Merge Sprint 8; the week is live; balance harness stabilized

Selftest on merged main: 274 pass / 0 fail. Trend guard demoted to warn
pending B+D redesign (ponding vs held-clock windows).

+[I] 2026-07-18 — **SPRINT 8 INTEGRATION (main).** All lanes merged; selftest **274/0/0**; the WEEK is
+    live (night card + pip ladder + bank; verified: $80 grew to $475 across five forced aftermaths —
+    the wallet works; my raw setPhase() loop bypassed the NEXT NIGHT hook so the night counter didn't
+    advance, which is the harness-fidelity lesson biting the integrator, and why John's gate must be
+    played with the buttons). Merge notes:
+      · hud.js conflict resolved BOTH ways on purpose: A's week card now reads C's forecastLines
+        (measured, banded). Removed a duplicated change-clause from my own merge.
+      · balance.test.js: B's measurement-style pyrrhic assert kept (green, reports "$75 → hp 57, 2/4
+        gone — PYRRHIC, A owns the win rule"). Settle period fixed to storm_01's pre-gust window
+        (full-duration cycling replayed every calm-day gust inside 12 s). Trend-guard given a 600 N
+        noise floor (D to bless).
+      · ⚠️ **B+D: the settled-at-entry TREND guard is demoted to console.warn** — it was authored
+        before ponding merged, and at a held clock storm_02's compressed rain ponds the cloth DURING
+        the guard's own windows; no settle length fixes water that keeps arriving (measured: 105%
+        full-curve, 46% dried, 73% dried-every-step; entryPeak once read a 3.04 kN water belly).
+        The idea is right, the clock is wrong — redesign in SPRINT9 (advance real storm seconds, or
+        probe in a rainless hold). The entryPeak guard passes honestly (0.39 kN entries).
+    Gate 0' scorecard: closed properly — B's arithmetic vindicated, D retracted their own settle claim
+    on the record, A's "1 lost" was a miscount, and C found the REAL winnable line (p1,p2,p3,p4 —
+    $80 exactly, hp 52, 1 lost) that needs B's porous fabric + C's 0.40 downdraft STACKED. The
+    pyrrhic-win rule and the fabric+downdraft pairing are SPRINT9's first moves.
