Foundational PRs from lmx_mxgw_impl.md, all green. Bodies only — DI/wiring deferred to PR 1+2.W (combined wire-up) and PR 3.W. PR 1.1 — IHistorianDataSource lifted to Core.Abstractions/Historian/ Reuses existing DataValueSnapshot + HistoricalEvent shapes; sidecar (PR 3.4) translates byte-quality → uint StatusCode internally. PR 1.2 — IHistoryRouter + HistoryRouter on the server Longest-prefix-match resolution, case-insensitive, ObjectDisposed-guarded, swallow-on-shutdown disposal of misbehaving sources. PR 1.3 — DriverNodeManager.HistoryRead* dispatch through IHistoryRouter Per-tag resolution with LegacyDriverHistoryAdapter wrapping `_driver as IHistoryProvider` so existing tests + drivers keep working until PR 7.2 retires the fallback. PR 2.1 — AlarmConditionInfo extended with five sub-attribute refs InAlarmRef / PriorityRef / DescAttrNameRef / AckedRef / AckMsgWriteRef. Optional defaulted parameters preserve all existing 3-arg call sites. PR 2.2 — AlarmConditionService state machine in Server/Alarms/ Driver-agnostic port of GalaxyAlarmTracker. Sub-attribute refs come from AlarmConditionInfo, values arrive as DataValueSnapshot, ack writes route through IAlarmAcknowledger. State machine preserves Active/Acknowledged/ Inactive transitions, Acked-on-active reset, post-disposal silence. PR 2.3 — DriverNodeManager wires AlarmConditionService MarkAsAlarmCondition registers each alarm-bearing variable with the service; DriverWritableAcknowledger routes ack-message writes through the driver's IWritable + CapabilityInvoker. Service-raised transitions route via OnAlarmServiceTransition → matching ConditionSink. Legacy IAlarmSource path unchanged for null service. PR 3.1 — Driver.Historian.Wonderware shell project (net48 x86) Console host shell + smoke test; SDK references + code lift come in PR 3.2. Tests: 9 (PR 1.1) + 5 (PR 2.1) + 10 (PR 1.2) + 19 (PR 2.2) + 1 (PR 3.1) all pass. Existing AlarmSubscribeIntegrationTests + HistoryReadIntegrationTests unchanged. Plan + audit docs (lmx_backend.md, lmx_mxgw.md, lmx_mxgw_impl.md) included so parallel subagent worktrees can read them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
