What the harness does

The checking step is the part nobody sells you.

Verify

Every case, statute and citation checked to existing, current and on point — then labelled authority or reasoning.

Source

Every clause traced to the precedent, statute or instruction it came from, with a change log.

Sign off

A named lawyer approves; the client-facing statement carries the numbers. The AI never signs.

The four-file harness

Plain text. No code. Runs in your account.

Rules, a test set with traps, a one-page checklist and a provenance ledger — the system that makes an AI-assisted draft defensible before it leaves the firm.
