## Overall Assessment

**Status:** ✅ **PRODUCTION READY**

The story context XML for Story 2-7 (TLS/SSL Certificate Handling) is **complete and comprehensive**. All 10 checklist items passed with strong evidence:

1. ✓ Story fields captured exactly from draft
2. ✓ All 8 ACs match story draft verbatim (no invention)
3. ✓ All 10 tasks captured with AC traceability
4. ✓ 10 relevant docs with paths and contextual snippets
5. ✓ 6 code artifacts with clear reasons and line hints
6. ✓ 5 interfaces/API contracts documented with signatures
7. ✓ 12 constraints covering security, patterns, ADRs, Story 2.6 carryover
8. ✓ 7 dependencies (6 Python packages + 1 stdlib) with versions and usage
9. ✓ Complete testing section: standards, 5 locations, 15 AC-mapped test ideas
10. ✓ Valid XML structure following template format exactly

**Developer handoff readiness:** The context provides everything needed for implementation - clear requirements, existing code references, integration points, constraints, testing guidance, and Story 2.6 carryover items (health check initialization, legacy cleanup). No gaps or ambiguities detected.

**Next steps:** Story is ready for development (status: ready-for-dev). Developer can begin Task 1 (TLSContextManager module creation) with full context available.
