Two behaviour changes that bring the command line in line with
established CAD workflow:
1. **Always-on keyboard capture.** The input was blurred whenever no
command was running, so typed letters went nowhere until the user
clicked into the field. Replace the blur with a re-focus on every
command lifecycle transition (cmd_result.rs) and on viewport / tab
/ ribbon clicks (update.rs), focus the input at startup, and add
a global key subscription that catches any unhandled character key
or backspace and routes it into the buffer via two new messages
(CommandAppendChar / CommandBackspace) — so the command line keeps
accumulating keystrokes even if focus parks somewhere not
focusable. Removes the unused blur_cmd_input helper.
2. **Space submits.** Typing a space at the end of the input now
submits the buffer the same way Enter does. Only exception: an
active command that's currently collecting free-form prose
(TEXT / MTEXT / DDEDIT body, ATTDEF prompt / default value,
INSERT attribute value, ATTEDIT cell). Those advertise the new
`CadCommand::wants_text_with_spaces()` flag so the Space character
reaches the buffer as a literal.

The same DXF/DWG bulge → (center, radius, sweep) formula was inlined
in six places (hatch outline, polyline tess + truck path, lwpolyline
×4, scene hatch fill, explode bulge_to_arc) — each with subtly
different sweep-direction handling for the bulge sign.
Add `entities::common::BulgeArc { center, radius, start_angle,
end_angle, sweep }` with one `from_bulge(p0, p1, bulge)` constructor
and a `sample(t)` helper. Callsites collapse to a few lines.
Net: -121 lines, one canonical sweep-direction convention shared by
all consumers.
array.rs (the path-along-curve f32 helper) keeps its inline math —
its sign convention is inverted relative to the others and changing
it without exercising the array-path command risks regressing the
output.

A pinned "Start" tab now lives at index 0. It cannot be closed, opens
on launch, and replaces the model-space viewport with a welcome page —
similar to Thunderbird's first-run screen.
- Boot opens with only the Start tab; Drawing1 is no longer auto-spawned.
- The Properties left panel becomes a Recent Documents rail on the
Start tab. Recents persist to disk
(%APPDATA%/H7CAD/recent.txt on Windows, $XDG_CONFIG_HOME/H7CAD/recent.txt
on Linux, ~/Library/Application Support/H7CAD/recent.txt on macOS), up
to 20 entries, saved on every open and rehydrated at boot.
Each row opens or removes the file in place.
- The Support ribbon group (Donate / Report / About / Changelog) is
retired; the same actions surface on the welcome page instead. The
Donate button is the primary call-to-action — solid #B03020 brand
fill with a soft brand-tinted ambient glow halo behind the action row
(Thunderbird-style coloured glow against the neutral page).
- Drawing-only overlays (mouse-area, viewcube, navbar, dynamic input,
selection markers) are suppressed on the Start tab so its clicks
don't trigger CAD commands. OpenFile's "current_is_empty" check
refuses to replace the Start tab, and TabClose ignores requests on
it.

Two precision problems were producing visibly wrong hatches on UTM-scale
(and similarly-offset) drawings even after world_offset was correct:
1. **Boundary tessellation** — `hatch_model_from_dxf`'s polyline-bulge
arc tessellation ran the whole arc-center computation in f32. With
vertices at WCS magnitude ~1e5 the f32 ULP is ~1 cm, which propagated
into the sampled arc points and showed up as visibly wavy / jagged
hatch boundaries on edges that crossed the long axis of the drawing.
Re-run the full bulge → arc math in f64; only cast at the to_xy
call that feeds the (also f64) boundary buffer.
2. **Pattern phase** — the per-fragment `perp / perp_step` modulo blew
precision when `xz` was at offset-rel WCS magnitude and perp_step
was sub-cm. Move the precision-critical bits out of f32 by keeping
each hatch's anchor in f64 on the model side: `HatchModel` now
carries a `world_origin: [f64; 2]` and the `boundary: [f32; 2]`
vertices are stored as small offsets from it. The GPU vertex shader
adds `origin` back inside the view_proj multiply for clip position
(sub-pixel-lossy at large hatches but invisible); the `xz` varying
that the fragment shader uses for in_polygon + pattern math stays
in hatch-local space at full f32 precision.
For pattern alignment across adjacent hatches with the same family,
the GPU pipeline snaps the anchor to the family's perp/along grid
in f64 before sending it down. Snap uses the same QCAD-PAT
convention (`fam.dy = perp_step`, `fam.dx = along_step`) the
shader's check_family uses — an earlier attempt used the world-frame
`(-dx*sin + dy*cos)` formula, which produced a meaningless grid and
no alignment.
Trade-off: pattern phase is "global modulo per-family-grid" rather
than tied to WCS (0,0). Same hatches still align with each other;
the absolute phase relative to the WCS origin may differ from the
pre-fix behaviour on small drawings.
Consumers that read `model.boundary` directly (hit_test, paper_canvas,
add_hatch round-trip) reconstruct WCS via `boundary[i] + world_origin`.
The hatch wgsl bind-group entry for binding 0 was bumped to
`VERTEX | FRAGMENT` because the vertex shader now reads `h.origin`.
The fragment-shader hatch LOD substitute + sub-pixel skip from e7675be
and the scissor plumbing from fbbac42 still work — those touched
different fields of the same struct.

* io/xref.rs — replaced the 7-line "BlockRecord::is_loaded turned out to
be unreliable" rationale with a one-liner. The reverted experiment
lives in git history (e88a946, 0996b75).
* refedit::RefEditSession.insert_handle — set at construction but never
read; the "kept for future REFCLOSE DISCARD" TODO can come back via
git history when that feature lands.
* scene::mod — dropped the placeholder MeshModel re-export; nothing
outside `mesh_model` consumes the bare name and MeshLodSet is the
pipeline-facing type now.

Wire pass already uses `WireModel.vp_scissor` to clip viewport-projected
geometry to its paper-space viewport rect; hatch / image / wipeout
passes drew across the whole canvas. When a future paper-space path
projects fills/images into a viewport, they would bleed past the
viewport frame.
Add `vp_scissor: Option<[f32; 4]>` to HatchModel and ImageModel
(mirroring WireModel), forward it through HatchGpu / ImageGpu, and add
per-pass `compute_*_scissors` / `set_scissor_rect` machinery. Factored
the wire-side scissor-projection math into a shared `project_scissor`
helper. Field defaults to None at every constructor site — no producer
sets it yet, so this is plumbing for the paper-viewport fill projection
that Phase 1.4 unblocks without changing current visual output.

Mirrored INSERTs reverse OCS handedness, but acadrust's explode used to
keep the original normal — making CCW-around-normal arcs and ellipses
sweep the wrong way. The fix lives in acadrust 7c711e9, which flips the
new normal when det < 0 and reprojects center/major_axis/angles into the
new OCS. H7CAD's fix_mirrored_arc workaround is no longer needed.
PolyfaceMesh and PolygonMesh were wireframe-only. They now render with
the same flat-color solid fill as Face3D entities.
- Add fill_tris: Vec<[f32;3]> to TruckEntity and WireModel
- PolyfaceMesh: fan-triangulate each face into fill_tris
- PolygonMesh: triangulate each grid quad into fill_tris
- tessellate.rs Lines branch: apply world_offset to fill_tris
- Face3DGpu::from_wires: collect fill_tris from all wires in addition
to Face3D key_vertices quads
- upload_face3d: pass all_wires so fill_tris are batched into one draw call
Viewport-projected wires now clip at pixel level to their viewport boundary.
- WireModel.vp_scissor: Option<[f32; 4]> — paper-space bbox set on projection
- WireGpu.vp_scissor carries it through to the draw loop
- Pipeline.compute_wire_scissors() converts paper→NDC→pixel each frame
- render() calls set_scissor_rect() per wire, reset after viewport group
- INTEGRATION_GAPS.md: Viewport ⚠️ → ✅, all 51 gaps resolved

LwPolyline PLINEGEN=0 (DXF default): emit SegmentedLines with NaN
separators between vertex-to-vertex segments; wire_gpu resets
arc-length to 0 after each NaN so linetype pattern restarts per vertex.
PLINEGEN=1: existing Contour path unchanged (continuous pattern).
WireModel gains plinegen field propagated through tessellate pipeline.
Solid3D/Region/Body: call SabReader::read() when parse_sat() returns
None due to binary SAB format (DWG files / newer AutoCAD exports).

Add `aabb: [f32; 4]` field to WireModel (world-space 2-D bounding box).
In tessellate_entity() set each wire's AABB from e.as_entity().bounding_box()
via new entity_aabb() helper; Insert sub-entities each get their own AABB.
Preview/interim wires and any entity returning a zero-extent default box get
UNBOUNDED_AABB so they are never pre-rejected.
Replace the chord-sphere heuristic in Snapper::wire_in_range() with a proper
AABB vs snap-circle overlap test. The new check is four scalar comparisons and
correctly handles closed curves (circles, arcs) which the chord-sphere approach
had to special-case.

- Arc rendering now respects the normal vector: when normal.z < 0 the
midpoint is placed on the clockwise side so the curve sweeps the right way
- Removed spurious .to_radians() / .to_degrees() round-trips in arc.rs
(angles are already stored in the unit the trig functions expect)
- apply_grip and apply_transform use consistent angle units
- normalize_insert_entity no longer converts arc angles; the old conversion
was only needed by the now-removed .to_radians() call in to_truck
- Added fix_mirrored_arc: swaps arc start/end angles when the INSERT has a
mirrored scale (x_scale * y_scale < 0) so exploded arcs curve correctly

REFEDIT picks an INSERT, extracts the block entities into model space
with the INSERT transform applied (translate + rotate + uniform scale),
and enters an editing session. Any normal modify command works on the
temporary entities.
REFCLOSE SAVE applies the inverse transform, replaces the block
definition, and rebuilds all derived caches (hatch/image/mesh), so
every INSERT of that block reflects the edits immediately.
REFCLOSE DISCARD removes the temp entities without changing the block.
Non-uniform-scale inserts are rejected with an error message.
RefEditSession is stored on DocumentTab; undo snapshots bracket the
begin and close operations.

- attedit.rs: AtteditCommand picks an INSERT entity then iterates through
each attribute tag prompting for a new value (Enter keeps existing)
- attedit_pending_handle() / attedit_set_attrs() trait methods inject
attribute data into the command after entity-pick (avoids document access
in the command itself)
- cmd_result.rs: NeedPoint handler injects attr data; ReplaceEntity detects
the __ATTEDIT__ sentinel and calls apply_attedit() on the document
- apply_attedit() encodes tag/value pairs as __ATTEDIT__tag\x01val\x02...
- ROADMAP.md: ATTEDIT marked ✅

- splinedit.rs: SplineditCommand picks a spline (entity-pick phase) then
accepts CLOSE/OPEN/REVERSE/EXIT sub-commands via text input
- apply_spline_op() mutates the spline in the document directly, with knot
vector regeneration via generate_clamped_knots()
- Sentinel XLine trick: ReplaceEntity with a magic __SPLINEDIT_* layer name
is intercepted in cmd_result.rs before erasing the original entity
- Control-point dragging already works via the existing grip editing system
- ROADMAP.md: SPLINEDIT marked ✅

Add shared spline_ops module with:
- spline_to_bspline / bspline_to_spline: acadrust ↔ truck BSplineCurve conversion
- spline_sample_xy: sample DXF-XY projection at N+1 points with parameters
- spline_nearest_t: nearest-parameter search via coarse+bisection
- spline_pts_wire: world-space wire points for WireModel preview
TRIM: Spline entities can now be used as cutting boundaries (Geo::Spline
sampled into polyline segments) and as entities being trimmed; uses
BSplineCurve::cut() to produce surviving pieces.
EXTEND: extend_spline() shoots a tangent ray from the nearest endpoint
and appends a control point at the first boundary hit.
OFFSET: offset_spline() offsets each sample point along the local
perpendicular normal and rebuilds a new spline from the offset control pts.
BREAK: break_spline() uses spline_nearest_t() + BSplineCurve::cut() to
split the spline at one or two click points.
LENGTHEN: lengthen_spline() uses numerical arc-length integration +
bisection to cut the spline at the parameter corresponding to the new
requested length.

Replaced the simplified MOVE-based STRETCH with a real crossing-window
implementation. Workflow: pick two crossing-window corners, then base+target
points. Only vertices/endpoints inside the window are translated:
- Line: moves start/end independently
- LwPolyline/Polyline: moves individual vertices inside window
- Arc/Circle/Ellipse: moves whole entity if center is inside
- Insert/Text/MText: moves if insertion point is inside

3-step interactive flow:
1. Entity pick (first break point recorded at click location)

3. Second break point → CmdResult::BreakEntity applied in cmd_result
Geometry:
- Line: project p1/p2 onto line parameter space → two line fragments
