  Bulletproof publishes no versioning policy, no deprecation policy, no SLA and no status
  page of its own. Everything below was read out of the live surface on 2026-08-08. The
  version calendar and the deprecation markers are real and machine-readable; the policy
  documents behind them are Shopify's, not Bulletproof's, and are therefore recorded as
  absent for this provider.

    GraphQL @deprecated directives carried in the schema itself — 54 deprecated fields
    across 40 types, each with a machine-readable deprecationReason naming the
    replacement field. This is the only deprecation signal Bulletproof exposes.
  deprecated_field_count: 54
  examples:
  - field: Cart.estimatedCost
    reason: Use `cost` instead.
  - field: Cart.discountAllocations
    reason: 'Use `cart.lines[].discountAllocations(lineLevelOnly: false)` instead.'
  - field: Article.author
    reason: Use `authorV2` instead.
  - field: BaseCartLine.estimatedCost
    reason: Use `cost` instead.
  - field: CartBuyerIdentity.deliveryAddressPreferences
    reason: Use `cart.delivery` instead.
  - field: AppliedGiftCard.balanceV2
    reason: Use `balance` instead.

  note: >-
    No first-party status page. The underlying platform status pages (status.shopify.com,
    wpenginestatus.com) are not Bulletproof properties and are not recorded as such.

  note: >-
    No dated API changelog on any Bulletproof host. The editorial blog at
    https://www.bulletproof.com/blog/ is product/nutrition content, not release notes.
