chore(agents): add a machine-wide Playwright browser resource budget
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.

# Browser Automation with playwright-cli
|
||||
|
||||
## Resource Budget (MUST)
|
||||
|
||||
One Playwright browser session may be active at a time, machine-wide. The budget is shared by every worktree and by any other checkout that ships this wrapper, because the contended resource is machine RAM and CPU rather than the repository. Playwright disables normal background throttling, so hidden 5chan pages keep P2P and rendering work active after a check.
|
||||
|
||||
- During iteration, use Chrome/Blink only. Run the full cross-browser matrix once the change is ready for final verification.
|
||||
- Open every fresh session through `./scripts/pw-session.sh open <session> ...`; it acquires the shared browser slot.
|
||||
- Reuse the same engine session for desktop and mobile by resizing it.
|
||||
- Close it with `./scripts/pw-session.sh close <session>` in a finally-style cleanup before opening another engine. `close` stops the browser even when the lock was already lost, so it is always the right cleanup call.
|
||||
- Run browser engines and profiler batches sequentially. Never spawn browser-driving agents in parallel.
|
||||
- Exit code 75 means the slot is busy. Finish non-browser work and retry, or block on `./scripts/pw-session.sh open --wait[=SECONDS] <session> ...` (default 300s). Do not bypass the lock.
|
||||
- Never use `playwright-cli close-all` or `kill-all` while concurrent agents may own sessions.
|
||||
- A lock left behind by an interrupted workflow clears itself: the next `open` reclaims any slot whose browser is no longer running. Inspect the holder with `./scripts/pw-session.sh status`, which reports whether that browser is still alive. `release <session>` is a last resort for the rare case where `status` cannot verify the browser state.

# Browser Automation with playwright-cli
|
||||
|
||||
## Resource Budget (MUST)
|
||||
|
||||
One Playwright browser session may be active at a time, machine-wide. The budget is shared by every worktree and by any other checkout that ships this wrapper, because the contended resource is machine RAM and CPU rather than the repository. Playwright disables normal background throttling, so hidden 5chan pages keep P2P and rendering work active after a check.
|
||||
|
||||
- During iteration, use Chrome/Blink only. Run the full cross-browser matrix once the change is ready for final verification.
|
||||
- Open every fresh session through `./scripts/pw-session.sh open <session> ...`; it acquires the shared browser slot.
|
||||
- Reuse the same engine session for desktop and mobile by resizing it.
|
||||
- Close it with `./scripts/pw-session.sh close <session>` in a finally-style cleanup before opening another engine. `close` stops the browser even when the lock was already lost, so it is always the right cleanup call.
|
||||
- Run browser engines and profiler batches sequentially. Never spawn browser-driving agents in parallel.
|
||||
- Exit code 75 means the slot is busy. Finish non-browser work and retry, or block on `./scripts/pw-session.sh open --wait[=SECONDS] <session> ...` (default 300s). Do not bypass the lock.
|
||||
- Never use `playwright-cli close-all` or `kill-all` while concurrent agents may own sessions.
|
||||
- A lock left behind by an interrupted workflow clears itself: the next `open` reclaims any slot whose browser is no longer running. Inspect the holder with `./scripts/pw-session.sh status`, which reports whether that browser is still alive. `release <session>` is a last resort for the rare case where `status` cannot verify the browser state.

# Browser Automation with playwright-cli
|
||||
|
||||
## Resource Budget (MUST)
|
||||
|
||||
One Playwright browser session may be active at a time, machine-wide. The budget is shared by every worktree and by any other checkout that ships this wrapper, because the contended resource is machine RAM and CPU rather than the repository. Playwright disables normal background throttling, so hidden 5chan pages keep P2P and rendering work active after a check.
|
||||
|
||||
- During iteration, use Chrome/Blink only. Run the full cross-browser matrix once the change is ready for final verification.
|
||||
- Open every fresh session through `./scripts/pw-session.sh open <session> ...`; it acquires the shared browser slot.
|
||||
- Reuse the same engine session for desktop and mobile by resizing it.
|
||||
- Close it with `./scripts/pw-session.sh close <session>` in a finally-style cleanup before opening another engine. `close` stops the browser even when the lock was already lost, so it is always the right cleanup call.
|
||||
- Run browser engines and profiler batches sequentially. Never spawn browser-driving agents in parallel.
|
||||
- Exit code 75 means the slot is busy. Finish non-browser work and retry, or block on `./scripts/pw-session.sh open --wait[=SECONDS] <session> ...` (default 300s). Do not bypass the lock.
|
||||
- Never use `playwright-cli close-all` or `kill-all` while concurrent agents may own sessions.
|
||||
- A lock left behind by an interrupted workflow clears itself: the next `open` reclaims any slot whose browser is no longer running. Inspect the holder with `./scripts/pw-session.sh status`, which reports whether that browser is still alive. `release <session>` is a last resort for the rare case where `status` cannot verify the browser state.

- Chromium-only. Skip on Firefox/WebKit sessions; keep those checks unthrottled.

- Low-spec emulation is a measurement pass, not a machine-resource control. Hold the machine-wide browser slot for the whole pass and close it immediately afterward.

#
|

# Playwright disables normal background throttling, so a hidden 5chan page keeps
|
||||
# doing P2P and rendering work after a check finishes. Agents verifying in
|
||||
# parallel therefore stack whole browser engines on one machine. This wrapper
|
||||
# permits one active Playwright browser at a time and records who holds it.
|
||||
#
|
||||
# The lock is machine-wide, not per-repository: the contended resource is RAM and
|
||||
# CPU, so every checkout that ships this script shares a single slot. Set
|
||||
# PLAYWRIGHT_RESOURCE_LOCK_DIR to isolate a lock (tests, or a deliberate second
|
||||
# slot on a machine with headroom).
|
||||
#
|
||||
# Liveness comes from `playwright-cli list --all`, which reports `status: open`
|
||||
# for a running browser. A lock whose recorded session is no longer open is
|
||||
# stale, and is reclaimed automatically rather than blocking every later
|
||||
# workflow. When playwright-cli cannot be queried the lock is left alone, so a
|
||||
# broken CLI never silently disables the budget.
|
||||
#
|

# PW_SESSION_POLL_SECONDS overrides how often `--wait` re-checks the slot.
