+Pre-Match Settle Gating + Match Persistence
+===========================================
+
+Matching mid-animation is a top flakiness source: the spinner is still spinning, a transition
+is half-done, and the matcher fires on a transient. ``smart_waits.wait_until_screen_stable``
+gates a *live polling loop* and returns a boolean — it cannot score stability on an *injectable*
+sequence of frames, nor tell you whether a *match* held steady across them. ``match_stability``
+adds both, on injected frames so it is unit-testable: ``region_stability`` scores how settled a
+frame sequence is (consecutive-frame SSIM), and ``match_persistence`` checks that a template's
+hit holds at the same place across the frames (low jitter), not just in one lucky frame.
+
+It reuses ``ssim.ssim_compare``, ``visual_match.match_template`` and
+``grounding_consensus.consensus_point`` — no new matching code. The frames are injectable
+(ndarray / path / PIL). Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import region_stability, match_persistence
+
+    frames = [grab(), grab(), grab()]   # a few snapshots of the same region
+    if region_stability(frames, settle_threshold=0.99)["stable"]:
+        do_the_match()
+
+    result = match_persistence("button.png", frames, min_score=0.8, agree_px=8)
+    if result["persisted"]:
+        print("steady hit, jitter", result["jitter"])
+
+``region_stability`` returns ``{stable, mean_ssim, min_ssim}`` — ``stable`` when the lowest
+consecutive-frame SSIM clears ``settle_threshold``. ``match_persistence`` returns
+``{persisted, n_hits, jitter}`` — ``persisted`` when the template is found in *every* frame and
+the hit centres agree within ``agree_px`` (``jitter`` is their spread; 0 = rock steady).
+
+Executor commands
+-----------------
+
+``AC_region_stability`` (``frames`` / ``settle_threshold`` → ``{stable, mean_ssim, min_ssim}``)
+and ``AC_match_persistence`` (``template`` / ``frames`` / ``min_score`` / ``agree_px`` →
+``{persisted, n_hits, jitter}``). They are exposed as the MCP tools ``ac_region_stability`` /
+``ac_match_persistence`` (read-only) and as the Script Builder commands **Region Stability
+(frames)** / **Match Persistence (frames)** under **Image**.

+比對前安定閘 + 命中穩定性
+==========================
+
+在動畫進行中比對是主要的不穩定來源:轉圈圖示還在轉、轉場做到一半,比對器命中暫態。
+``smart_waits.wait_until_screen_stable`` 閘控*即時輪詢迴圈*並回傳布林——它無法對*可注入*的
+幀序列評分穩定度,也無法告訴你某個*命中*是否跨幀維持。``match_stability`` 補上兩者,且作用於
+注入幀因此可單元測試:``region_stability`` 以相鄰幀 SSIM 評分幀序列的安定度,``match_persistence``
+檢查某 template 的命中是否跨幀維持在同一處(jitter 小),而非只在某一幸運幀。
+
+本功能重用 ``ssim.ssim_compare``、``visual_match.match_template`` 與
+``grounding_consensus.consensus_point``——不新增比對程式。幀可注入(ndarray / 路徑 / PIL)。
+不匯入 ``PySide6``。
+
+無頭 API
+--------
+
+.. code-block:: python
+
+    from je_auto_control import region_stability, match_persistence
+
+    frames = [grab(), grab(), grab()]   # 同一區域的幾張快照
+    if region_stability(frames, settle_threshold=0.99)["stable"]:
+        do_the_match()
+
+    result = match_persistence("button.png", frames, min_score=0.8, agree_px=8)
+    if result["persisted"]:
+        print("穩定命中, jitter", result["jitter"])
+
+``region_stability`` 回傳 ``{stable, mean_ssim, min_ssim}``——當最低相鄰幀 SSIM 超過
+``settle_threshold`` 時 ``stable``。``match_persistence`` 回傳 ``{persisted, n_hits, jitter}``
+——當 template 在*每一*幀都找到且命中中心於 ``agree_px`` 內一致時 ``persisted``(``jitter``
+為其離散度;0 = 穩如磐石)。
+
+執行器指令
+----------
+
+``AC_region_stability``(``frames`` / ``settle_threshold`` → ``{stable, mean_ssim, min_ssim}``)
+與 ``AC_match_persistence``(``template`` / ``frames`` / ``min_score`` / ``agree_px`` →
+``{persisted, n_hits, jitter}``)。兩者以 MCP 工具 ``ac_region_stability`` /
+``ac_match_persistence``(唯讀)及 Script Builder 指令 **Region Stability (frames)** /
+**Match Persistence (frames)**(位於 **Image** 分類下)形式提供。
