Status: IN
The system has no defense-in-depth against data corruption: input validation is systematically absent at API boundaries (malformed data enters freely), and corruption is terminal across all readers with no resync capability (corrupted data can never be recovered) — the system is maximally permeable to corruption entry and maximally fragile to corruption presence.
Two depth-1 conclusions cover opposite ends of the data lifecycle (entry vs detection) and both show total absence of protection, making corruption a one-way ratchet
