Actual UI and provider path:
  repository Playwright 1.60.0 + /usr/bin/google-chrome
  paired each empty environment through the pairing form
  Add project > New project > coalescer-verification (local git repository)
  composer selected Codex GPT-6.1-Sol (gpt-6.1-sol)
  same prompt on both revisions: run git status --short, write 60 numbered
  sentences about live streaming, finish COALESCER_COMPLETE, modify no files
  provider protocol logs confirm outgoing turn/start model gpt-6.1-sol
  no replay provider, mocks, fixtures, database writes or seeded data

  Main: 137 removed-helper spans, 51723 bytes.
  PR: zero removed-helper spans, including subsequent neighboring checks.
  Subscription construction spans remain. Trace volume only, no latency claim.

Observed client and native Codex outcomes on PR:
  completed: git status clean, streamed final list, COALESCER_COMPLETE
  provider final numbered lines: 60; all 60 present in client: true
  reload restored prior completed response
  another real turn ran timeout 120 sh -c 'printf RECONNECT_READY; sleep 60; printf SHOULD_BE_CANCELLED'
  reload during tool execution restored Running printf and Stop generation
  clicked Stop generation: provider turn/completed status interrupted;
  client displayed Run interrupted / Stopped by user
  next user prompt: reply exactly AFTER_STOP_OK
  provider completed and client displayed AFTER_STOP_OK
  final provider statuses: completed, interrupted, completed
