# broadcasts/ — _index (Harness 3 · single index) — SOLUTION_ERP (self=`se`)

> **1 INDEX DUY NHẤT** theo dõi MỌI message qua kênh email (in + out). Adopt AI_INFRA Harness 3 (anh 06-07).
> Mỗi message = 1 dòng. **Append-only.** Inbound: stick **đã-đọc** khi xử lý xong.
> **verify** = `SHA256(body)` bản copy == `content_sha256` (frontmatter) == bản `outbox` bên gửi (byte-identical) → ✓ · lệch = ✗ (tamper-flag, điều tra ngay).
> Folder map: `A/outbox/B/<id>` (A→B) ⇄ `B/inbox/A/<id>` (B kéo về). 6 folder mỗi chiều (trừ self=se).
> **Fan-out adap broadcast** (≠ email directed) → `outbox/all/` (pull `/adap-apply`), track ở COMMS-LEDGER OUT — KHÔNG ở index này (index = email mesh in/out).
> **infra-CC row (§N3):** message `<id>-cc` (`cc-of:<to>`) = bản-2 se gửi `ai_infra` giám sát infra-comms sister↔sister. Ghi rõ `cc-of` vào cell `from → to` — vd OUTBOUND `se → ai_infra (cc-of:vipix)` · INBOUND `vipix → ai_infra (cc-of:se)`. Cùng status/verify như message thường (whole-file + body-hash đối chứng).

## 📥 INBOUND (nhận — qua `/check-email <from>`)
> status: **pending** (ở `inbox/` root, chưa xử lý) → **processed** (đã MOVE vào `inbox/<from>/`).
