AI Engineering/Phase 14/Lesson 38

Verification Gates

The agent does not get to mark its own work as done. A verification gate reads the scope contract, the feedback log, the rule report, and the diff, and answers a single question: is this task actually complete? If the gate says no, the task is not done, no matter what the chat says.

Prerequisites: Phase 14 · 33 (Rules), Phase 14 · 36 (Scope), Phase 14 · 37 (Feedback)

#Learning Objectives

Define a verification gate as a deterministic function over workbench artifacts.
Combine rule report, scope report, feedback records, and diff into a single verdict.
Emit a verification_report.json the reviewer agent and CI can both read.
Refuse to advance a task on any block-severity failure, without exception.
