note: >-
  Neither OpenAPI declares an oauth2 security scheme (derive-oauth-scopes.py found 0 oauth2 schemes), so this
  file is built from the OAuth discovery documents the provider serves: the RFC 9728 protected-resource
  metadata on app.clawspan.cloud (resource = the MCP endpoint) and the RFC 8414 / OIDC metadata on the
  authorization server it names, clerk.clawspan.cloud. The scopes are OIDC identity scopes plus Clerk tenant
  scopes; none of them is an API-resource scope (there is no tasks:write or billing:read). Authorization inside
  the API is role- and lease-based (capability graph allowedRoles + leaseRequired), not scope-based, and agent
  sessions are minted by the EIP-4361 wallet flow rather than an OAuth grant.
