+Action-Effect Classification (Did My Click Do Anything?)
+========================================================
+
+After an agent clicks, the crucial question is "did that do anything, and was it the *right*
+thing?" — but nothing answered it on the *first* step. ``screen_state.diff_snapshots`` and
+``element_diff`` report what changed but never tie the change back to the action;
+``loop_guard`` only flags a no-op after the same digest repeats N times (so the agent loops
+2–8 times first); ``actionability`` is purely a *pre*-action gate. ``action_effect`` closes the
+loop: it diffs the before/after observation and, given the action's target point, classifies
+the result so an agent can react immediately.
+
+The verdict is one of ``no_op`` (nothing changed), ``changed_near_target`` (the change happened
+where we acted — a button depressed), ``changed_elsewhere`` (a surprise dialog popped somewhere
+else), or ``changed`` (something changed but the action carried no point to attribute to).
+
+Pure-stdlib over element dicts + the action record; reuses ``element_diff.match_elements`` for
+the overlap join and ``observation_delta``'s field-change check. Fully deterministic and
+unit-testable with no device. Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import classify_effect, effect_near_point, is_no_op
+
+    verdict = classify_effect(before_elements, after_elements,
+                              {"type": "click", "x": 480, "y": 260})
+    if verdict.effect == "no_op":
+        retry_or_repair()

+        handle_unexpected_dialog()
+
+    if is_no_op(before_elements, after_elements):
+        ...
+
+``classify_effect`` returns an ``EffectVerdict`` (``effect`` / ``changed_near_target`` /
+``changed_count`` / ``changed_centers`` / ``reason``). ``effect_near_point`` answers whether any
+change landed within ``radius`` of an arbitrary point; ``is_no_op`` is the boolean shortcut.
+
+Executor commands
+-----------------
+
+``AC_classify_effect`` (``before`` / ``after`` / ``action`` / ``radius`` →
+``{effect, changed_near_target, changed_count, changed_centers, reason}``) and
+``AC_effect_near_point`` (``before`` / ``after`` / ``point`` / ``radius`` → ``{near}``). They
+are exposed as the MCP tools ``ac_classify_effect`` / ``ac_effect_near_point`` (read-only) and
+as the Script Builder commands **Classify Action Effect** / **Effect Near Point?** under
+**Native UI**.

+動作效果分類(我的點擊有沒有效果?)
+====================================
+
+代理點擊後最關鍵的問題是「這有沒有效果,而且是*正確的*效果嗎?」——但在*第一步*就回答這個
+問題的功能並不存在。``screen_state.diff_snapshots`` 與 ``element_diff`` 回報變了什麼,卻從不
+把變化歸因回該動作;``loop_guard`` 只在相同摘要重複 N 次後才標記 no-op(因此代理會先空轉
+2–8 次);``actionability`` 純粹是*動作前*的閘門。``action_effect`` 補上這個迴圈:比對前後
+觀測,並依動作的目標點分類結果,讓代理能立即反應。
+
+判定為下列之一:``no_op``(無變化)、``changed_near_target``(變化發生在我們動作之處——按鈕被
+按下)、``changed_elsewhere``(別處彈出意外對話框)、或 ``changed``(有變化但動作沒有可歸因的
+座標點)。
+
+純標準函式庫,作用於元素字典 + 動作記錄;重用 ``element_diff.match_elements`` 做重疊配對與
+``observation_delta`` 的欄位變更檢查。完全確定性、可在無裝置下單元測試。不匯入 ``PySide6``。
