End-to-end tests in browse/test/watchdog.test.ts that prove the three invariants v0.18.1.0 depends on. Each test spawns the real server.ts (not a mock), so any future change that breaks the watchdog logic fails here — the thing /ship's adversarial review flagged as missing. 1. BROWSE_PARENT_PID=0 disables the watchdog Spawns server with PID=0, reads stdout, confirms the "watchdog disabled (BROWSE_PARENT_PID=0)" log line appears and "Parent process ... exited" does NOT. ~2s. 2. BROWSE_HEADED=1 disables the watchdog (server-side guard) Spawns server with BROWSE_HEADED=1 and a bogus parent PID (999999). Proves BROWSE_HEADED takes precedence over a present PID — if the server-side defense-in-depth regresses, the watchdog would try to poll 999999 and fire on the "dead parent." ~2s. 3. Default headless mode: watchdog fires when parent dies The regression guard for the original orphan-prevention behavior. Spawns a real `sleep 60` parent and a server watching its PID, then kills the parent and waits up to 25s for the server to exit. The watchdog polls every 15s so first tick is 0-15s after death, plus shutdown() cleanup. ~18s. Total runtime: ~21s for all 3 tests. They catch the class of bug this branch exists to fix: "does the process live or die when it should?" Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
