Verification Gate

Overview

A pre-completion gate that converts the assertion "this is done" into evidence: the test output, the command run, the behavioral observation. The skill exists because "done" is a self-reported state and self-reports are wrong roughly half the time on real changes. The gate is short — five minutes — but it catches the class of mistake where an engineer claims a fix works after only running tests in their IDE, only verifying happy-path, only checking a single environment. This is the load-bearing skill of v4: every other skill funnels through it before its work is called done.
