"""Polymarket insider-pattern detector.

Replicates the per-wallet methodology behind the Bubblemaps / 60 Minutes work:
flag wallets whose results are too good to be luck and whose behavior fits the
insider fingerprint. All signals come from Polymarket's public data API.

Signals per wallet (over resolved bets in a recent window):
  1. IMPROBABILITY  — wins vs the wins their entry odds imply. Each bet entered
     at price p has expected win prob p; observed wins far above Σp is the
     "luck alone can't explain this" z-score (and one-sided p-value).
  2. PRE-RESOLUTION TIMING — how long before a market resolved they entered.
     Entering minutes/hours before resolution is the classic advance-knowledge
     tell. We report median lead time and the share of wins entered <24h out.
  3. FRESH WALLET — account age (first observed trade). New account + big
     improbable wins is a strong flag.
  4. SIZING — average / max bet size.

Composite suspicion 0-10. Funding-cluster linking (the Bubblemaps "who funded
whom" step) needs a Polygonscan/Alchemy key — see cluster_stub().
