Neighboring smoke checks on PR head, real provider:
  UI: Add project > Local folder > /home/user/pr23856-scenario/
  Created project from a real git repository with README.md containing: verification workspace
  UI: model picker > GPT-6.1-Sol (Codex), low effort, full access.
  Prompt: Read README.md with a shell command. Do not modify any files. Reply with the exact line from the file, followed by FIRST_TURN_OK.
  Tool visible in real client: cat README.md
  Assistant: verification workspace FIRST_TURN_OK
  Prompt: Without running tools or changing files, repeat the line you read from README.md, followed by FOLLOWUP_OK.
  Assistant: verification workspace FOLLOWUP_OK
  Reloaded the real client. Both responses persisted and history expansion showed the shell command.
  git -C /home/user/pr23856-scenario status --short: empty.

Changed Muse behavior was NOT exercised. No mocks, fixtures, or demo turns used.
Missing Muse runtime/login prevents reproducing the baseline bug and verifying child-id transitions, deduplication, workflow tasks, completion, failure, cancellation, release, and restart recovery.
