 * render or the validation worker) so the encode uses the matching
 * client-reference manifest and captures the live `Error` objects with their
 * stacks and digests. The error codes ride along in a side-channel `Map`
 * because React doesn't revive `__NEXT_ERROR_CODE` during RSC deserialization;
 * RSC preserves object identity, so the revived map keys reference the same
 * errors.
