History
Immutable event ledgers preserving the exact temporal ordering of past states.
Definition & Bounds
History is the immutable record of every state transition that has ever occurred. Unlike transient state, history can never be mutated—only appended to.
Why It Matters
Systems that discard history lose the ability to audit past decisions, debug emergent bugs, replay state transitions, or build event-driven analytical models.
Axiomatic Constraints
- 01.History is append-only and strictly ordered by monotonic time.
- 02.Current state can always be recomputed by replaying history.
- 03.Tamper-evident ledgers guarantee historical integrity across parties.
- 04.Compaction strategies manage history growth without losing lineage.
