Proof Gates are the layer that asks whether an action has enough evidence to move. They are designed to spot weak proof, missing proof, risky proof and overconfident claims.
A proof gate does not need every action to be blocked. It gives the system more choices: allow, review, challenge, hold or block. That is what makes the system practical. Safe actions can keep moving. Unclear actions can slow down. Dangerous actions can stop.
Payment release can require completion evidence, dispute checks or cooling logic.
Builds can require staging, content depth, manifest, safety review and rollback.
Trust badges and proof pages should be backed by authorised build state and safe public evidence.
