d8d1901901 docs(steering): sync steering + xce-audit-invariants skill after Jul 13-18 work
- ha-async-io.md: document the same-batch endpoint lifetime hazard
  (bug-1447) and its ref-whole-batch-before-dispatch fix pattern
- xce-audit-invariants SKILL.md: add object-lifetime-within-a-dispatch-batch
  as a 6th audit dimension, so a future pass checks other batch loops
  (vtaskmgr drain, peer-list iteration) for the same shape
- product.md: replace the stale "HA consistency family is the current
  focus" framing with the actual 2026-07-18 status (umbrella complete,
  9-spec validate-impl batch closed, job-array-single-wal-record shipped)
- roadmap.md: correct 5 entries that were stale relative to actual spec
  status (ha-consistency-invariants/ha-wal-replication/libxce-failover
  pulled out of "In Flight", ha-term-safety and raft-drive-async marked
  implemented+GO, raft-sim-conformance and job-array-single-wal-record
  given closure annotations) -- struck through, not deleted, per this
  file's own additive-update convention
- testing.md: document that meson's aggregate Fail:0 can mask Unity
  sub-group failures -- always check the standalone binary's own summary
- src/controller/CLAUDE.md: fix a stale line-citation for the votedFor
  atomicity invariant (had drifted onto unrelated post-election code)

b469b174a2 docs(job-array-single-wal-record): sync spec docs with phase-7 residual-gap closure
brief/requirements updated to reflect the reopened-and-now-closed
post-GO gap-closure phase (tasks 7.1-7.3); adds research.md capturing
the investigation trail; roadmap.md reflects current spec status.

78fe058242 docs: mark raft-apply-decoupling done, fix raft-drive-async header checkboxes
raft-apply-decoupling: 32/32 tasks complete, validate-impl GO (79/79 test
groups, live smoke boot verified) -- update roadmap's In Flight entry with
outcome, residuals, and follow-ups.

raft-drive-async: all 17 sub-tasks were already [x] but the 4 phase-header
checkboxes were never ticked, leaving tasks.md looking incomplete. Confirmed
via source (g_drive_async_configpush_offload defaults to 1) and prior
session notes that all 4 phases genuinely landed and flipped ON in
production; checkboxes now match reality.

5f307e297b docs: promote raft-apply-decoupling spec family from /kiro-discovery
Adds the Raft Apply-Ordering & Hook Decoupling roadmap phase: canonical
pre-hooks -> raft commit -> apply -> notify ordering, with the raft protocol
step lifted out of the notification hook fan-out (root of the bug-795/828/
851/1060 divergence family). Decision: apply-after-commit via a single
shared apply_committed_entry() seam reused by online apply and restart
replay.

- raft-drive-async: full spec docs (brief/requirements/research/design)
  committed alongside its already-tracked tasks.md; async-drive prerequisite
  for the apply-decoupling work, sequenced to start first (threatens
  failover liveness today).
- raft-apply-decoupling: new spec (brief + facts-in-raft.md) covering the
  apply seam and the facts (WAL_MODE_RETAIN) apply-timing question (open
  decision D1).
- job-array-single-wal-record: promoted from backlog to a tracked spec,
  sequenced after raft-apply-decoupling.
- ha-consistency-invariants: add criterion 2.9 (Facts-Apply invariant),
  documenting the current on-receipt fact-reaction deviation this family
  will reconcile.
- raft-commit-safety / raft-log-replication: reconcile spec.json phase to
  "implemented" (both were mislabeled tasks-generated despite full 18/18
  and 24/24 task completion + raft_sim GO).

20e59d0b42 checkpoint: bug-851 root cause + raft TLA+ conformance spec family
Investigation & fixes (failover committed-job loss):
- root-cause bug-851 on an owned 3-node cluster: chaotic failover causes
  silent committed-prefix divergence (WAL hdr.term always 0; two leaders
  per term; no (term,lsn) reconcile). Evidence in repro-851/ + INVESTIGATION.
- live-validated fixes 848/849/850 (recovery-on-promotion, advertise real
  applied_lsn, persist-layer contiguity guard); add waldump WAL inspector.

Specs (strict raft.tla conformance — library owns the log):
- TLA-gap-analysis.md: impl vs raft/raft.tla, gaps G1-G6.
- raft-log-replication, raft-commit-safety, raft-sim-conformance: extend
  src/lib/raft to own log/commit/verification via callbacks (specs generated,
  cross-spec review passed).
- ha-term-safety: controller-side adapter + config marker (R1-R7); design done.
- config-upgrade-snapshot: R8 descoped here (deps entity-bearing-snapshots, bug-857).
- roadmap + buglog (851/854/857) + .wolf knowledge updated.

dbc631664d docs(ha-single-leader-role): sync steering + contributor docs to three-state model + own-term gate (task 6.1) 2026-06-13 14:58:55 +00:00
678b7f89d5 chore(ha-commit-barrier-rollout): final validation GO — spec implemented (task 7.2)
Full controller suite green under ASAN (508 PASS / 0 FAIL / 0 sanitizer
aborts, independently re-censused). All 16 tasks complete; barrier
before reply proven across all restructured opcodes; classification
guard active; barrier-before-state-removal precondition for
ha-single-leader-role satisfied. spec phase=implemented; roadmap
updated. Sub-spec 2 of 4 of the ha-consistency-invariants umbrella.

06135954ff chore: baseline snapshot — prior-session work + ha-consistency-invariants spec family
Pre-existing uncommitted work: ha-repl-hardening payload data plane (7.x),
heartbeat liveness fix (Req 1.3), connection-reuse ASAN fixes, doc cleanup.
New: ha-consistency-invariants umbrella (requirements/design/research) and
its four implementation sub-specs (specs generated via batch, cross-spec
review applied), steering roadmap + product.md Raft+CP decision.
