  endpoint), the BasicAuth securityScheme in the tec/v1 contract at https://hpsf.io/wp-json/tec/v1/docs,

- name: BasicAuth
  type: http
  scheme: basic
  header: 'Authorization: Basic <base64 username:application-password>'
  declared_in: openapi/hpsf-tec-events-api-openapi.yml
  mechanism: WordPress Application Passwords
  authorization_endpoint: https://hpsf.io/wp-admin/authorize-application.php
  authorization_endpoint_source: >-
    Declared by the host itself in the authentication block of https://hpsf.io/wp-json/
  applies_to: All POST/PUT/PATCH/DELETE operations across tribe/events/v1 and tec/v1.
  public_onboarding: false
  note: >-
    Application Passwords are issued from inside the WordPress admin to an existing site user. HPSF
    publishes no process for a third party to obtain one, so the write half of both contracts is
    documented but unreachable from outside the foundation's own web team.
gated_surfaces:
- namespace: wp-abilities/v1
  status: 401
  code: rest_forbidden
  note: >-
    The WordPress Abilities registry is installed and registered on this host. An anonymous GET of
    /wp-json/wp-abilities/v1/abilities returns 401 - the ability list, which is the closest thing this
    host has to a machine-callable tool catalog, requires an authenticated WordPress user.
- namespace: tec/v1
  status: 400
  code: missing_experimental_endpoint_acknowledgement
  note: >-
    Not an authentication gate. The namespace is fenced behind an undocumented acknowledgement header
    for experimental endpoints, and rejects anonymous callers before any credential is considered.
- namespaces: [activity-log/v1, objectcache/v1, liquidweb/harbor/v1, regenerate-thumbnails/v1, wp-site-health/v1, tec/v2/onboarding, tribe/event-aggregator/v1, tribe/zapier/v1, tribe/power-automate/v1]
  note: >-
    Site-administration and integration plugin routes, all permission-gated to a logged-in WordPress
    administrator. Present in the route index; not a public API surface.
absent:
  api_key_header: null
  oauth_scopes: null
  note: >-
    scopes/ is deliberately not written. There is no oauth2 securityScheme in either contract and no
    OAuth documented anywhere, so an OAuthScopes artifact would be an empty claim.
