# fac-insert

Transfer items from your inventory into an entity via the game bridge.

## Behavior

- The target entity must exist at (x, y) and accept the item (furnaces
  take fuel + smeltable ore; chests take anything).
- Returns the target's state after the insert (contents included).
- Failure carries the standard deviation report.
