derive_chunk_context now derives channel_anchor_m and coast_anchor_m from the Region-or-higher seed path (D-239 §10); all five voxel placement sites measure distance to these anchors in continuous world coordinates: - T-1040: compute_channel_state / compute_meander_reach_channel / in_levee_band subtract the region anchor instead of measuring from the world origin axis — active channels now exist in their chunks anywhere on the body, continuous across chunk boundaries. has_active_channel is honest in both directions (band-crossing gate; floor covers the BraidedDelta belt at short wavelengths). - T-1041: fjord/cliff/gorge/delta drop their rem_euclid(64) chunk-frame folds — one valley/coastline/fan per region instead of one per chunk. D-239 §9 chokepoint widths preserved; two i32 wall-rise overflows on region-scale distances fixed by clamping before multiply. Harness: 6 new believability tests (channel presence + gate honesty at chunk (1000,-750), cross-boundary continuity, one-landform-per-region, braid-belt confinement); drainage sweeps strengthened with anchor-band chunks. Voxel golden regenerated deliberately: case A now pins a genuinely in-channel Shallow voxel on the anchor, case C a Deep trough voxel matching its label; case B byte-identical and L0/L1 cascade golden untouched (no upstream leak). Review: approved, three minors addressed (truncation-convention docs, delta gate floor, case C relocation). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
