    nota: |
      Coverage REAL actualizado por Architecture-Analyst (2025-11-23).
      Epic PARCIAL (40% completitud) - Solo LTI 1.3 auth y basic launch implementados.
      Tests mínimos en servicios completados (lti-auth, lti-launch).
      Gap actual requiere plan de mejora cuando se complete implementación (Q2 2026).
