Generated on MODELBEAST flux_local, on-device, $0.00. Lane D's pipeline used
unchanged; **D owns these — ratify, retune or bin them.**
Why A did D's job: the six-biome tint contact sheet could only judge 3 of 6
biomes for real (oral/large_intestine/appendix had no pack and fell back to
procedural), and you cannot ratify a tint against a stand-in. All six are now
textured — the set ART_BIBLE §Biome palettes promises.
- wall_oral_a/b, wall_colon_a/b + normals. Seams 6.35/9.30/14.06/6.37 -> 1.01/
1.08/0.74/1.36 (D's "indistinguishable" band; the shipped pack's weakest is
2.39). Means normalised to ~0.50 by D's derive_maps, untouched.
- appendix wears the colon pack at its own gold tint (TEXTURE_SHARE in
world/index.js) — anatomically it IS colon tissue, and it's ART_BIBLE's
"one texture, two biomes" law for zero bytes. Distinct from the temporary
slug map; keep it when that dies.
- oral_a took three subjects. v1 named an ORGAN ("tongue") and FLUX drew the
organ's silhouette — D's "one urchin of villi" in a field's clothing. v2 named
the tissue but papillae are 3D projections, so perspective gave it a vanishing
point that tiles into starbursts. v3 asks for squamous cell pavement: flat by
construction. Rule for the kit: prompt the SURFACE, not the FEATURE.

PROVENANCE DEFECT FOUND AND FIXED (-> Lane D):
batch_textures.json recorded, for 4 of 6 walls, the prompt from the framing
experiment D tried and rejected — not the prompt that made the shipped pack.
record() only runs on generation, so reverting a prompt while keeping its image
(exactly what D correctly did: "four winners kept untouched rather than churned")
drifts the record silently. Proved by regenerating esophagus_a at seed 1101 under
both prompts: the code's prompt reproduces the shipped wall, the recorded one
gives the bland wood-grain D described rejecting. Evidence:
docs/shots/laneA/round2_provenance_probe.png. Records re-pointed at the code's
prompt (images untouched — they were never wrong).
New: gen_textures.py --verify-provenance + qa.sh gate 5b, so it cannot rot again.
qa GREEN incl. the new gate; 11/11 provenance verified; all six biomes eyeballed
in engine (docs/shots/laneA/round2_tint_*.png).

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.

Landed before the cut: crestSpeed(s) + CREST_FACTOR 1.6 (ruling #1) with selfcheck
asserts; radius blend widened +/-12 -> +/-25 (C's #4 dependency) + no-cliff selfcheck;
per-segment wave.amp override as per-vertex aWaveA (ruling #8); colorspace law in the
wall shader (ruling #2); TBN normal maps + matcap + dual detail layers (D's perturb(),
trap documented in-shader); sample(s, out) v1.2; slug map shrunk to the two real
mismatches. Evidence: docs/shots/laneA/round2_L2_*.png.
Cut off before: NOTES/progress, stomach-arena shape read for C (task #7).
Committed by F to protect the shared tree; spline + qa selfchecks GREEN at commit time.

Implements THE WORLD CONTRACT (TECH.md) in web/js/world/; drop-in for the stub.
boot.js now runs this on C's L2_esophagus (3600u, hash cefc4f83), zero console errors.
- spline.js: centreline + arclength LUTs + parallel-transport frames + radius law +
peristalsis phase + project() + hash(). No three.js import, so qa can run its
14-assertion selfcheck headless.
- curviness is solved from a curvature budget, not authored as an amplitude: the pinch
guard caught the tube folding through itself on a wide+curvy join (turn radius 9.9 vs
tube radius 17.2). C can no longer author a pinch.
- peristalsis: global OMEGA, k(s) = OMEGA/flow(s), phase K(s) = integral k ds. A crest
therefore travels at exactly the local flow speed, so "surf the crest" == "ride the
current". Esophagus wave amp 0.9 -> 1.4 (measured): moves wallRho for Lane B.
- tube.js: chunked streaming, seams aligned to biome joins, arenas own their s-span.
- arena.js: displaced icosphere shells v0 (three's polyhedron detail is 20*(detail+1)^2,
not 20*4^detail — 720 tris was far too coarse); fog sized to the room, since biome fog
tuned for 100u corridors renders C's 360u acid sea as a black rectangle.
- index.js: prefers assets.texture() over get() (get returns raw JSON a shader can't eat),
plus an explicit slug map — D's wall_smallint_a vs biome id small_intestine would miss
silently forever under the assets-optional law.
Measured (C's real L2 + D's real pack, 1920x1080, renderer.info): 8 draws worst frame
(budget 150), 74k tris (500k), no geometry leak across a full sweep, <120ms load,
pinch ratio 3.32. fps not claimed — the screenshot pane runs tabs hidden, pausing rAF.
