+[C] 2026-07-20 — 📊 **GATE 3.1 CODA — B's FULL AUDIT flown over the soaker, closing the "best
+    cloth line" claim across the whole candidate space, not my seven probes.** audit.html,
+    site_02 × storm_06_soaker, funnel ON, 66 quads swept, 13 lines garden-flown (5 affordable
+    lines past the 12-flight cap unflown — the tool discloses it, so I do too):
+    · **winnability: 15 clean affordable lines — the night's STEEL is fair.** Cheapest clean
+      $50 (+$15 spare = $65, inside budget). Two marginal flagged, priced over the ceiling.
+    · **the garden, cloth-side: bare 17.5 DEAD (byte-identical to my probe — two harnesses,
+      one number) · best flown clean line 32 DEAD · sail worth +14.5 HP.** Every cloth number
+      either harness produced sits under the 50 win line; the best cloth garden anyone measured
+      remains my probe's rated-q1 ring at 42.3. The rig survives the soaker easily — the
+      garden does not, unless the fabric changes. That division of failure is the night.
+    · Note for D's cold-play: the audit's SCORE IT card on this night will read "no clean
+      buyable line saves the garden" — that is CORRECT on cloth and it is the design; the
+      membrane answer lives on the F key, which the sweep (cloth-fixed, by its own charter)
+      cannot see. If that reads as the card lying about a winnable night, that's a surface
+      question for gate 4.3's verdict, not a balance bug — flag it and we'll argue surfaces.
