"""Pin the live paper bot's per-wallet conviction floors to the backtest's.

PARITY FIX (2026-07-07): the bot used to derive floors AT BOOT from the
data-api's most recent ~500 positions (copybot.derive_floor). The backtest
(portfolio.py) uses the TRUSTED cache p80 over ~180 days. When a wallet's
recent bets ran bigger than its long-term norm the two diverged hard —
fortuneking's boot floor hit $1,498 vs the backtest's $892, so the live bot
silently filtered out conviction bets the backtest counted (and the floor
drifted every restart). This writes the backtest's floor as a PINNED
`floor` on every wallet in copybot.paper.json, so both books gate on the
same threshold and boots are deterministic.

Uses the exact backtest method: trusted_wallet_rows (trust.py) deduped to
one row per market (largest stake), then cache.conv_cutoff (p80). Wired into
daily.sh after portfolio.py (cache warm, floors match that run); the publish
step commits copybot.paper.json so the next bot restart picks them up.

    python3 sync_floors.py        # writes live/copybot.paper.json floors
