chore(ha-commit-barrier-rollout): final validation GO — spec implemented (task 7.2)

Browse source 
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.

> `[x]` = spec generated (requirements/design/tasks approved, ready for implementation). Implementation tracked via each spec's tasks.md; implement in roadmap order (cross-spec review 2026-06-11: four specs touch ha_dispatch_gate / raft_cb_become_follower in disjoint-but-adjacent regions).
- [x] ha-commit-engine — commit.c per-LSN majority engine + quorum accounting fixes, wired behind job submit. Dependencies: none. (specs done 2026-06-11; **IMPLEMENTED 2026-06-12**: 12/12 tasks, validate-impl GO, 467 tests green; deferred follow-ups in its tasks.md §Implementation Notes)
- [x] ha-commit-barrier-rollout — classification table, commit-first-then-reply sweep, RETAIN facts, config barrier, idempotency guards. Dependencies: ha-commit-engine. (specs done 2026-06-11: 5 reqs / 6 components / 16 sub-tasks; verified classification supersedes umbrella table for STOP/RESUME/UPDATE/FAIL)
- [x] ha-commit-barrier-rollout — classification table, commit-first-then-reply sweep, RETAIN facts, config barrier, idempotency guards. Dependencies: ha-commit-engine. (specs done 2026-06-11; **IMPLEMENTED 2026-06-13**: 16/16 tasks, validate gate GO, 508 controller tests green under ASAN. Fixed bug-447 (key_find found-rc leak — queue/host control was silently unpersisted+unreplicated in production) and bug-396 (worker fact loss on quorum-loss gate rejection); task 5.2 needed one remediation round (wired the missing production config-ACK ingestion — would have bricked multi-member config upgrades — + kept the barrier off the iomgr thread). Logged not-fixed: bug-448 (job_ctrl ref leak), bug-451 (RUSAGE va_list OOB read). Barrier-before-state-removal precondition for ha-single-leader-role satisfied)
- [x] ha-single-leader-role — promotion no-op + own-term gate, CTRL_PRIMARY_COMMITTING removal. Dependencies: ha-commit-engine, ha-commit-barrier-rollout (HARD: barrier before state removal). (specs done 2026-06-11: 2 reqs / 7 components / 11 sub-tasks)
- [x] ha-convergence-recovery — demotion truncate+self-restart, rejoin reconciliation, egress watermark filter, ACK-driven catch-up, quorum logging. Dependencies: ha-commit-engine (E2E additionally needs ha-single-leader-role). (specs done 2026-06-11: 9 reqs / 7 components / 13 sub-tasks)
