HTTP status comes from `mapErrorStatus` at\n *   the route's `unwrapResult` site — handlers don't know about\n *   statuses.\n * - Catches everything else, logs server-side, returns a 500-class\n *   code without leaking `error.message`.\n *\n * Reserved-slug + identifier validation runs at the zod layer (see\n * `schemas/byline-fields.ts`); the registry repeats it for defence in\n * depth (non-HTTP callers).
