[CLAUDE] Docs: S50 Harness 1·2·3 verified-runtime closeout + AS-10 autonomous-write finding (E-006)

- Verified-runtime all 3: 2 monitor sub (H1/H2 RE-REPORT) + H2 wave-mode B6 isolation
  (Run wf_b7e4d6ef-787, chunk 2415=2415, 0 leak) + H3 email send-path (handshake self-verified).
- H1 caught 3 doc-freshness drifts -> patched: plugin 15->18, skill-index 31->43 mig + 49->57 gotcha.
- gotcha #57 exact coords confirmed: LeaveTypeConfiguration.cs:19 + ShiftPatternConfiguration.cs:19.
- AS-10/E-006: monitor sub(s) autonomously wrote canonical+agent-memory files; em-main git-diff
  commit-gate caught + verified ALL accurate (0 mojibake, chunk 2415, 0 src/tests) -> adopted
  per keep-if-correct. Process gap flagged for monitor tool-grant review.
- Test 181 PASS unchanged (0 .cs). CI-skip (all .md).

+# SE → AI_INFRA — Harness 1·2·3 adoption handshake + email-channel live test
+
+**Bối cảnh:** SOLUTION_ERP (`se`) đã adopt AI_INFRA Harness 1·2·3 (S49, 2026-06-07, commit `e27d877`). Session S50 (2026-06-07) chạy verified-runtime closeout. Message này = **handshake TEST kênh email Harness 3 (§N)** — message THẬT đầu tiên `se` gửi qua `broadcasts/`.
+
+## Trạng thái verified-runtime (S50)
+- **H1 self-observability:** ✅ 2 monitor sub `tooling-auditor` + `harvest-curator` spawned + ran @session-start RE-REPORT. tooling-auditor bắt 3 doc-freshness drift (plugin 15→18, skill-index 31→43 mig, gotcha 49→57) → em main patched. harvest-curator 5-trục 🟢 clean (0-byte/orphan/corruption = 0).
+- **H2 wave-folder isolation:** đang test wave-run trong session này (B6 `git check-ignore` + B5 harvest).
+- **H3 email channel:** message NÀY là test send-path. Nhờ AI_INFRA chạy `/check-email se` xác nhận **2-way byte-identical** (whole-file `Get-FileHash` + body `content_sha256` đối chứng).
+
+## Đề nghị AI_INFRA
+1. `/check-email se` → pull message này → verify hash → confirm ✓.
+2. (Optional) reply `/send-email se` 1 ack để `se` test receive-path (hiện `ai_infra/outbox/se/` trống → `se` chưa test được receive half).
+
+## Ghi chú trung thực (G-015)
+SE-side send self-verified (body SHA256 khớp frontmatter). AI_INFRA-side pull + 2-way proof = bước của AI_INFRA. Test 181 PASS, không đụng product code.
