Document that migration and cutover prerequisites are closed, T01 is
unblocked, and T02–T04 wait on operator stabilization sign-off and the
Inter-Hub rollback retirement sequence.

`CORE-WP-0005` finished 2026-07-03: `hub.coulomb.social` ingress now serves Core
Hub; Inter-Hub compatibility, staging import, dual-run smokes, and production
cutover gates are closed. Haskell retirement no longer waits on migration work —
it waits on a short post-cutover stabilization window, operator approval to
retire the Inter-Hub rollback deployment, and the four tasks below.

Rename or archive the low-risk IHP probe repo first, preserving any useful notes about the failed build/deploy path. Rename or archive `ihp-railiance-probe` (`coulomb/ihp-railiance-probe`),
preserving `INTENT.md` and `DeploymentBlueprint.md` notes about the failed
IHP/GHC/Nix build path. `IRP-WP-0001` is already `done`; this task is
unblocked and can proceed independently of T02–T04.

Rename `inter-hub` to `inter-hub-haskell` only after Core Hub compatibility, migration, and production cutover gates pass. Rename `inter-hub` to `inter-hub-haskell` after operator stabilization sign-off
and approval to retire the Inter-Hub rollback path. Compatibility, migration,
and production cutover gates from `CORE-WP-0005` are satisfied; the Inter-Hub
k8s deployment in namespace `inter-hub` still runs as rollback-only (ingress
already moved — see `k8s/railiance-production/README.md`).
Scope when unblocked: Forgejo repo rename, registry/Helm/CI path updates in
`railiance-apps` and `railiance-forge`, and eventual scale-down of the
rollback deployment after the stabilization window closes.

Update docs and workplans in consuming repos so Inter-Hub references point to Core Hub or explicitly to `inter-hub-haskell` for historical context. After T02, update docs and workplans in consuming repos so production Inter-Hub
references point to Core Hub and historical Haskell context explicitly names
`inter-hub-haskell`. Known stale surfaces: `ops-hub` INTENT/SCOPE/README and
readiness docs; `activity-core` railiance probes and sink vocabulary;
`the-custodian` service catalog and drain plans. Core Hub specs and migration
fixtures already use `inter-hub-haskell` as the bundle `source` name.
## Progress 2026-07-07 — upstream gate cleared
`CORE-WP-0005` archived (`260703-CORE-WP-0005-data-migration-and-cutover.md`).
Production cutover executed 2026-07-03: Core Hub serves `hub.coulomb.social`;
post-flip reconcile import was idempotent (0 created / 28 updated / 0 errors);
rollback remains one kubectl command while the Inter-Hub deployment stays
running through stabilization.
Revised sequencing:
1. **T01** — unblocked; archive `ihp-railiance-probe` first (low risk).
2. **T02** — cutover prerequisites met; blocked on operator stabilization
sign-off and approval to retire the Inter-Hub rollback deployment.
3. **T03** — blocked on T02 and confirmation that no repo still schedules
Haskell builds through haskelseed.
4. **T04** — blocked on T02 so references use the final repo name.
