#!/usr/bin/env python3
"""Run the adaptive multi-strat book on IBKR PAPER trading (realistic fills, no capital).

Gets target weights from the harness (Yahoo data), connects to your IB Gateway/TWS paper account,
and rebalances the ETF book on it. Crypto sleeve -> IBIT (Bitcoin ETF: in-brokerage, no crypto-
exchange counterparty tail). Default DRY-RUN (shows intended orders); pass `rebalance` to place them.

SETUP (you do this — your credentials, never me):
  1. Create a free IBKR paper-trading account (or use your live account's paper login).
  2. Run IB Gateway (or TWS) and log in to the PAPER account.
  3. In Gateway/TWS: API settings -> enable "ActiveX and Socket Clients", note the port
     (IB Gateway paper = 4002, TWS paper = 7497). Add 127.0.0.1 to trusted IPs.
  4. Then: python3 scripts/surfer/ibkr_paper_book.py status        (test the connection)
           python3 scripts/surfer/ibkr_paper_book.py dry           (show intended orders)
           python3 scripts/surfer/ibkr_paper_book.py rebalance     (place orders on PAPER)
  Override port: ... <mode> --port 7497

Sizing uses Yahoo last-close (consistent with the book); IBKR fills at market. Hysteresis: only
trade a name if its target $ drifts > 3% of NLV. Run weekly/monthly via cron once validated.
