Status: IN
Data integrity checking fails in two complementary ways: CRC checksums exclude routing metadata (sequence numbers, page numbers, headers), so corruption in those fields goes undetected; and every reader halts at the first detected CRC failure with no resync capability — meaning both detectable and undetectable corruption are terminal.
incomplete detection + no recovery = both missed and caught corruption are equally fatal
