+Grid / Table Cell Addressing
+============================
+
+``anchor_locator`` does pairwise spatial relations (target *near* / *below* an
+anchor) but nothing addresses a 2-D grid — "the cell at row 3, column 2" of a
+table. Given the bounding boxes of the cells (from an image or OCR enumeration,
+e.g. ``locate_all_image`` / ``find_text_matches``), this clusters them into rows
+and columns and returns the requested cell's centre.
+
+The clustering and lookup are pure (boxes in, grid / cell out) and fully
+unit-testable; the box enumeration stays the caller's job, so nothing here needs a
+real screen. Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import cluster_grid, locate_cell
+
+    boxes = [(10, 100, 20, 10), (110, 100, 20, 10), (210, 100, 20, 10),
+             (10, 200, 20, 10), (110, 200, 20, 10), (210, 200, 20, 10)]
+
+    locate_cell(boxes, row=1, col=2)
+    # {'found': True, 'center': [220, 205], 'box': [210, 200, 20, 10],
+    #  'row': 1, 'col': 2, 'rows': 2, 'cols': 3}
+
+    cluster_grid(boxes)   # rows top-to-bottom, cells left-to-right
+
+``cluster_grid`` sorts the boxes by centre-y, starts a new row when the gap
+exceeds ``row_tolerance``, and orders each row's cells by centre-x.
+``locate_cell`` returns the centre (ready to click) of the 0-based ``(row, col)``
+cell, or ``{found: False, reason}`` when the index is out of range.
+
+Executor commands
+-----------------
+
+``AC_grid_cell`` takes ``boxes`` (a JSON ``[[x, y, w, h], ...]`` list, e.g. from a
+prior ``AC_locate_all_image`` step) plus ``row`` / ``col`` / ``row_tolerance`` and
+returns the cell dict. It is exposed as the MCP tool ``ac_grid_cell`` and as a
+Script Builder command under **Mouse**.

+表格 / 格線儲存格定位
+====================
+
+``anchor_locator`` 處理成對的空間關係(目標在錨點*附近* / *下方*),但無法定位二維格線——表格中「第 3 列、
+第 2 欄的儲存格」。給定各儲存格的邊界框(來自影像或 OCR 列舉,例如 ``locate_all_image`` / ``find_text_matches``),
+本功能將其分群為列與欄,並回傳所求儲存格的中心。
+
+分群與查詢皆為純函式(框進、格線 / 儲存格出),完全可單元測試;框的列舉仍由呼叫端負責,因此此處不需真實螢幕。
+不匯入 ``PySide6``。
+
+無頭 API
+--------
+
+.. code-block:: python
+
+    from je_auto_control import cluster_grid, locate_cell
+
+    boxes = [(10, 100, 20, 10), (110, 100, 20, 10), (210, 100, 20, 10),
+             (10, 200, 20, 10), (110, 200, 20, 10), (210, 200, 20, 10)]
+
+    locate_cell(boxes, row=1, col=2)
+    # {'found': True, 'center': [220, 205], 'box': [210, 200, 20, 10],
+    #  'row': 1, 'col': 2, 'rows': 2, 'cols': 3}
+
+    cluster_grid(boxes)   # 列由上到下、儲存格由左到右
+
+``cluster_grid`` 依中心 y 排序框,當間距超過 ``row_tolerance`` 時開始新的一列,並將每列的儲存格依中心 x 排序。
+``locate_cell`` 回傳 0 起算 ``(row, col)`` 儲存格的中心(可直接點擊),索引超出範圍時回傳
+``{found: False, reason}``。
+
+執行器命令
+----------
+
+``AC_grid_cell`` 接受 ``boxes``(JSON ``[[x, y, w, h], ...]`` 清單,例如來自前一個 ``AC_locate_all_image`` 步驟)
+以及 ``row`` / ``col`` / ``row_tolerance``,並回傳儲存格 dict。它以 MCP 工具 ``ac_grid_cell`` 以及 Script Builder
+中 **Mouse** 分類下的命令提供。
