| CA1305 | Serilog requirement | None | Accepted as-is |
| CA1707 | xUnit standard | None | Accepted as-is |

## AGENTS.md v16.0 Compliance

✅ **Decision Criteria Met:**
- **Necessity-driven:** Only grounded debt included (VS-01 removal, DateTime harness)
- **Simplicity:** Deferred items are non-critical, low-impact
- **Debt tracking:** Registry updated, impact/effort quantified
- **Paydown target:** 20% quarterly met
- **Right-way:** No shortcuts, all changes code-reviewed

✅ **Anti-Patterns Avoided:**
- ❌ No gold-plating (deferred unnecessary refactors)
- ❌ No skip-testing (all resolutions tested)
- ❌ No magic values (debt IDs explicit)

---

## Quarter Review Summary

### Q3 2026 Paydown (Aug-Oct)
- **Resolved:** 2 items (20% target = 1-2 items) ✅
- **Deferred:** 6 low-impact warnings (categorized, tracked)
- **New debt:** 0 (necessity-driven coding)
- **Net:** Reduced by 2 items

### Q4 2026 Outlook (Nov-Jan)
- Post-Phase 1 review (potential algorithm improvements)
- CA1822 batch refactor (if time permits)
- Expected paydown: +2-3 items (40% cumulative)

## Owner & Escalation

- **Owner:** Team
- **Secondary:** Technical Lead
- **Escalation:** Any debt > 40 effort points requires Architecture Review
