The voxel tier read flat (the D-245 "0–3 m, no hills to navigate by" bug): family generators set elevation from elev_q at a compressed scale plus only ±4 m micro-scatter, and detail-scatter's mid-scale relief (D-243 §2) only ever reached the district tier (elev_q), never per-voxel elevation_m. - detail_scatter.rs: extract the enveloped-fBm core; add `voxel_relief` at the 0.25–2 km octave band (vs the district 4–40 km band). - voxel.rs: add the mid-scale relief post-dispatch in derive_voxel_column, body-global SeedDomain::VoxelRelief seed (position-keyed), f64 truncated to integer metres (D-010). Envelope = slope_q*3 + elev_q — the coarse heightmap gives slope_q ≈ 0 even on high ground (Arbour max 13), so elevation must drive ruggedness. Flat families only (Alluvial/Lava/BraidedDelta/Dune/Meander); the dramatic families already carry strong internal relief and WaterBody stays at sea level. - seed.rs: SeedDomain::VoxelRelief (D-224 domain separation). - believability.rs: new `contrast.voxel_relief_m` metric — mean within-district elevation range over a 2 km transect (a single 64 m sample chunk is narrower than the relief band) + a "voxel relief" criterion. Arbour @ yolo: voxel relief 5 m → 59 m, 6/8 → 7/8 criteria (remaining fail = the Q-123 vegetation-denominator item). Edict 59 m. Golden regenerated; 1586 lib tests + believability harness (determinism) pass; clippy -D warnings clean. D-239 amended (T-1081); Q-123 item 4 updated. Deferred to Q-123/follow-up: the provisional span + threshold, and a per-body hypsometric absolute-elevation model. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
