aiti-crash-fatal

Crash drill extension: verifies the pi-web extension crash self-healing/recovery chain. Three crash entry points (partial-crash philosophy: only one thing breaks at a time, each with backup / recoverable):

• 🧨 Crash extension startup: POST /crash-ext writes the crash flag → after reload the startup throws → a ⚠ "startup failed" indicator appears at the bottom-left of the page (page/API/client all alive) → POST /restore-ext idempotently clears and recovers (or recover from the ⚠ popup; auto-recovers after 60s)
• 💥 Crash the page: POST /corrupt backs up app/page.tsx and writes in a render-throw version → refresh → 🚑 global-error rescue page → POST /restore restores (falls back to git show HEAD: when the backup is missing)
• 🧱 Crash the build: POST /corrupt-build injects an import of a nonexistent export at the top of components/AppShell.tsx → the Turbopack Build Error overlay takes over full-screen (compile errors happen before the React tree is built, so global-error can't catch them) → the rescue-hook 🚑 banner automatically guides to /rescue.html (static pages under public/ stay outside the compile graph) → POST /restore-build restores
• Entry: the red 💥 Fatal button in the dev page's top toolbar (a custom copyable confirm dialog picks the scenario); GET /status shows each scenario's broken state
• dev-isolation only: requests are 403-rejected outright when NODE_ENV !== development; deploys only to ~/.pi/web-dev/, never to production
