why you came. And Purge sat inline beside Identify, same size: one tap from a harmless handshake to deleting a coordinator's groups and keys off the device. Remove and Purge are behind an overflow menu now, Identify stays a button. Caught while wiring it: cordn_coordinators_relays already exists as a "%1$s" format string for the relay summary elsewhere, so reusing that name for a section label would have rendered the placeholder. The label has its own key. Not exercised on a device.

The voice path was unaffected because it posts its recording already encoded and never compresses, which is why sending audio worked throughout while sending a picture never did. This is the same symptom I looked at earlier in the week and wrongly wrote off as the picker returning a null uri. It was not; the picker was fine. Reproduced on the tablet with the stack trace, fixed, and a checkerboard PNG now encrypts, uploads and renders inline in the group -- visibly recompressed, so the step that used to throw is the one doing the work. `resolveDisplayName` goes off-main with it. It queries `OpenableColumns`, which is a disk read, and StrictMode was flagging it on the same send. **The backup passphrase was not treated as a secret by the keyboard.** The field set `PasswordVisualTransformation` but no `KeyboardType.Password`, so the dots were the only protection: Samsung's IME offered the passphrase in the suggestion strip in the clear and learns it into the personalised dictionary, where it outlives the app. This file was the only one of the five password fields in Amethyst missing it.

A file chosen through that handoff came back as a cancelled result, so `pendingRestore` stayed null, the confirmation dialog never appeared, and Restore looked like a dead button. It reproduced from both the Recent list and the Downloads view. A cordn archive is not media. ACTION_OPEN_DOCUMENT is the right intent for it and reaches SAF directly, so `OpenDocument` replaces `GetContent`. The other `GetContent` in the app picks an image for a calendar event, where going to the photo picker is correct; it is left alone. Verified on the tablet: the picker now opens straight into DocumentsUI, picking the archive raises the "Replace this device's cordn groups?" dialog, and the restore completes and rebuilds both groups.

The archive carried the MLS state, the cursor and the key packages but not one message, and the cursor it *did* carry told the sync loop the stream had been read to the end — so the coordinator was never asked to resend them either. Verified on the tablet with a true no-op round trip (export, restore that same file minutes later): both groups came back with names, icons, members and health, and every message gone, still gone after a cold start, and gone from the Messages inbox entirely for want of anything to sort on. That is not what the screen offers. Its first line is that losing the device without a backup loses "everything already said in it", which only reads one way. Archive version 2 adds the delivered messages per group, written as the same JSON the on-disk message log already stores so the two cannot drift. Version 1 files still open, and still restore empty — there is nothing in them to do better with. The import writes the messages back before the cursor is trusted again, because nothing will re-deliver them afterwards. The alternative was to reset the cursor on restore and re-pull from the coordinator, which does hold the complete ordered history. It is cheaper, but it only recovers the epochs the restored state can still open; carrying the plaintext is whole regardless of how often the group has rotated. Vitor picked this one. The "What is in the file" copy now says messages are in there, since that materially changes what the file is worth to whoever finds it.
