New project src/ZB.MOM.WW.OtOpcUa.Core.Abstractions (.NET 10, BCL-only dependencies, GenerateDocumentationFile=true, TreatWarningsAsErrors=true) defining the contract surface every driver implements. Per docs/v2/plan.md decisions #4 (composable capability interfaces), #52 (streaming IAddressSpaceBuilder), #53 (capability discovery via `is` checks no flag enum), #54 (optional IRediscoverable sub-interface), #59 (Core.Abstractions internal-only for now design as if public). Eleven capability interfaces: - IDriver — required lifecycle / health / config-apply / memory-footprint accounting (per driver-stability.md Tier A/B allocation tracking) - ITagDiscovery — discovers tags streaming to IAddressSpaceBuilder - IReadable — on-demand reads idempotent for Polly retry - IWritable — writes NOT auto-retried by default per decisions #44 + #45 - ISubscribable — data-change subscriptions covering both native (Galaxy MXAccess advisory, OPC UA monitored items, TwinCAT ADS) and driver-internal polled (Modbus, AB CIP, S7, FOCAS) mechanisms; OnDataChange callback regardless of source - IAlarmSource — alarm events + acknowledge + AlarmSeverity enum mirroring acl-design.md NodePermissions alarm-severity values - IHistoryProvider — HistoryReadRaw + HistoryReadProcessed with continuation points - IRediscoverable — opt-in change-detection signal; static drivers don't implement - IHostConnectivityProbe — generalized from Galaxy's GalaxyRuntimeProbeManager per plan §5a - IDriverConfigEditor — Admin UI plug-point for per-driver custom config editors deferred to each driver's phase per decision #27 - IAddressSpaceBuilder — streaming builder API for driver-driven address-space construction Plus DTOs: DriverDataType, SecurityClassification (mirroring v1 Galaxy model), DriverAttributeInfo (replaces Galaxy-specific GalaxyAttributeInfo per plan §5a), DriverHealth + DriverState, DataValueSnapshot (universal OPC UA quality + timestamp carrier per decision #13), HostConnectivityStatus + HostState + HostStatusChangedEventArgs, RediscoveryEventArgs, DataChangeEventArgs, AlarmEventArgs + AlarmAcknowledgeRequest + AlarmSeverity, WriteRequest + WriteResult, HistoryReadResult + HistoryAggregateType, ISubscriptionHandle + IAlarmSubscriptionHandle + IVariableHandle. DriverTypeRegistry singleton with Register / Get / TryGet / All; thread-safe via Interlocked.Exchange snapshot replacement on registration; case-insensitive lookups; rejects duplicate registrations; rejects empty type names. DriverTypeMetadata record carries TypeName + AllowedNamespaceKinds (NamespaceKindCompatibility flags enum per decision #111) + per-config-tier JSON Schemas the validator checks at draft-publish time (decision #91). Tests project tests/ZB.MOM.WW.OtOpcUa.Core.Abstractions.Tests (xUnit v3 1.1.0 matching existing test projects). 24 tests covering: 1) interface independence reflection check (no references outside BCL/System; all public types in root namespace; every capability interface is public); 2) DriverTypeRegistry round-trip, case-insensitive lookups, KeyNotFoundException on unknown, null on TryGet of unknown, InvalidOperationException on duplicate registration (case-insensitive too), All() enumeration, NamespaceKindCompatibility bitmask combinations, ArgumentException on empty type names. Build: 0 errors, 4 warnings (only pre-existing transitive package vulnerability + analyzer hints). Full test suite: 845 passing / 1 failing — strict improvement over Phase 0 baseline (821/1) by the 24 new Core.Abstractions tests; no regressions in any other test project. Phase 1 entry-gate record (docs/v2/implementation/entry-gate-phase-1.md) documents the deviation: only Stream A executed in this continuation since Streams B-E need SQL Server / GLAuth / Galaxy infrastructure standup per dev-environment.md Step 1, which is currently TODO.
