Layer Boundary Auditor

Type: L3 Worker

L3 Worker that audits architectural layer boundaries and detects violations.

Purpose & Scope

• Read architecture.md to discover project's layer structure
• Detect layer violations (I/O code outside infrastructure layer)
• Detect cross-layer consistency issues:
  • Transaction boundaries (commit/rollback ownership)
  • Session ownership (DI vs local)
• Check pattern coverage (all HTTP calls use client abstraction)
• Detect error handling duplication
• Return violations list to coordinator
