* M8: grid auto-placement on an occupancy bitmap (#1083)
Grid placement tested every cell of a child's span at every position it tried. The taken cells are now a bitmap: spans are checked a 64-bit word at a time, the search jumps past the blocking cell, a row's search ORs the span's rows once, and a column-anchored child looks on from where the last one with the same column and spans found room. Placements are unchanged (checked against the old search on random grids); a crafted 1000 x 1000 grid takes 0.3 ms instead of 192 ms.
* M8: grid occupancy stores rows only once a cell in them is taken
An empty or sparse grid no longer allocates the whole bitmap up front (CodeRabbit on #1593).

A double-click with the pen drew on: its second press added a point on the last one, and a double-click meant to edit a layer drew a stray vector on it. A press on the last anchor now adds nothing; a double-click ends the path (or, when it only started one, edits the layer under it) and Enter ends the path, both going on in vector edit mode with the Move tool. In edit mode the pen's Enter and double-click take the Move tool, the double-click taking back what its first press began. Escape still keeps the pen (#760).
Desktop recovery copies saved DocState::doc, which is the version shown while a version (or a live text preview) is previewed, so a crash during a preview brought the old version back as the unsaved file. What a recovery copy holds is now one shared helper, branches::recovery_copy: the document itself (document_itself(), the same document the unsaved-changes check compares), its history and its branches. The desktop copies and the browser's (#1580) both use it.
* M6: FigJam .jam files open like .fig files (#1342)
A .jam is the same archive as a .fig (its canvas header reads fig-jam.), which the .fig reader already took; File > Open and its filter, drag and drop, file.import and the command line now take .jam too, and the home screen shows its thumbnail. FigJam layers come in as the .fig reader makes them (stickies and shapes with text as frames with their generated layers, other FigJam layers as frames or vectors with a note, unknown types left out with a note). Tests use a synthetic fig-jam. canvas and a .jam made from our own export.
* M12: a FigJam .jam file opens as a board (#1342)
The .fig reader marks a canvas with FigJam's fig-jam. header as FileKind::Board, so a .jam opens with the board toolbar, the dot grid and the board panels and saves as a board; a .fig stays a design file, and importing a .jam into an open file leaves its kind alone. Its objects stay ordinary layers (frames and vectors with the existing import notes). Builds on the .jam opening branch (#1586).
A search offered engine commands that need parameters the palette can't give, such as image.place (Place image, needing data or path), which failed with Invalid parameters and sat above the menu's Place image... row with the same label. A search now leaves out a command no menu lists when its params doc names a parameter without ? (figcraft_engine::cmd::needs_params, worked out once per command), and a row no menu item gives whose label reads like a menu item's. Place image runs the menu item, which opens the file dialog.
Someone who joins with a comment link (or its join code) sees the file live and adds, replies to, reacts to and resolves comment threads, but can't change the design: their app refuses other edits and the server accepts a comment link's batch only when every change in it touches comment threads. Sharing online makes a comment link and code beside the edit and view ones; the Share popover offers Can edit, Can comment and Can view, and the commenter's toolbar shows a Can comment badge with Move, Hand and Comment.
Backward compatible: clients announce the comments word; one that doesn't is welcomed with a comment link as a viewer and gets comment links listed as view links, a level this build doesn't know reads as view, and an older server that can't make a comment link leaves the share without one.
With pref.scrollWheelZoom on, a mouse wheel zooms the canvas about the pointer and Cmd/Ctrl+wheel scrolls; Shift+wheel still scrolls sideways, and trackpads, pinches and touch screens are unchanged. A wheel is told from a trackpad by the device macOS reports, elsewhere by line versus pixel steps.
comment.list takes mentions (a name, any case): only threads where a message, the first or a reply, @mentions it, by the same parser the thread view highlights with and each message's mentions reports; combined with the other filters.
wasm32 can't catch a panic, so the command and frame guards do nothing in the browser and a panic ended the page with its unsaved changes. The page now follows its files with unsaved changes after every frame; its panic hook writes them to local storage as .figcraft copies (as many as fit) and says on the page that it stopped. The next page opens them again as unsaved files: file.recover also takes the copy as base64 data. The recovery-copy helpers move from the desktop app into figcraft_engine::branches so both share them.
Each sweep takes at most 250 000 segments and 2 million possible crossings (pairs of segments whose bounds overlap, counted in O(n log n)), and a fold at most 4 million segments swept over its steps; past them the operation is refused with PathOpsError::TooComplex before it runs. A boolean group past the caps draws without its result, with a warning once, and the refusal is cached; vector.flatten refuses it instead of dropping it.
clap derive types replace the hand-written parser: typed values, usage
errors (exit 2) before any work, help from the same definitions.
Syntax changes: a repeated option is a usage error (was: last wins; the
automation roots still repeat); a value starting with `-` needs `=`; a
positional starting with `-` needs `--`; `--o` and the `version`
subcommand are gone (`--version` stays); `<sub> --help` prints that
subcommand's help; usage errors are clap's text; `--format` is checked
before the file is opened.
Properties were listed by name, so a rename moved one. Components now keep prop_order (the names as they were made; a rename keeps the place) and every listing follows it. Make slot opens a name field under the frame's Slot row; Enter makes the slot, Escape cancels, a taken name keeps the field open.
The web transport implements LiveLink::publish and the hosting and sharing background requests over the page's WebSocket. Managing connections run as exchanges (exchange.rs) in the browser client's driver; the requests and what their answers mean are shared with the desktop transport (requests.rs). The Share popover offers online sharing in the browser (no local network), and Publish to server opens there. Fixes#917.
Where the browser lists them (window.queryLocalFonts, Chromium), the font menu offers Use fonts installed on this computer; the fonts join the font database by name and each style's bytes are read only when text uses it, then auto-sizing text refits. Rust only (js-sys/web-sys). Fixes#1051.
The SVG parser reads neither, so fills came in black and strokes were dropped without a note. They are resolved before parsing: color(srgb|display-p3 ...) converted to the document's profile, color-mix(in srgb|oklab|oklch, ...) evaluated as CSS Color 5 defines it. Other spaces are approximated with a note; unreadable calls become a mid grey with a note. Bounded length, nesting and count.
The settings folder comes from craft-settings' rules: FIGCRAFT_CONFIG_DIR,
a `portable` file next to the executable (config/ beside it), then the
platform folder every earlier version used. The Windows portable zip ships
the marker, and a portable folder without preferences starts with a copy
of the platform folder's.
Direct3D 12 compiles with FXC and no device compiles wgpu's indirect-call
validation shaders, the two causes of "Parent device is lost" at start.
When the graphics still fail before the first frame, the app starts again
with the next of a fixed list of attempts (Windows: Vulkan, OpenGL; Linux
and FreeBSD: OpenGL; then lower requirements on the power-saving GPU), and
the last failure's message names what was tried.
Session::execute_as records the agent's presence: its name, the file, and the innermost layers its last edit changed or the selection it set, for 8 seconds after its last command. The app shows it as an avatar in the people row and an outline with a name tag on the canvas, in its own colour. Display only: no undo step, never saved, never synced to a live session.
While the interaction editor has an Open overlay action with Manual position open, the overlay frame shows dimmed and outlined where it opens, from the top-left of the layer that opens it. Dragging it sets the action's offset through proto.action.set in one gesture: the X/Y fields follow live and the drag is one undo step.
* M9: one name for comments and live sessions, shown in the Join dialog, kept in the browser, renamed live (#1380)
* M9: a reconnecting session's reset is its own helper (#1380)
* M9: a per-address budget for server admin requests, and join codes found by hash (#1075)
* M9: the server tests share one snapshot and address helper (#1075)
These scripts write no spaces between words, so a paragraph was one word
that only broke where it overflowed, mid-word (พัฒนาซอ|ฟต์แวร์).
breaks::word_breaks finds the word starts inside each run of them with
ICU4X's line segmenter (icu_segmenter 2.3, matching the icu_* crates in
the lock), and break_lines may break there when the next glyph starts a
new cluster. Where a run meets other text the UAX #14 subset decides as
before; a word wider than its box keeps #1400's emergency break.
Desktop uses the segmenter's dictionaries; the browser uses its LSTM
models (about 0.39 MB of wasm instead of 1.86 MB, which the 24 MiB web
gate can't take). ICU4X breaks between stray marks are filtered through
safe_emergency_break, so junk input never splits a cluster.

* M4: a letter and its combining marks shape with one font (#1478)

Every message (the first and each reply) gets `mentions`: {name, known,
you} for each @mention, by the rule the thread view highlights with
(figcraft_doc::mentions, now shared with mention_ranges). Names resolve
against the file's people and you; unknown names are kept with
known: false; a@b.com mentions nobody.
A mask group's pixmaps cover only where its mask or content can paint within the view, rounded out to whole pixels, drawing the same pixels (a 40x40 mask on a 3000x2000 view: 96 MB -> 61.5 kB). Isolated layers share a 2 GiB per-thread budget; a layer past it is left out with a warning.
* M2: components can't contain their own instances (#1084)
Edits that would make a component hold an instance of itself, directly, through other components or through another variant of its set, are refused with the loop named. Files holding such a loop open with one instance per loop detached and a note; a rebuild never expands an instance inside a copy of itself, so a loop merged in a live session stops growing.
* M2: a variant may hold a sibling variant's instance; only true loops are refused (#1084)
Each variant counts as its own component: refusals and open-time repairs apply only to a component leading back to itself through instances (an instance-swap value included), so files with nested sibling variants open unchanged. sync_instance_depth is split into match_layers and copy_layers.
With map: true, edit.duplicate also returns map: each original layer's id, descendants included (nested frames, groups, instances and their sublayers), paired with its copy's id, so a batch can edit inside a copy through a step reference instead of inspecting it. Without map the result is unchanged.
The batches a session keeps for apps that reconnect were bounded only by count on a desktop host
and a private figcraft-server (`max_log_bytes` defaulted to usize::MAX). It now defaults to
64 MiB, and figcraft-server takes it from a new `max_log_mb` setting (default 64; open to the
public, also at most a quarter of `max_file_mb` as before). An app behind the trimmed log catches
up with a snapshot, as it already did past the count limits. The protocol is unchanged.
Nine 8 MiB renames with default limits: all 75.5 MB kept before, 58.7 MB after.
Fixes#1069
Tools that act on a document, and the control methods engine.execute,
document.inspect, node.get and ui.render, take an optional `document`
(an open file's id from doc.list / document.inspect, or its path). The
call acts on that file and the tab in front stays in front, so an
attached agent keeps editing its own file when the user switches tabs.
Every replica placed a created, moved or reordered layer by counting each sibling that sorts
before it, so a batch of many layers under one parent took quadratic time, on the server's
single hub thread too. `Replica::slot` now binary-searches the `(key, id)` order on each side of
the layer's old place (a position change has already given it its new key). The order is
unchanged, ties and fractional positions included.
20,000 creations and 10,000 moves under two parents: 20.05 s before, 0.33 s after (debug build).
Fixes#1065
Every command an MCP client runs acts as the client's name from initialize (clientInfo.title, else .name) with ' (agent)' after it, or 'AI agent' without one, carried to the app as engine.execute {agent}. Its messages, reactions and read state are its own, and its messages are marked (agent: true in the file and comment.list, an Agent label in the thread). The user's name and comments made in the app are unchanged; in live sessions the name and marker travel with the thread.
The server's fixes for a refused batch walked every deleted layer's whole subtree again and
compared each document-level fix with all the earlier ones, so a batch deleting a deep chain took
quadratic time on the hub thread. Each subtree walk now stops at a layer already restored, and
document-level fixes are looked up and sent once per target. The fixes are unchanged.
A refused batch deleting a 20,000-deep chain plus 40,000 comment puts: 27.2 s before, 0.14 s after
(debug build).
Fixes#1063
* M8: large images on the canvas draw from a smaller copy (#1483)
An image shown smaller than its pixels draws on the canvas from a copy scaled down to 4096 or 8192 px on its longer side, cached beside the image in the same budget. Two 16000 x 10000 images (640 MB each) evicted each other on every frame that drew both; as copies they take 80 MB together zoomed out. Moving one over the other: about 2.1 s a frame before, 11 ms at fit and 15 ms at 30% after. Exports, thumbnails and views at 100% and closer draw from the image itself. Tests in large_image_tests; timings in large_image_bench_tests (ignored).
* M8: drop the ignored large-image benchmark; its numbers are in the PR (#1483)
The header check from #1491 moves to figcraft_format::jpeg so the format crate and the renderer share it, and decode_thumbnail now refuses a progressive JPEG that samples a component more finely than its first (zune-jpeg 0.5.15 asserts on it; in the browser a panic aborts the page). A crafted file's thumbnail on the home screen and in recent files shows no picture instead of crashing. Regression test through decode_thumbnail and archive_preview.
Style links that name a library style by its asset key and version resolve to the file's copy of the style, as variable links already did. The linked text style beats the copies of its values below the row that links it; rows above that one still win. Override rows that restate a nested level (overrideLevel) apply at that level instead of in wire order.
