versioning:
  scheme: uri-path-namespace
  current: wp/v2
  docs: null
  note: >-
    Version is carried by the WordPress REST namespace segment. TwinStrand does not version an API
    of its own — the namespace version tracks WordPress core (site reports WordPress 7.0.2).
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  note: >-
    No deprecation or sunset policy is published, no RFC 8594 Sunset/Deprecation header was
    observed on any probed response, and no operation in the derived OpenAPI is marked deprecated.
    No Deprecation pointer wired.
sla:
  url: null
  uptime_target: null
  note: No SLA, uptime commitment or support tier is published for any surface.
status_page:
  url: null
  probed:
  - {url: 'https://status.twinstrandbio.com/', result: DNS does not resolve (NXDOMAIN)}
  - {url: 'https://twinstrandbio.com/status/', result: 404}
  note: >-
    No status page exists on any TwinStrand host. No StatusPage pointer wired — asserting one
    would be fabrication.
changelog:
  url: null
  probed:
  - {url: 'https://twinstrandbio.com/changelog/', result: 404}
  - {url: 'https://twinstrandbio.com/company/news/', result: '200 — corporate newsroom (27 releases), not an API changelog'}
  note: >-
    TwinStrand publishes no changelog or release notes for any API or for the DuplexSeq software.
    The newsroom is wired as News, not ChangeLog. No ChangeLog pointer wired.
support:
  contact_page: null
  developer_support: null
  probed:
  - {url: 'https://twinstrandbio.com/contact/', result: 404}
  - {url: 'https://twinstrandbio.com/careers/', result: '404 (redirects to ?page_id=7644, which also 404s)'}
  note: >-
    There is no standalone contact page in the site sitemap and no developer support channel,
    forum, community, Slack/Discord or issue tracker for any API. Contact happens through
    HubSpot forms embedded in product pages. No Support pointer wired.
blog:
  url: null
  note: >-
    The `post` collection is registered but empty (X-WP-Total: 0) and https://twinstrandbio.com/feed/
    returns 200 with zero <item> elements. There is no blog. The per-post-type feed at
    /company/news/feed/ returns 403. No Blog or BlogRSS pointer wired.
developer_surface_probes:
  note: >-
    Probed 2026-08-05 for any developer-facing surface. TwinStrand publishes none: no developer
    portal, no documentation site, no API reference, no quickstart, no API pricing and no API
    sign-up. api., docs., developer., developers., support., portal. and app.twinstrandbio.com all
    fail to resolve. No pointer was wired for any of these — the pages do not exist.
  postman:
    wired: false
    finding: No public Postman workspace or collection attributable to TwinStrand Biosciences was found.
product_lifecycle:
  note: >-
    Not an API lifecycle, but material to anyone reading this profile: the commercial surface has
    moved. Recorded from TwinStrand's own newsroom.

      https://scantox.com/twinstrand-mutagenesis-assay/ (200, redirects to the Scantox
      DuplexSeq Mutagenesis Assays service page). Any future machine-readable surface for that
      assay will belong to Scantox, not TwinStrand.
