Structured Risk Evaluation

Use this sub-skill for synthetic or approved tabular release workflows that need quasi-identifier discovery, k-anonymity, l-diversity, t-closeness, differential privacy aggregates, membership risk, anonymized output validation, and compliance evidence.

Route elsewhere when the task is about

• Free-text PHI or PII redaction → deidentification-privacy.
• Clinical entity extraction or grounding → clinical-extraction-grounding.
• Service deployment, transport, or adapter wiring → interoperability-serving.

Core surfaces

• openmed.structured
• openmed.risk
• openmed.eval
• openmed.compliance
• CLI families: risk, audit, compliance, benchmark, eval, gates, calibrate

Safe workflow

1. Discover candidate direct identifiers, quasi-identifiers, sensitive columns, and the privacy unit with scan_table or profile_structured_table.
2. Review the policy explicitly; do not infer threshold values.
3. Assess the raw table with assess_release, analyze_k_anonymity, assess_population_risk, or the DP and membership helpers that match the task.
4. Anonymize with anonymize_release or anonymize_table.
5. Re-read the materialized release and validate with validate_released_output.
6. Package aggregate-only audit/compliance evidence and, when needed, feed it into release gates and dashboards.
7. Keep all examples synthetic. Never depend on DUA-restricted rows, raw PHI, or deployment-time services.

Output expectations

• Aggregate JSON summaries only.
• Evidence files may include Markdown and JSON, but never raw cell values.
• Release artifacts should be materialized locally, reread, and validated before review or gating.
