Switch site host to WebApplicationBuilder with Kestrel HTTP/2 gRPC server,
add GrpcPort/keepalive config, wire SiteStreamManager as ISiteStreamSubscriber,
expose gRPC ports in docker-compose, add site seed script, update all 10
requirement docs + CLAUDE.md + README.md for the new dual-transport architecture.
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)
Per-site gRPC client for central-side streaming subscriptions to site
servers. SiteStreamGrpcClient manages server-streaming calls with
keepalive, converts proto events to domain types, and supports
cancellation via Unsubscribe. SiteStreamGrpcClientFactory caches one
client per site identifier.
Includes InternalsVisibleTo for test access to conversion helpers and
comprehensive unit tests for event mapping, quality/alarm-state
conversion, unsubscribe behavior, and factory caching.
Proto3 definition with SiteStreamService (server streaming), Quality and
AlarmStateEnum enums with UNSPECIFIED=0, google.protobuf.Timestamp for
cross-platform timestamps. Pre-generated C# stubs checked in (no protoc
at build time). 10 roundtrip tests covering serialization, oneof
discrimination, and Timestamp<->DateTimeOffset conversion.
Define the SiteStreamService proto for real-time instance event
streaming (attribute value changes, alarm state changes) from site
nodes to central. Add pre-generated C# stubs following the existing
LmxProxy pattern, gRPC NuGet packages with FrameworkReference for
ASP.NET Core server types, and proto roundtrip tests.
