+- 因此已再補一條 skill 規則：`Telegram interaction guard`，禁止 governed long-task flow 在 Telegram 上用純文字選單收尾；若需要選擇，必須改用 inline buttons，否則直接執行最合理下一步。

+### Telegram interaction guard
+
+When operating under long-task governance on Telegram:
+- do not end checkpoints, test progress, or next-step decisions with plain-text menus like `1 / 2 / 3` or `A / B / C`
+- if a choice is genuinely required, use Telegram inline buttons
+- if no real choice is needed, execute the most reasonable next step directly
+- if the assistant accidentally emits a plain-text choice menu, treat that as a workflow violation and convert the lesson into a permanent rule
+
+This prevents governed long-task flows from degrading back into ambiguous text-only decision gates.
