feat(buglog): one Markdown record per bug, checked against a record standard
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-1784: Discovered while live-verifying gitea#46's Part 1 (dispatch-stops-at-8, previously hypothesized in…

Description

Discovered while live-verifying gitea#46's Part 1 (dispatch-stops-at-8, previously hypothesized in bug-1743 to be limits.yaml's ug1_normal_slots cap=8 working as designed, never live-confirmed). Live test: submitted 10 single-slot jobs as user1 (a genuine ug1 member per users.yaml) on queue normal against a 22-slot worker -- all 10 ran, the supposed cap=8 usergroup limit never blocked anything.

Environment

Not recorded (migrated from buglog.json).

Reproduction

Not recorded (migrated from buglog.json).

Root cause

Named usergroups/hostgroups (users.yaml's top-level "usergroups:", hosts.yaml's "hostgroups:") are carried down to the scheduler via xce_conf4sched_t.ugroups/hgroups (src/controller/sched.c populates these from c->myconf->cluster_config->ugroups/hgroups), but nothing on the scheduler side ever registered them into a group manager by name: groupmgr_add() (src/lib/group.c) -- the obvious candidate -- had ZERO callers anywhere in production code (confirmed via full-tree grep). When a limit's own per-limit consumer group (plugins/limit.c's build_consumer()) references a named group like "ug1" as a member, make_g_member() (group.c) calls get_group(mgr, "ug1"), finds nothing (since it was never registered), and falls back to treating "ug1" as a literal, ungrouped member name that will never strcmp-match a real username via is_in_group(). Confirmed via source inspection (build_group(), a plausible alternative entry point declared in group.h, has NO implementation anywhere either -- a second dead prototype) and via live behavior (user1, a real ug1 member, ran unthrottled against a configured cap).

Fix

FIXED (2026-09-07). Added groupmgr_load_configs(var mgr, int count, xce_group_config_t** configs) to group.c/group.h: iterates the config list and registers each named entry into mgr via the existing, already-correct makeGroup(mgr, config, config->name). Wired into scheduler.c's sched_init_config(): groupmgr_load_configs() for both core.ugmgr/config->ugroups and core.hgmgr/config->hgroups, called BEFORE plugin_config_update() so any limit's own build_consumer() call (which runs inside plugin_config_update -> limit_update_config -> build_limit) can resolve a named-group reference at build time. TDD: 3 new tests in src/lib/testsuite/test_group.c -- test_load_configs_registers_each_group_by_name, test_load_configs_enables_group_name_as_member_reference (the exact regression: a limit-style unnamed consumer group referencing a named group by member, mirroring build_consumer()'s own call shape), test_load_configs_zero_count_is_a_noop. All pass (313 Tests 0 Failures under CGO... err, under ASAN_OPTIONS=detect_leaks=0 xcelib_test). Full scheduler suite: 76/77 (pre-existing unrelated bug-1762 test_core_events.c failure). LIVE-VERIFIED: fresh single-node deploy, user1 (ug1 member) submitting jobs on queue normal now correctly has match_limit() report a match (previously always rc=0/no-match) for ug1_slots and ug1_normal_slots -- confirmed via scheduler trace logs. (Full cap enforcement required two further fixes in the same session -- see bug-1786/1788 -- and one remaining gap not yet fixed, see bug-1789.)

Verification

Not recorded (migrated from buglog.json).
