+## Contour add-on
+
+Contour is a built-in add-on: it grows or shrinks a copy of a path or shape by a distance, live. Its command is
+`addon.contour.set`; in the desktop app it lives in Object › Plug-ins › Contour and in the Contour Tool (`contour`), which
+the toolbars don't show until it is added from the All Tools drawer (or chosen with `tool.select`); it has no shortcut. A
+floating bar over the selection (the distance, Sharp / Round / Square and Bake) acts through the same commands.
+
+`addon.contour.set {offset, corners?, miterLimit?}` puts a copy of each selected path, shape or compound path directly above
+it with a live Offset Path effect of `offset` points (negative insets), and selects the copies. `corners` is `"sharp"`
+(default), `"round"` or `"square"` (corners cut off flat), `miterLimit` 1 to 500 (4; sharp corners). A selected object that
+already has that effect (a Contour made earlier) has its effect changed instead of getting another, so the same call
+adjusts a Contour. The original is kept, and nothing is baked: `effect.expandAppearance` turns a Contour into plain paths.
+Type, images and groups are left alone; with nothing to offset it says "select paths or shapes". One undo step. Result:
+`{ids, created, updated}`.
+
+The tool (`contour`) drags a distance from the selected shape's edge, outward to grow and inward to shrink: the press
+changes nothing until the pointer moves, a Contour that already stands at a distance continues from it, Shift rounds to
+whole points and Escape cancels. A drag keeps a Contour's own corners and miter limit; a new Contour takes the tool's
+options `corners` and `miterLimit` (`tool.setOption`). A border with a gap is two Contours of one shape (the gap first, so
+it ends up in front), baked with `effect.expandAppearance`, then `object.pathfinder.minusFront`.

 | **Agent automation** | beyond Illustrator | Every command, gesture and dialog is drivable over MCP, the CLI and the control channel; synthetic-input counts, pending events and per-frame control requests are bounded (#1709); what an agent reads and writes on disk can be confined to chosen folders (`--automation-read-root` / `--automation-write-root`, as in PhotoCraft, #832) |
 | **Scrubby numeric fields** | beyond Illustrator | As in Photoshop, dragging a numeric field's label (`W:`, `Opacity:`, the Character panel's icons) left or right steps its value live; one undo step per drag, Escape cancels (#400) |
 | **Align Stroke on live type** | beyond Illustrator | The Stroke panel's Align Stroke works on type's character stroke: inside or outside the glyphs without Create Outlines, the type staying editable (as InDesign does; users have asked Illustrator for it since 2010, e.g. [redd.it/1dwhos6](https://redd.it/1dwhos6)). Canvas, PDF and EPS clip it to its side of the glyphs; SVG keeps the text live and draws the stroke on the glyph outlines (#2294) |
+| **Contour add-on** | beyond Illustrator | Drag away from a selected shape's edge to grow a live copy of it, or toward the inside to shrink it (Shift: whole points); the copy carries a live Offset Path effect so it stays editable, with its own fill and stroke, until Bake (Expand Appearance). A second drag on a selected Contour changes it instead of nesting another; Escape cancels. A floating bar above the selection sets the distance and the corners (Sharp, Round, Square); `addon.contour.set` makes or changes one over MCP and the control channel.

 - **Escape in Selection tool drags:** Escape during a Selection tool move or Alt-drag copy, a bounding-box scale or rotation, a marquee, or a corner widget, pie widget or bracket drag cancels it: the art returns to its state at the press, no copy is left, no undo step is added, the release does nothing, and the tool stays chosen. This is VectorCraft's own behavior. Regression tests: `escape_cancels_*` in `select/tests.rs` and `pie.rs`, and `escape_cancels_a_selection_tool_move_copy_scale_or_rotation` in `tests/selectescape.rs`.
 - **Global Edit: Shift-click leaves a match out:** while Global Edit is on, a Shift-click with the Selection tool on a highlighted match, or on an object inside a matched group, leaves that match out (`select.globalEditExclude`): it is no longer highlighted and later edits leave it as it is; the object the edit started from stays, and Global Edit ends when fewer than two matches are left ([Update assets quickly with Global Edit](https://helpx.adobe.com/ph_fil/illustrator/how-to/global-editing-sensei.html)). Regression tests: `a_shift_click_*`, `an_object_left_out_*`, `a_group_left_out_*` and `leaving_out_all_but_one_*` in `crates/engine/src/tests/globaledit.rs`.
 - **Global Edit Options in the Control bar:** while Select › Start Global Edit can run, the Control bar shows a Global Edit Options dropdown that opens the same options as the Properties panel's (Match: Appearance, Size; On Artboards; Include Objects On Canvas; Result(s)); both set the same options. The dropdown is off while Global Edit is on; it sits after Recolor Artwork, ahead of the X/Y/W/H fields ([Edit similar objects globally](https://helpx.adobe.com/illustrator/desktop/manage-objects/edit-objects/edit-similar-objects.html)). Regression test: `the_control_bar_shows_the_global_edit_options` in `crates/ui-egui/src/chrome/tests.rs`.
+- **Global Edit's enabled check on large paths:** the check that decides whether Select › Start Global Edit can run on the selected path, compound path or symbol instance (which the Control bar makes every frame) measures the box of its anchors and handles instead of building and normalizing a copy of every anchor, with the same answer. On a 200,000-anchor path the check takes 0.7 ms instead of 2.2 to 3.0 ms. Regression tests: `support_*` in `crates/engine/src/cmd/globaledit.rs`.
 - **Control bar's inline X, Y, W and H fields fit the bar:** the Control bar shows the inline X, Y, W and H fields only when all four, their labels as drawn in the current language and the W/H link fit inside the bar's margin; otherwise it shows the Transform link alone. This is VectorCraft's own layout rule. Regression test: `the_control_bar_shows_the_inline_transform_fields_only_when_they_fit` in `crates/ui-egui/src/chrome/tests.rs`.
 - **Pattern-only backquote drags:** With Selection move, bounding-box scale or rotate, or the Rotate, Reflect, Scale or Shear tool, backquote held at mouse release applies the drag matrix to selected pattern paint while object geometry stays in place. The key may be pressed after mouse press; if released before the mouse button, the drag commits as an ordinary transform. Objects without pattern paint stay still; stroke-only patterns and patterned objects in mixed selections take the same matrix. Regression tests: `backquote_move_uses_release_state_and_one_commit` and `backquote_box_scale_and_rotate_use_pattern_matrix_at_release` in `select/tests.rs`, `backquote_drag_previews_and_commits_pattern_only_for_each_transform_tool` in `xform/transform.rs`, `selection_backquote_drag_changes_pattern_fill_and_stroke_without_moving_mixed_art` and `selection_backquote_drag_changes_stroke_only_pattern` in `tests/pattern.rs`, `egui_backtick_drag_uses_key_state_at_release` in `canvas/tests.rs`, and `synthetic_pointer_backquote_keeps_solid_object_in_place` in `control/tests.rs`. Scores and hours unchanged.
 - **Existing-guide Escape cancellation (G1):** Escape clears a pending guide press or drag through Selection and Direct/Group Selection, cancelling a begun preview. Eight app-input regressions cover both axes, move/copy, temporary selection-tool borrowing from idle Pen, preselected-guide document/interaction-start selection and Undo/Redo/saved-state preservation, later on-canvas motion/release, Shift-press cancellation, and ordinary-release/Enter/idle controls. Historical focused checks on `8ab574b7` recorded five expected RED failures with three passing controls, then all eight GREEN tests and the Direct Selection Escape control passed. All nine also passed in current full CI. A full CI retry on the five-unit combined source at `a0671777` passed all seven stages with 6,613 test outcomes on 2026-10-14. An earlier full-CI run on the identical source panicked in the randomized `ai_mutated_save_never_panics` test; the cause remains unresolved. This five-fix batch does not claim to repair that failure. The original 1280×960 headless app capture from `b076025a` was reviewed for one vertical Selection guide after Escape; source review found its scene unchanged on `a0671777`. Scores and hours unchanged.
