## Decisions ## Decisions
- **Distant drill aim is normal (t41, 2026-10-26).** The owner normally points beyond the
drill's reach and expects players to do the same. Keep the pulse colour and light crosshair,
mark the pulse's far edge, and omit distance warnings for the drill. Other tools still warn.
- **Silo contents are visible without opening the gate (t38, 2026-10-26).** The owner wants
contents beside the cursor anywhere over the outline and a material-coloured fill window at
every zoom in both looks, while keeping the real steel silo shape.
- **Square corners hold grains (t39, 2026-10-26).** The owner wants square wall staircases to
hold material instead of leaking through each touching corner. Powder, liquid and gas cannot
step diagonally between two solid neighbours; powder neighbours still allow free piles to
slide as before. Free flyers and diagonal screw intakes obey the same solid-corner boundary.
Screw lane transport is unchanged. World generation disables cell corner sealing while
settling loose ground, preserving existing seed layouts. This supersedes the square-wall
leakage described in the t36 decision below.

- **Sloped belts and filters (t40, 2026-10-25).** The owner asked for belts, then filters, to work
diagonally like tubes and walls. A Belt or Filter drag at about 45° lays slope-shaped blocks
whose face is a running belt, carrying grains and bars up or down in the drag's direction at
flat-belt speed; the face grips its load, so nothing slides back. A sloped filter drops what it
passes out underneath and carries the rest. New block codes (19-22), so saves still load.

- **No backward compatibility for now (2026-10-26).** The owner will start a new world after
changes: no one is playing the game for real yet. Changes may break old saves and blueprints;
don't add migration or alias code for them (first used by the t44 rename to screw conveyors).
- **No uphill sloped filters (t43, 2026-10-26).** The owner wants sloped belts and filters to be
realistic in how they look and behave. Real sorting screens run flat or tilted downhill and
shake; none climbs a 45° slope. So filters are flat or downhill
only; to sort while lifting, run a sloped belt up, then a filter. Not built yet.
