Win rate alone hides the payoff profile: an arb grinder (95% wins at +2%)
and a longshot holder (25% wins at +400%) need entirely different copy
strategies. D2c adds median+avg return of won AND lost closed markets,
profit factor, UI cards, and two derived traits (thin_margin_wins,
high_payoff_wins). Median leads (outlier-robust), the loss side is
mandatory — high win rates with rare total losses (resolution farming)
are exactly what the win rate alone obscures.

- Trait filtering is now a binding requirement: trait query parameter on
GET /api/traders (EXISTS-based), GET /api/traits with counts, dropdown
plus clickable chips in the UI.
- New trait possible_insider (D2b): detection via market-surprise
likelihood under market prices (won longshots count, won favorites do
not), with base filters (rare, large stakes, resolution farmers
excluded) and a v2 roadmap (buys-before-news timing, one-shot wallets,
topic concentration, urgency/slippage, niche markets).

- MarketCategoryMapper: classify from question text (the Gamma /markets
endpoint delivers neither category nor event tags, so on-demand markets
had no signal at all), match short tokens on word boundaries ("eth" no
longer hits inside "whether", "pop" not inside "popular"), widen the
keyword lists across all categories.
- UpdateMarketFields: never overwrite a tag-derived category with an
uninformative "Other" from the on-demand path.
- PositionPnLEngine: sync Trader.TotalTrades to the actual replayed row
count — the worker-side increment counters drift (INSERT IGNORE,
deletions, historic imports) and produced Trades30d > TotalTrades.
- Tests: 14 new (mapper classification + word-boundary regression,
TotalTrades sync + Trades30d invariant, category update guard via
SQLite) — suite now 32 green + 1 skip.
- FIXPLAN Teil D for the larger rebuilds (AggregatedCount column,
TraderTraits heuristics, IngestMode tiering for ultra-HF traders).
