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.

Description
chaotic HA soak still FAIL (committed_job_loss=8) after bug-1431 force-flush fix; jobs above the conservative 2-voter safe_committed_lsn floor stayed invisible via expect-job for ~3.1s post-promotion, matching the primary heartbeat interval (3000ms) almost exactly
Environment
Not recorded (migrated from buglog.json).
Reproduction
Not recorded (migrated from buglog.json).
Root cause
ha_start_primary_heartbeat armed the periodic heartbeat via delay_task_ms(interval_ms, -1, primary_heartbeat_fn, c), whose FIRST invocation fires only after interval_ms elapses (standard periodic-timer semantics) -- despite the functions own long-standing comment claiming to start the heartbeat immediately. A freshly-promoted leader therefore waited a full heartbeat interval before ever sending a NOP to a reconnecting/catching-up standby, so it could not learn that standbys true applied_lsn (via the heartbeat-reply stateReport, ha_process_standby_state) for up to 3s. That knowledge gates when catch-up WAL streaming starts and, in turn, the per-entry majority-ack that advances committed_lsn past the elections conservative safe_committed_lsn floor (jobs above that floor were legitimately majority-committed via the OLD primary before it died, per Leader Completeness, but the new leader cannot expose them without fresh quorum corroboration -- a correct Raft Figure-8 safety requirement, not a bug in itself).
Fix
ha_start_primary_heartbeat now calls primary_heartbeat_fn(c) synchronously once, immediately, before arming the periodic delay_task_ms timer -- matching the functions own documented intent. primary_heartbeat_fn only performs non-blocking async sends (xce_ha_heartbeat_req), so this is safe inline with no thread-role change. Single fix point covers all 3 promotion call sites (raft_cb_become_leader, ha_promote_to_primary, and the third raft-driven-decision-loop site) since all route through ha_start_primary_heartbeat. Closed the gap: 10-round chaotic soak went from committed_job_loss=8 to committed_job_loss=0, committed_divergence=0, result=PASS; 10-round sequential soak + leadership-coverage also PASS (36 jobs, zero loss).
Verification
Not recorded (migrated from buglog.json).
