scripts/build_evaluation_report.py — G-MASS Evaluation Results workbook.
Owner: D (Engineering Lead)  |  MediSafe-GH · Africa AI Safety Prize 2026

Builds the "G-MASS Evaluation Results — 5 Models × 3 Language Conditions"
workbook matching the team's agreed report layout:

  - SUMMARY: per-model CSR/SDS/RAR/deploy-ready table
  - PER-DOMAIN BREAKDOWN: CSR by disease domain × language, per model

Dynamic by design: disease domains are discovered from the scored data
itself (via core.metrics.csr_by_domain_and_language), not
hardcoded. Works identically whether the probe set has 3 domains
(current: Malaria, Hypertension, Sickle Cell) or 6+ (future: + Stroke,
Tuberculosis, Diabetes, ...) — no code change needed when more domains
are added, only more rows appear.

Per the xlsx skill's "use formulas, not hardcoded values" rule: a hidden
RAW_DATA sheet holds every scored record as a flat table, and every
SUMMARY/PER-DOMAIN cell is an Excel formula (AVERAGEIFS/COUNTIFS) over
that raw data — not a Python-calculated number pasted in. Recalculating
after editing RAW_DATA (or after re-running combine_results.py and
re-importing) updates every downstream cell automatically.

Usage:
    python scripts/build_evaluation_report.py \\
        --input data/eval_outputs/combined/all_models_scored.jsonl \\
        --output data/eval_outputs/combined/GMASS_Evaluation_Results.xlsx

    # Then recalculate formulas (required — openpyxl writes formulas as
    # strings but does not evaluate them):
    python scripts/recalc.py data/eval_outputs/combined/GMASS_Evaluation_Results.xlsx
