[CLAUDE] Docs: Harness-11 double-check ×2 + finalize report (anh giao)

- DOUBLE-CHECK wf_a0b68d2f-30e (3× reviewer): committed-state e70c046 PASS — B1 ×11 exact, root CLAUDE.md:53 tail byte-identical, broadcasts hash recompute khớp, single-writer clean. Over-suppression regression CLEAN: DA1 no-return → em-main self-gate fake-drift "99 migration" CAUGHT (runtime) + DA2/DA3 độc-lập confirm
- CHECKLIST-VERIFY wf_39cd4cbe-f07 (3× investigator-codebase): completeness-gate H11 FORMAL ĐẠT — B 4/4 + C 5/5 + D 11/11 đủ-trọn (function-floor MET), A 🟡 tailored; D5/D6/D7 explicit + D8 one-direction codify = YES
- detector refine: +C2 "test project" skip (27→26); tree-skip reverted (gotcha #30 box-glyph trap, kể cả qua Edit render-normalize); detector pure-ASCII verified
- agents/README "(pending)"→run-id; adap-report + outbox email +double-check section (hash 2316773229f2)
- 0 production code; state THẬT giữ nguyên (Mig 55 · 88 bảng · 339 test · gotcha 69 · bundle BYF5vIMJ/CB-tiRxd)

+# 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<74>" = 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.
