- sqlite scheduler tick: a failed COMMIT (or ROLLBACK) left the connection
released with a stuck-open transaction, wedging the writer slot forever —
the one commit site missing the drop-+-reopen-replenish arm; tick now
takes the conn by value with a poisoned disposition (drop + replenish),
the commit-fault seam reaches the tick, and
failed_tick_commit_replenishes_the_writer_slot pins the arm
- pg save_offset_tx stored GREATEST($3,0) where the wave-8 gate's
negative-seed fix (raw seed, ADR-023 §2 2026-10-11 annotation) covered
only the auto-commit form; mem's merged in-tx read clamped a staged
negative seed against a phantom zero; both fixed and the tx-form
totality pinned by a new stamped suite leg (in_tx_reads_see_own_writes)
green on all three columns vs the live harness server
- pg: a failed forwarder register leaked the channel refcount forever
(no receiver to drop it) — listen/spawn_bridge now unregister on the
register error, mirroring the subscribe-failure arm; register doc
corrected to put the failure disposition at the call site
- pg forwarder: nine poisoned-mutex expect() panics converted to the
mem crate's into_inner recovery idiom (no-expect-outside-tests rule)
- core encode_payload: a deeply-nested Value aborted the process in
serde_json's unguarded serializer recursion and the fuzz pin blessed
storing bytes no decoder could read back; encode now rejects nesting
past 127 containers (the empirically-verified decode limit) with typed
Codec — decode-aligned boundary pins added to the fuzz invariant and
value_type_tests, applied pre-publish within the open class-1 window
- scheduler sleep deadlines: Instant + Duration overflow caps (MAX_SLEEP_S,
tick-and-resleep) on all three engines for far-future boundaries;
sqlite tick claim stamp now saturating_add
- docs read true again: Error::Closed scope (stream try_recv arm),
validation whitespace wording, sqlite lib.rs phantom durability knobs,
pg lock.rs honest autocommit wording, mem tx/stream merge + wake-
granularity wording; wakes.rs stale allow(dead_code) removed
- tests: value_type_tests exercised its own map_err instead of the
function under test (fixed); unwrap_or_default reference encodes
panic with cause
- docs/reviews/004-pre-release-general-review.md records nine fixed +
sixteen parked findings (sqlite seam panic-safety armor, watcher
post-death-subscribe hang + initial-stat self-kill, pg forwarder
TOCTOU/hang/diagnosability, pg BIGINT server-side stamp overflow, mem
growth/outbox notes, pg identifier-truncation doc note, smaller) and
two false positives caught on verification; implementation.md
review-rounds entry + core-contract backlog rows updated
- gates: build, workspace tests (sqlite 194, core 27, suite legs new),
full live pg column 127+25+9, clippy -D warnings, fmt, fuzz replay
6/6, wasm32 check, doc gate -D warnings — all green
The wave-8 N-1 deferred item — re-read the three unconditional-growth
paths against the implemented engines and land the decision of record:
all three accepted for v1, per engine, with no engine-side hygiene.
- deployment.md: new 'Growth postures (consciously accepted)' section —
per-engine table (dead letters sweep-on-call, SQLite-only notify
at-attach cap, durable-log stream posture; mem process-lifetime-
bounded by design) + the rationale and the deployment-matrix
fold-in positioning.
- engine-sqlite.md: 'Notifications-table hygiene' — attach is the only
prune site (D-16, oldest-first 10k); idle-but-listening processes
never prune; the cadence caveat deployers should size for.
- tasks/release-n1-growth-posture.md: completed; Notes/Summary filled.
The born-pinned gate audited the mem engine against the contract and
ADR-024: the conformance read clean in mechanism substance (queue
state machine, scheduler collapse, outbox, streams, locks, clock,
validation, tx overlay, wake substrate — incl. a full guard-order and
panic-hygiene audit); the suite's third column read row-by-row and
25/25 green under the per-test current-thread flavor (24 engine-shared
rows + mem's payload_too_large non-occurrence arm + the factory-shape
test); three-way arithmetic equivalence green on all columns; the
wasm32 acceptance items verified (compile-clean, tokio sync+time,
no blocking, flavor enforced); the rider's two arms verified (Finding
1 discharged; Findings 2-3 stay parked for wave 7); workspace gates,
taskgraph validate green.
Three edge-domain fixes landed inline: the stream cursor read's
i64::MAX overflow (Bound::Excluded), trim_to's i64::MAX horizon
endpoint (Bound::Included), and the scheduler register path now
rejecting a parseable interval whose first boundary overflows with
InvalidSpec — the one engine-vs-engine divergence the read found,
aligned into the class-1 window — plus a pinning test and scaffold-
residue doc/comment cleanups (clock allows, tx per-stream wake
comment, wakes/stream module docs). Recorded findings with
dispositions in the task's Notes for the wave-7 pre-release pass:
the multi-thread publish-to-wake ordering tolerance, the heartbeat/
save_offset/EventReceiver-try_recv ADR-023 §2 classification gaps,
and the mem arithmetic being a suite-pinned transplant.
Verified: cargo build; cargo test --workspace green (mem 101 lib +
25 suite, sqlite 191+25, pg 124+25+9 server-less, core 25, harness 3);
clippy --all-targets -D warnings clean; fmt clean; taskgraph validate
(61 tasks). Gate record: tasks/review-wave-6.md (Notes + Summary),
implementation.md wave-6 row + review-rounds entry.
Row-first gate: consumer-inventory.md gains an engine-tier section — the mem-engine need recorded operator-authority, dated 2026-10-10 (wasm32 sandboxing across the alk protocol family + downstream ffi/napi/python-adapter economics; rusqlite/tokio-postgres structurally out on wasm, so mem is the only triad member the sandbox can carry).
ADR-024 (decisions/024-mem-engine.md) pins the decision set: (1) separate `alkstore-mem` crate — discharges and amends ADR-001 §4 (superseded in part: full contract-v1 engine, not an "implementation convenience"; annotation on ADR-001 §4 + Status, class-1 window still open); (2) honest-ephemeral posture — no durability, single-process, ephemeral by design, never fleet-valid (ADR-010 §3's shared-pool predicate fails structurally), riding ADR-016's carriers unchanged (identity + docs + matrix); (3) full contract v1 tier with the asymmetry classification — `PayloadTooLarge` never produced (SQLite arm), no reconnection concept (reconnect-wake/watcher rows absent from mem's per-engine column), receiver close at engine drop, wake coalescing N/A; (4) `MemStore::new()` engine-native constructor — the one documented exception to the open-prose, core-contract.md Store concept amended; shared-instance (two opens → one engine) rejected with the ADR-016 §4-style re-entry gate (consumer-inventory row), register stays closed; (5) wasm32 — compile-clean for wasm32-unknown-unknown plus the suite's mem column green on host under a current-thread runtime flavor are wave-6 acceptance items; on-target suite execution scoped out with a named collapse condition (wasm-bindgen-test adapter crate) — a scope decision, not a pending-client hedge; (6) mem is not a core dev-dependency — core's doc examples stay mock-based, ADR-001 §4's doctest posture declines.
engine-mem.md (draft): the in-process mapping — guarded per-mechanism state (no pool, no schema bootstrap, no forwarder, no spawn_blocking seam), the tx overlay (staged *_tx effects merged atomically at commit; read-your-own-writes easy, drop-=-rollback trivial; wake-at-commit structural — the seam pg needed pg-fix-tx-wake for, mem pins from birth via the existing tx-commit-atomicity rows), ADR-012 §2 third owner of the curve/opts/@every arithmetic (three-way equivalence, ADR-022's StoreFactory reused verbatim — born pinned).
deployment.md: host-semantics row (single-process, ephemeral, never fleet-valid, wasm32-clean), mem connection-budget subsection (none — nothing to budget), durability-knobs row (the honest row is the absence), toolchain row (wasm32 subset + current-thread-clean, acceptance-cited). README/overview: engine-mem.md row, ADR-024 row, family table entry (alkstore-mem, no driver deps), current-state updated to the implementation phase with engine specs' stable statuses reflected.
implementation.md: wave table gains wave 6 (mem engine, depends waves 1 + 5) and renumbers release readiness to wave 7 (fuzzing decision — the one remaining decided-at-implementation deferral — rides wave 7); wave-6 section records the born-pinned posture, acceptance items, the one suite-harness pre-task (past_stamp_sleep blocking sleep → async sleep, review 003's properties.rs:1683 note), and the window riders (review 003 Finding 1: the pg transient-fault seam, MEDIUM, rides wave 6; Findings 2–3 follow their park into wave 7's pre-release); wave-6 review gate defined; Decided points updated (mem discharged, fuzzing renumbered); stale wave-6 references swept across review docs and the landed tasks' notes (release-readiness items renumbered or annotated).
Docs-only change; verified by cross-reference audit (all ADR/OQ/anchor references resolve, residual wave-6 mentions are correct under the new numbering or carry dated annotations).
- forwarder.rs's ListenerConnection doc corrected: NoTls is hardwired on
every connection path (pooled, listener, reconnect) — the pooled path
never rode the consumer's Config sslmode (a sslmode=require DSN fails
at connect); grep-audited no other in-crate doc repeats the claim
- PgOpts doc carries the corrected one-line TLS pointer (engine-crate-
docs posture, ADR-016 §2)
- deployment.md: new 'TLS posture (v1)' subsection (NoTls everywhere,
sslmode=require DSN fails at connect, topology-level confidentiality
is the v1 substitute, TLS a post-v1 deployment concern) and a new
'Consumer-obligation notes on engine options' section carrying the
QueueOpts trusted-as-given note with code-verified per-field symptoms
(max_attempts <= 0: never claimed, dead-lettered at the next claim
call's pre-claim sweep; negative visibility: instantly-reclaimable
claims; negative retention: every dead row at the next sweep_expired)
plus the PgOpts::max_size 0-guard counter-case; frontmatter advanced
- alkstore/src/opts.rs: QueueOpts struct doc mirrors the
consumer-obligation note (ADR-023 §2 scoping: the domain table covers
trait-surface arguments, not consumer-constructed constants)
- cross-file doc sweep over the fix batch's touched files (forwarder,
tx, scheduler, store) found no further doc-behavior mismatch
- gates: cargo build / clippy --all-targets -D warnings / fmt --check
all green (doc-only, no test touched)
Operator review of ADR-012's fork design re-litigated §1's crate
identity. alkstore-substrate misdescribed what the code is (unpublished,
path-dep-only, one consumer, SQLite-only — not a family-wide substrate);
the mechanical-diff hope was gone at fork time regardless (port deltas,
renames, re-derived half); and the alksocks F-1 lesson applies — a
vendored region under a second, weaker instruction set is a defect seam.
The fork folds into alkstore-sqlite as a bounded module subtree
(src/substrate/); ADR-012 §3–§6 retained verbatim, §2 retained with its
enforcement re-sited from the crate graph to diff fence + review +
contract-suite equivalence pins. OQ-11 item (1) dissolved.
Follow-through on OQ-06/ADR-011: pin the fork's structural decisions
(alkstore-substrate as a vendored path-dep crate, contract-blind API
boundary with contract formulas computed engine-side and pinned
equivalent by the contract suite, keep-the-kept-half API fidelity for
cheap cherry-picks, the W-1/W-2/dead-man's-switch/W-4 port deltas
decided per item, bootstrap re-keying off error-string matching, no
rename migration, deliberate upstream tracking).
Consistency sweep across the doc set for the fork: annotate ADR-003/
005/009/010 and core-contract for superseded ownership facts, fix
schedule-storage table naming (ADR-009 §5, queues.md), re-key ADR-010
§6's notifications hygiene to the at-attach cap the fork scope
realizes, add OQ-11 (scaffold-time residue), and complete both ADR
indexes. Independent review: 0 critical, warnings addressed.
Quality read of honker-core's watcher/transactional core cross-checked
against the published crates.io artifact: the core itself is clean
(Writer/Readers, polling-watcher failure handling, WatcherDeathGuard
all verified), but published 0.5.0 predates upstream's unreleased fix
train carrying the issue-#133 savepoint hardening (silent job loss in
the dead-letter paths) and five .ok() error swallows — and ADR-010's
queue depth requires engine-owned queue SQL in any posture. Resolution:
fork honker-core at the reference revision, inherit the clean machinery
and test suites, re-derive queue ops on contract v1, rename tables to
__alkstore_*.
