Overview / Motivation
Auto-filed by /daily 2026-07-27 problem sweep (transcript mining, 44 in-window transcripts). Session f56bbb5d (#1735), 2026-07-27T20:21Z (miner H P6).
Goal
The merge-SHA verification must fetch before it compares.
Workflow gap
- Bug observed: the squash-merge SHA returned by gh existed only on the remote; the local subject check ran pre-fetch and read 'fatal: bad object', producing a false MISMATCH that delayed the epm:merged post one round.
- Why it is a workflow gap: the recipe orders the subject check before any fetch of the just-created merge commit.
- Confidence (emitter): medium
- verified-at-filing: unverified hypothesis — verify at plan time: exact current recipe ordering in SKILL.md Step 10d merged-marker block (it churned this week); the incident evidence is the session's own 'fatal: bad object' output (miner-quoted).
Proposed change (candidate diff sketch — refine in planning)
In .claude/skills/issue/SKILL.md (Step 10d merged-marker recipe): insert git fetch origin main before the merge-SHA subject check, or switch the check to gh pr view <PR> --json mergeCommit (no local object needed).
Scope / surfaces
- Primary target:
.claude/skills/issue/SKILL.md
Constraints / invariants
- Workflow-surface only — never experiment code,
configs/, ortasks/. scripts/workflow_lint.pyno-flags run +--check-askspass on touched files; ruff passes where applicable.- This session runs under a
workflow_fix_target:Provenance line — it MUST NOT auto-route its own subagents' workflow-fix candidates (recursion guard).
