Contracts-016 (Conventions): QueryActiveAlarmsRequest.session_id header replaced with the unambiguous "Clients may leave session_id empty; the gateway currently ignores it and serves the session-less central-monitor cache. A future version may use it to scope the snapshot to one session." Removes the ambiguity that the prior "reserved for future use" wording introduced. Contracts-017 (Documentation): The rpc QueryActiveAlarms comment now includes the alarm_filter_prefix description: "QueryActiveAlarmsRequest.alarm_filter_prefix optionally narrows the snapshot to alarms whose alarm_full_reference starts with the given prefix; an empty prefix returns the full set." Both are proto-comment-only changes — no wire-format impact, no field renumbering, and the regenerated MxaccessGateway.cs / MxaccessGatewayGrpc.cs carry only the doc-comment delta. Added the additive-only regression guard QueryActiveAlarmsRequest_PinsFieldNumbersAndRoundTripsPrefixFilter to ProtobufContractRoundTripTests — pins session_id=1 / client_correlation_id=2 / alarm_filter_prefix=3 by descriptor lookup and round-trips the message with and without the filter populated. Verification: dotnet build src/ZB.MOM.WW.MxGateway.slnx clean; ProtobufContractRoundTripTests 40/40 passing. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
