        User-bound credential carrying an identity: either a session JWT
        or a user access token (`at:*`) generated from the user settings UI.
        Send as `Authorization: Bearer <token>`.
        Org API keys (`iak_*`) are **not** accepted here - they carry
        no user identity. Use the `x-prismeai-api-key` header instead
        (see `OrgApiKeyAuth`).

      description: |
        Organization API key (`iak_{orgSlug}_{uuid}`), managed from the
        AI Governance UI. Unlike `Authorization: Bearer`, this credential
        is **not** tied to a user identity - it is bound to the org and
        its effective access is defined by the scopes / permission rules
        attached to it (it can be restricted to a single project, or kept
        broader - e.g. usable across AI Governance, Agent Factory and
        LLM Gateway).
        Send as `x-prismeai-api-key: iak_...`.
