  note: >-
    No standalone deprecation or sunset policy page was found on signalwire.com/docs on 2026-08-27,
    and neither OpenAPI contract declares a Sunset or Deprecation response header. Deprecation IS
    practised and visible in the artifacts below, but it is not stated as a policy with a notice
    period, so no Deprecation pointer is emitted.

deprecated_surfaces:
- name: SIP Endpoints (Legacy)
  kind: API resource group
  operations: 5
  evidence: >-
    fern/products/apis/apis.yml marks the section with availability deprecated and hidden true; the
    operations remain in openapi/signalwire-rest-openapi.yml under the tag "SIP Endpoints (Legacy)".
    The replacement is SIP Credentials under /api/fabric/resources/sip_endpoints.
- name: Browser SDK v2 and v3
  kind: SDK major version
  evidence: >-
    The docs carry versioned trees for v2, v3 and v4 and a published "Migrate from v3" guide
    (https://signalwire.com/docs/browser-sdk/v4/guides/migrate-from-v3). v4 was at release-candidate
    (@signalwire/js 4.0.0-rc.2) on 2026-07-14.
- name: Agents SDK / Server SDK as separate products
  kind: documentation product
  evidence: >-
    fern/docs.yml comments: "Deprecated: Agents SDK and Server SDK are now part of the unified SDKs
    product above. Their directories are preserved for reference but no longer rendered as products."
- name: Previous-generation language clients
  kind: SDK generation
  evidence: >-
    github.com/signalwire carries signalwire-python-old, signalwire-ruby-old, signalwire-perl-old,
    signalwire-legacy-node, signalwire-legacy-js and signalwire-dotnet-deprecated alongside the 2026
    port matrix (signalwire-python, -typescript, -go, -ruby, -perl, -java, -cpp, -php, -dotnet,
    -rust). The naming is the deprecation signal; no dated end-of-life notice was found.
- name: signalwire/rest-apis (Postman/Bruno collections repo)
  kind: repository
  evidence: >-
    Repo README: "this manually maintained repo will be archived" — superseded by the official
    Postman workspace linked from https://signalwire.com/docs/apis#try-it-in-postman.
