      The Contracts (smart contract) Language API is separately versioned; v4 was released with
      Vault Core 4.5 (2022). v3 was marked deprecated and, per the partner write-up, support is
      removed by the Vault Core 7.x release.

  practice: >-
    Rolling major-release deprecation — items marked deprecated in one annual major release are
    removed in the following one (evidence: partner write-up above). No public, provider-authored
    deprecation policy page exists, and no Sunset/Deprecation header behaviour could be observed
    because there is no anonymously reachable API host.

  x-note: >-
    Vault is delivered either SaaS or bank-hosted; SLAs are contractual and not published. The
    TM Sandbox terms explicitly disclaim any uptime or support guarantee
    (https://www.thoughtmachine.net/api-terms).

changelog_x-note: >-
  No public dated changelog or release-notes feed. Product news is published as marketing posts
  at https://www.thoughtmachine.net/newsroom and https://www.thoughtmachine.net/blog, which are
  not a versioned changelog.

x-note: >-
  No StatusPage or Deprecation pointer is wired in apis.yml because neither a public status page
  nor a provider-published deprecation policy exists. Absence recorded, not fabricated.
