Answers Jahni's standing wish directly: "in the best of both worlds, i'd
like the system to not rely at all on the handmade ones."
Three arms, same size, same measurement, same criteria:
approach survival walkable mean feature-scale mean
corpus blend (today) 13/16 81% 0.0661 92.3
naive uniform 7/16 44% 0.0126 64.6
constraint-sampled 7/16 44% 0.0129 31.4
⭐ THE ANSWER IS NOT THE SURVIVAL RATE, IT IS THE QUALITY GAP. Constraint
sampling produces VALID worlds -- it passes the primordial law more often
than naive rolling (1 law failure vs 3) -- but the survivors are materially
worse: ~5x lower walkable fraction and ~3x lower feature scale. A composer
that emits technically-passing but uniformly mediocre places has not solved
the problem.
So the corpus carries something the declared constraints do not. §3.3 said
independent rolling destroys the CORRELATIONS; stating those correlations
explicitly recovers validity but not the tacit quality that authored
vectors encode. That is worth knowing and it was not knowable by argument.
⇒ VERDICT: keep the corpus in production. Constraint sampling is a
corpus-free BOOTSTRAP (it can seed a corpus from nothing), and PROMOTION
(Tier 5) is the real route off handmade content -- dilution, not removal.
Naive rolling is rejected outright.
⚠️ UNDER-POWERED, stated plainly: 16 candidates per arm, not the 256 the
spec asked for -- the fixed 8M-cell box/law workload made 256x3 too slow to
finish. The 5x walkable gap is large enough to be believable at n=16, but
the survival rates (44% vs 44%) are not separable at that sample size. Do
not quote these as precise.
Authored-corpus audit, and Codex read it correctly: 3 of 12 vectors violate
the proposed relations (DA_Strate3 room coverage 2.68 vs bound 0.35;
Default_SurfaceWorld ground bound; Default_VerticalShafts shaft radius 5 vs
roughness margin 5.875). That does NOT mean those assets are broken -- it
means the new relations are conservative HYPOTHESES, not universal corpus
invariants. Recorded as such.
Box law held across all three arms: 768 proved, 673,486 voxels brute-forced,
0 violations. §6.2 did not reopen under corpus-free parameters.
Also noted: "uniform within clamps" was underspecified in my spec -- many
fields have no finite upper clamp. Both corpus-free arms use the same
declared H-relative envelopes so the comparison stays honest.
Build clean, CorpusFree green, WorldRadiusVoxels=0.
