+# Codex Start Here Acceptance Ledger Sync Readback
+
+- generated_at: `2026-06-24T14:52:00+08:00`
+- result: `synced`
+- MacBook Pro: `MacBook-Pro.local`
+
+## 同步內容
+
+只同步兩個 handoff 檔案：
+
+- `~/.codex/CODEX-START-HERE.md`
+- `~/.codex/codex-workstation-sync-dashboard.snapshot.json`
+
+沒有同步：
+
+- `~/.codex/auth.json`
+- `~/.codex/*.sqlite`
+- `~/.codex/sessions`
+- raw Codex / ChatGPT conversations
+- `.env`
+- runtime volumes
+- raw `.git` directories
+
+## Readback
+
+| Workstation | Start Here SHA256 | Dashboard SHA256 |
+|-------------|-------------------|------------------|
+| Mac Mini | `1e1a53950bdd1ddbe9aa8edb5a6d5df5fbcbf92240f64deeb60c5000b3878706` | `af50d4ef1493f58de81f5b50d98632e9e9b1cf0ec9282e59c36d9007723c77e0` |
+| MacBook Pro | `1e1a53950bdd1ddbe9aa8edb5a6d5df5fbcbf92240f64deeb60c5000b3878706` | `af50d4ef1493f58de81f5b50d98632e9e9b1cf0ec9282e59c36d9007723c77e0` |
+
+MacBook Pro markers：
+
+- `blocked_product_response_acceptance_ledgers=8/8`
+- `blocked_product_owner_accepted=0/8`
+- `blocked_product_remote_dev_ready=0/8`
+- `artifact_sync_synced=2`
+- dashboard `blocked_product_owner_response_acceptance`
+- dashboard `blocked_product_owner_response_acceptance_ledger_count=8`
+
+## 判定
+
+Mac Mini / MacBook Pro 現在看到同一份 Start Here 與 workstation dashboard，且兩邊都包含 blocked product acceptance ledger 狀態。這代表 handoff / 開工上下文同步，不代表 raw Codex 歷史視窗同步，也不代表任何 blocked product 已可建立 remote `dev`。
+
+## 邊界
+
+- 沒有同步 auth、SQLite、sessions、raw conversations、`.env`、runtime volumes 或 raw `.git`。
+- 沒有修改任何產品 repo。
+- 沒有建立 product branch、remote `dev` branch 或 Gitea repo。
+- owner response accepted 仍為 `0/8`。
+- remote dev ready 仍為 `0/8`。
