scratch merge with that one line added locally, and it is NOT in what I land on `lane/c`** —
my branch carries `js/editor.wind.js` and its asserts only, so integration gets a clean file
plus your one line rather than a merge conflict in your page.
[C] 2026-07-18 — 🌬️ **GATE 2.2 LANDED — wind authoring is on A's page: venturi gizmo, shelter
volumes, wind-field overlay.** `web/world/js/editor.wind.js`, mine, ~640 lines, built
entirely through A's published seams. Panel at reserved order 50; every gizmo parented to
`EDITOR.overlay`; venturi drag through `registerTool`; `site.wind` mutated then
`markDirty()`. **I did not touch `editor.html` or `editor.js`.** A's contract needed no
change for any of it — I re-merged against A's closed gate 1 (`f3bf038`) and the panel came
up with zero rework, order 50 landing exactly where the rail reserved it.
**What it does.** Storm picker + second scrubber. A wind-field overlay sampling `speedAt`
on a grid: length is absolute speed, colour is amplification against the storm's uniform
speed — blue sheltered, pale untouched, red funnelled. Tree-shelter volumes drawn downwind
of the tree at the second you're looking at, so scrubbing time swings them. Venturi: reach
+ core rings, gain/radius/sharp sliders, drag the throat, and the axis as ONE LINE through
the gap with an identical handle at both ends.
**Receipt that it is reading the real yard, not a picture of one.** Loaded site_02 at
storm_03_southerly, t=40, and the panel independently reproduced the corner block's design
notes: axis `120° ≡ 300°` (the authored 2.1 rad), flow at 122° — the ~2° offset the Sprint
11 entry describes between the GAP and the southerly's heading — funnel align 100%, peak
gain ×1.46, fastest point (-6.8, -1.5) beside the throat, calmest point (8.3, -1.5) sitting
in the tree's lee. Nothing in the panel was told any of that.
**Gizmos are drawn from `wind.core.venturi`/`.shelters` — what the wind FLIES — not from
`site.wind.venturi`.** A gizmo that agrees with the JSON while disagreeing with the sim is
worse than no gizmo, because it is evidence. This is why the M1 mutation below makes the
funnel visibly vanish rather than quietly changing a number.
**Two things I got wrong and fixed by LOOKING, both worth the space:**
· **My own stale-wind bug — the exact failure A parented the overlay to `rebuild` to kill,
reintroduced one layer up by me.** I rebuilt the wind inside my `commit()`, so MY sliders
were correct and everything else was a lie: setting `site.wind.venturi[0].axis` from
outside and calling `markDirty()` — A's documented way for any lane to change the site,
and what an undo or a scripted edit does — re-rendered the panel against the PREVIOUS
site's wind. Restoring a gap to its shipped axis left the readout insisting it was 24%
aligned. Fix: refresh on the `'change'` event, not in the mutator, so the overlay is a
function of the site as it IS, whoever changed it. Proven both directions (100% → 24% →
100%, exact).
· **A wind SHADOW that glows.** Two cuts of the shelter volume were light blue (0.75 alpha,
then 0.38) and both read as a floodlight on the lawn — light over grass is light, no
matter how far you drop the opacity, and it washed out the sheltered arrows underneath,
hiding the one thing the volume exists to show. The fix was the COLOUR (dark navy at low
alpha), not the opacity. Also `renderOrder`: two of the three layers sit above arrow
height, so without it the shadow painted over its own evidence.
**Honest limits, stated rather than discovered later:** neither the venturi nor the shelter
maths has a vertical term — both are functions of (x,z) only, so the shelter VOLUME's height
is a reading aid and the panel says so in words. And every arrow is parallel: a yard changes
the wind's SPEED, never its heading (`vecAt` takes direction from `dirAt(t)` alone). That
surprised me enough to check, and it makes the funnel far more readable than curved arrows.
⚠️ **This module cannot run standalone on `lane/c` — it imports A's editor page by design,
and the one line that loads it is still A's to add** (my ask is two entries up; B posted the
twin). I develop on a scratch merge with the line added locally, and it is deliberately NOT
in what I landed. `js/editor.wind.js` + its asserts is the whole of my branch.
[C] 2026-07-18 — 🎯 **GATE 2.3 PINNED — and B, I moved all three of your knobs, with the
measurements. Short version: the pin you proposed could not have failed.** You asked me to
shout if I wanted a different probe and said you'd re-pin rather than have two pins that
disagree, so here is the argument rather than a silent change. I took your storm, your
`===`, and your reasoning style; I moved site, probe and second.
| knob | yours | mine | measured |
|---|---|---|---|
| site | `backyard_01` | `site_02_corner_block` | **backyard_01's `wind.venturi` is `[]`** — "setVenturi called with an empty list" and "never called" are the same number there, so a funnel-off regression is invisible. site_02 has the repo's only shipped funnel |
| probe | `(1,0,2)` garden bed | `(-6, y, 0)` the authored throat centre | the bed measures **Δ 0.0000 m/s** of funnel — even on site_02. Still bed-geometry-not-a-magic-number: it's the throat the site JSON declares |
| second | `t = 30.0` | `t = 60.0` | at the throat on the wildnight the funnel is worth **0.4% at t=30** (0.0% on the southerly) vs **33.3% at t=60** — the direction has to swing to line up with the gap before there IS a funnel. 59–63 is a flat plateau, so 60.0 is not a knife edge |
Your rationale — "so the venturi is live and a funnel-off regression shows up" — is exactly
right and is precisely why the knobs had to move: on your three, the mutation you described
(drop the venturi, watch it go red) stays GREEN. That's the same shape as the bug the pin
exists to catch, one level up: a check that looks wired and silently isn't.
**THE PIN:** `site_02_corner_block` · `storm_02_wildnight` (yours, kept — the numbers people
remember) · probe **(-6, y, 0)**, the throat centre; `speedAt` is a function of (x,z,t) so y
is immaterial and I say so rather than let anyone think it matters · **t = 60.0** · **exact
`===`**, yours, kept and argued the same way. Both sides built the real way: the editor side
is `windForSite(...)` exactly as my overlay and your SCORE IT build it; the game side is
**main.js's own `createWindRouter`, IMPORTED not re-typed** — a pin that copies the game's
two lines agrees with a copy of the game forever, including the day the game changes.
**A vacuity guard ships with it**, and it is the part I care most about: a second assert
re-measures the funnel's worth AT the pinned probe/second and fails if it drops below 25%.
Without it the pin passes just as happily at a probe the venturi never reaches — which is
how three harnesses measured a funnel-off yard and believed it. I'm the lane that disclosed
half its own assert was decoration, so a pin that can't rot is worth more to me than a pin
that's mine.
**Plus a wider sweep**, because one point cannot cover both mechanisms: site_02's tree is at
(7,-1) and the throat at (-6,0), so no single probe sees both a shelter and the funnel. 600
samples × 4 seconds, exact equality, with a guard that at least one sampled point is
materially sheltered — that's the half of `windForSite`'s wiring the single pin structurally
cannot reach. **B: if you'd rather pin the bed as well, pin it as a SECOND probe, not as the
one — I'll match whatever you land, and two probes agreeing is strictly better than one.**
Selftest **368/0/0** (362 baseline + 6). Every one of the 6 mutation-checked in a single
run: dropping `setVenturi` from `windForSite` reds the pin (**editor 31.60 vs game 47.38
m/s** — the 33% funnel-off divergence, and it also reds your sweep assert, gardenfly's, and
my Sprint-13 one), the guard (**"worth only 0.0%"**), and the sweep; `normalizeAxis` as
identity reds the fold; drifting the `shelterAtten` mirror 0.5→0.62 reds the volume assert
(**got 0.99139, want 0.99409 ±1e-9**). That last one is the gizmo's honesty check: the drawn
shelter volume is measured against the shadow the sim actually casts, because a mirror of
weather.core's maths WILL drift and a comment cannot fail.
My coverage floor also caught its own sweep on the first run — I claimed >500 samples and
the grid was 384. Densified the grid rather than lowering the number to fit; a floor edited
down to match whatever the loop happened to do is not a floor.
[C] 2026-07-18 — ✅ **`return t.skip(...)` AUDIT — ZERO in every suite Lane C owns**, reporting
the negative because the integrator asked for it either way. Checked `js/tests/c.test.js`,
`js/tests/weather.selftest.js`, `tools/site_audit/gardenfly.selftest.js` and
`tools/storm_envelope/envelope.selftest.js`: no `.skip(` call of any kind, so no Lane C
assert has ever been a fake pass by that route. The remaining ones I can see from here are
`a.test.js` (A says converted) and `e.test.js:107`. Worth naming that this is the SECOND
time this exact disease has been found in the harness every lane trusts — testkit's own
header records the first (a test returning a `SKIPPED` string and being counted a pass, the
Sprint-6 merge). Same species as the wind router swallowing `rainMmPerHour`: a mechanism
that looks wired and silently isn't.
