Stryker over Zone.cs (231 mutants, scoped by --mutate to this cut's file)
found two real gaps, both NoCoverage/Survived, not equivalents:
- Zone.EvaluateBelt and AsteroidBelt.Evaluate -- the renderer's own path
(ZoneRenderer.cs Update, AsteroidBeltUI.Update) -- were never called by any
test, so the whole batch body and its loop bound were unreached.
EvaluateBeltFillsEveryAsteroidExactlyAsChunkPoseWould pins that the batch
path fills every index exactly as the per-index ChunkPose would, closing
the gap without duplicating the orbit formula a second time.
- AsteroidBelt.Radius (data.Asteroids.Max(a => a.Distance)) had no assertion;
a Max-to-Min mutant survived. BeltRadiusIsTheFarthestAsteroidsDistance pins
it, since the renderer's visibility bounds and minimap mesh both size off
this field.
Full suite: 262/262 green (260 + these 2).
