New ladder.js. The whole mechanic is 200 mm: the fascia bracket sits at 2.48 m,
a 1.72 m person's hands reach 2.20, and E's ladder tops out at 2.90. The asset
and the yard were already built for each other; this is the verb between them.
Carry-ladder is a second carry type, so the ladder and the spare compete for the
same pair of hands and a fascia repair costs two trips while a post repair costs
one — DESIGN.md's "limited hands" rule doing real work, and the reason the house
is the expensive anchor to depend on (which E's ratingHint 0.35 / collateral
"gutter" was already saying in the data).
Climb height is code-driven with ClimbLadder playing on top — the knockdown
precedent, since _rotOnly strips the root and a clip can no more lift the body
than Falling could lay it down. You can't brace up there (both hands on the
rungs), the wind's bar drops to 0.6x, and being blown off is a fall that feeds
straight into the existing get-up chain.
needsLadder is scoped to the fascia on purpose: a height test would have roped in
the 3.95 m posts and 5.05 m limbs, made every repair a two-trip job, and silently
invalidated the recorded §7 run — and it isn't true to rigging either.
Landed with no change to main.js: createLadder self-wires from createPlayer,
which Lane A already hands the scene, world and interact.
Two bugs found by building on my own API, both now asserted: a canUse that reads
player.state cancels its own hold (starting a hold sets busy) — it ate the climb
AND the reach gate before I keyed both on physical height instead; and onLadder
had to become height-based for the same reason. Documented on register().
Selftest 194/0/0 (was 184). Full loop driven by hand in the real game.

The face's first act was to expose that garden HP barely responds to rigging: a
perfect rig scores 53% on storm_02 and rigging nothing at all scores 48%. Cause
is measured (rain shadow decays 0.38 -> 0.04 as wind builds) and it is not a bug
in anyone's lane — but it means decision 7's headline score is nearly
independent of the game. Flagged for Lane C with the numbers; the design call
about whether garden HP is even the right storm score is left open.

SPRINT4 §Lane A 1-5. Everything the game already simulated was invisible to a
stranger; you can now play a whole round with eyes and a mouse and never open the
console.
hud.js only ever READS — it takes no decisions and owns no state worth keeping,
so it can be this chatty without anything drifting. Corner load bars are
world-anchored rather than screen-anchored because a number in the corner of the
screen can't tell you WHICH shackle is about to go, and that is the entire
"...the shackle, I knew about the shackle" moment. They hold constant screen size
with distance: a house corner is 18 m away from the posts, where a world-sized
bar is a few unreadable pixels.
Prep is Lane B's createRiggingUI wired to the phase machine — their picking was
already complete, this is the hands. Forecast reads the three authored storms, so
the difficulty select came free: Sea Breeze / Southerly Buster / Wild Night with
real peak wind, gust character and change time.
Two bugs the wiring surfaced, both found by playing rather than reading:
- The rigging session survived "play again": a second round started at $35 with
three corners already hung, and the four anchors you clicked were silently
ignored because the session was full. resetRig() walks it back through the
session's own public moves, so the economy stays the one source of truth.
- The forecast card's lifetime was owned by its own button, so any other route
into prep left a card floating over a live game eating input. The phase owns it
now.
Verified by playing it: good rig on the wild night wins at 53%, the same yard's
cheap drum-tight span loses 4 corners, the gentle night with a good rig ends at
93% "not a leaf out of place". Selftest 184/0/0.

Leads with the router allowlist gap: rig.step() gets the router, which doesn't
forward rainMmPerHour, so B's ponding would pass every assert and do nothing
in-game. Two lines in main.js.

SPRINT4 §Lane C 2/3/4.
PONDING DATA (decision 10). rainAt() was a dimensionless 0..1 — fine for drop
count and opacity, useless for water mass. Lane B would have had to invent the
mm/hr scale, which is exactly the "default-off code tuned by a constant I
invented" they rightly reverted. So the scale is storm data now:
rain.peakMmPerHour (validated 0..300; a rain curve without one is a hard error,
since ponding would silently use the default instead of what the author meant),
plus wind.rainMmPerHour(t) and rainDepthMm(t0,t1). RAIN_TIME_COMPRESSION=40 is
exported from weather.core so B applies it cloth-side rather than either of us
hardcoding 40 twice: how hard it rains is mine, how much water a sail holds is
theirs.
Calibrated to B's own arithmetic, and the numbers land on it:
storm_02 80 mm/hr severe -> 50.9 mm = 3.12 kN/corner (B predicted 3.1)
storm_03 30 mm/hr moderate -> 8.3 mm = 0.51 kN/corner (teases a carabiner)
storm_01 8 mm/hr shower -> 0.9 mm = 0.06 kN/corner (harmless, as designed)
against a storm_02 wind load of 0.2-1.1 kN. A flat rig should drown in the wild
night; a hypar pools nothing and won't notice. Asserted with B's arithmetic so
the storms are provably fit for their water before their cloth lands.
DECISION 7 helper for Lane A: sky.gardenExposure(bed, t) = rainAt x (1-shadow),
the whole drain term in one call. Note it moves on its own — the rain shadow
follows the wind, so the southerly change walks the dry patch off the bed and
the drain climbs with no corner having failed.
NIGHT PASS. sky.night is now the author's call (was: inferred from a darkness
threshold), and darkening scene.background did nothing anyway — the cloud dome
covers it at 0.85 opacity, so an overcast-grey texture was what you actually saw.
The dome now tints AND crushes (a lerp alone lands #717273: it runs in linear
space and the texture is baked near-white). Stops at 0.78 because the yard has no
lights and a storm you can't see is a black screen. Lightning now lights the
cloud it's inside (#3e3e3f -> #d4ddf2), and fires on the biggest gusts via
sky.lightningGustPow, not just the three authored strikes — driven off the
telegraph so the flash lands with the gust that earned it.
Also: c.test's storm list was hardcoded to two storms while the node runner globs
the directory, so storm_03 was untested in the browser half. Its own ponding
assert caught it.
Selftest 195/0/0 (was 184). Verified live: night reads as night, flash lights the
cloud, exposure responds.

Pond (SPRINT4 §E-1, decision 10): pond_water.png and pond_normal.png, for a
patch Lane B builds from the cloth's own nodes — same ride-the-nodes rule as the
tears, since a rigid disc would sit still while the belly moves under it. Alpha
is a radial feather and RGB darkens toward the centre, both encoded radially so
the shading survives being scaled per pondMass (radius ~ sqrt(mass)). Water is
grey-green, not blue: rain caught in a sail is shallow, murky and mirrors an
overcast sky.
Both at 256², not 512²: smooth low-frequency content, and at 512 they were
256 KB + 320 KB against ~20 KB for every other texture here. The chop is seven
waves at golden-angle directions rather than three crossed sines, which
interfered into a lattice and read as basketweave; the normal map gets six
integer-frequency waves for the same reason, and still asserts its own tiling.
broom_01 (§E-2): poke_tip sits on the bristle end deliberately — a broomstick
jabbed at a loaded sail holes it.
Renames fence_panel_broken to fence_panel_snapped to match SPRINT4 §A-4/§E-3.
Lane A's dress() guards every load, so the mismatch would not have crashed —
the wreckage would silently never have appeared, which is worse.
All 21 assets pass, 33 output files byte-identical across two runs, 186/0/0.

The 60% bar passes on the real yard at every value tested. My
"unachievable" verdict was measured against a 16.7-degree reference rig
the game cannot build; the yard is 4.8 degrees, where it clears easily.
Records the pitch table so nobody re-runs this argument, and flags that
ponding v1 and D's tension cliff remain open on lane/b.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Re-measured on A's dressed yard. The bar clears at every value tested —
67% at the landed 0.12, 84% at 0.40, 85% at 0.45 — and the twisted rig
holds 4/4 at all three. storm_02 downdraftOfTotal 0.12 -> 0.45 per
decision 11. Both physics gates now close on the same storm JSON.
My "mathematically unachievable" claim was wrong, and the algebra says
exactly why: ratio = (f / (sin p + cos p·f))^2 depends on the REFERENCE
PITCH far more than on the downdraft. My synthetic reference was pitched
16.7 deg, where the bar genuinely is unreachable (asymptote 109%, needs
f=0.86). The yard is pitched 4.8 deg — house fascia 2.60 m to posts
3.95 m over ~16 m — where 0.45 gives 72% on paper and 85% measured. The
equation was right and the rig was fiction: I was measuring against a
sail the game cannot build. The integrator's "measured beats modelled"
call was correct, and C's 0.45 was right on the geometry that ships.
The assert now derives its reference from the yard's real pitch and says
so, with the pitch table in a comment, so the next person to touch this
can see in ten seconds why the number moves.
Also re-pointed §7's twisted rig off the 145 m2 quad decision 2 retired
onto a real 23 m2 one ('t1,p1,p2,p3', most twisted in the 18-45 band).
The repair leg's dodgy carabiner moves to p2: measured peaks are t1 2.43
/ p2 2.35 / p3 0.82 / p1 0.60 kN, and it had been sitting on p1 — the
lightest corner — so it rode out the storm and the leg skipped. It now
blows and one repair finishes 4/4. Removed its stale skip guard, which
still tested the old gusts.downdraft key.

Semantic done + both-gates measurements + the finding that A's anchors alone
don't unblock 0.45 (B's §7 rig is still 141 m²). storm_02 held at 0.12 to keep
main green until B re-points to a small quad.

Verified all Sprint 3 weather work through the real game (SHADES.step) and a
node harness, never the demo. The game hosts the full storm, and a second
weather harness only drifts (hardcoded yard, mock sail). Sprint 2 item 6.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The gust-only downdraft could not satisfy B's 60% no-free-lunch bar and the §7
twisted-survives gate together: the downdraft peaked at the gust peak, where
the horizontal peaked too, so a flat sail never reached 60% of a pitched one's
load without a spike so violent it also broke the twisted rig. The integrator
measured the pincer (0.58 -> 48% and still breaks twisted).
Fix: the downdraft is now a fraction of the LOCAL total wind speed, not of gust
power (weather.core verticalAt = -frac * localHoriz). It presses a flat roof
steadily across the whole storm — peak total 32.6 m/s dwarfs peak gust power
12.6 — so the ratio clears 60% at a gentle fraction, with no gust-peak spike.
It rides the local speed, so a tree's wind shadow shelters from falling air too.
speedAt() stays horizontal (a wind meter doesn't read falling air).
Field renamed downdraft -> downdraftOfTotal; the validator rejects the old name
rather than silently re-meaning it. The vertical now carries NO rng draws at
all, so the determinism guarantee (tuning can't re-time gusts) is structural,
not just separate-stream.
Measured both gates myself with B's SailRig (8-direction flat-vs-pitched sweep +
§7 legs). Target for storm_02 is 0.45: 69% of-max / 60% worst-heading on the
bar, twisted rated rig survives with ~21% margin. HELD at 0.12 this commit —
the current yard's only twisted quad ('h1,t2,p1,t1', ~190 m2) starts losing a
corner near 0.15 in the exact solver, so 0.45 would red B's §7. 0.12 ~= the old
gust-only 0.3 in peak downdraft (-4.2 vs -4.5 m/s). Bump to 0.45 is a one-number
joint step once A lands decision-2 anchors (18-45 m2 quads) and B re-points §7.
storm_03_southerly: campaign ramp between gentle and wildnight — peak gust 21
m/s, sustained 13, one moderate southerly change. Auto-swept by the suite.
Selftest 170/0/0 (all three §7 legs green). Verified live: downdraft/horizontal
ratio is exactly 0.12 in-game, rain occlusion still covers the bed.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The §7 loop is closed by hand on the merged game: pick up a spare at the shed,
carry it across the storm, the carabiner weak-link blows on its own, chase the
flogging corner (prompt tracks it live), hold-E re-rig → 4/4, ride out → survives
with full coverage. Definition of done met with a real storm break, not induced.
Also logged for B+C: the sail's failure envelope is a cliff — 4/4 up to tn 1.03
(~1.2kN peaks), instant ~10kN double-cascade at tn 1.04. Good rigs survive, flat
rigs cascade; the thesis holds and the decision-8 downdraft semantic won't move
the cliff (it's a cloth-stability ceiling). Ladder stretch goal deferred to
Sprint 4 with reasoning — it's a second carry type + placement + code-driven
climb height, bigger than what's left of this sprint.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Implemented and swept fraction-of-total downdraft: it pincers exactly
like gust-only did. The cause is not the semantics, it's the bar. A
pitched sail's normal is still 96% vertical, so a downdraft loads it too,
and on its worst heading pitch and downdraft add: |d| = 0.287 + 0.958f
against the horizontal sail's f. The ratio asymptotes at 109% and needs
f=0.86 (28 m/s of falling air) to reach 60%. No value works under any
semantics.
Recommend retiring it as a wind problem. DESIGN.md's own answer is
ponding, and the arithmetic dwarfs wind (1250 kg vs 8 kg of fabric vs
1 kN of wind) — but it can't bite in 90 s without a ~40x time-compression
fiat, so it's an M4 item with an owner, not a Sprint 3 fix.

Records the measured before/after for Lane B (their pre-tension cascade is gone),
and flags that full bed coverage costing >=59 m2 is deliberate design rather than
a tuning miss — with an assert in both directions so nobody optimises the
tradeoff away by accident.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Posts pulled in to (-4.5,5.5)/(4.0,6.0) with p3 at (0,7), and dress() now swaps
Lane E's house_yardside and both gum trees over the graybox, adopting their baked
anchors rather than my constants (decision 6). E's fascia sits at x=-3..3, not my
guessed -5..5 — narrowing the house span by 4 m is a real part of why small quads
exist at all.
Every anchor now carries E's rating_hint: fascia 0.35 with collateral "gutter"
(they encoded DESIGN.md's "the fascia board is a lie" straight into the asset),
tree branches descending 1.0/0.88/0.76 from fork to thin limb. branch_anchor_01
keeps the t1/t2 ids so nothing referencing them breaks; the rest are added.
The yard went from 7 anchors offering nothing under 110 m² to 11 offering 34
quads in the 18-45 m² band, 8 of which shade a quarter of the bed or more.
Measured through the same storm_02: the big house-to-post span loses its
carabiner at t=3.7 s and cascades to 2/4, while a 37.7 m² tree-to-post rig at
0.85 tension survives all 90 s intact and shades 58% of the bed. That is
DESIGN.md's thesis finally standing up in the yard rather than in a doc.
Lane B's "cascade at t=0.4 s from pre-tension alone" is gone: calm peaks are now
634 N (big) and 200 N (small) against a 1200 N carabiner, and no rig breaks
before the storm starts.
Two asserts pin it, because both halves are easy to lose by accident: at least 3
riggable quads in 18-45 m² must shade the bed, AND full bed coverage must stay
above 45 m² — if a small quad ever covers the whole bed, the rigging puzzle has
no wrong answers left. Selftest 172/0/0.

E's recipe verbatim: grid (i,j) -> (u,v), repeat 6x6, sRGB. Without the
uv attribute three defaults every vertex to (0,0), the map samples one
texel and the membrane reads as flat colour — which looks like the
texture failing rather than like a bug, so E flagged it ahead of time.
Texture URL resolves against import.meta.url rather than the server root,
same as weather.js's STORM_DIR and the same thing the integrator's
/world/ -> relative pass was fixing. A missing texture warns and falls
back to flat colour instead of throwing: the cloth is the game, the weave
is a finish, and it must not be able to take the sail down.
Added anisotropy 4 — the sail is mostly viewed at a raking angle from
underneath, which is exactly where an unfiltered weave turns to moire.

Booted merged main and looked at Lane A's dress(): shed and workbench are

The pre-merge thresholds were tuned against a mock that injected +18 gusts. In
the actual storm_02, gusts-over-baseline peak at 12.1 m/s — so stumbleGust:17
was above every gust in the game and StumbleBack was unreachable dead code, and
shoveGustMin:8 (a low bar in the prototype's 12-38 units) had become a high bar
in ours and threw away most of the shove.
Retuned against the real storm profile (12 gust events, peaks 12.1..6.1, 4
knockdowns, maxExposure 1.55): stumbleGust 17→9, shoveGustMin 8→4. A wild night
now reads shoved (26s of 90) → stumbling (4) → floored (2); a calm day stays 0/0.
d.test.js now loads the real storm JSON via weather.loadStorm and asserts every
threshold is REACHABLE and correctly ordered — the guard the first tuning lacked.
This matters because decision 8 (B+C) reweights the downdraft this sprint, which
is exactly the kind of change that silently killed StumbleBack the first time.
Also pinned the emergent 'unbrace into a gust → stumble' behaviour.

The aftermath screen needs something to point at (SPRINT3 §Lane E-2).
garden_gnome_01_broken snaps at the ankles with the base left where the player
last saw him, head rolled clear with the beard still on, hat off — recognisably
him rather than a shattered pile, because wreckage nobody can identify is just
gravel. fence_panel_broken loses a few palings and hangs one off a nail; most of
it stays standing, which is what makes the hole read as damage rather than as a
design choice. Both keep their intact twin's origin and ground plane so Lane A
swaps mesh-for-mesh with no offsets, asserted both ways.
Also asserts something claimed since Sprint 1 and never checked: that glTF
extras reach three's userData. They do — the gnome's collateral_value, the
canopy's sway_amp, branch_anchor rating_hint and the bin's mass_hint all arrive
as numbers. Had that silently dropped, Lane A's gnome would score $0 and every
anchor would rate identical, which reads as a gameplay decision rather than a
missing field.
Contact-sheet framing now keys the capsule off height, not max(dims): the broken
gnome is 0.39 m across but stands 0.11, so spread-based framing buried it the
same way it once buried the shackle.
Selftest 175/0/0, 30 output files byte-identical across two runs.

Also records the KeyboardInput.holding getter trap: assigning to it from a probe

SPRINT3 decision 9 / §Lane A.1. Lane D's §7 loop — rig, carry a spare, repair
mid-storm — had nowhere to pick a spare up, so wireYardActions self-skipped the
pickup and nothing in the game could put one in your hands.
world.shedTable.pos is published synchronously from constants even though the
meshes arrive later: createWorld() has to stay sync (a.test.js and the selftest
build a yard with no server), and wireYardActions reads the position at wiring
time. dress() then refines it onto Lane E's baked pickup_anchor — which moved it
5 cm off my guess at where a table top is, so it was worth reading.
dress() is async and separate from createWorld for the same reason: a fetch in
the constructor would make the selftest slow and flaky, or break it. Each load is
guarded individually, so a missing GLB leaves its graybox standing instead of
taking the boot down.
Verified by hand rather than by registration check: walk up, hold E, spare in
hand; a second hold says "hands full"; leaning on the table with E held for 6 s
deals exactly one spare (D's latch works); nothing fires from across the yard.
Selftest 169/0/0.

The --only runs during the sprint left a partial sheet committed. Also fills the
empty slots in a partly-filled last row with the background sampled from a
tile's corner, so 19 assets in a 4x5 grid no longer leaves a black hole. The
world colour can't be reused for this — the render is sRGB-encoded, the scene

rake_pivot shipped as a childless empty, so rotating it moved nothing — and
rotating the whole GLB instead, which is the only alternative, tips the concrete
footing out of the ground along with the post. DESIGN.md makes raking away from
the load a player decision, so the handle has to actually work.
It now holds post + pad_eye + top_anchor, with footing left on the root: rake it
8° and the post leans while the concrete stays planted. Asserted both directions
in e.test.js — the head must travel over 0.3 m and the footing under 0.01.
Same class as the canopy bug, found the same way: by driving the handle in a
test instead of eyeballing the model. Exported dims unchanged.

Textures (SPRINT2 §Lane E-2). sail_weave.png is a seamless 512² knitted
shade-cloth weave with the stripe banding real cloth has; the script proves the
wrap by evaluating a second tile and requiring an exact match, because Lane B is
being told to set RepeatWrapping and a bad wrap would seam across the whole
sail. Luminance rides in a narrow band so it multiplies the base colour instead
of replacing it — high contrast reads as burlap, not HDPE. Dropped the per-pixel
noise: invisible at ±0.012 and incompressible, it cost 305 KB of the 323.
sail_tears.png is a strip of 4 escalating rips. Each is a lens, not a slit —
fabric under tension parts widest in the middle and tapers to a point, and a
constant-width gap reads as a drawn line. Threads bridge the gap, scaled to the
local width; without them a dark lens is a hole rather than a tear.
Dressing (§Lane E-3): wheelie_bin_01 (240 L, 12 kg, `lid` on its own node so it
flaps before the bin goes over), washing_line_01 (a Hills Hoist — the `head`
freewheels, giving a second wind tell at head height), garden_gnome_01
(collateral bait: a smashed gnome reads where a damage number doesn't).
Bin and tramp land in models/debris/ for Lane C to glob. All 19 assets pass, 28

world.js sways a tree by rotating a `canopy` group whose origin sits at the
trunk top, so the blobs swing about the trunk. The trees shipped canopy_01..03
as siblings of `trunk` with each origin at its own blob centre — rotating one
spins a sphere in place, which is visually nothing. Lane A could not have swayed
these trees, and the canopy lean is the gust telegraph the player reads a beat
before it hits the sail, so the tell would have gone missing rather than looked
wrong.
Adds the `canopy` empty at the trunk top with the blobs parented under it, so
A's existing code works unchanged, plus sway_amp / sway_phase / sway_pivot_y
for the per-tree tuning SPRINT2 §Lane E asks for (gum_01 is big and leans less
at 0.85; gum_02 is whippy at 1.20 and shows a gust first).
sway_phase draws from its own RNG stream: taking it from the shared one would
consume a value and shift every blob draw after it, resilhouetting a tree the
other lanes have already tuned against. Exported dims are identical to Sprint 1.
e.test.js asserts the pivot by rotating the handle and measuring that a blob
actually travels — red before this change, green after.

Decision 3 doesn't clear its own 60% bar: measured against lane/c over 8
headings and the full 90 s, flat-horizontal is 34% of flat-pitched, not
>=60%. The downdraft is 0.3 of the GUST component only, so storm_02's
strongest is -4.5 m/s against a 32.6 m/s horizontal peak, and pressure
goes as v^2. Needs ~0.55-0.6, or a fraction of total speed.
Also flags for A: rig.step needs the 4th debris arg or crates fly through
the sail; and the cheap-rig cascade fires at t=0.4s from pre-tension on
the 192 m2 quad, which decision 2 fixes.

B-4. The gate used to run on my own stub wind — uniform, horizontal,
tuned by nobody — so it proved the cloth was self-consistent, not that
the game works. It now loads the shipped storm JSON and drives the cloth
through weather.core.js (pure and import-free, so the same path runs in
node and in selftest.html; weather.js's own loadStorm can't help because
its STORM_DIR is a file:// URL that node's fetch won't open).
All three halves of §7 now run on real storm_02 and the real yard:
a flat drum-tight carabiner rig cascades 4/4; a well-twisted mixed rig
holds all four; and a twisted rig with one dodgy corner blows it and
finishes 4/4 intact after a single repair — the DoD scenario, in an
assert.
Perf: Lane C added an `out` param to wind.sample specifically so sail.js
wouldn't allocate, and I wasn't passing it — 162 faces at 60 Hz is ~9.7k
throwaway Vector3s a second. Now passing a scratch vector. Stub winds
that ignore `out` still work; we read the return value.
Two tests skip rather than pass vacuously while Lane C's downdraft is
unmerged: a "nothing broke" repair scenario would go green forever and
check nothing. Both light up by themselves on merge, and the repair one
hard-fails if a downdraft IS present and still can't threaten the rig.

RiggingSession already held every rule and was tested headless; this is
only the hands. Click an anchor to rig it, click again to cycle its
hardware, shift-click to pull it off for a full refund, [ and ] for
tension, S for the spare. RMB is left alone — that's the camera's orbit.
Enter stays Lane A's: the phase machine calls commit(), which goes
through main.js's rigSail() door as A asked.
It renders its own anchor markers because the yard has none to raycast
against — world.js builds posts and trunks, not pick targets — and
marker styling is prep-phase UI, so it belongs to this lane.
What you click is not what you see: the marker ring's tube is 5 cm, which
at yard distance is a couple of pixels and genuinely unhittable. Picking
goes against an invisible 0.45 m sphere and the ring is just the read.
The panel shows live sail AREA, which SPRINT2 doesn't ask for but
decision 2 implies: the 70-192 m² problem is invisible to a player who
can't see what they're about to build. Picking the obvious quad
(h1/h3/p1/p2) now says "191 m2" before you commit to it.
dev_rigging.html follows the house pattern (C's weather_demo, D's
dev_player): the picking UI can't be asserted headless — it is clicks,
raycasts and materials — and can't run in index.html until A wires step
8. It boots the real world.js, real anchors and real cloth, so what's
verified is what ships. Retire it once index.html hosts prep.
Verified by hand in it: rig h2 by click, cycle carabiner -> shackle,
budget $80 -> $65, weak link flagged, dashed quad preview, commit ->
sail in scene (100 verts, 162 tris, casting a real shadow over the
garden bed) -> storm with corner loads reading 1.0-1.2 kN.

Stood in for world.shedTable and rig.repair/cornerPos in the live game and drove
the whole scenario through the real sim, real interact and real rig: take a
spare, carry it to a blown corner, hold to re-rig, spare consumed, corner back.
Lane D's half of gate 3 is done; the gap is two small seams, now specified with
working code rather than a request.
Selftest 136/0/0 across all five lanes (was 121) — no other suite moved.

Includes the controlled downdraft rebalance table for Lane B, the frozen
debris.pieces seam, and the garden-HP design question for Lane A (rain shadow
vs sun coverage).

The garden visibly stays dry under the sail. Rain arrives along the wind, so
the dry patch sits downwind of the cloth and slides across the yard as the
wind swings — at the southerly change it walks right off the bed, free drama
and honest physics.
Cheap on purpose. Ray-testing 3k drops against 162 triangles every frame is
~486k intersections for an effect nobody inspects closely. Instead project the
sail's triangles ALONG the rain onto the ground into a coarse height grid, a
few times a second (the cloth moves slowly next to the rain); per-drop cost is
one grid read, and occluded drops get a zero-scale matrix rather than a
raycast. Measured 0.041 ms/rebuild, 10x/s = 0.41 ms/s against A's 0.63 ms
frame — negligible. Reads rig.pos/rig.tris, so nothing new needed from Lane B.
Verified in the real game with a surviving twisted rated rig: 497 grid cells
covered, 96% of the garden bed under cover, live drops culled under the cloth
and falling in the open yard either side. Screenshot for DESIGN.md.
skyfx exposes rainShadowOver(rect) — NOT the same as rig.coverageOver(bed,
sunDir). That one is the SUN shadow; this is the RAIN shadow (down the wind).
Which drives garden HP is a design call — flagged for A in THREADS.
Selftest 134/0/0 (8 new rain-shadow asserts).

At gate 1 the ped walked straight through the house. Collision now stops it
0.30 m off the wall face (expected -9.70, measured -9.70), off trunks, posts and
the fence, and slides along a wall hit at an angle. Injected as opts.collide the
way groundAt already was, so player.sim.js stays zero-import and node-runnable.
Two things the real yard taught, neither guessable from the plan:
- `fence` is a GROUP of 37 child meshes whose combined box is the entire 30x20 m
yard, so one box per solids entry is useless. Flattened to 43 leaf boxes.
- the house ROOF spans y 2.99-3.21 and reaches 0.4 m FURTHER into the yard than
the wall under it (eaves overhang). A flat footprint test would stop a 1.7 m
person dead at an invisible eave, so every box is filtered by vertical overlap
with the body and the roof drops out on its own.
Boxes are built once (solids are static) and distance-pruned — no per-frame
raycast, which is the thing Lane A measured as catastrophic on the terrain.
The M3 pack is wired: carrying swaps locomotion to Carry/CarryIdle; an
interaction names its own verb through a new `clip` field on the interact spec
(Crank at a turnbuckle, PickUp at the shed table); StumbleBack fires on a gust
that breaks your stride but can't floor you — below knockWind on purpose, so a
storm reads as shoved → stumbling → floored rather than fine-fine-fine-flat.
TakeCover (hold C) became a real mechanic rather than a pose: brace and knockWind
x2.0, shove x0.25. A 38 m/s gale floors you standing and doesn't while braced;
let go in the same gale and you're down in half a second. It raises the bar, it
does not remove it — a big enough gust still wins, braced or not. So the storm's
answer to "the gusts are too strong to cross the yard" is now wait one out and
move in the lull, which is the repair-window language DESIGN.md already uses.
wireYardActions now reads sailRig.corners[i] live by index instead of capturing
the corner object — per Lane A's warning that attach() replaces the array, a
captured corner is one the sim no longer steps and would gate forever on a
`broken` flag that can never change again.
35 Lane D asserts, 0 fail (was 20). Carry/shelter/knockdown verified against the
real 17-clip pack in the assembled game, not only in the harness.

SPRINT2 decisions 3 and 5, plus Lane A's fog nit.
Decision 3 — gusts now descend. Cloth pressure goes with dot(wind, normal); a
flat panel's normal points at the sky, so in a perfectly horizontal wind the
dot is ~0 and "lie it flat and ignore the storm" was the cheapest winning rig.
A gust front is descending air, not just faster air. Per-gust downdraft
fraction in storm JSON (storm_02 0.3, storm_01 0.18, default 0.25, validated
0..1), each gust varying 0.6-1.4x. Peak downdraft in storm_02 is 4.4 m/s, 17%
of the horizontal. Lane B: the cloth-side assert is yours.
The vertical draws from its OWN rng stream, and there's an assert pinning
that: pulling it from the main stream would shift every subsequent (t0, pow)
and silently re-time storms Lane A has already hand-verified. Their carabiner
still blows at t=45.4 and cascades at t=56.
speedAt() stays horizontal — an anemometer doesn't read falling air, and a
wind meter that spikes because a gust is descending reads as a bug.
Decision 5 — debris.pieces frozen and documented in contracts.js as the seam
Lane B reads in sail.step(), with the sphere/SI/mutated-in-place semantics
spelled out and an assert tying the live shape to the contract table.
Fog: dispose() captured scene.fog by reference and step() mutates that object
in place, so restoring it restored nothing (Lane A caught it). Now captured by
value, and fog we created ourselves is removed rather than left behind.
Selftest 130/0/0 (was 121); Lane C 28 asserts.

Decision 4 — conform to Lane D's call sites rather than the reverse (D
landed first and duck-typed them): repair(i), trim(i, delta) and
cornerPos(i). repair takes no hardware argument because prep sells
exactly one kind of spare, so it re-rigs at shackle grade — an upgrade
on a blown carabiner, a downgrade on a blown rated shackle, which is the
prototype's behaviour and a real choice about which corner you run to.
cornerPos returns a fresh vector at the live node, so a blown corner's
prompt chases the flogging corner instead of sitting on a dead anchor
(measured: 13 m off). All three are contract entries now, not PROPOSED
comments, so the merge tripwire enforces the seam.
Decision 5 — sail.step() takes an optional debris and applies sphere-vs-
cloth impulses. The exchange is symmetric: every newton-second the cloth
takes out of a crate, the crate loses. Asserted, and it conserves to
0.000% on an interior hit. Pinned corners are the deliberate exception —
invMass 0 means a crate off a corner dumps its momentum into the house,
which is correct, the anchor is bolted to a wall.
Note this leaves debris.js's applyToSail dead: it guards on `sail.nodes`,
which never existed on the rig — the cloth stores Float64Arrays. So the
debris-vs-sail impulse has been silently doing nothing in the assembled
game. Decision 5 puts it on this side; flagged for Lane C in THREADS.
The contact radius is swept by the piece's travel because main.js steps
the sail before the debris (so piece positions are a frame stale) and a
0.3 m crate at 25 m/s covers 0.42 m per frame — enough to pass clean
between cloth nodes.
Also: coverageOver() rays now start at heightAt(x,z) rather than y=0.

Also records what the assembly turned up for the other lanes: the rigSail() door
Lane B's picking adapter must come through, the knockdown(t, ...) argument order
that would have silently broken Lane D's get-up, and the evidence for Lane C's
dispose() light-restoration ask.
