Independently corroborates A's p4 finding: downdraft is the weakest lever

hail-porosity question with the physics and three honest alternatives. Hands A
the week's variants and forecast uncertainty.

Measured against A's gate-1 winning line (t2+p3+p4+t2b, 4x shackle + spare,
tension 1.0, one repair) under an identical harness: the first draft's 26 s
hold gave 32 hail-seconds and landed ~39 HP below storm_02. That is not a
harder night — no amount of play recovers 39 HP when you are already flying the
best rig the shop sells. Hold 26 -> 12 s puts it at 21.1 hail-seconds (1.6x
storm_02, was 2.8x) and 13 HP below it, which excellent rigging + the repair +
the broom can answer — and night 5 arrives with four nights of banked money,
which is the campaign's own answer to escalation.
Week now: gust 11.3 / 21.4 / 21.2 / 32.3 / 28.3, hail-seconds 0 / 2.4 / 2.4 /
11.4 / 21.1. Force ramps then plateaus while the question changes underneath.

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.
Selftest 241/0/0.

The wild night's blocker is geometry, not drain weights: the best
bed-covering quad puts 7.4 kN on p1, above the 6.5 kN rated shackle, so
no loadout at any price holds it. Re-orders the lever list toward load.
Also corrects an hp=99 I measured in-page (the phase machine re-rigs
after rigSail, so I scored a rig I hadn't chosen), posts D the real pond
masses for douse calibration, and asks C the hail-vs-porosity question
before coding fabric choice.

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).

Tells B and C to re-measure before spending the drain-weight and downdraft
levers — stacking them blind makes attribution impossible. Includes the p4
position sweep and the "do not pull it closer" boundary, since a.test.js's
>45 m2 floor is the tradeoff's only guard.

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.

Freezes the pond API for D (broom) and A (HUD), resolves D's tn-1.04
cliff as real ponding load rather than solver instability, and flags that
flat rigs die to wind before water on the current yard — so ponding is a
twist-tax today unless the yard gets a non-collinear level anchor trio.

pondMass/pondCentroid/drainPondAt/dumpPond threw when this.water didn't
exist yet — Lane A's HUD reads pondMass() every frame, including in the
forecast/prep phases before the sail is rigged. Node tests always attach
first so they never hit it; the live game did on the first frame. Guarded
+ a pre-attach assert so it can't regress. Verified in the assembled game:
a flat quad ponds 780 kg (belly sagging below ground), dumps on break,
and the merged browser selftest is 219/0/0.

The water arc, carried since Sprint 3. Rain (Lane C's rainMmPerHour x the
exported RAIN_TIME_COMPRESSION, never hardcoded) lands on each node's
horizontal projection, runs down its steepest of 8 neighbours, and pools
where it can't get out. A flat sail's belly is a basin water flows into
and can't climb from; a hypar drains along its saddle ridge to the low
corners and off — so ponding cannot pincer §7, and measured on real yard
quads a flat rig holds 12 kg/m² vs a twisted rig's 1.7.
The 8-neighbour graph is load-bearing: a 4-way one can't follow the
saddle's diagonal ridge, so it trapped water in the gravity belly and a
hypar pooled as much as a flat sail. Steepest-GRADIENT descent (not
steepest drop) because a diagonal is √2 farther.
Gate 1, in asserts: a flat carport rig under a capped wind survives dry
(4/4) and dies wet (a corner at t=85s) — the control isolates water from
wind — and the broom saves it. Plus dump-on-break, dump-on-tension-up
(the turnbuckle counter-play), mass conservation, and a belly-tear safety
valve at 4 m of sag.
API for D and A, frozen in contracts.js: pondMass(), pondCentroid(),
drainPondAt(node, dt) -> kg-on-your-head. session.reset() for A's "play
again".
On D's tn-1.04 cliff: investigating it IS what surfaced the ponding load
regime. The 10 kN "spike" is real physics, not solver divergence — a
155 m² flat sail holding 2100 kg of water genuinely pulls ~21 kN, stays
finite, and tracks the water. So no physics-altering clamp (the
displacement clamp I tried moved the thesis 39->34%); instead an opt-in
`watchDivergence` tripwire that throws with a repro above 80 kN, live in
every selftest rig and never false-tripping, and a belly-tear that bounds
the runaway physically. Full writeup for D in THREADS.

A's router tripwire ('wind router forwards EVERYTHING the real wind exposes')
went red the moment weather.js grew hailAt/hailSize — which is the tripwire doing
exactly its job. A's own comment on createWindRouter is the standing instruction:
"Anything new on the wind contract must be added here too." Without this, the
garden score (which hangs entirely off gardenHailExposure → hailAt) would be
inert in the game while every assert passed — the precise silent-swallow this
tripwire exists to prevent, and the second time it would have bitten hail.
Two forwards, matching the existing pattern. Selftest 216/0/0, tripwire green,
and hail now reaches skyfx in-game with no console patch (verified). Flagged to A
in THREADS since it's their file.

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.
Selftest 209/0/0, 36 output files byte-identical across two runs.

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 tripwire is aimed at Lane C's incoming hailAt(): the router swallowed C's
rain API silently once already, and decision 13 hangs the whole garden score off
hail, so the same omission would recreate the exact problem Sprint 5 exists to
fix. Also records that Sprint 4's headline finding was re-measured against a true
control and survived.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.

The broom is this sprint's gate and B's spec says the two lanes meet in the
middle. Posting the shape now rather than at the end so B can land it while I
build against it: ponds[] with a live world pos (I have to walk under the
belly), and drainPondAt returning the kg dumped (that number decides splash vs
stagger vs flat on your back).

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.

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.

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.
