How the The Browser Line Read-Off gate works
How the Browser Line Read-Off rolls ten checks into one verdict: each check resolves to enforced, trusting the browser, or fine in the browser, and a gate catches server-side code that still decides from a browser value - which is how the sample reads NO LINE.
How the gate works
This tool grades each check in your app on whether the browser could simply bypass it. It reads 10 checks and rolls them into one verdict — the worst, never the average — and then a gate that can only make it worse.
The 10 checks

The verdict bands
Server-side code that decides from a value the browser sent is still a browser-side decision. The code moved; the trust did not. An observation you could not find resolves to the unsafe side — you get no credit for a wall you cannot locate.
In the worked sample it reads NO LINE — Four of ten checks trust the browser, and one of them guards money — so the line does not hold anywhere it counts. Two of those four sit in server-side code and still failed: they decide from a value the browser handed them. Three more are browser-side on purpose and never count against you. The one thing to fix first: C-02, the amount charged at checkout — it runs server-side but decides from a value the browser sent, and it guards money.
Common questions
Can every check look survivable on the How the Browser Line Read-Off gate works and the company still read NO LINE?
Yes. The roll-up takes the worst of 10 checks — never the average — then a worsen-only gate, the Moved-but-still-trusting gate, escalates when trouble clusters. In the worked sample it reads NO LINE because four of ten checks trust the browser, and one of them guards money — so the line does not hold anywhere it counts. Two of those four sit in server-side code and still failed: they decide from a value the browser handed them. Three more are browser-side on purpose and never count against you.
What is a worsen-only gate?
A dispositive rule that can only lower a verdict, never raise it. One fatal flaw overrides an otherwise-set of survivable lines, because a single disqualifying gap shouldn't hide behind an average of the healthy ones. The tool also names the one thing to fix first — here, "C-02, the amount charged at checkout — it runs server-side but decides from a value the browser sent, and it guards money".
Grades how an app is built, never a person. Not a scanner, a penetration test, or a code audit — it reads back what you tell it, using rules you can see.
