notes: 'Cross-cutting request/response semantics could not be derived: Everstream Analytics
  publishes no OpenAPI and no public API reference. Every field below is either an
  observed fact or an explicit "not published". Nothing is inferred. In particular
  there is NO evidence of an idempotency contract, so no Idempotency pointer is wired
  in apis.yml.'
authentication:
  style: not published for the platform API
  application_layer: OAuth 2.0 authorization code + PKCE via Auth0 (riskpulse-prod tenant),
    audience https://maglev-prod/api
  detail: authentication/everstream-analytics-authentication.yml
idempotency:
  supported: unknown
  documented: false
  header: null
  evidence: No idempotency key, header, or retry-safety statement appears on any public
    Everstream page. Not claimed, not observed.
pagination:
  documented: false
  style: null
versioning:
  documented: false
  scheme: null
  evidence: No version segment, header, or date-based version scheme is published. The
    integration host int.us1.apps.everstream.ai returns 404 for /v1 and /api.
field_expansion:
  documented: false
metadata:
  documented: false
request_tracing:
  documented: false
  observed: 'AWS API Gateway emits an `apigw-requestid` response header on int.us1.apps.everstream.ai
    (observed on a 404). This is infrastructure behaviour, not a documented tracing
    contract.'
error_envelope:
  documented: false
  observed: 'The integration host returns `{"message":"Not Found"}` on an unrouted
    path — the AWS API Gateway default, not a documented error envelope. Not RFC 9457
    problem+json.'

  documented: false
