# 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.
