"""A hub-signed token is a session only if it says so, and only while it lasts.
One Ed25519 key signs four kinds of token: user access, node access, revocation
broadcasts and MHP federation tokens. `decode_access_token` used to accept any
of them that carried a valid signature, requiring no `exp` and binding no
purpose — so a token with no expiry was honoured, and the separation between
the four rested only on which fields each consumer happened to read. A
revocation token is even handed back in the body of `POST /v1/admin/revoke` and
pushed to every node, so nodes hold hub-signed tokens.
These are refusals: `decode_access_token` must require `exp`, `sub` and a known
`scope`, so a token with no expiry, a revocation token, or an MHP token can
never be mistaken for a session — while a real login token still works.
