+
+## REVIEW (Workflow `wf_b7f3c8ac-b53`, 3 free-text lane — KHÔNG ép-schema per lesson S73)
+- Part-A **PASS** · Part-B **PASS** · Honesty **HONEST**.
+- Bắt **2 CONCERN** (review→fix loop): (1) anchoring "matches AI_INFRA" → reframe SE-ước-riêng-trùng-vì-cùng-toolset-KHÔNG-mượn-số · (2) attribution sai `measure-agent-memory.ps1` (script đó chỉ đo agent-memory-tier byte) → sửa "persona đo TRỰC-TIẾP `Get-ChildItem`". Cả 2 **đã fix**.
+- Bonus: review đọc **stale `measured` block** (S71-seed) → misread "no sub over cap" → em refresh `measured` S71→S81 fresh (frontend-designer 26129 + test-specialist 27723 OVER cap, đúng WATCH).
+
+## Verify
+- `memory-archive-gate.ps1` value-protect FLAG runtime-fired (test-specialist) + **A7 GATE PASS 217/217** (integrity post-edit).
+- `governance-detectors.ps1` = **26-flag baseline** (0 new vocab-fork/broken-link từ edits).
+- budget.json JSON valid (3 ConvertFrom-Json check).
+
+## Bài học (NEW)
+- **Independent review bắt honesty-imprecision self-review ship:** số-trông-mượn (21K trùng AI_INFRA) + tool-cite-lỏng (sai script). Cả 2 disclosed-không-giấu nhưng skeptic-cold đọc ra "weakest link". Fix = tighten wording để honest-thing = obviously-honest. → cùng họ `feedback_canonical_spec_over_broadcast` (pull-canonical-đừng-phỏng-theo).
+- **Stale-config đánh-lừa cả reviewer:** reviewer reason off file-says → stale `measured` block khiến nó misread "no sub over cap". Config-staleness mislead không chỉ người mà cả self-verification. → §2.1.2 budget-audit phải re-measure ĐẦU mỗi adap đụng budget.json.
+- **Value-gate = mechanized FLAG nhưng EXCLUDE = convention (D6):** detect deterministic (đây là gotcha) → mechanize FLAG; decision (giữ-hay-archive) = judgement → em-main. Auto-exclude = cross "script tự-ghi-memory" = mối-nguy #1 cố-ý-tránh.
