Summary / The 27 components

22 Independent reviewer (critic)

A second process that challenges a candidate, with no self-grading.

Latest—not scored
Baseline— 
Live use—last 7 days

Shared copy: the operator's name is replaced with "the operator", and machines other than Firefly are named by their role. Nothing else is changed.

What is built now

A REVIEW state in the driver's graph, switched off. The reviews table is empty.

What is missing

The blinded review packet, the critic call, falsification routed to real tests, and the single send-back to REPAIR (arm h7).

Reviewer Claude, 2026-10-04

Reviewer's read: Not started

The spec's best idea is that the critic never votes: a finding counts only once a test reproduces it. Elsewhere in her system the same idea is already live (a gate that refuses builds whose acceptance was green before the change), and it caught real vacuous work on its first night. In the harness, with the official grader downstream, a critic has to beat the vote on the cells the vote gets wrong, and on dev there are five.

How it is measured proposed

Arm h7 against h1-v41 on the harder set; a planted-defect fault test first.

Adoption rules shared by every arm: How the tests work.
