Calibration & Regression Testing

[biosynthart]

• Compare DerivedParams output against audit table
• Run full test suite (12 existing + new trait/nutrient tests)
• 2000-tick regression: population curves, state transitions, event counts within ±10–15% of baseline
• Backward compatibility: worlds without species_definitions key fall back to legacy code paths

Update: Test suite now at 163 tests passing (up from 94). Two-pool nutrient flow tests added (test_nutrients.py). All existing tests pass with the trait-based engine.

Remaining work:

• Compare DerivedParams output against audit table (manual verification)
• 2000-tick regression: population curves, state transitions, event counts within ±10–15% of baseline

⏸️ Shelved — deferred until after the distributed engine scalability work is complete. Revisit once spatial hash + octree voxels are in place.
