The classifier's Anthropic and ACP provider keys were written by hand in the
secret store's UI. The controller now stores them: GET
/api/review-classifier/keys says whether each is set and when it changed, and
PUT /api/review-classifier/keys/{runtime} writes one. No route answers a key.
The controller's store policy gains create and update on the two leaves with
no read of their values, and a metadata read for the set state. The swarm UI's
classifier settings card gets a key form beside the settings, saved apart
because it goes to the secret store.
credentials.md drops the target-shape framing and keeps the rules, where a
secret lives, the swarm- and hive-level secrets and how to add one. The queue
responder's keys, per-principal identities, how a reader reaches the store, the
store UI's login and where the root lives move to
4-implementation/swarm/credentials.md. The per-secret reference moves to
4-implementation/swarm/credentials-reference.md. Links and comments follow.
