# Proof Ledger

Record commands, exit results, and supporting files as durable proof artifacts.

Type: Execution evidence toolkit

Availability: Public source package

## The work

A remembered terminal result is difficult for another reviewer to inspect later.

A local runner and ledger that retain command evidence, failed runs, and reviewer-facing proof packets.

## Where it stands

The ledger records local executions. It does not independently establish production behavior or certify claims.
