CompleteRead logged a Warning for every non-Good status on every poll and latched Degraded for all of them. Now a bad tag warns once per bad episode (re-armed when it reads Good, and on re-initialise), a comms-class status (BadCommunicationError / BadTimeout) degrades with LastSuccessfulRead preserved, and any other status - the device answered and refused this tag - advances LastSuccessfulRead with no state change. Read-path exception handlers now go through MarkCommsFault, so they never downgrade Faulted. Refs #739 Claude-Session: https://claude.ai/code/session_01Ub9hGmYLQvn9XETzw7CMsT
