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

Day-cycle corpus: the parent plus that night's appended episodes (relabelled oracle-gated chains and/or held-context prep demos). The corpus is the memory; weights retrain from scratch each night.

What changed: vs stack_v4_day1: episodes 2400 → 2550, frames 78627 → 88182. 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).
