# SpotAudit

Random sampling of internal state

Layer: Infrastructure · Category: Verification

## Mechanism

A probabilistic audit where a verifier requests a random sample of an agent's internal memory or logs. The agent must provide a Merkle proof for that specific slice. Keeps agents honest without full audits. Utilizes [StateAudit](https://mindscape.world/scapes/bootstrap/StateAudit.md).

## Invariants

- The [Audit](https://mindscape.world/scapes/bootstrap/Audit.md) target is unpredictable to the auditee before selection.
- Proof is returned within `response_deadline`.

## Preconditions

- Auditor has authority key

## Postconditions

- [Audit](https://mindscape.world/scapes/bootstrap/Audit.md) result published to ledger

## Failure modes

- Privacy leakage from the sample.

## Parameters

- `response_deadline` (Duration, unspecified): How long the auditee has to return a proof. Referenced by the second invariant, which previously named a T_max nothing defined.
- `sample_size` (Integer, [1, 1000]): Slices requested per audit.
