  L-Nutra publishes no versioning policy, no deprecation policy, no SLA, no status page and no
  changelog of its own. The only lifecycle signal on the whole surface is the UCP protocol version
  it negotiates, which is inherited from the Shopify platform rather than authored by L-Nutra.
versioning:
  style: dated protocol version
  current: '2026-04-08'
  supported:
  - version: '2026-04-08'
    profile: https://prolon-fmd-2020.myshopify.com/.well-known/ucp/2026-04-08
  - version: '2026-01-23'
    profile: https://prolon-fmd-2020.myshopify.com/.well-known/ucp/2026-01-23
  negotiation: >-
    Discovery at /.well-known/ucp lists a pinned profile per supported version; the served version
    is echoed on every response as x-shopify-ucp-mcp-api-version.
  authored_by: Shopify / ucp.dev, not L-Nutra.
deprecation_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.
    The previous protocol version 2026-01-23 is still served with no stated removal date.
status_page:
  published: false
  note: >-
    L-Nutra runs no status page. The storefronts are hosted on Shopify, whose status page at
    status.shopify.com is a platform page, not an L-Nutra one, so no StatusPage pointer is emitted.
sla:
  published: false
changelog:
  published: false
  note: No dated changelog exists for the storefronts or their agent surface.

  The corporate site l-nutra.com returned HTTP 500 for every path requested on 2026-08-23,
  including its home page (WordPress fatal error behind Flywheel/5.1.0). It is recorded here as a
  live operational defect, not as a lifecycle policy.
