PR:   628147266014051fe76875877528aa89ecfa9d84
Codex CLI: 0.164.0; provider: Codex; model: gpt-6.1-sol
Client: dev web app, Playwright 1.60.0, /usr/bin/google-chrome
Dependencies installed with vp i on each checkout.
Only one dev server ran at a time, each with isolated .t3 state and --no-seed.
Project /home/user/restart-verification was added through the app's Add project flow.
Provider model and binary path were selected through the app.
A project UserPromptSubmit hook waited before input recording. No mocks or seeded records.
A transparent binary wrapper captured app-server PIDs for targeted crash cleanup.

Prompt in both cases:
Reply with exactly RESTART_INPUT_26861 and nothing else. Do not use tools.

MAIN REPRO
05:49:53 hook entered; running provider turn existed; original request absent from Codex history.
Dev server crashed by its retained process-group PID 25828 while hook was held.
05:50:14 restart recovery terminalized the source run and resumed natively.
Codex history had only session instructions, no original request.
Actual assistant response: i'll follow these instructions for the session.
Expected RESTART_INPUT_26861 was missing.
