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-1446: /kiro-validate-impl ha-commit-durability: test-commit-durability.sh --deterministic reported 3/3…
|
|
|
|
## Description
|
|
/kiro-validate-impl ha-commit-durability: test-commit-durability.sh --deterministic reported 3/3 FAIL ('DURABILITY GAP -- primary acked with 0 fdatasync in-window'), i.e. a false RED that looked like a regression of the spec's core invariant on the current build.
|
|
|
|
## Environment
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Reproduction
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Root cause
|
|
This sandbox's /sbin/date is BusyBox date, which does NOT support GNU date's %N (nanoseconds) format directive -- 'date +%H:%M:%S.%N' literally emits the unexpanded string 'HH:MM:SS.%N' (confirmed by direct invocation). det_probe_once() captures t0/t1 with this call to bound the submit-to-ack window, then _hms_to_sod() converts them to seconds-of-day for the in-window fdatasync count. With the literal '%N' suffix the sub-second component is unparseable/degenerate, so the computed window fails to contain the real fdatasync timestamp even though it lands in the same wall-clock second -- producing syncs=0 (RED) regardless of actual ordering. This is an environment tooling gap (BusyBox vs GNU date), not a code regression: the script assumes GNU date is on PATH.

## Fix
|
|
NOT a product bug, no source fix applied (out of this validation's scope; script is owned by xce-test-e2e-primitives per this spec's task 1.3 boundary note). Diagnosed by cross-checking strace's own microsecond timestamps (which DO work correctly, e.g. 'fdatasync(10) = 0' at 00:47:01.128244) against the controller's committed_lsn advance log lines (commit_advance_locked '1 -> 2' at 00:47:01,144) for the same three probes: fdatasync consistently preceded the commit-advance (that gates the client ack) by 16-43ms in all 3 probes -- i.e. the real durable-before-ack ordering the spec requires DOES hold on the current build; the script's verdict was the false signal, not the product. Recommend the script detect/require GNU date (or use 1784335901.164264 / a C helper) rather than assuming %N support, so it fails loud on an incompatible date instead of silently producing a false RED.
