feat(simulation): climate-derived fields + frozen 17-zone morphology (T-1025, T-1027)
T-1025 (D-239 §2) — climate-derived fields, all from the temperature(+moisture)
primitive:
- precipitation_class + glaciation_grade re-keyed to (temperature_c, moisture_q)
inputs (were keyed off raw body params); river_threshold signature follows.
- New VegetationClass (Absent/Barren/Scrub/Forest/RiparianScrub/RiparianThicket)
+ derive_vegetation: treeline bands x elevation, structural Forest->Scrub->Barren
no-skip, riparian 1-3 tile band; airless (temp None) -> Absent.
- 21 tests.
T-1027 (D-239 §5/§6/§7) — morphology classifier:
- FROZEN 17-zone MorphologyZone enum exactly per D-239 §6 (OpenOcean..Wetland,
repr(u8) pinned). Removed legacy Sea/CoastalLowland/Island/Canyon/Unknown;
all consumers (skeleton_gen street_topology) remapped to nearest D-239 zone.
- 8-family gated decision tree (LavaField..AlluvialPlain fallback) over integer
inputs; hard gates: Fjord>=GlaciationGrade2, LavaField=Volcanic tectonic,
lithology slope/form laws (§8). 4 sub-classification zones (TidalFlat,
Estuarine, Alpine, Wetland) derived from family + elevation/water.
- Build-time compatibility-matrix invariant tests (§7): MeanderReach<->Volcanic
and Volcanic<->Fjord forbidden adjacencies structurally prevented by gate order.
- 13 tests incl 17-variant completeness + discriminant pinning.
D-010 integer discipline throughout. cargo test 1534 pass, clippy -D warnings
clean, fmt clean.
