"""Precompute the $1,000 paper portfolio server-side, off the cache.

The dashboard's top page used to replay the followed wallets' trades client-side,
which (a) hammered the data-api/clob from the browser and (b) phantom-locked capital
because the data-api misses resolution dates for high-volume wallets. This computes
the same book here instead, sourced from cache.duckdb — which already stores each
resolved bet's entry price, size, win/loss AND resolution time (res_t), so capital
RECYCLES correctly (cash frees at the true resolution moment). Output -> portfolio.json,
which the dashboard reads in one request.

Model: a $1,000 account that mirrors each followed wallet's CONVICTION bets (top-20%
stake). Exits MIRROR the signal, like the live bot (2026-07-07): when the wallet
fully closed a position pre-resolution, the replay sells there too — close time from
/closed-positions, exit price reconstructed as avgPrice + realizedPnl/totalBought,
exit taker fee + slippage haircut paid, status SOLD. Bets they held to resolution
settle at the chain-truth payout (1/0/0.5 — refunds are scratches, not losses).
Complete in-window round trips on still-unresolved markets are replayed as
entry+exit (the old hold-to-resolution model missed them entirely). Sizing is
DYNAMIC — each bet stakes PCT of
current equity (Kelly-style compounding), halved in a >20% drawdown, capped at
EVENT_CAP concurrent bets per real-world event — and entries pay the Polymarket taker
fee plus a lag-slippage price haircut (FEE_RATE / SLIP / LAG_EST_S), so the book
models what a real copier nets, not the idealized zero-cost mirror. One position per
market (first wallet to enter wins the slot); when capital is fully deployed a bet is
MISSED.
Resolved history + realized P&L come from the cache; currently-open bets come from a
small live /positions pull so the page can still show what's in flight.
