Hoshe REQUEST_CHANGES + Tyre APPROVE:
- Riparian vegetation logic was doubly-wrong: it granted the micro-oasis only
in the impossible cold case (temp < -50, no liquid water) and DENIED it in the
intended hyper-arid case. Split: extreme cold -> Barren always; hyper-arid ->
RiparianScrub iff near perennial water. (Hoshe #2)
- morphology_zone_has_exactly_17_variants was misleading (asserted >=16). Rename
to morphology_zone_region_scale_emits_16_of_17, tighten to ==16, and document
that BraidedPlain is the lone region-unreachable zone (needs lithology, deferred
to ChunkContext) and that Lake IS reachable. Tyre's 'Lake also deferred' was a
false positive (ocean 60-79 -> Lake). (Hoshe #1, Tyre #1)
- derive_morphology_zone docstring now lists the real multi-path emission sites
for TidalFlat/Wetland, ValleyFloor/RiverBank as their own gates, and BraidedPlain's
deferral — the §6 parent-family names are descriptive, not exhaustive. (Hoshe #3, Tyre #2/#3/#4)
- D-239 record: added a T-1025/T-1027 implementation note (enum freeze location,
16/17 region reachability + BraidedPlain deferral, §7 gate-ordering interpretation).
No vocabulary change. cargo test passes, clippy -D warnings clean, fmt clean.
