+### T02 — Inter-Hub repo rename and rollback retirement
+
+- Forgejo/Gitea rename `coulomb/inter-hub` → `coulomb/inter-hub-haskell` on
+  railiance01 (`forgejo.coulomb.social`) and CoulombCore (`gitea.coulomb.social`)
+- Rollback deployments scaled to `0` on CoulombCore (`inter-hub` namespace) and
+  railiance01; stale railiance01 ingress for `hub.coulomb.social` removed
+- `hub.coulomb.social` continues to serve Core Hub (`/healthz` 200)
+- `inter-hub` repo: README retirement banner, CI `workflow_dispatch` only,
+  registry paths updated to `inter-hub-haskell`

+
+### T04 — Cross-repo references updated
+
+- `ops-hub` INTENT/SCOPE/README → Core Hub production surface
