Watched repositories

Public repositories we audit and re-audit, each with the evidence label that produced its number. Audited the same way as anything you paste on the home page: a clean clone, the documented path, the same gates.

Shape

Repositories published by Vercel. They are here because auditing the platform we are built on is the honest test of the instrument: if it only ever finds fault elsewhere, it is not measuring anything. The FAILs stay on the board. These are not rankings and nothing here sorts. We tried ordering them by time to first value and our own data killed it: three runs of one commit timed 87s, 49s and 50s — a wider spread than the score we had rejected for moving — because the planner proposes a different journey each time. (Those three pre-date the engine that fixed how we measure the span.) The times below are readings, not places. Compare within one shape: a CLI reaches first value differently from an SDK.

Gates read passed / fired / unverified over the seven this engine decides. A re-run needs a signed-in account and counts against your daily audits; an unchanged commit returns the cached report instead of running again. How the score is produced.
