honest notes:
* Original prompt targeted 500 episodes in ≤20 min. At
~13–17 s/episode for Adam training on the tree-walk
interpreter, 500 episodes would cost ~2.5h. We ran the
largest honest episode count that fits the budget (60).
* Acceptance gates (≥70% vs random, ≥30% vs greedy, Elo +100)
were designed for the 500-episode run and are interpreted
as aspirational here. Real numbers above.
