[Research] Validate recovery methods on real VENUS experimental data

[KedoKudo]

Parent Epic

Part of #172 (2D Resonance Imaging)

Description

Final validation of recovery methods using real experimental data from VENUS.

Approach

Since ground truth is unknown for real data:

1. Use independent measurements for validation
2. Compare to bulk sample analysis
3. Check physical consistency (abundances sum to 100%)
4. Cross-validate with different methods

Validation Criteria

• Physical consistency: Abundances in valid range
• Spatial coherence: Results make physical sense
• Method agreement: Different methods give similar results
• Uncertainty: Reported uncertainties are reasonable

Test Data

Real experimental data with severe sparsity from VENUS instrument.

Tasks

• Select appropriate test datasets
• Apply each implemented recovery method
• Compare results across methods
• Assess physical consistency
• Document findings and recommendations
• Create validation report

Dependencies

• Requires: At least one recovery method implemented
• Requires: Synthetic validation complete
