## NWT N14.12 verify (Phase β cement实证)

- mm_orders + mm_quotes 表 DROPPED ✓
- exchange_offers 3660 rows preserved (no data loss) ✓
- exchange_offers 41 cols intact ✓
- /api/exchange/offers 1986 active, single source of truth ✓
- broker DM state machine 不破 (back → 主菜单 reply ~3s) ✓
- N14.11 BUY E2E real chain settle 70s 正常 (vs sub#3b stuck 27 min)

## 3 KI sediment (永久 anchor in milestone-phase-alpha-real-e2e-5-18.md)

1. **delete script boundary 吞 imports** (sub#3b 真因): 大段 deletion 必 anchor-based (function 名 / unique 注释 marker), 不 line-range splice. delete 前必 print before/after 5 行 context preview.

2. **queue-failed silent skip mark settled** (KI-12 [[feedback_silent_skip_pattern_invariant_test]] 第 N+1 次): fail path 必 mirror 已 correct path. KAS path L287 学 EVM path L310-326 3-retry + DM + early return pattern. helper fail path 必同 commit 加 invariant test.

3. **real chain DM E2E catches mock/SQL audit 漏 regression** ([[feedback_real_test_only_truth]] 第 4 次实证): N14.7 sub#3b regression 是 mock/SQL audit 漏, NWT 真链 BUY E2E 才暴 stuck. N7.3 false-positive lesson continuation — 真测才是 ground truth, 不该用 SQL count audit 当 verify.
