"""Public UI reproduction driver. Requires a paired, isolated T3 dev server.

Run each revision as a real app, never swap helper outputs into another build:
  git switch --detach <revision>
  vp run dev --no-seed --home-dir /tmp/ev-24611/<revision>
Launch headed Chromium on Xvfb with CDP 19246 and a task-owned profile.
Pair manually with that server's startup token (never publish the token).
The app auto-creates an empty server project/thread on this VM.
Run configure, send, then plan; stop server before changing revision.
Use a fresh isolated server home for each revision. No live userdata access.

Browser for this round: Chrome 156 headless Linux, actual independently running apps.
This reproduction recipe adapts the earlier driver. This round acquired seed state
through the built-in preview UI, not by executing this script end to end. Use
capture-real.py for the executed capture driver and provenance.json for actual sends.
Provider: actual installed Codex gpt-6.1-sol, low effort, full-access mode.
The custom unavailable text-generation model is intentional: title generation
fails and leaves the client-produced title seed visible. Turn provider works.
All input and mutations use the app UI; eval only reads DOM or blurs focus.
