Integrity Properties
Append-only

Every state transition appended to an immutable event ledger. Records are never edited in place.

Time-sequenced

All events timestamped and sequenced at ingestion. Temporal order preserved and reviewable.

Independently reviewable

Evidence bundles support independent review without reliance on the fund's own reporting.

Replayable from recorded event history

Full audit replay from event log to any historical state, producing consistent, reproducible results.
