Subject: [PATCH 1/5] fix(doc): stop frame_relative on a looping parent chain

A restored dev snapshot can replace an ancestor with a historical
descendant while the root keeps that ancestor as its parent; frame_relative
walked the parent chain without a guard and never returned. It now stops
after more hops than the document has nodes, as is_ancestor does.

Subject: [PATCH 2/5] M12: connectors attached to a side start 4 pt outside the
 border (#1916)

A connector end attached to a side was routed from the middle of that side, so the stroke's
centre line started on the border and half its width plus the round cap lay on the fill, and
several connectors leaving one side piled up into a knot sticking into the card. FigJam starts
the line a few pixels outside the border and connectors leaving one side run together along the
side's normal before they fan out (the issue's screenshots). `board_route::END_GAP` (4 pt): an end
attached to a side (`RouteEnd::Box`) starts that far outside it along the side's normal; an end
placed by hand on the object (`RouteEnd::On`) keeps its exact point; a free end is unchanged.
The pinned route coordinates in the engine, format and UI tests move with it; the overlay's
attach points stay on the border. Docs: the Connectors rows, status line and history of
boards-parity.md.

Subject: [PATCH 3/5] M12: a connector joined to a layer inside a moving
 section is no snap target; the docs say which connectors share a run (#1916)

Review: a section moving carries its stickies and their connectors, so those connectors and
their labels are no snap targets for the section either (an end counts as carried when its node
or any ancestor is moving). The parity rows, the END_GAP doc and the test's doc no longer say
connectors from one side run together: elbows share their first run along the normal, curves
leave tangent to it, straight ones fan out from the same point.

Subject: [PATCH 4/5] M9: one auto layout edit on each side of a branch is one
 conflict (#2026)

A padding changed on both sides of a branch gave a conflict for every size and place auto
layout worked out from it: the component's, each instance's and their hugging parents' width
and height, each instance's layout, and every child's position (10 in a file with one instance,
138 with 15). The merge was refused until each had a side, yet the merged file laid itself out
again from the padding whatever they got. A `layout` conflict also took all auto layout fields
together, so a gap changed only on the branch was lost when main won the padding.

`merge::plan` now leaves out properties both sides changed to values both files work out for
themselves (`Plan::derived`): a hugging auto layout frame's or a filling child's size, text
sizing to its characters, an auto layout child's place (when both sides turn and scale it the
same way), and a value a layer in an instance has as its main's layer has it. Merging keeps the
file merged into's own value and normalising lays it out from the merged inputs.

`layout` and `childLayout` merge field by field: a field changed on one side (or the same way on
both) merges, and each field changed both ways is a conflict of its own (`Key::Field`,
`<id>/layout.padding`), written whole from the merged fields and each picked side's value. The
review shows it as "auto layout padding" with both sides' values ("8, 8, 8, 8").

Tests: `branch_tests::one_conflicting_auto_layout_edit_is_one_conflict` (the issue's file: one
conflict, either side laid out as if set directly), `auto_layout_fields_changed_one_way_survive_a_conflict`
(merge and update from main), `sizes_auto_layout_works_out_never_conflict`; the merge fuzz test
leaves worked-out values out of what each side must show. Docs: collaboration-parity.md, mcp.md,
ROADMAP.md.

 **Stage: alpha** · next: beta, ~26 points and ~162–292 h away (one Opus 5.5 agent; ~33–67 h wall-clock with 5 agents)
 
-> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-11-02 · **Change:** minor (glass bends towards its core, and rounded rectangles work it out in closed form; glass's light is a line on its bevel and splay turns the bend towards the centre; glass bends with a thick-lens profile and splits its colours over 8 steps; glass effects take variables and keep their frost within 0–100; web host bridge: `?host=parent` or `data-host="page"` hands a page the app's files, documented in the hosting guide; a connector end moved with Cmd/Ctrl held goes on any part of an object, and stays there as the object moves or resizes; a tap on a plugin panel's button keeps what was typed in its fields; a Dash cap setting (none, round or square) on Dash and Custom strokes, drawn on both ends of every dash; library analytics list how many layers and files use each style and variable; the Controller menu names each button as PlayStation and Switch controllers do; widgets draw lines and SVG pictures (plugin API 6); a connector end dropped along a side of a shape attaches to that side (#1708); regression tests pin a rounded shape's one-sided stroke and SVG ids and font families without XML-forbidden characters (#1351, #1124); a damaged image is refused with a reason instead of showing as an empty box (#1474); an image copied in another app pastes again on the desktop, and in the browser for the first time (#492); SwiftUI and Compose code names a bound variable by its iOS or Android code syntax; the colour picker's Image tab shows a placeholder and Upload from computer, an asset preview, and a file dropped on it replaces the image, keeping the fill mode, crop and position (#1682); the Frame tool's Phone presets have the iPhone 17 family (#1691); Show in folder works in the Flatpak build and selects the file on Linux (#1701); a dashed line starts and ends with a half-length dash, on the canvas and in exports; the Pages, Layers and Assets search fields keep their text in the middle of the field (#1703); a board connector's path can be reshaped by dragging its path handles (#1710); boards have 16 more shapes (arrows, polygons, star, plus and flowchart symbols), in pickers that lay them out in a grid; library analytics count insertions and show insertions and detachments over the past 30 days, 90 days or year; a stroke's Custom style takes a dash pattern of any length as a comma-separated list (#1681); a control request can set its own timeout, up to 10 minutes (`timeoutMs`; `figcraft-cli mcp --attach PORT --timeout SECONDS`) (#1696); gap 6: a widget opens its plugin's panel (plugin API 5), whose callbacks redraw it; the keyboard's Menu key opens the context menu, as Shift+F10 does; an Open link action can open in place of the prototype, with "Open in new tab" off (gap 15); a collection of this file can be extended (Extend collection on its row, `variable.extendCollection`), its extension following its edits at once, and extended collections extend again in the file; the eyedropper with Cmd/Ctrl+Shift makes a colour style or variable of what it picks; a live session's welcome sends the document compressed to clients that read it, about seven times smaller (#1665); a control request that times out says truthfully whether it was dropped or is still running and will take effect, and only screenshots and input blame the window (#1673); a board keeps earlier votes' results, listed newest first in Results and deleted one at a time; the object a stamp will stick to is outlined while the stamp tool is over it or a stamp is dragged over it, and board objects take no drops (gap 24); a server can list the files shared from it now for everyone who reaches it, Home ▸ Online shows them and their links carry no secret (`team_files`, part of #742); team library analytics count detached instances per component and file (gap 10); skipping the Open link notice by command is saved with the preferences at once (gap 15); a selected connector's bar on a board sets its start and end points, solid or dashed, its weight and any colour (#1596); cells copied from a spreadsheet paste onto a board as a table; a long layer name stays on one line in the Export button and the Dev Mode header, ending with an ellipsis, and no longer covers the Design panel (#1650); with hundreds of layers selected, the Design panel and the selection overlays stop going over the whole selection on every frame, so dragging 648 layers averages about 1.1 ms of UI per frame (#1571); plugin panels show pictures: an `image` control, base64 within 256 KB and 4,096 px a side, named by its label (gap 6); `.fig` connector labels without a saved snapshot are kept, centred on their line (gap 1); a drag moving many layers re-runs only what sits around them, not each layer's bindings, sizing, text and instance checks, on every move (#1571); damaged font tracking table offsets are checked instead of wrapping on 32-bit targets, and font indexing makes its existing offset bounds explicit (#1125); Bosnian (`bs`) draft catalog; text style dedupe is O(spans) via a last-two cache and fingerprint buckets (#1102); pasted layers whose image the clipboard lacks are named and show a placeholder that reads as missing (#1646); paint-style colours on layers pasted from another design app keep their style instead of turning black (#1638); progress docs cleaned of what merges left twice: rows merged into one, repeated status items removed, and `cargo xtask docs` (in `ci`) fails on a repeated table row or status item; a name typed for a variable or collection finds the one with that exact id before one named like it, and stored mode ids, font family variables and the panels' labels read exact ids (#1613); plugin widgets have hover styles: a layer's `hover` fill, stroke, opacity or text colour shows while the pointer is over it (gap 6); `.fig` elbowed and curved connectors without a saved path are routed like board connectors instead of drawn straight (gap 1); every file a command reads whole by path is a regular file within a cap that fits it: documents 16 GiB, placed images 256 MiB, CLI scripts 1 GiB; `figcraft-cli connect publish` publishes a code repository's code connect mappings to a design file (gap 16); while a drag only moves a large selection, its outlines, box, slots, spacing and Design panel values are worked out once and shifted, not rebuilt on every move (#1571); Shift+Cmd/Ctrl+Enter on a selected board shape adds the next shape already joined to it, and goes on typing (#1597); an imported or pasted file finds an installed family under the other names its fonts give it, and with other case and spacing, instead of reporting it missing (#1292); a development example generates figcraft-cli's shell completions and man pages from its clap definitions (part of #1396); `.fig` ZIP image reads share a total byte budget and count skipped images in the import warnings (#1076); German terminology corrections (M10): gradient stops, OpenType stylistic sets and the Home-screen preference; a component set's property rows fit the 240 px right panel: variant values wrap two to a line there and every + and − stays in view; the server key is checked by comparing SHA-256 hashes of the presented and the kept key, as the deployment guide says (#1130); opening a file contacts no team library server it names until you check it (#1097); a hostile server can no longer grow a client's memory with made-up people, and a session remembers a bounded number of deleted layer ids (#1121); `doc.list` gives AI agents and plugins the open files' names, not their paths (#1117); with a large selection, frames where nothing changed reuse the selection's outlines, box and slots and the Design panel's instance and position values instead of working them out again (#1571); team libraries and plugins larger than the 16 MiB download burst can be downloaded again, more slowly (#1089); a batch keeps one undo snapshot, not one per step (#1099); files nested 256 levels deep import on the browser's 1 MB stack (#1101); SVG and PDF exports count pattern sources and the renders they embed from the layer's depth, so one cap bounds a whole export (#1082); an explicit variables file path (`variable.import`, the `variables` of `file.open` and `file.import`) is refused past 256 MiB or when it isn't a regular file, as the sibling `variables.json` already was (part of #1114); joining and leaving a file nobody is editing reads and writes nothing on the server: it stays loaded a minute after everyone leaves (#1074); opening a `.figcraft` file unpacks at most 6 GiB in all (2 GiB in the browser), every area together (#1079); hovering the canvas hit-tests once per pointer move, not on every frame, and moving an auto layout frame no longer lays out its contents again on every move (#1571); `.fig` instance expansion no longer walks variable nodes for every instance or copies every outer override row into each nested instance (#1077); `comment.people` lists names that were only @mentioned, and `comment.next` and `comment.prompt` carry the mentions too (#1415); grid auto-placement looks for free cells a 64-bit word at a time and skips what blocks it, with the same placements (#1083); with the pen out, Enter or a double-click ends the path and edits the vector with the Move tool instead of drawing on (#1430); a recovery copy made while a version is previewed holds the file, not the version shown; a FigJam `.jam` file opens as a board (#1342); the Actions palette offers only commands that run from it, and no second row reading like a menu item: Place image opens the file dialog (#1574); share links can comment: a third access level beside edit and view, whose holder sees the file live and adds, replies to, reacts to and resolves comments but can't change the design; Preferences ▸ Scroll wheel zoom: a mouse wheel zooms the canvas about the pointer and Cmd/Ctrl+wheel scrolls (#1390); `comment.list {mentions}` lists only the threads that @mention a name (#1415); in the browser an internal error that stops the page keeps its unsaved files, which open again on reload (#1123); boolean operations refuse input past their caps, and a boolean group past them draws without its result (#1104); figcraft-cli parses its arguments with clap, following RFC-0012 (#1396); the selection and hover outlines of rounded rectangles and frames follow their corners (#1506); component properties keep the order they were made in when one is renamed, and Make slot asks for the slot's name first (#1536, #1537); the browser build publishes files to a server, so Share ▸ Online and Publish to server work there (#917); the browser build uses the fonts installed on the computer once asked, each read when text uses it (#1051); SVG import reads `color()` and `color-mix()` colours, with a note and a grey for those it can't (#1550); the portable Windows zip keeps its settings, recovery copies and plugins in `config\` beside the executable, starting with an installed copy's preferences; the window starts on other graphics when its first ones fail before the first frame: Direct3D 12 compiles with FXC and no device compiles wgpu's indirect-validation shaders, then Vulkan, OpenGL and lower requirements on the power-saving GPU (#965, #1438); Thai, Lao, Khmer and Burmese lines break between words (#1219); an AI agent attached over MCP shows where it works (#1416); a manual overlay's position can be dragged on the canvas (#405); one name for live sessions and comments: Preferences ▸ Your name, in the Join dialog too, kept in the browser, and a rename shows at once in the sessions you are in (#1380); requests that change a server's files have a budget per address, the server key's too, and join codes are found by their hash (#1075); the Join dialog shows a join from the click until its file is ready, with Cancel, and a failed join with Try again (#1381); SVG import draws each pattern tile once per scale, within the layer budget (#1080); Vietnamese letters typed with combining marks (decomposed) take one font that has every mark, instead of missing-glyph boxes beside the letter (#1478); comment.list reports each message's @mentions (#1415); mask groups draw only over the area they can paint, and nested isolated layers share one memory budget (#1061); components can't contain their own instances, directly or through other components; `edit.duplicate` returns an id map with `map: true` (#995); the batches kept for reconnecting apps are bounded in bytes by default, and `figcraft-server` takes `max_log_mb` (#1069); MCP and control calls name their document (#998); sibling placement in live sessions searches instead of counting (#1065); an AI agent attached over MCP comments under its own name, with an Agent label (#1414); the instance-swap menus have a search field (#1338); a refused batch's fixes take time linear in the batch (#1063); the connector tool shows the connector it will make while dragging, ends snapping to attach points (#1387); large images on the canvas draw from a smaller copy, so two 16k images no longer lag (#1483); a file's JPEG thumbnail can't crash the home screen (#1491's progressive JPEG check, now shared); `.fig` import: library text styles linked by asset key, and override rows restating a nested level (#1234); `.fig` import keeps the file's saved line breaks while the text and its box are unedited (#1236); Download a missing free font from the Missing fonts window (`font.download`, #754); the web build's wasm back under its 24 MiB gate (#1472); shadows of images with transparent pixels follow their alpha (#1289); Crop image: Object ▸ Crop image, the right-click menu and the image fill row enter crop mode (`image.crop`, #1464); offline Penpot 2.x import/export (#1143); optional batch continue-on-error with per-step outcomes (#1386); the Design panel's sections on one grid (#858); FigJam outer shape outlines and sticky body fallback beside author text (#1341, #1397); images placed at their own size, 2x screenshots in points (#1360); the toolbar on one 32 pt grid, without its Resources button (#1210); M4: zero-length round-capped dashes draw dots; dash expansion uses the existing safety budget; extracted from #1143; Arabic draft catalog; scaled instances keep their scale when their main is rebuilt (#922); .fig embedded images are copied once per blob, not once per hash (#1059); page ruler guides survive save and reopen (#1476); colour picker LCH and OKLCH models; non-ASCII layer names transliterate in code export (#1235); branches in live sessions and branch history entries, gap 17; plugin widgets take text input and a property menu (plugin API 4); boards: templates and tables; boards: a shared timer and voting sessions; boards: the dot grid, connector ends dragged to re-attach, curved connectors; Installed weights of an embedded font family (#1246); `.sketch` import, best effort (Sketch 48 and newer); CJK line breaking: JIS X 4051's line-start and line-end sets completed with the halfwidth small kana, the halfwidth and spacing (semi-)voiced sound marks, the iteration marks 〱–〵 and the halfwidth parentheses, with behaviour cases for each; Adobe Fonts found on macOS (#298); egui 0.37 hidden-capture deadline contract; Dev Mode measurements kept on the canvas and a read-only layers panel; boards: a board area row and progress entry; community fixes in #507, #510, #529 and #530: auto-save, a text box by dragging, batch step references, removing someone from a live session, Russian and Turkish catalogs reviewed, Czech and Indonesian drafts, the Japanese draft completed, zoom previews, the web clipboard, Alt-drag snapping and Cmd+D repeat, recovery copies, crash and rollback fixes, colour emoji, `.fig` import fixes;

 | Date | Change | Summary |
 |---|---|---|
+| 2026-11-06 | patch | M9, #2026: a branch merge counts one conflict per auto layout field changed both ways, not one for every size and place auto layout works out from it; values an instance takes from its main no longer conflict, and auto layout settings changed one way survive a conflict on another field. Tests: `branch_tests::one_conflicting_auto_layout_edit_is_one_conflict`, `branch_tests::auto_layout_fields_changed_one_way_survive_a_conflict`, `branch_tests::sizes_auto_layout_works_out_never_conflict`. Numbers unchanged |
 | 2026-11-02 | patch | M8, #1885: a glass whose shape is too big to keep whole at the zoom (past `MAX_SHAPE_PX` with its core's margin) bends along its edge normals instead of working out a core, so its fields never cover more pixels than a kept shape's, and the core's feature transform holds 16 bytes a pixel. The edge normals are box-blurred twice again and the bend directions once, as documented. Test: `glass::tests::a_shape_too_big_to_keep_bends_along_its_normals`. Numbers unchanged |
 | 2026-11-02 | minor | M3, #1885: glass bends the backdrop towards its core, the shape shrunk by `depth` and the bevel, as the reference tool's: round a sharp corner the bend turns smoothly instead of meeting along the diagonal, and a part thinner than twice that (a capsule, a letter's stroke) bends across itself towards its own middle (pixels about as deep as any within 2 px). Rectangles, frames, components, instances and sections whose corners aren't smoothed work their glass out in closed form, with nothing to rasterise, transform or keep: a zoom frame draws in 40 ms instead of 54 and a resize frame in 46 instead of 67 (`glass_render_timings`, release, 2×). Other shapes keep their fields, with the bend directions for the last two depths asked for beside them, so dragging the Depth slider works out only those again. Tests: `glass::tests::a_sharp_corner_bends_round_towards_the_core`, `glass::tests::a_thin_part_bends_across_itself`, `glass::tests::neighbouring_strokes_bend_towards_their_own_middles`, `glass::tests::a_rounded_rectangle_in_closed_form_matches_its_distance_transform`, `glass_cut_tests::what_the_shape_depends_on_works_it_out_again_and_nothing_else_does`. Numbers unchanged |
 | 2026-11-02 | minor | M3, #1885: glass's light is a line on its 1-unit bevel added to the backdrop, as the reference tool's: fully where the edge faces the light, none below 0.35 of facing it and 0.6 as much on the opposite side, with a faint gradient across the curve, 5% darker facing the light and lighter opposite (it was a glow mixed towards white, as deep as `splay` made it). `splay` turns the bend from along the edge's normal towards the way away from the layer's centre, as the reference tool's does, and no longer widens the light: files with a splay above 0 look different. The direction to the centre is worked out in the shape's own frame, so cut renders match. Tests: `glass::tests::the_light_lies_on_the_bevel_and_the_gradient_across_the_curve`, `backdrop_tests::splay_turns_the_bend_towards_the_centre`, `glass_cut_tests::the_light_is_a_line_on_the_bevel`.

+| 2026-11-06 | patch | M9, #2026: one conflicting auto layout edit added a conflict for every size and place it moved (a padding changed on both sides of a file with one instance gave 10, with 15 instances 138), and a `layout` conflict took all auto layout fields together, so a gap changed only on the branch was lost if main won the padding. `merge::plan` now leaves out values both sides work out for themselves: a hugging frame's or a filling child's size, text sizing to its characters, an auto layout child's place (when both sides turn it the same way) and a value a layer in an instance takes from its main; merging keeps the file merged into's own value and normalising lays it out from the merged inputs. `layout` and `childLayout` merge field by field: a field changed on one side merges, each field changed both ways is its own conflict (`<id>/layout.padding`, shown as auto layout padding with both sides' values). Tests: `branch_tests::one_conflicting_auto_layout_edit_is_one_conflict`, `branch_tests::auto_layout_fields_changed_one_way_survive_a_conflict`, `branch_tests::sizes_auto_layout_works_out_never_conflict`; the merge fuzz test leaves worked-out values out of what each side must show |
 | 2026-10-31 | patch | M9, #1665: the document in a live session's welcome goes compressed (deflate) to clients whose hello announces `packed`, about seven times smaller on the wire (a synthetic file of 4,040 layers: 397 KB to 53 KB); older clients keep getting it uncompressed, and the client reads a packed document only up to the size an uncompressed welcome could have had. |
 | 2026-10-30 | minor | M9, part of #742: a team list on `figcraft-server`. With `team_files = "edit"` (or `comment`, `view`) everyone who reaches the server sees the files shared from it now (a link of theirs has a join code: Share ▸ Start sharing) and joins them by a team list link, `figcraft://join?server=…&file=…&team=1`, which carries no secret: the server hands out the file's team link while it stays shared (`ResolveTeam`, answered like a join code), and Stop sharing revokes it with the others, disconnecting whoever joined with it. Turning the list off or changing its access refuses the old team links at once. `collab.files {refresh}` asks the server in Preferences for its list (`Admin::Team`; not the public server FigCraft ships with), and Home ▸ Online shows it below your own files: a row joins its file, its menu copies the link for the app or, with the server's `web_url`, for the browser build (`<web_url>#join=…`). A browser build served beside its server names it with `<meta name="figcraft-server">`, the page's default for sharing, codes and the team list. No accounts: the list is for a server only your team reaches. Tests: `team_tests` (the server and apps over loopback), `code_tests` (links and the browser's driver), `online_tests` (the Online section), `query_tests` (the page's server). Percentages and hours unchanged |
 | 2026-10-30 | minor | M9, #1130: `figcraft-server` compares the SHA-256 digests of the presented and the kept server key instead of the raw strings, as `docs/server.md` says; the key file, `figcraft-server key` and rotation are unchanged. Numbers unchanged. |

"Figma will try to determine which objects in a frame or component should be placed in an auto layout frame, then adds as many auto layout frames as needed to make the full design responsive ... while attempting to preserve the placement of your designs" (Toggle on auto layout in designs): `layout.suggest` splits a frame's layers into rows (Vertical) or else columns (Horizontal) by the gaps between their boxes, wraps each band of several layers in a new frame without fill or clipping that hugs it, and repeats inside it (16 levels, 1,000 layers per frame at most). The frame keeps its size; gap and padding come from the bands, so layers keep their boxes where the gaps are even and the bands start at the same offset; instances and layers inside them are refused; uneven gaps (smallest used), bands that start at different offsets across the flow (lined up at the smallest) and layers that overlap along both axes come back as `warnings`. `direction` sets the top level only; one undo step; `layout.add` is unchanged.

 | 2026-11-02 | patch | M2, #1824: fill container children share the free space by their content area: each one's own insets (padding and an included inside stroke, from the same `insets` the frame uses) come off the free space before the equal split and go back on its share, so a child with more padding or a thicker inside stroke takes a little more and the content areas match ("Figma distributes space amongst fill container children by the children's content area instead of by their size, matching the CSS border-box model", Use auto layout with CSS Flexbox in mind).

 | 2026-11-02 | patch | M2: a child of an auto layout frame resized to the full space available to it on an axis (the frame's size less its padding: across the flow for any child, along the flow for a lone child) becomes Fill container on that axis, whether by `transform.resize`, the W/H fields or a canvas handle ("Child objects of an auto layout frame will also be set to Fill container if they are manually resized to the full available space of the parent frame", Guide to auto layout). Any other size keeps the axis Fixed as before; beside siblings along the flow, in a hugging or wrapping frame, in a grid and for a layer that ignores the layout nothing changes.
