v0.42.51.0 fix(sync): contention-free clock + checkpoint integrity + honest sync freshness (#2255)

* fix(sync): contention-free page-generation clock — sequence swap

The page-generation clock backed the query-cache Layer-1 bookmark via a
FOR EACH STATEMENT trigger running `UPDATE page_generation_clock SET
value=value+1 WHERE id=1`. That took a transaction-length RowExclusiveLock
on one tuple, so every concurrent page writer serialized on the prior
writer's COMMIT — sync ran at ~0.8 cores regardless of worker count.

Swap to a SEQUENCE bumped by nextval() (a microsecond LWLock, never a row
lock). The clock's only contract is monotonic advancement on any page
INSERT/UPDATE/DELETE; last_value is non-transactional, so rolled-back or
concurrent-uncommitted writers only OVER-invalidate the cache (lose a hit),
never serve stale.

- migration v118: CREATE SEQUENCE + load-bearing 2-arg setval (is_called=
  true, floor 1, seeded >= old clock and MAX(generation)) + repoint the
  trigger function body + DELETE query_cache so no old-clock bookmark
  survives the swap. v107 left immutable.
- query-cache-gate.ts: 3 readers -> SELECT last_value FROM page_generation_clock_seq.
- schema.sql + pglite-schema.ts (+ regenerated schema-embedded.ts) ship the
  sequence on fresh install; table + trigger names retained.
- tests: clockValue reads last_value; mechanism proof (trigger fn uses
  nextval not the row UPDATE); rollback-advances-clock safety pin; real
  PGLite sequence round-trip (is_called gotcha); shape test requires _seq.

* fix(sync): op_checkpoints array-shape guard — CHECK + repair + defensive loader

completed_keys is JSONB and the checkpoint loader runs
jsonb_array_elements_text over it. A non-array (scalar) value makes that
throw "cannot extract elements from a scalar", which takes down the whole
UNION load — including the valid op_checkpoint_paths child rows — and loses
all checkpoint progress for that key. No current writer produces a scalar,
but an older binary / external script / future bug could.

Make the corruption class structurally impossible and self-healing:

- migration v119: LOCK TABLE (so an out-of-band scalar can't land between
  repair and constrain; no-op on single-connection PGLite), repair any
  pre-existing scalar to '[]' (op_checkpoint_paths child rows are the
  append-only source of truth, so the reset loses nothing), then add the
  named CHECK (jsonb_typeof(completed_keys) = 'array') via a pg_constraint
  IF NOT EXISTS guard. A DB-enforced always-on guard — the correct pattern
  vs a migration verify-hook, which never runs on already-stamped brains.
- schema.sql + pglite-schema.ts (+ regenerated schema-embedded.ts) ship the
  same NAMED inline CHECK so fresh installs match migrated brains and v119
  skips the duplicate.
- op-checkpoint.ts loader: gate the legacy arm on jsonb_typeof = 'array' so
  a scalar parent is skipped (children still load) instead of throwing the
  whole union, and log a specific corruption warning when one is seen.
- tests: CHECK rejects a scalar (exactly one constraint, no blob+migration
  dupe); loader survives a scalar parent and returns the children; v119
  repair converts a scalar to '[]'.

* fix(doctor): report actively-running sync via live lock, not stale freshness

A slow source that makes partial progress every cycle but never fully
completes used to read as permanently "stale" / "never synced" because
last_sync_at only advances on a full successful sync. The naive fix
(treat recent checkpoint banking as "in progress") is unsafe: a blocked
sync banks the good files then writes no anchor, so banking can't tell
in-progress from wedged.

Use the only honest signal: a LIVE, non-expired per-source sync lock
(inspectLock + syncLockId against gbrain_cycle_locks). Every non-skipLock
sync holds it and refreshes it; a blocked/failed sync's process has exited
(no lock row) and a wedged holder stops refreshing (TTL lapses), so either
correctly falls through to the stale path and is NEVER masked. An
actively-syncing source (including a never-synced source doing its first
sync) counts as synced_recently, preserving the pinned 3-bucket invariant.
The lock lookup reuses doctor's existing dynamic db-lock import and swallows
any throw (stub engine, pre-lock-table brain) to false, so it can only ADD
an in-progress verdict, never suppress a real stale one.

Tests (real PGLiteEngine + real lock rows): stale+no-lock -> fail;
stale+live-lock -> ok; never-synced+live-lock -> ok; never-synced+no-lock
-> fail; expired-TTL lock -> fail (wedged not masked); blocked source with
banked checkpoint rows but no lock -> still fail.

* fix(sync): honest --force-break-lock diagnostic when no lock is held

--force-break-lock used to emit the same terse "Lock ... is not held
(nothing to break)" line and exit 0 even when a sync was genuinely wedged,
sending the operator down a dead end — the wedge was not a held lock. Keep
rc=0 (breaking a non-existent lock is idempotently successful; flipping the
exit code would break automation), but under --force say plainly that
nothing was broken and point at the real next step (gbrain sync / gbrain
doctor) plus a `wedge_hint` field in --json output. The non-force path is
byte-for-byte unchanged.

runBreakLock is exported for the test. Tests: force+no-lock -> wedge_hint
JSON + human hint, rc 0; non-force+no-lock -> unchanged terse line, no hint.

* fix(doctor): surface the in-progress sync holder in the freshness message

Plan-completion follow-up to the BUG 4 live-lock signal: when a source is
actively syncing, name the holder (pid + host) in the check message instead
of silently folding it into synced_recently. The note is appended only when
something is in progress, so steady-state messages stay byte-for-byte
unchanged (the pinned exact-message + 3-bucket-invariant tests still pass).

* fix(sync): pre-landing review fixes — monotonic clock seed, scoped CHECK guard

Adversarial (codex) review of the implementation diff caught three:

- P1 (correctness): the fresh-schema setval was not monotonic. initSchema
  replays the schema blob, and the unconditional setval(MAX(generation))
  could move page_generation_clock_seq.last_value BACKWARD on an
  already-upgraded brain, letting a stored query_cache bookmark serve stale
  rows. Seed via GREATEST over the sequence's OWN last_value (+ old table
  value + MAX(generation)) in all 3 fresh schemas and migration v118, so a
  replay is idempotent — mirrors the old table's ON CONFLICT DO NOTHING.
  Pinned by a new monotonic regression test.
- P2: v119's CHECK-exists guard keyed on conname only (not globally unique).
  Scope it to conrelid = 'op_checkpoints'::regclass.
- P3: in-progress note ran into the prior sentence in fail/warn doctor
  messages; separate it with '. '.

* test: make Anthropic/ZE no-key tests hermetic against a dev config key

These "no key" tests cleared only ANTHROPIC_API_KEY / ZEROENTROPY_API_KEY
from the env, but hasAnthropicKey() and checkZeEmbeddingHealth() also read
the key from ~/.gbrain/config.json. On a dev machine whose real config holds
a key, the no-key assertions flipped and the tests failed locally (they
passed only in key-less CI). Add a shared with-env emptyHome() helper and
point GBRAIN_HOME at an empty dir in every no-key path so loadConfig finds
nothing — matching the already-hermetic anthropic-key / gateway-probe tests.

* chore: bump version and changelog (v0.44.1.0)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs(key-files): sync doctor + op-checkpoint entries to v0.44.1.0 truth

checkSyncFreshness now reports an actively-running sync via the live
per-source lock (names holder pid+host, counts as synced_recently) instead
of flagging it stale; loadOpCheckpoint gates the legacy union arm on
jsonb_typeof = 'array' so a scalar parent can't take down the whole load,
and migration v119's CHECK constraint makes the corruption class
structurally impossible. Reference docs describe current behavior only —
both entries updated in place, no release-clause appends. Guard + llms
freshness test green.

* chore: re-version to v0.42.51.0 (natural next-off-master)

Maintainer override of the queue allocator's leap to 0.44.1.0 (it jumped past
in-flight sibling PR claims at 0.42.50/0.43.0/0.44.0). Take the natural next
slot in the 0.42.x line above the immediate sibling claim (0.42.50.0); a
merge re-bump resolves any collision if a cathedral PR lands first.

* ci(e2e): bound + retry the OpenClaw install so a transient npm hang can't burn the Tier 2 budget

The Tier 2 (LLM Skills) job failed at 30m16s — the `npm install -g
openclaw@2026.4.9` step hung on a transient npm/registry stall (orphan
`npm install openclaw` was still running at cancel time) and consumed the
entire 30m job budget that v0.42.50.0 (#2254) introduced. The install
normally finishes in under a minute (Tier 2 is ~4m end to end on master),
so this is flaky-install infra, not a test failure.

Wrap the install in `timeout 120` + a 3-attempt retry loop with an 8-minute
step backstop: a hung attempt is killed in 2 min and retried instead of
eating the whole job. Same bound-the-hang philosophy as #2254's job timeouts.

## [0.42.51.0] - 2026-06-17
**`gbrain sync` stops bottlenecking all its workers on a single database row, a malformed checkpoint can no longer wedge a source, and `gbrain doctor` tells an actively-running sync apart from a stuck one.** A slow source that fell behind HEAD could read as permanently stale even while it imported every cycle: sync was single-core-bound at the database layer, so handing it more workers didn't help, and the freshness check couldn't see that a sync was in fact running.
The root cause was the page-generation clock that backs the search cache. Every page write bumped a single locked counter row, so concurrent sync workers serialized on one another's commits no matter how many you ran. It is now a contention-free sequence: the cache invalidation contract is unchanged (it still over-invalidates rather than ever serving stale), but writers no longer wait in line. The other fixes harden checkpoint state and make the freshness signal honest.
### Changed
- **Sync writes scale across cores.** The page-generation clock moved from a single locked counter row to a contention-free sequence, so parallel sync workers stop serializing on each other. A large `gbrain sync` now uses the workers you give it instead of collapsing to roughly one.
- **`gbrain doctor` distinguishes in-progress from stale.** A source holding a live sync lock is reported as actively syncing (naming the running process), not flagged stale. A genuinely stuck, blocked, or never-completed sync still reports stale — the signal is the live lock, so a stopped sync is never masked.
### Fixed
- **A malformed checkpoint record can no longer wedge a source.** Checkpoint state is structurally constrained, repaired automatically on upgrade, and the loader survives a bad record instead of discarding all banked progress for that source.
- **`gbrain sync --force-break-lock` is honest when there is no lock.** It now says plainly that nothing was held and points at how to inspect a genuinely wedged sync, instead of a terse no-op that read like a successful unwedge.
### To take advantage of v0.42.51.0
`gbrain upgrade`, then `gbrain doctor`. Existing brains pick up the contention-free clock and the checkpoint integrity constraint automatically on the next migration; the search cache rebuilds itself on first query. Nothing to configure.
## [0.42.50.0] - 2026-06-17
**CI reliability hardening — a wedged job can no longer run for six hours, a superseded run no longer reports a stale flaky failure, and broken workflow YAML is caught before it ships.** gbrain's CI already had the deep machinery (content-hash run-skip cache, weight-aware shard balancing, test-isolation guards, hermetic E2E). What it lacked was the cheap GitHub-Actions hygiene that was already wired into `heavy-tests.yml` but never into the two hot-path workflows. This pass closes that gap, porting the patterns from the sibling GStack project's CI-reliability work.
