Tier 4a. The first piece of the composer that INVENTS rather than fixes.
The design, from COMPOSER-NOTES §3.3: do NOT roll 73 parameters
independently. The coherent region of a 73-dimensional space is a
vanishingly thin sheet and uniform sampling never lands on it -- and
independent rolling destroys the CORRELATIONS (room spacing <-> room
radius <-> tunnel length) that make a vector coherent. So blend known-good
vectors through the existing FStrateGenerationParams::Lerp instead:
constraint satisfaction is free, because a convex combination preserves
every relation holding in both parents. Min <= Max stays true because it
was never broken.
Built: FVoxelStrateCorpus (loads authored vectors, computes per-field
spread), VF_RollStrateParams (2-3 weighted parents, convex blend, jitter
by +-15% of each field's MEASURED corpus range -- not by the clamps, which
are "don't type nonsense" limits, not "this makes a good world" limits),
and VoxelForge.Composer.ParameterRoll. Determinism asserted by rolling
twice and comparing every field.
Exclusion list found by reflection, not assumption: StrateTopWorldZ and
StrateBottomWorldZ (manager-owned runtime bounds) plus 34 terrain-op
transport fields (TerraceStepHeight..PinchLength) that are copied in from
room operators rather than being strate tunables. Bools inherit from the
dominant parent; ints/enums use Lerp's existing snap.
⚠️ THE RESULT IS VACUOUS AND SAYS SO. 64/64 candidates "survived" -- but
the corpus loaded ONE vector (DA_Strate3), so all 64 are bit-identical.
100% survival of a single point is not evidence of anything. The box-
verdict check is vacuous too: 2,560 boxes, 0 proved, 0 voxels brute-forced,
so §6.2 is NOT closed. The test emits a warning saying exactly this rather
than reporting a clean pass, and no workaround was added to hide it.
Four strate assets exist (DA_Strate1..4); the loader found one. Fixing the
corpus is the next task -- with one parent there is nothing to blend, and
every number above is a placeholder.
Also owed: clamp metadata is editor-only, so the safety net needs a
cook-time baked table before this ships.
Nothing calls the composer from any runtime path (§3.1: offline, once per
season, on a build box).
Build clean, 23 tests / 0 failed (1 carries the deliberate vacuity
warning), verified in VoxelM.log.
