THE GATE
Nothing leaves unverified.
The Gate is the checkpoint between drafting and filing. Every citation is checked twice: once that it's good law, once that it says what you claim it says.

Layer one: good law
Every authority is checked for validity and subsequent history before it leaves the building. Overruled, superseded, or questioned. You know before the court does.
Layer two: says what you claim
The proposition you cite it for is checked against what the authority actually holds. This is the failure mode behind the sanctions list. Caught at the door, every time, on every draft.
The audit dashboard
Every AI-assisted output in the firm, logged: who ran it, what checked it, what shipped. Rule 5.3 supervision as a control you can show, not a memo you hope someone read.
Anything drafted from the Proof Engine passes the Gate on the way out. The strip proves the case; the Gate protects the license.
What it doesn't do
The Gate verifies citations and quotations against their sources. It doesn't argue your motion, and passing it isn't legal advice. It's the floor: the part that should never have been in question.
File like it's been checked twice. Because it has.
No credit card. No sales call required.
