DIRECTORY_AUTH_STRATEGIES

const DIRECTORY_AUTH_STRATEGIES: readonly ["podcast-index"];

The auth strategies Trove knows how to sign a directory lookup with. A directory provider names one and the platform applies it, so no source author ever handles the credential.

Declared here as the closed vocabulary: a provider naming a strategy nothing implements should fail when the catalog is built, not at a user’s first search — where it would look like “no results” rather than a bug.
