Historical: Delayed-cue recall

The :delayed_cue task tests whether controller state retains a binary cue through a blank interval. Only response-period actions contribute to the decision. Persistent and hidden cue modes support controls with identical seeded worlds.

The software is integrated into the four-task v2 benchmark. Its initial model results are development observations near chance; confirmation remains pending. Read the task guide for a runnable example, outcome definition, controls, and interpretation limits.
