// Cloudflare returns `result` as a *bare array* of live-input items.
// This surfaces as an untyped `CloudflareHttpError` (status 200,
// statusText "Schema decode failed") thrown by the schema decoder before
// `list()`'s own code runs. It is a deterministic schema mismatch (not an
// entitlement issue), so the live list test is gated until distilled is
// patched. See the JSON report for the exact needed distilled patch.
