A LONG-SHORT, SINGLE-INSTRUMENT BTC trend model that builds on the ONLY structure this factory has ever promoted and identifies WHY it worked. This session established, with data, that single-signal BTC trend has base Sharpe ≈0.6 (dies DSR) while the survivor reached ≈2.0 — and the difference is SELECTIVITY: multi-timeframe CONFLUENCE with FLAT-ON-DISAGREEMENT concentrates exposure into high-quality aligned-trend regimes and sits out the chop that drags single-signal Sharpe to 0.6. This hypothesis pushes that proven edge-source one step further — from the survivor's TWO screens (4H + 1D) to THREE (a 1W regime filter + 1D trend + 4H trend), requiring ALL THREE to agree before taking a side, and staying FLAT otherwise — a recognized 'triple-screen' construction that is more selective than the two-screen survivor and mechanically distinct from it. The weekly screen is used ONLY as a directional filter (not for sizing), avoiding the artifact/drawdown problems that killed standalone weekly sleeves. 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 returns). The 3-timeframe sign-agreement fires often enough in trends to avoid the few-trade DSR corner that killed the gated breakouts, and flat-on-disagreement + a chandelier trailing stop cap the drawdown that hard-abandoned the always-in sleeves. It changes the mechanism (three screens, weekly regime), not the ticker (L56). Exactly 3 tunable parameters: the shared trend lookback (scaled per timeframe), the chandelier ATR multiple, and the trend-slope flat-band tolerance.
