+
+## 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.

Exact free-form Extend and certified associative offsets now preserve geometry and IDs through edits, deletion and reopen.

+| 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.
