From 25fa7b993b456a0923436c512869b1e73fd4e07c Mon Sep 17 00:00:00 2001 From: ATX Bot Date: Tue, 9 Jun 2026 11:49:57 +0200 Subject: [PATCH] Add 16 tests for main_state_machine.ts branch/function coverage: DiscoveringParams empty queue + persist error, CriticalReads error path, ExecutingCommands GET_PARAMETER_ATTRIBUTES/SCHEDULE_INFORM/REFRESH/SPV callbacks, OperationalState + PartialOperationalState persist errors, error handler + max transitions. Coverage: 93.5% stmts, 73% branches, 77% functions. All 830 tests pass.
