FA-10677 / Raster clipping / Member archive
Span merge touching · case 02
Touching coverage spans remain separate and create redundant raster work.
Case contract
Return sorted disjoint half-open raster spans after dropping zero/negative lengths and coalescing both overlapping and adjacent spans.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| fixture 1 | [[0, 2], [2, 4]] | [[0, 4]] | Failed |
