Playwright disables normal background throttling, so a hidden 5chan page keeps doing P2P and rendering work after a check finishes. Agents verifying in parallel across worktrees stacked whole browser engines on one machine. Add scripts/pw-session.sh, a wrapper that permits one active Playwright browser at a time and records who holds it: - The lock is machine-wide, not per-repository, because the contended resource is RAM and CPU. Every worktree and checkout shares one slot. - Acquisition is an atomic mkdir. Stale locks clear themselves: `open` reclaims any slot whose recorded browser is no longer `status: open` in `playwright-cli list --all`, so an interrupted workflow cannot strand the budget. When that list cannot be read the lock is left alone, so a broken CLI never silently disables the budget. - `open` exits 75 when the slot is busy; `--wait[=SECONDS]` blocks instead. - `close` always stops the browser, even when the lock was already lost, and never releases a slot held by a different session. - `status` reports the holder and whether its browser is still alive. Agent policy now runs browser engines and profiler batches sequentially, uses Chrome/Blink during iteration and the full engine matrix only for final verification, and never uses `close-all` or `kill-all` while other agents may own sessions. Covered by scripts/pw-session.test.js.

# scripts/AGENTS.md

These rules apply to `scripts/**`. Follow the repo-root `AGENTS.md` first, then use this file for automation and workflow helpers.
|
|
|
|
- Keep scripts non-interactive and idempotent. Print the command, URL, branch, or path being acted on so failures are diagnosable.
|
|
- Use repo-relative paths and environment variables instead of user-specific absolute paths.
|
|
- For dev-server helpers, default to `https://5chan.localhost`, but allow a branch-scoped `*.5chan.localhost` route when the launcher is avoiding a Portless name collision. Start the Portless HTTPS proxy on port 443 before registering routes so legacy `~/.portless` state on port 1355 is not reused. Respect the existing `PORTLESS=0` fallback instead of hard-coding alternate ports. For USB Android preview, `scripts/start-android-usb.mjs` mirrors bitsocial-web: `adb reverse` plus Vite on `127.0.0.1`, then `am start` VIEW to open the default browser when the port is listening (disable with `ANDROID_USB_OPEN_BROWSER=0`).
|
|
- Keep shell helpers thin. When logic becomes stateful or cross-platform, prefer a Node script.
|
|
- `scripts/pw-session.sh` owns the machine-wide Playwright resource lock shared by every worktree and checkout, so its default lock path must stay repository-independent. Keep acquisition atomic, treat `playwright-cli list --all` as the only liveness oracle and leave the lock alone when it cannot be read, require exact-owner release, and close the named browser before normal release; never broaden cleanup to unrelated sessions.
|
|
- Git and worktree helpers must validate input and default to safe operations.
|
|
- If a helper deletes local branches automatically, document the exact eligibility checks and keep the behavior conservative.
