Joseph Doherty	2cd43b6992	feat: update DebugStreamBridgeActor to use gRPC for streaming events ... After receiving the initial snapshot via ClusterClient, the bridge actor now opens a gRPC server-streaming subscription via SiteStreamGrpcClient for ongoing AttributeValueChanged/AlarmStateChanged events. Adds NodeA/ NodeB failover with max 3 retries, retry count reset on successful event, and IWithTimers-based reconnect scheduling. - DebugStreamBridgeActor: gRPC stream after snapshot, reconnect state machine - DebugStreamService: inject SiteStreamGrpcClientFactory, resolve gRPC addresses - ServiceCollectionExtensions: register SiteStreamGrpcClientFactory singleton - SiteStreamGrpcClient: make SubscribeAsync/Unsubscribe virtual for testability - SiteStreamGrpcClientFactory: make GetOrCreate virtual for testability - New test suite: DebugStreamBridgeActorTests (8 tests)	2026-03-21 12:14:24 -04:00
Joseph Doherty	fd2e96fea2	feat: replace debug view polling with real-time SignalR streaming ... The debug view polled every 2s by re-subscribing for full snapshots. Now a persistent DebugStreamBridgeActor on central subscribes once and receives incremental Akka stream events from the site, forwarding them to the Blazor component via callbacks and to the CLI via a new SignalR hub at /hubs/debug-stream. Adds `debug stream` CLI command with auto-reconnect.	2026-03-21 01:34:53 -04:00
Joseph Doherty	389f5a0378	Phase 3B: Site I/O & Observability — Communication, DCL, Script/Alarm actors, Health, Event Logging ... Communication Layer (WP-1–5): - 8 message patterns with correlation IDs, per-pattern timeouts - Central/Site communication actors, transport heartbeat config - Connection failure handling (no central buffering, debug streams killed) Data Connection Layer (WP-6–14, WP-34): - Connection actor with Become/Stash lifecycle (Connecting/Connected/Reconnecting) - OPC UA + LmxProxy adapters behind IDataConnection - Auto-reconnect, bad quality propagation, transparent re-subscribe - Write-back, tag path resolution with retry, health reporting - Protocol extensibility via DataConnectionFactory Site Runtime (WP-15–25, WP-32–33): - ScriptActor/ScriptExecutionActor (triggers, concurrent execution, blocking I/O dispatcher) - AlarmActor/AlarmExecutionActor (ValueMatch/RangeViolation/RateOfChange, in-memory state) - SharedScriptLibrary (inline execution), ScriptRuntimeContext (API) - ScriptCompilationService (Roslyn, forbidden API enforcement, execution timeout) - Recursion limit (default 10), call direction enforcement - SiteStreamManager (per-subscriber bounded buffers, fire-and-forget) - Debug view backend (snapshot + stream), concurrency serialization - Local artifact storage (4 SQLite tables) Health Monitoring (WP-26–28): - SiteHealthCollector (thread-safe counters, connection state) - HealthReportSender (30s interval, monotonic sequence numbers) - CentralHealthAggregator (offline detection 60s, online recovery) Site Event Logging (WP-29–31): - SiteEventLogger (SQLite, 6 event categories, ISO 8601 UTC) - EventLogPurgeService (30-day retention, 1GB cap) - EventLogQueryService (filters, keyword search, keyset pagination) 541 tests pass, zero warnings.	2026-03-16 20:57:25 -04:00
Joseph Doherty	8c2091dc0a	Phase 0 WP-0.10–0.12: Host skeleton, options classes, sample configs, and execution framework ... - WP-0.10: Role-based Host startup (Central=WebApplication, Site=generic Host), 15 component AddXxx() extension methods, MapCentralUI/MapInboundAPI stubs - WP-0.11: 12 per-component options classes with config binding - WP-0.12: Sample appsettings for central and site topologies - Add execution procedure and checklist template to generate_plans.md - Add phase-0-checklist.md for execution tracking - Resolve all 21 open questions from plan generation - Update IDataConnection with batch ops and IAsyncDisposable 57 tests pass, zero warnings.	2026-03-16 18:59:07 -04:00
