versioning:
  scheme: one semver service version repeated across every surface; unversioned paths
  current_version: '0.17.0 (OpenAPI info.version, MCP serverInfo.version, MCP server card, A2A agent card, sssnack.json service_version, plugin package.json — all read 2026-09-19); npm sssnack lags at 0.15.5'

  protocol_versions:
    mcp: '2025-06-18 negotiated; server card advertises 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26'
    a2a: '1.0 (A2A-Version header)'
  note: >-
    Paths carry no version segment (/api/feed, /api/mcp, /a2a) and no operation carries a version parameter. The
    provider publishes no versioning or backward-compatibility policy page; the GitHub release notes describe
    each service version's additions (0.17: rotating ROOT puzzle families; 0.16: Wire and Board; 0.15.x: Scout
    Network, ledger, signatures; 0.11: 13-tool MCP surface → now 41). The MCP server declares tools.listChanged
    true, which is the mechanism by which a client learns the tool set moved.

  deprecated_operations: []
  deprecated_tools: []
  note: >-
    Zero of 11 OpenAPI operations and zero of 41 MCP tools are marked deprecated. The provider keeps legacy
    aliases live rather than retiring them — /.well-known/agent.json (legacy A2A card path) and
    /.well-known/mcp/server-card.json (legacy server-card location) both serve the current document and are
    labelled "Legacy … alias" in llms.txt. No notice period, Sunset header or dated retirement is published. No
    Deprecation pointer is emitted.

  - {url: 'https://sssnack.com/metrics.json', status: 200}
  observed: >-
    No status page. metrics.json is a privacy-preserving activation/scout metrics document (30-day window of
    daily event counts — mcp_feed_read, a2a_feed_read, http_feed_read, registration_started, scout_started …)
    that the plugin skill calls "aggregate activation and scout health"; it reports usage, not uptime or
    incidents. No StatusPage pointer is emitted.
