The shape read in LANE_A_NOTES was written from reading code, so I built it to
find out if it was true. Flyable: web/dev/laneA_world.html?dbg=1&assets=1&lvl=swept
Nothing here is imposed on anyone: every addition is additive and a level that
opts out behaves exactly as today. C can bin the whole proposal and lose nothing.
WHAT THE PROTOTYPE DISPROVED (my own cost estimates, all four):
- "radial resolution must scale with radius" — wrong. 64 segments is a 0.05u
circle error at r=70. The arena needs it because it fbm-displaces; the tube's
wave is smooth in theta. No change made.
- "cap geometry at the span ends" — a thinko. The canal is continuous; a room is
a fat part of it. Only the fundus dome caps, and it stays an icosphere.
- cost — cheaper than feared: 9 draws / 98k tris worst-frame for a radius-70
cathedral vs 8 / 74k for the L2 corridor. No leak over a full sweep.
- "one schema flag" — held. `segments[].mode: "open"` is the entire ask.
THE TWO REAL COSTS, NEITHER PREDICTED:
1. D's `tile[0]` is a COUNT, not a density — only a texel size if radius never
changes. Measured 6.1:1 smear at r=70. The wall now derives the count from
each ring's own arc length (aRadius attr + uThetaSpan); D's authored numbers
keep their exact meaning at their reference radius, no re-authoring. That fix
then laid a seam down the canal (a fractional count can't wrap) -> rounded to
an integer, seam gone. Not a no-op on corridors: L2's hiatus takes 3 repeats
where it took 4, which is the texel size correctly holding still as the pipe
narrows. Eyeballed.
2. MY OWN PINCH GUARD WAS WRONG and would have blocked C. The fixture scored
1.30 and "failed" the >1.5 law; it was never bent. stats() divided the
tightest turn ANYWHERE by the widest radius ANYWHERE — 996 units apart, a
bend in the radius-13 pylorus against the radius of the sea. Locally its
worst point is 6.4. pinchRatio is now min over s of turnRadius(s)/radius(s).
Provably one-directional (global <= local by construction) so nothing that
passed can fail; real levels GAINED headroom: L2 3.32->4.16, L3 1.91->6.99,
L1 2.11->6.06. This mattered — the guard is what backs the round-1 promise
that C never has to think about curvature.
THE ACID SEA (world/acid.js, `level.acid {from,to,height,biome}`):
Flat emissive #c8ff3a, level and NOT tube-following — that's the mechanic. The
best find of the session: `height` is ONE NUMBER that tunes the level. Measured:
-18 -> 0% of the sea floor is dry shallow, -55 -> 14%, -62 -> 48%. So C's "position
IS the resource" falls out of the radius wobble they already author — the mucus
shallows are just "where the wall rises above the waterline", nothing to place —
and rising acid literally drowns them: free escalation, same scalar their event
pump drives. Also disproved my own claim: the centreline stays level (+/-1u over
700u), so shallows come from radius wobble, NOT the canal's bends. C must author
vertical bends deliberately if they want depth by anatomy.
Stated plainly, not papered over: the waterline is prototype quality (the plane
meets faceted rings and the shoreline steps). Acid does not drain the coat —
depthAt(pos) is the hook and the cost is Lane B's call. Nothing drives height but
DBG until C's events do.
qa GREEN incl. the new provenance gate; spline selfcheck green; L2 corridor
re-eyeballed for regression. Rulings requested from F in NOTES §-> Lane F.

GUTS — a fantastic voyage through the alimentary canal
Browser flight-combat game (three.js, zero build step). You pilot ENDO-1, a microscopic probe, mouth → rectum through five anatomically-grounded biomes: ride peristalsis down the esophagus, cross the acid sea of the stomach, thread the villi forest of the small intestine, survive the gas swamps of the colon. Fantastic Voyage × Star Fox × Descent.

Run it
cd web && python3 -m http.server 8140
# http://localhost:8140 — the game
# http://localhost:8140/?stub=1&dbg=1 — stub world + debug HUD (works from day 0)
No bundler, no npm, no build. ES modules + import map; three.js r175 vendored in web/vendor/
(never CDN — the game must run offline). Before you finish a session: bash tools/qa.sh.
The one-paragraph tech pitch
The whole canal is a spline. World position is (s, θ, ρ) — distance along the canal,
angle and radius in the cross-section. Tube walls are chunked extrusions along
parallel-transport frames; peristalsis and breathing are vertex-shader displacement
(cheap, squishy, everywhere); collision is an analytic radius test (no physics engine).
Caverns (mouth, stomach) switch the same controller to free 6DOF. Look is synthetic
scanner — dark endoscope void, SEM-style monochrome walls with FLUX-generated detail
textures, emissive-coded enemies. Everything is seeded + deterministic, and every asset is
optional at runtime — the game boots and plays asset-free with procedural fallbacks.
Hard laws (all lanes)
- Determinism. No
Math.randomoutsidejs/core/rng.js. Seeded RNG only. qa.sh greps. - Assets are optional. Missing texture/model/audio ⇒ procedural fallback, never a crash.
- Eyeball everything. Visual work isn't done until a screenshot is in
docs/shots/laneX/. - Perf budget: ≤300 draw calls, 60 fps on M-series / mid laptop. Measure via
window.DBG. - Free-first. Local MODELBEAST generation before any paid API; fal.ai is a gated fallback (John's go). See PIPELINE.md.
- Git: stage only your exact paths, commit + push each session, never
git add ..
Deploy
Target: partly.party (static). Not wired yet — when it's time, consult the deploy-map skill
and run ship-check first. Origin: ssh://git@100.71.119.27:222/monster/guts.git.
