## Changelog

### 2026-09-16

*Fixes*

- Preserves distinct Polymarket activity and trade legs that share a transaction hash, preventing valid fills from being dropped while still removing exact duplicates.

### 2026-07-14

*Features*

- Initial release with multi-wallet exports for open and closed positions, trades, on-chain activity, and aggregate portfolio value.
- Added market, date, side, activity-type, and position-size filters with bounded pagination.
- Normalized wallet, market, asset, PnL, trader profile, timestamp, and transaction identifiers into analysis-ready dataset rows.

*Reliability*

- Added retry backoff, conservative concurrency, duplicate prevention, and per-wallet error isolation for scheduled workflows.
