# DOUBLE-CHECK SYNTHESIS — Harness-11 adap (2026-06-18-h11-doublecheck · `wf_a0b68d2f-30e`)

> 3× reviewer (read-only, adversarial ∥). Em-main scribe @P3. **VERDICT: ✅ PASS — 0 blocker.** Re-verify commit `e70c046` + regression của refinement em-main áp sau REVIEW-1.

## DA1 — over-suppression regression → FAILED-no-StructuredOutput → **em-main self-gate CLOSED**
- Reviewer lane parallel[0] không trả StructuredOutput (lỗi #53 schema-force tái diễn).
- **Em-main self-gate (recovery-pattern):** inject prose fake-drift "99 migration" (KHÔNG table-row/version/historical) → detector **CAUGHT** "99 migration but canonical=55" → revert clean. → **no over-suppression, runtime-proven.**
- Bonus: detector pure-ASCII (Python scan 0 non-ASCII — gotcha #30 clean) · PS parse OK · exit 0 · 26 flag.

## DA2 — committed-state correctness → **PASS**
- B1 **exactly 11** pointer-conversion (grep -c = 11). root CLAUDE.md:53 **tail byte-identical** (`sed -n '53p'` ends "...phiếu cũ.)" = old) → 0 load-bearing prose loss; chỉ leading count-phrase swap + S74/S73 additive prefix.
- ef-core Mig 54/55 rows = **tên migration THẬT trên disk** (`AddPeSuggestedAndApprovedPrice` + `AddCcmNoteToPeWorkItemBudget` .cs EXIST).
- 0 stale-count residual (grep 53mig/306test/68gotcha/93bảng = 0). cadence §2.1.3/§L.b cú-pháp đúng, path tồn-tại + run clean. engine-doc line-ref accurate (D5=:67, hmw.js:76/103/111, budget.json:19).
- 2 MINOR (đã FIX): agents/README "(pending)" stale + C2 FP CLAUDE.md:84/:90.

## DA3 — containment + regression → **PASS** (0 blocker/0 major/1 minor-info)
- Q1 0 production code (grep src/|fe-* = 0). Q2 run-trace đủ (audit/review NO sub = read-only em-main-scribe ✓ · implement có sub-task-0/1 = general-purpose Write ✓ · ledger CLOSE-beat all prior). Q4 single-writer (0 sub MEMORY.md residual · .archive-strikes.json absent). Q5 budget.json pure-additive (measured/tiers/last_sleep_at untouched).
- **Q3 broadcasts byte-verified:** recompute INBOX body=`b2a2fc1cf399` (==_index ==frontmatter), whole-file=`318ff9f6` (==commit-msg); OUTBOX body=`7fa1b53a61ae` (==_index ==frontmatter). KHỚP TUYỆT-ĐỐI.
- **REGRESSION over-suppression HUNT (độc-lập confirm self-gate):** enumerate cái C2-skip che = per-item frozen (ef-core "Mig 12→10 bảng") + Session-N historical + CLAUDE.md "88 table"==canonical — KHÔNG cái nào là live-aggregate-state-count. Cả 11 prose-drift VẪN bắt. C1 normalize verified 2 chiều (genuine-dangling vẫn flag + prefix-differ vẫn flag). **NO real drift hidden.**
- Anti-finding: C3 console mojibake "D? tr�" = console-codepage Bash-capture artifact, KHÔNG script bug ([Console]::OutputEncoding=UTF8 render "Dự trù PRO" đúng; Select-String so-sánh UTF-8 chính-xác).

## Em-main actions post-doublecheck
1. ✅ self-gate fake-drift (close DA1) — no over-suppression, runtime.
2. ✅ +C2 "test project" skip (line 90 FP gone, 27→26) — ASCII clean.
3. ✅ agents/README "(pending)" → run-id thật (review `wf_d7ca1ff8-942` + doublecheck `wf_a0b68d2f-30e`).
4. ⚠️ Tree-line FP-skip ATTEMPTED rồi REVERT (literal box-glyph = gotcha #30 trap; \u-escape edit bị tool render-normalize → bỏ, line 84 "6 test" giữ làm documented soft-net FP, advisory exit-0 harmless). **Bài học: KHÔNG đưa box-glyph vào .ps1 — kể cả qua Edit tool (normalize).**

## VERDICT: PASS — committed-state đúng, refinement 0-regression (triple-confirmed self-gate+DA2+DA3), containment clean. Sẵn-sàng checklist-verify + push.
