 ## Notes
 
-> To be filled by implementation agent
+Review performed 2026-10-11 (opencode, glm-5.3-flash). Gate checklist
+record — every disposition verified against the review's failure
+mechanism by code-read, not test-name-trust:
+
+- **1 (seam panic-safety)**: the armor is real, and the test *injects*
+  rather than simulates — `store/seam_tests.rs` passes panicking
+  closures directly into the `pub(crate)` seams; `WriterLease`/`
+  ReaderLease` (seam.rs) own the connection via `Option` + `Drop`, and
+  the unwind arm is `Writer::replenish()` (path-based fresh bootstrapped
+  open, matching the tick's established arm; failed replenish tolerated
+  with a diagnosability event) and `Readers::abandon()` (outstanding
+  decrement — the accounting precises out because every connection
+  carries its fresh-open increment for life — with the waiter notify
+  under the pool lock). Post-unwind assertions are behavioral: slot
+  re-acquired, `max_readers: 1` pool re-acquires, full store op
+  succeeds. The Notes' design of record matches what landed.
+- **2 (watcher death + initial-stat)**: `run_poll_loop` sets the dead
+  sign before the identity-replacement fatal return, and `subscribe`
+  fails closed on it *and* the taken watcher slot atomically with
+  enrollment under the senders lock (the belt-and-braces second arm
+  recorded in Notes, matching). The identity baseline is
+  `Option<(u64, u64)>` — a failed startup stat leaves it unknown and
+  the first successful stat captures without driving death. Four new
+  tests (substrate + engine-level fail-closed, the injected-failure
+  aliveness drive unix-gated because non-unix `stat_identity` cannot
+  fail), and the pre-death close-at-death pins checked green.
+- **3 (bridge alignment)**: `listen`'s bridge is now a named
+  `std::thread::Builder` thread (`alkstore-listen-bridge-{channel}`)
+  — the stream bridge's shape exactly, including the spawn-failure
+  unsubscribe-and-fail-closed arm; no residual difference is left
+  unjustified (the Notes name the spawn-failure arm as adopted, not
+  residual). `listen_after_watcher_death_fails_closed` surfaces
+  identically through the aligned bridge.
+- **4 (scheduler classification)**: both engines' loop-top renew is a
+  three-way match — `Ok(false)` keeps `Err(LeadershipLost)`
+  return-before-tick, `Err(e)` propagates its opaque classification
+  (closed store arrives pre-classified `Database`, engine-wide posture)
+  — the `.unwrap_or(false)` flattening gone on both, the two pin tests
+  (`closed_store_run_reports_the_closed_classification_not_leadership_
+  lost`, `mid_run_lease_loss_still_returns_leadership_lost`) present on
+  both engines, and the dated 2026-10-11 ADR-009 §1 annotation of
+  record verified engine-neutral.
+- **5 (substrate SAFETY comments)**: all **ten** `unsafe { ctx.
+  get_connection() }` sites carry concrete-invariant comments (the
+  eight review-scoped + the same-class `schema.rs:104` notify
+  registration + the test-module probe), and the diff-fidelity posture
+  is honored — PROVENANCE delta **D-40** (category `hygiene`) is
+  registered with the derived rusqlite #643 soundness argument. This
+  was the check that mattered most here; it passes.
+- **6 (forwarder hardening)**: the TOCTOU restructure is real
+  decide-and-queue — `ChannelSet::enqueue_register`/
+  `enqueue_unregister` make the refcount decision, the `connected`
+  read, the generation-tag load, and the command enqueue one critical
+  section under the registry guard (poison-recovered), with the ack
+  awaited *outside* the guard (never a std lock across an await);
+  the queue's order is thus the registry transitions' linearization.
+  The two hang arms are bounded by `bounded_wait` (biased toward the
+  shutdown flip): the verify batch and the serve/replay commands ride
+  `LISTENER_QUERY_TIMEOUT` (5 s), the failed-verify settle rides
+  `LISTEN_SETTLE_TIMEOUT` (2 s) with an unsettled reaper aborted
+  (the connection closes with it). Preserved postures re-verified
+  green: the register-failure/subscribe-failure unregisters in place
+  (notify.rs both arms), the poison-recovery idiom throughout, the
+  replay-proofs recorded in the task's Notes (the pin fails on the
+  review's exact assert with the fix reverted). The Notes' thread-
+  preemption window analysis matches the landed guard placement.
+- **7 (log facade + diagnosability)**: ADR-025 exists with the user
+  sign-off recorded in its status (tracing adopted, engine crates
+  only, core dep-free and emit-free); zero library-path `eprintln!`
+  remain (grep), both engines carry `tracing = "0.1"`; the two
+  diagnosability arms emit in the decided form (`warn` on failed
+  reconnect connects with attempt/backoff context, `error` on the
+  poll-exit endings); the secret-free grep re-run clean (the remaining
+  `.ok()`s are tests' env plumbing).
+- **8 (BIGINT stamps)**: the decided guard at the decided sites as one
+  owner — `resolution.rs::saturating_stamp_expr` called at exactly the
+  decision's six sites (queue claim/retention/retry/heartbeat, lock
+  insert/renew) with the `($N::bigint)::numeric` chain (the live-caught
+  `WrongType` refinement recorded in the owner's doc); the decision
+  task (ADR-023 §2 dated annotation, window verified open) and the
+  implementation task both green against the harness server, no
+  re-deciding — the one refinement is recorded, not deviated around.
+- **9 (mem doc notes)**: `engine-mem.md` carries the new growth-postures
+  section (both postures anchored to `stream.rs`/`queue.rs` sites) and
+  the outbox-semantics subsection ("processed means delivered-or-
+  reclaimable"); the `debug_assert!` declined with a real
+  false-positive rationale recorded (in-closure handle ops would
+  trip it).
+- **10 (offset pre-yield pin)**: the three-way verification evidence
+  exists — the suite row `receiver_offset_pre_yield_is_zero` (four
+  arms incl. the ADR-023 §2 negative-seed arm and the first-observation
+  composition leg), green on all three columns; the contract text
+  pinned in three places (core-contract.md's streams row + verification
+  backlog, the trait doc — no divergence to raise, so the AC's
+  divergent branch correctly unticked as N/A).
+- **11 (Display forging)**: `display_safe` (per-char `escape_debug`)
+  in the four `Display` arms (`InvalidName`/`ReservedName`/`InvalidSpec`
+  + `Codec`, the same-class neighbor the task's grep found); the
+  escaping test pins zero emitted control bytes; the taxonomy
+  (variants/fields/match sites) byte-identical.
+- **12 (identifier note)**: the note is in the release text —
+  deployment.md (dated, at the pg co-tenancy paragraph) and
+  engine-postgres.md — with the accuracy sharpening recorded (the
+  server rejects ≥ 64-byte `pg_notify` channels; the collision is on
+  the registration side); the no-cap validation verdict untouched.
+- **13 (tokio dev-deps)**: the three engines' `[dev-dependencies]`
+  tokio feature sets are identical
+  (`rt-multi-thread + macros + time + test-util`); tests green.
+
+**No regressions (re-spot-checked at the touched sites)**: the tick's
+`drop-+-replenish` disposition intact (`(out, conn, poisoned)` + the
+commit/rollback-fault seams); the tx-form negative seed intact (pg
+`save_offset_tx` stores raw, no `GREATEST`; mem's `has_offset_row`
+probe distinguishes the absent checkpoint); the sleep caps (`MAX_SLEEP_S`
+30-day cap on all three engines); the sqlite claim stamp's
+`saturating_add` (scheduler.rs:346); the register-failure/subscribe-
+failure unregisters; the poison-recovery lock idiom; `encode_payload`'s
+127-container depth limit; the doc corrections.
+
+**Records landed this gate**: review 004's sixteen
+`Findings recorded, not fixed` items annotated with their dispositions
+and task pointers (the record reads closed);
+`implementation.md`'s review-rounds entry for the batch; the task-file
+audit — all sixteen dependencies `completed`, Notes and Summary filled.
+
+**Minor records issues found and fixed inline (comment/metadata only)**:
+- stale placeholder lines (`> To be filled …`) left above real content
+  in two batch task files (`sqlite-fix-watcher-death-subscribe`,
+  `sqlite-fix-listener-bridge-alignment`) — removed; the identical
+  pre-existing residue in three earlier completed tasks
+  (`review-wave-3`, `release-readme`, and — noted by `review-wave-5`
+  itself as the class's precedent — same shape) cleaned in the same
+  stroke.
+- completed-AC checkboxes left unticked on five batch tasks
+  (`sqlite-fix-seam-panic-safety`, `sqlite-substrate-safety-comments`,
+  `mem-doc-growth-outbox-notes`, `normalize-tokio-dev-deps`, `pg-fix-
+  scheduler-error-classification`) — ticked after this gate verified
+  each; the one intentionally-conditional divergence AC
+  (`core-pin-offset-initial-value`'s) left unticked as N/A.
+- the gate task's own description said "fifteen tasks"; corrected to
+  the honest sixteen (the pg twin added mid-batch).
 
 ## Summary
 
-> To be filled on completion
+**Review gate passed: all sixteen dispositions verified against
+review 004's failure mechanisms by code-read; the inline fixes'
+pinned postures re-spot-checked with no regressions; records landed;
+all gates green.**
+
+Highlights (full checklist in Notes):
+
+- Findings 1–4: the armor/state-machine changes are structurally what
+  the tasks' Notes of record pin (lease Drop arms, the dead sign, the
+  two bridges' aligned shapes, the twin three-way renew matches) — and
+  every injected-panic / death-injection / interleave test drives the
+  real mechanism, not a simulation.
+- Finding 5's PROVENANCE delta D-40 (the diff-fidelity posture's
+  purpose) verified; Findings 6–11's behavioral shapes confirmed
+  (decide-and-queue under the registry guard, `bounded_wait` at every
+  listener await, the `saturating_stamp_expr` six-site owner, ADR-025's
+  decided emission form, the three-place offset pin, the display
+  escaping).
+- The batch's own honest-record trail held up under audit — every
+  Notes section (design of record, form refinements, declined
+  alternatives like mem's `debug_assert!`) matches what landed —
+  with three minor record-hygiene defects fixed inline (placeholders,
+  AC checkboxes, the description's task count).
+
+Gates this session: `cargo build`; server-less `cargo test
+--workspace` (core 28+3+1 doc, mem 102+26, sqlite 203+26, pg lib
+SKIP-posture 135+26+9, all green); the full pg column live vs the
+harness server (`pglo-poc` :15432 — 135 lib + 26 suite + 9 schema);
+`cargo clippy --all-targets -- -D warnings`; `cargo fmt --check`;
+the fuzz corpus replay (`fuzz/shared`, 6/6); the wasm32 mem check;
+the doc gate (`RUSTDOCFLAGS="-D warnings" cargo doc --no-deps`, zero
+warnings); `taskgraph validate` (96 tasks).
