(1) IBKR paper reports summary fields (cash/GrossPositionValue) inconsistent with actual positions
(found: $141k/13% gap, fills+positions are ground truth). Bot now cross-checks NLV vs cash+position-
market-value, WARNs on >2% gap, sizes on the CONSERVATIVE NLV (never inflates), and a gate refuses to
trade if the gap exceeds MULTISTRAT_DATA_TOL (default 25%).
(2) build() included today's INCOMPLETE intraday bar when run mid-session -> spiked vol estimate ->
halved the leverage (1.0->0.5) -> would have sold half the book as churn at the 14:35 cron. Now drops
today's partial bar; uses completed closes only (matches the daily-close backtest). Verified live:
leverage back to 1.0, book recognized on-target (in_band), no spurious orders.

Eyes-on EXECUTE=true validation caught two bugs: (1) fractional qty -> all 6 orders cancelled (10243);
round to whole shares (skip if 0). (2) last_rebalance was set even when all orders were rejected,
which would block retry; now only marked when >=1 order is accepted.
