A LONG-SHORT, SINGLE-INSTRUMENT BTC trend model that deliberately copies the ONE structure this factory has ever promoted while CHANGING THE MECHANISM (exactly what L56 prescribes). This session proved the decisive fact: single-signal trend variants (VWAP, weekly MA, regression, breakout) all land at base Sharpe ≈0.6 with a CI on zero and die at the deflated-Sharpe gate — the risk-control engineering is irrelevant because the EDGE is too weak. The lone survivor reached Sharpe ≈2.0, and the difference is its structure: MULTI-TIMEFRAME CONFLUENCE (a fast signal must AGREE with a slow signal), FLAT ON DISAGREEMENT (sitting out the whipsaw regimes that drag single-signal Sharpe to 0.6), and TRAILING-STOP WINNERS. That agreement filter is the edge-booster. This hypothesis reproduces those three winning ingredients but with a DISTINCT signal type — a least-squares REGRESSION SLOPE rather than the survivor's momentum oscillator — computed on the 4H primary and confirmed by the 1D slope: it holds a side ONLY when the 4H and 1D slopes agree in sign, and goes FLAT when they disagree. It is single-instrument Binance USD-M pure-OHLCV (the only artifact-free, non-fragile substrate this session found — COIN-M times out, HL is history-capped, options infra is broken, multi-instrument produces non-physical return artifacts). NOT a rarity-gated breakout (the confluence is a sign-agreement that fires often, not an optimizable rare threshold → no few-trade corner), NOT always-in-through-drawdowns (flat-on-disagreement + trailing stop cap drawdown), NOT reversion/pairs/funding (dead). It changes the SIGNAL, not the ticker (L56). Exactly 3 tunable parameters: the regression lookback (scaled per timeframe), the chandelier ATR multiple, and the flat-band tolerance.
