  Version and freshness markers read from the live documents on 2026-09-19: the two OpenAPI copies,
  the two agent cards, agents.json, the gateway freshness beacon, and the JSON-RPC -32601 message that
  enumerates legacy method aliases. The provider publishes no versioning policy, deprecation policy,
  SLA or status page; those absences are the finding.
versioning:
  scheme: semver-in-document (no URI or header versioning)
  current:
    openapi_gateway_host: 1.3.0        # https://ai.rsperformance.online/.well-known/openapi.json
    openapi_canonical_host: 1.2.2      # https://rsperformance.online/.well-known/openapi.json — one minor behind, missing gatewayAnswerRouting
    a2a_agent_card: 2.5.0              # /.well-known/agent-card.json, protocolVersion 0.3.0
    a2a_legacy_card: 2.2.0             # /.well-known/agent.json

  note: >-
    Versions are declared inside each document and drift between hosts (OpenAPI 1.2.2 vs 1.3.0).
    Endpoints themselves are unversioned (POST /, /api/search). No Stripe-Version-style header, no
    /v1/ path segment.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  legacy_surfaces:
    - what: JSON-RPC legacy method aliases SendMessage, SendStreamingMessage, GetTask, ListTasks, CancelTask, SubscribeToTask
      status: still served; announced only inside the -32601 error text as "legacy aliases"
      replacement: message/send, message/stream, tasks/get, tasks/list, tasks/cancel, tasks/subscribe
    - what: /.well-known/agent.json (pre-0.3 agent card path)
      status: still served with an OLDER card (2.2.0, 4 skills) than the canonical path (2.5.0, 9 skills)
      replacement: /.well-known/agent-card.json
    - what: diagnostic_search MCP tool
      status: live; described by the server as a "compatibility bridge for legacy Diagnosta clients"
      replacement: semantic_search
  note: No published timeline for retiring any of the above.
sla:
  url: null
  uptime_target: null
  note: None published. The A2A card's x_rs_ai_friendly block states a fair-use rate limit and cache TTL (>= 600 s on /.well-known/agent-card.json) but no availability commitment.
