description: >-
  Lifecycle posture for the only machine-readable surface Denbury Inc. operates. There is no
  published versioning policy, no deprecation policy, no SLA and no status page, because there is no
  developer program to attach one to. What there IS, and what a consumer of this surface actually
  needs to weigh, is corporate lifecycle risk: the company was acquired and deregistered, and the
  site is maintained as a legacy property.
versioning:
  policy_published: false
  scheme: path-namespace
  current: wp/v2
  detail: >-
    Versioning is whatever WordPress core ships. The namespace in the path is the version; Denbury
    neither pins it nor announces changes to it. A WordPress core upgrade can add, alter or retire
    routes on this host with no notice to any consumer.

deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  detail: >-
    No Sunset or Deprecation response header was returned on any observed request, and no deprecation

  deprecated_operations: []
sla:
  published: false
  detail: No service level agreement, uptime commitment or support commitment is published.
status_page:
  present: false
  url: null
  detail: >-
    No status page exists. status.denbury.com does not resolve and no status link appears anywhere on
    www.denbury.com. No StatusPage pointer is emitted.
changelog:
  present: false
  detail: >-
    No changelog, release notes or dated update feed is published for the site or the API. The blog
    surface is empty — /wp/v2/posts returns X-WP-Total: 0 — and https://www.denbury.com/feed/ returns
    HTTP 500. No ChangeLog pointer is emitted.
support:
  url: https://www.denbury.com/contact-us/
  detail: General corporate contact form and info@denbury.com. There is no developer support channel.
corporate_lifecycle:
  status: acquired-subsidiary
  detail: >-
    ExxonMobil completed its acquisition of Denbury on 2023-11-02. Denbury filed a Form 15-12G on
    2023-11-22 to deregister its securities and has filed nothing with the SEC since (last filing of
    any kind: SC 13G/A, 2024-02-07). The corporate site remains live and is maintained — the footer
    reads "© COPYRIGHT 2026 DENBURY INC." and the homepage carries a banner directing visitors to
    ExxonMobil.com — but it is a legacy property inside ExxonMobil's Low Carbon Solutions business.
  evidence:
  - url: https://data.sec.gov/submissions/CIK0000945764.json
    status: 200
    note: 'DENBURY INC — form 15-12G filed 2023-11-22; no filings after 2024-02-07'

  - url: https://www.denbury.com/
    status: 200
    note: 'Live WordPress site; banner: "Denbury is now a part of ExxonMobil."'
  consumer_risk: >-
    Any integration against www.denbury.com carries the risk that the acquirer retires the property.
    The content is historical corporate material, not an operating data feed.
site_collapse:
  observed: '2026-09-06'
  detail: >-
    The human website has been collapsed to a handful of legal and contact pages while the REST API
    still serves the full corporate corpus. Every one of the 48 published pages was fetched at the
    `link` its own API record advertises: 41 of the 48 answer HTTP 200 but land on the homepage
    (https://www.denbury.com/), one 301s off-site to jobs.denbury.com, one lands on a spreadsheet
    download, and only 5 resolve to themselves. The full HTML bodies of the redirected pages remain
    intact and anonymously readable through /wp/v2/pages/{id} — page 31 "Carbon Solutions" returns
    17,650 characters of content.rendered, page 1170 "Managing our Carbon Footprint" returns 17,233.
  consequence: >-
    For 41 pages of Denbury's carbon-solutions, EOR, pipeline-network and sustainability material,
    the REST API is now the only public route to the content. That is a lifecycle signal, not a
    feature: the site is being wound down around an API nobody switched off.
