  Coinshift publishes no HTTP API, so the API-side standards below are all recorded as non-conforming
  by absence rather than by defect. The standards Coinshift genuinely conforms to are onchain token
  standards, which its own documentation states explicitly.
standards:
  - id: erc-20
    conforms: true
    evidence: >-
      csUSDL and csUSDC are ERC-20 tokens on Ethereum (csUSDL: Coinshift USDL, 18 decimals,
      0xbEeFc011e94f43b8B7b455eBaB290C7Ab4E216f1) — docs.coinshift.xyz token specification pages.
  - id: erc-4626
    conforms: true
    evidence: >-
      Documentation states "ERC4626 is an extension of ERC20 that proposes a standard interface for
      token vaults" and describes csUSDL as the ERC-4626 receipt token of the Coinshift USDL Morpho Vault.
  - id: openapi
    conforms: false
    evidence: >-
      No OpenAPI/Swagger document found. Probed /openapi.json, /openapi.yaml, /swagger.json,
      /v1/openapi.json, /api-docs, /docs, /redoc, /rapidoc on docs.coinshift.xyz and on the
      application backend uspc-prod.up.railway.app — 404 on every path.
  - id: graphql
    conforms: false
    evidence: POST introspection to uspc-prod.up.railway.app/graphql and /api/graphql returned 404 NOT_FOUND.
  - id: asyncapi
    conforms: false
    evidence: No event, streaming or webhook surface documented anywhere in docs.coinshift.xyz.
  - id: mcp
    conforms: false
    evidence: tools/list POST to uspc-prod.up.railway.app/mcp returned 404 NOT_FOUND; no hosted MCP server advertised.
  - id: a2a
    conforms: false
    evidence: >-
      /.well-known/agent-card.json and /.well-known/agent.json return the SPA HTML shell on
      www.coinshift.xyz, app.coinshift.xyz and coinshift.global (soft 200, not an AgentCard),
      and 404 on docs.coinshift.xyz and uspc-prod.up.railway.app.
  - id: oauth2
    conforms: false
    evidence: >-
      /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource return 404
      on docs.coinshift.xyz and uspc-prod.up.railway.app. Application sign-in is wallet-based
      (Reown/WalletConnect), not OAuth.
  - id: oidc-discovery
    conforms: false
    evidence: /.well-known/openid-configuration returns 404 on docs.coinshift.xyz.
  - id: rfc9116-security-txt
    conforms: false
    evidence: >-
      /.well-known/security.txt returns 404 on docs.coinshift.xyz and the SPA HTML shell (soft 200)
      on www.coinshift.xyz.
  - id: rfc9457-problem-details
    conforms: false
    evidence: >-
      The undocumented application backend returns a bespoke envelope
      {"success":false,"error":{"code":"NOT_FOUND","message":"Route not found"}} with
      content-type application/json — not application/problem+json.
  - id: llms-txt
    conforms: true
    evidence: >-
      docs.coinshift.xyz/llms.txt returns 200 text/markdown with a complete, link-per-page index of
      the documentation, and the docs themselves cite it as the canonical "Documentation Index".
