description: Versioning and lifecycle posture of Linsy's agent-commerce surface. Linsy does not run a
  developer program, so there is no published deprecation policy, SLA, status page or changelog. What is
  versioned — and versioned explicitly — is the Universal Commerce Protocol contract, negotiated by date
  through the merchant profile.
versioning:
  style: dated protocol version
  current: '2026-04-08'
  label: latest stable
  supported:
  - version: '2026-04-08'
    profile: https://linsy-home.myshopify.com/.well-known/ucp/2026-04-08
    status: current
  - version: '2026-01-23'
    profile: https://linsy-home.myshopify.com/.well-known/ucp/2026-01-23
    status: supported
  discovery: https://www.linsyhome.com/.well-known/ucp
  negotiation: Capability entries declare requires.protocol.min, so an agent selects a version by
    reading the merchant profile before calling the MCP endpoint.
deprecation_policy:
  published: false
  sunset_header: not documented
  deprecation_header: not documented
sla:
  published: false
status_page:
  published: false
  note: No Linsy-operated status page found; the underlying platform status is Shopify's.
changelog:
  published: false
  note: No dated API changelog on either Linsy host. Protocol change is observable only through the
    supported_versions map in the UCP profile.
product_lifecycle:
  founded: 2007
  note: 'Product-side commitments published on the storefront rather than an API lifecycle: 3-year
    warranty and replaceable covers, per the brand story page.'
