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-1448: /kiro-validate-impl ha-heartbeat-committed-propagation: the xce-build skill's own documented…
Description
/kiro-validate-impl ha-heartbeat-committed-propagation: the xce-build skill's own documented pattern ("dispatch via a plain Agent-tool call, run_in_background: false, wait for it") produced an INCOMPLETE build -- ninja log ends with 'ninja: build stopped: interrupted by user.' at 85/192 targets, roughly 14 minutes after launch with zero nix/meson/ninja processes still running and no error in the log. The synchronous Agent call returned to the caller almost immediately (~38s) with text claiming 'The build is running in the background... I'll wait for it to complete' -- i.e. the subagent itself spawned an internal Bash run_in_background job and then ended its own turn, rather than blocking until the command finished.
Environment

Root cause
Same defect family as the already-documented xce-test-ha/run-ha-soak.sh 'context: fork' SIGHUP-teardown bug (fixed 2026-07-08), but manifesting through a DIFFERENT mechanism: xce-build's skill doc explicitly avoids 'context: fork' and claims a plain Agent-tool dispatch is safe -- but that safety claim implicitly assumes the subagent's own Bash tool call blocks synchronously for the whole build. In practice the subagent chose to run the long nix/meson/ninja command via its OWN internal run_in_background Bash call and then finished its turn, un-detached (no setsid/nohup/disown) -- so when that subagent's session/turn ended, the still-attached background job's process group got interrupted (ninja saw SIGINT/SIGHUP-equivalent, logged literally as 'interrupted by user'). A second SendMessage asking the same agent to 'wait for it now' resumed a session with nothing left alive to wait for.
Fix
Relaunched the build via a fresh Agent dispatch whose ONLY instruction was to run setsid nohup nix develop ./src --command bash src/tools/xce-build.sh controller asan </dev/null >LOG 2>&1 & disown and return immediately (fire-and-forget), then polled LOG/binary-mtimes independently from the main session via the Monitor tool. That build completed cleanly in ~10 minutes (85/85 ninja targets, clean link, meson test suite started normally) with no interruption. General fix for any long shell command dispatched through the Agent tool that must outlive the dispatching subagent's own turn: always explicit setsid+nohup+disown, never rely on the subagent's internal run_in_background alone or on run_in_background:false at the Agent-tool-call level to guarantee synchronous blocking all the way through.
Verification
Not recorded (migrated from buglog.json).
