- Add JoeAppEngine folder to OPC UA nodes.json (BTCS, AlarmCntsBySeverity, Scheduler/ScanTime)
- Fix DataConnectionActor: capture Self in PreStart for use from non-actor threads,
preventing Self.Tell failure in Disconnected event handler
- Implement InstanceActor.HandleConnectionQualityChanged to mark attributes Bad on disconnect
- Fix LmxFakeProxy TagMapper to serialize arrays as JSON instead of "System.Int32[]"
- Allow DataType and DataSourceReference updates in TemplateService.UpdateAttributeAsync
- Update test_infra_opcua.md with JoeAppEngine documentation
Central and site clusters now communicate via ClusterClient/
ClusterClientReceptionist instead of direct ActorSelection. Both
CentralCommunicationActor and SiteCommunicationActor are registered
with their cluster's receptionist. Central creates one ClusterClient
per site using NodeA/NodeB contact points from the DB. Sites configure
multiple CentralContactPoints for automatic failover between central
nodes. ISiteClientFactory enables test injection.
Central now resolves site Akka remoting addresses from the Sites DB table
(NodeAAddress/NodeBAddress) instead of relying on runtime RegisterSite
messages. Eliminates the race condition where sites starting before central
had their registration dead-lettered. Addresses are cached in
CentralCommunicationActor with 60s periodic refresh and on-demand refresh
when sites are added/edited/deleted via UI or CLI.
New components 18-19: ManagementService (Akka.NET actor on Central exposing
all admin operations via ClusterClientReceptionist) and CLI (console app using
ClusterClient for scripting). Updated HighLevelReqs, CLAUDE.md, README,
Component-Host, Component-Communication, Component-Security.
- Replace "custom protocol" placeholder with full LmxProxy details (gRPC transport, SDK API mapping, session management, keep-alive, TLS, batch ops)
- Add bullet-level requirement traceability, design constraint traceability (52 KDD + 6 CD), split-section tracking, and post-generation orphan check to plan framework
- Resolve Q9 (LmxProxy), Q11 (REST test server), Q13 (solo dev), Q14 (self-test), Q15 (Machine Data DB out of scope)
- Set Central UI constraints: Blazor Server + Bootstrap only, no heavy frameworks, custom components, clean corporate design
Stand up local dev infrastructure (OPC UA, LDAP, MS SQL) with Docker Compose,
Python CLI tools for service interaction, and teardown script. Fix GLAuth config
mount, OPC PLC node format, and document actual DN/namespace behavior discovered
during testing. Resolve Q1-Q8,Q10: .NET 10, Akka.NET 1.5.x, monorepo with slnx,
appsettings JWT, Windows Server 2022 site target.
Audit logging was absorbed into the Configuration Database component (IAuditService),
making the separate Component-AuditLogging.md redundant. Also added tool usage
guidance to CLAUDE.md for Codex MCP model selection.
