Overview / Motivation
Auto-filed by /daily 2026-07-03 (backfill run 2026-07-04) from the day's transcript problem sweep.
Goal
(a) On commit-failure-after-successful-append, return success-with-warning (or have the retry path check the events tail for the just-appended marker before re-posting). (b) In the shared commit helper, detect MERGE_HEAD and bounded-wait / route through scripts/sync_repo_root.py instead of attempting a partial commit.
Workflow gap
- Bug observed: (a) post_event appends to events.jsonl BEFORE the git commit; on an index.lock commit failure the standing retry recipe re-posts, landing the SAME marker 3x (#823 loop session, 07-03). (b) new_plan_version's commit crashed 'fatal: cannot do a partial commit during a merge' when a concurrent merge held MERGE_HEAD on the shared root (#911 session, 07-03).
- Why it matters: Both are mid-mutation crash/concurrency seams in the canonical state API; #898 covered set_status but not these two.
- Confidence (emitter): medium
Scope / surfaces
- Primary target:
src/explore_persona_space/task_workflow.py - Grep the workflow surface for the pattern before editing and update every hit; list them in the plan.
Constraints / invariants
scripts/workflow_lint.pydefault run passes; ruff on touched files passes.- This task was auto-filed by the /daily three-route classifier (route 2 — behavior/logic change, independent review).
