| name | fac-place |
| description | Place one entity from your Factorio inventory at a position (stone-furnace, iron-chest, burner-inserter, transport-belt, ...). You must be within ~10 tiles; the item must be in your inventory. For belt/pipe/pole RUNS use fac-connect instead. |

fac-place
Place a single entity via the game bridge.
Behavior
- Consumes one
prototype from your inventory (fac-inventory to check).
- Enforces character reach (~10 tiles): walk close first (fac-walk).
- Failure carries a deviation report:
world_changed (something
appeared there since you observed — coordinate, maybe say something),
stale_model (you never observed there recently — fac-observe and
retry), infeasible (collision/invalid with current knowledge).
- Inserters: direction is where the inserter FACES; they pick up from
the tile behind and drop to the tile in front.
- Catching a machine's output: drills and inserters eject at their
outputs to (x, y) tile shown by fac-observe — place the receiving
belt/chest EXACTLY there. Entities are wider than one tile (a
burner-mining-drill is 2x2); tiles adjacent to its center are usually
inside it and will fail with "blocked by: ".
- Placement grid: 1x1 entities (belt, inserter) sit at coordinates
ending in .5; 2x2 entities (drill, stone-furnace, chest is 1x1) at
whole numbers. Pass observed coordinates through EXACTLY — never
round. An off-grid position is rejected with the valid candidates.
