From 94aa00e4d766bc6bb2f814816f43fd74358b63e9 Mon Sep 17 00:00:00 2001 From: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 Date: Fri, 31 Jul 2026 16:04:34 -0400 Subject: [PATCH 01/10] 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.

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.

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.

After a v2-success/ancillary-failure commit, the stale ancillary value suppressed the authoritative v2 frontier — the register appeared active when it should have been inactive (F > B). Fix: apply effectiveState[ctx] = max(existing ?? 0, e.f) for every v2/migrated override entry, unconditionally replacing the stale ancillary value with the authoritative committed frontier when it is higher. Test 22b: hydrateFromLocalStorage_staleAncillaryFrontier_v2FrontierWins — Thufir's exact policy-edge witness. Seeds stale ancillary frontier=50 and v2 {s:5,c:0,b:100,f:101}. Asserts effectiveState=101 after hydration, register inactive (101>B=100), and currentContexts() serializes tombstone (ov_c: only, no ov_s:).
