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-1496: xce_sched_core_load_snapshot() never restored core->prng_seed from the snapshot -- a freshly…
|
|
|
|
## Description
|
|
xce_sched_core_load_snapshot() never restored core->prng_seed from the snapshot -- a freshly loaded core silently kept xce_sched_core_init()'s default (0) instead of the value xce_sched_core_save_snapshot() had captured. Caught by test_snapshot_save_load.c's field-level assertion: TEST_ASSERT_EQUAL_UINT64(0xDEADBEEFULL, core_b.prng_seed) failed with Expected 3735928559 Was 0 after a successful save+load round trip.
|
|
|
|
## Environment
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Reproduction
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Root cause
|
|
save_snapshot() (snapshot.c) correctly writes `out->prng_seed = core->prng_seed;`, but the corresponding `core->prng_seed = in->prng_seed;` assignment was simply missing from load_snapshot()'s field-copy sequence -- an incomplete round trip for a field the function's own header comment (snapshot.c, 'PRNG seed resolution') explicitly documents as in scope (Req 5 AC 21's 'PRNG state' checklist row).
|
|
|
|
## Fix
|
|
Added `core->prng_seed = in->prng_seed;` to xce_sched_core_load_snapshot() (snapshot_load.c), placed after the jobs-restoration loop and before the internal_state restoration block. Verified via the same field-level assertion, now passing.
