Finishes the lane A round-2 list that f0982e7 (the rescued first half) left open:
- Biome-tint re-eyeball under the colorspace law (#4 second half). Verdict: all
six ART_BIBLE tints stand, biomes.js untouched — the wash was wall_material's
round-1 constants, tuned on the raw framebuffer. Retuned: rim pow 2.2->3.0,
rim gain 0.9->0.35, textured curve (0.35+d*.95)*.9 -> 0.12+d*0.60, procedural
d*.8 -> d^2*.65, sheen .10->.04, matcap .22->.14. Rationale documented
in-shader. Verified on a new six-biome contact sheet (?lvl=biomes, SIX_BIOMES
fixture — kept as permanent kit), the real L2 hiatus, and an arena interior.
Evidence: round2_tint_*.png x6 + two *_retuned frames. qa GREEN.
- Stomach-arena shape read for C (#7): recommend the spline-swept room (arena =
"open" mode over an s-span; fundus dome stays a welded icosphere; chained
spheres rejected — crease rings + union collision for a worse look). Full
argument NOTES §-> Lane C + round2_stomach_arena_sketch.svg. Triplanar
deliberately deferred: the swept room obsoletes it where it mattered.
- Ruling #5: harness -> web/dev/laneA_world.html (+DBG.post to the house shot
sink); _fixture.js stays — the spline selfcheck asserts against it, now
documented in-file. launch.json: guts-a on 8145.
- NOTES + progress written for both halves; ROUND2 mid-round box updated: lane
A's round-2 list is closed, only round-3 items remain.

Textures (6 walls + normals + wet matcap, $0, ~64s on the m3ultra MPS):
- FLUX ignores "seamless tiling" (seam_error 3.7-17.9); a 4-way cosine
partition-of-unity blend of the four half-rolls fixes it exactly -> 0.87-1.32
- levels-normalised the pack to one exposure (means were 0.18-0.32); these are
detail maps multiplied into a biome tint, so per-prompt exposure read as a
broken tint rather than as dark tissue
- prompt-kit experiment rejected + recorded: PROCITY's "uniform coverage" clause
in the STEM cured centred subjects but flattened the pack; framing words now
live only in the two subject prompts that needed them
Audio (1 bed + 4 sfx, 4.2s render, 0.61/10MB, ogg+m4a dual-ship):
- bed-esophagus 24.000s, loop seam 0.32 (wrap step 3x smaller than inner step)
- cascaded lowpass poles: one-pole at 900Hz left 16kHz only ~25dB down = hiss
- rewrote the spectrogram sheet (per-clip peak, log freq) — the first one was a
saturated rectangle, and evidence you can't read is not evidence
assets.js: miss ledger + misses() — Lane A found that a drifted slug falls back
procedurally forever with no error. Each distinct miss now announces itself.
Also: shot_sink.py (canvas -> docs/shots/laneD, correctly named) and a dev
texture viewer that imports the stub world read-only for the eyeball law.
