+## 2026-06-24｜Tsenyang Website dev baseline owner decision package
+
+**背景**：Blocked products pick list 將 Tsenyang Website 排為第二候選。本輪只讀 `/Users/ogt/tsenyang-website`，確認 internal remote 其實可讀，並把阻塞從 internal unknown 收斂為小 dirty review；不 commit、不 branch、不 push、不讀 `.env` 或 secret value。
+
+**Readback**：
+- Local branch `main`，HEAD `b369ed8cb6666e8ddaa2d31e1418a02794fdea9d`，upstream `origin/main`。
+- Remote main 同為 `b369ed8cb6666e8ddaa2d31e1418a02794fdea9d`；remote `dev` missing。
+- Tracked dirty `6`：`public/og/taiwan-ai-agent-checklist.*`、`taiwan-ai-agent-webinar.*`、`taiwan-partner-kit.*` 的 PNG / SVG。
+- Untracked `3`：`outputs/.DS_Store` 與兩個 PPTX generated outputs。
+- `git diff --check` passed；shortstat `6 files changed, 163 insertions(+), 63 deletions(-)`。
+
+**新增文件 / snapshot**：
+- `docs/operations/tsenyang-website-dev-baseline-owner-decision.snapshot.json`
+- `docs/operations/TSENYANG-WEBSITE-DEV-BASELINE-OWNER-DECISION-2026-06-24.md`
+
+**下一步**：需要 owner 批准後，才能從 clean main 建立 remote `dev`；OG assets 應進 task branch，`outputs/.DS_Store` 不納入，PPTX 需 owner 明確標成 release artifact 才可納入 source control。

 ## 2026-06-24｜ClawBot / OpenClaw dev baseline owner decision package
 
 **背景**：Blocked products owner pick list 指出 ClawBot / OpenClaw 是最小可審核面：tracked dirty `2`、untracked `0`。本輪只讀 ClawBot repo，確認兩檔 drift 與 `STANDBY_MODE` 設定是否完整，不 commit、不 branch、不 push、不讀 `.env`、不讀 Telegram token value。

+
+## 判定
+
+Tsenyang Website 是第二個可快速推進的候選：remote main 與 local HEAD 相同，阻塞只剩 remote `dev` 缺失和小範圍行銷素材 dirty review。
+
+仍不能直接推，因為 `outputs/` 內有產出檔和 `.DS_Store`，需要 owner 決定它們是否應進 source control。建議流程：
+
+1. 批准後，從 clean main 建立 remote `dev`。
+2. 從 `dev` 切 `codex/<task>` 處理 6 個 OG asset。
+3. `outputs/.DS_Store` 不納入。
+4. PPTX output 只有在 owner 明確標成 release artifact 時才納入，否則應走 Drive / artifact storage。
+
+## 安全邊界
+
+- 未讀 `.env`。
+- 未讀 secret value。
+- 未修改 Tsenyang repo。
+- 未建立 branch、commit 或 push。
+- 未同步 generated outputs。
