  note: >-
    Captures API Evangelist enrichment as an Overlay so the harvested spec at
    openapi/_original/rtcstats-openapi.json and its YAML twin stay byte-faithful
    to what rtcstats.com serves. Nothing here changes the provider's contract.

      x-notes: >-
        Two-phase chunked flow. Individual multipart chunks return {"success": true}
        and cost nothing; only the JSON assemble request runs the pipeline and
        consumes a credit. Assemble detection is shape-based, so a raw JSON dump
        body still works for small files.

    update:
      x-agentic-consequence: write
      x-credit-cost: 1
      x-notes: >-
        Does not store the session by default — pass ?save=true to persist it, at
        which point the response carries rtcstatsId and rtcstatsUrl. aiSummary is
        always null on this operation.
  - target: $.paths['/v1.0/enrich'].post
    update:
      x-agentic-consequence: write
      x-credit-cost: 1
      x-notes: >-
        Stateless projection for a self-hosted rtcstats-server: returns scores,
        observationsCount, observations and userAgentData only, and never stores
        the session. Observation records are flat and SQL-friendly — only type and
        severity are always present; absent fields are omitted, never null.

      x-notes: >-
        Catalog of observation types the analyzer can emit. This is the value space
        for the observationTypes filter on GET /v1.0/sessions and the list_sessions
        MCP tool — read it first when building a filter.
      x-mcp-tool: null
  - target: $.paths['/v1.0/sessions'].get
    update:
      x-agentic-consequence: read
      x-credit-cost: 0
      x-mcp-tool: list_sessions
      x-pagination:
        supported: false
        note: Returns {total, data[]} with no limit/offset/cursor; narrow with the fifteen filters instead.

    update:
      x-agentic-consequence: read

      x-mcp-tool: get_session
      x-notes: >-
        embedUrl is omitted from the response on non-Enterprise plans. aiSummary is
        null until background generation completes.

    update:
      x-agentic-consequence: destructive
      x-credit-cost: 0
      x-mcp-tool: null
      x-notes: Deliberately absent from the MCP surface — all MCP tools are read-only.

    update:
      x-transport: streamable-http
      x-protocol-version: '2025-06-18'
      x-notes: >-
        MCP Streamable HTTP transport, stateless JSON-RPC 2.0. initialize and
        tools/list answer anonymously; tools/call requires the Bearer application JWT.
  - target: $.components.schemas.Error
    update:
      x-error-codes:
        - {code: parsing_issue, status: 415, meaning: Corrupt or unsupported dump; generic message}
        - {code: other_issue, status: 415, meaning: Invalid file or format too old; specific message}
      x-note: The full errorCode value space is not published; only the two 415 codes are documented.
