MintJWT reads the signing pool file on every call and indexes Authorities[0] directly. localjwtauthority.Unmarshal reports no error for JSON that carries no authorities, so an empty or incompletely written pool file reaches that index and panics. sessionidjwt.Sign then type-asserts the signing key without checking, so a pool entry whose algorithm does not match its key type panics as well. Neither is recoverable: nothing in the server installs a panic-recovery interceptor, so a configuration error in the pool file takes down ate-api-server on the first MintJWT call rather than returning an error to the caller. Check the pool for authorities before selecting one, and check each key type assertion in Sign. MintCert already guards an empty session CA pool the same way; this brings the JWT path in line with it. The signing-authority selection moves into a helper so it can be tested without standing up an OIDC issuer to satisfy the client-JWT verification that precedes it. Both packages had no tests; the ones added here also pin the existing behavior of the working paths.

MintJWTindexesAuthorities[0]from the actor JWT signing pool file, andactoridjwt.Signtype-asserts the signing key without checking it, so a pool file carrying no authorities (whichlocaljwtauthority.Unmarshalaccepts without error) or an algorithm that does not match its key panics instead of returning an error. Nothing in the server installs a panic-recovery interceptor, so that configuration error takes down ate-api-server on the firstMintJWTcall, andMintCertalready guards the same situation for its own pool. This adds the missing checks plus the first tests for both packages, which also pin the behavior of the paths that already worked.
