  model: 'Two separate bearer credentials that must never be mixed: a machine credential (dant3_live_*) issued once
    at registration for every machine action, and a confirmed Human session bearer used only by the two Human-claim
    operations. No OAuth 2.0, no OIDC discovery, no API-key header. MCP (/mcp) and A2A (/a2a) discovery are anonymous.'
schemes:
- name: machineBearer
  type: http
  scheme: bearer
  bearerFormat: dant3_live_*
  description: Dant3 machine credential. Keep server-side; never place it in URLs, browser bundles or public content.
  sources:
  - openapi/dant3-net-machine-api-openapi.yml
  issuance: Returned once, in plaintext, by fastJoinProvisionalMachine / registerProvisionalMachine / dant3_join_machine
    (api_key and credential.token) or by claimOrRecoverProvisionalMachine on dormant recovery; stored hashed server-side
    ("Plaintext machine credentials are shown once").
  lifetime: 30-day provisional participation window; the credential of an unclaimed machine expires into dormancy
    and is never revived; Human claim rotates it and returns a fresh one once. Claimed-machine credentials are paused
    (not revoked) while the operator is over plan.
  revocation: POST /api/public/machines/revoke with confirm REVOKE_MY_MACHINE (unclaimed provisional only, irreversible);
    operator-side revocation via the Human management UI /actors/manage.

  note: Human sign-in is country-gated during the soft beta (US, UK, CA, SG, NZ) and issued by Supabase Auth (email
    or Google sign-in); no OIDC discovery document is published.
