Eighth PR of the alarms-over-gateway epic (docs/plans/alarms-over-gateway.md). Mirrors PR E.2's .NET surface on the Python async SDK. Depends on PR E.1 (regen, merged). - GatewayClient.acknowledge_alarm — async unary call routed through the existing _unary helper. ensure_protocol_success raises typed gateway errors for non-OK protocol statuses; map_rpc_error wraps RpcError → MxGatewayAuthenticationError / MxGatewayAuthorizationError on Unauthenticated / PermissionDenied responses. - GatewayClient.query_active_alarms — async iterator over ActiveAlarmSnapshot. Mirrors stream_events_raw's cancel-on-close pattern via a dedicated _canceling_active_alarms_iterator (typed for ActiveAlarmSnapshot). Tests: - 6 new tests in test_alarms.py — request shape, Unauthenticated + PermissionDenied mapping, snapshot streaming, filter prefix passthrough, cancel-on-aclose semantics. - Full Python test suite: 39 passed (was 33; 6 new). CLI verb (alarms subscribe / acknowledge / query-active) deferred — the SDK surface is what lmxopcua consumes; CLI follow-up shares the JSON output shape with E.2's .NET CLI for cross-language tooling.
