Task 3. Site nodes now open one ZB.MOM.WW.LocalDb-managed database holding OperationTracking and site_events as replicated tables. SiteLocalDbSetup.OnReady applies both schemas and then RegisterReplicated's them. That order is load-bearing and easy to get silently wrong: capture is trigger-based CDC, so rows written before registration are never captured or snapshotted - they would be invisible to the peer forever, with no error anywhere. Storage ships UNCONDITIONALLY, no feature flag. With no peer configured LocalDb is just a local SQLite file, so this is behaviour-equivalent to what site nodes do today. Replication is opt-in and lands in Program.cs (Task 7), which owns the gRPC host the sync endpoint needs. Config: LocalDb:Path added to all EIGHT site-node appsettings (the plan said six - docker-env2's site-x pair exists too), plus the dev template and the wonder-app-vd03 production sample. All ten are required, not optional: LocalDbOptions.Path is validated with ValidateOnStart, so a site node without it fails fast at startup. That is the desired posture, and it is what caught ActorPathTests - the one Host fixture that actually starts a host - whose config now sets the path too. Note the path choice fixes an existing data-loss bug in passing: site-tracking.db and site_events.db both defaulted to CWD-relative paths (/app/...), outside the mounted volume, so they were silently lost on every container recreate. The consolidated database lives on /app/data. Tests are container-built against the REAL SiteServiceRegistration.Configure, not a hand-assembled ServiceCollection - this family has shipped three wiring defects that only a real graph would catch (inert Secrets replicator 0.2.0, singleton deadlock 0.2.2, Secrets.Ui missing IAuditWriter). They assert the library's own view of what is registered rather than that we called the right method. Verified (all after the change): dotnet build ZB.MOM.WW.ScadaBridge.slnx -> 0 Error(s), 0 Warning(s) Host.Tests -> 294 passed (5 new, red-first) SiteRuntime.Tests -> 530 passed CentralUI.Tests -> 925 passed Commons.Tests -> 684 passed Communication.Tests -> 312 passed SiteEventLogging.Tests-> 70 passed Claude-Session: https://claude.ai/code/session_01BL2Vu1ESDQ9SCN4gVKkdts
