Rongsong Shen 5522d6f274 feat(ha-commit-barrier-rollout): mark_job_* idempotency/ordering guards (task 6.2) ... Guards at the top of mark_job_start/finish/update under the caller's job lock, before BEFORE_EVENT: duplicate (FINISH on terminal) → INFO no-op skipping the AFTER_EVENT hook (no WAL append, lsn frozen); terminal→non-terminal backward (START/UPDATE) → WARN reject preserving state. Shared job_state_is_backward predicate provably admits every production forward merge (PDONE/PERR/suspend bit-OR) while rejecting overwrites. mark_job_fail intentionally unguarded (its merges are always terminal-forward; job_ctrl pre-gates terminal). 5/5 guard tests green; full job-lifecycle suite green; census 0 FAIL.		2026-06-13 04:54:36 +00:00
