Fingerprint-snapshot foundation + strategy-drift calculator (#3/#5 groundwork)
TraderAnalytics is one row per trader, overwritten every recalculation, so there
is no history to detect strategy drift (#3) or edge fade (#5) against. Add the
missing time series:
- TraderFingerprintSnapshot entity (score, category concentration, conviction,
P50/P90 sizing, hold duration, trades/week, category-mix JSON, trait-set JSON)
+ migration AddFingerprintSnapshots (indexed by TraderId, CapturedAt).
- FingerprintSnapshotService (Infrastructure): CaptureDueAsync snapshots every
copy-relevant trader (CopytradingScore >= 40) at most ~once/day; wired into
ScoringAndAlertsWorker. GetDriftAsync reads latest-vs-baseline drift.
- FingerprintDriftCalculator (pure, Application): flags score drop, concentration
shift, sizing jump, conviction sign-flip, category-mix TVD, trait-set change.
- GET /api/traders/{id}/fingerprint-drift?baselineDays=14 read endpoint.
- Tests: drift calculator (4 scenarios) + capture service (copy-relevance,
throttle, drift read).
This is the shared foundation both #3 (drift alarm) and #5 (edge freshness) build on.

Rework insider feed: system-level InsiderWatch + dedicated view (no watchlist writes)
Watchlists will become per-user once the product is offered commercially, so the
system must not auto-add/remove traders there. Decouple insider tracking entirely:
- New system-owned entity InsiderWatch (TraderId unique, FirstDetectedAt,
LastAlertedTradeAt) + IInsiderWatchRepository; migration AddInsiderWatch.
- AlertService.EvaluateInsiderWatchAsync now maintains InsiderWatch (not the
watchlist): registers each possible_insider wallet, seeds the high-water mark
at detection time, and fires one InsiderActivity alert per new trade. Dedup via
LastAlertedTradeAt.
- Dedicated "Insider" view: GET /api/traders/insiders + InsiderDto + a new
Insider-Radar page (sorted by market-surprise). Read-only, separate from watchlist.
- Revert the WatchlistEntry.LastInsiderAlertAt field + its migration (unapplied);
drop the now-unused IWatchlistRepository.UpdateAsync.
- Tests updated to assert InsiderWatch registry (and that no WatchlistEntry is created).

- Cleaned up API docs and plan to use generic terms (removed hardcoded PolyTrader references)
- Added respective EF Core Migrations
Clean Architecture .NET 8 solution (Domain/Application/Infrastructure/Api/Worker/WinFormsHost)
for analyzing Polymarket traders for copytrading/strategy-replication candidates.
Includes EF Core InitialBaseline migration and DB secrets removed from source/config
