Gap analysis found the POC's designed-but-unbuilt strategic gaps: ABAC
authorization (ADR-0002/PRD-0002 phase P1), no e2e coverage, unproven
i18n second-locale seam, thin resilience seams (correlation-id,
idempotency, retry), and in-memory-only persistence. Each WP is grounded
in the current code (file paths + line numbers), not just the analysis.
Also corrects PRD-0001's stale 'Proposed' status header — the Mijn
aanvragen vertical is fully built.
