resume

Resume (two-process)

Demonstrates the disconnect → reconnect → replay flow. The client opens a session, runs a job to completion (so all events sit in the runtime's EventLog), drops the transport without session.bye, then opens a fresh transport and resumes the same session_id. The client passes a synthetic last_event_seq=2 to prove the runtime replays the tail (seq > 2) — the same code path that recovers from a real mid-stream crash. The fresh resume_token is verified to differ from the prior one.

Run

In one terminal:

pnpm tsx examples/resume/server.ts

In a second terminal:

pnpm tsx examples/resume/client.ts

What it demonstrates

• §13.3 / §6.3 resume after disconnect using session.hello.payload.resume.
• §6.3 resume_token rotation on every welcome (old token single-use).
• §8.3 monotonic, gap-free event_seq across the reconnect; replayed events advance the local counter so live events resume from there.
