Changes applied

activity-core (railiance01-k3s)

ConfigMap actcore-runtime-config: STATE_HUB_URL → in-cluster service
actcore-state-hub-bridge Deployment scaled to 0
Rollout restart: actcore-worker, actcore-api, actcore-event-router
Source: activity-core/k8s/railiance/20-runtime.yaml

Verified from actcore-api pod:

url http://state-hub.state-hub.svc.cluster.local:8000
{"status":"ok","db":"connected"}

railiance01 host

systemctl --user stop fleet-state-hub-coulombcore
systemctl --user disable fleet-state-hub-coulombcore

:18000 no longer serves State Hub (expected).

Workstation ops-bridge

~/.config/bridge/tunnels.yaml — state-hub-primary:

Field	Before	After
`host`	`92.205.130.254` (coulombcore)	`92.205.62.239` (railiance01)
`remote_host`	`10.43.170.94`	`10.43.68.154`
`actor`	`agt-claude-coulombcore`	`agt-claude-railiance01`

Stale state-hub-coulombcore tunnel on :8000 cleared before primary restart.

Verification

curl -s http://127.0.0.1:8000/state/health
# {"status":"ok","db":"connected"}

curl -s http://127.0.0.1:8000/state/summary
# workstreams 640, tasks 4002

Production topology after Phase 3

workstation :8000 ──state-hub-primary──► railiance01 SSH ──► 10.43.68.154:8000 (state-hub)
activity-core pods ──in-cluster DNS──► state-hub.state-hub.svc.cluster.local:8000
coulombcore state-hub Deployment: scaled 0 (rollback only)

Next: Phase 4–5

Phase 4: sweep checkout migration to /home/tegwick/<slug>
Phase 5: 48–72h stabilization before coulombcore teardown
