# B2 after runtime recording

Revision: [e039e17308](https://git.cafe/pingdotgg/t3code/commit/e039e17308b32c280903c5dd4cd82f2457e0d8f0)

Environment: Linux-6.1.102-x86_64-with-glibc2.39, Node v26.13.0. Production-runtime harness, synthetic config and stub connector. Real CloudManagedEndpointRuntime and Node spawner (passive exit-result observer). Not a real Cloudflare tunnel.

A/B: NodeRuntime.runMain, group signal. C2/C3: Effect.runPromise host intentionally survives parent-only OS signals, explicit runtime scope closure.

Stub registration is an age-based model only: <2000ms stop takes 2300ms, otherwise 15ms. “past-registering-window” is synthetic, never Cloudflare readiness. Runner gates use events, not guessed readiness sleeps. The predecessor/backoff/stub timers are deliberate fixture behavior.

AI-assisted; verified with the tests and tools listed above.
