# /send-email <to_project> — gửi email cross-project (Harness 3 · self=`se`)

> 🔴 Kênh DUY NHẤT (§N) · chỉ ghi repo MÌNH (§J2). self=`se`. Detail: AI_INFRA `broadcasts/README.md` §Harness 3 (pull `cross_project_search`).

## Tham số
- `$1` = to_project (BẮT BUỘC) ∈ 6 project ≠ `se` (self/unknown → ABORT).
- `$2` = category ∈ `Governance·Agent·Memory·Rag·Mcp·Skill·Cmd·Coord` (default `Coord`). ✅ *infra-CC ACTIVE: `category` ≠ `Coord` + `to` ≠ `ai_infra` → auto bản-2 vào `outbox/ai_infra/` (bước 6b) để AI_INFRA giám sát infra-comms.*

## Project-path map (7 project — se dùng 6 ≠ self · path-coupling, web-migration sẽ bỏ)
| id | broadcasts root |
|---|---|
| ai_infra | `D:\Dropbox\CONG_VIEC\AI_INFRA\broadcasts` |
| vipix | `D:\Dropbox\CONG_VIEC\VIPIX_MULTISITE_PROJECT\broadcasts` |
| se | `D:\Dropbox\CONG_VIEC\SOLUTION\SOLUTION_ERP\broadcasts` (← self) |

## Quy trình
1. **Validate** `$1` ∈ 6 others (≠ `se`/unknown) → else ABORT.
2. **Soạn body** markdown theo intent.
3. **id** = `<YYYY-MM-DD>-se-to-<to>-<slug>` (unique).
4. **content_sha256** = `SHA256(body)` **canonical** (strip 1 leading newline — Y HỆT receive): `(($txt -split "(?m)^---\s*$",3)[2] -replace "^\r?\n","")` → SHA256-UTF8.
5. **Frontmatter:** `id · from: se · to: <to> · category · type: broadcast|update|fix|report|request|coord · date · content_sha256 · nac: sent`.
6. **Ghi** `broadcasts/outbox/<to>/<id>.md` (**Write tool**, KHÔNG shell-write — chống mojibake). [chỉ repo MÌNH §J2]
6b. **infra-CC** (Harness-3 §N3) — NẾU `category` ∈ {Governance·Agent·Memory·Rag·Mcp·Skill·Cmd} (≠`Coord`) VÀ `to` ≠ `ai_infra`: ghi **bản-2** `broadcasts/outbox/ai_infra/<id>-cc.md` (Write tool — repo MÌNH = §J2-safe, KHÔNG ghi inbox ai_infra) — **body + `content_sha256` Y HỆT** primary; frontmatter `id: <id>-cc · from: se · to: ai_infra · cc-of: <to> · category · type · date · content_sha256 · nac: sent`. (Đã có `outbox/ai_infra/.gitkeep`.) → AI_INFRA pull qua `/check-email se`.
7. **Log** append `broadcasts/_index.md` §OUTBOUND (+ 1 row tag `cc` nếu có bản-2).
8. **Báo.** KHÔNG tự relay — bên nhận tự `/check-email se`.

## Luật
🔴 §N single-channel · 🔴 §J2 chỉ-ghi-repo-mình · `from`+`to` BẮT BUỘC · id unique · folder khớp `to` · infra-CC bản-2 (category≠Coord → `outbox/ai_infra/`, ghi repo MÌNH = §J2-safe). Outward content → reviewer-gate (no-overclaim G-015) trước relay.
