# Audit trail and data disclosure

The immutable history of what happened, and the verifiable ledger of third-party access.

## In brief

- **Audit history:** Append-only, separate database
- **Third-party access:** Tamper-evident ledger

## The audit history

Every application has a dedicated audit database recording what changed, who changed it, and when — kept separate from live data so operational activity can't disturb the record.

## Disclosure ledger for extensions

When a marketplace extension accesses tenant data, that access is written to a hash-chained ledger: each entry cryptographically commits to everything before it, so the record cannot be silently altered or trimmed after the fact. The exact code identity of the extension is snapshotted at invocation, so the ledger reflects precisely what ran. Tenants can verify their own ledger independently.
