Track: adopt agentic-qe 3.12.3 (atomic RVF export + self-heal) and remove the corrupt-lock guard

[pacphi]

What we're waiting on

Upstream agentic-qe PR #564 (release v3.12.3) fixes the RVF corruption we filed as #563: non-atomic brain.rvf export → truncated store + permanent FsyncFailed, silently dropping aqe off ruvector.

Status at time of filing (2026-07-17): PR #564 is open / not merged; agentic-qe@3.12.3 is not published (latest on npm is 3.12.2). Nothing to do until it ships.

What 3.12.3 changes for us

• Exports become atomic (tmp + rename) — the corruption stops happening.
• Genuinely-unusable stores self-heal on the next run, non-destructively (quarantine-aside, not delete), gated on the lock's owner pid.
• The kit's own corrupt-lock detector is unsound and becomes redundant: FLVR is the normal lock magic (store magic is SFVR), a 162-byte store is a valid empty store — measured against @ruvector/rvf-node 0.1.8 and confirmed across every lock on the dev machine. See PR fix(rvf): version-gate + pid-guard the corrupt-lock detector (retires on aqe 3.12.3) #31 (fix/rvf-corrupt-lock-detector-version-gated).

Already shipped (PR #31, merged/pending)

• aqeSelfHealsRvf() gate: the corrupt-lock scan auto-retires once installed aqe ≥ 3.12.3 — so the moment we ak sync up to it, the kit stops second-guessing aqe. No code change strictly required at release time; it flips on version detection.
• Interim safety on < 3.12.3: the legacy scan is now pid-guarded (only a stale/dead-owner lock can trip it — never a live peer's store).

Acceptance criteria (do these when 3.12.3 lands)

• npm view agentic-qe@3.12.3 version returns 3.12.3 (published)
• PR #564 shows merged
• ak sync bumps the machine to aqe 3.12.3; confirm ak status no longer shows an aqe … stale/oversized RVF row on a previously-flagged project
• Confirm aqe self-heal fires (its [RVF] Quarantined unusable store … / Removed stale lock … log on a real broken store), i.e. the kit's guard is genuinely dead weight
• Then delete the now-dead corrupt-lock branch + aqeSelfHealsRvf gate from src/lib/rvf.mjs (keep only the oversized backstop), and simplify the aqe status/heal wording
• Update memory note aqe-brain-rvf-fsync-issue

How we'll get notified

Watching for the release rather than polling by hand — see the follow-up in this thread (scheduled npm/GitHub-release check). Manual check any time:

npm view agentic-qe@3.12.3 version   # empty until published
gh pr view 564 --repo proffesor-for-testing/agentic-qe --json state,merged

Refs: aqe #563 (root cause), aqe #564 (fix), kit PR #31 (interim guard + gate).

RELEASE-WATCH: agentic-qe 3.12.3 detected

agentic-qe 3.12.3 is now published on npm; upstream PR #564 (atomic RVF export + self-heal for #563) has shipped.

Reminder of the adoption checklist for this issue:

• Run ak sync to bump to aqe 3.12.3
• Confirm ak status no longer shows an aqe … stale/oversized RVF row
• Confirm aqe's own self-heal fires on a real broken store
• Delete the now-dead corrupt-lock branch + aqeSelfHealsRvf gate from src/lib/rvf.mjs (shipped in PR fix(rvf): version-gate + pid-guard the corrupt-lock detector (retires on aqe 3.12.3) #31)
• Update the aqe-brain-rvf-fsync-issue memory

Close-out: all acceptance criteria satisfied

Verified live today (2026-07-20):

• npm view agentic-qe@3.12.3 version → 3.12.3 (published, and 3.13.0 is now latest)
• Upstream PR chore(release): v3.12.3 — atomic RVF export + self-healing stores (#563) proffesor-for-testing/agentic-qe#564 shows MERGED (2026-07-17)
• ak sync's upgrade path (npm install -g agentic-qe@latest) has already bumped this machine to agentic-qe@3.13.0; ak status on this repo reads "RVF store healthy" with no stale/corrupt-lock row
• The self-heal gate fired as designed: PR fix(rvf): version-gate + pid-guard the corrupt-lock detector (retires on aqe 3.12.3) #31 (merged 2026-07-18) shipped the version-gated aqeSelfHealsRvf() guard that retires the kit's own scan once aqe ≥ 3.12.3 is installed
• Delete the dead corrupt-lock branch + gate; simplify wording — already done, out-of-band from this issue, in commit 5a082b0 (PR feat: sync UX + statusline/RVF root-cause fixes, full-codebase hardening, docs audit #35, merged 2026-07-18). src/lib/rvf.mjs now only contains the oversized-store backstop (scanRvf/quarantine); tests/kit/rvf.test.mjs was rewritten alongside it with no leftover corrupt-lock/pid-guard coverage. Grepped the full codebase today — no corrupt-lock/stale-lock language remains anywhere (status.mjs, heal.mjs, x/verify.mjs all already carry oversized-only wording).
• Memory note aqe-brain-rvf-fsync-issue updated to reflect resolution

PR #35's commit message doesn't reference this issue, so it never auto-closed despite shipping the fix — closing explicitly now. Thanks for the fix, upstream!
