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.
