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-1427: APPLY_DIVERGENT's entity-count correctness check (persist_verify_apply_correctness) covers job…
|
|
|
|
## Description
|
|
APPLY_DIVERGENT's entity-count correctness check (persist_verify_apply_correctness) covers job entities only — worker entities can diverge (worker_from_capnp()/restore_worker() genuinely creates a new worker on a WAL_WORKER_CTRL/HOOK_DETAIL_WORKER_JOIN entry when absent) but this is currently invisible to the check.
|
|
|
|
## Environment
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Reproduction
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Root cause
|
|
Disclosed, accepted scope gap from raft-apply-decoupling task 5.1's own design: the entity-count check was scoped to jobs only (queues correctly excluded — config-derived, WAL_QUEUE_CTRL never creates a new one, verified by two review rounds). Workers were never brought in scope. Not a regression — a known, deliberate boundary, just not yet extended.
|
|
|
|
## Fix
|
|
FIXED (TDD RED->GREEN). Extended persist_verify_apply_correctness() with a worker-count check mirroring the existing job-count check exactly: added count_workermgr_entries() (persist.c, mirrors count_jobmgr_entries()), a new expected_new_worker_count field on apply_expectation_t (persist.h), and a new workermgr_count_before_replay parameter threaded through persist_verify_apply_correctness()/persist_recover(). The harder part: apply_committed_entry()'s WAL_WORKER_CTRL case previously always returned 0 regardless of outcome (JOIN-creates-new, UPDATE-applies-to-existing, and idempotent-noop were all indistinguishable to callers), so replay_wal() had no signal to tally new worker joins from. Fixed by making worker_from_capnp() (worker.c) return 1 specifically for a genuine new-worker creation (discarding restore_worker()'s raw idx, which can legitimately be 0 and would have collided with the update-applied case) and propagating that rc through apply_committed_entry() instead of the hardcoded 0 -- verified no caller of either function depended on the exact prior return value (only sign and -EEXIST were ever checked). replay_wal() tallies apply_rc==1 for WAL_WORKER_CTRL exactly like it already does for WAL_JOB_SUBMIT. New regression tests: test_verify_apply_correctness_detects_worker_count_mismatch (test_apply_correctness_verification.c, mirrors the existing job-count-mismatch test) proves a worker-count divergence is now caught as APPLY_DIVERGENT -- RED before this fix (no worker check existed at all), GREEN after. Also updated test_apply_committed_entry.c's test_ace_worker_ctrl_join_restores_and_notifies, which asserted rc==0 for a genuine JOIN creation under the old (now-corrected) contract -- now asserts rc==1 with an explanatory message. Full controller_unit_test suite: 1097 tests, 2 pre-existing unrelated failures (bug-1561), no regressions.

[Original entry]
|
|
NOT FIXED. Extend persist_verify_apply_correctness() with a worker-count check mirroring count_jobmgr_entries() if/when a worker-creation divergence needs to be closed (task 5.1's own forward note).
