BTC top-trader L/S HIGH: val fade t=−2.17 but corr vs global 0.99; incremental γ t=−1.45. Same costume. NO_EDGE.

ETH/BTC |z|≥2 residual MR: discovery continuation (t=+2.18); val non-overlap fade LS t=+1.55 n=9. NO_EDGE.
BTC 5d extreme MR: discovery already continuation (t=+3.19); val fade LS t=−0.76 with n=4 extremes. NO_EDGE.
BTC 96-bar range extremes fail both fade and breakout on validation. They are 99.5% collinear with 24h trend. NO_EDGE.
Preregistered test: a causal Hawkes intensity gate on the BTCUSDT 1h vol-regime flagship cuts 21.7% of trades and 22.0% of gross edge. Net −49% at 4.404 bps/side. Rejected; WFA/MC not run.
BTC 1h 3-channel analog (close+vol residual+L/S) val mean +9.4 bp, t vs unmatched 0.42, t vs price-only 0.55. Wrong sign. NO_EDGE.
SOL 15m volume residual: raw C/A t=+3.48, residual t_γ=+1.08 fails val. Selection, not portable. NO_EDGE.
BTC funding fade: val gate fails (t H-M=-0.57); discovery LOW t~2.08 did not hold; OOS has 0 HIGH events under frozen P90. NO_EDGE.
