Each limb was one straight uniform tube — a peg poking out of a pole, and the
most visible art problem in docs/yard_day.jpg. They now leave the trunk thick,
sweep up on a bezier and taper to nothing, which is what a gum does. +96 tris on
gum_01, silhouette bounds unchanged.
Nothing physical moved. The tip is a bezier endpoint and the four rng draws per
branch are the same four in the same order, so every branch_anchor_* is
bit-for-bit where it was — verified before and after, all five identical to 6dp.
Lane A's winning line rigs off t2 and is untouched; no balance number can shift.
e.test.js now hard-codes those five world positions as a tripwire, so no future
art change of mine can quietly invalidate a sprint of someone else's physics. If
it goes red, the art moved an anchor — fix the art, not the numbers.
Card text and the dawn-tint treatment go to Lane A in THREADS. The tint is a CSS
snippet rather than a ninth texture: only two of my eight are consumed, and a
full-screen gradient needs no asset at all.

THE CAUSE, and it is not a winner: balance.test.js built skyfx with no camera,
and skyfx.step() opens `if (!camera) return;` — so the hail shadow grid was
never rebuilt across all 5400 calls and every loadout was scored as though it
had no sail. hp 36 IS the bare-bed number. Measured with the camera as the only
variable: hailShadowOver(bed) peaks 0.000 vs 1.000, hp 36 vs 69. Neither harness
was lying; one was flying a yard with no cloth in it. Camera + wind shelters
added — the suite must drive what the game drives.
MY ERROR, named: the hp-58 win was measured at tension 1.0 and I never declared
it. At the shop's default 0.9 my own end-to-end also loses 2 corners.
STILL OPEN: this suite says 2 corners lost, my end-to-end says 1 at tension 1.0.
Ruled out by measurement, each worth <=0.02 kN: shelters, frozen vs live tree
sway, the scripted repair. Next suspects named in the skip: session.commit() vs
rigSail(), and main.js passing debris as rig.step's 4th arg (debris ADDS load,
so it should break MORE here, not less — that inversion is the thread).
And the find that explains how this survived a merge: Suite.test() ignored its
return value, so `return "SKIPPED — ..."` was recorded as a PASS. The
integrator's storm_02 skip was a fake pass; so was mine for storm_01; `skip: 0`
in every report we ever printed was the tell and nobody read it, me included — I
misread one of those fakes as my win reproducing. test() now honours the string,
and rejects async fns outright (they hand back a Promise that cannot throw
synchronously, passing forever while proving nothing).
That guard immediately caught its own author: BOTH my wind-router tripwire tests
were async and have asserted nothing for two sprints — including the sprint where
I reported the tripwire "caught its first real omission". It had, in a hand-run
probe, never in the suite. Awaits hoisted into run(); they asserted for the first
time today, and pass.
Selftest 261 pass / 0 fail / 2 honest skips.

hide_render does not survive glTF export — verified in three r175, every node
arrives visible:true. So garden_bed has been drawing plants_full, tattered AND
dead superimposed since Sprint 1, and my THREADS note told Lane A the opposite.
The asserts missed it by checking the nodes existed rather than that only one
was on. The flag now rides in extras, which does export, and consumers apply it
in one line; e.test.js pins the flag instead of the node.
Night dressing: house_yardside gains window_glow, an unlit emissive pane marked
hidden_by_default, plus window_light_anchor. A warm window means someone is
inside, which is why the player is out in the dark keeping the sail on. Plus a
moon sprite whose halo, not its disc, is the part that survives cloud.
End cards are rendered from the game's own props as a diptych: identical camera
and yard, only the night's outcome differs. The left third is left empty for
Lane A's text.
Cards are opt-in behind --cards because EEVEE's shadow pass is not
byte-reproducible across processes in 5.1 — proven with a minimal repro, not
PYTHONHASHSEED, and present even with a hard sun. The dawn shadow is the art, so
the cards become committed art rather than build output. Everything the game
loads stays byte-identical: 38/38 verified.

The gate asks the only question no per-lane suite can: can the night be
won through the real $80 shop. It buys loadouts via RiggingSession, flies
the real storm JSON over the real yard, integrates skyfx's real hail/rain
exposure into main.js's real garden drain, and judges with main.js's own
win rule.
Status: storm_01 warm-up PASS, cheap-rig-punished PASS, decision-13
miss-the-bed control PASS, and **storm_02's winnable line FAILS** at
hp=36, 2/4 lost. That reproduces the integrator's finding exactly and is
the gate doing its job — SPRINT6 says everything waits on gate 1.
Two things I got wrong on the way, both worth the comments they now
carry:
- The first draft hardcoded the anchor table from a THREADS entry and
was badly wrong (the dressed yard has the house at x=±3, not ±5). It
flew a fictional yard. It now reads the yard from world.js and freezes
only the sway — the yard IS the balance, so it cannot be a copy. Same
failure as Sprint 3's 16.7° reference rig.
- The asserts were async. testkit's Suite.test() calls fn() WITHOUT
awaiting, so every one would have passed forever while proving nothing
— the exact vacuous-test pattern I've flagged three times. Storms are
now flown up front in run() (which runAll does await) and the asserts
are synchronous judgements over the results.
Registers as a sixth 'BAL' entry in selftest.html. A: your "nobody
touches this file" rule guards against five lanes conflicting here; one
jointly-owned entry is the case it makes room for. Revert if you disagree.

Variants for A's five-night week. Each gets ONE new trick, and neither is
"the same storm but harder":
- storm_03b_earlybuster (night 3): same force as storm_03 (21 m/s gust, 13
sustained) but the change lands at t=18 instead of t=30. You rig for a hot
NW'er and get a southerly a third of the way in. Tests timing, not budget.
- storm_02b_icenight (night 5): LESS wind than the wild night (28 vs 32 gust,
19 vs 20 sustained) and 2.8× the hail — 32 hail-seconds vs 11.4, held 26 s
straight across the change, size 1.4 stones, ice on every gust ≥9. Hail is
the score (decision 13), so this asks the one question storm_02 only asks
for nine seconds: is the bed actually covered, and does the cover hold? A rig
that survives storm_02 by hiding in a small quad off the bed loses here.
Week escalation now reads 11.3 / 21.4 / 21.2 / 32.3 / 28.3 m/s peak gust with
0 / 2.4 / 2.4 / 11.4 / 32.0 hail-seconds — force ramps then plateaus while the
question changes underneath it.
Forecast uncertainty (DESIGN.md partial-information canon): `forecastFor(def,
lead)` + `stormStats(def)`, pure functions on a def rather than methods on the
wind — the card holds defs, doesn't want a field, and this keeps forecasting
off the wind contract and out of A's router. Bands widen with lead and resolve
to the exact truth at lead 0; deterministic per storm, so re-reading the card
can't reroll it.
The invariant, asserted across every storm at five leads: a band ALWAYS
contains the truth. That's the line between partial information and a lie — a
player who rigs for the top of the stated range must never be ambushed.
stormStats also measures what the card was estimating: storm_02 gusts to 32.3
m/s, not the 30 that `baseCurve peak + powBase + powRamp` implied.

Rebuilt the broom against B's FROZEN contract, which is not the shape I asked
for and is better: pondCentroid() (one pond, not a list — B's belly pools into a
single heaviest place) and drainPondAt(node, dt, radius) draining PER FRAME and
returning the kg shed that call. Added interact `onHold` for actions that do work
over the hold rather than at the end of it; the total is only knowable by
accumulating. Falls out nicely: an interrupted poke sheds only what it got
through, which is the honest rule.
Calibration, measured on B's live sim rather than modelled (flat rig, storm_02,
pond mass at poke → kg shed → outcome):
8s · 85 kg → 76 shed → wet (caught it before the ticker)
12s · 152 kg → 104 shed → stagger (you answered the warning)
20s · 281 kg → 182 shed → knocked (you ignored it)
Bands sit under those so all three are REACHABLE — my Sprint-5 guesses (60/120)
would have flattened the player on every poke, and my first pass at real numbers
(150/350) put the knockdown above anything this rig can shed, i.e. dead code.
That is the StumbleBack lesson exactly, so d.test.js guards reachability with the
measured numbers and will fail loudly when gate 1 moves pond masses.
Bug the live sim found that no stub could: a loaded belly SAGS toward you — real
ponds ride from y=1.2 down through y=-1.0 — and my reach gate rejected `up < 0`,
so the broom answered "nothing pooling here" with 281 kg hanging over the garden.
Sagging toward you is the mechanic working. Gate is now a physical band between
sagFloor and reach, with the floor set between two measured cases: a live 281 kg
belly at y=-0.8 (pokeable) and post-tear wreckage at y=-4.5 (nothing to poke).

SPRINT6 gate 1's anchor lever, placed by measurement rather than by guess.
The wild night had no winnable line for a geometric reason: every anchor near
the bed (p1/p2/p3) is SOUTH of it, and nothing stands north short of the house
10 m away. So covering rigs had to span the yard and died, while rigs small
enough to survive sat beside the bed rather than over it. p4 supplies the
missing north-west corner.
Its position is swept, not chosen. Against the smallest quad covering 90% of the
bed: (-2.2,-1.2) → 44.4 m², (-3.2,-1.2) → 48.6, (-3.2,-2.0) → 51.7, beyond
z=-4 → no effect at all. Pulling it inward to 44.4 would put full coverage
INSIDE the survivable band and collapse DESIGN.md's central tension — covering
the bed has to cost risk. a.test.js's >45 m² floor is what shouts if anyone
moves it in. With the 8° rake the top anchor lands at (-3.72, -1.40), and full
coverage costs 51.6 m² against 63.5 before: a real new option, 19% cheaper,
still bigger than the 23-38 m² rigs that survive unaided.
Measured through the real $80 shop: t2+p3+p4+t2b, four shackles and a spare
($75), ends hp 58 with 1 corner lost — a WIN, where before every covering rig
lost 2-3 corners and ended at 36%. Hail damage falls 51 → 34 HP versus an
uncovered rig, so decision 13 is visibly doing its job.
Selftest 244/0/0; both yard tensions still green.

The aftermath was lying. Any run under 50 hp read "the rain found what you
skimped on" — including Lane B's twisted quad that holds 4/4 corners and skimps
on nothing. The verdict is the game's entire feedback channel: DESIGN.md wants
every disaster to replay as "…the shackle, I knew about the shackle", and
blaming the wrong thing teaches the opposite of the lesson the storm just spent
90 seconds giving.
The garden now keeps its damage split by cause, because the caller was pre-summing
hail and rain into one number and that sum is exactly the information the verdict
needs and can never recover afterwards. A garden that only knows it went 100 → 39
cannot tell a player whether their hardware let go or their perfectly-held sail
simply wasn't over the bed — opposite mistakes, opposite fixes.
verdictFor() is pure and lifted to module scope so it can be asserted directly.
It picks from modes the run can PROVE: cascade (naming the weakest link as going
first, not whichever was listed first), single corner, uncovered, rain, broomed,
ponded, clean. The integrator's exact case now reads "THE GARDEN IS GONE — and
every corner held. The hail fell where your sail wasn't."
Aftermath also gains decision 13's headline: "51 HP to hail, 13 to rain".
Verified live on the reported scenario, not just in asserts. Selftest 244/0/0.

Rain honestly walks under a sail (a droplet's terminal velocity is ~9 m/s, so a
30 m/s crosswind blows it in at ~73° off vertical), which is why a perfect rig
scored 54% garden vs 48% for no rig at all. Hail is dense: terminal ~22 m/s, and
a dense stone couples weakly to the crosswind, so even a gale leans it ≤20°.
Steep hail is blocked by overhead cloth, so the garden score becomes
rig-responsive without faking the rain physics — and it was always DESIGN.md
canon (hail shreds gardens; drainage answers rain, later).
weather.core: `hail` block in storm JSON — authored bursts (envelopes) plus one
synced to every gust at/above `withGustsAbove`, so the biggest gusts arrive WITH
ice. `hailAt(t)` (max over live bursts), `hailSize`, validator. Gust-synced
bursts key off the deterministic gust timeline and draw ZERO randomness, so
tuning hail can't re-time the storm — asserted, same guarantee as the downdraft.
storm_02 bursts on the southerly change (peak 1.0 at t=56.5, 11.4 hail-seconds);
storm_03 a mild 0.5; storm_01 none.
skyfx: `hailVelocity` (steep, ≤20° lean, terminal-velocity reasoning cited so
nobody re-opens the rain-angle argument), a second RainShadow fed the steep
vector, `gardenHailExposure(bed, t)` in the gardenExposure mold (A wires the
drain), instanced falling stones (hidden under the cloth so you SEE the sail
working), and hail audio: ground clatter that fades as the sail intercepts, plus
the cloth DRUM that rises exactly as the sail catches hail — the "my sail is
earning its money" sound.
Decision-13 gate proven: no-sail garden takes 4.4× the hail of a bed under a
good rig over a full storm_02 (bar is ≥2×), through the real gardenHailExposure
and B's SailRig. Verified live too (router-patched): stones fall visibly steeper
than the rain beside them, and a bed-covering rig cuts hail exposure roughly in
half at the burst.

Hail (SPRINT5 §E-1) ships two ways because Lane C's rain is a BoxGeometry with a
flat material and skyfx loads no external texture at all: hail_stone_01 as
geometry that drops into their existing InstancedMesh pattern, and hail_pips.png
as a 4-cell atlas for impacts. A flat quad can't be round and an impact is round
— that's the only reason the atlas is a texture. Both come with a copy-paste
recipe, because a grep showed exactly one of my five shipped textures is
consumed: sail_weave, the one I wrote a recipe for. grass_atlas has sat
unreferenced for four sprints.
plant_shred (§E-2) is elongated after the first pass came out radial and read as
green potatoes — it's the long axis plus the midrib that says "leaf".
tools/yardshot/ finally lands the DESIGN.md pictures, carried since Sprint 2. It
does NOT touch server.py or main.js: it's a Lane E stdlib server that serves the
repo and takes POST /shot, so the browser posts a Blob and bytes go straight to
disk instead of base64 through a console. do_POST is ~25 lines and Lane A is
welcome to lift it and delete this.
Three traps found on the way, all documented: toBlob is async so the WebGL buffer
is already cleared (toDataURL is sync); a backgrounded tab lays the canvas out at
0x0 and toDataURL then returns "data:,"; rAF is paused there so step() must be
driven by hand.

The broom (SPRINT5 §Lane D-1, DESIGN.md's funniest correct mechanic): a third
carry type that queues behind the same hands, walk under the sail belly, hold-E
poke (Crank per E's anim_hint) → B's drainPondAt() → the water lands ON YOU,
sized to the joke: splash under 15 kg, stagger over 60, flat on your back over
120. Everything defers to E's baked metadata (carry_type, poke_tip.use on the
bristle end, anim_hint) — read, not invented. Duck-typed against the ponds[] /
drainPondAt seam I posted to B early, so it carries/walks/refuses-thin-air today
and lights up fully the moment B lands ponding.
Self-wires from createPlayer like the ladder; needs the live sail rig, which it
reads off interact.sailRig (published by wireYardActions, which main.js re-calls
through rigSail whenever attach() swaps the rig).
Greyed prompts (§Lane D-2, my offer, A's HUD hook): interact.visible() shows the
nearest UNAVAILABLE action with its reason when nothing's usable, instead of the
prompt vanishing — the confusion I logged last sprint. nearest() (what hold-E
acts on) is unchanged, so display and action stay separate. step() now reports
`usable` so the HUD can grey the radial. Fixed the ladder-place label to read as
a reason too ("the fascia needs the ladder — it's by the shed").
broom.js keeps no top-level THREE import (the vendored addons need index.html's
importmap) so d.test.js stays headless; the view loads via dynamic import that
only fires in a browser. 217/0/0 (was 207), 13 new asserts.

The router is a hand-maintained delegation list and it has already cost us once:
when Lane C added rainMmPerHour/rainDepthMm, it didn't forward them, and nothing
went red — every suite holds a real wind, only the GAME holds the router. Lane B's
ponding would have passed every assert it had and done nothing in the yard; the
integrator caught it by hand at merge.
The class matters more than the instance. Sprint 5's headline system is Lane C's
hailAt(), and decision 13 hangs the whole garden score off it — the same silent
swallow would make rigging look irrelevant to the garden all over again, which is
the exact thing the sprint exists to fix. The assert diffs the router against a
real wind and names what's missing. Verified it fires rather than just passing:
rebuilt Sprint 4's pre-fix router and it reports exactly rainMmPerHour,
rainDepthMm.
Garden drain now goes through sky.gardenExposure() — same arithmetic, but it's
Lane C's term to own, and decision 13 extends precisely this shape, so hail lands
as one added term rather than a rewrite. Numbers unmoved: good rig 53%.
Also re-measured Sprint 4's headline finding against a TRUE control (fresh boot,
nothing ever rigged, shadow over bed 0.000) because my original control left the
previous round's sail in the shadow grid: no-sail is 48.5% vs a good rig's 53%.
The finding stands, and decision 13's premise with it.

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().

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.

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.

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"

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.

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.

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
output files byte-identical across two runs, selftest 129/0/0.

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.

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.

Rebased onto M0 and reconciled against the real spine. checkContract
('sailRig') now conforms and js/tests/b.test.js runs 28 asserts green.
Contract fixes:
- anchor.sway(t) is the ABSOLUTE position, not an offset (thanks A —
I had it adding sway to pos, which would have flung every
tree-anchored corner to double its coordinates).
- events is an Emitter emitting {type, corner}, not a drained array.
- coverageOver() rects are centre+size, matching world.gardenBed. It
consumes world.sunDir directly: a hit along sunDir means shaded.
- START_BUDGET/SPARE_COST/HARDWARE/FIXED_DT now come from contracts.js
rather than being redeclared here.
Bug: a corner that blew was marked broken but never had its mass
returned, so invMass stayed 0 and the "blown" corner sat welded in
mid-air — no flogging, and the sail silently went dead. PLAN3D §5-B
wants flogging emergent from the freed node, so _checkFailure now frees
it. The cascade test missed this because it called _repin() by hand;
the new test drives a real overload failure instead and asserts the
corner tears 2 m off its anchor and keeps moving.
Tension dial remapped from the prototype's rest/tension to a real
pre-strain. rest/tension asks for 17% strain at dial 1.2 and 29% at 1.4
— stretching an 18 m sail by three metres — and put 68 kN on a corner of
the yard's biggest quad with no wind blowing. At 0.10 strain-per-dial it
swings a 5x5 rig's peak load 2.1x loose-to-tight and redlines a 192 m2
quad at 8.3 kN drum-tight, which is punishing and correct.
HARDWARE ratings retuned in contracts.js to real newtons per the
standing note there that Lane B owns these numbers. Costs and tier shape
untouched; $80 still buys rated hardware on at most 2 of 4 corners.

player.sim.js Deterministic core, zero imports: camera-relative movement, the
state-machine table, wind slow/gust-shove/knockdown. step(dt,t)
is the whole clock — no Date.now, no Math.random, no rAF — so a
storm fast-forwards identically in selftest and in the game.
player.js The view: rig load per the 90sDJsim DEVMANUAL rig rules
(SkeletonUtils.clone, height-normalise off the MEASURED head
bone, canonicalised bone namespace), clip retarget, and
createPlayer() satisfying the Player contract.
interact.js Hold-E with radial progress + wireYardActions (re-rig 2.5 s,
turnbuckle trim 1.2 s, carry-one-item), duck-typed so it no-ops
cleanly until Lane B lands sailRig.repair/trim.
d.test.js 20 asserts in Lane A's harness: 38 pass / 3 skip overall.
Ported from the 2D prototype's shape (game.js:250-252), retuned to m/s: the
slow curve, and shove gated to gusts only and scaling with speed² so gusts have
teeth. Knockdown needs 0.5 s of SUSTAINED overload — deliberately the same rule
as a sail corner letting go, so cloth and people speak one language.
Two decisions worth the review:
- The knockdown pitches the root in code rather than playing the Falling clip's
root. Shared clips must drop Hips.quaternion (a different-orientation source
lays the target flat), so a clip physically cannot lie the body down. Doing it
in code also lets the fall go DOWNWIND of the gust that caused it, which a
canned clip could never do, and keeps it deterministic.
- Gust magnitude is recovered from a slow EMA of local wind rather than widening
Lane C's contract: wind.sample() gives the total and gustTelegraph() only fires
BEFORE a gust, so nothing reports gust size during the hold. The EMA
self-calibrates to whatever storm JSON Lane C authors.
Verified in a real scene, not only in asserts: head bone 1.715 m at fig scale
0.983, all six clips bound, walk/run at the tuned speeds, the body lies down and
gets back up, hold-E fires exactly once per press.

Replaces the skip stub with the checks Lane A's header asked for — every GLB
loads, is metre-scale with height on +Y, and keeps the nodes other lanes query
by name — plus anchor world-position and the garden bed's three damage states.
This catches what the Blender side structurally cannot: Blender exports
Z-up->Y-up and imports Y-up->Z-up, so a broken export_yup round-trips green.
A native glTF reader is the only thing that can prove the file.
GLTFLoader is imported dynamically on purpose. Three.js addons import the bare
specifier `three`, no page in the repo has an importmap yet, and selftest.html
turns an un-importable lane module into a hard FAIL — so a static import would
redden Lane A's merge gate over a harness gap rather than a real defect. It
skips with the fix instead, and lights up by itself once the importmap lands.
Verified behind a temporary probe first: 36/36 pass. Need logged in THREADS.

Three bugs the bench found once it was actually running a storm:
- Debris was glued to the floor. The scrape `v *= 0.86` ran every frame while
grounded, which is 0.86^60 per second — it pinned a 9 kg crate at 0.7 m/s in
a 19 m/s wind. Friction now applies on impact, with dt-scaled rolling
friction while resting. A crate crosses the whole yard at ~6 m/s.
- Debris slid instead of tumbling: wind is horizontal, so once down there was
no vertical force at all and it skated at constant height. Added tumbling
lift that flips sign as it rolls — bins hop now.
- The cloud dome had a dead straight seam across the sky. The fbm claimed to
tile and didn't; now each octave wraps at its own integer period.
Also: shelters and the bench now use Lane A's landed yard coords (t1 -9,2 /
t2 8,-2, gardenBed 1,2) instead of my guesses, so shelter tuning means
something.
Verified in-browser against a real storm: crate crosses the yard and the t=74
bin spawns from storm JSON; sail node shoved 0.32 m; a 14 kg bin at 20 m/s
knocks the player down and a tub drifting at 0.3 m/s correctly does not;
lightning peaks 0.88. Lane A's selftest: 37 pass / 3 skip.

debris.js: hand-rolled kinematic tumble, drag ∝ speed² so the gust that
spikes a corner is the one that launches the neighbour's bin. Ground bounce
via world.heightAt (contracts.js documents it as ours), sphere-vs-player
knockdown reported to Lane D, sphere-vs-sail-node impulse duck-typed so it
lights up when Lane B exposes nodes and stays silent until then.
skyfx.js: instanced rain that wraps around the camera rather than respawning,
storm sky + procedural cloud dome, lightning, and synthesized WebAudio layers
(wind bed, howl, rain, gust whoosh on the telegraph, rope creak off the worst
corner, flog when one blows). It modulates Lane A's lights and hands them back
on dispose() rather than owning them.
weather_demo.html: graybox bench to drive all three before M0 — mock sail,
storm scrub, 4x, throw-a-crate.
Aligned to contracts.js now that it has landed: relative three imports (there
is no importmap), contracts' rng() instead of a local copy, and storm paths
resolved off import.meta.url — server.py serves the repo root, so an absolute
/world/... would have 404'd at integration.
storm_02: fix the southerly change. contracts.js puts north at -Z and the wind
vector blows toward (cos d, sin d), so the old swing to +2.6 blew toward due
south — a northerly wearing a southerly's name. Now slews to -1.35: a SSW
buster off the open side of the yard, into the house.

Implements the contracts.js wind surface (PLAN3D §4): sample(pos,t) and
gustTelegraph(t), plus storm defs as data.
The prototype scheduled gusts by integrating (wind.gustT += dt). We can't:
sample(pos,t) is called by sail/player/debris/rain at arbitrary t, so gusts
are precomputed into a timeline from a seeded PRNG at load and read from t.
Envelope shape is a faithful port — telegraph 1.5s / ramp 0.8s / hold 1.7s /
fade 1.0s.
Maths lives in weather.core.js with zero imports (no THREE, no DOM, no
Date.now), so the determinism rule is structural and the suite runs in node
without waiting on Lane A's M0.
storm_01_gentle peaks at 11 m/s; storm_02_wildnight sustains 20 m/s and gusts
to 32 (BOM 'destructive'), with the southerly change landing just before the
worst of it — the corners that were slack all storm are the ones that cop it.
15 asserts green: telegraph lead >=1.2s, wind continuity in time and space,
storm JSON validator (incl. 14 deliberately-broken defs it must reject),
determinism, sample-order independence, tree wind shadow.

selftest.html only imports; each lane owns js/tests/<letter>.test.js. Five lanes
sharing one selftest.html would be the single guaranteed merge conflict in the
repo, so the stubs are pre-created with each lane's PLAN3D asserts written into
the header.
No rAF anywhere: it's throttled in a hidden tab, so a rAF-driven selftest would
pass only while you watch it. fixedLoop() drives time instead.
Lane A's suite covers the §5-A acceptance criteria, including "camera never
clips through house" — stated as the underlying invariant (no solid between the
player's head and the camera) so it survives Lane E swapping the house GLB.
