Frames extracted from videos were cached by run name, in one folder per model. Runs in different manifests share names, so analysing a second manifest silently reused the first one's frames: the first analysis of the blend-statistics fix on H3 compared the old renders' frames for most runs. Latent measurements were unaffected. Each manifest now gets its own frame folder. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
