    Agent-first asset management. The web UI is built on this API and nothing
    else, beside signing in at /api/auth. Send `Authorization: Bearer <key>`: a
    key works in one workspace with one scope, and scopes are a ladder: read <
    propose < write < admin. People signed in to the app carry a session cookie
    instead, and their scope is what their grants add up to: on the
    organization, the workspace, or single collections and assets. A scope shown
    as needed on the workspace is also enough on the one collection or asset a
    route acts on. Agents (MCP at POST /api/v1/mcp) usually get `propose`: what
    they add waits for a human.
