FA-86785 / Procedural level generation constraints / Member archive

Encounter pacing along the critical path: Encounters one tile too far apart · case 05

Levels contain fewer encounters than designed.

Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Proposed positions are deduplicated and taken ascending. A position is legal when 1 <= pos <= length-2, is not a rest checkpoint (pos % rest_every == 0 when rest_every > 0), and lies at least min_gap after the anchor: the later of the last accepted encounter (initially the start, 0) and the last checkpoint at or before pos. Returns accepted positions.

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.

One recorded failure

This sample comes from the broken implementation of a controlled reproducer.
