Split 5 oversized files (501-583 LOC each) into focused units all under 500 LOC: - license_policy.go → +_types.go (engine logic / type definitions) - models.go → +_intake.go, +_assessment.go (enums+domains / intake structs / output+DB types) - pdf_export.go → +_markdown.go (PDF export / markdown export) - escalation_store.go → +_dsb.go (main escalation ops / DSB pool ops) - obligations_registry.go → +_grouping.go (registry core / grouping methods) All files remain in package ucca. Zero behavior changes. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
