Additional information:
The affected “00 - Narita Arrival (Chiba)” task is internally identified as a Codex task associated with the Japan 2028 project. Therefore, the more likely chain is:
project-associated task → project-specific rollout path handling → \\?\ prefix retained → archiving fails
Chat mode may correlate with it, but the evidence does not yet prove that Chat mode causes it.
Add these observations to the issue:
- Only tasks created inside a project have failed so far.
- Comparable projectless tasks archive normally.
- Affected tasks contain \\?\ in threads.rollout_path.
- Removing only that prefix allows archiving.
- Opening or updating the task can restore the prefix.
- The same path behavior occurs on another Windows computer.
- No unusual CODEX_HOME, links, or path configuration exists.
