Get referenced blob
Returns a blob the state attestation references directly, through an iroh collection, or through the agent definition it names; any other CID returns 404. Readable by an admin and by users bound to the agent. With alt=media, a 200 response is the blob's raw bytes (application/octet-stream, exact Content-Length, Content-Disposition: attachment) instead of the JSON envelope; errors stay JSON. The JSON envelope refuses a blob over 16 MiB with 422 referenced_blob_too_large; read it with alt=media, which has no limit of its own. max_bytes refuses a larger blob the same way, before it is loaded.

BearerAuth· API key in header "Authorization" — Type "Bearer" followed by a space and a sign-in token: a Guardian Platform JWT, or an OIDC ID token in a standalone deployment.ApiKeyAuth· API key in header "Authorization" — Type "Bearer" followed by a space and a Guardian Platform API key. Project-scoped routes and registration tokens check the key's scopes and project binding. Per-agent routes accept a key bound to no project that has empty scopes or full access, which acts as its holder, or a scope for what the route does: submit_agent_assessments reads an agent (its detail, configurations, state history and the files a state references, definitions, tools and operating profile, as its assessments rest on), view_agent_certifications reads its certifications, and manage_programs or review_agent_assessments attach a certification. A state's raw snapshot and findings, its audit exchanges and plugin events, and saving its operating profile take full access. A scope counts only while the key's holder still holds that permission in the key's organization, which auth-service reports as keyHeldScopes. A key never acts as an admin, so its holder's binding to the agent still decides.
