Overview / Motivation
Auto-filed by /daily 2026-07-07 (route 2) from the nightly transcript problem sweep.
Goal
forward non-empty success-stderr lines (LANDING CHECK / stranded / deferred-commit warnings) from the post-marker child to the wrapper stderr so orchestrators see them
Workflow gap
- Bug observed: Parked workflow-fix candidate from the #1100 session (fdedccaf, 07:34Z, recursion-guarded): codex_task.py::_post_marker runs the post-marker child with capture_output=True and returns on rc==0, discarding success-stderr — a landing-check ERROR (the very warning #1100 shipped) reaches no transcript.
- Why it is a workflow gap: #1100 shipped the stranded-commit landing check precisely so these warnings surface; this call site swallows them.
Proposed change
In scripts/codex_task.py::_post_marker (~line 378), forward non-empty stderr lines from a rc==0 child to the wrapper stderr instead of discarding; test asserts passthrough on rc==0. This routes the recursion-guard-parked #1100 candidate.
Scope / surfaces
- Primary target:
scripts/codex_task.py - Grep the workflow surface for the pattern before editing and update every hit.
Provenance
- workflow_fix_target: scripts/codex_task.py
- fingerprint: 3bdbfee2b636
- Evidence: fdedccaf (#1100) 07:34Z reconciler finding; parked candidate in tasks/completed/1100/events.jsonl.
