Produce quantitative corroboration for risk hypotheses.

Inputs

• Required: evidence-table.md, risk-register.md
• Optional helper: statements fetched via fetch_financial_sheets.py

Workflow

1. Validate input artifact schemas.
2. Build period-aligned metric dataset.
3. Compute core forensic ratios and deltas.
4. Link each anomaly to risk_id and category.
5. Write artifact ratio-diagnostics.md.

Required Output Artifact

Write ratio-diagnostics.md with required columns defined in ../sec-shenanigans-orchestrator/references/bundle-contract.md.

Rules

• Favor trend breaks over one-period thresholds.
• Require at least 4 quarters for directional claims when data exists.
• Emit data-quality limitations explicitly.
