Ships the data + runtime layer of Stream E. The SignalR hub and Blazor /hosts page refresh (E.2-E.3) are follow-up work paired with the visual-compliance review per Phase 6.4 patterns — documented as a deferred follow-up below. Configuration: - New entity DriverInstanceResilienceStatus with: DriverInstanceId, HostName (composite PK), LastCircuitBreakerOpenUtc, ConsecutiveFailures, CurrentBulkheadDepth, LastRecycleUtc, BaselineFootprintBytes, CurrentFootprintBytes, LastSampledUtc. - Separate from DriverHostStatus (per-host connectivity view) so a Running host that has tripped its breaker or is nearing its memory ceiling shows up distinctly on Admin /hosts. Admin page left-joins both for display. - OtOpcUaConfigDbContext + Fluent-API config + IX_DriverResilience_LastSampled index for the stale-sample filter query. - EF migration: 20260419124034_AddDriverInstanceResilienceStatus. Core.Resilience: - DriverResilienceStatusTracker — process-singleton in-memory tracker keyed on (DriverInstanceId, HostName). CapabilityInvoker + MemoryTracking + MemoryRecycle callers record failure/success/breaker-open/recycle/footprint events; a HostedService (Stream E.2 follow-up) samples this tracker every 5 s and persists to the DB. Pure in-memory keeps tests fast + the core free of EF/SQL dependencies. Tests: - DriverResilienceStatusTrackerTests (9 new, all pass): tryget-before-write returns null; failures accumulate; success resets; breaker/recycle/footprint fields populate; per-host isolation; snapshot returns all pairs; concurrent writes don't lose counts. - SchemaComplianceTests: expected-tables list updated to include the new DriverInstanceResilienceStatus table. Full solution dotnet test: 1042 passing (baseline 906, +136 for Phase 6.1 so far across Streams A/B/C/D/E.1). Pre-existing Client.CLI Subscribe flake unchanged. Deferred to follow-up PR (E.2/E.3): - ResilienceStatusPublisher HostedService that samples DriverResilienceStatusTracker every 5 s + upserts DriverInstanceResilienceStatus rows. - Admin FleetStatusHub SignalR hub pushing LastCircuitBreakerOpenUtc / CurrentBulkheadDepth / LastRecycleUtc on change. - Admin /hosts Blazor column additions (red badge when ConsecutiveFailures > breakerThreshold / 2). Visual-compliance reviewer signoff alongside Phase 6.4 admin-ui patterns. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
