  Additive only. Every action below records something Inrupt publishes elsewhere (its service
  reference, its hosted deployment, its RFC claims) that the spec itself omits. The original document
  at https://notification.inrupt.com/openapi.yaml is never mutated.

      The ESS Notification Delivery Service lets an authorized agent subscribe to change events on Pod
      resources and on Access Requests and Grants, and receive them as RFC 9421-signed webhook POSTs at
      a remote HTTPS endpoint. Two scopes exist - /subscriptions for authenticated users (delivery is
      further filtered by the subscriber's own authorization on the resource) and /system/subscriptions
      for allow-listed system managers whose legal basis for processing is contract.

    Add a servers block. The published document declares no servers[], so a tool cannot resolve a
    request URL from the spec alone. ESS is customer-deployed, so the host is templated, with Inrupt's
    own hosted PodSpaces deployment as the default.

      pagination: page/pageSize with RFC 8288 Link rel=next / rel=prev
- target: $.paths['/subscriptions'].get
  description: Document the pagination contract, which is described in the service reference but not in the spec.
  update:
    x-pagination:
      style: page-number
      params: [page, pageSize]
      page_size_max: 100

- target: $.paths['/subscriptions'].post
  description: Record the event-type enumeration accepted in the request body's type[] array.
  update:
    x-event-types:
    - AccessRequestPending
    - AccessRequestDenied
    - AccessGrantIssued
    - AccessGrantRevoked
    - AccessGrantExpired
    - ResourceCreated

    - ResourceDeleted
    - ContainerCreated

    - ContainerDeleted
    x-idempotency: >-
      None. Repeating this request creates an additional subscription; there is no client-supplied
      request key and no server-side deduplication.
    x-reversibility:
      operation: removeSubscription
      window: any time while the subscription exists
- target: $.paths['/subscriptions/{identifier}'].delete
  description: Mark the reversal relationship explicitly for agent tooling.
  update:
    x-reverses: createSubscription
- target: $.components.schemas.Subscription.properties.storage
  description: Record the ESS 3.0 canonical-URI requirement, which is a correctness trap for clients.
  update:
    x-required-uri-form: >-
      Must be the canonical resource URI ({storage-id}/sc/{resource-id}), not the path URI
      ({storage-id}/sp/{resource-path}), so the subscription survives a deployment domain change.

  description: Describe how the bearer token is actually obtained.
  update:
    description: >-
      A Solid-OIDC access token, or an ESS Access Token obtained by RFC 8693 token exchange against
      https://platform.{essDomain}/access/token. Default ESS Access Token TTL is 5 minutes; treat 401
      as routine and re-exchange.
