  // global_fetch_strictly_public is NECESSARY BUT NOT SUFFICIENT for CIMD
  // (Client ID Metadata Documents). workers-oauth-provider gates it on BOTH
  // conditions:
  //
  //   client_id_metadata_document_supported:
  //     !!options.clientIdMetadataDocumentEnabled && hasGlobalFetchStrictlyPublic()
  //
  // This flag satisfies the second; src/index.ts supplies the first. Both are
  // required — dropping either one does NOT merely stop advertising CIMD, it
  // makes a URL client_id fall back to a bare KV lookup, so Claude Code
  // resolves only while a stale `client:` record happens to survive in KV and
  // returns "invalid_request: Invalid client_id" once it doesn't.
  //
  // That is not hypothetical: the flag sat here for months without the
  // provider option, and deploy.yml's smoke test flipped 200 -> 400 across two
  // deploys of identical code before it was found. Do not remove either half.
