feat(buglog): one Markdown record per bug, checked against a record standard
The buglog was one 27K-line JSON file whose fields covered only symptom,
root cause and fix, as free text: 2% of entries named the code version a
bug was found on, 12% the build profile, 36% a way to reproduce, and 58% of
the file was OpenWolf hook auto-detections ("Missing guard clause",
"Function not marked async" on .md files).

- .claude/skills/buglog/bug-record.md: the record standard. Eight
  sections (Summary as the title, Description, Environment, Reproduction;
  Root cause, Fix, Verification, References once fixed), each with the
  content it must contain -- e.g. Environment needs the OS, the libc the
  failing binary loads (from its ELF interpreter: glibc 2.42 in the nix
  shell vs 2.40 on the host), toolchain, build profile and commit.
- .wolf/bugs/<id>.md: 500 records migrated from buglog.json; every field
  verified to round-trip. They carry legacy: true and an explicit "not
  recorded" where the old log had no such field; component derived from
  file paths, severity from keywords (else unknown), fix_commits from
  hashes in status_note/fix that git resolves (91 of 463 fixed).
- .wolf/buglog-archive.json: the 710 hook auto-detections, verbatim.
- .wolf/buglog.json is now an index generated from the records, keeping
  the fields OpenWolf's hooks and `openwolf bug search` read.
- scripts/buglog.py rewritten: new (template + Environment collected from
  the machine and --binary), check, status (refuses a status the record
  doesn't support; fixed needs Root cause, Fix, Verification and
  --commit hashes git resolves), note, recur, set, show, list, triage,
  env, index. 29 unittest cases in scripts/tests/test_buglog.py.
- scripts/git-hooks/pre-commit runs `check --staged`: incomplete staged
  records, a legacy record hand-changed to fixed without the fix-time
  sections, a new record claiming legacy: true, or a stale index refuse
  the commit.
- scripts/gitea-sync.py reads the records: issue body = the record's
  sections plus linked fix commits (origin remote, GITEA_COMMIT_REPO to
  override), and a body hash so an issue's text is refreshed when the
  record changes.
- bug-1866 rewritten to the full standard as the worked example.

bug-447: queue_ctrl/worker_ctrl append NO WAL entry and reply status 1 on success; job_ctrl also returns 1…

Description

queue_ctrl/worker_ctrl append NO WAL entry and reply status 1 on success; job_ctrl also returns 1 (key_find found-rc leak)

Environment

Not recorded (migrated from buglog.json).

Reproduction

Not recorded (migrated from buglog.json).

Root cause

key_find (xkvmgr_find, lib/kvmgr.c:130-151) returns 1 when the key is found. queue_ctrl (queue.c:60), worker_ctrl (worker.c:643) and job_ctrl (job.c:314) store it in rc and never reset it: the 'if (rc == 0)' AFTER_EVENT hook gate is skipped (no WAL_QUEUE_CTRL / WAL_WORKER_CTRL append on the found path) and the requester reply carries status 1 instead of 0. Production gap discovered by task-3.1 RED tests; queue/host control state changes are currently never persisted or replicated.

Fix

FIXED (task 3.2, 2026-06-12): normalized the key_find found-rc to 0 in queue_ctrl (queue.c), worker_ctrl (worker.c) and job_ctrl (job.c) after the miss/-ENOENT checks, so the AFTER_EVENT hook gate fires (WAL append + replication) and the handlers' commit-barrier pattern sees 0. Handlers do_jobcontrol_op/do_queuecontrol_op/do_hostcontrol_op now run persist_commit_barrier(&c->persist, 0) on rc==0 before replying; handle_worker_join barriers between AFTER_EVENT and the success reply. All 12 test_commit_barrier_reply tests PASS; full controller suite 0 FAIL.

Verification

Not recorded (migrated from buglog.json).
