Parent State ID: 1
State Depth: 2
Action Taken: stack(b, c)
Action Reasoning: Since Block B is currently held by the hand, the next best action is to stack Block B on Block C, which directly aligns with the goal state.
State Description: Block C is on the table and clear. Block B is stacked on Block C and is no longer held by the hand. Block A is on the table and clear. Block D is on the table and clear. The hand is empty.
Action Path: ['unstack(b, c)', 'stack(b, c)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Block C is incorrectly described as clear in the new state text description.
