jpmschweitzerandClaude Fable 5 5cb63b6867 feat(simulation): T-1162 — invention octaves into the Atlas window path (coast crinkle, quarter relief, vegetation patchiness)
Coast: WARP_OCTAVE_WAVELENGTHS_M 5->9 entries (262144m down to 1024m,
Quarter's Nyquist floor) with new min_wavelength_m cutoff plumbing in
coast_warp_px/warp_fbm (the warp previously had no cutoff at all).
Relief: invent_primitives feeds the VOXEL band (1024-128m, salted) into
elev_q/slope_q under the same envelope/cutoff discipline. Vegetation:
new vegetation_invention module — two-tier (BodyParams+latitude envelope
ceiling; single blended fBm field, never-gated 100-400km massif tier at
70% + cutoff-gated district/voxel texture at 30%) perturbing moisture_q
OUTPUT so precipitation/glaciation/vegetation shift as one world-fact;
wire format unchanged. MIN_WL_BANDS_M 5->6 (adds 1024m band).

Mid-implementation correction caught by tests: District's quantized
floor is 4096m (OCTAVE_WAVELENGTHS_M[3]), not 2x DISTRICT_M — the 8192m
and 4096m coast octaves are legitimately District-admitted enrichment;
only 2048/1024m coast + the voxel band are Quarter-exclusive. Docs and
golden cutoffs corrected to match.

New golden: tests/window_derivation_golden.rs + fixture (derivation_
harness pattern, UPDATE_GOLDEN=1 regen) with structural guards pinning
Quarter/District divergence. Bench (zoom_ladder_bench, release): no
regression — all rungs at or below baseline (District c0 3.54->~3.0
us/cell, Quarter 2.10->1.77, orbital 1.48->1.42, n=6400 window
0.86->0.59 ms). Revert-verified voxel_relief cutoff exclusion. Server
lib 1840 passed; new module 11 tests; district_profile 84 (+6, 1
noise-fragile pre-existing test properly fixed via 8-district
latitude-band averaging).
