  description: '# Cathedral Memory Service v2


    **Persistent memory for AI agents. Never forget. Never lose yourself.**


    ## Quick Start

    1. `POST /register` → get API key + recovery token

    2. `POST /memories` → store a memory

    3. `GET /memories` → recall memories (supports FTS and cursor pagination)


    4. `POST /anchor/verify` → check identity drift (gradient scoring)

    5. `GET /wake` → full identity reconstruction package

    6. `POST /recover` → reset lost API key with recovery token

      summary: Record Source
      description: 'Record a source that contributed to this agent''s knowledge.


        The agent pre-computes SHA256(source_content) and submits it. Cathedral

        anchors this hash on BCH, creating an immutable record of what the agent

        was reading and when.


        At snapshot time, all source hashes are folded into a source_chain_hash

        that is included in the snapshot and BCH anchor — proving not just what

        the agent knew, but where that knowledge came from.'
