No compliance system in the world — not Refinitiv World-Check, not LexisNexis Bridger, not ComplyAdvantage, not NICE Actimize — analyses whether two norms from different jurisdictions are in a structural constitutional conflict that makes a transaction principally impossible.
They check lists. They check rules. They do not check whether the legal system itself contradicts itself.
This is not academic. It has material consequences for every institution operating across US and EU jurisdictions simultaneously. Every day, institutions execute transactions that are HARD_BLOCKED under primary law — and no existing system flags it.
Gate 0 is the first system in production to encode this check. When a transaction falls into a constitutional collision field, Gate 0 issues a signed, Merkle-chained receipt before the transaction executes — documenting the specific collision, its legal basis, and the moment of detection.
