The tool's `format` enum and `document.formats` list them, generated from the engine's format table. When `format` is omitted, it comes from the path's extension. PDF and `.ai` write one page per artboard: all of them, or `artboard` (0-based) / `range` (`"1-3, 5"`, 1-based). SVG and SVGZ write one file per chosen artboard. EPS writes one file of the visible art; with `artboard`, `range`, `options.artboards` or `options: {"useArtboards": true}` it writes one file per chosen artboard, after a central file of the visible art when there are two or more, and `useArtboards: false` keeps the one file. Rasters, DXF, EMF and WMF write one artboard, or one file per chosen artboard with `options: {"useArtboards": true}`. Rasters also take `options: {"rect": [x, y, width, height]}` (page points, y down): that area of the page at the given `ppi`/`scale`, without an artboard and without changing the document; it is refused with `artboard`, `artboards`, `range` or `useArtboards`, with a non-positive or non-finite size, and for non-raster formats. `options` carries more format options (e.g. `{"quality": 80}` for JPEG). `selection: true` exports the selected objects cropped to their bounds (the reply adds their `bounds`, and reports `format` and the encoder's `warnings` as a whole-document export does); `outlineText: true` writes SVG text as paths. Template layers are left out, live effects are kept, and exporting `vectorcraft` never changes the document's path. Without `path` the bytes come back as `dataBase64`. Both backends run the same `document.export` call. |
 | `add_text` | `{text, x?, y?, width?, height?, fit?, fitMinPercent?, path?, mode?, pathEffect?, size?, font?, color?, justify?, vertical?}` | Point type at (x, y) (`justify`: `left`, `center` or `right` starts, centres or ends each line on x); area type with `width`/`height` (`fit`: `none`, `autoHeight`, `shrinkText`, as `text.areaOptions`); or `path` + `mode` (`area`/`onPath`) to flow text in or along a path, with `pathEffect` (`rainbow`, `skew`, `3dRibbon`, `stairStep`, `gravity`); `justify` (also `auto`, `justifyAll`) aligns the paragraphs of every kind, as `text.setStyle` does later. `vertical: true` uses the existing vertical writing mode for every kind (default `false`, horizontal). Returns `{id}`, with `overflow: true` when the text doesn't fit its frame or path. |
 | `apply_effect` | `{effect?, params?, ids?}` | Appends a live effect. Without `effect`, returns the effect catalogue with parameters and defaults. |
-| `pathfinder` | `{operation, ids?}` | `unite`, `minusFront`, `intersect`, `exclude`, `divide`, `trim`, `merge`, `crop`, `outline`, `minusBack`. For a live version, apply the `pathfinder.*` effect to a group (`effect.apply` groups several loose selected objects first). |
+| `pathfinder` | `{operation, ids?}` | `unite`, `minusFront`, `intersect`, `exclude`, `divide`, `trim`, `merge`, `crop`, `outline`, `minusBack`. For a live version, apply the `pathfinder.*` effect to a group (`effect.apply` groups several loose selected objects first). 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. With no history it returns "no Pathfinder operation applied yet". |
 | `transform` | `{ids?, dx?, dy?, rotate?, scale?, scaleX?, scaleY?, reflect?, shear?, origin?, copy?}` | Runs move, rotate, scale, reflect, shear in that order. With `copy`, the first step duplicates. |
 | `create_graph` | `{type?, x, y, width, height, csv? \| series?, categories?, rows?}` | The nine Illustrator graph types: column, stacked column, bar, stacked bar, line, area, scatter, pie and radar. An empty CSV cell or a `null` in `rows` is a blank value; a number in straight quotes is a label. Edit later with `graph.setData` / `graph.setType` via `run_command`. `graph.column {design, columnType: vertical\|uniform\|repeating\|sliding, each, fractions: chop\|scale}` draws the columns or bars of the series picked with Group Selection (or `seriesIndexes`, or all of them) with a graph design saved by `graph.design`; with no `design` it returns the series' current design and options. 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. |

   - Extrude & Bevel, Inflate and Rotate (Effect › 3D and Materials): live effects in the `three-d` crate with depth, twist, taper, solid or hollow caps, five original bevel shapes (width, height, repeat, spacing, inside, both sides), Inflate's volume, both sides, twist, taper and cap, Rotate's turned fills and strokes, Position presets, the rotation and light gizmos, SVG/PDF vector output and Expand Appearance; one 3D effect per object; covered by geometry, effect, canvas-versus-export, command and dialog tests ([three-d.md](three-d.md)).
   - Initial live Revolve (#605, #846): a portable geometry and shading crate (`three-d`), editable path and compound profiles, compact options with artboard rotation and light gizmos, SVG/PDF vector output and Expand Appearance that can trim covered faces. Open ends have continuous caps by default, shading is smooth with one to ten colored lights, and intersecting surfaces' visibility is approximate ([revolve.md](revolve.md)).
   - Live effects with previewing dialogs: Distort & Transform, Path, Convert to Shape, 15 Warp styles, Round Corners, Scribble, Effect → Pathfinder (all 10 operations, live on groups; several loose objects are grouped first, in one undo step), Color Adjustments (Brightness/Contrast, Curves, Levels, Hue/Saturation, Shift to Color, Temperature/Tint, on vectors, live type and embedded images), and raster drop shadow, glows and feather. SVG and PDF export keep live effects (geometry baked; SVG raster effects as filters). Zig Zag spaces its ridges evenly along each segment, so lines and curves get a regular wave in Corner and Smooth (#1558). Warp › Arc (the effect and Envelope › Make with Warp) bends in the object's real proportions: a circular arc with concentric edges and no fold-over at 100%, so Arc on art that isn't square draws differently from before (#1581, fixes #1578). `effect.apply` and `effect.setParams` give an error for a misspelt or wrongly typed effect parameter instead of running the effect with its default (#1623, #1592). Roughen with Smooth keeps turn-backs smooth instead of making cusps that draw as spikes (#1646, #1643). Scribble draws one zig-zag per region, with no lines across holes and notches; convex shapes are unchanged (#1651, #1648). On the canvas, in Expand Appearance and in exports, Effect → Pathfinder uses the glyph outlines of type in the group, and results painted like the type keep its opacity and blend mode.
+  - Cmd/Ctrl+4 (`pathfinder.repeat`) repeats the last successful Pathfinder panel operation, direct `object.pathfinder.*` command or `command.batch` step (including Actions playback) on the current selection; the panel menu names it. `action.batch`, Trap, compound-shape edits and live effects do not set history.

   - Pathfinder Options ([Pathfinder panel overview](https://helpx.adobe.com/illustrator/desktop/manage-objects/reshape-transform-objects/pathfinder-panel-overview.html)): the panel menu's Pathfinder Options… sets Precision (0.001–10 pt: results refit to within it, thinner pieces dropped), Remove Redundant Points and Divide and Outline Will Remove Unpainted Artwork (`object.pathfinder.options`, kept in the preferences) for every Shape Mode and Pathfinder operation; the defaults keep the earlier output (`pathops` `precision_drops_pieces_thinner_than_it`, engine `tests_pathops` Pathfinder Options tests, `panels::pathfinder` dialog test).
   - Pathfinder › Trap ([trapping](https://helpx.adobe.com/illustrator/using/trapping.html), [Pathfinder panel](https://helpx.adobe.com/illustrator/using/pathfinder-panel-overview.html)): the Pathfinder panel menu's Trap… (`object.pathfinder.trap`) and Effect › Pathfinder › Trap… (`pathfinder.trap`, live on groups) add, where two objects' visible areas of different solid colours meet, a strip of the darker one's area along the edge, filled with the lighter colour at the Tint Reduction percentage and set to overprint (Reverse Traps: the darker colour spreads instead, but not a rich black); Thickness 0.01–5000 pt across vertical edges, Height/Width scales it across horizontal ones, Traps with Process Color paints a swatch colour's trap with its CMYK equivalent; the effect also has Precision and Remove Redundant Points. The panel's Trap is one undo step and groups the traps above the topmost selected object, selected; with no adjoining edges of different colours it says so and changes nothing. Tests: `crates/pathops/src/trap.rs`, `crates/effects/src/trap.rs`, `group::tests::trap_effect_adds_an_overprinting_strip_above_the_members`, `crates/engine/src/tests/trap.rs`, `panels::pathfinder::tests::trap_opens_its_options_and_ok_traps_the_selection`.

With members selected (Direct Selection, Layers panel, isolation mode) a Shape Mode button sets theirs (`object.compoundShape.setMode`) and is lit for the mode they share; paint given to a member goes to the compound shape. Release Compound Shape gives the members back as they were (`object.compoundShape.release`); Expand Compound Shape and the panel's Expand button turn it into the path or compound path of its area (`object.compoundShape.expand`). Shape Modes and Pathfinders take a compound shape as its area. Saved files keep it (`compound_shape`, `shape_mode`; an unknown mode reads as Add). Tests: `crates/engine/src/tests/compound_shape.rs`, `group::tests::compound_shapes_draw_the_area_their_shape_modes_make`, `group::tests::nested_compound_shapes_take_part_as_their_area`, `panels::pathfinder::tests::compound_shape_items_follow_the_selection`, the `CompoundShape` op of the property-test strategies. Not yet: blends, envelopes and warps as members, the question marks on mixed member modes, hit-testing by the area (a click hits the members).
