 ## What's new (2026-06-26)
 
+### Template-Free Element Proposal (Pixels to Elements)
+
+Get a clean numbered element list straight from the screen when there's no accessibility tree. Full reference: [`docs/source/Eng/doc/new_features/v220_features_doc.rst`](docs/source/Eng/doc/new_features/v220_features_doc.rst).

+- **`propose_elements` / `tag_kinds`** (`AC_propose_elements`, `AC_tag_kinds`): Set-of-Marks, `observation` and the grounding helpers all assume you already have element boxes — but a game, a custom-drawn app or a remote desktop has no accessibility tree. `propose_elements` builds that top-of-funnel list from pixels: detect widget boxes (closed-edge blobs via Canny + morphology + `connected_boxes`) and text boxes (`text_regions.find_text_regions`), fuse them — the `element_parse` `ocr > icon` priority *is* the "drop widget-that-is-really-text" cross-check — and return them in reading order, each tagged `text` or `widget`. `tag_kinds` is the pure labeller. cv2 imported lazily; the labeller is fully testable. Seventh and final feature of the ROUND-15 perception lane. No `PySide6`.
+
+### Classify a Widget from Its Pixel Shape
+
+Tell a checkbox from a radio button from a text field — from pixels, no model. Full reference: [`docs/source/Eng/doc/new_features/v219_features_doc.rst`](docs/source/Eng/doc/new_features/v219_features_doc.rst).

+- **`classify_widget` / `box_features` / `classify_icon`** (`AC_classify_widget`, `AC_classify_icon`): Set-of-Marks and element proposers return *boxes* but not *what each box is*; `form_fields.checkbox_state` reads a box already known to be a checkbox — the gap is the typing step before it. `box_features` extracts `{aspect, fill, edge_density, circularity}` for a box; `classify_widget` is the pure heuristic classifier (round→radio, wide-rounded→toggle, square-sparse→checkbox, wide-hollow→text_field, wide-filled→button, else icon); `classify_icon` composes them. The classifier is pure and fully testable; cv2/numpy imported lazily so the module stays importable. Sixth feature of the ROUND-15 perception lane. No `PySide6`.
+
+### Localize a Change to the Elements That Changed
+
+Turn a raw screen diff into "element 3 changed" by scoring a list of element boxes. Full reference: [`docs/source/Eng/doc/new_features/v218_features_doc.rst`](docs/source/Eng/doc/new_features/v218_features_doc.rst).
+
+- **`localize_changes` / `rank_changes`** (`AC_localize_changes`, `AC_rank_changes`): existing diffs answer *where* pixels changed (`motion_regions`, `perceptual_diff`, `ssim_changed_regions` → raw pixel regions) or which *accessibility* elements differ (`element_diff`, needs metadata) — but not "given a frame diff **and a list of element boxes**, which of *those* changed?". `localize_changes` diffs a reference against the current screen and scores each supplied element box by its mean per-pixel change; `rank_changes` is the pure ranker that flags `changed` (score ≥ `threshold`) and sorts most-changed first. Pairs with `set_of_marks`/accessibility boxes to give a per-element "what changed" feedback signal after a click. cv2/numpy imported lazily; ranking is pure and fully testable.

+Localize a Change to the Elements That Changed
+==============================================
+
+The existing diffs answer "*where* did pixels change" (``motion_regions``,
+``perceptual_diff``, ``ssim_changed_regions`` return raw pixel regions) or "which
+*accessibility* elements differ" (``element_diff``, needs a11y metadata). The
+missing middle is: given a frame diff **and a list of element boxes**, which of
+*those* elements changed? ``change_localize`` scores each supplied box by how
+much it changed and ranks them.
+
+* :func:`rank_changes` — pure: take ``[{box, score}]`` and mark each box
+  ``changed`` (score at or above ``threshold``), sorted most-changed first.
+* :func:`localize_changes` — diff a reference against the current screen, score
+  each element box by its mean pixel change, and rank them.
+
+``cv2`` / ``numpy`` are imported lazily (the module stays importable without
+them) and the loaders reuse :mod:`visual_match`. The ranking is pure and fully
+testable. Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import localize_changes, rank_changes, mark_elements
+
+    boxes = [mark["bbox"] for mark in mark_elements(elements)]
+
+    # After an action, which of those elements actually changed?
+    changed = localize_changes("before.png", boxes, current="after.png")
+    for entry in changed:
+        if entry["changed"]:
+            print("element changed:", entry["box"], entry["score"])
+
+    # Or rank pre-computed scores yourself:
+    rank_changes([{"box": [0, 0, 40, 20], "score": 0.6}], threshold=0.1)
+
+``localize_changes`` returns ``[{box, score, changed}]`` sorted most-changed
+first, where ``score`` is the box's mean per-pixel change (0..1). It pairs with
+``set_of_marks`` / accessibility element boxes to turn a raw screen diff into a
+per-element "what changed" signal — an agent feedback channel after a click.

+Classify a Widget from Its Pixel Shape
+======================================
+
+Set-of-Marks and element proposers hand back *boxes*, but not *what each box is*.
+``form_fields.checkbox_state`` already reads a box known to be a checkbox; the
+gap is the typing step before it — is this box a checkbox, a radio button, a push
+button, a text field or a toggle? ``icon_classify`` answers that from cheap
+geometric features (no model).
+
+* :func:`box_features` — extract ``{aspect, fill, edge_density, circularity}``
+  for a box region (the objective measurements).
+* :func:`classify_widget` — pure: map a feature dict to a widget type by
+  documented heuristics.
+* :func:`classify_icon` — compose the two: a box to ``{type, features}``.
+
+``classify_widget`` is pure and fully testable; ``box_features`` imports cv2 /
+numpy lazily (the module stays importable without them) and reuses
+:func:`visual_match._to_gray`. Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import classify_icon, classify_widget
+
+    # From a screenshot + a box:
+    classify_icon("dialog.png", [120, 80, 16, 16])
+    # {'type': 'checkbox', 'features': {'aspect': 1.0, 'fill': 0.12, ...}}
+
+    # From features you already have:
+    classify_widget({"aspect": 1.0, "circularity": 0.9, "fill": 0.4})  # 'radio'
+
+The heuristics: a round box (aspect ≈ 1, high circularity) is a ``radio``; a wide
+rounded box is a ``toggle``; a near-square sparse box is a ``checkbox``; a wide
+hollow box is a ``text_field``; a wide filled box is a ``button``; anything else
+is an ``icon``. Tune by reading ``features`` and applying your own rules where
+the defaults misfire — the measurements are the durable part.
+
+Executor commands
+-----------------
+
+``AC_classify_widget`` (``features`` JSON object → ``{type}``, pure) and
+``AC_classify_icon`` (``source`` image + ``box`` ``[x, y, w, h]`` →

+Template-Free Element Proposal (Pixels to Elements)
+===================================================
+
+Set-of-Marks, ``observation`` and the grounding helpers all assume you already
+have a list of element boxes — but on a screen the framework doesn't model
+(a game, a custom-drawn app, a remote desktop) there is no accessibility tree to
+provide one. ``element_proposal`` builds that top-of-funnel list from pixels:
+detect candidate *widget* boxes (closed-edge blobs) and *text* boxes
+(:func:`text_regions.find_text_regions`), fuse them — dropping widget boxes that
+are really just text — and return them in reading order, each tagged ``text`` or
+``widget``.
+
+* :func:`propose_elements` — the full pixel-to-elements pipeline.
+* :func:`tag_kinds` — pure: label fused boxes ``text`` / ``widget`` by source and
+  keep their reading-order ``index``.
+
+The fusion / cross-check / ordering reuse :mod:`element_parse` — the ``ocr`` >
+``icon`` source priority *is* the "drop widget-that-is-really-text" check — and
+the text detection reuses :mod:`text_regions`. ``cv2`` is imported lazily so the
+module stays importable; :func:`tag_kinds` is pure and fully testable. Imports no
+``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import propose_elements, mark_elements
+
+    # No accessibility tree? Propose elements straight from the screen:
+    elements = propose_elements(min_area=120)
+    # [{'box': [x, y, w, h], 'kind': 'widget', 'index': 0}, ...]
+
+    # Feed them to Set-of-Marks like any other element list:
+    marks = mark_elements(elements)
+
+``propose_elements`` returns ``[{box, kind, index}]`` in reading order, where
+``kind`` is ``text`` or ``widget``. It is the missing top-of-funnel for the
+agent stack on un-modelled UIs: pixels in, a clean numbered element list out,
+ready for marking, observation or grounding. Tune ``min_area`` for the smallest
+control you care about and ``iou_threshold`` for how aggressively overlapping
+text and widget boxes are merged.
+
+Executor commands
+-----------------
+
+``AC_propose_elements`` (``region`` ``[x, y, w, h]`` / ``min_area`` /
+``iou_threshold`` → ``{elements}``) runs the full pipeline on the screen, and
+``AC_tag_kinds`` (``elements`` JSON list → ``{elements}``, pure) labels a
+pre-fused list. They are the matching read-only ``ac_*`` MCP tools and Script
+Builder commands under **Image**.
