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-1821: User-reported: xceadmin's --controller option (config push and all 3 scheduler record…

Description

User-reported: xceadmin's --controller option (config push and all 3 scheduler record start/stop/status commands) accepted only a SINGLE host:port -- passing a comma-separated list of all configured controllers (the natural way to query an HA cluster without knowing in advance which node is alive/primary, e.g. --controller "localhost:9901,localhost:9902,localhost:9903" with 9901 dead) failed outright: Error: cannot connect to localhost:9901,localhost:9902,localhost:9903: [Errno -2] Name or service not known -- the whole comma-joined string was parsed as one bogus hostname.

Environment

Not recorded (migrated from buglog.json).

Reproduction

Not recorded (migrated from buglog.json).

Root cause

push.py and scheduler.py each had their own private _split_controller(controller: str) -> (host, port) that did a single controller.rsplit(':', 1) -- designed only ever to see one host:port. A comma-separated value was never split on ',' at all; it fell through as one literal (unparseable) hostname straight into socket.create_connection via xcecommon.wire.connect, which propagates the resulting socket.gaierror (a plain OSError subclass) unwrapped by design.

Fix

FIXED (2026-09-17, TDD RED->GREEN). Added xceadmin.discovery.resolve_controllers(controller) -> list[(host,port)] (comma-split, whitespace-stripped, per-entry bare-host default port) and xceadmin.discovery.follow_redirects_any(candidates, send_fn) -> (host,port,reply_bytes), which tries each candidate in order via the existing follow_redirects(), catching per-candidate OSError (connection refused, DNS failure) and NoPrimaryError (discovery-level timeout) and moving to the next candidate -- but NOT catching ReplyDecodeError/TooManyRedirectsError, since a genuinely-reachable candidate's protocol-level failure isn't fixed by trying a different node. push.py/scheduler.py's own _split_controller removed; both now call resolve_controllers + follow_redirects_any. cli.py's --controller help text updated on all 4 commands to document the comma-list form. 12 new unit tests in test_discovery.py (single/list/whitespace parsing; first-reachable-wins; skip-refused/skip-DNS-failure/skip-timeout-then-succeed; all-fail raises NoPrimaryError naming every candidate; redirect-following composes correctly with failover; a reachable candidate's decode error does NOT fall through to the next). 2 existing tests per file (test_config_push_mock.py, test_scheduler.py) updated to call the new shared function instead of the removed private one. Full suite 304/304. Live-verified: deployed a 3-node cluster, killed the first-listed controller, confirmed --controller "dead,live1,live2" correctly skips the dead one and reaches a live one (both healthy-cluster and killed-primary scenarios).

Verification

Not recorded (migrated from buglog.json).
