Overview

I gave GPT-5.6 Sol one bounded refactor inside Decksmith, a private production system that researches, scripts, narrates, renders, and prepares videos.

The first pass reached 109 focused tests with one skip. A separate review then found the missing guarantee: the report could match the selected story while no longer identifying the current video bytes. A targeted correction bound the validated artifact to its project-relative path and SHA-256 digest.

After canonical code generation, the affected suite passed 140 tests with one skip. Ruff, editor typecheck, and the diff check passed, as did 50 selected drift guards with one skip. That is a conditional verdict about one isolated refactor and its review loop—not a claim that the entire repository is green or a universal benchmark of coding performance.
