In remote desktop mode, `run_command` and `invoke_menu` can both call `pathfinder.repeat` with `{}`. Successful panel operations, direct `object.pathfinder.*` commands, and `command.batch` steps (including Actions panel playback) set its history. Repeat applies it to the current selection using current Pathfinder Options. Trap, compound-shape edits, live effects and `action.batch` do not set history.

Type in the design that holds a `%` followed by two digits shows each column's value, with at least the first digit's places before the decimal point and the second digit's places after it. |

+| `text_wrap` | `{ids?, offset?, invert?, release?}` | Area type below the objects (same layer) flows around them. `offset` is in points, from -1000 to 1000 (default 6). An offset outside that range or not a number, or an `invert` or `release` that is not true or false, is an error and changes nothing; `object.textWrap.make` and `object.textWrap.options` refuse the same values. |
 | `undo` / `redo` | `{}` | Many calls that change nothing record no undo step, for example `object.align` with nothing to move, `object.move` by 0 without `copy` and `object.showAll` with nothing hidden. `undo` (`edit.undo`) after such a call undoes the step before it. `inspect_document` lists the undo steps as `history`. `run_command` with `edit.clearHistory` removes every undo and redo step of the active document and returns `{cleared}`, the number of steps removed; the document stays as it is, and the command records no undo step. `run_command` with `edit.newDocumentFromState` and `{index?, created?}` makes a new document holding the art as it was at that state and makes it the active document, and returns `{index, title}`. `index` is a row of the History panel, with 0 the oldest state kept, and an omitted or null `index` uses the current state. An `index` that names no state fails with `no history state N`, one that is not a whole number with `` `index` must be a whole number ``, and either changes nothing. `created` is File Info's created date in Unix seconds or null, and defaults to now. The new document takes the next `Untitled-N` name, is marked unsaved, has nothing selected and has no steps to undo or redo. It is out of symbol, opacity-mask and pattern editing, and the art drawn in a pattern's tile is stored in the pattern, as `object.pattern.done` stores it. The source document and its steps stay as they are, except that typing or a drag in progress is first kept as a step. When a command keeps a drag whose preview Real-time Drawing off had not applied yet (`edit.undo`, `edit.redo`, `edit.clearHistory`, `edit.newDocumentFromState` and the other commands that end a drag first), and applying that preview gives a warning, the command's result carries it as `previewWarning`, and as `warning` too when the command gives no warning of its own; the app's status bar shows `warning`. While the Type tool edits type, `undo` and `redo` put its caret, with no characters selected, at the end of the text the step changed: after the text it puts back or retypes, or where the text it takes out was. A step that changes no characters, such as a formatting change, leaves the caret and the selection where they are. |

   The Character panel menu's Show Font Height Options shows a Set Font Height Reference dropdown under Font Size (`text.setFormat` or `text.setRangeStyle` `{fontHeightReference}`). Each reference shows an icon of the height it measures before its name, in the open list and in the closed field (#6304): a frame around a letter for Em Box, a bar from the baseline to the top of a capital for Cap Height and of a lowercase x for x-Height, and a frame inset in the em square for ICF Box. With Em Box, the default, the font size is the size of the em square; with Cap Height, x-Height or ICF Box, the characters are set at the em size at which the font's OS/2 cap height, its x height or the height of its ideographic character face equals the font size. With a font that has no such value, or one outside 0.1 to 2 em, the size measures the em box. SVG, PDF and legacy `.ai` export and the CSS Properties rules write the em size the characters are drawn at, and DXF export writes 0.7 times that em size as each TEXT entity's height (group 40, the height of its capitals). Behavior reference: [Vary font height](https://web.archive.org/web/20251118174722/https://helpx.adobe.com/illustrator/desktop/design-with-text/edit-format-text/vary-font-height.html).
   The Every-line Composer composes a paragraph whose characters differ in line metrics (type size, font, leading or vertical scale, or an inline graphic taller than the text) in area type of any shape, rows, columns and text wrap included. In a frame that is not a rectangle, or with text wrap, each line it tries is measured where the lines above it put it, across the line's own height, so a taller line gets the room of the narrower part of the frame, or of the span beside a wrap object, that it reaches. When the frame cannot hold all of such a paragraph, the lines it holds are still composed with the whole paragraph, the lines past the frame's end measured as wide as the last line the frame holds (VectorCraft's own rule); they overflow or go on in the next threaded frame, which composes them again. Such a paragraph is broken with the Single-line Composer when the frame has no room for its first line or when the search passes VectorCraft's own limits. The Single-line Composer measures a line's room across the height of its tallest character too: a line that takes in a taller character is placed again and broken again in the room there. Behavior reference: [the help page](https://helpx.adobe.com/illustrator/desktop/design-with-text/edit-format-text/set-hyphenation-and-line-breaks.html), and for text that flows on between threaded objects, [the help page](https://helpx.adobe.com/illustrator/desktop/design-with-text/add-manage-text/create-text-threads-between-objects.html).
   A text wrap object's Offset may be negative as well as positive ([the help page](https://help.adobe.com/archive/en_US/illustrator/cs4/illustrator_cs4_help.pdf#page=307)). A negative Offset (to -1000 pt) shrinks the wrap object by that distance, measured from each edge itself and from the edges of its holes, so lines beside it, above it and below it run that far into it, and an object narrower than twice the distance no longer moves text aside. With Invert Wrap, a negative Offset keeps the text that far inside the object. These are VectorCraft's own rules for the shape of the shrunk object. Text Wrap Options, `object.textWrap.make` and `object.textWrap.options` and the MCP `text_wrap` tool take the negative value, and layout uses it (`crates/text/src/layout/region.rs` tests, `cmd::textwrap::tests::text_wrap_options_negative_offset_reflows_and_round_trips`).
+  `object.textWrap.make`, `object.textWrap.options` and the MCP `text_wrap` tool refuse an Offset outside -1000 to 1000 pt, VectorCraft's own range, or one that is not a number, and an Invert Wrap value that is not true or false, with an error and no change or undo step; an omitted or null value takes the default (`cmd::textwrap::tests::text_wrap_commands_refuse_bad_offsets_and_inverts_without_editing`).
   In area type of a shape other than a rectangle, each line's whole band, ascent to descent, stays inside the frame: where an edge pinches in within the band, the line ends at the narrowest point, and a line runs beside a hole that starts and ends within its band, not across it. In area type of any shape, a line also stays clear of a text wrap object that reaches into any part of its band, and inside an Invert Wrap object over its whole band (`crates/text/src/layout/region.rs` tests).
   In area type whose frame has several contours, a line runs across an edge two contours share only when their edges lie exactly on one line, so a gap between contours keeps lines from crossing it, even a gap one unit in the last place wide near the edge of the canvas; an edge divided by an anchor exactly on it still lets lines cross (`layout::region::separate_slanted_contours_keep_a_four_ulp_gap_near_canvas_limit`, `shared_slanted_edge_still_joins_near_canvas_limit`, `area_type_sets_no_line_across_a_four_ulp_gap_between_slanted_contours`).
   With Invert Wrap and a positive Offset, a line uses all the room the wrap shape grown by the Offset (across and along) holds at every height of its band: beside a notch the Offset fills, the line reaches the grown edge, whatever the band's height, the slope of the notch's sides or the number of anchors on the shape (VectorCraft's own measure). Measuring a wrap shape of many parts (a comb of 500 teeth) takes a few dozen steps per part, not one per pair of parts. The measure stops after a fixed number of steps; a shape that needs more, for example one whose edges cross one another tens of thousands of times, has its band cut into at most 64 pieces instead, which keeps the line inside the grown shape but can leave it shorter than the grown shape allows (`crates/text/src/layout/region.rs` tests).
