A slope's seal can sit in a cell its neighbour leaves open (a slope's
open corner, or under a grate, screw or screen), but removal only
cleared it when the neighbour was a sloped wall, so cutting a sloped
belt next to a sloped filter or grate could leave a one-cell belt that
nothing owned and nothing could remove. Removal now asks whether the
neighbour fills that cell itself, and loading a world clears belt and
screen cells that no block or seal owns.

A piece added to a running sloped belt kept its own cleat phase, so at
the seam a rib could start just behind another and push its pocket into
it, stalling the whole run with only a few grains. Every block of a run
now takes the phase of the run's lower-left block.
Downhill sloped belts no longer have cleats: they carry like a flat belt
(90 grains/s, was 38) and draw only the sidewall.
Middle click on a sloped belt's band, where it is drawn into the empty
block beside it, now picks the belt.

Nothing carries the load on a slope but the ribs: each belt step every
rib moves one face cell and pushes the grains in its way, the layer on
the belt is only dragged by friction that gravity beats on 45 degrees,
and heaped grains roll back. Ribs never pass through grains or into
machines; a run that can't push stalls. The foot of an uphill run
scoops the feed into pockets. Ribs drawn as rubber bars in both looks.

The magic grip is gone: cleats every 8 face cells, 6 grains tall, carry
pockets uphill (about 71 grains/s against 90 flat) and overflow rolls
back. Sloped filters always run downhill; grains travel by gravity and
a shake, and sorting stays exact. Drawing needs another pass.

Player text says Screw conveyor; code uses screw (BP_SCREW, piece id
screw, screwIntake...). No compatibility code for old saves or
blueprints. Suite outputs match before and after apart from names.
