+- **★ RESEARCH (operator 2026-07-13): dvol quanta sweep × market regime** —
+  sweep the vol-gate threshold across its entire range; per quantum measure
+  trade result / ROI / DD / all metrics; then the same MODULO market regime
+  (MARAS-or-whatever fingerprinting — regime tagging itself "more or less
+  solved but not conclusively"). PREREQ (small, cheap, do before the sweep):
+  persist the per-trade dvol value AT ENTRY (not just gate pass/fail) — same
+  field the DDSketch self-tuning gate needs. Existing single data point:
+  EXP_VOL_GATE_RELAX 2026-07-04 (relaxed −17,847 / 189 trades vs normal
+  +3.54 avg / 7,883) + F5 relax window 2026-07-12/13 (4 ADVSL losers,
+  MFE ≤ +0.013%).
+- **★ RESEARCH (operator 2026-07-13): scan-cadence effects study (11.06s UV
+  vs 5.97s NG7-pinned BLUE)** — cadence effects on EVERYTHING: ROI, SL/TP
+  achieved gain/loss, opportunity cost. Includes the bar-denomination
+  question: are bar-constants (ADVSL min_hold=20, MAX_HOLD 100/125/250/375)
+  hold-TIME (wall-clock, convert via avg scan duration) or evidence-COUNT
+  (N OBF observations)? Empirical, decides whether to time-normalize or
+  cadence-match. Related: TP-overshoot mechanism — BLUE effective TP ~0.3
+  vs 0.20 configured: bar-cadence miss (beneficial upswing capture) vs
+  modulation×1.40; measure exit_pct − tp_effective_pct on BLUE TP exits.
+  UV at-tick TP_FLOOR (arm at .20 sharp, exit on give-back) is the operator's
+  current best expression; keep unless study finds better.
+- **★ RESEARCH (operator 2026-07-13): win/loss streak wave-phase alignment** —
+  treat win-loss/loss-win STREAKS as a wave (profit/loss as amplitude);
+  test PHASE match (in-phase / out-of-phase) against vel_div regimes,
+  quantized to the 11s/6s scan cadence. If found and stat-significant,
+  operator conviction: these waves are the unlock for the SHORT/LONG
+  regime-switch grail.
