# Centralized Spectral ruleset for Elastic OpenAPI specs.
# Consumers do not author rules; changes land here via PR (elastic/docs-eng-team#639).
#
# extends `spectral:oas` fully OFF, then re-enables specific rules by name.
# This is deliberate: it means new rules that Spectral's built-in ruleset adds
# in a future release never silently start applying to consumers.
#
# Two tiers:
#   - error: parses, $refs resolve, conforms to the OAS schema for its version.
#     (invalid-ref and parser failures are resolver-level and always error,
#     regardless of what's enabled below.)
#   - warn: authoring conventions. Kept at warn so existing specs pass
#     as-is; flip a consumer's `fail-on-warn` input to `true` to enforce.
extends: [["spectral:oas", off]]

# Swagger 2.0 forbids braces in `host`, but self-hosted products publish a
# placeholder host on purpose (Elastic Cloud Enterprise: `{{hostname}}`, the
# coordinator the reader installs). Bump.sh accepts it; so do we. Only `host`
# is relaxed, every other oas2-schema check stays at error.
overrides:
  - files: ["**#/host"]
    rules:
      oas2-schema: warn

rules:
  # ---- Core tier (error) ----
  oas2-schema: error
  oas3-schema: error # covers both 3.0.x and 3.1.0; Spectral dispatches on detected version

  # ---- Convention tier (warn) — built-in spectral:oas rules, re-enabled ----
  operation-operationId: warn
  info-description: warn
  oas3-api-servers: warn # 3.x only; Swagger 2.0 has no `servers` equivalent
  operation-description: warn
  operation-tags: warn
  operation-tag-defined: warn

  # ---- Convention tier (warn) — custom Elastic rules ----
  #
  # None enabled yet. The rules below are examples sketched from the
  # conventions analysis in elastic/docs-eng-team#639, but those conventions
  # (operationId casing, security scheme naming, the x-state shape) aren't
  # agreed yet across consumer teams. Uncomment and land via PR once a
  # convention is actually adopted — don't enforce contested decisions here
  # ahead of agreement.
