ACAD_SURFACE entities now load and render. Their NURBS faces are
tessellated by building a truck BSplineSurface from the ACIS `spline-surface`
control net and knot vectors, then sampling its parametric grid — reusing the
same NURBS kernel the Model tab already builds on. Analytic faces
(plane/cone/sphere/torus) continue through the existing tessellator.
- New spline_tess.rs: parse the ACIS `nubs` block (degrees, knots with the
clamped end-multiplicity fix, control grid) into a truck BSplineSurface and
mesh it.
- tessellate_surface + Surface wired through the mesh-build, fallback-wire,
and entity-classification paths.
- Bump acadrust to the commit that adds the Surface entity.

Dimension text position ignored the style: the renderer returned the
saved text_middle_point whenever it was non-zero, which it always is for
app-created dims, so DIMTAD ("text over the dimension line" / ISO) and
friends had no effect — text could only be moved by grips.
Use the new acadrust text_user_positioned flag: when the text wasn't
user-placed, compute the position from the style (DIMTAD/DIMTVP/DIMJUST)
anchored on the dimension line (definition_point); when it was (grip drag
or properties edit, both now set the flag), keep the saved point.
Imported drawings keep their fidelity via the flag round-tripping through
DXF/DWG.
Also fixes linear/aligned text anchoring at the measured midpoint instead
of the actual dimension line.

Binary (SAB/ASM) solids no longer collapse every vertex to the origin,
so 3D solids from AutoCAD 2013+ render with real geometry.

Picks up the AC18 section-name fix (cut at first null), so DWGs whose
writer left garbage after the name terminator load their entities
instead of opening with zero. Also rolls in the intervening upstream

Hatches inside blocks (xref_Plan-Sade) drew some boundary arcs as their
near-full-circle complement, covering huge areas — in the pattern clip
when rendered through the INSERT, and in both pattern and boundary wires
after EXPLODE.
Root cause (acadrust 64efaf8): the stored sweep of a boundary arc is
always forward and AutoCAD encodes a wrap through 0 by writing the end
angle ABOVE 2π (5.81 → 6.64 for a 0.83 rad arc). transform_hatch
normalized angles into [0, 2π), turning such arcs into their 5.46 rad
complement on ANY insert pass-through — even a pure translation, which
is why the same hatch looked fine outside the block. The fix transforms
only the start angle and carries the stored sweep over unchanged
(invariant under rotation and mirror); RAW vs exploded edge angles are
now bit-identical on the reporting file.

Hatches inside mirrored INSERTs (x_scale = -1, e.g. the *U blocks in
xref_Plan-Sade) drew some boundary arcs swept the wrong way, covering
huge complementary regions — in the pattern clip before EXPLODE, and in
both pattern and boundary wires after (the exploded entity bakes the
broken angles).
Root cause was in acadrust's transform_hatch, not the renderer: DXF
stores CW (ccw=false) boundary-arc angles MIRRORED (verified against
AutoCAD output by endpoint continuity — mirrored interpretation gives
Δ=0.0 against adjacent edges), and the transform stored geometric angles
after flipping the direction flag. The legacy (TAU-θ) sampling flip in
arc_signed_span is exactly right for file data and stays; its comment now
records the verification so the convention isn't "fixed" away again.

Picks up the fork's merge of upstream acadrust (geodata decode, DXF
roundtrip newline sanitization, DWG alignment) on top of the current
table/multileader style work.

Bump acadrust to pick up the new $CTABLESTYLE / $CMLEADERSTYLE header
variables, then on load seed the ribbon's active table style and the
tab's active multileader style from the document header so the ✓ marks
the style the file actually declares (DXF). Set Current writes the header
field as the round-trip source of truth, and the style-manager staging
snapshot now covers it. sync_ribbon_styles honours the active table style
instead of always falling back to the first one.
DWG still leaves these at "Standard" until acadrust parses them from the
binary header.

Phase 4.1. Handle / u64 keys dominate the hot maps (block_defn,
hatch / image / mesh caches, draw-depth map, viewport wire caches);
the default SipHash is wasted work on integer keys. Alias the std
types to rustc_hash::FxHashMap / FxHashSet crate-wide so every map and
set — including the cross-module draw-depth map shared between scene
and the GPU pipelines — uses the faster hasher consistently.
Mechanical: no behavioural change. Constructors moved from ::new() to
::default() (Fx variants carry no RandomState). Build + 13 tests green.

Read the model-space annotation scale from the standard CANNOSCALE /
CANNOSCALEVALUE header variables instead of a user-variable hack, and
populate both the status-bar scale picker and the viewport Scale
property purely from the drawing's ACAD_SCALELIST — no built-in
fallback set. Xref-derived scales (`_XREF` suffix, `name|` prefix)
are filtered out so only the host drawing's own scales appear.
Bumps the patched acadrust to the commit that adds CANNOSCALE/
CANNOSCALEVALUE read/write.

vtkio (via truck-meshalgo → xz2 → lzma-sys) linked the system liblzma
dynamically, baking a Homebrew path (/opt/homebrew/.../liblzma.5.dylib)
into the macOS binary. The .app then crashed on launch on any Mac
without that exact library. Enable lzma-sys's `static` feature so
liblzma is compiled from the bundled source into the binary, making it
self-contained on every platform (verified: no dynamic liblzma link).

Creating a new MLeader/Table/MLine style (and a new PlotSettings) pulled
the document's next handle without advancing the counter, so two records
created in one session collided on the same handle and the second

Each model-space tile now carries its own visual style instead of one
global mode shared by every pane:
- ModelTile gains a `render_mode`; the active tile renders with the live
picker mode, inactive tiles keep their stored style, so changing one
tile no longer changes the others. Split inherits the source style.
- SetRenderMode writes only the active tile; switching the active tile
mirrors its style back into the tab (picker + live render).
- Persisted through the *Active VPORT entries (acadrust now round-trips
the render mode via DXF code 281 / DWG RC 281), restored on open for
both tiled and single-tile model layouts.
- Bump acadrust to pick up the VPORT render-mode field.

Rename the Home tab to "Draw" and add a Model tab beside it with two
groups:
- Model: BOX / CYLINDER / CONE / SPHERE / WEDGE / TORUS, placed with a
footprint + height. Each is built as a real ACIS Solid3D (acadrust
primitive builders) plus a truck B-rep, tessellated into the shaded
mesh pipeline, with edge wires for picking + wireframe.
- Design: UNION / SUBTRACT / INTERSECT via truck-shapeops.
A session-only Scene.model_solids cache holds each solid's truck B-rep
so the boolean tools can combine and chain them. Supersedes the old
command-line BOX/SPHERE/CYLINDER (insert::solid3d_cmds keeps EXTRUDE/
REVOLVE/SWEEP/LOFT).
Known limitations: booleans need solids created this session; curved
ACIS primitives render in-session but not after reload (the SAT
tessellator handles only planar caps); geometry assumes world_offset 0.

Type directly into the rendered MText preview: click to position the
caret, insert/delete, Enter for a new line, Space for a literal space,
and arrow keys to move. The caret blinks when idle.
Keep the trailing empty paragraph in the editor so the caret appears on a
fresh line immediately after Enter, before any typing. parse_mtext_paragraphs
split into a _ex variant; layout_mtext skips the blank-edge trim when
emitting glyph boxes.

Type-as-you-go suggestion popup above the input that filters known
command names by substring (so `LEADER` surfaces both LEADER and
MLEADER). Up / Down navigates the list, Enter dispatches the
highlighted entry, clicking a row dispatches directly. Esc on a
non-empty input clears the buffer instead of escalating to
command-cancel.
The name corpus comes from `inventory::submit!` blocks placed next
to each `CadCommand` impl rather than a hand-maintained static list.
Adding a new interactive command means dropping one `inventory::submit!`
line in its own module file — the autocomplete picks it up at the
next compile. 98 submissions seeded across 60 module files;
`command::all_registered_command_names()` flattens them at runtime.
One-shot dispatch arms in `app/commands.rs` (NEW, OPEN, SAVE, UNDO,
…) don't have a `CadCommand` impl and are therefore absent from
autocomplete by design.

acadrust's DWG reader read the wipeout/raster-image clip boundary
points only to advance the bit cursor and then discarded them, so every
wipeout fell back to `Wipeout::new()`'s default placeholder rectangle
(`-0.5..0.5`). For files that store the real polygon mask in clip
vertices (anteen.dwg's `DIMBLOCK` style: u_vector ≈ 643k, size = (1, 1),
clip polygon ~0.0016×0.0033 in pixel space), the wipeout rendered at the
full image bbox — hundreds of thousands of units wide — instead of the
intended ~1000×2000 mask.
Pinned to the new `fix/wipeout-clip-vertices` acadrust branch (carries
the upstream parser fix). On the H7CAD side, the polygon mapping now
follows the DXF convention:
x_off = (clip.x + size.x/2) × u_vec
y_off = (size.y/2 − clip.y) × v_vec (image-Y points down)
…in `wipeout_boundary_2d` (fill), `Wipeout::to_truck` (border line),
and `Wipeout::grips` (vertex handles) so all three stay in sync. The
fill path also explicitly closes the polygon loop — without it the GPU
`in_polygon` ray-cast skipped the v(n-1)→v(0) edge and the solid mask
bled far past the boundary.

- .github/workflows/release.yml: remove the build-flatpak job; matrix-
add macOS (arm64 + x86_64) that builds H7CAD.app by hand, renders
.icns from assets/logo.svg via librsvg + iconutil, and packages a
UDZO .dmg. AppImage path updated to packaging/H7CAD.desktop.
- packaging/H7CAD.desktop: moved out of flatpak/ so the AppImage job
doesn't depend on a Flatpak layout.
- packaging/Info.plist: macOS bundle template; __VERSION__ swapped
for the release tag at build time.
- flatpak/: deleted (manifests, metainfo, desktop, builder cache).
- src/main.rs: `#![cfg_attr(all(windows, not(debug_assertions)),
windows_subsystem = "windows")]` so the Windows GUI binary no
longer spawns a console window alongside it (debug builds keep
the console for log output).
- README: add macOS install section, document Gatekeeper / SmartScreen
on first launch since the binaries are unsigned.
Bump to 0.3.5.

upstream/main, [patch.crates-io] points at the fork branch carrying
that commit; the comment in Cargo.toml notes the revert.
