Tests for product #9, stacked directly on its branch. Three focused cases cover recipient authenticity, failed output before acknowledgement, and progress beyond 100 unmarked rows. The live driver provisions fresh identities outside messenger and requires real pear/SAP; it has no skip mode. This round incorporates the product’s shared history-reading helper without changing any test.
At e33910dd130bb6eb037562501ef8369d4bbebdf2, b1 passed all 14 CLI tests, one spike test and both builds. Fresh m3simplifier0725 identities passed exact delivery, unrelated filtering, real nonmember refusal, forged-mark refusal, unmarked restart replay, idempotent durable marks, post-mark restart with positive fresh-message liveness, persisted SAP acknowledgement and history. The backlog regression originally failed at 100/101 deliveries.
