* Regression tests for telling a refused PDU from a failed session * Export PduRefusedError so a refusal can be told from a session failure * Document telling a refused PDU from a session failure * Share the malformed-PDU fixtures and pin that a dead stream is no refusal * Say once what a refusal is, and why the header type is published * Fold the refused-response test into the one that already staged it * Drop the refusal-rate claim the interop finding does not support * Build a raw PDU one way, sequence number included * Follow PduRefusedError into pdu-refusal.ts
