Per-session-serialized blocking send that enqueues via the CB-103 injector (poller delivers) and blocks on a rendezvous resolved by the worker's structured bridge_reply, or a typed 200/202 outcome. No status-polling completion, no terminal scrape. GET /sessions/{id}/status. Reworked from an initial poll+scrape draft after a high-effort review found the polling completion unreliable; all findings fixed.
