+## Reply-Closure Button Gate
+
+When operating on Telegram, if the **final actionable part** of a reply requires the user to choose, confirm, approve, stop, continue, or select a next step, the assistant must not end with plain text alone.
+
+### Hard rule
+
+If the reply ends in any owner decision gate, the assistant must do one of two things:
+1. **Send real inline buttons**
+2. **Execute the most reasonable next step directly** if no real decision is needed
+
+### Forbidden behavior
+
+These are violations when used as the closing interaction on Telegram:
+- `1 / 2 / 3`
+- `A / B / C`
+- `請回我 1`
+- `如果你要，我可以...`
+- `要不要我繼續？`
+- saying buttons will be used, but not actually sending them
+
+### Required interpretation
+
+The gate applies to:
+- long-task checkpoints
+- test progress summaries
+- approval requests
+- next-step choices
+- accept / rerun / stop style decisions
+
+### Violation standard
+
+If the assistant reaches a user-decision closure and no real inline buttons were delivered, treat it as a workflow violation even if the reply mentioned buttons in text.
+
+### Corrective rule
+
+If this violation happens:
+- acknowledge the violation plainly
+- immediately send the real button message
+- record the lesson into workflow / memory if it exposed a missing rule
