+# Inter-Hub → Core Hub migration export
+
+`inter_hub_export.sql` is a read-only query against the legacy Inter-Hub
+Postgres database (`interhub` on net-kingdom-pg) that emits a
+`core-hub.migration.v1` bundle covering hubs, hubCapabilityManifests,
+apiConsumers, apiKeys (prefix + hash only, no plaintext), widgets, and
+interactionEvents. Field names are aliased from Inter-Hub's snake_case columns
+to the bundle's camelCase contract.
+
+## Run
+
+```bash
+kubectl exec -i -n databases net-kingdom-pg-1 -- \
+  psql -U postgres -d interhub -tA < scripts/migration/inter_hub_export.sql \
+  > interhub-bundle.json
+
+# validate (no DB needed)
+PYTHONPATH=src uv run python scripts/core_hub_cli.py migration validate interhub-bundle.json
+
+# import into a target (CORE_HUB_DATABASE_URL); run in-cluster for staging
+python scripts/core_hub_cli.py migration import --dry-run interhub-bundle.json
+python scripts/core_hub_cli.py migration import interhub-bundle.json
+```
+
+The importer is idempotent (upsert by id): re-running updates in place, never
+duplicates. `api_keys` carry only `keyPrefix` + `keyHash`, so no secret material
+transits the bundle.

 With operator approval, switch production traffic such as `hub.coulomb.social` to Core Hub. Keep rollback available until stabilization passes.

+## Progress 2026-07-02 — staging import completed
+
+Built the Inter-Hub exporter (`scripts/migration/inter_hub_export.sql`, read-only
+against the `interhub` DB on net-kingdom-pg) emitting a validated
+`core-hub.migration.v1` bundle (sha256 `e1b53b7f2d67ef7a…`): 1 hub (`ops-hub`),
+1 manifest, 2 api consumers, 8 api keys (prefix+hash only), 15 widgets, 1
+interaction event. `migration validate` passed with zero errors/warnings and no
+secret material.
+
+Imported into Core Hub staging via an in-cluster Job (staging DB URL from
+`core-hub-staging-env` secretKeyRef, bundle via ConfigMap): dry-run `ok=true`
+(28 would-create), real import created all 28 records with zero errors, and a
+second run proved idempotency (created=0, updated=28, no duplicates).
+Server-side confirmed: the imported `ops-hub` hub and its 15 widgets are visible
+via `/api/v2/*`. T02 done; the staging DB now holds real Inter-Hub data for the
+T03 dual-run smokes.
