# Eight looks per episode against one basket, so a rollout here costs roughly eight times a
# one-shot `grand-exchange` rollout in requests and rather more than that in tokens: the
# whole conversation is replayed to the model on every segment. `num_tasks` is half the
# one-shot config's for that reason, not because fewer baskets measure better — realised
# P&L over sixty ticks is the noisiest number in this repository and the ladder is read
# over five blocks of twenty-four.

# The graded window is not configurable: 8 looks x 7 ticks + a 4-tick tail = 60, and every
# constant in the reward was measured against that shape (`measure_ladder.py --sweep-shape`).
