  title: API Evangelist enhancements for the Engrail Therapeutics Site Content API
  version: 1.0.0
extends: openapi/engrail-therapeutics-content-openapi.yml
x-generated: '2026-08-01'
x-method: generated
x-source: >-
  API Evangelist enrichment pipeline. Captures the derivation provenance, the runtime conventions
  observed live, and the agent-surface cross-links as x- extensions rather than mutating the derived
  specification.

  update:
    x-apievangelist-enriched: '2026-08-01'
    x-apievangelist-provenance: >-
      DERIVED, not provider-authored. Engrail Therapeutics publishes no OpenAPI. This contract is a
      mechanical translation of the WordPress REST route-discovery document the host serves at
      https://www.engrail.com/wp-json/ .
    x-apievangelist-surface-class: corporate-site-content-api
    x-apievangelist-notes: >-
      Engrail is a clinical-stage precision-neuroscience company. It ships no product or developer
      API. Consumers should treat this surface as read-only site content, not as a data product.

  update:
    x-rate-limits:
      signalled: false
      note: >-
        No RateLimit-* or Retry-After headers were observed and no policy is published. Clients
        should apply conservative self-imposed pacing.
    x-idempotency:
      supported: false
      note: All modelled operations are safe GETs; no idempotency-key contract exists.
- target: $.servers
  update:
    x-alternate-hosts:
    - https://engrail.com/wp-json
    x-note: The apex serves the same routes as www; www is canonical.
- target: $.components.schemas.Error
  update:
    x-observed: '2026-08-01'
    x-not-rfc9457: >-
      This is the WordPress REST envelope, not RFC 9457 Problem Details. Agents must read data.status
      rather than relying on a `type` URI.
