Phase-1 upgrade applied to the PoC base sleeve: rank residual momentum (each coin's
return stripped of its rolling beta to the equal-weight market) instead of raw momentum.
Removes high-beta coins dominating the sort by market co-movement. Backtest: gross
+0.82->+0.99, net @$20M +0.40->+0.57, capacity $5M +0.60->+0.78, CPCV-med +0.47->+0.59,
combined two-sleeve book +1.56->+1.66. Same edge, cleaner construction. Live panel depth
bumped to cover the 60d beta window. No lookahead (beta + cumsum use closed bars).

backtest now reports momentum + VRP (tail-managed, corr -0.04) + COMBINED book
(momentum 70% / VRP 30% risk) Sharpe +1.56, all years positive. paper marks BOTH
sleeves + combined equity each run; status shows all three + live Sharpes. VRP gate
('don't sell vol when DVOL rising/elevated') runs live -- currently 'flat (gated)'.
cwd-independence fixes: pit_sweep.load + _vrp_calib now use abs paths so the cron paper
run calibrates VRP correctly from $HOME (was silently falling back to zero-VRP). Live
panel depth bumped to cover the 60d VRP gate window. Honest: VRP +2.85 is the no-Greeks
proxy (real ~1-1.5) so combined is optimistic (~0.8-1.0 realistic) -- still > momentum alone.

- Rebalance keyed on FIXED calendar phase (epoch-day%7==0 -> Thursdays) instead of
drifting days[0]%K, so backtest and live agree on rebalance timing.
- STATE path absolute (relative to script) -> paper mode runs from any cwd (cron-safe).
- Backtest unchanged (net +0.40@$20M, CPCV-med +0.47).
Installed system crontab (daily 12:07): marks paper PnL daily, rebalances Thursdays,
logs to data/surfer/paper_runs.log. Forward-test seeded inception 2026-06-06.

One-file PoC of the validated crypto XS-momentum edge. ONE shared compute_weights()
drives backtest AND live (no skew); no lookahead; funding-as-PnL; sqrt-impact cost.
Backtest reproduces research (gross +0.83, net +0.43@$20M, capacity curve, turnover
9.8%). Regime diagnostic = clean NEGATIVE (no feature predicts momentum favorability,
IC~0 IS/OOS) -> de Prado meta-labeling/regime overlay empirically unwarranted, runs
flat-sized. Paper mode = live forward-test (Binance ASCII perps, market-neutral book,
intended trades + paper PnL persisted). Python is the right tool for weekly crypto MFT;
foxhunt Rust/CUDA is HFT-ES-specific (concepts reused, plumbing not).
