APA — Evidence-Driven Risk Discovery
A production risk-discovery workflow with scoped expansion and evidence provenance.
APA is an evidence-driven risk-discovery pipeline for e-commerce content. I led the system design, implementation, and production integration.
- Joint content and product signals focus discovery on relevant evidence.
- Scope-aware expansion follows related content while preserving the connection to its source evidence.
- Deduplication and provenance distinguish directly observed evidence from propagated candidates.
- Review gates and recorded outcomes support controlled iteration.
Workflow measurements showed approximately 17× higher candidate throughput. Independent human validation and population-level recall remain separate evaluation questions.
