Integrity Properties
⬡Append-only

Every state transition appended to the 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.

⟳Point-in-time reconstruction

Each snapshot stores the positions, balances, limits and breaches it was computed from, so any past risk state can be read back exactly as it was recorded.
