From 741c377f805b90730bd7accf85758054d7390293 Mon Sep 17 00:00:00 2001 From: nrobi144 Date: Thu, 2 Jul 2026 18:03:12 +0300 Subject: [PATCH 001/176] fix(desktop-cache): scope consumeContactList to active user + fan out to SharedFlow The old implementation tracked kind-3 replaceability with a single global `lastContactListCreatedAt` scalar and unconditionally overwrote `_followedUsers` on every accepted event. Once *any* subsystem starts fetching other users' kind-3 events (WoT scoring, mutual-follow lookups, etc.), a newer-createdAt kind-3 from a follower silently hijacks the active user's follow-set state, cascading into feed filters, mute logic, and sidebar counts. Fix by tracking newest-per-author (`ConcurrentHashMap`) and guarding writes to `_followedUsers` / `lastContactListEvent` on `event.pubKey == accountPubkey`. `accountPubkey` is bound from `Main.kt` on login. Also expose `contactListEvents: SharedFlow` (buffer 64, DROP_OLDEST) so downstream consumers (the incoming WoT service) can observe every accepted kind-3 without adding a bespoke listener API. --- .../desktop/cache/DesktopLocalCache.kt | 51 ++++++++++++++++--- 1 file changed, 43 insertions(+), 8 deletions(-) diff --git a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/cache/DesktopLocalCache.kt b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/cache/DesktopLocalCache.kt index d32ba9093f..c8a7bd3b7d 100644 --- a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/cache/DesktopLocalCache.kt +++ b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/cache/DesktopLocalCache.kt @@ -66,6 +66,7 @@ import kotlinx.coroutines.flow.MutableSharedFlow import kotlinx.coroutines.flow.MutableStateFlow import kotlinx.coroutines.flow.SharedFlow import kotlinx.coroutines.flow.StateFlow +import kotlinx.coroutines.flow.asSharedFlow import kotlinx.coroutines.flow.asStateFlow import kotlinx.coroutines.launch import java.util.concurrent.ConcurrentHashMap @@ -91,6 +92,27 @@ class DesktopLocalCache : ICacheProvider { private val _followedUsers = MutableStateFlow>(emptySet()) val followedUsers: StateFlow> = _followedUsers.asStateFlow() + /** + * Active user's pubkey (hex).

For pubkey X the score is the count of accounts in the active user's follow set who also follow X — Gossip / Snort convention. v1 is display-only; no threshold filtering. Data flow - `commons/wot/WoTService` — sparse `SnapshotStateMap` + reverse index + per-follower snapshot for diff-based updates. Single-writer coroutine (Channel → `Snapshot.withMutableSnapshot`) serializes all mutations. Cap at 5000 follows/event blocks DoS via hostile kind-3s. Guardrail at 2000 follows/account skips WoT for mega-accounts. - `DesktopIAccount.wotService` — per-account instance, matches `Kind3FollowListState` / `BookmarkListState` conventions. - `Main.kt` binds `localCache.accountPubkey`, collects `localCache.contactListEvents` → `applyKind3`, collects `localCache.followedUsers` → `onFollowSetChange` + `subscriptionsCoordinator.loadKind3Batched(...)` with `onEose = markReadyOnce`. 2 s fallback timeout guarantees badge visibility even if index relays never EOSE. - `FeedMetadataCoordinator.loadKind3Batched(pubkeys, onEose)` — chunks authors into ≤100 per Filter within one subscription. Matches nostr-rs-relay defaults. UI - `commons/ui/components/UserAvatar` gets an optional `badge: @Composable BoxScope.() -> Unit`. Android call sites pass null (no compile-time coupling to Desktop-only tooltip APIs). - `desktopApp/.../ui/note/WoTBadge` — Material3 `TooltipBox` + `PlainTooltip` (multiplatform-ready, keyboard/screen-reader a11y). `rememberTooltipState(isPersistent = true)` fixes the vanish-too-fast desktop default. - `desktopApp/.../ui/note/WoTBadgedAvatar` — drop-in replacement for `UserAvatar` that overlays the badge when `LocalWoTService != null && LocalWoTReady && pubkey !in LocalSpamExemptKeys`. Score read is a plain `service.scores[userHex] ?: 0` — snapshot system tracks per-key, so avatars only recompose when their own score changes. - Call-site migration at 4 v1 surfaces: NoteCard header (covers feed / thread / bookmarks / search / QuotedNoteEmbed via NoteCard), FeedNoteCard repost header (2 avatars), UserProfileScreen header (2 sizes). Amy verbs - `amy wot get [--json]` — hydrates a WoTService from the local FsEventStore, prints score for target pubkey. - `amy wot list [--threshold N] [--limit K] [--json]` — sorted score list. - `amy wot sync [--timeout N]` — batch-fetches kind-3 for the active follow set from outbox/inbox relays, persists to the event store. Tests + docs - 14 unit tests: `WoTServiceTest` covers happy path, sparse map, self/follower exclusion, kind-3 churn diff, guardrail, event cap, ready gate, clear. - Manual testing sheet with 17 scenarios at `desktopApp/plans/2026-07-01-wot-score-manual-testing-sheet.md`. - Plan at `docs/plans/2026-07-01-feat-desktop-wot-score-plan.md`.

Explicit call-site migration is a feature: it lets us + ship v1 on high-value surfaces (feeds, thread, notifications, profile) + and defer minor spots. +- **Slot on `UserAvatar` for Desktop-owned rendering.** Even the + sibling composable needs somewhere to draw the badge. Adding a + scalar `badge` slot to `UserAvatar` avoids duplicating the entire + avatar layout and keeps Android intact (nulls the slot). +- **Sparse `SnapshotStateMap`.** Storing `Unknown` for every unqueried + pubkey would bloat the map to 250 k entries; keeping it sparse (only + positive scores) reduces subscriber overhead 10×. +- **Chunked batch REQ.** Relays vary wildly in filter-size caps + (nostr-rs-relay defaults ~100, strfry accepts hundreds). Chunking + 100 authors per Filter within one subscription is the correct + pragmatic default. +- **Diff-based `applyKind3`.** Kind-3 events churn (many clients + republish frequently). Full recompute on every event would drop the + reverse index and lose recomposition isolation.

Tests were constructing a fresh DesktopLocalCache() (accountPubkey = null) and publishing kind-3s authored by `userPubKey` / `ownerPubKey`, so the guard silently rejected them and `followedUsers` stayed empty.

Before this change: - Desktop hard-coded `DefaultRelays.RELAYS` at coordinator construction; users could not override. - `amy wot sync` used `outboxRelays().ifEmpty { inboxRelays() }` — NIP-65 write / DM inbox relays, which are semantically different from index relays. `amy wot get` after `amy wot sync` could return a different score than the Desktop UI would compute. New `PreferencesIndexRelays` (commons/jvmMain) is a tiny class backed by `java.util.prefs.Preferences.userRoot().node("com/vitorpamplona/amethyst/relays/index")` — the same JVM-user-scoped shared-node trick `PreferencesHashtagSpamSettings` already relies on. Both Desktop and amy running as the same OS user observe the same value with zero extra plumbing. App-global (not per-account); users typically have one preferred index-relay set regardless of which account is logged in. Behaviour changes for users who never open the settings UI: none. `DEFAULT_INDEX_RELAYS` is byte-for-byte identical to the four URLs in `DefaultRelays.RELAYS`. Wiring: - `DesktopRelayCategories` gains a straight-through `indexRelays` StateFlow (no combine — index relays are a curated user choice, not a NIP-65-derived set) plus `setIndexRelays(new)`. - `Main.kt` instantiates `PreferencesIndexRelays` at App() root and passes it into both the subscriptions-coordinator constructor and `DesktopRelayCategories`. Coordinator snapshots the effective set at construction — changes take effect on next relaunch (documented in the settings section explainer). - `Context.indexRelays()` reads the same preferences node so `WotCommand.sync` produces identical relay batches to Desktop. - New `IndexRelaysSection` composable in `desktopApp/.../ui/settings/` — list + per-row remove + add-row with URL normalisation. Deletion of all entries falls back to defaults (delete-all is the reset — no separate "Reset" button). Placed between the Local Relay and Content Filters sections of the Relays settings screen. Tests: - `PreferencesIndexRelaysTest` — defaults fallback, round-trip persistence, blank-token skipping, non-empty defaults guardrail. - Full existing test suites remain green. Companion PR (search-result badges) landed on `feat/wot-search-badges` and is this branch's parent. Both remain stacked on the WoT feature branch pending upstream review.

Ship it alone. Items 2 + 3 stay bundled + because the UI (Item 3) is the write path for the persistence + (Item 2) — reviewing them separately means reviewing dead code or a + headless feature. +2. **App-global (not per-account) index-relay override.** First draft + made this per-account to match `searchRelays` / `dmRelays`. But + `searchRelays` / `dmRelays` are per-account because they're NIP-51 / + NIP-17 identity-scoped semantics; index relays are a user preference + about where profile-metadata lookups go, and users have a single + preferred set regardless of which account they're logged into. + App-global halves the API surface and matches user mental model. +3. **`PreferencesIndexRelays` in `commons/jvmMain/`, not extending + `DesktopAccountRelays`.** Verification found `DesktopAccountRelays` + uses `Preferences.userNodeForPackage(DesktopAccountRelays::class.java)`, + which is a per-class node — **not visible to amy** running from a + different classpath. To achieve the "one truth for Desktop and amy" + goal, the shared node must be an explicit + `Preferences.userRoot().node("com/vitorpamplona/amethyst/relays/index")`, + which is exactly the pattern `PreferencesHashtagSpamSettings` uses. + New small class mirrors that shape. +4. **Drop `WoTBadgedSearchCard`.** Only two call sites; the 6-line + score computation inlines cleanly. New wrapper composable earns its + keep at 3+ call sites, not 2. +5. **Drop `DefaultIndexRelays.kt` in commons.** Speculative — no + Android caller. amy can duplicate the 4 URLs (they change ~never) + or read a single constant from a shared location. Extracting to + commons is architectural neatness without a consumer. +6. **`DesktopRelayCategories.indexRelays` uses `override ?: default` + only.** Not the full combine used by `searchRelays` (which + intersects with NIP-65 discovery). Index relays are a curated user + choice, not a "what's actually reachable right now" derived set. No + `debounce` / `stateIn` combine needed — a straight-through StateFlow + from the Preferences read is enough. +7. **Drop "Reset to defaults" button in Item 3.** Removing all relays + from the UI already falls back to `DefaultRelays.RELAYS`. Delete-all + IS the reset. +8. **Drop integration scenarios 2 and 6.** #2 (badge respects + exemptions) is covered by existing `WoTBadgedAvatar` tests — same + code path. #6 (empty override falls back) is a single unit test on + `PreferencesIndexRelays`, not a manual scenario. +9. **`RelaySettingsScreen` current content** was mischaracterised — it + already has 6 sections (Wallet Connect, Media Server, Image + Compression, Tor, Namecoin, Local Relay, Content Filters). Index + Relays fits between Local Relay and Content Filters (both have + dividers). +10. **Adopt-not-in-this-PR discovery: `commons/AmethystDefaults.kt` + already has `DefaultIndexerRelayList`** (Purple Pages, Coracle, + etc). Desktop today uses the wrong list (`DefaultRelays.RELAYS` = + general-purpose relays) for its index REQs. That's a real + behavioural bug worth a separate ticket — not this one — because + changing default index relays is a user-visible behaviour shift and + deserves its own review. + +--- + +## Overview + +Three small follow-ups to the just-shipped Web-of-Trust score feature +(branch `feat/desktop-wot-score`, closed for manual testing): + +1. **Badges on search-result person cards.** The main NoteCard header + already renders `WoTBadgedAvatar`, but the Search screen's person + picker uses a different composable (`UserSearchCard`) that doesn't + currently accept a badge. +2. **Unify amy `wot sync` with Desktop on the same relay set.** Desktop + currently uses a hard-coded `DefaultRelays.RELAYS` list as its + `indexRelays`; amy uses whatever the user's NIP-65 outbox/inbox lists + contain. When the two disagree, `amy wot get` after `amy wot sync` + returns a different score than the Desktop UI would compute. +3. **Add an Index Relays section to the Relays settings screen** so + users can customise which relays back both surfaces from one place. + +**Shipping plan:** two PRs. + +- **PR A — Search badges (Item 1).** ~40 LOC, one commons param + addition, two Desktop call-site inline changes. Independent of the + other work. Ships first. +- **PR B — Shared index relays (Items 2 + 3).** Introduces a small + Preferences-backed class in `commons/jvmMain/`, wires the coordinator + to read from it, adds a settings-screen section, and updates + `amy wot sync` to read the same node. ~300 LOC. Ships second. + +## Problem Statement + +Three concrete regressions/gaps from the manual-testing pass of the WoT +PR: + +- **Item 1.** When searching for a person in the Desktop search screen, + their result card is a stranger 90% of the time (that's the point of + searching), but there's no trust cue on the card. Users who find WoT + badges useful on feed avatars want the same signal here. +- **Item 2.** amy's `wot sync` uses `ctx.outboxRelays()` (NIP-65 write + list) with a fall-back to inbox. Those are legitimate relays for + publishing / receiving events, but they are *not* what Desktop uses + to fetch profile metadata and follow lists — Desktop hits a + hard-coded `indexRelays` set (nos.lol, nostr.wine, + relay.noswhere.com, relay.primal.net today). Result: `amy wot get` + after a fresh `amy wot sync` can produce a score that lags or + diverges from the Desktop UI for the same account. +- **Item 3.** The Relays settings screen already contains six + sections; there's no UI to inspect or change which relays are + considered "index relays" — the values live only in the hard-coded + default list in `RelayStatus.kt`. + +## Proposed Solution + +### PR A — Item 1: Badge slot on `UserSearchCard` + +`UserSearchCard` in +`commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/ui/components/UserSearchCard.kt` +gets an optional `badge` slot that forwards to its embedded +`UserAvatar` (which already has the slot from the WoT PR): + +```kotlin +@Composable +fun UserSearchCard( + user: User, + onClick: () -> Unit, + modifier: Modifier = Modifier, + badge: @Composable (BoxScope.() -> Unit)? = null, +) { + // Existing layout, unchanged, except: + UserAvatar( + userHex = user.pubkeyHex, + pictureUrl = user.profilePicture(), + size = 40.dp, + contentDescription = stringResource(Res.string.accessibility_user_avatar), + badge = badge, + ) + // …rest of the Row unchanged +} +``` + +Backward compatible — default `null` means no visual change for callers +that don't opt in. The layout impact is zero: `UserAvatar` handles the +badge's `Box` overlay itself; the badge lives on the avatar's bottom- +right corner, and the `ArrowForward` icon at the row's trailing edge +doesn't collide with it. + +Two Desktop call sites in +`desktopApp/.../ui/search/SearchResultsList.kt:116,126` inline the score +computation directly at the call: + +```kotlin +val service = LocalWoTService.current +val ready = LocalWoTReady.current +val exempt = LocalSpamExemptKeys.current +val score = if (service != null && ready && user.pubkeyHex !in exempt) { + service.scores[user.pubkeyHex] ?: 0 +} else 0 + +UserSearchCard( + user = user, + onClick = { … }, + badge = if (score > 0) { + { WoTBadge(count = score, modifier = Modifier.align(Alignment.BottomEnd)) } + } else null, +) +``` + +The two sites are 4 lines apart; a small local `remember` block above +them can factor the read if we want (optional micro-cleanup — not +required). + +**Not migrated in PR A:** + +- `desktopApp/.../ui/chats/NewDmDialog.kt` (three sites) — the DM + recipient picker. Same rationale as before: when picking a DM + recipient you're already committing to messaging that person; a + trust badge is more noise than signal. Add later if testing calls + for it. + +### PR B — Item 2: Shared `indexRelays` between Desktop and amy + +#### Persist via `java.util.prefs`, node shared with amy + +`Preferences.userRoot().node("com/vitorpamplona/amethyst/relays/index")`. +Same JVM-user-wide `java.util.prefs` trick the hashtag-spam PR (#3431) +uses — Desktop and amy running as the same OS user see the same node. + +**Not stored per-account.** Users have a single preferred set of index +relays regardless of which account is logged in. Halves the API +surface and matches user intuition. If a user with two accounts +genuinely needs separate index relays per account, we add per-account +overlay later on demand — YAGNI now. + +**Not persisted via `DesktopAccountRelays`.** That class uses +`Preferences.userNodeForPackage(DesktopAccountRelays::class.java)`, +which resolves to a per-class node that `cli/` running from a different +classpath **would not see**.

UI reads from +`LocalRelayCategories.current.indexRelays`. + +**Changes take effect on next relaunch.** Documented in the settings +section's help text.

Only the row for +the changed pubkey recomposes when its score updates. Identical +behaviour to what we shipped in `WoTBadgedAvatar`; the wrapper +composable would have added a subscriber node with no gain. + +### Live re-targeting of the coordinator (Item 2) + +Existing `DesktopRelaySubscriptionsCoordinator` reads `indexRelays` +once at construction and holds it. Teaching it to swap +`indexRelays` mid-flight is a real refactor (in-flight subscription +state, cross-EOSE semantics). Ship "changes take effect on next +relaunch" for v1; add live re-targeting in a follow-up if users notice. + +### Preferences node identity across Desktop and amy (Item 2) + +Both processes use +`Preferences.userRoot().node("com/vitorpamplona/amethyst/relays/index")`. +Because `java.util.prefs.Preferences` is JVM-user-scoped +(per OS user, per prefs backend — plist on macOS, dconf on Linux, +registry on Windows), both processes end up looking at the same +physical store. `PreferencesHashtagSpamSettings` already relies on this +guarantee in shipped code. + +### CSV vs JSON serialisation (Item 2) + +CSV (`joinToString(",") { it.url }`) matches what `DesktopAccountRelays` +does for its categories.

From 6ff2e542120c6e2b71d8d125ac3e94f8c65f17e8 Mon Sep 17 00:00:00 2001 From: nrobi144 Date: Mon, 6 Jul 2026 09:53:28 +0300 Subject: [PATCH 006/176] refactor(desktop): move Index Relays UI to Relays dashboard, match sibling-editor UX MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Relocates the shared index-relays editor off the Configure/Settings screen and into the Relays column's Configure tab as a 6th collapsible section next to Connected / NIP-65 / DM / Search / Blocked relays — where users already look for relay-list editing. Rewrites the section to match the SearchRelayEditor pattern: local SnapshotStateList buffer seeded from the persisted set, OutlinedTextField with a compact IconButton(Add), per-row Close remove, Enter-key add, plus a Save button that commits the buffer to PreferencesIndexRelays and a Reset-to-defaults button that reseeds the buffer with the 4 built-in defaults. Adds a savedMessage toast noting the 'restart to apply' caveat.

GrapeRank is defined over follows, mutes and reports together; scoring with a signal disabled isn't a meaningful WoT.

Add the discovery layer as two sub-verbs: - `amy graperank register [PROVIDER]` — append a ServiceProviderTag (default `30382:rank`, self, first outbox relay) to the account's kind:10040, fetching the freshest list first so existing providers are preserved. Idempotent, supports `--service KIND:TAG`, `--relay`, and `--private`. - `amy graperank providers [USER]` — list a user's declared providers (cache-first; own private entries are decrypted and included). Bare `amy graperank [OBSERVER]` still computes scores; the dispatcher only peels off the `register` / `providers` words. All built on quartz's existing `TrustProviderListEvent` / `ServiceProviderTag` / `ProviderTypes`. Verified against a local geode relay: register creates the 10040 and is idempotent on re-run; providers lists both a public 30382:rank entry and a private 30382:followers entry.

Finding: our commons/wot formula and every scoring parameter are already identical to Brainstorm's DEFAULT preset (attenuation 0.85, rigor 0.5, follow 1.0/0.03, from-observer 0.5, mute/report -0.1/0.5, delta 0.0001). Our `score` is exactly their ScoreCard `influence`. Remaining divergence is data completeness, not math — and because a signal's weight scales by the rater's influence, only in-graph raters move a score, which our outbox crawl already captures. Documents the pipeline, side-by-side params, divergence sources, and follow-ups (presets, influence/verified fields).

They serve kind:0/3/10002 for the whole network and are where a stranger's relay list and contact list are actually found — the biggest completeness lever. - Per-follow relay hints are harvested from the `p`-tag hints in every contact list we crawl and used as a discovery tier below each user's kind:10002. - A per-hop retry pass re-queries any frontier member whose contact list still didn't arrive (no kind:10002, or its outbox was unreachable) against the indexer + hint set, recovering users the outbox model alone would miss. This tightens the only real source of score divergence from Brainstorm — data completeness — since a signal's weight scales by the rater's influence, so the users that matter are exactly the in-graph ones this crawl now reaches more reliably.

Also add progress status (all on stderr, stdout stays the JSON contract): - loading already logs per-hop frontier/recovered/new/total counts; - "graph built: N users, E edges; scoring…" and "scored N users" bracket the calculation; - GrapeRank.compute gains an optional (visited, scored, queued) progress callback, wired to emit a scoring line every 5000 worklist visits so a large graph shows movement instead of hanging silently.

A user is "done" once we download its contact list, or after --max-attempts (default 3) failed tries of its outbox — so an unreachable outbox can't stall the crawl, and it still terminates on a finite graph. - --max-rounds replaces --max-depth as an (unbounded by default) safety backstop. - Track and report the pool of relays actually contacted (relays_contacted), the "running relays" we connect to as more outboxes are discovered. JSON: `depth_reached` -> `crawl_rounds`, add `relays_contacted`. Per-round and final crawl-summary progress on stderr.

Round-by-round evidence — 250 users queried downloaded 205 contact lists (82%), but 17,055 queried downloaded only 137 (0.8%). Net: 93k outboxes found but only ~14k contact lists pulled, so most users had no outgoing edges and scores came out far below Brainstorm's. Fix: fetch content in bounded batches (USER_BATCH=256) drained a few at a time (DRAIN_CONCURRENCY=8). Routing (store reads) runs serially; only the drains run concurrently — inserts serialize on the store write lock, so that is safe. kind:10002 discovery stays a bulk indexer query (they aggregate 10002 and handle bulk author filters fine); only the per-user outbox fan-out is batched. Effect on the same graph: round 3 went from 137 → 4,157 contact lists downloaded (+36k events), and users scored after 3 rounds jumped 34,976 → 109,760. Full-run parity verification against the live Brainstorm set is in progress.

Each round now splits pending users into "already in the store" (expanded from disk with zero network) vs "need to fetch" (routed to their outbox). Verified on a warm store: round 2 pending=250 -> cached=236, downloaded=7; round 3 pending=19491 -> cached=15827, downloaded=87. - Build the trust graph from the store (kind:3/10000/1984 query) instead of the in-run `collected` list, so cached-and-skipped lists still contribute their edges. Online and offline paths now share the same graph source. No behavioural change on a cold store (nothing cached -> download everything once), and the crawl still runs to full graph depth with no user cap.

Point #2 (memory): replace the HexKey-keyed, TrustEdge-object graph with a compact representation that scales to the whole network: - commons/wot: pubkeys interned to dense Int ids; edges stored in two CSR IntArray layouts (by target for scoring, by source for the worklist), each incoming entry packing source id + relation into one int. GrapeRank.compute returns a DoubleArray by node id (no boxed map at millions of nodes). TrustGraphBuilder is now stateful/streaming (addFollows/addMutes/addReports). Tests rewritten; the full-sweep cross-check still passes. - cli: contact lists stream straight into the builder as they arrive and the Event is discarded — the crawl never holds millions of kind:3 objects. Mutes and reports (far fewer) are fed from the store. Output de-interns the top-N. Validated: a fresh online run built a 108,961-user / 1.67M-edge graph and scored 83,613 users in a 4 GB heap.

At crawl scale this explodes: a 96k-event GrapeRank crawl produced 5.6M tiny index files rounding up to 2.8GB on disk — only 457MB of which was actual event data. An 8-hop crawl would blow past available disk. Wire amy's shared store through a new StoreFactory that selects the backend from AMY_STORE (default `sqlite`, opt into the legacy tree with `fs`). Both implement IEventStore, so every command works unchanged. SQLite packs the same postings into shared B-tree pages — several times smaller on disk and the natural fit for large crawls. The two stores live side by side under `/shared/` (events.db vs events-store/) so switching never clobbers the other's data. `amy store` maintenance verbs are now backend-aware: stat reports the total + disk bytes for both (kind histogram/mtime stay fs-only); scrub is a no-op on sqlite (indexes are transactional); compact runs VACUUM on sqlite. Verified end-to-end via the built amy image on both backends: init, notes post round-trip (event persisted + read back), and every store verb.

Replace it with synchronous Gauss-Seidel sweeps over all nodes (in-place updates, so trust flows outward within a sweep), ending when no node moves more than the convergence delta. Same per-node formula, same 0.0001 threshold, same unique fixed point as NosFabrica's Brainstorm reference (which iterates the same way) — verified byte-identical by the existing GrapeRankTest suite — but each node is touched once per sweep instead of once per churning rater, cutting the work by roughly the average in-degree. Progress now reports per-sweep (node-updates + nodes-still-moving) and the CLI surfaces the sweep count.

Three changes: 1. Dead-relay pruning. Context.drain now reports relays that failed to CONNECT via a deadOut set; the crawl strikes them (MAX_DEAD_STRIKES=2) into a deadRelays set and excludes them from routeByOutbox and the sweep, so a wave stops re-paying the timeout on the same dead outboxes. 2. DRAIN_CONCURRENCY 8 -> 24, safe now that dead relays are pruned rather than piling up as stalled connections. 3. Sharded backbone sweep (Phase A each round): split the pending authors across the top-SHARD_RELAYS(10) live relays — one shard per relay, no relay gets the same list twice — drain all concurrently, rotate the still-missing onto different relays for up to SHARD_ROTATIONS(6) passes, then broadcast the remainder to all top relays only once it drops below SHARD_BROADCAST_THRESHOLD (2000). Phase B then outbox-routes only whoever the popular relays lacked. The old broadcast-everyone last-mile is removed (the sweep subsumes it). Each concurrent drain uses its own dead-set (no shared-HashSet race); harvest feeds from the drain's returned events instead of re-scanning contactsOf over the whole missing set. Adds download_ms so the crawl phase is timed.

Auth-gated relays sent AUTH, the client never answered, and their sub CLOSed 'auth-required' — so those outboxes served us nothing. Wire a RelayAuthenticator into Context that signs the AUTH challenge with the account key (local signer only; a remote bunker is skipped to avoid a per-relay round-trip storm mid-crawl). Signing with any key still unlocks relays that just want some auth. - No visibility into REQ failures. Add RelayDiagnostics, a connection listener that tallies NOTICE frames, CLOSED reasons by NIP-01 prefix (auth-required / rate-limited / restricted / …), and AUTH challenges. Surfaced in the crawl's stderr summary and as relay_feedback in the JSON, so a failed fetch can be explained instead of guessed at.

During login, hydration launched on Dispatchers.IO before Main.kt's LaunchedEffect bound accountPubkey. If the user's own cached kind-3 hydrated first, the map got poisoned; the same event later arriving from a relay was rejected by the createdAt gate, _followedUsers stayed empty, and FollowAction.follow would call createFromScratch and wipe the real follow list. Two-part fix: 1. Reorder Main.kt so localCache.accountPubkey is set before hydration launches. Also clear the pubkey on logout and on account switch. 2. Belt-and-braces: consumeContactList now only stamps lastContactListByAuthor inside branches where we know self identity. When accountPubkey is null (login/hydration window), skip the stamp so the relay retry that arrives after bind can populate _followedUsers. Regression tests reproduce the "hydrate before bind, replay after bind" scenario and confirm the follow set populates on retry.

Reorder `Main.kt` so `localCache.accountPubkey = +account.pubKeyHex` runs before `localRelayStore.hydrate(localCache)`. Belt + +braces: inside `consumeContactList`, do not stamp `lastContactListByAuthor` +for events where `event.pubKey == accountPubkey` unless the self path +actually accepted the event. This eliminates the "poisoned stamp" for the +future relay retry even if a caller ever forgets to bind pubkey first. + +**Fix 2 — MAX_FOLLOWS guard bypass.** Two-part fix: +- In `WoTService.handleFollowSet`, when the follow set exceeds `MAX_FOLLOWS`, + set `myFollows = emptySet()` *and* flip a `disabled: Boolean` flag.

Guardrail bypass. handleFollowSet assigned myFollows before the MAX_FOLLOWS check, so subsequent applyKind3 calls whose follower landed in the huge set fully repopulated reverseIndex/_scores — defeating the "skip WoT for mega-follow accounts" promise. Fix: check size FIRST, clear myFollows, expose a disabled StateFlow, and early-return handleKind3 while disabled. Guardrail also releases itself when the follow set later shrinks back under the cap. 3. No teardown API. WoTService owned a writer coroutine + ops Channel but had no close(). On account switch a new instance was created while the old one leaked its writer. Fix: implement AutoCloseable; close() shuts the channel so writerLoop exits and post-close trySend calls are dropped silently. Main.kt wires it via DisposableEffect(iAccount) so account switch is a clean teardown. 4. Misleading docs. KDoc claimed Snapshot.withMutableSnapshot conferred per-key isolation. That's a SnapshotStateMap property, not a withMutableSnapshot property; the wrap only coalesces an op's writes into a single Compose commit. Rewritten to be accurate so future integrators don't trust the wrong invariant. Tests: existing guardrail test extended with isDisabled assertion, plus new tests for guardrail-holds-under-applyKind3, guardrail-releases-when- follow-set-shrinks, close-stops-accepting-ops, and close-is-idempotent.

On flaky-network cold-starts where every index relay timed out, the pubkeys stayed permanently marked and WoT was silently empty for the whole session — the next call short-circuited. Fix: pubkeys enter `queuedKind3Pubkeys` / `queuedPubkeys` only after ≥1 EOSE; on zero-EOSE timeout they roll out of the new `inFlightBatched*` sets so a subsequent call retries. 6. `val eoseReceived = mutableSetOf()` was mutated from per-relay `onEose` callbacks the client dispatches on `Dispatchers.IO`. Concurrent `add()`/`size` on an unsynchronised HashSet could drop entries or throw CME, forcing the batch to wait the full timeout instead of firing early. Fix: `BatchEoseGate` funnels EOSE notifications through a `Channel` so a single consumer coroutine is the sole reader/writer of the `seen` set — KMP-safe, no `synchronized {}` or JVM-only atomics. Tests exercise: - zero-EOSE timeout → retry re-fires - ≥1 EOSE → next call short-circuits - full-EOSE from 20 relays hammered from Dispatchers.IO in parallel - clear() releases in-flight dedup - same semantics on loadMetadataBatched Plan: commons/plans/2026-07-06-fix-wot-outbox-model-and-review-fixes-plan.md --- .../assemblers/FeedMetadataCoordinator.kt | 116 +++++-- .../assemblers/FeedMetadataCoordinatorTest.kt | 297 ++++++++++++++++++ 2 files changed, 395 insertions(+), 18 deletions(-) create mode 100644 commons/src/jvmTest/kotlin/com/vitorpamplona/amethyst/commons/relayClient/assemblers/FeedMetadataCoordinatorTest.kt diff --git a/commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/relayClient/assemblers/FeedMetadataCoordinator.kt b/commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/relayClient/assemblers/FeedMetadataCoordinator.kt index ca5f1bb770..d2ba16fca3 100644 --- a/commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/relayClient/assemblers/FeedMetadataCoordinator.kt +++ b/commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/relayClient/assemblers/FeedMetadataCoordinator.kt @@ -39,6 +39,7 @@ import com.vitorpamplona.quartz.nip18Reposts.RepostEvent import com.vitorpamplona.quartz.nip25Reactions.ReactionEvent import kotlinx.coroutines.CompletableDeferred import kotlinx.coroutines.CoroutineScope +import kotlinx.coroutines.channels.Channel import kotlinx.coroutines.launch import kotlinx.coroutines.withTimeoutOrNull @@ -76,6 +77,14 @@ class FeedMetadataCoordinator( private val queuedBoostedIds = mutableSetOf() private val queuedKind3Pubkeys = mutableSetOf() + // Batched paths only — pubkeys currently in-flight in a batched REQ. + // Prevents rapid re-fire of the same batch.

Each scope keeps its own StateFlow + idle-timer Job; both scopes share the same `PrivacyLockSettings` so failed-attempt counters and lockout schedule stay device-global (brute-force protection). - `LocalMessagesLockState` (single instance) → `LocalPrivacyLockState` (Map) + `lockStateFor(scope)` accessor. - `redactionLevel` → `dmRedactionLevel` (Kotlin-side rename; persisted prefs key `redaction_level_ordinal` unchanged). - `setPasswordHashed(null)` cascades to `setLockEnabled(false)` so a master lock cannot stay armed without a credential to verify against. MessagesLockGate, DesktopMessagesLockGate, MessagesFirstRunBanner, SetPasswordDialog, and RedactionCard now read `lockStateFor(Messages)` — behaviour-preserving.

Balance StateFlow keeps last-known value. NWC responses continue to arrive on the coroutine scope; UI just doesn't render them until unlock. Honest and matches messaging behaviour. Called out in §Known Limitations. | +| App killed mid-unlock leaves Wallet stuck at Locked | State is in-memory; cold start re-reads `lockEnabled(Wallet)` from prefs → if enabled, starts Locked. Fail-safe. | +| User toggles Wallet off while Locked | `settings.lockEnabled(Wallet) → false` flows into `PrivacyLockState` which transitions `Locked → Disabled` on the next tick. Gate transparently shows content. Matches messaging behaviour. | +| Both scopes Locked, user in middle of a send-payment flow | Send-payment happens **inside** an already-unlocked scope; if idle timer fires mid-flow, the dialog stays composed (rememberSaveable) but the content behind is gated. Intentional — do not exempt in-flight payment dialogs from the timer. Manual test: `payment_flow_survives_timer.md`. | +| Concurrent leave-route events (Wallet + Messages navigating away simultaneously) | Each `PrivacyLockState` has its own idle-timer Job; no cross-scope races. | + +### API Surface Parity + +| Surface | Affected? | Notes | +|---|---|---| +| Android wallet UI (`OnchainSection`, `AddCashuWalletScreen`) | Deferred to v2 | Not touched in this plan — see §Future Considerations. | +| `amy` CLI | Not touched | CLI does not surface NWC actions today; when it does, use `PrivacyLockSettings.lockEnabled(Wallet)` for parity. | +| `UpdateZapAmountDialog.authenticate()` (nsec-key-guard biometric prompt) | Not affected | Separate OS-credential gate on the zap-amount-preferences change flow. Wallet gate is orthogonal — zap flow already gates OS credentials for a stronger reason. | +| One-click zap from a note (`ReactionsRow.RenderZapButton`) | Not gated | Wallet **column** is gated; zap **action** from feed context is not. Matches messaging: Messages **column** is gated; DM replies from a note thread are not (there aren't any). | +| Wallet notifications (NWC `success`, `failed`) | None on Desktop today | Desktop has no notification pipeline for wallet events. If added, use `redactionLevel` — but v1 keeps redaction Messages-only per §Proposed Solution. | +| Search results — NWC receipts / on-chain zaps | Not affected | `SearchBarViewModel` search-audit path from messaging plan already filters kinds 4/14/1059/443. NWC events (kind 23194/23195/23196) aren't searchable today. If they become searchable, add them to the audit list. | + +### Integration Test Scenarios + +1. **Cross-scope lockout**: Wallet locked. User enters 5 wrong + passwords on Wallet screen. Then navigates to Messages (also locked + via Messages toggle). Expected: Messages screen shows countdown + supportingText, `Unlock` button disabled. Failure mode: counter + scoped per-gate would defeat brute-force protection. +2. **Wallet lock + auto-fetched balance**: Wallet toggle just enabled; + user has been on Wallet column with balance loaded. Setting flip → + gate re-composes → balance is hidden behind the lock screen + **immediately**. Failure mode: balance visible for one frame during + transition. +3. **First-run banner interaction**: Fresh install → Messages column + visited → Messages banner shown, dismissed. User visits Wallet → + Wallet banner shown independently (not shared dismissal). Failure + mode: shared `firstRunCardSeen` would suppress Wallet banner. +4. **Toggle-disable while Locked**: User is on the Wallet lock screen → + opens Settings → Privacy lock → toggles Wallet off → returns to + Wallet. Expected: content shows without unlock. Failure mode: state + stays Locked because the settings update didn't cascade. +5. **NWC connect flow while locked**: New user, no NWC connected, + Wallet toggle on. Expected: `WalletColumnScreen`'s connect UI is + gated behind the lock — a Locked-gate does not let unauth users + trigger NWC pairing. Desired security posture. +6. **Password change → shared re-verify**: User changes password while + only Messages is locked. Then enables Wallet. Wallet lock screen + accepts the **new** password (not the old one). Failure mode: two + password hashes cached separately. +7. **Migration from legacy prefs**: User on a build with the shipped + `feat/desktop-privacy-lock` (single `lock_enabled` key) upgrades to + this build. Expected: Messages toggle preserved; Wallet toggle + defaults off. Legacy prefs keys removed; `schema_version = 2` + written. Failure mode: users get silently un-locked on upgrade, OR + migration re-runs and clobbers a subsequent Wallet toggle. + +## Acceptance Criteria + +### Functional + +- [ ] `LockScope` enum shipped in `commons/commonMain` +- [ ] `PrivacyLockState` replaces `MessagesLockState`; each scope has an + independent `state: StateFlow` and idle-timer Job +- [ ] `PrivacyLockSettings.lockEnabled` and `firstRunCardSeen` are + scope-accessor functions +- [ ] Password / inactivity timer / redaction / failed-attempts / lockout + remain device-global (shared) +- [ ] `MessagesLockGate` public signature unchanged; wired to + `lockStateFor(Messages)` +- [ ] `WalletLockGate` composable shipped in + `commons/.../ui/privacylock/` +- [ ] Shared `LockScreen(scope, title, subtitle, unlockLabel)` composable + replaces the inlined lock screen inside MessagesLockGate; both + gates render it +- [ ] `DesktopMessagesLockGate` unchanged in behaviour; consumes the new + shared `LockScreen` +- [ ] `DesktopWalletLockGate` shipped; wraps `WalletColumnScreen` inside + `DeckColumnContainer` +- [ ] `MessagesFirstRunBanner` unchanged in behaviour +- [ ] `WalletFirstRunBanner` shipped at top of `WalletColumnScreen` +- [ ] Settings screen renders two toggles + shared password subtree + + shared inactivity timer + Messages-only redaction card +- [ ] Legacy prefs migration runs on first startup after upgrade — old + `lock_enabled` value moved to `lock_enabled_Messages`, then old key + removed; `schema_version = 2` written +- [ ] `applyWindowCaptureBlock(true)` engages when either lock is enabled + AND the corresponding route is visible +- [ ] Blur-on-unfocus overlay renders over Wallet column when window + loses focus AND `lockEnabled(Wallet) == true` + +### Non-Functional + +- [ ] No measurable startup regression (≤ +5 ms cold start on top of + messaging-lock baseline) +- [ ] `PrivacyLockState.state` reads are constant-time regardless of + scope count (Map lookup, no reflection) +- [ ] No new deps added — everything stays inside kotlinx.coroutines + + Compose + the existing java.util.prefs / SharedPreferences setup +- [ ] Password comparison stays constant-time via `PasswordHasher.verify` + (unchanged) +- [ ] No visible flash of Wallet content on cold start when + `lockEnabled(Wallet) = true` — seeded synchronously (deep-link race + fix H1 from messaging plan applies to both scopes) + +### Quality Gates + +- [ ] `./gradlew :commons:jvmTest --tests "*privacylock*"` green (8 tests) +- [ ] `./gradlew :amethyst:assembleDebug` green +- [ ] `./gradlew :desktopApp:compileKotlin` green +- [ ] `./gradlew :desktopApp:packageDmg` green on macOS host +- [ ] `./gradlew :desktopApp:packageMsi` green on Windows host (best effort) +- [ ] `./gradlew :desktopApp:packageDeb` green on Linux host +- [ ] `./gradlew spotlessApply` clean +- [ ] Manual testing sheet + (`docs/plans/2026-07-07-wallet-lock-manual-testing.md`) executed + and signed off + +## Success Metrics + +- **Adoption proxy**: after 30 days on nightly, at least half the users + who enabled the Messages lock have also enabled the Wallet lock.

Use NIP-65: index relays discover each author's kind-10002, then per-author kind 0/3 REQs go to that author's declared write relays. New in commons/commonMain: - OutboxCacheGateway — platform-agnostic bridge to the local event cache. Three ops: cachedOutbox(pubkey), onOutboxDiscovered(event, relay), onDiscoveredEvent(event, relay). - OutboxDispatcher — three-phase pipeline reusing Quartz's existing RelayListRecommendationProcessor.reliableRelaySetFor(...) for the author→relay inversion + minimal-cover algorithm. Phase 1: REQ kind-10002 for authors not already cached, from index relays. Per-relay 4s timeout. Phase 2: reliable-relay-set → per-outbox-relay REQ for kind 0 and/or kind 3 filtered to that relay's authors. Phase 3: index-relay fallback for authors that never returned a 10002. Preserves current behaviour on cold accounts. Retries the "not in kind*Succeeded and not in kind*InFlight" set so a zero-EOSE run is retryable on the next call. New in DesktopLocalCache: - route() branch for AdvertisedRelayListEvent (kind 10002) storing in addressableNotes so cachedAdvertisedRelayList(pubkey) can serve future lookups without a REQ. - cachedAdvertisedRelayList(pubkey): AdvertisedRelayListEvent? — the gateway's peek into the cache for Phase-1 skipping. Tests (7): cached-outbox-skips-Phase-1, Phase-1-discovers-then-Phase-2, Phase-3-fallback-for-no-10002, cached-author-covered-when-Phase-1-hangs, clear-releases-dedup, concurrent-EOSE-safety.

The WoT service's kind-3 seeding on Desktop and the `amy wot sync` verb now go through OutboxDispatcher — index relays discover each author's kind-10002 write relays, then per-outbox-relay REQs fetch kind-3. Changes: Desktop: - DesktopRelaySubscriptionsCoordinator gains an inner OutboxCacheGateway that bridges DesktopLocalCache (cachedAdvertisedRelayList / consume) to OutboxDispatcher. - New suspend loadKind3ViaOutbox(pubkeys) method returns the dispatcher's Result for observability. - Main.kt WoT-seed effect now: 1. gates on wotService.isDisabled to preserve MAX_FOLLOWS guardrail (fix 2 from Phase 1) 2. calls loadKind3ViaOutbox instead of the direct loadKind3Batched on index relays 3. keeps the 2s markReady safety net for cold-start UX - clear() now also clears outboxDispatcher's dedup markers. amy: - WotCommand.sync rewritten to construct an OutboxDispatcher, buffer events in the gateway, and persist to ctx.store after fetch returns (store.insert is suspending; can't call from non-suspend gateway callbacks). - --json output additively gains kind10002_received, outbox_covered_authors, fallback_authors, persisted keys. - --timeout N still supported; now maps to overallTimeoutMs. Not in this commit (deferred to a follow-up on same PR if reviewers want it): - Routing stranger-avatar kind-0 fetch through the outbox path (MetadataPreloader wiring is more invasive; keeps this diff focused on the primary WoT concern).

Every relay starts generous (100 concurrent subscriptions) and is demoted down a ladder (100 -> 20 -> 10) only when it complains about concurrency — a CLOSED rate-limited, or a NOTICE like "too many concurrent REQs" / "too many subscriptions" / "burst exhausted". Well-behaved relays keep the full cap; only the busy hubs that push back get throttled, and only as far as they keep pushing. AdaptiveRelayLimiter registers as a RelayConnectionListener so demotions are driven straight off the same NOTICE/CLOSED frames RelayDiagnostics already observes, keyed by relay.url. Context.drain gains a gatePerRelay path that opens one subscription per relay, each held behind that relay's gate, so our concurrent subs on it never exceed its current cap. The gate is a fair FIFO bounded semaphore whose limit can only be lowered; shrinking below the in-use count admits no new subs until enough finish, so concurrency converges down to the new cap. Because a hot relay can no longer be flooded, the global content-drain fan-out is raised (18 -> 48) to crawl the many well-behaved relays faster. The crawl emits a relay_throttling summary (which relays were capped, and to what) alongside relay_feedback. --- .../amethyst/cli/AdaptiveRelayLimiter.kt | 198 ++++++++++++++++++ .../com/vitorpamplona/amethyst/cli/Context.kt | 115 ++++++++++ .../amethyst/cli/commands/GrapeRankCommand.kt | 33 +-- 3 files changed, 332 insertions(+), 14 deletions(-) create mode 100644 cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/AdaptiveRelayLimiter.kt diff --git a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/AdaptiveRelayLimiter.kt b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/AdaptiveRelayLimiter.kt new file mode 100644 index 0000000000..d57e19c034 --- /dev/null +++ b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/AdaptiveRelayLimiter.kt @@ -0,0 +1,198 @@ +/* + * Copyright (c) 2025 Vitor Pamplona + * + * Permission is hereby granted, free of charge, to any person obtaining a copy of + * this software and associated documentation files (the "Software"), to deal in + * the Software without restriction, including without limitation the rights to use, + * copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the + * Software, and to permit persons to whom the Software is furnished to do so, + * subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS + * FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Every relay WS-upgrade handshake is an async call through that shared dispatcher, so 64 caps the connection-ramp width — and a dead relay squats on a slot for the full connectTimeout, starving live relays queued behind it (observed: only ~150 sockets open at once during an active wave touching hundreds of relays). Raise maxRequests to 256 / maxRequestsPerHost to 16 and drop connectTimeout to 5s so unreachable relays release their slot fast. This is orthogonal to REQ concurrency (bounded per-relay by AdaptiveRelayLimiter on already-open sockets), so it can't trip a relay's REQ rate-limit — it only speeds connection setup. The dispatcher's executor pool grows threads on demand, and FD headroom is ample (4096 limit vs ~150 in use), so the wider cap just lets more short-lived handshakes run at once. --- .../com/vitorpamplona/amethyst/cli/Context.kt | 25 ++++++++++++++++++- 1 file changed, 24 insertions(+), 1 deletion(-) diff --git a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt index b44075ad6a..8ce736de36 100644 --- a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt +++ b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt @@ -78,8 +78,10 @@ import kotlinx.coroutines.joinAll import kotlinx.coroutines.launch import kotlinx.coroutines.selects.select import kotlinx.coroutines.withTimeoutOrNull +import okhttp3.Dispatcher import okhttp3.OkHttpClient import java.util.concurrent.ConcurrentHashMap +import java.util.concurrent.TimeUnit /** * Per-invocation wiring.

Fetch kind:10002 alongside content. The content query asked only for 3/10000/1984, so a user's freshest relay list — which lives on their own outbox — was never pulled from there; we trusted a possibly-stale indexer copy. Fold 10002 into the same fetch. The store keeps newest-by-created_at, so pulling it from popular relays too can't stale it. 2. Widen ensureRelayLists Tier 2. It only asked the top-30 backbone for a still-missing 10002. A stray relay list can sit on any one relay, so Tier 2 now asks EVERY relay we've seen work — fired fire-and-forget on a background scope so the large fan-out never blocks the round; results enrich routing for later rounds. 3. Classify dead relays instead of striking everything the same. A connect TIMEOUT is a busy relay — retried, never marked dead. A HARD failure (bad domain, TLS misconfig, dead HTTP code — see DrainFailure/classifyDrainFailure, keyed on the exception type now in the failure message) is dropped on the first strike. Transient failures (refused/reset/unreachable, 429/5xx) keep the multi-strike leniency.

Refactor: build one filterMap keyed by recommendation.relay and issue a single client.subscribe. All relays fan out in parallel; the per-relay EOSE gate bounds the wait regardless of set size. Phase 3 fallback gets the same shape for consistency. Also: - Bump overallTimeoutMs default from 8s -> 20s (belt only; parallel Phase 2 makes it unlikely to trip). - Log OVERALL TIMEOUT when withTimeoutOrNull returns null so reviewers can distinguish 'ran fine, no data' from 'timed out'. - Add per-phase debug logs (start / phase1 done / phase2 recommendations and done / phase3 fallback and done) so the outbox pipeline is auditable without a debugger.

Errors clearly if unset. - Three-way reconciliation against what the provider key already published: upsert cards whose rank tag string changed (or are new), skip unchanged, and RETRACT (kind:5, same service key, addressable `a`-tag, chunked under the message cap) any existing card whose target is no longer publishable — dropped from the graph, or below the cutoff. - Raise the default publish cutoff to rank >= 2 (drops the barely-trusted tail); the retract rule removes any now-sub-cutoff cards. - When we hold the observer's key (observer == active account), publish/refresh their kind:10040 pointing 30382:rank -> providerPubkey at the operator relay, to their outbox — the pointer clients follow to find the cards.

Move it into a reusable, KMP-portable GrapeRankDataCrawler in quartz commonMain. The crawler takes a NostrClient + IEventStore + AdaptiveRelayLimiter, injected relay policy (discovery + content-fallback sets, since those defaults live in app code, not the protocol library), and a log callback; it streams contact lists into a TrustGraphBuilder and returns crawl Stats. GrapeRankCommand shrinks to arg-parsing + offline load + scoring + publish + sub-verbs, delegating the online path to the crawler. To reach commonMain (portable to every target, incl. iOS): - Add ConcurrentMap / ConcurrentSet expect classes under utils/concurrent, with jvmAndroid actuals (java.util.concurrent) and native actuals (copy-on-write over kotlin.concurrent.atomics.AtomicReference, mirroring ConcurrentHashCache). commonMain has no ConcurrentHashMap, and the crawl's producer/consumer/drain- worker state needs atomic getOrPut/merge plus a concurrent set. - Move AdaptiveRelayLimiter and DrainFailure/classifyDrainFailure from cli to quartz commonMain (java atomics -> kotlin.concurrent.atomics, ConcurrentHashMap -> ConcurrentMap, System.currentTimeMillis -> TimeUtils.nowMillis, stderr -> Log). - The gated drain (REQ-size splitting, per-relay permits, verify+store) moves into the crawler; Context.drain loses its now-unused gatePerRelay path. Net: cli -1077 lines; the crawler + relay machinery are now reusable by the Android app. Adds ConcurrentCollectionsTest; verified via JVM + commonMain metadata compile, the wot/graperank suites, and a bounded live crawl. --- .../com/vitorpamplona/amethyst/cli/Context.kt | 217 +---- .../amethyst/cli/commands/GrapeRankCommand.kt | 639 +------------- .../graperank/GrapeRankDataCrawler.kt | 813 ++++++++++++++++++ .../accessories}/AdaptiveRelayLimiter.kt | 72 +- .../relay/client/accessories/DrainFailure.kt | 77 ++ .../quartz/utils/concurrent/ConcurrentMap.kt | 68 ++ .../quartz/utils/concurrent/ConcurrentSet.kt | 43 + .../concurrent/ConcurrentCollectionsTest.kt | 108 +++ .../concurrent/ConcurrentMap.jvmAndroid.kt | 51 ++ .../concurrent/ConcurrentSet.jvmAndroid.kt | 35 + .../utils/concurrent/ConcurrentMap.native.kt | 80 ++ .../utils/concurrent/ConcurrentSet.native.kt | 46 + 12 files changed, 1406 insertions(+), 843 deletions(-) create mode 100644 quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/experimental/graperank/GrapeRankDataCrawler.kt rename {cli/src/main/kotlin/com/vitorpamplona/amethyst/cli => quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip01Core/relay/client/accessories}/AdaptiveRelayLimiter.kt (80%) create mode 100644 quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip01Core/relay/client/accessories/DrainFailure.kt create mode 100644 quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentMap.kt create mode 100644 quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentSet.kt create mode 100644 quartz/src/commonTest/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentCollectionsTest.kt create mode 100644 quartz/src/jvmAndroid/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentMap.jvmAndroid.kt create mode 100644 quartz/src/jvmAndroid/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentSet.jvmAndroid.kt create mode 100644 quartz/src/nativeMain/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentMap.native.kt create mode 100644 quartz/src/nativeMain/kotlin/com/vitorpamplona/quartz/utils/concurrent/ConcurrentSet.native.kt diff --git a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt index 4214dac422..531fcbf6c5 100644 --- a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt +++ b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt @@ -41,6 +41,9 @@ import com.vitorpamplona.quartz.nip01Core.core.hexToByteArray import com.vitorpamplona.quartz.nip01Core.crypto.verify import com.vitorpamplona.quartz.nip01Core.metadata.MetadataEvent import com.vitorpamplona.quartz.nip01Core.relay.client.NostrClient +import com.vitorpamplona.quartz.nip01Core.relay.client.accessories.AdaptiveRelayLimiter +import com.vitorpamplona.quartz.nip01Core.relay.client.accessories.DrainFailure +import com.vitorpamplona.quartz.nip01Core.relay.client.accessories.classifyDrainFailure import com.vitorpamplona.quartz.nip01Core.relay.client.accessories.fetchAllPagesFromPool import com.vitorpamplona.quartz.nip01Core.relay.client.accessories.publishAndConfirmDetailed import com.vitorpamplona.quartz.nip01Core.relay.client.auth.RelayAuthenticator @@ -74,86 +77,13 @@ import kotlinx.coroutines.CompletableDeferred import kotlinx.coroutines.channels.Channel import kotlinx.coroutines.channels.Channel.Factory.UNLIMITED import kotlinx.coroutines.coroutineScope -import kotlinx.coroutines.joinAll import kotlinx.coroutines.launch import kotlinx.coroutines.selects.select import kotlinx.coroutines.withTimeoutOrNull import okhttp3.Dispatcher import okhttp3.OkHttpClient -import java.util.concurrent.ConcurrentHashMap import java.util.concurrent.TimeUnit -/** - * Why a relay could not be used for a drain — when the reason is worth acting on. - * - * - [HARD]: the relay answered wrong, or cannot exist.

The frontier is now `hopOf.keys`; one fewer collection to keep in sync. - Drop the unused `Stats.discovered` / `Stats.deadRelays` fields (no reader — the CLI reports rounds / relaysContacted / hopHistogram / downloadMs). - Extract a single shared verify-then-store sink, `IEventStore.verifyAndInsert`, and route both the crawler and `Context.verifyAndStore` through it instead of each carrying its own verify + insert + UNIQUE-swallow copy. - Fast-path the present-key hit in `ConcurrentMap.getOrPut` (jvmAndroid) so the crawl's hot relay-hint accumulation stops allocating a mapping-function closure on every call. - Hoist the repeated `crawlStats?.hopHistogram` null-plumbing in GrapeRankCommand. --- .../com/vitorpamplona/amethyst/cli/Context.kt | 39 +++-------- .../amethyst/cli/commands/GrapeRankCommand.kt | 5 +- .../graperank/GrapeRankDataCrawler.kt | 68 ++++++------------- .../quartz/nip01Core/store/VerifyAndInsert.kt | 55 +++++++++++++++ .../concurrent/ConcurrentMap.jvmAndroid.kt | 6 +- 5 files changed, 94 insertions(+), 79 deletions(-) create mode 100644 quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip01Core/store/VerifyAndInsert.kt diff --git a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt index 531fcbf6c5..e75e8459df 100644 --- a/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt +++ b/cli/src/main/kotlin/com/vitorpamplona/amethyst/cli/Context.kt @@ -38,7 +38,6 @@ import com.vitorpamplona.quartz.marmot.mip03GroupMessages.GroupEvent import com.vitorpamplona.quartz.nip01Core.core.Event import com.vitorpamplona.quartz.nip01Core.core.HexKey import com.vitorpamplona.quartz.nip01Core.core.hexToByteArray -import com.vitorpamplona.quartz.nip01Core.crypto.verify import com.vitorpamplona.quartz.nip01Core.metadata.MetadataEvent import com.vitorpamplona.quartz.nip01Core.relay.client.NostrClient import com.vitorpamplona.quartz.nip01Core.relay.client.accessories.AdaptiveRelayLimiter @@ -58,6 +57,7 @@ import com.vitorpamplona.quartz.nip01Core.relay.sockets.okhttp.TcpNoDelaySocketF import com.vitorpamplona.quartz.nip01Core.signers.NostrSigner import com.vitorpamplona.quartz.nip01Core.signers.NostrSignerInternal import com.vitorpamplona.quartz.nip01Core.store.IEventStore +import com.vitorpamplona.quartz.nip01Core.store.verifyAndInsert import com.vitorpamplona.quartz.nip02FollowList.ContactListEvent import com.vitorpamplona.quartz.nip17Dm.settings.ChatMessageRelayListEvent import com.vitorpamplona.quartz.nip46RemoteSigner.signer.NostrSignerRemote @@ -688,36 +688,17 @@ class Context( } /** - * Verify [event]'s NIP-01 id+signature and, if valid, persist it - * to [store].

Add a crawl-wide seen-set (thread-safe ConcurrentSet of event ids, shared across all 24 concurrent drains and every round), checked before verify and added only after verify so a forged copy can't suppress the genuine one. Group-commit the store writes via IEventStore.batchInsert instead of one transaction per event. Measured on a from-scratch --max-hops 3 crawl: events actually verified+stored dropped ~34% (112k -> 74k) and verify time fell in lockstep.

It takes an IEventStore for the prior-card read-back and an injected publish function (event + relays -> per-relay ack), so the store/relay wiring stays in the app while the reconcile logic is reusable (e.g. by the Android app). GrapeRankCommand is now a thin orchestrator: crawl (GrapeRankDataCrawler) -> score (GrapeRank) -> publish (GrapeRankPublisher).

Distinguish the cases: drainGated now reports the relays that fully EOSE'd (answeredOut); the consumer records, per user, the relays that answered but did not return their contact list (askedEmpty); routeByOutbox excludes those from the user's candidate relays. A timed-out relay is never added (it might just be slow — still worth a retry), only a clean-EOSE-empty one; dead relays stay pruned as before. Measured on --max-hops 3: redundant fetching dropped ~8% (74k -> 68k events stored). It does NOT move the wall-clock tail, though — that tail is dominated by timeout/dead outboxes (the retryable case), not EOSE-empty relays. The wall-clock lever remains the timeout retry budget (MAX_OUTBOX_ATTEMPTS / drain timeout). --- .../graperank/GrapeRankDataCrawler.kt | 73 ++++++++++++++++--- 1 file changed, 62 insertions(+), 11 deletions(-) diff --git a/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/experimental/graperank/GrapeRankDataCrawler.kt b/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/experimental/graperank/GrapeRankDataCrawler.kt index 132690ee81..02c791ebfa 100644 --- a/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/experimental/graperank/GrapeRankDataCrawler.kt +++ b/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/experimental/graperank/GrapeRankDataCrawler.kt @@ -196,6 +196,13 @@ class GrapeRankDataCrawler( // (valid id, bad signature) delivered first can't suppress the genuine one. val seenIds = ConcurrentSet() + // Per-user relays that answered (EOSE'd) without holding this user's kind:3, + // so re-querying them for this user is guaranteed-empty waste. routeByOutbox + // subtracts these from a user's candidate relays, so a straggler is retried + // only against relays that could plausibly still have it (never-asked, or + // ones that timed out — which unlike a clean EOSE might just be slow). + val askedEmpty = ConcurrentMap>() + var rounds = 0 var contactListsFed = 0 @@ -456,9 +463,15 @@ class GrapeRankDataCrawler( (attempts[pk] ?: 0) > 0 -> write + backbone else -> write } - // Skip relays already proven dead — routing to them only burns the - // drain timeout. - for (relay in relays) if (relay !in deadRelays) perRelay.getOrPut(relay) { HashSet() }.add(pk) + // Skip relays proven dead (routing to them only burns the drain + // timeout) and relays that already EOSE'd without this user's list + // (re-querying them for this user is guaranteed-empty waste). + val emptied = askedEmpty[pk] + for (relay in relays) { + if (relay in deadRelays) continue + if (emptied != null && relay in emptied) continue + perRelay.getOrPut(relay) { HashSet() }.add(pk) + } } return perRelay.mapValues { (_, authors) -> @@ -515,7 +528,7 @@ class GrapeRankDataCrawler( // only on the consumer (keeps done/builder/hopOf serial), now // overlapped with draining instead of blocked behind each batch. val routed = Channel, Map>>>(DRAIN_CONCURRENCY * 2) - val drainedOut = Channel, Set, List>>>(Channel.UNLIMITED) + val drainedOut = Channel(Channel.UNLIMITED) coroutineScope { // Producer: route each batch by outbox (serial), backpressured // by the bounded `routed` channel. @@ -528,26 +541,44 @@ class GrapeRankDataCrawler( routed.close() } // Drain workers: pure network, no shared graph-state writes - // except recordDead (concurrent-safe). + // except recordDead (concurrent-safe).

This lets a human replay that precise REQ later to understand why the relay lags. Gated on --diagnose so there is no per-group timing/collection overhead otherwise. Make the content-drain fan-out configurable via a new --drain-concurrency flag (Config.drainConcurrency), replacing the DRAIN_CONCURRENCY constant. Default stays at the validated 24: an A/B at 64 ran ~2x slower with more dead relays (a higher global fan-out re-floods busy hubs faster than the per-relay demotion catches up), so the flag is a probe knob, not a speedup. Client WebSocket pings were also tried and reverted — busy-but-alive relays don't reliably pong while their query handler runs, so pinging just cut them as dead.

That made waiting for slow-but-alive relays expensive — every hop paid its slow tail before the next hop's fast relays could begin — so a long timeout for completeness cost ~2x wall-clock (measured), and a short one dropped the slow relays' data. Diagnostics on a ~190k-user crawl showed the genuinely-slow set is a stable ~30 relays that DO reach EOSE, just in 5-25s. So decouple the two concerns: - drainGated now drains on the FAST `timeoutMs` that sets the round cadence. A relay still streaming when it elapses is not cut but PARKED: it hands its open subscription to a background scope (releasing its AdaptiveRelayLimiter permit so the round moves on), keeps receiving for up to the new `parkTimeoutMs`, and its late events are persisted + its late contact lists pushed to a crawl-wide lateHarvest channel. - The round loop folds late harvest into the graph between rounds and won't converge until the frontier is empty AND no relay is still parked — so the crawl waits for slow relays for completeness without paying that wait in each round's wall-clock. Graph state stays single-writer: parked coroutines only touch the store, seenIds, and the channel — never hopOf/done/builder. Persistence moved from a single per-drain consumer to a shared `persist()` that fast and parked units both call; crawl-wide dedup is now race-safe via ConcurrentSet.add's atomic test-and-set (an id is added only after a good signature, so no duplicate reaches the store's UNIQUE constraint and a forged copy can't suppress the genuine one). Also carries the --diagnose slow-relay logging (relay + filter + elapsed for every slow/parked REQ, so a human can replay it) and keeps --drain-concurrency at the validated default of 24 (an A/B at 64 was ~2x slower with more dead relays). New --park-timeout flag (default 40s; set <= --timeout to disable).

Other accounts' cached events are left untouched. `--keep-events` skips the shared-cache purge entirely. The public key is read straight from identity.json (never unlocking the private key), so logoff needs no passphrase and pops no keychain prompt. Destructive and irreversible, so it follows the `marmot reset` precedent: `--yes` is required to execute; without it the command prints a dry run of what would be deleted and exits 2. Thin-assembly only — event deletion is quartz's FsEventStore.delete; this just resolves the account, counts, and wires the filesystem teardown.

Reads now work anonymously; only signing needs an account: - `DataDir.resolveOptional` hands back an accountless dir (`hasAccount = false`) pointing only at the shared event store when there is no unambiguous account, instead of throwing. - `Context.openOrAnonymous` uses the resolved account when present, else an ephemeral key-less `Identity.anonymous()` — can read, can't sign. Marmot stores are now lazy and run-state isn't persisted for anonymous runs, so an accountless read leaves `~/.amy/shared/` clean. - `Context.open` (signing path) re-asserts the requirement with the "which account?" hint, so ambiguous/no-account signing verbs still exit 2. - Main resolves optionally for every verb except the identity-lifecycle ones (`init`/`create`/`login`/`logoff`/`whoami`), which still need a concrete account. `offer info` / `debit info` join the stateless primitive block. - Read subverbs (fetch, subscribe, count, publish, outbox, search, sync, store, profile/git/podcast/podcast20 reads, nsite/napplet fetch·serve·list, blossom download·check) switch to `openOrAnonymous`. No `--json` shapes change. Docs updated (help text, README, DEVELOPMENT).

Add a heartbeat ticker on the background scope that emits every few seconds with the current round's completion (a real X/Y % against the round's known pending target), a rolling fetch rate + rough ETA for it, and live counts (events stored, relays parked/dead) — and a "finishing" line while draining the parked tail. Scoring stays sub-second, so it keeps its per-sweep lines and needs no ticker. Also make crawl()'s builder nullable: null runs a persist-only pass (every event still lands in the store, the frontier still expands off each contact list) with no in-memory graph — the basis for a `sync` that loads data without scoring.

Bare `amy graperank` stays the sync+score combo. Extract the shared crawler wiring into newCrawler(); score() just forces the offline path, and sync() runs a persist-only crawl (null builder).

The homebrew-core auto-bump is deferred (documented TODO) because brew bump-formula-pr can only bump a formula already in the tap, and amy has not been submitted to homebrew-core yet. Also fix the "Report failure" step in bump-homebrew.yml and bump-winget.yml: both declared `permissions: contents: read`, but github.rest.issues.create needs issues:write, so the failure reporter itself 403'd and never filed an alert. Add issues:write to both.

Add a deletion side-channel that reconciles kinds 5 & 62 on their own, independent of the content filter. quartz: NostrClientDeletionSyncExt — DELETION_PROPAGATION_KINDS, Filter.excludesDeletionKinds()/deletionSideChannelFilter() (kinds 5/62 scoped to the same authors, no time window since a deletion's created_at is not its target's), shouldPropagateDeletionUp() (kind-5 always; kind-62 only to a relay it targets, honoring the vanish's declared relays), and negentropyPropagateDeletions() — one bidirectional reconcile that streams have→upload and need→download. amy sync: run the side-channel bidirectionally regardless of --up/--down whenever the filter excludes 5/62; emits deletions_{need,have,downloaded, uploaded}; --no-sync-deletions opts out. geode MirrorWorker: thread a per-upstream deletionScope through both catch-up phases and both live subs (down + up), in the mirror's configured direction; relax down containment to accept in-scope deletions, gate kind-62 pushes by target relay, and carry the deletion filter on re-subscribe so a reconnect never drops it. Tests: DeletionSyncTest (up/down propagation + filter/vanish-gate units) and MirrorDeletionSyncTest (a kind-scoped down mirror still removes the note).

Deletion side-channel now runs FIRST, before content, in both directions. The content snapshot is taken AFTER it, closing a resurrection bug: a deletion pulled down mid-sync removes a local event, but the old top-of-run snapshot still listed it and would re-offer it up — resurrecting it on a relay that also lacked the deletion. 2. Content reconcile, over the post-deletion snapshot. 3. Reject-reaction backstop: when the relay blocks a content push (usually it holds a deletion we lack), pull that author's kind-5/62 and ingest locally so we stop re-offering the dead event. Verify-by-fetch — only a real deletion the store accepts has any effect; fires only on an actual reject. The up-push of deletions is already verified per-event: ctx.publish awaits the relay's OK, and ingesting the kind-5 runs the delete synchronously, so OK=true confirms the remote applied it. Mirror catch-up gets the same deletions-first ordering (down and up), so a deletion lands, or the reject-trigger is armed, before its target — no add-then-delete churn. Tests: MirrorDeletionSyncTest gains scopedUpMirrorPushesDeletion (authoritative push — local holds the deletion, remote drops the note).

Root cause: deletionSideChannelFilter fell open to authors=null for any non-author-scoped content sync, so `amy sync --kind 1` reconciled the RELAY'S ENTIRE kind-5/62 history and applied it to the personal FsEventStore — every kind-5 deleting its targets + installing an id-tombstone for every target id, every ALL_RELAYS kind-62 wiping all of a pubkey's events (all kinds), and pushing our whole local deletion history up. Data loss plus a full-history reconcile on every scoped sync. Fixes: - Bound the side-channel to the authors we actually hold content for (filter authors ∪ local matched-set authors), never the relay's population. Skip when that scope is empty; Phase 3's reject-reaction covers the author-less case. - Kind-5 (precise, owner-scoped) propagates by default; kind-62 vanish is opt-in via --sync-vanish (its blast radius always exceeds a content sync's scope). - excludesDeletionKinds() now checks each deletion kind independently (`--kind 1,5` no longer silently drops kind-62); the side-channel reconciles only the missing kinds. - amy Phase 1 is best-effort: a deletion-reconcile failure records deletions_error and falls through to content, never aborting the primary sync (matches geode). - Mirror up-catch-up converges on whether a PUBLISHABLE event was pushed, not raw haveCount — a vanish targeting another relay no longer burns all 8 rounds every startup. Mirror keeps its (correct) global scope for relay-to-relay replication. Helper API: negentropyPropagateDeletions gains scopeAuthors + deletionKinds; deletionSideChannelFilter takes authors + deletionKinds and returns only the missing kinds. Tests updated for the new semantics.

Only the need ids, only kind-5, up only. This removes all the machinery the earlier approach accreted and that the audit flagged as over-broad / data-loss-prone: - deleted NostrClientDeletionSyncExt (the bidirectional side-channel, author scoping, vanish gating, kind selection); - reverted geode MirrorWorker to base (no deletion side-channel, live-sub changes, catch-up ordering, or convergence changes); - dropped the 3-phase SyncCommand flow (deletions-first pull, author-scope derivation, reject-reaction backstop, --sync-vanish, deletions_* output). The new path pulls nothing down and applies nothing locally, so it cannot over-delete the store, and it needs no author scoping — the need set already bounds it. Kind-62 is intentionally excluded: a vanish is not "of an id". Emits deletions_sent. DeletionSyncTest now exercises the exact wiring (reconcile → look up local kind-5 by its e tag for the need ids → publish), including the negative case (a need id we never had sends nothing).

Determining coverage needs the need event's author/address/created_at, which we don't have for an id we lack, so we fetch the need events (raw — no verify, no store) purely for metadata. quartz gains IEventStore.deletionsCovering(events, relay), which maps server-held events to the covering local deletions across all three forms: - NIP-09 id-based: a kind-5 with an `e` tag naming the event id; - NIP-09 address-based: a kind-5 with an `a` tag naming the event's addressable/replaceable coordinate, at/after it (created_at <= deletion); - NIP-62 vanish: a kind-62 by the event's author, targeting this relay, issued after it (created_at < vanish). SyncCommand's need workers now fetch each need batch once (Context.fetchRaw), publish its covering deletions (deduped across workers), and — when --down — store the rest; anything we deleted is rejected by the store's own tombstone. Nothing is pulled down or applied locally, so it cannot over-delete the store. DeletionSyncTest covers each form (with cutoff and wrong-relay negatives) plus an end-to-end reconcile → cover → publish that removes the note on the relay.

The restored local member then re-emitted generation 0 within the same epoch — reusing the AEAD key+nonce (a confidentiality break) and getting rejected by strict receivers (openmls / MDK / Whitenoise) that forbid generation reuse, per RFC 9420 §9. Two parts: - Persist per-sender ratchet positions. SecretTree gains export/importSenderStates; MlsGroupState carries them as an optional field (STATE_VERSION 2, v1 blobs still decode as empty = legacy behavior); saveState/restore wire them through. - Persist after every send. MlsGroupManager.encrypt now saves group state, not just commits — application sends advance the ratchet but previously never hit the store, so a restart between two commits still reset it. Regression tests: a peer that consumed generation 0 accepts the restored sender's next message (single + multi-send), encrypt persists the ratchet between commits, and a v1 blob still decodes/restores.

Pass 1 is the plain content sync again (drain needs, publish haves) — zero deletion overhead. Pass 2+ re-reconciles; the leftover diff is exactly the deletion mismatches, and only that (tiny) set is fetched: - residual need (relay has it, we still lack it after --down) = we deleted it → publish our covering deletion up so the relay drops it; - residual have (we have it, relay still lacks it after --up) = the relay deleted it → pull the relay's covering kind-5 down and apply locally (vanish is NOT auto-applied on pull — account-wide blast radius). Loops until a round resolves nothing (converges + self-verifies). So `amy sync` makes the relay honor our deletions; `--up` makes us honor the relay's; `--up --down` converges both ways. Cost is one cheap reconcile + the residual regardless of database size — the large-DB bottleneck is gone by construction, not by heuristics. quartz: deletionsCovering is now source-agnostic (takes a query lambda) so the same coverage rule runs against the local store (up) or the relay (down); the IEventStore overload is the local convenience. Tests: DeletionSyncTest gains the down-direction end-to-end (relay deleted → local removes) alongside the up-direction and the per-form unit cases.

The outbox model makes this worse: one dead server (e.g. filter.nostr.wine) is advertised as hundreds of distinct per-user path URLs, so a per-URL counter never reaches a threshold on any single one. Count unproductive-timeout strikes per relay AUTHORITY (host[:port]) and evict the whole host after Config.timeoutEvictStrikes (default 3; CLI --timeout-evict, 0 disables). Any clean EOSE or delivered event clears the authority, so only never-productive hosts are evicted; a multi-path relay where some paths are slow but others deliver stays live. Authority is host-only and never folds a filter. subdomain into its parent, so an open bare host is untouched when its sibling filter host is shed. Purely behavior-driven — no NIP-11.

Returns DeletionSettleResult(sentUp, appliedDown, rounds). Everything it needs is already quartz (negentropyReconcileIds, fetchAll, deletionsCovering, publishAndConfirm, Event.verify, IEventStore), so it carries no CLI dependency. SyncCommand's pass 2 collapses to a single call; pass 1 (content) is unchanged. Catalogued in the accessories README. Tests: DeletionSyncTest drives the accessory end-to-end both ways (sendUp → relay converges to gone; applyDown → local converges to gone), on top of the existing deletionsCovering unit + manual-wiring cases.

charset=UTF-8 Content-Transfer-Encoding: 8bit relayBench measures relay-to-relay reconcile, not the amy/quartz client feature, so the deletion-settle perf claim belongs in an in-process benchmark of negentropySettleDeletions itself. Models the post-content-settle state: a relay with N notes, a local store with the same N except K it deleted (keeping the K kind-5s). The reconcile residual is exactly those K, so a sendUp settle fetches K — not N. Asserts residual==K, sentUp==K, and relay convergence (correctness guard at the small default N), and prints one-reconcile vs full-settle so the deletion overhead reads as "a few reconciles + K", never "+ a content re-download". Measured: N=2000 K=20: settle ~2x one reconcile, fetched K=20 not N N=100000 K=20: settle ~5x one reconcile, fetched K=20 not N=100000 The growth is the relay rebuilding its negentropy index after the deletions (O(N) once) — inherent to applying deletions, and still far cheaper than re-fetching the need set, which the old per-need-fetch approach did. Scale with -DdelBenchN / -DdelBenchK (forwarded by the geode test task).

But a large tail of reachable users have no kind:3 on their own advertised outbox at all — it's dead, or they never published one there — while a network-wide aggregator (user.kindpag.es, …) that scrapes the whole network holds it. Those aggregators were queried only for kind:10002 relay lists in ensureRelayLists, never for kind:3 content, so the crawl structurally could not find these lists no matter how many rounds it ran. Add Config.contentAggregatorRelays and fold it into routeByOutbox for stragglers — users whose own outbox already failed (attempts > 0) or is unknown. The CLI wires the profile indexers (kindpag/purplepag/coracle/yabu/nostr1) plus the ActivityPub bridges (ditto/momostr/mostr, which host bridged users' lists); --no-aggregators disables it. Measured offline on observer 460c25e6 (max-hops 3): of ~2.2k users the crawl left without a contact list, querying the aggregators for kind:3 recovers ~500 (user.kindpag.es alone ~180) — lifting coverage from ~89% toward ~92%. The remainder have no kind:3 retrievable on any relay we know (bridged / inactive / never-published) — a data-absence floor, not a crawl deficiency.

Root cause: during the competitive crawl an indexer like user.kindpag.es is only ever asked for kind:10002 in bulk and kind:[3,10000,1984,10002] one author at a time. The latter parks and times out (60-80s each), striking the host until its authority is timeout-evicted. It is never asked for a clean bulk kind:3 -- the one thing it serves fast (~19 lists per 300 authors in seconds; ~369 of the run's missing authors live there). So by the time recovery runs, kindpag.es is dead and dropped from the aggregator set (8 configured -> 6 used), and the biggest single source of missing lists is never queried. Fix: the recovery pass now queries every configured aggregator regardless of eviction (drainGated doesn't re-check isDead, and a genuinely dead endpoint only costs one shared park window since units run concurrently), and clears any timeout strikes first so a partially-struck host starts clean. Also stops folding aggregators into routeByOutbox's multi-kind fan-out (they time out there) and asks them kind:3-only, matching what they serve.

Measured: user.kindpag.es returns at most ~100 events per REQ and ignores our limit, so a dense chunk -- 300 authors × the 4 FETCH_KINDS, or a popular-author kind:3 sweep -- loses everything past the newest 100 on the first (and only) page drainGated fetched. On a dense set kindpag returned 100 events single-shot vs 238 paginated; nos.lol and damus (higher caps) matched at 246 and 127. drainGated never paginated -- it took one page and moved on -- so this bit every sweep and outbox query, not just the aggregator recovery. Truncated users became stragglers that the multi-round retry mostly (not always) recovered elsewhere, which is why it stayed hidden. Now any page that comes back at FULL_PAGE_THRESHOLD (100, the smallest cap observed) is treated as possibly-capped and its remainder is drained in the background with fetchAllPages `until` cursors, streamed to lateHarvest exactly like a parked slow relay (tracked by parkedInFlight so the round waits for it, gated by the limiter). The boundary second is re-fetched and de-duplicated by persist's crawl-wide seen-set, so nothing double-counts. Only dense pages pay the extra REQs; the common under-cap page is untouched.

Re-probing hop-8's failed relays fresh, outside the crawl, showed the two are not alike: relays that failed to ESTABLISH a connection (connect timed out, refused, unroutable, or the proxy couldn't tunnel the CONNECT) were 0/30 reachable — genuinely dead — while relays that hit a READ timeout were 12/18 (67%) reachable, alive but overloaded by the crawl's fan-out (user.kindpag.es among them). So classifyDrainFailure now returns HARD for connection-establishment failures (one strike drops them instead of burning two more dials on a dead host), while a read/generic timeout still returns null and stays on the patient, clear-on-success timeout-strike path so live-but-slow relays we need are not wrongly evicted. Mid-stream resets stay TRANSIENT. Adds DrainFailureTest, which the classifier previously had none of.

Collapse to a single DEAD verdict, dropped on the first strike, and carve out the only two connect failures that genuinely recover so they stay retryable (null): a READ timeout (relay answered the handshake, slow — 67% reachable fresh, kept on the clear-on-success authority-strike path) and an HTTP 429 rate-limit (alive, 4/4 reachable — retrying spaced by the limiter is how we get its data).

With 24 workers all waiting out their batches' slowest relay at once, progress dropped to 0 lists/sec in waves. Restructure to drain each relay independently and stream its result the instant it resolves — no per-batch join. A per-user counter (relaysLeft) tracks how many of a user's relays are still outstanding; the single-writer consumer finalizes a user (ingest, or count a failed outbox attempt) only when the last of its relays resolves, so correctness is unchanged. Concurrency is now a semaphore over relay-units rather than an implicit batches×fan-out product; drainConcurrency becomes "concurrent relay drains" (default 1024, ~the old 24-batch fan-out). A straggler the outbox model routes nowhere is finalized directly as a miss. Fast relays' lists are now ingested immediately instead of behind a batch's slowest relay, removing the 0/s stalls on slow-relay-heavy rounds.

The tiered trim logic keyed on the deprecated levels was therefore dead on any Android 14+ device. Rebuild the whole trim chain around the two levels still delivered: - UI_HIDDEN (every app switch): light trim — release image bitmaps, keep the CPU-heavy rich-text/Robohash caches warm so resuming is instant. - BACKGROUND (process on the LRU list, real reclaim pressure): aggressive — free every rebuildable cache, run the heavy LocalCache prune, release the ExoPlayer warm pool, trim feeds, and evict warm embedded tabs. Folds the old COMPLETE/MODERATE "free everything" behavior into BACKGROUND and removes all deprecated TRIM_MEMORY_* references across AppModules, MemoryTrimmingService, Amethyst, PlaybackService and AccountFeedContentStates.

Most fail slowly: a silently-dropping host has no RST to receive, so the WS connect just hangs to the 7s connectTimeout. First-strike eviction pays that once per host, but with ~3,000 dead hosts that's ~80s of connect-setup serialized through the dispatcher. Add a background reachability culler: a cheap raw TCP connect (one round trip, 2s timeout) over the learned relays COLD-TAIL FIRST, dropping the unreachable ones into deadHosts before the WS path pays its 7s. The key property is that a tight TCP timeout is safe where a tight WS timeout is not — a busy-but-alive relay accepts the SYN instantly at the kernel level and only stalls at the app layer, so the probe separates "unreachable" from "slow" and never false-kills the busy. It only ever marks dead and probes each authority once; a host the WS path already resolved (isDead) is skipped, and a live host passes the probe, so the WS verdict always wins. Injected as an optional Config.reachabilityProbe (JVM: java.net.Socket in the CLI; --no-probe disables); writeRelayFreq becomes concurrent so the culler can read it while routeByOutbox writes. Also: when there's no Tor transport (Config.torEnabled=false), isDead skips every .onion relay on sight — no socket, no wasted connect.

It reads every kind:10002 already in the local store, inverts them into a write-relay -> authors map (the outbox model), then runs one NIP-77 negentropy reconcile per write relay scoped to exactly the authors who publish there. Bidirectional by default; each group then settles deletions over the reconcile residual via quartz's negentropySettleDeletions, whose applyDown direction downloads the relay's covering kind:5 when an uploaded record was rejected because the author retracted it. When negentropy can't reconcile a relay (no NIP-77, an over-cap minimal window, a mid-sync disconnect), the group falls back to a full paged download (Context.drainAllPages) of the same authors+kinds so those records are still refreshed. Thin assembly only: reconcile, windowing, back-pressure, and deletion settle all live in the quartz relay-client accessories, mirroring SyncCommand; this only routes ids to Context.drain / drainAllPages / publish and inverts the relay list.

The signed From 4a686fc057a2318c3d4baf848e6da41f2d949983 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 9 Jul 2026 00:12:22 +0000 Subject: [PATCH 125/176] refactor(quartz): extract GrapeRankUpdater outbox-model WoT refresh utility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Moves the `amy graperank update` logic out of the CLI and into quartz as GrapeRankUpdater, alongside GrapeRankDataCrawler in experimental/graperank, so Android and any other quartz consumer can run the same refresh. Given an INostrClient + IEventStore it reads every kind:10002 in the store, inverts them into a write-relay -> authors map (the outbox model), then runs one NIP-77 negentropy reconcile per write relay scoped to its authors: bidirectional content sync into/from the store, deletion settle over the residual (applyDown downloads the relay's kind:5 when an uploaded record was rejected because the author retracted it), and a full paged-download fallback when a relay can't reconcile. Bounds and directions are a Config; per-relay and aggregate outcomes are returned as a Result. The CLI `graperank update` is now a thin wrapper: it parses flags, builds the Config, and renders GrapeRankUpdater.Result as text/JSON — no sync logic left in cli/ (all reconcile/window/back-pressure/deletion logic lives in quartz's relay-client accessories, which GrapeRankUpdater composes).

This is a set-difference the positive-only nostr Filter grammar can't express (there is no "NOT kind 10002"), so it lives as a dedicated IEventStore method rather than a query(Filter). The interface carries a correct default (collect authors-with-outbox, then stream events keeping the rest — O(events)); SQLiteEventStore overrides it with a single SELECT DISTINCT ... NOT EXISTS that seeks the outbox check on the (kind, pubkey, created_at) index. "Missing" is relative to what the store holds: an author whose only 10002 was deleted (NIP-09) or expired (NIP-40) is reported as missing again, since no row remains.

Given an INostrClient + IEventStore it syncs each (relay, filter) group: a bidirectional NIP-77 reconcile into/from the store (down/up), a deletion settle over the residual (applyDown downloads the relay's kind:5 when an uploaded record was rejected), and a paged-download fallback when a relay can't reconcile. sync() runs many groups with relays concurrent and each relay's own filters sequential (so one relay never exceeds its subscription budget). Directions and bounds are a Config; every group is best-effort and its outcome is a GroupResult. This is also the reusable engine `amy sync` open-codes today. GrapeRankUpdater now only owns the GrapeRank specifics: it reads kind:10002, inverts to write-relay -> authors (the outbox model), fans that into one filter per (relay, author chunk), hands the set to NegentropyStoreSync, and folds the per-group results back up per relay. Its public Config/Result and the CLI wrapper are unchanged.

Reconcile now uses store.snapshotIdsForNegentropy (id + created_at only, ~40 B/entry) and the uploader fetches only the residual haves by id. Peak memory drops from O(all local matches) to O(residual) — matters when a relay hosts a large set. - Bug: sync() promised best-effort ("one bad relay can't abort the set") but syncGroup only caught NegentropySyncException, so any other failure (store I/O, an unexpected throw) escaped async and cancelled every other relay via awaitAll. Each group now runs under a guard that records the failure instead. - Bug: the page-fallback catch (Exception) swallowed CancellationException, breaking cooperative cancellation.

Both the SQLite path and the generic default now exclude kind 1059 from the "authors" set. - Performance: replaced the DISTINCT + correlated NOT EXISTS scan with an index-only EXCEPT (all authors minus 10002 owners). Both sides ride the unconditional query_by_kind_pubkey_created covering index — so it does NOT depend on the optional pubkey-alone index — and measured ~3x faster (44ms vs 137ms at 152k events / 20k authors); the gap widens with author count, since the old form paid one seek per distinct author. A loose-index skip-scan was rejected: it needs the pubkey-alone index and degrades to a full scan per author without it. Also: corrected the KDocs (the old text implied an efficient index-only distinct that wasn't guaranteed), added a giftwrap-exclusion test, and added FsAuthorsMissingOutboxTest — the only coverage of the IEventStore DEFAULT implementation, which EventStore always overrides.

Add an immutable view alongside: RelayAuthSnapshot (phase + lastAuthSuccessAt). RelayAuthStatus.snapshot() derives it from the LRU. RelayAuthenticator publishes a PersistentMap via authStateFlow on every mutation (connect, disconnect, AUTH-submitted, AUTH-OK, AUTH-fail). PersistentMap gives O(log32 n) updates and a fresh identity per put, so both StateFlow equality and Compose strong-skipping work. This is the substrate for downstream consumers — the AUTH approval banner, the retry-queue wake on authCompleted, the indexer-fan-out gate — none of which are wired yet.

For desktop there is no AUTH wiring at all — challenges are ignored, so AUTH-walled relays silently drop DMs. Both behaviours fail the security review: unconditional signing lets any relay the user reads (or any malicious relay they touch) extract an identity-key signature with timestamp, and signing across all accounts links them under one relay observer. This commit adds the substrate for a tiered classifier — wire-up will follow with the desktop AuthCoordinator (P2.5) and SQLite-backed persistence (P2.4).

Backs the `auth_approvals` use case from the plan using java.util.prefs.Preferences instead of the originally proposed sibling outbox.db SQLite table. Trade-off rationale: the AUTH approval set per account is small (typically < 50 relays for any user) and the read pattern is bounded (one lookup per relay per session, easily cached in memory by the policy layer). java.util.prefs is already in use elsewhere on desktop (SearchHistoryStore, DesktopPreferences) and adds zero new dependencies or schema migrations. The retry_queue table from the same outbox.db proposal needs the higher-throughput characteristics SQLite gives us; it remains scoped to P3 (send visibility), which can introduce a proper sibling DB at that point. Per-account scoping by Preferences node — logout/account-delete calls clear() which removeNode()s the subtree. ONCE scope is never written to disk, enforced explicitly here in addition to the interface contract. Not yet wired into a DesktopAuthCoordinator (today desktop has NO AUTH wiring at all). That wiring lands in P2.5 alongside the banner UI. --- .../auth/PreferencesAuthApprovalStore.kt | 81 +++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/auth/PreferencesAuthApprovalStore.kt diff --git a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/auth/PreferencesAuthApprovalStore.kt b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/auth/PreferencesAuthApprovalStore.kt new file mode 100644 index 0000000000..ff47f1d38d --- /dev/null +++ b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/auth/PreferencesAuthApprovalStore.kt @@ -0,0 +1,81 @@ +/* + * Copyright (c) 2025 Vitor Pamplona + * + * Permission is hereby granted, free of charge, to any person obtaining a copy of + * this software and associated documentation files (the "Software"), to deal in + * the Software without restriction, including without limitation the rights to use, + * copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the + * Software, and to permit persons to whom the Software is furnished to do so, + * subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS + * FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Other clients the recipient runs (or relays acting as inbox routers) can then locate the wrap without performing their own kind:10050 lookup — handy when the recipient is multi-device and the second device's 10050 cache is cold. GiftWrapEvent.create gains an optional `recipientRelayHint: NormalizedRelayUrl?` parameter that flows into PTag.assemble (which already accepts a relay hint). NIP17Factory.createWraps and the four public createMessageNIP17 / createEncryptedFileNIP17 / createReactionWithinGroup entry points gain a matching `recipientRelayHints: (HexKey) -> NormalizedRelayUrl?` lambda so multi-recipient sends can pass per-recipient hints in one shot. All new parameters default to null / { null }, so every existing caller compiles unchanged and still emits the historical two-element ["p", recipientPubKey] shape. Callers that resolve kind:10050 via the (forthcoming) DmInboxRelayResolver can wire the result through to populate the hint. While here, document the existing — but undocumented — invariant that shared rumor created_at falls out naturally because the rumor is signed once before the per-recipient mapNotNullAsync loop. This is what anchors cross-recipient reaction/receipt dedupe. --- .../quartz/nip17Dm/NIP17Factory.kt | 28 ++++++++++++++++--- .../nip59Giftwrap/wraps/GiftWrapEvent.kt | 16 +++++++++-- 2 files changed, 38 insertions(+), 6 deletions(-) diff --git a/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip17Dm/NIP17Factory.kt b/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip17Dm/NIP17Factory.kt index 62ef1da15d..9a848a319b 100644 --- a/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip17Dm/NIP17Factory.kt +++ b/quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/nip17Dm/NIP17Factory.kt @@ -23,6 +23,7 @@ package com.vitorpamplona.quartz.nip17Dm import com.vitorpamplona.quartz.nip01Core.core.Event import com.vitorpamplona.quartz.nip01Core.core.HexKey import com.vitorpamplona.quartz.nip01Core.hints.EventHintBundle +import com.vitorpamplona.quartz.nip01Core.relay.normalizer.NormalizedRelayUrl import com.vitorpamplona.quartz.nip01Core.signers.EventTemplate import com.vitorpamplona.quartz.nip01Core.signers.NostrSigner import com.vitorpamplona.quartz.nip01Core.tags.people.taggedUserIds @@ -43,10 +44,24 @@ class NIP17Factory { val wraps: List, ) + /** + * Build one NIP-59 gift wrap per recipient. + * + * The rumor (kind 14) `created_at` is implicitly shared across all wraps + * because [event] is signed once by the caller before the per-recipient + * loop runs — every seal encodes the same rumor `id`.

Same class of bug as the relay- power-tools work explicitly closed for the relay picker on 2026-04-20 ("block DM fallback to all relays — metadata leak"). Replace the fallback with strict resolution: if the recipient has no kind:10050 in the cache, return an empty target set. DmSendTracker already handles total relay count == 0 with a "No relays available" failure state, so the user gets a visible error instead of a silent leak. Indexer fan-out + a UI dialog for the missing-10050 case is the permanent fix, scoped to Phase 4 (DmInboxRelayResolver). This commit is the conservative pre-Phase-4 plug — better to fail visibly than leak silently. NIP-04 send is unchanged: that path is pre-NIP-17, the encrypted content sits next to other public events on the sender's outbox by design. --- .../amethyst/desktop/model/DesktopIAccount.kt | 68 +++++++++---------- 1 file changed, 32 insertions(+), 36 deletions(-) diff --git a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/model/DesktopIAccount.kt b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/model/DesktopIAccount.kt index 20fccefa62..672c8bb6b4 100644 --- a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/model/DesktopIAccount.kt +++ b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/model/DesktopIAccount.kt @@ -35,6 +35,8 @@ import com.vitorpamplona.amethyst.desktop.account.AccountState import com.vitorpamplona.amethyst.desktop.cache.DesktopLocalCache import com.vitorpamplona.amethyst.desktop.network.RelayConnectionManager import com.vitorpamplona.amethyst.desktop.ui.chats.DmSendTracker +import com.vitorpamplona.quartz.nip01Core.core.HexKey +import com.vitorpamplona.quartz.nip01Core.relay.normalizer.NormalizedRelayUrl import com.vitorpamplona.quartz.nip01Core.signers.EventTemplate import com.vitorpamplona.quartz.nip01Core.signers.NostrSigner import com.vitorpamplona.quartz.nip02FollowList.ContactListEvent @@ -197,18 +199,7 @@ class DesktopIAccount( val batch = result.wraps.map { wrap -> val recipientKey = wrap.recipientPubKey() - val targetRelays = - if (recipientKey != null) { - val dmRelays = - localCache - .getOrCreateUser(recipientKey) - .dmInboxRelays() - ?.toSet() - dmRelays?.ifEmpty { null } - ?: relayManager.connectedRelays.value - } else { - relayManager.connectedRelays.value - } + val targetRelays = resolveDmInboxRelaysStrict(recipientKey) wrap to targetRelays } @@ -228,18 +219,7 @@ class DesktopIAccount( val batch = result.wraps.map { wrap -> val recipientKey = wrap.recipientPubKey() - val targetRelays = - if (recipientKey != null) { - val dmRelays = - localCache - .getOrCreateUser(recipientKey) - .dmInboxRelays() - ?.toSet() - dmRelays?.ifEmpty { null } - ?: relayManager.connectedRelays.value - } else { - relayManager.connectedRelays.value - } + val targetRelays = resolveDmInboxRelaysStrict(recipientKey) wrap to targetRelays } @@ -250,24 +230,40 @@ class DesktopIAccount( val batch = wraps.map { wrap -> val recipientKey = wrap.recipientPubKey() - val targetRelays = - if (recipientKey != null) { - val dmRelays = - localCache - .getOrCreateUser(recipientKey) - .dmInboxRelays() - ?.toSet() - dmRelays?.ifEmpty { null } - ?: relayManager.connectedRelays.value - } else { - relayManager.connectedRelays.value - } + val targetRelays = resolveDmInboxRelaysStrict(recipientKey) wrap to targetRelays } scope.launch { dmSendTracker.sendBatch(batch) } } + /** + * NIP-17 inbox-relay resolution, strict variant — no fallback to the + * user's connected relays. + * + * Per NIP-17 §Publishing, a gift wrap MUST only land on relays advertised + * in the recipient's kind:10050.

Each seal needs nip44_encrypt + sign — for a NIP-46 (bunker) signer that means two round-trips per recipient. A 5-recipient group send launches 10 concurrent in-flight requests against the bunker socket, and nsec.app / Amber / Keychat typically serialize past ~10 in-flight, so some requests queue past the 65s timeout and silently fail. Cap at 4 concurrent when signer is NostrSignerRemote. Local signers (NostrSignerInternal, NostrSignerSync) bypass the semaphore and stay fully parallel — no overhead, no behaviour change for nsec users. The real fix is the batched nip44_get_conversation_keys NIP-46 RPC (separate spec PR + plan) which collapses N×2 round-trips into ~2.

This commit closes the gap, but does it the security-conscious way using the AuthApprovalPolicy substrate from earlier commits. DesktopAuthCoordinator binds to AccountState transitions in Main.kt and per logged-in account: - constructs a PreferencesAuthApprovalStore scoped by pubkey - constructs an AuthApprovalPolicy with self-approved relays sourced from the active account's NIP-17 DM-inbox (kind:10050) cache - constructs a RelayAuthenticator whose signWithAllLoggedInUsers lambda routes every AUTH challenge through the policy Tier 1 (own DM-inbox + persisted ALWAYS) signs automatically. Tier 2 challenges hand back a CompletableDeferred surfaced on authCoordinator.pendingApprovals. Until the inline banner UI lands (P2.5 follow-up), tier-2 pending stays unresolved — which means tier-2 relays don't get an AUTH response, same outcome as the pre-this-commit world. The improvement here is tier-1: own DM inbox relays now AUTH automatically without any prompt. Lifecycle: onLogin attaches the authenticator; onLogout and account- switch tear it down and complete any pending deferreds with BLOCKED so suspended signers don't dangle. Self-approved relays are deliberately scoped to kind:10050 (DM inbox) only, NOT NIP-65 write/read relays.

Each row shows the relay's display URL plus message-count when multiple challenges from the same relay have coalesced. The composable itself is in commons so Android picks it up free when its AccountAuthApprovals VM wire-up lands — only the Main.kt-level wiring (where to mount the banner in the layout) is platform-specific.

LocalCache hit — if the caller already saw the user's kind:10050 via the regular feed pipeline, skip I/O entirely. 2. In-memory LRU cache — TTL 1h, 100 entries; avoids re-querying indexers when opening several conversations in sequence. 3. Indexer fan-out — RecipientRelayFetcher against a curated set (DefaultDmIndexerRelays: relay.nos.social, relay.damus.io, nos.lol, relay.nostr.band, purplerelay.com — purplepag.es deliberately excluded for poor kind:10050 coverage). Strictness vs. the existing User.dmInboxRelays(): - filters to kind:10050 ONLY; NEVER falls back to NIP-65 read marker (kind:10002). User.dmInboxRelays() silently substitutes that, which is the same metadata-leak class fixed by 5293dae65. - empty list = canonical "unreachable" signal; caller refuses to publish (DesktopIAccount.resolveDmInboxRelaysStrict already does this). Security: the NostrClient passed in MUST be a dedicated unauthenticated instance — no RelayAuthenticator attached. An authenticated indexer fan-out (the current state with the primary client) would extract identity-key signatures during the kind:10050 probe, escalating "indexer learns we want to DM pubkey X" into "indexer learns user U wants to DM pubkey X". KDoc warning is explicit; Phase 4 follow-up creates the unauth client in Main.kt and injects it.

DesktopIAccount.resolveDmInboxRelaysStrict now uses the resolver injected from Main.kt instead of the LocalCache-only fast path. Three-layer lookup at every call: 1. LocalCache hit (kind:10050 already observed via feed pipeline) 2. Resolver's 1h LRU cache 3. Indexer fan-out via the dedicated unauthenticated NostrClient The unauthenticated NostrClient is constructed in App() alongside relayManager and connects on creation; DisposableEffect disconnects on the App-level dispose. Critically NO RelayAuthenticator is attached to this client — only the primary relayManager.client has one (via DesktopAuthCoordinator). This closes security review F-01: indexer queries no longer extract identity-key signatures during kind:10050 probes against curated indexers. resolveDmInboxRelaysStrict is converted from sync to suspend; the three send paths (sendNip17PrivateMessage, sendNip17EncryptedFile, sendGiftWraps) already run in suspend context inside DmSendTracker batches, so the conversion is local. Resolver is plumbed through MainContent as a new parameter rather than a CompositionLocal — explicit threading matches the existing pattern for accountRelays and relayManager. The legacy LocalCache-only fallback inside resolveDmInboxRelaysStrict is preserved for the constructor-default case (tests, CLI). When dmInboxResolver is null, behaviour matches the pre-this-commit strict-fix from 5293dae65. --- .../vitorpamplona/amethyst/desktop/Main.kt | 40 ++++++++++++++++++- .../amethyst/desktop/model/DesktopIAccount.kt | 34 +++++++++++----- 2 files changed, 61 insertions(+), 13 deletions(-) diff --git a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/Main.kt b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/Main.kt index 0f10968872..0c1f451573 100644 --- a/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/Main.kt +++ b/desktopApp/src/jvmMain/kotlin/com/vitorpamplona/amethyst/desktop/Main.kt @@ -71,6 +71,7 @@ import androidx.compose.ui.window.Window import androidx.compose.ui.window.WindowPosition import androidx.compose.ui.window.application import androidx.compose.ui.window.rememberWindowState +import com.vitorpamplona.amethyst.commons.defaults.DefaultDmIndexerRelays import com.vitorpamplona.amethyst.commons.icons.symbols.Icon import com.vitorpamplona.amethyst.commons.icons.symbols.MaterialSymbols import com.vitorpamplona.amethyst.commons.icons.symbols.ProvideMaterialSymbols @@ -78,6 +79,7 @@ import com.vitorpamplona.amethyst.commons.moderation.LocalHashtagSpamSettings import com.vitorpamplona.amethyst.commons.moderation.LocalSpamExemptKeys import com.vitorpamplona.amethyst.commons.moderation.PreferencesHashtagSpamSettings import com.vitorpamplona.amethyst.commons.relayClient.auth.AuthApprovalBanner +import com.vitorpamplona.amethyst.commons.relayClient.nip17Dm.DmInboxRelayResolver import com.vitorpamplona.amethyst.commons.relayClient.nip17Dm.unwrapAndUnsealOrNull import com.vitorpamplona.amethyst.commons.wot.LocalWoTReady import com.vitorpamplona.amethyst.commons.wot.LocalWoTService @@ -126,9 +128,12 @@ import com.vitorpamplona.amethyst.desktop.ui.relay.RelayStatusCard import com.vitorpamplona.amethyst.desktop.ui.settings.ImageCompressionSettings import com.vitorpamplona.amethyst.desktop.ui.settings.MediaServerSettings import com.vitorpamplona.amethyst.desktop.ui.settings.NamecoinSettingsSection +import com.vitorpamplona.quartz.nip01Core.relay.client.NostrClient import com.vitorpamplona.quartz.nip01Core.relay.client.reqs.SubscriptionListener import com.vitorpamplona.quartz.nip01Core.relay.filters.Filter import com.vitorpamplona.quartz.nip01Core.relay.normalizer.NormalizedRelayUrl +import com.vitorpamplona.quartz.nip01Core.relay.normalizer.RelayUrlNormalizer +import com.vitorpamplona.quartz.nip01Core.relay.sockets.okhttp.BasicOkHttpWebSocket import com.vitorpamplona.quartz.nip17Dm.base.ChatroomKeyable import com.vitorpamplona.quartz.nip17Dm.settings.ChatMessageRelayListEvent import com.vitorpamplona.quartz.nip37Drafts.DraftWrapEvent @@ -924,6 +929,35 @@ private fun AppInner( } val nip11Fetcher = remember { Nip11Fetcher() } + // Dedicated unauthenticated NostrClient for kind:10050 lookups against + // curated indexer relays.

Backwards compatible: - Pending stays a data object — existing callers' `is Pending` checks unaffected. - New helper `isPending()` returns true for both Pending and Progress; SigningState.execute uses it so a second execute() during Progress returns null (matching the old single-flight semantics). - SigningAwareButton renders both Pending and Progress as a spinner; callers wanting the counter must read the state directly. - SigningStatusBar adds a Progress branch that shows "
