From ef3a07b2d5d27e581ff7c4d55bfa752cae9b002d Mon Sep 17 00:00:00 2001 From: Raphael Maenle Date: Tue, 9 Jun 2026 10:53:40 +0200 Subject: [PATCH] tests: E87 slot-map mismatch + multi-LP wire scenarios MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Four new test cases: * S3F19 verify with matching map → SlotMapVerifyAck::Accept and CSMS lands in Read on the equipment side. * S3F19 verify with disagreeing map → Mismatch ack and CSMS lands in Mismatched. * 4 LPs + 4 carriers, host verifies CAR-1 (mismatch) and CAR-3 (match) — only those two carriers move on the CSMS axis; CAR-2/CAR-4 stay NotRead. Confirms per-carrier independence. * Multi-LP E84 handshake sequencing (load then unload) round-trips through Idle. Documents that the current E84StateMachine is per-equipment, not per-port — a future per-port FSM would update this test alongside. Closes #11 in the test-gap backlog.
