Previously, bootstrap_trace_data would capture execution traces in the `prediction` parameter of wrapped_metric, but then discarded them. Metrics would always receive trace=None instead of the actual trace. This would break metrics that use the trace. Also fixed attempted division of two lists, dividing their lengths instead.

Ping - could somebody please take a look? |
When raise_on_error=False and unpacking fails, the previous code used `continue` which skipped adding the failed example to the output list. This broke the 1:1 correspondence between inputs and outputs, causing issues in GEPA which zips outputs with validation IDs. The fix adds a placeholder entry with an empty trace, allowing downstream code (like make_reflective_dataset) to skip it gracefully while maintaining correct output ordering. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
