A multi-agent harness for programming problems, written as a Memdoor workflow. Five roles (planner, two ideators, solver, manager) and a repair worker each start from a fresh context and talk only through files on disk. A shell script that runs the samples decides success, not a model. It is the method of GVS5H (Lee, 2026: five Qwen3.8-27B models match Fable 5 on LiveCodeBench Hard).
Rebuilt with the authors' exact prompts on Qwen3.8-27B, their loop scored a mean of 9.8 of 10 over five passes on the first ten LiveCodeBench Hard problems, against 9.6 for their own harness and 8.0 for Fable 5 alone (below, every run published).
The coder wrote these files itself from a description of the method (2026-10-25). Nobody hand-wrote them.
