Split the 657-line operation service into eor, submit, and verify modules, add the AGENT_REVOKED and KEY_RETIRED codes the Backend already emits, and condense every multi-line comment. Mirror Node, Python, and Go at 2.1.0 with the deep-health 503, non-idempotent retry, rotation grace, and path-encoding fixes. Document which routes and response fields the self-hosted server does not provide. Claude-Session: https://claude.ai/code/session_01Agoc9bRVE9KL7mmWtey9Vq
