docs(governance): file D-239 tile derivation contract, resolve Q-101
Resolves Q-101 — how a coarse Layer-1 cell + seed becomes coherent ~1m
voxel geometry across the scale jumps. The tile-derivation-contract
workshop output:
- three-carrier refinement chain RegionProfile -> ChunkContext -> VoxelColumn,
pure deterministic, no authoring at the derivation layers
- district-temperature climate primitive (2x2 km, C, nullable) + separate
moisture; everything climatic derives from temperature(+moisture)
- scattered, transient freeze/snow model (freshwater +5..-10, sea ice own
band, snow moisture-gated; forms cold phase / melts warm phase)
- stateless f64-to-voxel domain warp (anti-squaring)
- 8 morphology families over a frozen 17-zone vocabulary, gated decision tree
- seams prevented at source (gate ordering + build-time matrix); valid
geomorphic seams kept sharp + warped
Includes workshop brief, round-1 positions, and workshop-outcomes.md.
