+### 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`
+
+### T03 — Haskell build lane parked
+
+- `sand-boxer/profiles/profile.vm-haskell-build.yaml` marked `retired`
+- `railiance-forge/docs/gitea-actions-runner-substrate.md` notes haskelseed lane
+  parked; no new Haskell/IHP image builds scheduled
+- `ops-bridge/wiki/OpsBridge.md` documents haskelseed build lane retirement
+
+### T04 — Cross-repo references updated
+
+- `ops-hub` INTENT/SCOPE/README → Core Hub production surface
+- `activity-core/SCOPE.md` → Core Hub ops evidence intake
+- `the-custodian/ops/service-inventory.yml` → `inter-hub-haskell` retired entry
+- `the-custodian/docs/core-hub-cutover-decision-coupling.md` → fallback no longer
+  required
+- `railiance-apps` chart metadata and `docs/inter-hub-on-railiance01.md` retired
+- `ihp-railiance-probe/README.md` link updated
