Add a local /services router (source of truth for the catalog itself):
- GET /services/catalog with hosting_type / development_type / maturity_level /
status filters (eager-loads all four extensions)
- GET /services/{slug}
- POST /services/catalog upsert-by-slug, applying the dimension extensions;
first_party.repo_slug resolves to a managed_repos FK.
Extensions are read/written via session.get (not the relationship attribute) to
avoid async lazy-load. /tpsc/* is left intact for dependency snapshots. 7 tests.
