Two continuation assignments retained unrelated prior-task conversation context; the methodology record identifies them. Individual validation reports record browser checks and limitations.
Editorial verdict
Where this model fits
GPT-6 Luna has ten published Superbash visual runs. Eight used fresh agents; two continued unrelated prior tasks because fresh subagent slots were unavailable. Each assignment received only its canonical prompt as creative input, and the methodology records the context difference. B tier is an editorial placement for bounded work with review, not a numeric score.
