bherbruckandClaude Opus 5.5 d5b8aa0375 User scenarios in the real UI, headless: scenario::Harness draws the app frame by frame into an egui context and drives it with control-channel input (toolbar starts, clicks on world/sketch/origin-plane/axis points, keys, typing, drags) and checks the model; tests/scenarios/*.json: box with fillets, shell and hole; revolve on XZ; sketch on a face and cut; mirror; delete and undo. Control: ui.at, ui.dialogInput. Fixes found by them: a shape started on an existing point (the origin, a corner) is tied to it; the Dimension tool's value is edited in place with the value selected, so typing replaces it

bherbruckandClaude Opus 5.5 62dbf60eb2 Fix OK lost while a joint animates; Browser Joints folder inside the root component 
Clicking OK during the Joint dialog's motion animation was lost about half the time: the
preview's busy spinner came and went in the dialog footer between frames, shifting the
automatic ids of OK and Cancel, so a click pressed in one frame and released in the next landed
on two different ids. The spinner's place is now always taken. Reproduced through the control
channel (6 of 14 OK clicks at different animation phases lost before, 0 of 14 after) and
covered by a test that presses OK with the preview busy and releases it once idle.

The Joints folder is drawn by component_rows for the root, after its folders (as agreed with
solvecraft-shell).

bherbruckandClaude Opus 5.5 bdc15d2204 Start page and document tabs 
Start page (shown on launch without a file, and from the house button in the application bar):
New Design, Open, recent designs (kept in the preferences, newest first) and built-in samples,
each card with a picture rendered from the design in the background. Samples are scripts of
engine commands: the sample plate plus a sheet metal bracket, a hinge assembly with a revolute
joint, a plastic enclosure (lip, bosses, rest, snap fit), a bolted flange with a parametric
circular pattern and a vent plate with a parametric rectangular pattern (test: all build
without a failing feature).

Several open designs as tabs in the application bar: each keeps its own session (undo,
selection), camera and hidden/shown items; + and Ctrl+N open a new design, opening a file or a
sample uses a new tab unless the current design is blank, closing a tab with unsaved changes
asks Save / Don't Save / Cancel. Control channel: ui.documents and ui.home (docs/control-protocol.md).

bherbruckandClaude Opus 5.5 8ea38bc518 STEP export: undo face merging for a body when the merged faces do not read back cleanly 
With solvecraft-repo's curved-edge fillets (d72ec38), oracle 40's torus
groove comes out of truck in three pieces. Merging them made a band round the
torus whose single loop crosses itself, and the reader could not lay it out
("unsupported seam loop layout (2 runs)"). Each body's merged B-rep is now
read back. If that gives warnings and the unmerged pieces read cleanly, the
pieces are written instead.

bherbruckandClaude Opus 5.5 ae4570ed39 Colours in exports from materials and appearances; Appearance command 
- Bodies export (STEP, 3MF) in the colour they are shown in: an appearance,
  else the physical material's look, else the colour the body was imported
  with (Document::body_color / painted). Physical materials used to export
  no colour at all.
- AppearanceCommand (Modify): a colour per body ("#rrggbb" or [r, g, b];
  null follows the material again), kept in the design and across renames.
- Material looks move to solvecraft-doc (material_color); the viewport draws
  appearance, material or imported colour, as exported.
- Engine test: brass and red ABS bodies export, re-import with their RGB, and
  keep it through open and export again.

Dragging a curve of the sketch being edited now drags it (it used to start a box selection). Tests for per-entity fully-constrained feedback

bherbruckandClaude Opus 5.5 2db9e66048 STEP orientation check: judge only revolution faces, no drifting parameter hint 
Free-form strips (a curved-edge fillet's B-spline bands round a saddle) vary
their normal too much along the loop for the loop-direction test, and the
hinted nearest-parameter search drifted on them: false 'runs clockwise'
reports on faces that round-trip exactly. The check now covers cylinders,
cones, spheres and tori (closed surfaces, where a loop read the wrong way
silently gives the rest of the surface); volume checks cover the rest. It
still flags all 8 sphere corners of a fillet box with their sense flipped.

ASSEMBLE panel (SOLID, SHEET METAL, PLASTIC): New Component, Joint, As-built Joint, Joint Origin,
Rigid Group, Drive Joints, Motion Link, Interference. Joint origins are picked by hovering:
faces snap to their centre (round faces to the centre of the nearer end), edges to their middle
(round edges to their centre), vertices to themselves, shown as glyphs with their z axis. The
Joint dialog has the motion type, angle, offsets X/Y/Z, flip, per-value limits and Animate (the
preview plays the motion); joints and drives preview on the placed model (world states).
Drive Joints moves live with a slider. Interference lists the overlaps and shows them red.
Joints appear in the timeline and in a Browser Joints folder (edit, drive, suppress, delete).

SHEET METAL tab in Fusion's layout: Flange (base, edge or contour, from the picks; height arrow
on the canvas), Hem, Unfold, Refold, Convert to Sheet Metal, Sheet Metal Rules (rule manager),
Create Flat Pattern (flat view with up/down bend lines, bend table, DXF export).

PLASTIC tab with SETUP: Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Rib,
Web and the shared solid commands on the tab.

Every feature dialog has live preview, Edit Feature and pre-selection; icons drawn in code.
Toolbar layout per tab in workspace.rs; tests for the dialog to command mapping.

bherbruckandClaude Opus 5.5 7f9a8f2afd Two-entity constraints move only the second pick (tangent, parallel, perpendicular, equal, concentric, coincident, collinear, symmetric, midpoint): the constraint is applied with the first entity held (solve_holding), the second keeping its size where it can (lines turn and slide, circles translate), then resizing; if the second is fixed, projected or fully constrained the first moves instead, and if neither can the constraint is refused and nothing changes; later solves hold nothing. Context-menu constraints keep the selection order; a curve picked before a point puts the point on the curve

bherbruckandClaude Opus 5.5 7382ebd6e8 STEP export: Fusion round-trip fixes (sense, analytic surfaces, horn torus) 
- Surfaces of revolution follow ISO 10303-42 strictly in reader and writer: the
  normal is d/d(angle) x d/d(profile), the opposite of truck's revolution, as
  Fusion reads it (fixes Fusion inverting fillet sphere corners and the dimple).
  step_orientation_errors flags faces whose loop runs clockwise round their
  normal; engine, oracle and kernel round trips assert it.
- Revolved faces with analytic profiles are written as native PLANE,
  CYLINDRICAL/CONICAL/SPHERICAL/TOROIDAL surfaces, and the pieces truck splits
  a revolution into are merged back into one face per surface (with a seam
  edge for full turns), so face counts match other systems.
- A horn torus (tight sweep: tube touching its axis) is written as one rational
  B-spline face whose loop passes the pole twice, with truck's zero-length pole
  edges collapsed, instead of a degenerate surface of revolution; the reader
  starts such figure-eight loops off the pole (Fusion's own part 50 now imports
  with the right volume).

bherbruckandClaude Opus 5.5 df64a373b0 Sketch links: body-based references (edges, faces, silhouettes, sections, iso curves) are cached by model identity, so editing a sketch with projections no longer re-projects (30x faster per edit on a 20k-triangle model)
