-## At a glance
-
-| Question | Answer |
-|---|---|
-| Where are we? | **M0 and M13 done; M1, M2, M5–M7, M9, M10, M14 in progress.** Sketch with solver and the full SKETCH create/modify set; extrude, revolve (two sides, symmetric, to object), fillet/chamfer (variable radius, chord length, a radius per edge, corner patches), holes, threads (cosmetic and modelled), patterns, mirror, shell (inside/outside/both), draft, loft, sweep, coil, split body and split face, delete face, construction planes, axes and points; persistent naming of faces and edges; parameters and configurations; components, joints, motion studies, exploded views; sheet metal and a plastic enclosure subset; STEP/IGES/3MF/STL/OBJ/DXF; FreeCAD/Rhino import; autosave and crash recovery; desktop and browser (wasm) app, CLI, MCP server. |
-| Features | Every registered command by area — [docs/features.md](docs/features.md) (`cargo xtask features`); registry breadth does not establish workflow or geometric depth |
-| Reference tests | [Current case count and results](docs/oracle.md): public cases in `tests/oracle/` with analytic or FreeCAD-computed expected values, checked by the reference-test job in [CI](.github/workflows/ci.yml). |
-| Tests | Solver, profiles, kernel booleans/blends/measures, expressions, timeline, persistent naming, file formats and migrations, assemblies, sheet metal, engine end-to-end, hostile-input fuzz over every command and headless UI scenarios. `cargo xtask ci` reports the current passing counts. |
-| Gates | `cargo xtask ci`: fmt, clippy -D warnings, tests, asset attribution, layering, wasm32 build — green |
-| Time to a useful alpha (M0–M6) | ≈ **82 agent hours** remain (sum of the M1–M6 estimates below) |
-
-Optional GPU viewport ambient occlusion is available in View settings and Graphics preferences,
-with persistent settings, Performance/Quality graphics presets (Quality combines AO, Fine tessellation and adaptive 2× supersampling; manual combinations show Custom), and the
-`view.ambient_occlusion` and `view.graphics_preset` commands. See [display settings](docs/ambient-occlusion.md).
-
-## Scope (owner decision, 2026-10-07)
-
-The issue batch adds preservation of blind pockets in through cuts, associative projected
-offsets and plastic face placements, XZ (+Y normal) with a v6 migration preserving older
-designs, interactive angle placement, file-picker sketch imports, Home/recent controls,
-toolbar overflow, and the remaining component-frame and assembly WIP work. The enclosure
-acceptance scenarios now include board resizes; STEP reopening is automated. See [WIP reconciliation](docs/wip-reconciliation.md).
-Face-based Extrude Join (including outward Press Pull) now defaults to the picked body,
-so edge-touching assembly neighbours stay separate regardless of body order (#226).
-
-In scope, in priority order:
-1. SOLID and SKETCH (now).
-2. Parameters / functional constraints (done: see `parameters.*`, `expr.evaluate`; unit-aware,
-   cycles reported with their path, rename follows references, deletes list their users):
-   user parameters with units and expressions (+-*/, ^,
-   parentheses, sin/cos/sqrt/min/max/floor/ceil/round, unit conversion), model parameters
-   d1, d2… for every dimension and feature input, references between parameters with a
-   dependency graph and cycle detection, re-evaluation on change, comments, favourites,
-   CSV/JSON import and export.
-3. Components and assemblies with joints (M9).
-4. SHEET METAL: flange, contour flange, bend, unfold/refold, flat pattern with DXF export, sheet
-   metal rules (thickness, K-factor, bend radius) (M10).
-5. A small PLASTIC subset for enclosures, after sheet metal: Boss, Rib, Web, Lip/Groove, Snap Fit.
-
-Deferred until further notice: MESH, FORM (T-splines), SURFACE beyond what solids need (scope proposed in #772), PCB / 3D
-PCB / Package, Render, Animation, Simulation, Manufacture/CAM, Drawings.

-| M1 | Sketch depth: command coverage implemented — projection/intersect/include as linked geometry (auto-project on faces, lost-reference warnings, break link), full SKETCH create/modify set (slots, polygons, tangent arcs/circles, ellipse, fit/control splines, conic, text, trim/extend/break, fillet/chamfer, offset, mirror, patterns, move/scale, blend curve, centerline), constraints incl. curvature and polygon with over-constraint refusal, Shift-picked line midpoints in Horizontal/Vertical using persisted points and ordinary constraints (#2087), driven/arc-length/linear-diameter dimensions, AutoConstrain, DXF/SVG insert, 3D sketch curves (Project To Surface, Intersection Curve, Isoparametric Curve, Spun Profile), exact free-form profiles (B-spline/NURBS edges, any spline degree, curves cut by crossings), sweeps and pipes along 3D sketch curves, canvases and decals, curvature combs. Exact free-form Extend and certified associative offsets now preserve geometry and IDs through edits, deletion and reopen. Occurrence-frame 3D wires now store explicit coordinate spaces and retain points and analytic fits through moves, refresh, undo and reopen. Constructive sketch solving (Owen 1991, Fudos & Hoffmann 1997) ahead of the numerical solver: points and rigid clusters are placed on the branch the sketch had, so dimension edits and drags keep their solution; edits that would turn a sketch over are refused; drags re-solve only the sketch per frame. Remaining workflow repairs: mixed offset junctions, legacy natural-spline seams, and damaged legacy wire links lacking frame provenance | in progress | 4 |
-| M2 | Robust modelling: coplanar booleans in the kernel, holes (placed on faces, at distances from reference edges, and on sketch points), threads (cosmetic, then modelled), patterns, mirror, shell, draft, split, construction geometry | in progress | 16 |

-| M3 | General fillets and chamfers (curved edges, chains, vertex blends); saddle rolling-ball surfaces now use continuous seam sections and arc-length fitting with shared contact boundaries and bounded accuracy checks; tiny rim edges remain selected instead of nearby wall seams when filleting (#2498) | in progress | 30 |
-| M4 | Files: STEP import (done — [docs/step-import.md](docs/step-import.md)), FreeCAD/Rhino solids through cadmpeg (done, desktop, browser and CLI), 3MF export and 3MF/STL import as mesh bodies (done), 3MF with B-rep face tags ([docs/formats/3mf-face-tags.md](docs/formats/3mf-face-tags.md), done), constant-section parametric mesh reconstruction, DXF sketches, OBJ import, PLY/XYZ point clouds as a modelling reference and PLY meshes (done — [docs/point-clouds.md](docs/point-clouds.md), #5151) | in progress | 6 |
-| M5 | Persistent naming of faces and edges (docs/book/src/dev/naming.md): faces named from their exact kernel-reported history (sketch curve sides, caps, revolve sections, primitive sides, blends, shell inner walls, pattern/mirror copies; split pieces told apart by the faces around them, lumps of a cut body named after their faces), edges by their faces; fillets/chamfers, sketches on faces, shell/draft/offset/replace faces, hole placements, joint origins and face appearances resolve by name first and warn when the entity split or vanished: done. sheet metal edges by base sketch line and flange side, shell inner faces, sweep and loft roles: done. kernel-reported face history: done (merged faces answer to every name; operations without history yet fall back to geometric names, flagged unverified; format 14 keeps older designs' geometric names). Left: history through sheet metal, plastic, surface and emboss features; FaceSource certificates through history | in progress | 20 |
-| M6 | UI depth: selection feedback and origin (done), timeline editing (done: hover and selection highlight modifier faces, including fillets and chamfers; edit feature, history marker drag, dependency-checked single and multi-item reorder, suppress, rename, delete with dependents, re-resolved references; redefining selections refreshes persistent edge/face references while retaining feature identity and dimension names; responsive feature history with width-driven icons/names/title, snapping width resize, bottom/left/browser-stack docking, shared-column collapse, rollback bar, multi-selection and persistent folders), right-docked dialogs (done), live previews for every feature dialog (done), keyboard-first commands with on-canvas value boxes and sketch inline dimensions (done), drag manipulators with automatic join/cut (done: extrude incl. two sides, fillet, shell, hole depth, move, pattern spacing, revolve rotator, extrude taper), dark theme (done), right-click menu with Repeat (done), measure tool (done), section analysis (done), selection filter (done), drag-solve of sketch points (done); appearance controls now preserve body/face/component targeting, named transparent looks, reuse/search and override removal; Browser Expand All / Collapse All (`browser.expand_all`, `browser.collapse_all`) on the design and component menus; preferences | in progress | 6 |
-| M7 | Thin extrude (walls along open or closed curves: centre, inside, outside or two sides; mitred corners, crossing walls joined; #721), sweep, loft (incl. to a point), rib and web (to next / depth), emboss (planar faces and exact radial emboss/deboss of bounded orthogonal profiles on complete exterior cylinders/sleeves), thread (cosmetic, and modelled M3–M20 outside and inside: the ISO profile screwed in as a faceted cut), coil (smooth B-spline helical walls), pipe, pattern on path, patterns of bodies and components, replace face (parallel), align, remove, feature copy/paste: done. Unique eligible cylindrical targets are inferred for new Emboss features. Left: general curved-face emboss and exact (unfaceted) modelled threads | in progress | 12 |
-| M8 | Surface workspace (#772). Done: Patch (sketch regions; edge loops filled G0, plus `crown`), Stitch, Thicken (planes and cylinders), Extend (straight edges of planar surfaces), Trim (by a plane, a face or sketch curves swept onto the surface, keeping a side or the picked regions; mutual trim of two surfaces, extended to meet and stitched, #767), Delete Face (healing), Boundary Fill, zebra/draft/curvature-map analysis, Surface Extrude/Revolve/Sweep/Loft from open and closed curves, Offset, Unstitch and Reverse Normal; the continuity-driven core (`kernel/src/bridge.rs`, G0–G3 Hermite rows) with **Blend** (`surface.blend`, #764: edge chains along one or several faces, closed rims paired seam to seam or from picked seams, a dialog), **Match** (`surface.match`), **Boundary** (`surface.boundary`, #763 — two sketch curves exact with G0–G3, three or four as the flat patch of their loop, and curve networks: Coons and Gordon surfaces through sketch, 3D-sketch or edge curves, a point for a three-sided side, G1/G2 against the faces along one direction's edges, joined into their body on request; G1/G2 on two sides that meet at a corner waits for the Gregory-type corner), **Fair** (`surface.fair`, CV fairing), **continuity analysis** (`inspect.continuity`, #770; a toolbar tool with edge markers and a legend, and curvature combs along face isocurves) and a multi-section **loft** with per-end continuity and crown, and guide rails on solid and surface lofts (one or two, scaling or stretching the sections between; #201). Also in the Class-A pass: G1…G4 blend curves in the sketch, chord and variable-radius fillets on curved edges (with honest refusals where the fit cannot hold), and a G2 corner patch where filleted edges meet (kernel; the command refuses until the patch's sections can be sewn to the blends' contacts). Left: bias/form-factor fillet sections (design recorded), a Gregory-type corner, surface Fillet between separate surface bodies (#769), Ruled (#762), Untrim (#761), curved-face Extend (#760), and every remaining #757–#772 item | deferred | — |
-| M9 | Components and assemblies: New Component / Create Components from Bodies, active component, per-component origin/bodies/sketches/timeline entries, occurrences with transforms, Copy/Paste vs Paste New, nested Browser tree with visibility and isolate; Ground, Move/Copy of occurrences, joints (rigid, revolute, slider, cylindrical, pin-slot, planar, ball) by joint origins with limits and Drive Joints, closed kinematic loops (four-bar, slider-crank: the loop's other joints follow the driven one on its branch, and driving stops where a loop can no longer close), cams (`joint.cam`: a revolute cam drives a slider or revolute follower along a closed sketch profile or the cam's edges, knife, roller or flat followers, worked out again when the profile changes; drives, studies, closed loops, contact sets), As-built Joint, Rigid Group, Contact Sets (driving and motion studies stop where bodies in a set would pass through each other), Motion Study (joint values keyed along a timeline, playback, export of occurrence positions as JSON/CSV), motion analysis (joint values and a point's path charted over a study as value, velocity and acceleration; the parts that collide along a study, with the steps where they do), Exploded views (automatic or by hand, shown without changing placements, and exported as an animation coming apart and back together); interference, per-component physical properties; STEP with assembly structure; URDF export for robot simulators (links with meshes, mass and inertia; joint chains whose values match Drive Joints; docs/urdf.md). Physical properties now measure material-aware component/occurrence placements, descendants and repeated instances, including pending moves and body reassignment offsets; contact geometry and automatic exploded centres respect those offsets. Groundwork done: component tree, occurrences with transforms (instances, Paste New), world placement, active component as authoring frame, ground, Capture/Revert Position, moving bodies and sketches. UI: ASSEMBLE panel dialogs for New Component, Joint (snaps on faces, edges, circles and vertices; animated motion preview; offsets, flip, limits), As-built Joint, Joint Origin, Rigid Group, Drive Joints (live slider), Motion Link, Cam and Interference (overlaps shown red); joints in the timeline and the Browser | in progress | 32 |
-| M10 | Sheet metal: flange (base, edge, contour), hem, unfold/refold, convert, flat pattern + DXF, rules: done. PLASTIC enclosure subset: Boss, Rib, Web, Lip/Groove, Snap Fit, Rest, Plastic Rules (library, edit, assign; rule draft and clearance as feature defaults): done, tested against hand-computed geometry. UI: SHEET METAL and PLASTIC tabs with dialogs (live preview, Edit Feature, pre-selection) for Flange, Hem, Unfold/Refold, Convert, Sheet Metal Rules, Create Flat Pattern (flat view with bend lines, bend table CSV/JSON and DXF export with exact circle/arc/line cutouts), Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Fold (bend along a sketch line); flanges meeting at a corner closed at any angle with the rule's gap; edge flanges with their own angle and height per edge in one feature; corner reliefs (notch, round, rectangular, tear) chosen by the rule; Convert to Sheet Metal from a solid or shelled body by its bend edges (flat faces, sharp bends) | in progress | 36 |
-| M11 | 2D drawings | deferred | — |
-| M12 | Release: cross-platform packages, verification and deliberate publication implemented; original current-UI demo refreshed. Trusted distribution signing and broader performance work remain | in progress | 16 |
-| M14 | Configurations: a table of rows (parameter expressions and feature suppressions per row) switched with config.activate (undoable, all or nothing), kept through parameter renames and feature deletes (config.configure, config.table, config.column/row/activate). Per-row body materials and appearances (library looks, custom colour/opacity and clearing overrides), undoable activation and save/reopen: done. Ordered typed configuration rules, atomic validation and structured rule editing: done. Component appearance and certified semantic face style columns, atomic preview/apply and independent-copy remapping: done. Exact constructed sketch-side and immutable imported-face lineage now preserve legacy names and reject retargeting. Left: ambiguous shifted/two-sided caps | in progress | 4 |
-| M13 | Never lose work: atomic saves (temporary file, flush, rename; a crash at any moment leaves the old file or the new one) with the replaced version kept as `<file>.bak`; autosave of unsaved changes to the recovery folder every 5 minutes (preference) and after big operations, only when something changed; "Recover unsaved design?" on the next launch (`doc.recovery_list`, `doc.recover`, `doc.recovery_discard`); a kill-mid-save test (process killed while saving a 0.5 MB design 25 times). File format: `"format": "solidcraft/12"`, older formats upgraded step by step (`doc::format`), newer ones refused with a message, out-of-range numbers and broken placements refused; a corpus of designs saved by M0, components-era, joints-era and current builds (apps/solidcraft-cli/tests/corpus) that must open and evaluate as saved; damaged and hostile variants (truncation, bit flips, hostile values, removed keys, repeated features, deep nesting) never panic | done | 6 |
-| M15 | Frames and weldments (#4003): structural members along 2D and 3D sketch lines, butt and mitre corners, trim to faces and bodies, end caps, gussets, cosmetic welds and a cut list. Done: the profile library (`frame.profile.list`, `frame.profile.properties`, `frame.profile.insert`): bar, round bar, rectangular and round tube, angle, channel and I-beam, each SolidCraft's own parametric definition with exact fillet arcs and exact section properties (area, centroid, second moments), tested against hand-computed values; members (`frame.member`): one body per straight line of a 2D or 3D frame sketch, following parameter edits, with a built-in profile (its dimensions parameter expressions) or a profile sketch (its drawn material by alternating nested loops), anchor, angle and mirror; each member's name kept with its line. Left: corners, trims, end caps, gussets, welds, cut list, FRAME tab and dialogs | in progress | 60 |
-
-M6 navigation preferences include **Touchpad**: Shift + pointer movement pans, Alt/Option +
-pointer movement orbits without a mouse button, and vertical scrolling zooms. Other presets
-retain their saved two-finger scroll preference; camera motion is available through
-`view.navigate` and modifier-aware `ui.move` automation.
-With the **Fusion** preset and two-finger pan enabled, two fingers pan and Shift + two fingers
-orbit freely, with pinch zoom and mouse bindings unchanged. The shared navigation handler
-applies the same gestures to model and Render views and blocks orbit on flat pages.
-
-UI redesign (#2016): the File/start view (#2027) uses shared light/dark navigation,
-action tiles, recent rows and sample cards, with recovery review and Save As/Export
-entry points. Document loading, sample caches and recovery safety retain their
-existing command paths.
-
-M11 precursor: File → Export Current View as DXF exports shown placed bodies and sketches from the current
-camera as a 2D millimetre drawing, with hidden edges omitted or dashed. Vector occlusion splits
-partly hidden edges and includes curved silhouettes. Repeated part meshes and triangle
-hierarchies are shared; bounded desktop preparation and occlusion use up to eight workers.
-Curves are approximated; drawing sheets,
-annotations and exact projected curves remain deferred. See [view DXF](docs/view-dxf.md).
-
-Drawing foundations: [RFC #860](https://github.com/tangency-labs/solidcraft/issues/860)
-and the [foundation ledger](docs/drawing-foundations.md) track the bounded implementation
-packages. The first geometry increment defines validated section records in a plane-local
-frame; the ledger separates that contract from section producers and the Drawing workspace.
-
-Desktop view DXF export runs in the file-operation worker with five-stage progress and
-cooperative cancellation. Curve tolerance (0.0001–1 mm, default 0.01 mm) is remembered alongside
-the hidden-edge setting. Cancelled exports preserve the model and the previous destination;
-completed drawings publish atomically. The browser still exports synchronously.
-
-## Interactive modelling
-
- Modelled threads preview their cut before OK using the background worker on desktop.
-  Browser users apply the cut with OK to avoid blocking on every edit.
-
- Thread resolves a suggested metric size when a cylindrical face is picked. Diameter and
-  pitch selectors expose the existing metric designation parameter; custom designations stay
-  editable, and Automatic size returns to the face's suggestion. Cosmetic/modelled and
-  full/partial-length options remain available. This does not add tolerance classes or
-  left-hand threads.
- New Body extrusion and face-offset previews show completed intermediate geometry while a
-  drag continues, then catch up to the exact final value. Changes to the selected geometry,
-  operation or feature still discard obsolete results. Distance arrows and their value boxes
-  follow the current frame's input.
- Large fine modelled threads use pitch-based helix resolution and tighter faceted
-  reconstruction fallbacks, preserving thin crests and closed shells on large shafts.
-
-## Physical material data
-
- Physical material card validation (#923/#922) provides typed SI mechanical and
-  thermal data, per-property sources/conditions and isotropic/orthotropic stability
-  checks through read-only `material.properties.validate`. It does not assign or
-  persist properties, provide a solver or enable rendering; see
-  [the contract and staged follow-ups](docs/physical-material-cards.md).
-
- Directional elasticity (#994) queries the validated card in material-local axes
-  through read-only `material.properties.directional`, with source/condition review.
-  It does not assign body frames, predict structural behavior or enable a solver.
-
-## Library foundations (#785, #786, #787)
-
- Local scalar libraries (#846) inspect/export bounded portable catalogs and copy exact
-  selected appearance/material revisions into existing design definitions in one undo step.
-  Appearance offers local loading/search/export; physical materials use existing commands.
-  This slice is independent of the render stack and does not change the document format.
-  See [the contract and limits](docs/book/src/dev/local-libraries.md).
-
- Proposed phases cover offline bundled/project/user packs, physical materials and
-  appearances, editable wood mapping, and parameterized component/assembly families.
-  Stable identity/revision, copied design definitions, provenance and resource limits
-  apply from the first implementation. Existing material, appearance and standard-part
-  commands remain the application paths. See [the proposal](docs/book/src/dev/libraries.md)
-  for source/license review and acceptance gates. This is planning only: pack loading,
-  texture rendering and expanded component families are not implemented by this entry.
-
-## Render foundation
-
- Original starter appearances (#1722): 34 opaque recipes through existing commands, with six explicitly unavailable glass recipes and preserved legacy looks; see [the contract](docs/render-starter-appearances.md).
-
- Bounded linear film accumulation (#1696) supplies caller-admitted mean/variance storage and complete-pass views; actual progressive consumers remain separate. See [the film contract](docs/render-film.md).
-
- Definition-local visual mapping (#1214) supplies a bounded numerical frame, physical repeat coordinates and a deterministic one-time grain-axis suggestion. It adds no saved record or texture consumer; see [the mapping contract](docs/render-visual-mapping.md).
-
- Explicit texture normalization (#1218) produces completed float RGBA with
-  role-aware linear color/data semantics, bounded matrix/TRC ICC conversion and
-  opt-in EXIF orientation. It retains high-precision raw samples and records lossy
-  gamut clipping only when explicitly requested. It is not a renderer/resource
-  consumer; see [the supported policy and limits](docs/render-texture-normalization.md).
-
- Opt-in opaque PBR (#1046) connects persisted surface parameters to the integrated
-  product viewport and CPU PNG, using a fixed direct-light studio. Geometry and mass
-  stay unchanged. HDRI, transmission and textures remain separate gates.
-  See [the consumer and limitations](docs/render-opaque-pbr.md).
-
- Combined integration is tracked in #842, with independent scalar libraries in
-  #863 and richer PBR/material-card transport in #1086. See [phase boundaries and validation gates](docs/render-integration.md).
-  Render/library consumers use the merged asynchronous picker (#1127). Material-card
-  UI (#1094), texture mapping and HDRI lighting remain explicit follow-ups.
-
- R4a adds bounded CPU product-image jobs, cancellation and atomic PNG export through
-  engine commands, the Render panel, CLI and persistent MCP. Immutable captures and
-  results stay outside persistence/undo; native workers and cooperative browser tasks
-  share the same work protocol. See [jobs, limits and export](docs/render-jobs.md).
-
- R3 adds an overlay-free product scene and the integrated Render workspace, with
-  runtime GPU host capabilities, per-document drafts and named camera/background
-  controls. Design keeps its camera and drawing policy. Raster transparency remains
-  approximate; PBR and environments are later slices. See
-  [workspace and scene contracts](docs/render-workspace.md).
-
- R2 adds bounded named render setups in document format 21 and the read/save
-  `render.settings.get/set` commands. Proven render-only changes preserve geometry
-  and prepared world data through undo/redo and checkpoint restore. This slice does
-  not add a Render workspace, PBR, environments or image jobs; see
-  [settings and refresh policy](docs/render-settings.md).
- Bounded PNG/JPEG texture admission (#900) validates in-memory sources and returns
-  completed RGBA8 pixels with explicit color/data roles. It is an input utility only:
-  ICC/16-bit normalization, local wood mapping, resource persistence and the renderer
-  consumer remain separate work. See [limits and licensed-file probes](docs/render-texture-input.md).
-
- The initial opaque surface numerical contract for #1004 provides bounded linear
-  color/metallic/roughness/IOR admission and an original tested direct-light BRDF.
-  The numerical module alone advertises no capabilities; the installed consumer above
-  provides rendering. See
-  [the model, evidence and remaining consumer gates](docs/render-surface.md).
-
- A bounded cooperative Radiance RGBE input utility is available in L1 render;
-  it does not yet enable HDRI/PBR rendering or a document import command. See
-  [the input contract](docs/render-hdr-input.md) and #813 for integration work.
- R1 adds renderer-independent backend/profile metadata, strict request resolution and
-  bounded image/scratch admission checks, exposed by the read-only `render.backends`
-  command. It describes the current CPU raster snapshot path without evaluating the model.
-  The legacy Design snapshot route remains unchanged. Later slices above provide the
-  workspace/jobs and opaque PBR; HDRI and optional engines remain future work. See [the contract](docs/render-backends.md)
-  and [the phased proposal (#620)](https://github.com/bherbruck/solidcraft/issues/620).
-
-## Dimensioning and error reporting
-
- Operation length fields share design-unit defaults and input evaluation, including secondary
-  distances, thin walls, blend controls, sheet/plastic rules, joints and motion keys. Canvas
-  handles and sketch previews use the same lengths as committed geometry. Existing stored
-  millimetre values retain their size when edited in a design using another unit (#3271).
-
- MCP `execute` accepts `verbose: false`, sharing the compact reply helper used by
-  `batch`: body changes and created sketch IDs stay, while repeated lists are omitted.
-  Both tools retain full replies by default.
-
- Sketch Create groups drawing variants under Line, Rectangle, Circle, Arc, Slot,
-  Polygon and Spline. Each open part remembers its last interactive choice per family
-  across sketch sessions and document-tab switches; closing the part resets these UI choices.
- Inscribed, circumscribed and edge polygon tools preview their actual outline before
-  placement, including orientation and the selected side count.
- Construction (X) preserves the active sketch drawing tool, picked anchors and inline
-  dimension values, so line type can change while a shape is in progress.
- Planar sketch construction previews and hover feedback keep the same dashed pattern as
-  committed geometry; centerlines retain their dash-dot pattern.
-
- Point has a default Sketch CREATE toolbar button alongside the existing drawing tools.
-  Saved custom layouts are preserved; Reset Toolbar restores the default Point button.
- Construction planes cannot take an origin-plane name (XY, XZ, YZ, Top, Front, Right). Plane
-  arguments reject such a name when an older design's construction plane already has it. Use
-  the other alias, the construction feature's numeric ID or an explicit plane; existing
-  stored references keep their saved meaning. Section Analysis uses the same check.
- Sketch text can be edited from a letter interior or outline's context menu or the Edit Text command.
-  Interior selection requires every profile boundary to belong to the same text source;
-  the editor highlights the whole source without replacing profile selections.
-  Content, baseline X/Y, height and rotation update the original text source in one undo step;
-  cancelling or rejecting an invalid value preserves the sketch. Position and height fields
-  use the document units captured when editing starts; generated outlines remain associated
-  with their text source, and untouched inputs preserve their saved internal values.
-  Dragging a text outline moves the entire source in one undo step; Escape restores the
-  gesture. Move/Copy on a selected text outline provides unit-aware X/Y distances and rotation
-  about its baseline; copies keep an independent editable text source.
- Repeating the initial point of a planar multi-point sketch drawing tool is neutral: the tool
-  waits for a distinct point without a degenerate-shape error or history entry. Typed input
-  and programmatic commands retain their validation.
- Circular-pattern and angled-plane axes reject explicitly supplied malformed or expression
-  origins instead of silently rotating about zero. Numeric origins remain in millimetres;
-  associative axis expressions and construction-axis references remain unsupported.
- Single-line and rectangle-side dimensioning supports selecting a line or its two endpoints.
-  Type a value and press Enter to commit one undo step; rejected values remain editable and
-  cancellation leaves the sketch unchanged. Fit keeps geometry clear of the Sketch Palette
-  and navigation controls, including enlarged displays and nested pending placements.
- Sketch Dimension takes a line and a circle or arc (#1803): it measures from the line to the
-  circle's edge (the gap, 0 when tangent, or how far the edge reaches past a line that cuts
-  it), drives it like any other dimension and keeps the circle on its side of the line.
- Sketch Dimension takes a point and a circle or arc, or two circles or arcs (#4064): it
-  measures to the circle's edge (from the point, or between the two edges: the gap, 0 when
-  they touch, how far they overlap, or the narrowest gap between nested circles).
- Sketch annotations, live drawing lengths and Measure use document units. Inches show
-  three decimals and retain a meaningful fourth digit. Bare length dimension entry captures
-  the current design unit; changing units leaves existing geometry and expressions intact.
-  Component/canvas distance controls, sketch cursor coordinates, flat-pattern dimensions
-  and pocket depths, interference volumes and parts-library lengths also use design units.
- Curvature and Polygon constraints accept complete preselected operands. Fix/Unfix
-  consumes complete point/curve selections consistently; mixed or ambiguous selections
-  retain the picking workflow. Rejected constraints preserve selection and undo history.
- Contextual error reporting: a **Create Issue** action beside feature errors opens a
-  reviewable GitHub issue draft with the error, operation settings, build diagnostics and
-  useful reproduction context. The draft is editable, with optional capture of the actual
-  viewport and copy/save controls. Opening GitHub does not submit the issue. Help also exposes
-  reporting for unexpected results that did not produce an error.
- The header exposes **Report a bug**, including an accessible compact control on
-  narrow windows. It opens the same editable report and screenshot review without
-  changing the active model or a pending dimension.
- Crash reports: every panic (in a command, in the kernel, anywhere else) and every unclean
-  exit (abort, stack overflow, kill: found at the next start through a locked per-run command
-  journal) leaves a local report with the backtrace, version and commit, the command and the
-  design that reproduce it (`solidcraft-cli crashes replay <id>`). Repeats are counted, not
-  rewritten; at most 20 reports, 50 MB and 90 days. The app shows them after a crash (Help >
-  Crash Reports…) with a reviewed issue draft; agents read them through
-  `diagnostics.crash_reports`, the MCP `crash_reports` tool or the CLI. Nothing is sent
-  anywhere. See [crash reports](docs/crash-reports.md).
- Agent chat (off by default, desktop): a side panel that drives a coding agent the user
-  already has (Claude Code through its ACP adapter, Codex, Gemini CLI, OpenCode, Grok Build, …) over the
-  Agent Client Protocol, under the user's own login; SolidCraft stores no keys. The agent works
-  through SolidCraft's MCP tools on a gated endpoint of its own: file actions wait for Allow or
-  Deny, crash reports are off limits, 24 changes per message, one undo step per message, and
-  the agent's whole process group ends with the panel or the app. Docks left or right,
-  minimises to a strip. Grok Build discovery includes `~/.grok/bin` and reuses the user's
-  Grok login. See [agent chat](docs/agent-chat.md).
- Command scripts from designs (#886): `timeline.export_script` (CLI `solidcraft-cli script`)
-  writes a design's history as a script that `eval` and `run` replay into the same design —
-  user parameters, units, sheet metal and plastic rules and materials as their own commands,
-  then each feature through `timeline.add` with its ids, names and dimension parameters kept,
-  so every feature kind replays exactly and a failing feature fails the same way. Trimming the
-  script after a step gives the design at that step. Appearances, folders, views and
-  configurations are listed as left out; components and joints are not supported yet.
-
-## 0.2.0 release batch
-
- Includes the new axis navigation, adaptive sketch drawing/picking, origin-corner repairs,
-  durable supported profile/face references, endpoint dimensioning and contextual reporting.
- Smooth ruled-wall display joins are hidden only within the supported geometric certificate;
-  authored splits and actual creases remain protected. Wireframe retains physical edges.
- Paste New uses a bounded current-geometry comparison for supported convex line/circle
-  prisms with separated circular holes; unsupported shapes retain the existing strict check.
- Common-bore Union retries check additional boundary curves before recutting the bore,
-  preventing the reproduced thin-web loss. Unknown additional trims refuse; inherited
-  common-cylinder trims retain their existing policy, so this is not a general Boolean proof.
- Exact full-path assembly joint editing remains separate work and is not part of this batch.
- Stable 0.2.0 is published: all release payload checksums, native cold reopening, deployed
-  web app and both Flatpak architectures were verified. The replacement README demo uses
-  the original electronics enclosure story and animated pointer in the actual English
-  0.2.0 UI, at 4× playback. Publication follows [the release workflow](docs/releasing.md).
-
-## 0.2.1 critical fixes
-
- Separated multi-profile Join/Cut extrusions into one solid target batch their tools using
-  conservative construction bounds, avoiding a Boolean rebuild for every profile. Live
-  extrusion previews build only their tools; confirmation validates the final Boolean.
- Coplanar selected body faces share one linked sketch and one extrusion. Automatic Join/Cut
-  keeps the evaluator's participant scope, including parts of an empty imported component. Desktop OK/Enter
-  computes on a scratch session in the background, with atomic acceptance and cancellation.
-  Planar section stitching projects lines/arcs analytically and removes duplicate endpoints.
- Imported rotated face groups can check all full start-face seams in one guarded
-  construction. Separated tools may batch a Join when each meets the same single body;
-  nearby uninvolved bodies retain the original contact decisions. Regression comparisons
-  cover all four extrusion operations.
- Inward multi-face cuts retain every eligible target and subtract separated tools together.
-  Safe interior classification handles roundoff at shared imported line/arc endpoints.
-  Straight extrusion feedback caches existing face/profile triangles and updates the display
-  directly, including a newly opened STEP's single identity component placement; other
-  extents, moved or repeated components and curved sketch profiles keep the Engine preview.
- The extrusion fixes retain tracked Boolean history and the current `solidcraft` packages.
-  Confirmation and tool previews use main's shared background calculation. Main's collapsed
-  blend-wall refusal and its tests are retained, including smaller valid radii and mirrored parts.
- Axis view and navigation controls stay anchored to the viewport when feature dialogs or
-  the command palette open, at normal and enlarged display scales. Fit still accounts for
-  dialog coverage; covered controls do not receive clicks through dialogs.
- Eligible planar faces survive fillet, chamfer and shell operations with exact source
-  certificates. Sketches placed directly on the enclosure wall and inner floor follow
-  width and wall changes, including after the USB cut and cold reopening.
- Remove artificial straight-wall and rounded-corner subdivisions left by shell and
-  extrusion cuts. Identical generated wall segments span adjacent slabs as one physical
-  face, with exact full-height supports and boundary stitching. Preserve authored face
-  splits and face appearances. Permanent regressions cover material, STEP, reopening and
-  unaffected bodies across the extrusion end plane.
- Feature dialogs use the available screen height for their fields, with OK and Cancel
-  outside the scrolling region, including enlarged display scales.
- Design format 13 records shell-face attachments. Older designs remain readable;
-  newly saved designs require 0.2.1 or later. Ambiguous or unsupported faces still refuse
-  attachment rather than guessing a plane.
- Saved projections from a removed strip retain their geometry and report the lost
-  reference. Explicitly reselect the wall to repair that projection.
-
-## Workspace layouts (#2029)
-
- General preferences save Floating or Compact using the universal UI containers.
-  Compact joins the workspace selector and ribbon, docks the content-hugging Browser
-  flush beneath them with a square join, and opens tool sheets below the compass.
-  Sheets remain draggable, rounding all corners away from their right dock; footer
-  backgrounds follow the same corners. A separate preference hides ribbon icon labels
-  for a shorter ribbon in either layout.
-  Assistant keeps the outermost edge and History keeps its chosen dock. Switching
-  retains the active tool, camera, selection and design; system windows and menus
-  keep their existing behavior.
-
-## View navigation
-
- Navigation has an opt-in Free orbit preference for mouse and 3D-mouse rotation through
-  both poles with roll. It defaults off, preserving existing preset snapping and pole limits.
-  The SolidWorks face menu offers Normal to Selection (`view.normal_to`), shared with Look At
-  and Ctrl+8, including repeat-to-flip, preserving scale and projection.
-
- Desktop Ctrl/Cmd +/- and 0 change or reset the saved UI scale. The scale slider keeps
-  its layout stable during a drag and applies the selected scale on release.
-
- OpenSCAD navigation preset: left drag orbits, right/middle drag pans, Shift+right/middle
-  drag zooms, and the wheel zooms. Available in the shared desktop/web Navigation preferences.
- Compact clickable signed X/Y/Z axis tips, smooth drag-to-orbit, and Shift-orbit snapping
-  to 26 standard and diagonal views. Pointer motion accumulates independently of a lightly
-  damped spring, with a boundary margin to prevent flicker. Z-up/Y-up and the nearest square
-  top/bottom heading are preserved. Diagonals include 45-degree edge and isometric corner views.
-
-## Known limitations
-
- Scheduled and manual CI scan locked dependency advisories, bans and sources with
-  cargo-deny. Vulnerabilities fail the scan; unmaintained crates warn. Local vendored
-  patches require separate upstream review because advisory databases cannot version-match
-  their path dependencies. Pull requests retain the existing licence checks.
-
- Associative shell-face sketches require a unique certified planar source. Nested shell
-  attachments and ambiguous coincident sources remain unsupported.
- G2 fillets: exact quintic blends of straight edges between planar faces, with one planar
-  end face at each end, including sloped ends (#2708). The UI and `solid.fillet` expose
-  `curvature` (alias `g2`); the size is an equivalent circular setback. Curved faces/edges,
-  multi-face ends and corner junctions remain unsupported.
- Fillets and chamfers: constant, variable-radius and chord-length fillets; a radius per edge,
-  rounds next to earlier rounds of another radius, and smooth corner patches where three rounds
-  meet (a sphere for equal radii); perpendicular corner fillets after a closed ring of earlier
-  rounds preserve the ring's radii and the enclosed planar face (#1557);
-  mitres between separate rounds of the same radius keep their endpoint tangent, so a later
-  fillet can select an upright and its adjoining bottom mitre as one chain (#2422);
-  straight edges (convex or concave) between planar faces with perpendicular
-  planar end faces (equal-distance chamfers also meet sloped planar end faces, including inner
-  basin rims within the rim width); convex fillets also meet sloped planar ends and reflex
-  corners around pocket rims, with unequal wall slopes and extensions confined to the face;
-  connected equal-distance chamfers also trim each other across unequal sloped rim walls;
-  curved chamfer chains with straight planar ends can terminate across two existing planar
-  bevel faces, splitting their shared seam; picks on the same tangent chain are applied once (#1303);
-  whole smooth loops of a planar face, picked whole or by one edge (tangent
-  chain), including circles and walls at any angle (boss bases and tops, bores, pocket floors,
-  plate outlines), loops with sharp corners between straight or mixed arc/line edges (straight
-  blends meet in mitres; perpendicular curved walls use offset intersections, with D-rim removal
-  checked within 0.1% of analytic offset slices), runs of
-  neighbouring edges along a planar face's loop (two top edges of a box: mitred, ending square;
-  with the edge between them too, the corner becomes a sphere octant),
-  rounded corners rounded again (sphere octants, tori at concave corners); every edge of a
-  convex planar body or of an extruded part; fillets inside patterns; closed chains of curved
-  edges between any two smooth sides (a branch pipe on a main pipe), by a rolling ball (the
-  blend a rational B-spline through exact arcs), closed or ending at planar faces square to the
-  edges, where straight or curved cap edges are trimmed to the contacts (the straight edge
-  between two overlapping extruded arcs); knife edges, where the two faces have opposite
-  normals (a wall that runs out tangent into a face: the ball that fits there); an edge that
-  runs out along an end face tangent to one side (the arc top edge of that wall), cut where the
-  blend meets it; rounds that end in an earlier round on curved faces, in any order (the rounds
-  of two edges at a vertex meet in a crease, as on a box), picked together or one after the
-  other, except a round after a round of the edge between the wall and a flat face that it
-  would run over; the three edges at a vertex of any smooth faces, of one radius, end in a
-  piece of sphere. A limiting blend that collapses a side wall into coincident boundary
-  curves is refused as too large rather than returning an unmeshable face (#1113).
- Booleans: prisms along one direction (plates with holes, slots, patterns of them, equal
-  sections stacked end to end) are combined exactly in 2D. Qualified axial cuts preserve
-  annular holes with overrun cutters, including inward Press Pull after a joined extrusion;
-  curved wall qualification rejects false transverse axes instead of filling holes.
-  Bodies touching along one whole face
-  (a part and its mirror image) are stitched; coincident planar faces are pushed apart when
-  their neighbours are planes or cylinders. Other coincident curved configurations can still
-  fail. Bounded containment classification preserves fully internal cavities and nested
-  material islands independently of shell order, with STEP round-trip and material-membership
-  regressions. Near-contact curved shells use the general boolean path rather than a
-  containment shortcut. Spheres are built from six pole-free patches.
- Mass properties come from fine tessellation (curved faces within ~1e-4 relative); triangles
-  that cut through curved faces (trimmed faces after booleans) are split onto the surface first.
- STEP import (our own reader, crates/kernel/src/step_in) reads solids (B-rep with analytic and B-spline geometry), units,
-  product names, colours and assemblies; analytic offsets on planes, cylinders, cones, spheres
-  and regular tori are read exactly (signed/nested distances, units and face sense). Freeform
-  offset surfaces and pcurve-only edges are not read yet,
-  and assembly components are flattened into bodies. Closed periodic faces (torus, B-spline
-  bands) are split in two for meshing; measure() uses a finer tolerance for small radii.
- Persistent naming follows the kernel's exact face history (docs/book/src/dev/naming.md):
-  references resolve by name first, follow splits and merges, and warn when the entity split,
-  merged or vanished, or was found by geometry only (operations that report no history yet).
-  New planar sketch attachments use exact box, extrusion cap/side and immutable imported-face
-  source certificates with checked target and author occurrence paths. A missing or changed
-  source fails explicitly; Redefine Sketch Plane previews reattachment or a fixed plane while
-  retaining current geometry and dimension identities. Unsupported modified faces need an
-  explicit fixed plane. Legacy attachments retain their original resolver behavior.
- Modelled threads are cut as a faceted body (curved faces within 1/200 of the pitch); Extrude
-  and Revolve To Object on a curved face cut the tool back to the target's surface.
- Explicit sketch breaks preserve exact ellipses, fit/control splines (including high degrees)
-  and conics; analytic trim/break also sees free-form cutters. Free-form curves cut at a tangent
-  touch (no clean crossing) enter that profile as polylines.
-  Sweeps along 3D sketch curves follow their polyline (smooth walls when the path is smooth).
-  A sweep with a twist, an end scale or a parallel or direction orientation (#771) follows its
-  path that way too, even along sketch lines and arcs: B-spline walls through stations, ruled
-  walls through denser stations where the path has corners or the profile has holes.
-  Guide rails (one or two, #771) do the same: each station meets every rail once, and the rail
-  turns the profile and scales it (or stretches it across to the rail) against the start; two
-  rails carry it between them. Rails along a path with sharp corners are refused for now.
- Extend intersects exact ellipses and rational/high-degree splines without moving the line or
-  circular support. Associative free-form offsets have a whole-span 0.002 mm normal-distance
-  certificate and refine within bounded node limits while retaining existing IDs.
-  At the node limit, geometric certificate subdivisions accommodate unequal spline parameter
-  speeds without changing stored nodes or relaxing the distance tolerance (#971).
-  Associated offset fit nodes stay hidden from display, picking and snapping; dragging the
-  editable source updates the derived boundary live. Break Association restores point editing.
-  Singular, self-intersecting and ambiguous curves refuse atomically; mixed junctions and nonsmooth
-  closed natural-spline seams remain limitations. New explicitly closed fit splines and closed
-  offset outputs use periodic C2 interpolation, supporting repeated certified offsets; older
-  natural splines are preserved. Clicking the starting fit point deliberately closes a new loop.
-  Newly captured adaptive profile references with complete source coverage retain their outer
-  and hole identities through span-count changes, including parameter edits after extrusion.
-  Partial, intersected or ambiguous boundaries do not qualify for these whole-source references.
-  Legacy curve-span multisets remain exact and unchanged; already-lost selections may need
-  reselection. Format 12 stores the new bounded whole-boundary references.
-  Projected analytic boundaries follow nested loop identities through resizing, including
-  stationary holes and rounded corners. Supported convex, tangent line-and-arc boundaries
-  can lose or regain corner arcs during an inset while preserving reserved curve identities
-  and linked profile selections. Format 12 saves those associations; compatible older closed
-  offsets upgrade structurally without changing their curve IDs. Breaking an association
-  freezes its current boundary and materializes downstream profile references. Child offsets
-  of a boundary with retired arcs still require breaking its association first; mixed or
-  nonconvex junctions and retained references to disappearing individual arcs remain limited.
- Extrude and Revolve editors retain original direction, extent expressions, explicit targets,
-  axes, From/To inputs and All-profile intent. No-op edits preserve downstream dimension names
-  and selected occurrence frames; cancel and successful edits preserve one-step undo history.
-  Placed feature edits preview through the edited timeline entry, and cylindrical Emboss guides
-  use the sketch's actual target, author or uniquely placed third-component frame.
-  Revolve rotators follow the actual signed axis and support symmetric and two-sided extents;
-  dragging a To Object extent converts its derived value to an explicit angle. Legacy reversed-axis
-  symmetric geometry is preserved through format 11's explicit legacy convention. New revolves
-  use the sketch-normal direction for each selected profile, including To Object and curved
-  target trimming, independently of the selected axis sign.
- Cylindrical emboss/deboss wraps bounded orthogonal line profiles, including holes, concave
-  outlines and nested islands, onto complete exterior cylinders or coaxial sleeves with exact
-  radial walls. New features infer a unique eligible cylinder when the face field is empty;
-  ambiguous targets require an explicit face. Saved target
-  and author occurrence paths retain the chosen placements; missing/split faces refuse rather
-  than retarget. General free-form profiles, seams, stepped cylinders and other curved surfaces
-  remain unsupported. STEP round-trip and independent radial/volume checks cover this subset.
- Shell and offset faces work on bodies of planes, cylinders, cones, spheres and tori (convex or not:
-  filleted boxes, bosses, domes, countersinks; corners where four or more planes meet, such as a
-  floor falling to a drain, as long as the corner's edges are all convex or all concave); draft on convex planar bodies and on walls (planes, cylinders → cones) between caps; lofts through three or more sections are smooth (B-spline sides through every section), two
-  sections ruled. Circular-meridian barrels retain curved inner walls through either axial
-  opening (#2421). Solid lofts preserve holes through sections with matching hole counts
-  (#2435), including inner walls and caps with openings; a hole cannot appear or disappear
-  between sections, and sections with holes cannot collapse to a point.
-
- Sketch corner tools: fillet and all three chamfer modes pick a connected corner even when
-  its endpoint overlaps the fixed origin or a loose point. Ordinary drawing still snaps to
-  the origin; clicked UI regressions verify geometry, closed profiles and undo.
- Sketch display: drawing, picking, highlighting, tool previews and profile shading share
-  adaptive projected curve boundaries. Fit, zoom, display scale and placed sketch frames
-  invalidate the display cache without changing CAD geometry or timeline history. Work
-  budgets and clipped paths prevent unbounded sampling or invented edges across the eye plane.
-  The Sketch Palette scrolls its options on short windows and enlarged displays while
-  keeping constraint status and Finish Sketch visible.
- Face projection: closed boundaries have a deterministic outer-first order. Refresh matches
-  existing geometry before assigning positions, retaining saved curve IDs and constraints
-  across enumeration changes and resize, including concentric circles. Ambiguous identities
-  retain the last geometry and report a lost reference; permutation matching is bounded.
- Project accepts complete supported preselection in one undo step. Visible external sketch
-  curves and points retain their source sketch identity; model geometry, axes and planes use
-  the existing linked projection commands. Rejection preserves the document and selection;
-  mixed selections retain ordinary tool-first picking.
- Inline sketch dimensions: Tab and Shift+Tab cycle within the active shape's value boxes,
-  selecting visited values for replacement. Expression completion retains forward-Tab
-  priority; real keyboard regressions cover rectangles, lines and single-value circles.
-  Typed lengths, radii, line angles, signed arc sweeps and slot lengths persist as constraints
-  and expressions through save/reopen. Shape creation and its dimensions form one undo step;
-  rejected values keep the editable field focused.
- Repeated components: Browser selection, visibility, properties, copy and Move/Copy use
-  checked occurrence paths. Active nested occurrences author planar sketches and solids in
-  their selected frame. Pending moves compose through parents; dialog cancellation restores
-  its selected move. Source materials and body/face appearances follow transformed instances.
-  Shared nested definitions remain shared. Deep Paste New copies reachable definition graphs,
-  independent feature/input histories, styles and internal motion records, with bounded geometry
-  checks and explicit external-link notices. Paste New selects the copy while preserving the active
-  authoring context. Imported periodic STEP seams survive placement and reexport with shared
-  topology and appearances intact. Recorded body transfers preserve historical Join/Cut membership,
-  material, placements and machining data through edits, copying, undo and reopen. New 3D wires
-  record their coordinate frame; legacy wires migrate from known provenance without changing
-  coordinates. Broken legacy links with missing provenance can require explicit refresh or relink.
-  See [occurrence workflows](docs/occurrence-workflows.md).
- Toolbar drops on panel labels, gaps and margins append commands with insertion feedback;
-  button drops keep insert-before ordering.
- Parameters and Configurations have distinct actions in the SOLID toolbar's CONFIGURE panel.
-  Parameters opens the user/model variable editor; Configurations opens the configuration table.
-  Configure remains available in the panel dropdown.
- Parameter creation supports Enter with validation and continued keyboard entry. Shared
-  expression autocomplete supports Up/Down selection, Enter/Tab acceptance and Escape dismissal;
-  accepting a suggestion does not submit a parameter or trigger viewport shortcuts.
- Movable window title bars follow the app's dark/light header palette. Radial right-click
-  menus are opt-in in Preferences > Navigation; ordinary context menus remain the default.
- Desktop distribution: running Windows windows and executable resources use the app icon;
-  packaging validates icon resources. Nix installs launchers, MIME data and generated icons,
-  with explicit launch apps and Vulkan-loader/driver discovery. Flatpak feed instructions
-  register the required runtime source; release checks exercise desktop modelling on X11/Wayland.
- OpenGL rendering clamps effective anti-aliasing to 1x across UI pipelines, textures and CAD
-  callbacks to prevent black frames. Other backends retain the requested sample count, and
-  stored preferences remain unchanged.
- Configuration rules: ordered typed conditions can drive parameters and suppressions or
-  restrict values. Preview explains effective values without modifying the document; applying
-  rules validates rows atomically. Length expressions retain their authoring units across
-  document-unit changes. The UI supports structured All/Any/Not conditions and rule ordering.
-  Component styles and certified semantic face styles are available; unsupported lineage refuses
-  atomically, and stale certified face paint cannot jump to another surface. See [configurations](docs/configurations.md).
- Sheet-metal material: inherited holes, crossing edge notches, overlapping cuts and retained
-  islands share the same boundaries in flat preview, DXF and unfolded solids. Detached material
-  pieces survive unfold/refold as one logical sheet group, including split flanged sheets.
-  Cut-outs made in the flat pattern cross bends at any angle or curved: their edges fold to
-  helices and curves on the bend, their walls square to the sheet. Free-form bases use bounded
-  sampling.
-  Parallel prismatic partial-depth cuts retain pocket side and depth through transfer and
-  unfold/refold, with separate pocket contours in preview and DXF. Planar Intersect preserves
-  exact holes and retained islands, including the union of multiple selected profiles, and
-  records complementary depth layers as pockets while retaining the stock gauge. Unsupported
-  tapered or bend-crossing machining refuses atomically instead of restoring material later.
-  Sketches attach to a sheet's flat faces (base and flanges, either side) by panel, in the
-  flat pattern's coordinates, and follow it through rebuilds and unfold/refold.
-  A flange on another flange's far edge (a return) follows that flange's closed end and keeps
-  clear of the flange beside it, and the returns of one feature are mitred toward each other
-  with the rule's gap where their flanges meet at a corner; returns of separate features, and
-  flanges on returns, are not closed toward each other.
- Rolling-ball fillet accuracy: independent offset-cylinder tee references check surface
-  distance, actual trimmed tessellation, supporting-cylinder contacts and tangency at two
-  scales. The measured trimmed-part error is below 0.0001 mm; this is an analytic geometry
-  check. Under-resolved fits return an error.
- Contact driving checks the trajectory between clear endpoints, including linked joints,
-  playback and sparse motion exports. Checks use bounded tessellation samples, not exact
-  continuous collision detection; local thin walls and small details remain limitations.
-  See [contact-set limits and recovery](docs/contact-sets.md).
-
-## Assembly dragging
-
-The design's first part is grounded when it is made, and a left-button drag repositions a free part (`occurrence.drag`: one undo step, exact occurrence paths including repeated jointed definitions, any floating-chain member carries the chain, grounded parts and joints hold where present, Escape cancels).
-
-## 3D sketch bridges
-
-3D sketch drawing snaps to points on other visible sketch planes without flattening them onto
-the active plane. Bridge endpoints capture their source positions; associative endpoint links,
-construction-plane selection of 3D wires and loft guide rails remain separate work.
-Feature dialog header chevrons collapse and restore the form without discarding selections
-or edited values, including the Appearance panel.
-## Construction on 3D paths
-
-Plane Along Path has a viewport path selector, fractional position, live preview and timeline
-editing. Construction planes and points resolve drawn 3D wires without applying their sketch
-plane a second time. Curved paths use sampled segments; multi-curve chains, absolute distance
-and reference-object placement remain separate work, as do loft rails and centerlines.
-
-## Design properties (#1015)
-
- Designs carry project, part number, revision, author, organization, description and licence
-  in an optional `metadata` object (File → Design Properties…, `document.metadata.*`,
-  `inspect_design`). STEP and IGES headers and 3MF model metadata take the fields their format
-  has a place for. Other tools keep their own data under a reverse-DNS key, kept as it is
-  through open, edit and save and never exported. See [design properties](docs/book/src/guide/files.md#design-properties).
-  Per-component properties (a part number per component) can follow with the same type.
-
-## Document-opening performance
-
- Desktop STEP import prepares consecutive independent solids in bounded batches with up
-  to eight workers, retaining serial traversal, result order and persistent source identities.
-  The web path remains serial. Original multi-solid fixtures show 64–81% lower complete
-  import times; single-solid assembly parts are not scheduled across nodes. See
-  [measurements and limits](docs/perf.md#parallel-step-body-preparation-2026-10-12).
- Design containers (#303, phase one) separate and deduplicate STEP, raw images and
-  lossless binary mesh arrays while keeping plain JSON as a supported Save As/export
-  format. Generated-mesh storage measurements reduce serialization and decoding work;
-  a seekable reader defers original blobs until after provisional display.
-  See [container format](docs/design-container.md) and [performance measurements](docs/perf.md).
- Warm saves with explicit `cache: true` can include a versioned native B-rep cache through SolidCraft-owned topology
-  and geometry records, with a separate truck adapter and bounded binary reader. Exact
-  face-source certificates and operation history survive codec round trips. A provisional
-  picture can be generated before original blobs are read; editing and measurement wait
-  for authoritative reconstruction. Cached metadata binds preview and reconstruction to
-  the same document despite concurrent file writes. Default saves omit this cache and never force cold
-  evaluation or meshing; explicit `preview: true` remains a separate warm-mesh option.
-  Keys, resource budgets and document/revision guards reject incompatible, hostile or
-  stale results. A second modelling kernel still requires its own tested adapter.
- Warm saves with explicit `cache: true` can also carry a bounded PNG thumbnail from already cached meshes.
-  Home reads it without rebuilding the design when its local picture is missing;
-  mismatched or malformed thumbnails fall back to normal generation. The image is
-  kernel-independent and saving never forces cold meshing to produce it.
-
- Cold rebuild profiling separates parsing, geometry, placement, display meshing and
-  thumbnails. Straight-line closest-point projection and exact curved-surface evaluation
-  reuse reduce repeated work without relaxing geometry checks. Three alternating optimized
-  benchmark runs reduce median rebuild time by 26% on the public sensor enclosure and 22%
-  on a local case assembly; shape measurements and topology match the original build.
-  See [performance measurements](docs/perf.md). Further cold Boolean and import costs remain.
- Prepared assembly geometry survives selection and view changes while real geometry and
-  placement changes invalidate it. A Pi assembly edge-selection probe drops from 9.24 s to
-  0.57 s; initial opening is unchanged. Actual Windows desktop profiling measures 15.87 s
-  median opening, with 82% spent rebuilding geometry; halving full opening remains open.
-
-## Kernel
-
- Successful Boolean retries report their strategy and numerical adjustments as
-  feature warnings and structured inspection data. Diagnostics survive cached
-  evaluation, undo/redo and cold reopening; the robustness runner counts retry
-  events by strategy and reports any bounded-log truncation. Existing geometry
-  acceptance checks remain in force.
-
- Cylinders of one radius whose axes cross (a second bore across a bore of the same size, a pipe
-  tee of equal pipes) touch at two points, where the mesh intersection cannot trace the curves
-  and a boolean cannot tell the four arms of the crossing apart. When the ordinary boolean fails
-  on such a pair, both faces are split along the line of their cylinder through the touching
-  points (the solids are unchanged), the boolean is taken of those, and its history is composed
-  back over the operands as given (#788). The result keeps the split lines as edges of the bore
-  walls. A crossing the ordinary route fails on and the split faces do not help (a radius of 17.5
-  in a 45 mm block with a tool of 80 mm) is still refused.
- Boolean intersection-curve construction refuses point-only, collapsed and non-finite
-  polylines without panicking. Direct constructor regressions retain valid open endpoints
-  and closed spherical intersections; the original interactive trigger remains unidentified.
- Shell of a stepped, joined planar body no longer creates horizontal subdivisions across
-  continuous walls. Fresh axis-aligned Cut walls are stitched using their exact construction
-  support and shared topology, preserving real steps and intentional boundaries. The local
-  reported case returns from 86 to 49 faces with unchanged material and bounds; regressions
-  cover stepped stock, STEP round trips and saved projections from removed pieces.

-//! Bringing the window forward when a close stops at "save changes?".
-//!
-//! A close from the taskbar or a window switcher reaches the window while another app has the
-//! focus. The prompt it opens is only seen once the window comes forward, so the window asks for
-//! the focus then. A window the user is already in is left alone.
-//!
-//! winit's Focus asks as an application, which a window manager with focus-stealing prevention
-//! (KWin's default) refuses for a window used before the switch away: it only marks the taskbar
-//! entry. On X11 the request is sent again with the source EWMH gives "direct user actions"
-//! (`_NET_ACTIVE_WINDOW`, source 2), which is what this is: the prompt is the rest of the user's
-//! close. Native Wayland has no way for a window to raise itself, so there the attention request
-//! (xdg-activation) lets the compositor raise it or mark its taskbar entry.
-//!
-//! When: not at once. KWin raises the window, then the taskbar's closing context menu hands the
-//! focus back to the app that had it, a few milliseconds later, and the window would flicker
-//! forward and back. So the window asks once the menu is gone, `FIRST_AFTER` the close. It asks
-//! again only if the focus is taken back right after it came (a slow menu) or never came; a later
-//! switch is the user's own, and the window stays where the user put it.

bherbruck	191e983423	Fix orbit about the picked point (regression in 0.16.0) (#2753 ) Orbiting about the point under the cursor (or the origin) turned the camera about its target and then panned to put the pivot back. The pan works at the target's depth with the parallel-view scale, so in a perspective view the pivot slid off its pixel and the model swung about the camera. The camera now turns rigidly about the pivot: Camera::orbit_about keeps the pivot's coordinates in the camera's frame and rebuilds the target from the new orientation, so the pivot stays exactly on its pixel in both projections. The Shift snap spring and view.navigate's pivot orbit use the same. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> (cherry picked from commit `e88779218`)	2026-10-19 00:38:52 +00:00

An old Intel Vulkan driver (igvk64.dll) crashed 0.10.1 at startup inside the driver. The app now probes D3D12, then Vulkan, then OpenGL, one backend at a time, and starts only the first with a hardware adapter (WARP when none has one). WGPU_BACKEND still wins; graphics.json's "backend" sets the order by hand; the software renderer (safe mode, the retry) uses D3D12 alone. A new Windows CI job starts the real app under several settings.

bherbruck	5ead82e627	Release 0.11.0: release branch follows main again after the 0.10.1 patch The tree is main at `cccbe125` exactly; `c29b0d2f` (0.10.1) is kept as a parent so release only moves forward.	2026-10-14 20:07:41 +00:00

bherbruck	480fd8d517	Fix the startup crash on D3D12 with FXC: CPU fallback for the tessellation pipeline, FXC-friendly shader (#1098 ) (#1099 ) * GPU tessellation: a pipeline the device cannot build falls back to CPU meshing instead of crashing (#1098) Build the tessellation compute pipeline inside error scopes; TessGpu::new returns an error, and the viewport logs it and meshes bodies on the CPU. A Windows CI job builds the pipeline with D3D12's FXC on the WARP adapter. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Tessellation shader: basis functions in one-dimensional local arrays, so D3D12's FXC compiles it (#1098) FXC has to unroll loops that write an array inside a struct (Basis.n0/n1) or a 2-D array (ndu) by a counter, and cannot with run-time trip counts (X3511). A2.2 basis functions in a local 1-D array returned whole; derivatives from the degree p-1 functions; the pole step offsets computed rather than indexed.

bherbruck	4c09fa5355	Hovered and selected faces light solidly again over GPU-drawn bodies (#1064 ) Since the model's mesh went back to the reference mesher (#940), the GPU viewport drew opaque bodies from their display plans while hover and selection lit faces with the reference mesh's triangles. Two triangulations of the same face at equal depth fought, so a hovered face shimmered in wedges instead of lighting whole. Faces lit over a body drawn from its plan now use the plan's own triangles (ModelBody::plan_mesh, evaluated once on the CPU), and the highlight pass gets a small depth bias toward the eye so f32 rounding between the GPU and CPU evaluations of the same triangles cannot speckle it either. Test: every face of a box with a pocket and a round boss, hovered and rendered offscreen through the viewport's real pipelines on the GPU path, lights the same pixels as on the CPU path (skipped without a GPU adapter).
