verification run: 2026-11-01, Linux Boat VM
main: github/main 955e2bfbb5 (separate /home/user/main worktree)
PR: bdcdedf8790ce3a163676c4069f9c56588f7664c (exact contributor head)
primary runtime: Node v24.22.1
browser: repo Playwright 1.60.0, /usr/bin/google-chrome
Each checkout installed with vp i. Only one dev server ran at a time.
main server/web: 16733/8693; PR server/web: 13773/5733. Servers stopped by captured process-group PID.

Real-app setup: added /home/user/sqlite-verification-repo through the web Add project > Local folder flow.
Submitted matching prompts through the actual composer with Codex gpt-6.1-sol on main and PR:
  Reply exactly: sqlite baseline verified. Do not run tools or change files.
Both rendered the real provider reply: sqlite baseline verified.
PR server restart preserved the conversation. A fresh Chrome context loaded it, submitted a follow-up,
and rendered: sqlite follow-up verified. Recording contains actual submission and response.
A live CLI rename propagated to the web client during the recording, then was restored.

Contention method: separate Node process opens the app-created statev2.sqlite,
runs PRAGMA locking_mode=EXCLUSIVE; BEGIN EXCLUSIVE; SELECT count(*) FROM sqlite_schema,
and emits HELD. Launch the real t3 project rename CLI through strace -f -e trace=fcntl.
Only after strace reports an actual EAGAIN/EACCES lock conflict, schedule release one second later.
This avoids releasing the lock before the CLI reaches SQLite.
All CLI calls have an outer timeout. No database rows or app fixtures were injected.
