Phase 7 plan decisions #16, #17, #19, #21 implementation. Durable local SQLite queue absorbs every qualifying alarm event; drain worker forwards batches to Galaxy.Host (reusing the already-loaded 32-bit aahClientManaged DLLs) on an exponential-backoff cadence; operator acks never block on the historian being reachable. ## New project Core.AlarmHistorian (net10) - AlarmHistorianEvent — source-agnostic event shape (scripted alarms + Galaxy-native + AB CIP ALMD + any future IAlarmSource) - IAlarmHistorianSink / NullAlarmHistorianSink — interface + disabled default - IAlarmHistorianWriter — per-event outcome (Ack / RetryPlease / PermanentFail); Stream G wires the Galaxy.Host IPC client implementation - SqliteStoreAndForwardSink — full implementation: - Queue table with AttemptCount / LastError / DeadLettered columns - DrainOnceAsync serialised via SemaphoreSlim - BackoffLadder 1s → 2s → 5s → 15s → 60s (cap) - DefaultCapacity 1,000,000 rows — overflow evicts oldest non-dead-lettered - DefaultDeadLetterRetention 30 days — sweeper purges on every drain tick - RetryDeadLettered operator action reattaches dead-letters to the regular queue - Writer-side exceptions treated as whole-batch RetryPlease (no data loss) ## New IPC contracts in Driver.Galaxy.Shared - HistorianAlarmEventRequest — batched up to 100 events/request per plan Stream D.5 - HistorianAlarmEventResponse — per-event outcome (1:1 with request order) - HistorianAlarmEventOutcomeDto enum (byte on the wire — Ack/RetryPlease/PermanentFail) - HistorianAlarmEventDto — mirrors Core.AlarmHistorian.AlarmHistorianEvent - HistorianConnectivityStatusNotification — Host pushes proactively when the SDK session drops so /alarms/historian flips red without waiting for the next drain - MessageKind additions: 0x80 HistorianAlarmEventRequest / 0x81 HistorianAlarmEventResponse / 0x82 HistorianConnectivityStatus ## Tests — 14/14 SqliteStoreAndForwardSinkTests covers: enqueue→drain→Ack round-trip, empty-queue no-op, RetryPlease bumps backoff + keeps row, Ack after Retry resets backoff, PermanentFail dead-letters one row without blocking neighbors, writer exception treated as whole-batch retry with error surfaced in status, capacity eviction drops oldest non-dead-lettered, dead-letters purged past retention window, RetryDeadLettered requeues, ladder caps at 60s after 10 retries, Null sink reports Disabled status, null sink swallows enqueue, ctor argument validation, disposed sink rejects enqueue. ## Totals Full Phase 7 tests: 160 green (63 Scripting + 36 VirtualTags + 47 ScriptedAlarms + 14 AlarmHistorian). Stream G wires this into the real Galaxy.Host IPC pipe.
