Scope: This audit is performed on the current Submission_Package only, using evidence from the following locations:

1. Core Data Integrity

According to data_quality_check.py and its output data_quality_report.txt, the following CSV files were checked:

Conclusion: All core CSV files mentioned in the paper are complete (no missing values, no duplicated rows), consistent with the textual claims in data_issues_and_suggestions.md and final_data_validation_report.md.

2. 3σ Outlier Analysis and Range Characteristics

Using data_quality_report.txt together with the newly executed analyze_outliers_and_params.py, 3σ outliers were re-counted and exported for inspection:

Conclusion: The statement “38 3σ outliers in C_ell_TT and 11 in k” is exactly confirmed by the automated checks; the newly exported CSVs and plots provide concrete ℓ/k ranges for physical interpretation and for inclusion in figures.

3. 7.91σ Result & Reproducibility

3.1 Consistency Between Script and Formal Reports

No script or result file in the submission package supports claims like “maximum Z≈13.6σ” or “60–90% high-Z events”. All Z-related prose has therefore been aligned to the 7.9σ / 4% figures, which are robustly documented in the formal materials.

3.2 Audit Conclusion

4. CL/PK Baseline Comparison & Systematic Bias

4.1 CMB Cℓ (CL) Residuals

Conclusion: The claim that “toy_cl_bestfit shows ~80% relative residuals against baseline_cl, indicating a systematic bias” is quantitatively supported.

4.2 Matter Power Spectrum P(k)

Conclusion: The toy P(k) matches the baseline P(k) almost perfectly; describing the correlation as “extremely high (≈1)” is fully justified.

5. Theoretical vs Empirical Parameter Differences

Using 06_Data_and_Scripts/Results/param_comparison_theoretical_vs_empirical.csv together with the recomputed Results/param_mismatch_summary.csv:

Conclusion: The statement that “parameters like amplitude, tilt_ns, and peak_ell show large discrepancies (some exceeding 80%) between theory and empirical fits” is exactly borne out by the CSV values, and the new param_mismatch_summary.csv quantifies how extreme these mismatches are in σ units.
