Watch: Use appearance counts and an outcome-dependent replacement rule to identify the uniquely forced participant or outcome at a target step. The shell keeps the complete question visible, reserves the canonical reply band, and reveals proof on the same task objects.

Misread: Child action: Use appearance counts and an outcome-dependent replacement rule to identify the uniquely forced participant or outcome at a target step.

Selection

Fresh independent work can move toward Core, Transfer, or Challenge routes; help use or confusion keeps support visible.

Help

Hints keep attention on the visible structure; reveals show the path without counting as independent evidence.

Presentation

Presentation can reduce reading and interaction load without changing the selected skill. Practice focus can bias compatible work without breaking prerequisites or story fit.

Story fit

  • story beats with visible logic state, manipulable evidence, and a bounded player action
  • Episodes whose mathematical action is filter legal hidden-state histories in public event order until one target identity or value is forced.
