Fix standing margin balance, restore the 20-name book, harden the panels
Executor - Size targets off (1 - CASH_BUFFER) x equity instead of 100%, and add a cash-restore pass over deadband-skipped overweights. A fully-invested target plus a one-sided min-trade deadband left the paper account on a permanent margin balance (-1,712 on 98.5k, gross 101.7%) that no rebalance corrected. - Place sells first and WAIT for terminal status before buys, so buys are funded by settled sells rather than briefly by margin. - Drop the no-op ticker .replace(".", "."). Book - Add MIN_POS_W (1%) floor alternating with the 15% cap. The 13F size column spans ~140x, so the tail rounded below the $493 min trade (BSX $26, PODD $14, DINO $71, VEEV $235) and four target names were never bought: a "20-stock" fund holding 16. Effective breadth 6 -> 10.4. - Extend SPY with live Alpaca bars for the regime test, so the fund's biggest switch no longer waits on a bundle that can be 9+ days stale. - Memoise compute_book for 15 min; the real rebalance forces a fresh book.
