**Strategy & roadmap:** Define the labeling/annotation strategy, taxonomy stewardship, and quality framework aligned to fraud risk priorities and partner roadmaps.

**Active learning & data quality:** Design sampling/uncertainty strategies, gold sets, and label accuracy.

**Programmatic labeling:** Introduce fragile supervision, heuristics, and graph-derived signals to pre-label data.

**Detection enablement:** Partner with engineering and data scientists to integrate labels into feature stores, model training, rules evaluation, and shadow tests.

**Cross-functional influence:** Translate ambiguous fraud patterns into clear label definitions and decision rubrics; align with Product, Engineering, and other stakeholders.

**Executive communication:** Report business impact and influence prioritization decisions.
