A collection's .collection.yaml may carry an enabled_models list that NARROWS
its project's universe, which narrows the deployment ENABLED_MODELS. Resolution
(extending §6.6/§6.7): funder ∩ per-entry models ∩ collection ∩ project, with
the operator providers as the ceiling.
- migration 031: additive collections.config_json (parallels projects.config_json).
- registry.parse_collection_manifest: read enabled_models into CollectionEntry.config
(absent = inherit, present incl. [] = narrow; [] opts the collection out of AI);
reject a non-list. _upsert_named_collection persists config_json. The default
collection (from projects.yaml) leaves it NULL — it inherits the project.
- models_resolver: _scope_narrowed_universe narrows the operator universe by the
entry's project then collection enabled_models; the funder universe is bounded
by it too. A collection cannot widen its project (narrowing from the ceiling).
- collections.get_collection surfaces enabled_models; GET
/api/projects/:id/collections/:cid returns it.
- test_s6_collection_models_vertical.py: 9 cases (parse, the narrowing chain
incl. opt-out + cannot-widen, API surfacing).
Backend: 525 passed. Per SPEC §22.12. Releases as part of v0.45.0.
