note: The Canada Energy Regulator publishes no API lifecycle policy of any kind — no versioning statement, no deprecation
  policy, no sunset commitment, no SLA and no status page. Nothing below is a policy the CER has stated; it is the
  version surface each upstream product happens to expose, plus the dataset update cadences the CER declares in its
  own CKAN metadata, which are the closest thing to a published freshness commitment it makes.
versioning:
  policy_published: false
  scheme: per upstream product, not CER-controlled
  surfaces:
  - surface: CER ArcGIS Online feature services
    version: currentVersion 12
    scheme: vendor build number in the service descriptor
  - surface: CER Assessments MapServer (Federal Geospatial Platform)
    version: currentVersion 10.81
    scheme: vendor build number
  - surface: OGC WMS
    version: 1.3.0
    scheme: required version= query parameter
  - surface: Open Government Portal CKAN
    version: v3
    scheme: URI path — /data/api/3/action
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  note: No RFC 8594 Sunset or Deprecation header was observed and no deprecation policy page exists. Layer names carry
    the de facto versioning instead — Incident_Data_English_20191007_View pins a 2019-10-07 extract, and CER_Pipeline_Systems_WGS84_view
    sits beside CER_Pipeline_Systems_WGS84_WM_v with the same 28 features in a different projection. Nothing tells
    a client which is canonical or when either retires.
stale_or_provisional_surfaces:
- service: Terminal_test
  note: Name declares itself a test service; 13 features, published anonymously alongside production layers.
- service: tmp_mid_view
  note: '"tmp" service holding 3,007 pipeline segment features. No statement of status.'
- service: survey123_e293d5b8f8e54fcab496bebabc814db6_fieldworker
  count: 0
  note: An empty Survey123 fieldworker layer left public. Zero features on 2026-07-27.
- service: Oil_and_Gas_Resource_Area_7344b
  note: Byte-identical field set and feature count (3) to Oil_and_Gas_Resource_Area. An unretired duplicate.
- service: Incident_Data_English_20191007_View
  note: The incident layer is frozen at a 2019-10-07 extract while the CKAN Incidents dataset continues to update.
    The geospatial and tabular views of the same regulatory record have diverged.
sla:
  url: null
  uptime_target: null
  published: false
status_page: null
status_page_note: The CER operates no status page. The infrastructure serving its only self-operated API is Esri ArcGIS
  Online, whose status page (https://status.arcgis.com/) covers the vendor platform rather than the CER service, and
  the CKAN surface is Treasury Board infrastructure. Neither is a CER commitment, so no StatusPage pointer is emitted.
upstream_status_pages:
- operator: Esri
  url: https://status.arcgis.com/
  covers: ArcGIS Online, which hosts the 23 CER feature services
data_freshness_declared:
  source: CKAN "frequency" field across the 83 CER datasets, 2026-07-27

  note: The CER replaced the NEB under the Canadian Energy Regulator Act in 2019. The ArcGIS Online portal is still
    hosted at neb-gis.maps.arcgis.com and the predecessor GitHub identity NEBGitHub still carries 5 repositories.
