D's live replay caught landmine 1: bench.js read def.wind.venturi off the STORM def where a venturi never lives (it is SITE data, main.js:453), and the probes never attempted it — every site_02 bench number was funnel-off, the third harness to make B's Sprint-11 mistake. Verifying the fix exposed landmine 2: the tools remapped anchors to a static sway:()=>pos, freezing the gum tree whose sway is the dynamic load a tr1 rig eats (ablation on the $80 line's q4: 1.02 funnel-off/static, 1.03 funnel-on/static, 1.24 funnel-on/real anchors). Backyard numbers matched D's UI to the decimal precisely because p1..p4 are posts — both landmines are no-ops there. Fix: windForSite(stormDef, siteDef, anchors) in weather.js is the one shared wind builder (venturi + shelters, exactly main.js's wiring); all garden_bench tools build wind through it, fly world.anchors themselves via a re-pointable wind proxy, print the venturi in their headers, and drop the phantom 12 s settle (commit->attach->storm is one keypress, and the settle skewed storm sampling via SailRig's internal clock). c.test.js pins the helper with B's strictly-raises assert against the real shipped funnel (mutation-checked). Corrected numbers: $80 line wildnight 91.9 with q4 at 1.24-vs-1.2 rating - a knife edge the real game falls off (D UI: q3+q4 break, 39.8 TATTERED; D's UI is canonical there, and a corner over its rating is not a safe line either way). Buster verdict stands (95.2 bench / 97.9 D live). Icenight 9 DEAD 2/4. Bench still under-reads UI peaks ~5-15% on site_02 - residual in the pool, stated in THREADS. Separation-target site_02 example withdrawn to A. Selftest 341/0/0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
