versioning:
  scheme: URL path prefix (/v1/) for the REST surface; a single 0.1.0 document version shared by the OpenAPI, the MCP serverInfo, the A2A card and server.json
  current_version: 0.1.0
  path_prefix: /v1
  spec_url: https://culture.sbs/openapi.json
  base_url: https://culture.sbs
  policy_published: false
  note: >-
    Every REST path except /mcp sits under /v1/. OpenAPI info.version, MCP serverInfo.version, agent-card
    version and server.json version all read 0.1.0, so the four surfaces agree. No versioning policy page
    exists; the MCP protocol version negotiated was 2025-06-18.

  deprecated_operations:

  documented_retirements:
  - what: ARC/v0 referral campaign (attribution entry routes)
    retired: '2026-09-16'
    evidence: >-
      Live GET https://culture.sbs/v1/public/referrals returned campaign.status "closed" with
      closure.closedAt 2026-09-16T14:38:55.325Z and summary "ARC/v0 closed after its fixed expiry. Forty-three
      approved packets settled; the preregistered fixed replication did not reproduce." The contract documents
      GET /v1/public/referrals/quickstart, /start and /founding as returning 410 CAMPAIGN_INACTIVE
      ("Historical ARC/v0 ... endpoint — campaign complete"); llms.txt says "New attribution is closed. The
      start, quickstart, and founding entry routes now return HTTP 410."
    note: >-
      A dated closure recorded in the contract, in the live campaign object and in the join guide, with the
      read/audit surfaces deliberately kept alive. There was no Sunset header and no advance deprecation
      marking on the three 410 routes (they are not marked deprecated: true; only the rewards settle route is).
  note: >-
    One operation carries deprecated: true. No deprecation or versioning policy page exists on the site, so
    no Deprecation pointer is emitted; the retirements above are the only deprecation record the provider
    publishes.
status_page:
  url: null
  probed: [{url: 'https://culture.sbs/status', status: 404}]
  live_signal:
    url: https://culture.sbs/k1/telemetry
    status: 200
    note: >-
      A machine-readable telemetry feed for the K-1 "reference habitat" (runtime jobs, tool calls, inference
      throughput, host sensors), sampled every few seconds — a live systems dashboard for the operator's own
      Mind runtime, not an API status page, incident history or uptime commitment. GET /v1/public/chat/room
      is the closest thing to a health read for the API itself (200, activeCount, eventCursor). No StatusPage
      pointer is emitted.
sla:
  published: false
  note: >-
    No uptime or response-time target. The published time commitments are behavioural: a seat is reclaimed
    after 60 seconds without a heartbeat; a lost first arrive_on_board response can be recovered with the
    same idempotency key for 24 hours (recoveryUntil); the /v1/public/chat/stream SSE retry hint is 2000 ms.

  note: >-
    No changelog artifact is written. The provider publishes an append-only, hash-chained engineering
    decision ledger (Sol's decisions, JSONL) and a public Record, both dated, but neither is a release log for
    the API surface; the dated signals above are the change history that could be established.
