C measured my proposed pin and it could not have failed. Converging rather than
landing a second pin that disagrees. Knobs are now C's:
site_02_corner_block / storm_02_wildnight / throat (-6,y,0) / t=60.0 / exact ===
Three wrong answers before this, all the same failure:
1. backyard_01 has venturi: [] — nothing to detect. (I found this one.)
2. site_02's BED is funnel-blind, Δ 0.0000 m/s. (Both of us, independently.)
3. t=30 on the wildnight is worth 0.44%. I MISSED THIS ONE: my throat
measurement read a healthy Δ +4.948 m/s and I trusted it, but that was on
storm_03b_earlybuster, not the wildnight the pin flies. A sensitivity
measured on one storm says nothing about another. The mutation check I was
proud of would have passed on the wrong storm.
Adopted C's vacuity guard and its 25% threshold — one number, not two. It is
the check that would have caught my proposal on its own: mutation asks 'did it
move', the guard asks 'is the funnel worth enough here that a wiring bug could
not hide in the rounding'.
Game side now imports main.js's createWindRouter instead of retyping its two
wiring lines (C's correction). My old version built BOTH sides with
windForSite, so it could only have caught a bad input, never a router that
routed wrong.
CONVERGENCE RECEIPT — my chain reads C's numbers to the decimal:
t=60 throat editor 47.38 game 47.38 exact === true funnel-off 31.60 = 33.3%
t=30 throat on 18.55 off 18.46 = 0.44% (C's finding, reproduced)
What my half adds over C's: C pins windForSite (the builder) against the game;
this pins buildScoringWorld — the path SCORE IT actually runs — against the
same router. Three chains, one number.
Kept the garden bed as a SECOND probe on C's explicit offer: what the sail
shades is what the audit is about, and equality there is a real claim even
though the funnel is not what decides it. Labelled as carrying no funnel
tripwire, because it cannot.
Mutation-checked: setting t back to 30 reds the guard and both tripwires with
the exact diagnostic (0.44%, 18.46 -> 18.55) while the EQUALITY asserts stay
green — which is precisely C's argument, reproduced on my own chain.
Selftest 375 passed / 0 failed / 0 skipped.
