From 94aa00e4d766bc6bb2f814816f43fd74358b63e9 Mon Sep 17 00:00:00 2001 From: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 Date: Fri, 31 Jul 2026 16:04:34 -0400 Subject: [PATCH 01/19] feat(read-state): add override layer to ReadStateManager (slice 2) Implements the manual-unread override manager layer on top of the slice-1 wire protocol: - Full-state fetch without a since filter; isLoadComplete gate blocks publish, deleteExtraSlots, markChannelUnread, and markChannelRead until a sub-limit response confirms no truncation. - Override register merge in mergeEvents (componentwise max via mergeReadStateEventsStructured). - Override wire entries (ov_s/c/b) included in currentContexts and splitContextsIntoSlots output; ov_* entries pinned to slot 0 in splitContextsIntoBudgetedSlots and exempt from trimContextsToBudget eviction. - Public APIs: markChannelUnread, markChannelRead, getOverrideLiveness. - Tests: override pinning in non-primary slots is rejected, full-page fetch blocks gated ops, budget and uint32 overflow refuse cleanly.

Mark-as-read clears the override (C bump) if an active override exists. Both operations surface user-visible toasts on failure: budget exhaustion, counter overflow, or incomplete load. forcedUnreadStore becomes a local-device cache of the synced override layer rather than the sole source of truth; its doc comment is updated accordingly. Adds readStateOverride.ts with the applyOverrideUnread / applyOverrideRead / persistForcedUnread helper seam, and extends useReadState to expose the three manager override callbacks (markChannelUnread / markChannelRead / getOverrideLiveness) used by useUnreadChannels. Includes nip-rs-unread-ui.test.mjs with 22 behaviour-focused tests covering all refusal paths and the local-cache contract.

Completeness comes from the terminal proof (empty continuation after all bands discharged), never from requested-limit arithmetic. fetchAndMerge is now callable repeatedly; a second call can clear isLoadComplete=false. CRITICAL-2 (live override merge): Route handleIncomingEvent through the shared ingest() path instead of raw blob.contexts iteration. ingest() already componentwise-merges (S,C,B) registers via mergeReadStateEventsStructured. CRITICAL-3 (read-before-write): fetchOwnBlobBeforePublish returns a boolean; publish() aborts when it returns false. Enforced at the start of every publish before any canonicalization or coordinate deletion. IMPORTANT (escaping/grouping): splitContextsIntoBudgetedSlots applies unescapeFrontierKey before testing group identity so esc:ov_s:evil is correctly colocated with ov_*:ov_s:evil in the primary slot. IMPORTANT (budget trial): currentContextsWithOverride already correctly trials the full contexts snapshot; no change needed to the planner shape since the committed test was a false assertion — the new test exercises both adversarial directions correctly. IMPORTANT (durability): Override registers are now persisted atomically with frontier state via readStateStorage (new localOverrideRegistersKey key, readOverrideRegisters/writeStoredReadState extended). hydrateFromLocalStorage componentwise-merges stored registers before relay work.

CRITICAL 2: Explicit mark-read as one outcome-bearing transition. - applyOverrideRead now returns OverrideReadOutcome instead of void. Order: frontier advance → C-bump → re-read liveness. Clears local presentation only when liveness is confirmed inactive. null ≠ inactive: pre-init returns overrideStillActive (fail-closed). already_inactive race: silent success (overrideCleared). - markChannelRead and markAllChannelsRead gate the local cache delete on outcome === "overrideCleared". IMPORTANT 1: No local mutation on refusal. - useChannelUnreadState.handleMarkUnread now calls markChannelUnread first and does not add to forcedUnreadRef; the session-level timeline overlay is not set before or on refusal. IMPORTANT 2: Tests exercise production code. - Delete handwritten simulations and assert.ok(true) placeholder. - Import and invoke applyOverrideUnread, applyOverrideRead, persistForcedUnread, overrideErrorMessage directly with injected deps. - Witnesses: null-liveness pre-init, inactive-without-C-bump, active-success, active-uint32_overflow refusal, active-load_incomplete refusal, already_inactive race, persistForcedUnread refresh-on-existing-entry. - Test count: 19 → 27. MINOR 1: OverrideAPIs functions now required (no optional-chain fail-open). MINOR 2: Remove duplicate MarkResult/OverrideLiveness from forcedUnreadStore; move overrideErrorMessage/toast policy to readStateOverride.ts. Also fix persistForcedUnread to refresh existing entries (re-mark after a dead override uses the current frontier as baseline).

Override state is exempt from finite- horizon fetching. Authoritative sources are now (a) readStoredReadState overrideRegisters (persisted full-state projection) and (b) coordinate- deduped fetched events merged via max() per field. The stale-cache fallback that produced false positives and false negatives on old/tombstoned registers is removed; the observer test is updated to match the new authoritative model. IMPORTANT: restore divider suppression — markChannelUnread returns boolean; applyMarkUnreadDividerOverlay (extracted pure helper in useChannelUnreadState) gates forcedUnreadRef.add() on success. handleMarkUnread calls this helper instead of the old unconditional/void path. AppShellContext default updated. IMPORTANT: explicit read always attempts C-bump (NIP-RS:537-539) — applyOverrideRead step logic reordered: !isReadStateReady fails closed; liveness===null (ready, no register) = known absence, cleared; register exists → always call markChannelRead regardless of active/inactive, then inspect resulting liveness. isReadStateReady in OverrideAPIs distinguishes manager-unavailable (fail closed) from known-no-register (cleared). IMPORTANT: hook witnesses drive production code — applyOverrideRead tests replaced with seven new tests using makeApis() reflecting the new semantics; two new applyMarkUnreadDividerOverlay tests exercise the extracted production transition (success adds to overlay, refusal does not).

Timeout never counts as establishment. - Epoch-zero: terminate complete directly after pinned-window discharged at T=0; no until:0 continuation issued (would re-fetch same event on conforming relay). Residual 2 (I2 — storage commit point): - v2 override write is the action commit point; ancillary frontier/cache writes are best-effort and do not fail the action. persistLocalState() returns false only when v2 write fails; caller rolls back all state including slot IDs. - restoreExtraSlotIds() skips saveExtraSlotIds when IDs unchanged — prevents spurious extra-slot-ids key creation on a no-slot-change rollback. Residual 3 (I3 — real-primitive tests): - Test 17/18: createFencedSubscription establishment-timeout lapses fence and never counts as establishment. - Test 19: no-EOSE relay with timeout produces incomplete load (Thufir witness). - Test 20: early-write-fails/v2-succeeds — action succeeds, restart agrees. - Test 21: v2-write-fails — storage_failed, extraSlotIds unchanged in memory and persisted extra-slot-ids key unchanged. - Test 22: fetchOwnBlobBeforePublish foreign client_id rotates slot and updates maxFetchedCreatedAt via the parsed-record path. - Epoch-zero test (2g) uses inclusive-filter-conforming fixture.

Timer race (relayClientShared.ts): install the establishment timer and wrapped resolver BEFORE sendReq() so EOSE delivered during the send promise correctly cancels the timer and never lapses an established fence. Guard via alreadyEstablished boolean. Witnesses: Test 14b (EOSE-during-send stays unlapsed past timeout window). 2. Hydration publishability (readStateManager.ts): v2 override entries are inherently publishable — the v2 record is the action commit point, so any context in it was committed regardless of ancillary key writes. Add every v2/migrated context to publishableContextIds in hydrateFromLocalStorage(). Witness (Test 20): reconstructed manager has publishableContextIds containing the committed context and currentContexts() non-null with the register/frontier. 3. v2-failure durable leakage (readStateStorage.ts + readStateManager.ts): - writeStoredReadState() early-returns on v2 failure before any ancillary write — 'v2 false => nothing durable anywhere'. - restoreExtraSlotIds() removes the key when prev was empty (absent -> absent), not write [] on rollback. Witness (Test 21): 700 frontier contexts force split planning; assert raw storage value is storage-identical after failed v2 write including absent-vs-present.
