## 2. Vendor 目錄結構（離線打包依賴）

**關鍵：所有第三方二進位都放進 `vendor/`，由建置腳本首次執行時透過 `make vendor-sync` 下載。一旦下載就 cache，之後 offline build。**

### 2.1 `make vendor-sync` 腳本（首次 setup 用）

```bash
#!/usr/bin/env bash
# scripts/vendor-sync.sh - 下載所有第三方依賴到 vendor/
set -e

VENDOR=vendor
mkdir -p $VENDOR/{python,wheels,ffmpeg,yt-dlp,drivers}

curl -L -o $VENDOR/python/cpython-3.12-macos-x64.tar.gz \
  "$PBS_BASE/cpython-$PBS_PY+$PBS_VERSION-x86_64-apple-darwin-install_only.tar.gz"
curl -L -o $VENDOR/python/cpython-3.12-windows-x64.tar.gz \

  "$PBS_BASE/cpython-$PBS_PY+$PBS_VERSION-x86_64-unknown-linux-gnu-install_only.tar.gz"

# 2. Python wheels（用每個平台的 Python 預先下載）
# 注意：必須在對應平台上跑 pip download 才能拿到正確的 wheel tag
# 這裡假設使用者已在 macOS 機器上跑過：
#   pip download -d vendor/wheels/macos-x64 \
#     --platform macosx_11_0_x86_64 --python-version 3.12 --only-binary=:all: \
#     numpy opencv-python-headless pyusb
# KneronPLUS wheel 另外手動放進去（從 edge-ai-platform/installer/wheels/ 複製）

cp -n ../edge-ai-platform/installer/wheels/macos/KneronPLUS*.whl $VENDOR/wheels/macos-x64/ 2>/dev/null || true
cp -n ../edge-ai-platform/installer/wheels/linux/KneronPLUS*.whl $VENDOR/wheels/linux-x64/ 2>/dev/null || true
cp -n ../edge-ai-platform/installer/wheels/windows/KneronPLUS*.whl $VENDOR/wheels/windows-x64/ 2>/dev/null || true

# 3. ffmpeg LGPL
FFMPEG_VER="7.1"
# macOS
curl -L -o /tmp/ffmpeg-mac.zip "https://evermeet.cx/ffmpeg/ffmpeg-$FFMPEG_VER.zip"
unzip -o /tmp/ffmpeg-mac.zip -d $VENDOR/ffmpeg/macos-x64/
# Windows（BtbN LGPL build）
curl -L -o /tmp/ffmpeg-win.zip \
  "https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n$FFMPEG_VER-latest-win64-lgpl-shared-$FFMPEG_VER.zip"
# 解壓 ffmpeg.exe 與需要的 DLLs 到 vendor/ffmpeg/windows-x64/
# Linux
curl -L -o /tmp/ffmpeg-linux.tar.xz \
  "https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-amd64-static.tar.xz"
tar -xf /tmp/ffmpeg-linux.tar.xz -C /tmp/
cp /tmp/ffmpeg-*-amd64-static/ffmpeg $VENDOR/ffmpeg/linux-x64/

# 4. yt-dlp
YTDLP_BASE="https://github.com/yt-dlp/yt-dlp/releases/latest/download"
curl -L -o $VENDOR/yt-dlp/yt-dlp_macos "$YTDLP_BASE/yt-dlp_macos"
curl -L -o $VENDOR/yt-dlp/yt-dlp.exe "$YTDLP_BASE/yt-dlp.exe"
curl -L -o $VENDOR/yt-dlp/yt-dlp "$YTDLP_BASE/yt-dlp"
chmod +x $VENDOR/yt-dlp/yt-dlp_macos $VENDOR/yt-dlp/yt-dlp

# 5. WinUSB driver（從 edge-ai-platform 複製）
cp -r ../edge-ai-platform/installer/drivers/* $VENDOR/drivers/

echo "✅ Vendor sync complete."
```

**vendor/ 是否進 git？（第三輪使用者決策 Q-D=D2：不進 git）**

- **整個 `vendor/` 目錄加入 `.gitignore`**，不進版本控制
- 所有第三方二進位（Python tarball、ffmpeg、yt-dlp、KneronPLUS wheel、WinUSB driver 等）都由 `make vendor-sync` 從來源下載
- 開發者第一次 clone 後執行 `make vendor-sync` 即可取得完整 vendor tree
- CI 亦在每次 build 前跑 `make vendor-sync`（可加 cache 加速）
- 保留 `vendor/.gitkeep`（或 `vendor/README.md`）讓空目錄存在並說明取得方式
- 優點：repo 保持小；缺點：依賴外部下載來源可用性（由 R8 風險緩解處理 — pbs 下載 URL pin 版本 + 備援 mirror）

**`.gitignore` 片段：**

```gitignore
# 第三方依賴（由 make vendor-sync 下載，不進 git）
/vendor/**
!/vendor/.gitkeep
!/vendor/README.md

# 建置產出
/dist/
/visiona-local/build/
/visiona-local/payload/
```

## 3. CI 策略（選配，第一版可純手動）

### 3.1 建議：GitHub Actions matrix build

            macos-installer/*.dmg
            windows-installer/*.exe
            linux-installer/*.AppImage
```

### 3.2 第一版可以不用 CI

MVP 階段可以**純手動**：
- 在自己的 Mac 上 `make installer-macos`
- 用 UTM / Parallels VM 跑 Windows 11 `make installer-windows`
- 用 Docker / multipass VM 跑 Ubuntu 22.04 `make installer-linux`

CI 可以等 M5 之後再做。

---

## 4. 版本號管理

單一來源：Git tag `v1.0.0` → 透過 Makefile `VERSION` 變數傳入：
- Go binary：`-ldflags "-X main.Version=$(VERSION)"`
- Wails: 讀取 `wails.json` 的 `info.productVersion`
- Installer 檔名：`visiona-local-v1.0.0-*`

**建議版本策略：**
- `v0.x.x`：MVP / alpha
- `v1.0.0`：第一個對內部釋出的穩定版
- 每個 milestone 對應一個 minor（M1→v0.1.0、M2→v0.2.0、M6→v1.0.0）

---

## 5. 開發迭代速度優化

- **dev 模式不用 payload**：`make dev` 直接 `go run` server + `pnpm dev` 前端，不過 Wails app
- **dev 模式用系統 Python**：`--python-mode=system` 避免每次都要解壓內嵌 runtime
- **前端改動不用重 build server**：`go run main.go --dev` 時 `web/out` 不啟用，前端直接連 3000 port
