FA-86661 / Procedural level generation constraints / Open access

Wall autotile bitmask: North bit samples the south neighbour · case 01

Wall tops render as if the wall continued below.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The north bit uses a +1 row offset (y-up assumption) on a row-0-north grid.

VERIFIED REPAIR

Restore `((1, (-1, 0)), (2, (0, 1)), (4, (1, 0)), (8, (0, -1)))` at the north offset step.

Unsuccessful approach: Swapping north and south bits mirrors every vertical wall piece.

Case contract

For each '#' cell the mask sums N=1, E=2, S=4, W=8 for 4-neighbours that are '#' (row 0 is north). Out-of-bounds neighbours count as walls when same_oob. Non-wall cells get -1. Returns rows of integers.

Why this case matters

Procedural generators silently emit unplayable or unfair levels when a single constraint check uses the wrong boundary, axis, neighborhood or update order; the defect is visible in exact generated geometry.

Verification & scope

Deterministic toy contract stipulated for this model; integer or exact arithmetic only, not a reproduction of any specific game engine. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
