## Experiment provenance

**Experiment line:** stack line (colour-cube world). Three cubes differing ONLY in hue; day cycles relabel grasp → pick up → stack. Run pages: https://storage.googleapis.com/rbhowmik-dreamer/site/stack/index.html

The full-scene, prompt-necessary corpus that solved hue binding (go over the <colour> cube 10/10): every scene holds all three cubes, so the colour word is the only thing that disambiguates.

**What changed:** vs `stack_v2`: episodes 2101 → 2100, frames 63143 → 62659. Same task vocabulary — the new episodes change coverage, not words.

Collected in simulation (robosuite/MuJoCo, Panda): scene + wrist video, proprio, OSC actions, and a language task string minted by the project's verbalizer (certificate → instruction; the relabeler may not invent words).
