## Recommendations

### Must Have (Critical)
✅ All critical issues fixed - no blockers remain

### Should Have (Important)
✅ All important issues fixed - story ready for development

### Nice to Have (Optional)
1. Consider adding Task 11 for README.md comprehensive documentation (currently covered in Task 9 but could be expanded)
2. Consider adding explicit reference to Story 2.5 ReconnectionManager integration for TLS errors (mentioned in Dev Notes but could be more prominent)
3. Consider adding performance benchmarking subtask to Task 8 (integration tests) for TLS overhead measurement

## Validation Conclusion

**Final Outcome:** ✅ **PASS** - All quality standards met

Story 2.7 has been enhanced with 3 critical fixes and now demonstrates:
- **Perfect traceability**: All ACs, tasks, and citations properly linked
- **Complete continuity**: Story 2.6 learnings, files, and unresolved items documented
- **Comprehensive coverage**: All source documents cited with section-level specificity
- **Production readiness**: Security requirements, error handling, and testing fully defined

**Story Status:** Ready for story-context generation or development

**Next Steps:**
1. Run `*story-context` workflow to generate dynamic Story Context XML
2. Mark story as "ready-for-dev" via `*story-ready-for-dev` workflow
3. Developer can begin implementation with complete context and guidance
