Row 79 executed its own prescribed remedy without waiting for a second
corruption: all ten rig data dirs (8 docker/ nodes + 2 docker-env2/ site
nodes) move from virtiofs bind mounts to named docker volumes
(scadabridge-<node>-data), seeded in place with both rigs stopped and
live-verified (site-a localDbReplicationConnected=true / backlog 0 over
the migrated files; env2 stable, 0 restarts). The feared inspectability
loss is moot — OrbStack exposes volumes at ~/OrbStack/docker/volumes/.
The rebuild surfaced latent env2 drift (pre-Secrets-0.6.2 image): env2
now carries the x-secrets-store-env posture + central data volumes.
Row 93's silent maintenance trap is now loud: SiteEventsSchemaCalibrationTests
pins the site_events columns/indexes the EventLogPurgeService size model is
calibrated against, failing with a pointer to the memo §4 recalibration on
any schema drift. Rows 92 (accepted by design) and 94 (standing tripwire)
annotated accordingly.
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.
Add ActiveNodeHealthCheck that returns 200 only on the Akka.NET cluster
leader, enabling Traefik to route traffic to the active central node and
automatically fail over when the leader changes. Also fixes AkkaClusterHealthCheck
to resolve ActorSystem from AkkaHostedService (was always null via DI).
Multi-stage Dockerfile with NuGet restore layer caching, per-node appsettings
with Docker hostnames, shared bridge network with infra services, and
build/deploy/teardown scripts. Ports use 90xx block to avoid conflicts.
