The Aggregated ingest tier bucketed trades by hour incl. the current, still-growing
hour, then upserted via ON DUPLICATE KEY UPDATE (mutable rows). The PnL engine
checkpoints positions by row Id, so a bucket that keeps growing after being applied
had its later growth silently skipped (Id <= LastAppliedTradeId).
Extract the duplicated aggregation logic from PollingWorker + TradeHistoryWorker into
TradeAggregation.AggregateCompletedHours, which only aggregates COMPLETED hours; the
current hour is deferred (re-fetched next cycle) so every persisted aggregate is
immutable. +3 unit tests.

- D1/D2/D2c: Added TraderTraits entity, TraderTraitCalculator, Market Return Metrics (MedianWin, AvgWin, etc.), and trait filters
- D3: Implemented HF-Trader Tiering via IngestMode (Full, Aggregated, SnapshotOnly) and updated TradeHistoryWorker to respect tiers
- E1-E5: Added MasterStatus to Trader, TraderWindowMetrics for rolling analytics, Fingerprint metrics (PriceBandProfile, P50/P90), Copyability aggregates (Volume, Drift, Edge)
- E6: Implemented GET /api/traders/{id}/profile and GET /api/traders/correlation
- Replaced FIXPLAN-2026-07-09.md with FIXPLAN-TODO.md and FIXPLAN-DONE.md
- 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
in preparation for version control.
