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

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).

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

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

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).

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).

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.

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

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
