v0.2.2 — External contribution and duplicate diagnostics
Backtest Integrity Guard v0.2.2 ships the project’s first merged external contribution.
Highlights:
- distinguish exact duplicate bars from same-timestamp OHLC(V) conflicts
- new DUPLICATE_BAR_ROW and TIMESTAMP_CONFLICT findings
- preserves DUPLICATE_TIMESTAMP for compatibility
- duplicate comparisons respect configured field mappings
- zero-setup Google Colab quickstart
- 16 tests passing on Python 3.10, 3.11, and 3.12
Contributor credit:
- Thanks to @vansh-nagar for implementing the duplicate/conflict diagnostics in PR #16.
The release remains dependency-free and contains no trading strategy logic or proprietary market data.
