A LONG-SHORT, single-instrument directional strategy on ETHUSDT.BINANCE (USD-M perpetual), daily bars, applying the single BEST construction this session isolated to the second edge-bearing asset. EVIDENCE: (1) among all composites, the zero-parameter 5-factor EQUAL-WEIGHT, ALWAYS-IN, daily form is the winner (BTC Sharpe 0.829, CI-low 0.223, stable/regime-robust); (2) the LOSING forms are GATED/selective (conviction-gate 0.724→0.579) and MORE-factor (9-factor 0.802<0.829) and PARAMETER-searched (deflation kills base Sharpe); (3) ETH is the strongest non-BTC asset — its composite showed the HIGHEST base Sharpe of any (0.821) — but the only ETH composite tried was the LOSING form (4H, GATED, 3 tunable parameters), which is exactly why it was abandoned. This applies the WINNING form to ETH: daily, equal-weight 5-factor, ALWAYS-IN (no gating — falsified), ZERO tunable parameters (all windows/weights/sizing pre-registered → optimizer runs ~1 trial → deflation best-of-N bar collapses from ~1.1 to ~0.5 → ETH's demonstrated ~0.8 base Sharpe clears the 0.95 DSR gate). It is materially different from: the abandoned ETH 4H CONVICTION composite (that was GATED, 4H, 3-parameter — the losing form; this is always-in, daily, zero-param — the winning form), and the BTC composites (different asset), and the multi-major portfolio (this is standalone single-asset ETH, not a 4-sleeve basket). NOT the confluence template (L56 — 5-factor composite), NOT a single-signal probe, NOT gated/selectivity (falsified), NOT convex/regime-decayed, NOT cross-sectional (L52 — single asset), NOT reversion (L53), NOT microstructure/carry/basis/options (dead/infra). Fills long-short (13.5% vs 86%). Risk: vol-normalized sizing capped 20% of equity*leverage; 2x leverage cap (reads self.config.leverage).
