glm-5.3-flash 23cf0e7046 chore(deps): normalize engines' dev-dep tokio features (review 004 item 16) ...

All three engines' [dev-dependencies] tokio now carry the same feature
set: rt-multi-thread + macros + time + test-util (previously sqlite had
rt-multi-thread+macros+time, pg test-util only, mem rt+macros).
Dev-dep metadata only; each engine's tests verified green plus the
workspace build/clippy/fmt gates.

core-pin-offset-initial-value.md

core: verify and pin the receiver's pre-yield offset() value (review 004 item 12, core-pin-offset-initial-value) — the three engines verified equal live, so the doc-pin branch applies: offset() reads 0 before any yield on every receiver — fresh consumer, stored positive checkpoint, stored negative seed (ADR-023 §2's totality arm, the one a checkpoint-seeded realization would surface on) — the no-yield sentinel, never the stored checkpoint: the checkpoint gates the feed's attach-read start while the receiver's offset tracks the last-yielded event only, composing with the pinned pre-yield save_offset() no-op; the attach read's prefetches sit unobserved and the first recv/try_recv observation is the first move (then the post-yield value, receiver_close_and_save_arms' pin). Verified by code read first (all three offset() bodies are self.position, all three constructors seed position: 0 unconditionally — mem stream.rs:353, sqlite :399, pg :620) then live: new suite row receiver_offset_pre_yield_is_zero (alkstore-contract-suite, stamped ADR-008 §8 + the core-contract.md pin, four arms incl. the first-observation composition leg) green on all three columns, pg against the harness server (parked pglo-poc :15432); pinned in three places: core-contract.md streams/subscribe row (dated 2026-10-11 annotation) + a verification-backlog bullet recording the verified pin, the core trait doc on offset() (core's doc comments are contract text), and the suite row itself — ADR-008 §8's shape comment deliberately left untouched (doc-only verification takes no ADR amendment, noted in the task); no engine code changed, no divergence to raise; gates green: workspace build/tests server-less, full pg column vs harness (135+26+9), clippy -D warnings, fmt --check, doc gate zero warnings, fuzz corpus replay 6/6, wasm32 mem check, taskgraph validate (96); task -> completed

mem-engine-foundations.md

mem-engine-foundations — the mem engine's foundations land (alkstore-mem, wave 6 task 1 of the ADR-024 chain): fourth workspace member with the manifest surface ADR-024 §1 pins — alkstore versioned path pin (ADR-017 §4.1) plus tokio restricted to the wasm-supported subset (sync + time; dev-deps rt/macros for the current-thread-flavor tests), no driver deps, no parking_lot (the description's prose named it, but the ADR + acceptance criterion pin the manifest tighter — short-held internal guards are std::sync::Mutex behind a state::Guard trait that folds poisoning away structurally, guards never held across awaits or user code, tokio mpsc the cross-await primitive). Five modules re-exported from lib.rs whose crate docs carry the ADR-016 posture statement (honest-ephemeral, full contract v1, wasm32-compile-clean identity, architecture sketch with the wave-6 construction line). MemStore::new() is the engine-native isolated constructor (ADR-024 §4's documented open-prose exception): fresh guarded state core (state.rs — empty named per-mechanism sections QueueState/StreamState/LockState/ScheduleState, shapes owned by the mechanism tasks), fresh wake bus, fresh clock per open; teardown is drop driving WakeBus::close() — no explicit close form. Wake substrate (wakes.rs): WakeBus::attach → WakeFeed (one unbounded mpsc feed per subscriber, detach-on-drop, attach under the registry guard so attach-after-commit no-replay is structural), fire_commit_wakes(channels) as the commit-ordered wake source's entry point (guard makes watermark bump + per-channel fanout one operation — per-subscriber FIFO by commit order, never coalesced), close empties senders so engine drop disconnects every feed; commit_watermark is a cfg(test) ordering observable only. Clock (clock.rs): one accessor Clock::unix_now over SystemTime, freeze/advance/unfreeze as the cfg(test) deterministic-seam; MemStore clock/wakes cfg(test) accessors. Validation (validation.rs) carries no new rule — pin module only (empty/whitespace InvalidName, prefix ReservedName, RESERVED_LISTENER_RECONNECTED rejected though unused here); mechanisms route core's validate_shared_name/local_name directly. Targeted allow(dead_code) on not-yet-wired scaffold surfaces so clippy -D warnings stays green pre-consumer (mechanism tasks own exhausting the allows); tokio time pinned unexercised (lock-TTL/scheduler consumers arrive with their tasks). Unit pins: 17 mem tests — two-instances-share-nothing (Arc pointer identity + behavioral: frozen clock isolation, cross-instance wake silence), state section independence/relock, wake routing (channel-scoped + foreign silence, per-notify never coalesced, watermark-ordered FIFO, no-replay, close disconnects all + post-close inert, dropped feed detaches), engine-drop closes feeds, clock determinism, validation pin row. Task file: status completed, Notes (decisions of record: parking_lot rejection, empty sections, substrate API shape, no-close, scaffold allow posture, unexercised time feature) + Summary filled. Verified: cargo build; workspace cargo test green (pg 124/25/9, sqlite 191/25, core 25, suite 3, mem 17); clippy --all-targets -D warnings clean; cargo fmt --check clean; cargo check --target wasm32-unknown-unknown -p alkstore-mem clean — the wave-6 wasm gate starts green from this task onward

mem-engine-integration.md

mem engine integration — the suite's third column lands, born pinned: StoreFactory implemented for the mem engine (alkstore-mem/tests/contract_suite.rs — a fresh MemStore::new() per open, teardown = drop, unit-struct factory with no external backing) and all 25 rows wired under the current-thread flavor (every test explicitly flavor = "current_thread" — the no-spawn_blocking posture proven by the flavor the column runs under, grep re-verified clean): the 24 engine-shared mechanism rows + mem's new PayloadTooLarge non-occurrence arm row (payload_too_large_never_produced_on_mem — properties.rs, stamped ADR-016 §5 + ADR-024 §3, just-past-2-MiB payload, exported from the suite lib; the SQLite/pg rows untouched — a suite-side class-4 addition, recorded in the task Notes). Column green first run (13 s), zero red rows — no mem defects, no row wobbles, no class-1 escalation owed. Full-surface wiring + crate posture/wasm-identity docs verified as landed by the seam/foundations tasks — zero production code changed. engine-mem.md frontmatter: draft → implementation-complete (stable flip stays with the review gate). Task file: status completed, 6 acceptance boxes ticked, Notes (incl. the wasm on-target scope-out's named collapse condition: a wasm-bindgen-test adapter crate, deliberately not an OQ) + Summary filled.

mem-engine-scheduler-outbox.md

mem engine scheduler/outbox — coverage reconciliation against the seam task's foundation with the one unpinned posture (mem-engine-scheduler-outbox): run_once issues no engine-issued heartbeat in delivery — the handover carries the raw claim deadline and the boxed JobHandle's own heartbeat stays available to the closure (renewal is the consumer's obligation). All other pins (boundary fire determinism, 64-cap catch-up + grid-honest skip-forward, no-double-fire, leadership contention/loss/clean-stop/lease-release, validation + @every grammar matrix, outbox ack/retry curve + derived name + unreachability) verified already present in scheduler.rs/outbox.rs's suite.

2026-10-10 12:18:25 +00:00

mem-engine-seam-tx.md

mem-engine-seam-tx — the wave's load-bearing seam lands: the complete Store/TxHandle trait surfaces over the guarded state core, with the tx overlay as the discipline centerpiece. Wider than the sqlite/pg seam twins by design (those rode pre-ported substrate ops and left mechanism methods stubbed; mem has no substrate, and the task's acceptance pins the full trait surfaces implemented over guarded state — a Rust trait impl is all-or-nothing per method): the seam task therefore realizes the mechanisms' committed-state effect layer and every mechanism handle itself, and the wave-6 mechanism tasks now own their acceptance-criteria unit pins against this foundation. Store surface: notify (codec-typed encode as the entry check only — the wake delivers the channel alone; PayloadTooLarge never produced, the ADR-016 §5 non-occurrence arm pinned at 2 MiB), listen (WakeReceiver bridge with the pinned recv forms; attach starts from now, one close path at engine drop), stream/queue/outbox/try_lock (validated constructors → boxed core-owned handle traits: the ADR-010 queue state machine with claims/reclaim-eats-attempt/uniform validity predicate/dead-letter/sweep + mem's third-owner equal-jitter curve — std-only RandomState hash jitter, no rand; ADR-015 log+offsets+trim+wake-driven subscribe; ADR-008 §7 TTL registry with renew-past-expiry refused; ADR-014 outbox helper with run_once ack/retry), schedule/unschedule/run_schedules (ADR-009 collapse: @every-only third-owner parser + register-table with pre-parsed interval and resolved stamps; the 64-cap bounded catch-up + grid-aligned skip-forward tick fired-and-advanced under one guarded op (schedules→queues lock order); leadership through the reserved __alkstore_scheduler lock with runner-unique owner, renew-before-tick, keep-awake sleep renewing on cadence, LeadershipLost / clean-stop-Ok returns). Tx overlay: begin_tx allocates the handle-private overlay; all eleven *_tx stage with entry-point validation before any effect, Codec-typed encode, one clock read, ADR-020 §3 stamp resolution (plain 300/3/5/none, outbox 60/5/5, the per-job max_attempts override via resolution.rs's stamps_with_override); tx reads merge overlay over committed (read-your-own-writes: queue-scoped + dead-visible get_job_tx, monotone staged saves, offset-ASC merged reads, extent guards clamping empty); commit consumes the handle, merges under one guarded op (queues→streams, the canonical lock order documented in state.rs), and fires the overlay's pending wakes AFTER the merge — wake-at-commit structural from birth (the pg-fix-tx-wake failure shape cannot exist here); drop (explicit, or through an unwinding panic — the overlay is plain local data, nothing runs on discard) = rollback with no ghosts, trivially. Stage-time id/offset allocation (the pg-shaped story — rolled-back allocations gap out; claims order id ASC, offsets immutable/never renumbered). Stream subscribers ride a reserved-prefix engine-internal wake channel (__alkstore_stream_wake:{stream}) unreachable by consumer entry points, attached before the stored-offset read; notify's transport stores nothing. 89 mem unit tests: the overlay discipline rows the task pins, the numeric-domain rows (extents/durations/boundaries/grammar/validation), and the mechanism smoke pins (the defect-class catch: ack/ack_batch originally deleted before checking the predicate — fixed; a refusal must leave the row exactly as it was). Manifest: serde_json = 1 joins (the trait signatures cross Value; both engine twins carry it; not a driver dep — wasm32 gate stays green). Task file: status completed, Notes (the whole-engine scope disposition + 11 decision-of-record entries incl. lock-renewal delta vs the sqlite substrate, ScheduleRow shape, runner lease mechanics, substrate predicate parity) + Summary filled. Verified: cargo build; workspace cargo test green (core 25, suite harness 3, mem 89, SQLite 191 lib + 25 suite, pg 124 lib + 25 suite + 9 schema); clippy --all-targets -D warnings clean; cargo fmt --check clean; cargo check --target wasm32-unknown-unknown -p alkstore-mem clean

pg queue/tx/notify dedupe + doc truth-telling: job_from_row has one owner (queue.rs, tx.rs imports it) and get_job_tx reuses live_columns()/dead_columns() instead of inlining the 18-column lists — the contract-pinned Job shape now has exactly one decode owner (ADR-012 §2); sweep_expired's doc states the moved + retention-deleted sum in the in_tx multi-statement frame (the sum the SQLite twin returns — the doc was the only liar); notify.rs's closed-store listen error routes through the shared database_error helper; bridge_capacity() is a const with its rationale doc carried. No behavior change — identical SQL strings, error shapes, and capacity. (task pg-fix-dedupe-cleanup, review 002 minor notes + Finding 6 queue bullet)

pg-fix-forwarder-diagnosability.md

pg: surface the forwarder's swallowed connect/poll failures (review 004 item 7's two narrow arms, pg-fix-forwarder-diagnosability) — output form per the ADR-025 decision of record: the reconnect arm's .ok() swallow at the loop's attempt closure becomes a tracing::warn! per failed connect (attempt index mapping the backoff state — 50 ms base doubling to the 2 s cap — plus the raw io-class connect error; reconnect_with_retry's generic signature and its two unit pins unchanged); poll_loop returns the fatal poll_message error instead of discarding it and the serve loop's poll-death arm surfaces the ending as a tracing::error! (fatal error, no-error stream close, and the join abort/panic variant — each naming the death and the stall-until-reconnect consequence); secret-free re-verified by grep — both new emission contents checked against the substrate (tokio-postgres 0.7.18 connect errors are Error::connect(io::Error), no DSN/user/password in Display; no subscriber-asserting test added, holding ADR-025's dev-dep stance); gates green: full crate suite against the harness server (135+25+9, all pre-existing forwarder/reconnect pins and the hardening task's pins green unchanged), workspace build/tests server-less, clippy -D warnings, fmt, doc gate, fuzz corpus replay 6/6; task -> completed

Wave-6 decomposition (mem engine): eleven tasks per the pg-wave rhythm — foundations (crate scaffold, MemStore::new isolation, guarded state core, wake routing, wasm32 gate from birth), seam-tx (the load-bearing tx overlay: eleven staged _tx methods, commit-merge + wake-at-commit — pg-fix-tx-wake's discipline structural from the start, drop = discard trivial, with_tx panic posture), mechanisms mutually parallel (notify-listen close-at-engine-drop/no-replay/never-coalesced; queues = ADR-010 machine driver-free with the equal-jitter curve and opts resolution as ADR-012 §2's third owner; streams log+offsets+trim; locks TTL registry, no busy-path analog), scheduler-outbox (tick/catch-up-64/leadership through the __alkstore_scheduler lock, engine-uniform per ADR-009 §4; outbox over queues with the 60/5/5 seam stamp), integration (suite third StoreFactory column green on host under a current-thread flavor, wasm32 acceptance items, engine-mem.md to implementation-complete), and the review-wave-6 gate (born-pinned audit: conformance read, discharge-map wiring, wasm items, three-way equivalence green, class-1 window discipline). Window riders: suite-harness-current-thread — the wave's one suite-side pre-task, past_stamp_sleep's blocking sleep goes async per review 003's properties.rs:1683 posture note, enabling the current-thread flavor; pg-fix-scheduler-tick-seam — review 003 Finding 1, the cfg(test) transient-fault seam driving the real tick_with_retries through retry-then-success and exhaustion arms (the last uncovered wave-4 hardening arm, sqlite-commit-error-arm pattern). Task hygiene: pg-fix-open-path frontmatter fixed (unquoted 'max_size: 0' colon-space inside the name scalar broke YAML parsing — taskgraph validate had been red one-error since the wave-4 fix-batch decomposition; also restores review-wave-4-fixes' dependency resolution). implementation.md: wave-6 table row → decomposed, task-set listing with the parallelism note (rider + pre-task independent of the mem chain; rider closes before the gate), wave-6 decomposition bullet in the review-rounds record.

pg-fix-scheduler-tick-seam.md

pg-fix-scheduler-tick-seam — the pg scheduler's transient-fault tick seam lands, retiring review 003 Finding 1 (MEDIUM: the tick retry loop was dead code under test — the last uncovered hardening arm of the wave-4 fix batch, the exact class review 002's live bugs came from). The seam follows the sqlite-commit-error-arm pattern of record: a cfg(test) per-store counting fault arm (crate::seam::tick_fault — Flag = Arc<AtomicU64>, born disarmed at 0, arm(n) adds, take() consumes one via CAS try_update; a counting arm because a boolean cannot reach the exhaustion arm — arm(TICK_RETRIES+1) faults the loop's whole budget while arm(1) leaves the later ticks real) feeding a fabricated pool/database-shaped opaque Database error into the REAL retry loop — both tests drive the full run_schedules → tick_with_retries → tick_once path end-to-end, no loop replication. Plumbing per the house pattern: cfg-gated tick_fault field on EngineCtx and PgStore (engine_ctx() carries the clone; production builds never materialize it), cfg-gated fault param on tick_once (the seam check sits before the real attempt — one attempt faults, never ticks) and tick_with_retries, cfg-branched attempt calls; PgStore::arm_tick_fault(faults) arming surface + tick_fault_flag() observation surface (a Flag clone so the consumption pin survives the store moving into a runner task). Two arms pinned: (a) one_faulted_tick_is_retried_and_the_job_fires — fault consumed on attempt 1, the 250 ms backoff sleeps, the retried attempt fires the backdated due boundary into the queue, exactly-one consumption, the runner survives the hiccup to a clean stop Ok(()); (b) tick_retry_exhaustion_exits_typed_and_leaves_the_lock_to_lapse — the exhaustion exits typed (opaque Database, never LeadershipLost; the tick-phase context rides the source chain with the fabricated fault at its bottom; wall-clock ≥ 1.7 s proving the real backoff window), the leadership lock row is left (not released) to lapse at its TTL (present, expiry bounded by the run's TTL horizon), exact consumption, and the store remains fully usable after — the "runner survives" pin as the module docs' contract states it. Replay-proofed live: with the seam's consumption disabled the exhaustion test cannot complete (the runner loops forever — no fault ever enters the budget; the mutated run's timeout is itself the proof); the test is then bounded (20 s) so a future regression of this shape fails, not hangs. LEADER_TTL_S widened private → pub(crate) for the lock-left-to-TTL expiry pin. Verified: full pg column live vs the harness (124 lib + 25 suite + 9 schema; new tests green solo ×3); cargo test --workspace green server-less, skips clean (core 25 + harness 3, sqlite 191 + 25); clippy --all-targets -D warnings clean; fmt clean; cargo-llvm-cov confirms the Finding-1 sites (the retry/backoff/exhaustion-arm region + the tick_once seam arm) carry zero missed lines; taskgraph validate green (61 tasks)

pg-fix-stale-unlisten.md

pg forwarder: generation-tagged commands — a reconnect drops its predecessor's queued commands before replaying, closing the stale-UNLISTEN window (a stale UNLISTEN replayed after the snapshot's re-issued LISTENs silently cancelled a re-registered channel, its wakes lost until the next reconnect); the reconcile decision is the pure helper (stale LISTEN and UNLISTEN dropped, current-generation commands replay in queue order, dropped stale LISTENs ack the transient mid-LISTEN error) pinned by a four-combination server-less unit test (replay-proven against the neutered shape); 'queued commands replay harmlessly' doc corrected and the post-reconnect LISTEN-set invariant (server LISTEN set = registry snapshot, dead-generation commands can't undo it) stated in the module + loop docs (task pg-fix-stale-unlisten, review 002 Finding 4)

pg-suite-infra-hardening.md

pg suite-infra hardening (task pg-suite-infra-hardening): the wave-4 review's F-1 defense-in-depth candidates — must_recv_event re-shaped from the 20 ms try_recv polling loop to a parked recv().await under the 15 s timeout wrapper (stream_tests.rs, the sole pg copy — SQLite twin untouched; the poll loop's wake-subscription interaction surface the F-1 flake suspected is out of the hot path, and the deadline assert still bounds the property). The parked form's terminal arms are explicit: Some(Err(e)) keeps the errored-instead-of-idling panic, None gets a receiver-closed panic the poll form never saw. The deadline miss self-diagnoses (the small-honest realization of candidate (b)'s discriminator): read_since(offset, 1000) over rows beyond the receiver's position names the residual class — rows durable undelivered (wake/re-drain class) vs no rows (publish-visibility class); with the parked recv a wake-arrived-but-re-drain-missed arm is structurally implausible (only a read error could miss, and it surfaces Err). Candidate (b)'s literal bridge-side counter skipped, reason recorded in the task (surfacing the bridge wake count across the dyn EventReceiver boundary needs downcast/keyed-global machinery beyond the small-honest bar); the small honest piece did land: wait_wake's Lagged(n) arm now logs (eprintln, house posture matching notify.rs's bridge_loop — and forwarder.rs's 'the receiver bridge's Lagged arm logs / recovers' doc claim now true at both bridges), stream name threaded into wait_wake's signature so the log attributes the lag. Verified: pg stream module 21/21 vs harness server (full module run), tx_publishes_compose_with_the_handle 5 solo re-runs green (determinism re-check under the parked shape), two consecutive full pg harness runs green (121 lib + 25 suite + 9 schema, ~72 s each), cargo test -p alkstore-postgres green server-less (skips clean), workspace cargo test green (12 binaries), clippy -D warnings, fmt clean

review-wave-4-fixes.md

pg-fix-scheduler-fire-wake — the scheduler tick's fire wake lands, closing the recorded cross-engine fire-wake latency-parity gap (the wave-5 gate's one standing item, review-wave-4-fixes' recorded-for-later note): scheduler.rs::tick now issues one coalesced pg_notify per firing schedule per tick after the fire loop, still inside the tick's in_tx frame — channel = the fired queue's name (schedule() rejects reserved names per ADR-021 §3, so the plain queue name is always the right channel), empty payload (Wake { channel } only, ADR-008 §3), best-effort via the shared tx::wake_tx (widened private → pub(crate) per the recorded one-call shape; enqueue_row stays wake-free — no double-wake; auto-commit Queue::enqueue and the tx producer paths untouched). NOTIFY's native transactional delivery makes the wake commit-atomic: a rolled-back tick (crash mid-tick ⇒ boundary refires) discards the wake with its fire rows — the tx/no-ghosts discipline the tx producer paths already pin; coalescing default one-per-firing-schedule-per-tick (not per-fire) matching the SQLite watcher's per-committed-tick cadence, decision recorded in the task's Notes. New four-arm pinning test (scheduler_tests.rs, tx_producer_wakes_are_commit_atomic pattern): pre-commit silence inside the runner's own in_tx frame driving the engine's own tick (rogue-ticks shape), deterministic delivery at/after commit, coalescing (≥2 boundaries → one wake), nothing-due silence (same-tick not-due schedule + a later all-not-due tick, in-frame and post-commit), and the end-to-end runner leg (a live run_schedules leader's wake reaches a registered listener); local listener_hears helper per the per-file helper convention; rollback arm native (NOTIFY transactional delivery — no tick-fault seam built, per the task pin). Docs: tx.rs 'The tx wakes' section + wake_tx doc name the scheduler fire path as a shared caller; scheduler.rs module docs + tick doc pin the coalesced commit-atomic semantics. Record updates: review-wave-4-fixes' recorded-for-later bullet, suite-scheduler-rows' gate disposition note + Notes bullet, review-wave-5 §Notes 4's audit row — all retired with pointers; implementation.md gains the review-rounds line (fires visible to registered listeners ahead of the mem engine's posture being written). Also carried: review-wave-5 §6 flake-ledger update — row_lock_ttl_expiry_and_reacquisition failed once more in a full pg run this session (green on the next two full runs + six focused; unrelated mechanism to this change), meeting the ledger's own 'fails again' trigger with the dedicated investigative session owed by the wave-7 watch carriage. Verified: full pg lib suite 122/122 vs the harness (new test green ×3 solo); pg contract suite 25/25 + schema 9/9; workspace cargo test green server-less (pg skips clean incl. the new test); clippy --all-targets -D warnings clean; fmt clean

sqlite-commit-error-arm.md

SQLite commit-error-arm coverage (task sqlite-commit-error-arm): the wave-3 review gate's deferred test landed — failed_commit_replenishes_the_writer_slot drives a failing COMMIT through the engine's commit path and pins the review's code-read fix end-to-end: the error surfaces as the opaque Database carrying the SQLITE_FULL-shaped source chain, the failed connection is dropped and the writer slot replenished via the handle's reopen closure (the next begin_tx proceeds within a bounded timeout, no parking — the store-wide-livelock posture), no partial-commit residue (the dropped connection's uncommitted writes read back None), the post-failure commit is a real clean commit (the fault disarms on consumption), and auto-commit notify works afterward. Injection is a cfg(test) commit-fault seam in seam.rs — a per-store Arc<AtomicBool> arm (born disarmed, armed via arm_commit_fault, take() disarms on first consumption so exactly one commit faults) whose fabricated rusqlite SqliteFailure feeds the production commit error arm rather than replicating it; the PRAGMA max_page_count route was probed live against both WAL and DELETE journal modes first and rejected: SQLite checks the page-count limit at page-allocation time, so the squeeze always fails the growth statement (SQLITE_FULL/DiskFull on the first INSERT) and leaves no transaction active for COMMIT to fail — the arm is unreachable through PRAGMA-space (also probed: the pragma is per-connection, so pre-begin arming on the writer conn would have ridden into the tx conn; the route failed on error placement, not delivery). Mechanism choice and probes documented in the seam doc comment and the task Notes. Cross-test safety is per-store scoping; parallel stores never see the arm. Replay-proofed live: with the error arm's writer_reopen replenish temporarily removed the test fails (begin_tx parks past the 5 s timeout — the stranding the review identified), reverted it passes. Plumbing follows the pg-fix-forwarder-reconnect cfg(test) precedent: fields on SqliteStore/SqliteTxHandle and a begin param are cfg-gated, production builds compile the plain path. The waves-1-2 review's optional watcher reconnect-success add rides here (taken — recorded in Notes): reconnect_success_resumes_wake_delivery drives run_poll_loop through its existing open_conn_fn seam (same instrument as the W-1 failure test), with the db file present throughout because the vanished-file route cannot reach the success body (file reappearance trips the dead-man's identity switch first): initial open + first two reconnects fail by injection, the third reconnect succeeds, and a subsequent commit wakes on_change — the success arm's data_version re-baseline and restored delivery pinned. Watcher shape untouched. Verified: cargo test -p alkstore-sqlite green server-less (191 lib + 25 suite), workspace cargo test 399/0, clippy -D warnings, fmt clean

sqlite-fix-listener-bridge-alignment.md

sqlite: the listen bridge takes the stream bridge's std-thread shape (review 004 item 8) — one dedicated named thread per subscription doing blocking_send, not a spawn_blocking task (past ~500 listeners the blocking-pool ceiling queued the whole engine's seams); spawn failure unsubscribes and fails closed with Error::Database, matching the stream bridge's posture; notify.rs + engine-sqlite.md docs aligned; task -> completed

sqlite-fix-scheduler-error-classification.md

sqlite: run_schedules' failed-renewal arm classifies as Database, never LeadershipLost (review 004 item 9) — a lost lease (Ok(false)) keeps the respawn arm unchanged; a failed renewal (closed store / storage failure) propagates its opaque classification, so respawning misdirects at a dead store no more; dated (2026-10-11) ADR-017 §2 class-1 annotation of the loss-vs-failure arm set in ADR-009 §1, core-contract §Errors, queues.md, engine-sqlite.md, core+sqlite doc comments; two tests pin both arms; pg twin recorded for follow-up; task -> completed

sqlite-fix-watcher-death-subscribe.md

sqlite: dead-watcher subscribe fails closed + initial-stat identity-unknown baseline (review 004 items 2+3) — the poll loop sets a dead sign before the watcher-fatal exit and subscribe() fails closed on it (and the taken watcher slot) atomically with enrollment; listen/stream subscribe map it to Error::Database, never park on a dead feed; the identity baseline is Option-tracked so a failed startup stat no longer seeds the (0,0) false identity that a transient recovery would trip into death; engine-sqlite.md posture covers both arms; PROVENANCE D-39; task -> completed

suite-lock-rows.md

Contract-suite lock rows (task suite-lock-rows): two version-stamped rows discharging the lock backlog rows — lock_ttl_expiry_and_reacquisition (the ADR-008 §7 guarantee row: a held lock excludes a second acquirer (contender None); after a 1 s TTL the exclusion lapses silently — no revocation event, no error — and a second owner acquires; the original holder's post-expiry renew is refused (false, the lost-it arm); the second owner's release frees the name for a third acquirer, which consumes cleanly; tolerance-sleep posture, state outcomes only; ADR-008 §7 + ADR-019 §1, duration-guard legs cross-referenced to duration_refusal_on_non_positive_ttl) and concurrent_try_lock_loser_is_a_value (the contention posture: four sequential contenders — two owners, repeated — against a held lock all land the clean None value, never Database, never a busy-throw; the backlog row's SQLite busy-path open question answered: no divergence from the pg reference; release-then-contend cycle proves the loser path leaves no state blocking a later acquire, granted to a former loser and consumed cleanly; ADR-008 §5 + §7 + ADR-019 §1) — wired into both engines' suite targets (SQLite tokio tests, pg harness_row!s), 23 rows per column up from 21. Dispositions in Notes: no divergence found (no fix/ADR call needed), ADR-023 §2 excluded from stamps (its guard property is the duration-refusal row's, cross-referenced), the backlog parenthetical re-acquire-does-not-refresh-TTL stays engine-pinned, renew-refusal asserted after the second owner's re-acquisition (strongest form), contenders distinct-owner only (same-owner re-acquire grants per the inherited substrate shape), and one unreproducible first-cold-run pg failure recorded (message lost to truncation; 13 subsequent clean runs incl. concurrent SQLite+pg — no timing hazard identified, the lapse assertions are post-sleep state outcomes). Drive-by: alkstore-contract-suite's tokio dep gained the macros feature — a pre-existing compile break in the crate's own tests/suite_harness.rs (since 7f749ac) failed the harness target and the workspace test gate on HEAD; test-side non-event (ADR-017 §2 class 4). Verified: cargo test -p alkstore-sqlite -p alkstore-postgres green (SQLite 121+23+9, pg 189+23 vs harness server on :15432, server-less pg skips clean), workspace cargo test green (12 binaries), clippy -D warnings, fmt clean

suite-opts-backoff-rows.md

Review gate — wave-5 suite passed (task review-wave-5): the suite stands as the compatibility instrument and the engine specs flip to stable. All 25 mechanism rows per engine column read in full and verified against core-contract.md §Verification backlog item by item (the appendix map's every claim confirmed by the pinning row/text, incl. the combined-coverage claim for save_offset_tx exactly-once and the five engine-side pins — SQLite open row, watcher-cadence knob, M-1 sweep-rollback: SQLite trigger seam live + the pg frame's in_tx structure code-read; beyond-64 skip-forward; cap-curve); all 25 'Contract stamp:' markers checked against the cited ADR § bodies (ADR-008 §3/§5/§7/§8, 009 §1/§3/§4/§6, 010 §1-§5, 014 §1, 015 §1-§5, 016 §5, 020 §1-§4, 021 §1/§3/§4/§5, 023 §1/§2, 012 §2, 019, 007, 006) — the enqueue_opts_resolution amendment accumulation rides ADR-023 §2 per the convention; all six parked dispositions audited and recorded (M-1 engine-side, skip-forward engine-side twins, cap engine-side, fire-wake parity not demanded, lock busy-path no divergence, reconnect-success test taken); conformance spot-checks clean (no row pins beyond ADR text, determinism posture holds incl. the two documented extensions, cross-references not duplication). Green on both engines this session: workspace build/test/clippy -D warnings/fmt; SQLite column 25/25 server-less twice (isolated + concurrent); pg column 25/25 vs the harness server three full runs (two consecutive + one concurrent with the SQLite column) plus 6 focused --test-threads=6 stress runs of the two development-time flake rows — all clean, the two unreproducible pg failures recorded with the bounded investigation and a wave-6 watch flag in the task's Notes. Docs: engine-sqlite.md and engine-postgres.md frontmatter status draft → stable with dated annotations citing this gate; implementation.md wave-table row 5 and review-rounds entry; suite-opts-backoff-rows.md placeholder remnants removed. Wave 6 (release readiness) decomposition may proceed

suite-queue-depth-rows.md

Contract-suite queue-depth rows (task suite-queue-depth-rows): the job-handle validity predicate row (in-window heartbeat/ack landing, late-heartbeat/post-lapse-ack/retry/fail refusals past a 1 s stamp with the row untouched, ack_batch per-id predicate live-1/lapsed-0/nonexistent-0, fail(None)→"failed" and retry-at-budget→"max attempts exceeded"), the ADR-010 depth row (reclaim consumes an attempt with claimed_at/deadline refreshed and the original holder refusing, reclaim-exhaustion dead-lettering with the pre-claim sweep — get_job-visible "max attempts exceeded"+died_at, cancel unconditional delete with the not-an-interrupt refusal shape plus pending/dead/missing arms), and the no-stranded-rows sweep row (both states move with "expired", unexpired/never-expiring untouched, retention TTL enforcing with the moved+deleted sum, None=forever) — each version-stamped per the suite convention (ADR-010 §1–§5, ADR-019 §3, ADR-008 §5), wired into both engines' suite targets (SQLite tokio tests, pg harness_row!s). M-1's retention-failure pin dispositioned engine-side per the task's honest call: the storage-level DELETE failure is not injectable through the contract surface, so it lands in the SQLite substrate's trigger seam (sweep_rolls_back_the_retention_half_with_the_move — the move half rolls back with the retention half), with the pg twin verified structurally (both halves inside in_tx's frame) and the disposition recorded in the task Notes. Verified: sqlite suite 13/13, pg suite 13/13 vs harness twice (postgres/poc@:15432), substrate sweep-rollback tests 4/4, workspace build/test green, clippy -D warnings, fmt clean

suite-scheduler-rows.md

pg-fix-scheduler-fire-wake — the scheduler tick's fire wake lands, closing the recorded cross-engine fire-wake latency-parity gap (the wave-5 gate's one standing item, review-wave-4-fixes' recorded-for-later note): scheduler.rs::tick now issues one coalesced pg_notify per firing schedule per tick after the fire loop, still inside the tick's in_tx frame — channel = the fired queue's name (schedule() rejects reserved names per ADR-021 §3, so the plain queue name is always the right channel), empty payload (Wake { channel } only, ADR-008 §3), best-effort via the shared tx::wake_tx (widened private → pub(crate) per the recorded one-call shape; enqueue_row stays wake-free — no double-wake; auto-commit Queue::enqueue and the tx producer paths untouched). NOTIFY's native transactional delivery makes the wake commit-atomic: a rolled-back tick (crash mid-tick ⇒ boundary refires) discards the wake with its fire rows — the tx/no-ghosts discipline the tx producer paths already pin; coalescing default one-per-firing-schedule-per-tick (not per-fire) matching the SQLite watcher's per-committed-tick cadence, decision recorded in the task's Notes. New four-arm pinning test (scheduler_tests.rs, tx_producer_wakes_are_commit_atomic pattern): pre-commit silence inside the runner's own in_tx frame driving the engine's own tick (rogue-ticks shape), deterministic delivery at/after commit, coalescing (≥2 boundaries → one wake), nothing-due silence (same-tick not-due schedule + a later all-not-due tick, in-frame and post-commit), and the end-to-end runner leg (a live run_schedules leader's wake reaches a registered listener); local listener_hears helper per the per-file helper convention; rollback arm native (NOTIFY transactional delivery — no tick-fault seam built, per the task pin). Docs: tx.rs 'The tx wakes' section + wake_tx doc name the scheduler fire path as a shared caller; scheduler.rs module docs + tick doc pin the coalesced commit-atomic semantics. Record updates: review-wave-4-fixes' recorded-for-later bullet, suite-scheduler-rows' gate disposition note + Notes bullet, review-wave-5 §Notes 4's audit row — all retired with pointers; implementation.md gains the review-rounds line (fires visible to registered listeners ahead of the mem engine's posture being written). Also carried: review-wave-5 §6 flake-ledger update — row_lock_ttl_expiry_and_reacquisition failed once more in a full pg run this session (green on the next two full runs + six focused; unrelated mechanism to this change), meeting the ledger's own 'fails again' trigger with the dedicated investigative session owed by the wave-7 watch carriage. Verified: full pg lib suite 122/122 vs the harness (new test green ×3 solo); pg contract suite 25/25 + schema 9/9; workspace cargo test green server-less (pg skips clean incl. the new test); clippy --all-targets -D warnings clean; fmt clean

suite-stream-rows.md

Contract-suite stream rows (task suite-stream-rows): two version-stamped rows discharging ADR-015's backlog legs — stream_ordering_equivalence (a keyed/unkeyed interleaved publish sequence of 6 reads back in the same order on every read form: whole + cursor-paginated + mid-stream read_since, read_from_consumer fresh and from a mid checkpoint, and a subscriber's attach drain; offsets strictly increasing per stream — per-stream relative order, absolute values explicitly not cross-pinned (pg bigserial vs SQLite AUTOINCREMENT); key round-trips exactly None/Some on every read form including the explicit-None keyed publish form; stream carries the name; created_at tolerance-bounded informational, never an ordering assertion; ADR-015 §4/§3/§1, byte-exactness and tx-seam legs cross-referenced to the payload-round-trip and keyed-tx-atomicity rows) and trim_to_semantics (the full ADR-015 §5 row: exact-boundary trim — the horizon's own row deletes, horizon+1 survives, repeated trim 0; survivors keep offsets; reads from a trimmed-away region resume at the horizon's first remaining row; a below-horizon saved checkpoint stays a get_offset-visible position marker with read_from_consumer and a fresh subscribe both resuming at the horizon, never a renumbered past; a pre-trim subscriber's above-horizon checkpoint keeps its place; a pre-attached listener idles across the trim in a 400 ms bounded window — no dedicated wake, SQLite's spurious watcher hint contract-legal and delivering nothing; ADR-015 §5/ADR-019 §6, negative-horizon/immutability legs cross-referenced to extent_clamp_semantics). Wired into both engines' suite targets (SQLite tokio tests, pg harness_row!s). Dispositions in Notes: the attach-drain pattern leads with a blocking recv() before the try_recv drain (engines deliver the attach read asynchronously); the pg LISTEN channel is mechanism-named and database-wide so concurrent suite rows' wakes cross schemas — safe by construction (wakes re-drain own-schema storage only, delivering nothing), no "events" rename needed. Verified: sqlite suite 21/21, pg suite 21/21 vs harness (postgres/poc@:15432, 7 consecutive full runs), 5 focused --test-threads=6 runs of the two rows per engine, workspace build/test green, clippy -D warnings, fmt clean

suite-tx-commit-atomicity-rows.md

Contract-suite tx commit-atomicity rows (task suite-tx-commit-atomicity-rows): the N-5 panic-probe admission in properties.rs's module doc (spawned with_tx task joined via JoinError::is_panic — catch_unwind around an async closure cannot see the panic point across an await; post-panic assertions read-only until convergence, single-task drive, no race window; ADR-017 §2 class 4) and three version-stamped rows: outbox_enqueue_tx_commit_atomicity (rollback drops the backing-queue job with the business write — get_job_tx-gone + run_once claims nothing; commit makes the job claimable exactly when the business write commits, real delivery through the RecordingDelivery closure with job-id identity, derived __alkstore_outbox:mail queue, exact payload, 60/5/5 stamps, consumed-after-ack; ADR-014 §1, ADR-010 §3a, ADR-021 §4, ADR-007), publish_with_key_tx_commit_atomicity (rollback drops the keyed event with the business write, key round-tripping inside the tx; commit surfaces it to read_since and a post-commit subscriber attach with the key round-tripping; ADR-015 §2/§4, ADR-021 §4, ADR-007), and with_tx_panicking_closure_rolls_back (N-5's probe against real engines: the panicking closure writes all four kinds then panics mid-flight; panic surfaces via the join; no-ghost reads converge with begin_tx granting every iteration; pre-panic listener silence on the notified channel; ghost never claimable; fresh with_tx commits through the same seam — both engines green; ADR-007, ADR-021 §4) — wired into both engines' suite targets (SQLite tokio tests, pg harness_row!s). Dispositions recorded in Notes: the 60/5/5 stamp inspection rides the delivery handle's job() because get_job cannot target the reserved derived backing queue through the contract surface (exemplar row pins the rejection; engine-side raw-row probes stayed put), the panic row's notify leg is a windowed silence (SQLite's wake overtriggers on any commit — the fully cross-engine notify-ghost pin rides the engines' rollback-ghosts twins, the suite's drop-rollback row made the same call), the closure tail routes through a #[cold] mid_flight_panic -> Error helper (a bare Err(panic!()) tail trips unreachable_code under -D warnings), and the post-panic convergence loop is the suite-side bounded wait (state outcomes only, begin_tx doubling as the seam-still-grants probe). Verified: sqlite suite 19/19, pg suite 19/19 vs harness twice (postgres/poc@:15432) + solo re-runs of each new row per engine (determinism), workspace build/test green, clippy -D warnings, fmt clean

suite-wake-rows.md

Contract-suite wake row (task suite-wake-rows): wake_receiver_shapes — the wake contract's pinnable core, tolerance-bounded to state outcomes (never delivery counts or latencies): a pre-attached listener receives a wake after a committed notify on its channel through all three recv forms (recv/try_recv/recv_timeout), every wake's channel field matching the listened channel (the one piece of semantic content a wake carries, ADR-008 §3); a three-notify burst floors at one wake — never an exact per-notify count (coalescing the documented engine asymmetry: SQLite's 1-slot feed vs pg per-notify, the row pins the floor not the shape); a listener attached after a commit never sees that commit's notify — recv_timeout idles a 400 ms absence window (a 300 ms pre-settle sleep closes SQLite's watcher baseline race: the last_version baseline is store-open-captured, so an unconsumed commit's version change would fire one late tick at the new subscriber indistinguishable from replay; pg's gap-commit no-replay hole and SQLite's burst coalescing both legal under the pin); and the channel-scoped leg — a foreign-channel notify never surfaces a wake naming it (SQLite's same-commit overtrigger may deliver but carries only the listened channel; the pg LISTEN fanout skips foreign channels; the reserved reconnect straggler tolerated), with a same-channel positive control proving the silence is scoping not a dead listener. The failure-surface close arms (SQLite watcher-death recv()->None, pg synthetic reconnect-wake) stay pinned engine-side and in receiver_close_and_save_arms's disposal leg — cross-referenced in the doc comment, not re-pinned. Stamped ADR-006 + ADR-008 §3. Wired into both engines' suite targets (SQLite tokio test, pg harness_row!), 24 rows per column up from 23. Dispositions in Notes: the backlog row stays in core-contract.md's inventory (flushes at review-wave-5's stable gate, like the other discharged rows), the absence windows are single recv_timeout calls (the documented Ok(None) idle arm as the bounded wait), and the scoping leg's observable is the channel field not absence (SQLite overtrigger makes an absence-only pin vacuous there). Verified: SQLite column green server-less, pg column green vs harness (postgres/poc@:15432), 3 solo re-runs of the row per engine (determinism), cargo test -p alkstore-sqlite -p alkstore-postgres green (SQLite 189+24, pg 121+24+9), workspace cargo test green (12 binaries), clippy -D warnings, fmt clean
