From 741c377f805b90730bd7accf85758054d7390293 Mon Sep 17 00:00:00 2001 From: nrobi144 Date: Thu, 2 Jul 2026 18:03:12 +0300 Subject: [PATCH 01/46] 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 06/46] 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.

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.

Per-key isolation is a `SnapshotStateMap` property, not a `withMutableSnapshot` property; the `withMutableSnapshot` on *every* op just batches writes.

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. Both + `handleKind3` and every future op must early-return on `disabled`. +- In the outbox driver's entrypoint (formerly `Main.kt:1561`), consult + `WoTService.isDisabled` (new StateFlow) or `follows.size <= + WoTService.MAX_FOLLOWS` before dispatching Phase 1.

Add an internal `AutoCloseable` implement so callers can lean on +`use { }`. + +**Fix 4 — Correct the misleading comments.** Rewrite `WoTService` KDoc to say: + +> Scores are exposed via a Compose-observable `SnapshotStateMap`. Consumers +> that read a *specific key* (`scores[pubkey]`) recompose only when that key +> changes — this is `SnapshotStateMap`'s per-key observation. Consumers that +> iterate the map or read its size will recompose on any mutation. +> +> Ops are serialized through a single-writer `Channel`. Coalescing writes +> inside `Snapshot.withMutableSnapshot { }` batches state commits so a +> multi-key op emits a single Compose invalidation instead of one per key. + +No behaviour change; the comment is the fix. + +**Fix 5 — `queuedKind3Pubkeys` retryable.** Convert the current mark-on-send +set into mark-on-EOSE: +- Track `inFlight: MutableSet` for de-duplication during a single call. +- On successful EOSE (or per-relay EOSE), move pubkeys into `succeeded` + (unchanged behaviour: skip future REQs). +- On global timeout with zero events for a pubkey, **do not** promote to + `succeeded`; keep them retryable on the next `loadKind3Batched` / + `loadKind3ViaOutbox` call. +- Cheap: same `Set` mechanics, just gated by outcome instead of intent. + +**Fix 6 — Synchronise `eoseReceived`.** Two options; pick (b): +- (a) Wrap in `Mutex` / `synchronized` — `synchronized` needs a JVM-only + path or an `expect/actual`. +- (b) **Use a single-writer coroutine**: replace the `MutableSet` + + `CompletableDeferred` handshake with a `Channel( + capacity = Channel.UNLIMITED)` + a launched consumer that increments a + local counter and completes the deferred when it hits `indexRelays.size`. + Same shape, zero shared mutable state across dispatchers. KMP-clean. + +Apply the same fix to both `loadKind3Batched` and `loadMetadataBatched` +because the pattern is duplicated. + +### Damus sweep + +Grep of the current branch found `relay.damus.io` only in test fixtures +(`FeedDefinitionSerializerTest`, `TorRelayEvaluationTest`, `RichTextParserTest`, +`ZapSplitResolverTest`).

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. Ships 3 new PrivacyLockStateTest cases: independent per-scope state, shared failed-attempt counter, and the password-clear cascade.

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.

From dddeae74b657622fa49c44066ca63c84fd2f8ab6 Mon Sep 17 00:00:00 2001 From: nrobi144 Date: Tue, 7 Jul 2026 13:26:38 +0300 Subject: [PATCH 11/46] =?UTF-8?q?feat(wot):=20OutboxDispatcher=20=E2=80=94?= =?UTF-8?q?=20fetch=20kind=200/3=20via=20each=20author's=20outbox=20relays?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reviewer Vitor (PR #3483): stop blasting kind 0/3 REQs at a static index relay list. 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).

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.

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.

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).

Record in the docstring what the phase breakdown proved: the settle's extra time over a bare reconcile is O(K) relay-ingest of the K residual deletions, dominated by one-time JVM/JIT warmup of the publish path (consecutive K-note batches fell ~3100->570ms), not the deletion algorithm and not O(N).

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.

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 44/46] 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).

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 new catch sites rethrow it.
