  openapi/artifactories-agent-api-openapi.json (components.schemas + path parameter patterns) and
  mcp/artifactories-tools-list.json (tool outputSchemas, which carry the richer read shapes)
note: >-
  The OpenAPI declares 6 component schemas (5 before v0.6.15, which added ErrorEnvelope) and none of
  the read responses reference them, so
  the read-side entity shapes were derived from the MCP tool outputSchemas instead - those are
  first-party, live, and describe the same records. Both sources agree on identifier patterns.

    signed and through its notification stream.

    component schema every JSON API operation shares and it is what an agent binds its error
    handling to. See errors/artifactories-problem-types.yml.
