glm-5.3-flash ed883e06ea General review, wave 5 (docs/reviews/003): no correctness or security defects; findings are coverage-side — the pg scheduler's transient-error retry loop never executed under test (seam recommended for wave 6), forwarder race arms and SQLite rollback-failure arms parked, suite-overpinning and engine-row wiring cross-checks clean. Verified this session: workspace gates green server-less and the full pg column live vs the harness (121 lib + 25 suite + 9 schema), cargo-llvm-cov full-workspace inventory recorded (core 100%, suite 97.1%, sqlite 95.0%, pg 92.9%)

alkstore-contract-suite

Contract-suite rows (task suite-opts-backoff-rows): the backoff-curve equivalence row and the deferred enqueue-opts clock legs. backoff_curve_equivalence — the equal-jitter exponential pinned as the range, not a jitter label (ADR-010 §3): claim → retry(err, None) cycles on a backoff_base_s = 2 queue land the ranges [1,2], [2,4], [4,8] across attempts 1–3, each computed delay read back through get_job's resolved run_at minus a clock read taken before the retry — the lower bound race-free (the retry's internal clock read cannot precede the suite's, so the observed value over-reads the delay, never under-reads) and the upper bound carrying a one-second straddle tolerance for the integer-second stamp crossing a wall second; identical bounds on both engines is the equivalence pin (ADR-012 §2, the row body shared). The explicit-delay override legs ride the same row: retry(err, Some(5)) honored verbatim ([5, 6] under the same straddle tolerance) and retry(err, Some(0)) resolving ready-now per the boundary-total rule (ADR-023 §2), claimed within a bounded wait. enqueue_opts_resolution extended in place with the wave-5 legs its deferral note named — the run_at-alone literal leg (a future run_at is the row's ready time verbatim, a deterministic equality with no clock read involved; a past run_at stores the literal too and is claimable now through the run_at <= now predicate within a bounded wait, the run_at-ASC ordering making the observation unambiguous among the row's other legs) and the neither-field leg (ready at the enqueue instant, abs_diff(now) <= 5 tolerance-bounded proximity, never a tight timing assert); the deferral note replaced by the completion statement, ADR-023 §2 stamp accumulated per the convention (ADR-020 §1 governs the resolutions). Cap-leg disposition recorded in Notes for the review gate: the 1-hour cap is not suite-pinnable (capped attempts need minute-scale waits) and stays pinned engine-side on both engines' unit tests per the wave-3/4 reviews. Ready-now waits are bounded claim_one poll loops (deadline asserts only, sequential single-store drive), with the one draft defect the finding surfaced (a re-claim after the bounded wait consumed nothing; the helper returns the claimed handle) noted. Wired into both engines' suite targets (SQLite tokio test, pg harness_row!), 25 rows per column up from 24. Verified: SQLite column green server-less (25/25 suite, 189 lib), pg column green vs harness (postgres/poc@:15432 — 25/25 suite, 121 lib + 9 schema), 3 solo re-runs of each new/extended row per engine (determinism), server-less pg skips cleanly via the reachability gate, cargo test -p alkstore-sqlite -p alkstore-postgres green, clippy -D warnings, fmt clean

alkstore-postgres

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

alkstore-sqlite

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

tasks

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
