Parent State ID: 12
State Depth: 7
Action Taken: put-down(c)
Action Reasoning: Block c is currently on top of block b but needs to be on the table for the goal state. We should put it down.
State Description: Block `a` is on block `d` and clear. Block `b` is on the table and clear. Block `c` is on the table and clear. Block `d` is on the table and supporting block `a`. The hand is empty.
Action Path: ['unstack(d a)', 'put-down(d)', 'pick-up(a)', 'stack(a d)', 'unstack(c b)', 'stack(c b)', 'put-down(c)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: The hand is not holding block c, violating the precondition for put-down.
