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-1454: Scheduler --peers correctly wired for initial controller discovery; minor issues: nmasters=1 (no…

## Description
|
|
Scheduler --peers correctly wired for initial controller discovery; minor issues: nmasters=1 (no EndpointRotator) and leaked ctx on HA path
|
|
|
|
## Environment
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Reproduction
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Root cause
|
|
VERIFICATION: --peers IS correctly parsed via xce_parse_peers() (main.c:129), stored via sched_set_cluster_cfg() (main.c:156), and iterated in sched_init() HA loop (scheduler.c:462-493) BEFORE sched_init — init ordering is correct. Narrowed findings: (1) nmasters=1 per attempt (line 468) — manual candidate loop instead of filling config->masters[] from all candidates so libxce EndpointRotator never engages. Functional but suboptimal. (2) Leaked apictx on HA path — xcecli_ctx_init at line 454 allocates sched->apictx, then HA loop at line 472 re-inits without xcecli_ctx_fini on the first allocation. On standby-failure branches (lines 480, 492) cleanup is correct. OUT OF SCOPE: runtime reconnect/rejoin after controller death belongs to .kiro/specs/component-failover-adoption/ (requirements + design approved, tasks 3.1/3.2 not yet approved).
|

|

## Fix
|
|
DONE (leak fix only). Fixed the confirmed defect: sched_init() called xcecli_ctx_init(&sched->apictx, config) unconditionally, then on the HA path re-called xcecli_ctx_init() inside the candidate loop without freeing the first ctx -> leaked one xcecli_ctx_t per sched_init() call. Fix: xcecli_ctx_fini(sched->apictx) added immediately before the HA loop starts (src/scheduler/src/scheduler.c), since the loop's first iteration always replaces it. Verified via full ASAN build: all 5 scheduler meson test suites + libxce suite pass, no regression. REJECTED the nmasters>1+EndpointRotator suggestion: memory obs 11825 (this session) confirms scheduler/worker deliberately use the candidates[]-loop path instead of filling config->masters[], so changing that would contradict the established design, not fix a bug. Runtime reconnect/rejoin gap remains out of scope, deferred to component-failover-adoption spec (unchanged from original triage).
