Publish a link definition into the lattice, allowing it to be cached and delivered to the appropriate capability provider instances

Requests the removal of a link definition. The definition will be removed from the cache and the relevant capability providers will be given a chance to de-provision any used resources

Instructs the provider to store the NATS credentials/URL for a given lattice. This is designed to allow a single capability provider (or multiple instances of the same) to manage multiple lattices, reducing overhead and making it easier to support secure multi-tenancy of lattices.

Instructs all listening hosts to use the enclosed credential map for authentication to secure artifact (OCI/bindle) registries. Any host that receives this message will delete its previous credential map and replace it with the enclosed. The credential map for a lattice can be purged by sending this message with an empty map
