note: |
  Landgate publishes no API versioning policy, no deprecation policy, no SLA for the public
  data services and no status page. What it does publish is a dated Customer Information
  Bulletin (CIB) stream that carries service changes, fee changes and outage notices — that
  is the closest thing to release notes on this estate and it is captured in
  changelog/landgate-changelog.yml.
versioning:
  policy_published: false
  surfaces:
    - surface: SLIP Public Services (ArcGIS REST)
      scheme: server-version-in-payload
      current: '12.1'
      evidence:
        url: https://public-services.slip.wa.gov.au/public/rest/info?f=json
        status: 200
        probed: '2026-07-26'
        body: '{"fullVersion":"12.1.0","currentVersion":12.1}'
      risk: the version is not in the URI, so an Esri upgrade changes behaviour under
        unchanged URLs with no consumer-facing version signal.
    - surface: Data WA CKAN Action API
      scheme: uri-path
      current: '3'
      evidence:
        url: https://catalogue.data.wa.gov.au/api/3/action/status_show
        status: 200
        probed: '2026-07-26'
    - surface: SLIP Public OGC Services
      scheme: query-parameter
      current: 'WMS 1.3.0; WFS 2.0.0'
      also_supported: ['WMS 1.1.1', 'WFS 1.1.0']
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  evidence: no Sunset or Deprecation response header was returned by any probed public
    endpoint on 2026-07-26; no deprecation or API-retirement page exists on landgate.wa.gov.au
  historic_precedent: |
    Landgate has retired a whole developer platform before without a published policy: the
    2013-2015 "SLIP Future" platform was built on Google Maps Engine (see the Landgate GitHub
    org repos slip-code-samples, slip-developer-documentation and Sandbox), and disappeared
    with GME. Those repos are still public and still point at googleapis.com endpoints that no
    longer exist. Treat the absence of a deprecation policy as a live integration risk.
sla:

status_page:

  probed:
    - { url: 'https://status.landgate.wa.gov.au/', status: 000, note: does not resolve }
    - { url: 'https://www.landgate.wa.gov.au/system-status', status: 404 }
  note: |
    No status page exists. Outages and scheduled maintenance are announced as news articles in
    the customer news stream (e.g. "Scheduled system outage notification"), which is a
    human-readable channel with no machine-readable feed for service health.
