Sprinkler and Scarecrow Planner

Basic Sprinkler pattern Scarecrow 248-tile range 10×12 Greenhouse

Verified placement facts

• A Basic Sprinkler waters only the four cardinal tiles: north, east, south, and west.
• A standard Scarecrow uses the game's distance < 9 tile test. That is 249 lattice points including its own tile, or exactly 248 protectable surrounding tiles.
• The Greenhouse dirt bed is 10 rows × 12 columns. The template uses four Iridium Sprinklers with Pressure Nozzles and contains no Junimo Huts; Junimo Huts are outdoor farm buildings.
• Sprinklers work in the Greenhouse on valid placement tiles. A Pressure Nozzle trade in Qi's Walnut Room gives 4 nozzles for 20 Qi Gems.

Coverage boundary: sprinkler offsets and scarecrow distance predicate match the local 1.6.15 game logic; the Greenhouse template models only the 10×12 dirt bed.
