Vertices now carry the low residual alongside the high half all the way
to the GPU: tessellation splits the offset-relative f64 coordinate into
(high, low) f32 (TruckTessResult::Lines/Point, the Text path, Lines /
SegmentedLines, and the block-cache instance transform), WireModel and
the block batch carry a paired points_low buffer, WireInstance gains
pos_a_low/pos_b_low (locations 10/11), and wire.wgsl reconstructs
rel = (pos_high - eye_high) + (pos_low - eye_low).
This is the piece the camera-only RTE was missing: at UTM-scale
coordinates the single-f32 vertex was quantized to ~0.5 m, so it snapped
each time the eye crossed an f32 boundary on pan. With the low half the
position is exact and the cross-drawing-paste jitter is gone.

Gate target-specific code so neither build warns about the other's items:
native-only helpers (view, window icon, file dialogs, file association, plugin
host/guard/registry, self-update) are cfg'd to non-wasm; the wasm-only font
fallback (script_of / cjk_lang / request) is cfg'd to wasm. Drop an unused mut,
allow the few genuinely-conditional dead items (mesh_click_hit, GPU layout
helpers, parity stubs), and gate the embedded PlotSettings-unrelated dead
constants. Both targets now build clean (only the unavoidable nom/quick-xml
future-incompat dependency notice remains).

wasm32 has no threads, so rayon's global pool would panic at runtime.
Add `crate::par::prelude`: native re-exports `rayon::prelude`, wasm
provides sequential `std`-iterator equivalents (par_iter / into_par_iter
/ flat_map_iter over slices, Vec, HashMap, HashSet). All call sites now
`use crate::par::prelude::*;` instead of rayon directly.
- wire_gpu's rayon `reduce` (2-arg, no std equivalent) is cfg-split to
a sequential flat_map concat on wasm.
- rayon moves to a non-wasm target dependency.
Native still runs in parallel; all 75 tests pass. wasm bin compiles.

Move the 30 flat modules under src/scene/ into six folders by role:
convert (entity→geometry), text (fonts/shaping), model (render models),
pick (hit-test/selection/grips/xclip), view (camera/transform/render),
cache (block + property caches). pipeline/ is unchanged.
Full path migration — all `scene::X` references become
`scene::<group>::X`, no compatibility re-exports. render.rs items that
were `pub(super)` (parent was scene) become `pub(in crate::scene)` to
keep their original scene-wide visibility.
No behavior change; build and tests are green.

Follow-up to 3.3. The selection xray pass still built one buffer + one
draw call per selected wire, so select-all over a large drawing issued a
draw per entity. That pass applies neither scissor nor mesh-edge skip, so
all selected wires merge into one order-preserving run via from_run.
Removes the now-dead WireGpu::new / build per-wire constructors.

Phase 3.3. upload_wires built one GPU instance buffer + one draw call per
WireModel — tens of thousands on a large drawing, a major per-frame CPU /
driver cost. Merge maximal runs of consecutive wires that share scissor +
mesh-edge state into one concatenated instance buffer each (WireGpu::
from_run); the existing draw loop then issues a single draw per run. A 2D
model (uniform None scissor, no mesh edges) collapses to one buffer + one
draw.
Runs are consecutive, never globally regrouped, so the sorted wire order
is preserved exactly — depth-biased overlap and alpha blending both
resolve in submission order, so the image is unchanged. from_run
guarantees instance order (index-ordered collect + sequential flatten).
The WireInstance layout, shader, scissor projection and draw loop are
untouched; only buffer packing changed. Selection overlay stays per-wire.

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.

The rendered MText preview is now an editable surface: it shows a text caret,
click to position it between glyphs, and type/Backspace/Delete/Enter to edit.
Left/Right arrows move the caret; drag-selection + toolbar formatting still
work and typing replaces a selection.
Keystrokes are routed by mapping visible-character offsets to byte spans in
the value (raw newlines count as paragraph breaks, matching the layout). While
the preview is open the command line releases its on_input so typed glyphs
reach the preview instead, and the caret starts at the end of the text so
typing works without a click first.

DRAWORDER now affects rendering immediately (bump geometry epoch so the
sort cache rebuilds) and front/back anchor to the block's full effective
sort range instead of only existing table entries, so bring-to-front
actually lands on top. The render fallback sorts table-absent entities by
their own handle.
Draw order now applies across entity types, not just within a type. A
per-entity draw-order rank (SortEntitiesTable override or own handle,
ranked per block) is encoded as a small signed clip-z bias in the wire,
hatch, image, and 3DFACE pipelines. The shared LessEqual depth buffer then
orders fills, lines, rasters and 2D solids against each other regardless of
pass order — without touching model coordinates. 3D meshes keep real
geometric depth; wipeouts stay always-on-top.
Adds a Draw Order submenu to the viewport context menu (Bring to Front,
Send to Back, Bring Above/Send Under Object). The above/under items run an
interactive reference-object pick, then reorder the captured selection.

Step 4 (final) of the wire pipeline cold-open optimization plan. Color
shrinks from `[f32; 4]` (16 B) to `[u8; 4]` (4 B) and the vertex attribute
format flips to `Unorm8x4`; the GPU still hands the shader a `vec4<f32>`
in [0, 1], so wire.wgsl needs no change. 8-bit per channel is below
display precision.
Net: 76 B per instance, ~14 % smaller than the Step-3 instance layout and
~7.6× smaller than the pre-Step-3 per-vertex format. Wire upload memory
and PCIe bandwidth on cold open scale down accordingly.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Step 3 of the wire pipeline cold-open optimization plan — the biggest
single lever.
Each segment used to upload as 6 vertices × 96 B = 576 B with the segment
payload (pos_a/pos_b/color/half_width/distance/pattern_length/pat0/pat1)
duplicated across all six corners of the quad. Wire pipeline now uploads
one INSTANCE per segment (88 B) and the vertex shader derives `which_end`
and `side` from `@builtin(vertex_index)` against a 6-entry corner table.
Net effect on cold open: ~6.5× less wire vertex memory and PCIe upload,
plus a smaller Vec to allocate and copy on the CPU side.
Wire instance attributes also collapse distance_a / distance_b into a
single mix() inside the vertex shader, so per-segment distance still
interpolates correctly for the GPU-side linetype dash test.
Touches the wire, wire_xray, and face3d-edges draw passes.

Step 2 of the wire pipeline cold-open optimization plan. Extracts the
per-wire vertex expansion into a free function and drives it from
`from_batch` via `par_iter().map(...).reduce(...)`. Per-wire emission is
already independent (no shared state, no order coupling — `block_cache`
groups wires by style upstream), so the parallel-then-concatenate shape
is correctness-preserving.
Cold-open wire upload now scales with available cores; a drawing with
many short wires shows the biggest win. Also collapses two near-identical
emission loops (`from_batch`, `build`) into one shared helper.

Step 1 of the wire pipeline cold-open optimization plan. Replaces
`create_buffer_init` (intermediate staging-buffer memcpy) with a
`mapped_at_creation` buffer the build path writes into directly.
Cuts one alloc + one memcpy per wire buffer; on cold open with hundreds
of MB of wire data this shows up immediately as lower peak memory and
faster upload.
Guarded against size-0 buffers by allocating a single-vertex placeholder
when the wire is empty (the renderer already skips draws on vertex_count
below the per-segment minimum).

Each item below was gated by #[allow(dead_code)] and has zero callers
across src/ — none of them are part of any public API consumed by
external crates (this is a binary, not a library):
* modules/insert/underlay_frames.rs + edit_aliases.rs — toolbar stubs
whose `tool()` registrars were never wired into the ribbon; the
parent mod.rs inlines its own include_bytes! for the SVGs, so the
files were orphan dead weight.
* ui/snap_popup.rs:snap_marker_color — never called.
* ui/ribbon/mod.rs:last_dropdown_cmd — never called.
* ui/scale_popup.rs:anno_scale_for_label — never called.

Remove MAX_SEGS_PER_WIRE = 100_000 and MAX_TOTAL_SEGS = 3_000_000.
These were stop-gap GPU-memory guards that mutated visible output:
single complex entities were cut mid-geometry, and entire wires past
the 3M total were dropped by arrival order with no spatial awareness.
Either is worse than honestly drawing whatever the file contains —
truncated arcs and missing road segments look like bugs to the user,
not "we ran out of GPU memory."
The matching "Temporary Workarounds" section in
RENDERING_OPTIMIZATION.md goes with them. Per-entity LOD and
viewport culling (Phase 1 + 3.2 in the same doc) remain the right
long-term answer; until they land, prefer correctness over a soft
crash on pathological files.

Adds two-layer protection against large entities crashing the renderer:
- MAX_SEGS_PER_WIRE (100K): per-entity hard cap, excess segments truncated
- MAX_TOTAL_SEGS (3M): scene-level budget in upload_wires, excess wires skipped
Both limits log a warning to stderr when triggered.

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).

- fix: polyline arc center sign was inverted (- → +) causing arcs to render on the
wrong side in LwPolyline and Polyline2D
- fix: store glyph strokes in local space with f64 origin so world_offset subtraction
uses f64 precision; prevents blocky text at large UTM coordinates
- fix: Face3D fill darkened to 45% so edge wires are visually distinct from fill
- fix: wire batch vertex buffer chunked to 256 MB GPU limit (was panic on large files)
- fix: gpu_face3d_edges changed from Option<WireGpu> to Vec<WireGpu> to support chunks

3DFACE entities previously created one WireGpu buffer per entity,
resulting in N separate draw calls per frame. For files with large
triangle meshes this was the dominant GPU CPU overhead.
New pipeline:
- face3d.wgsl: simple flat-color vertex + fragment shader (MVP only,
no quad expansion, no pattern distance computation)
- Face3DGpu: batches ALL Face3D entities into a single TriangleList
buffer (6 vertices per face, per-vertex color) — 1 draw call
- WireGpu::from_batch: merges N Face3D edge wire models into one
quad-expanded buffer for edge rendering — 1 draw call
- split_face3d_wires: separates face3d from other wires at Primitive
build time via document handle lookup (O(N), once per epoch)
Hit-testing via WireModel (CPU) is unaffected — face3d wires remain
in entity_wires_arc() and hit_test_wires() as before.
Before: N 3DFACE → N draw calls, N × 96 B/vertex WireVertex
After: N 3DFACE → 2 draw calls (fill + edges), 28 B/vertex fill

Three root causes caused all geometry and UCS arrows to disappear:
1. TruckObject::Lines and TruckObject::Text variants returned world-space
f32 coordinates without applying world_offset, so fit_all() computed
bounds spanning from local space to UTM world space (~4 M m), placing
the camera impossibly far from all visible geometry.
2. Ray/XLine entities with unnormalized direction vectors (common in some
DXF exporters) produced astronomically large far-point coordinates
(up to 1e28) that overwhelmed the camera fit even after the offset fix.
Fixed by normalizing the direction vector before multiplying by
DISPLAY_EXTENT.
3. Origin-stuck corrupted entities (coordinates ≈ 0 in world space become
≈ -world_offset in local space) pulled the fit_all() bounds far from
the actual drawing. Fixed by computing local_extent_max from EXTMIN/EXTMAX
(10× safety margin) and skipping points outside that range in fit_all().
Additional hardening: wire_gpu.rs now skips ±inf segments (not just NaN),
and snap_pts/key_vertices in all TruckObject variants are offset-corrected.

Subtracts the DXF header extents centroid (world_offset) from all coordinates
in f64 BEFORE casting to f32. This eliminates the ~0.5 m ULP error that occurs
at 4,000,000 m UTM coordinates and caused geometry to disappear on zoom-out.
- Scene: adds world_offset field + compute_and_set_world_offset() method
- tessellate.rs: threads world_offset through all f64→f32 conversions
(legacy_geometry, dimension_geometry, solid_wire_fallback, multileader)
- truck_tess.rs: to_local() helper already in place from prior session
- mod.rs: tessellate_entity() and entity_aabb() apply world_offset
- update.rs: compute_and_set_world_offset() called after doc load
- cmd_result.rs / solid3d_cmds.rs: pass correct offset to truck tessellators

Selected wires are now visible through occluding objects. A second
wire_xray pipeline (depth_compare=Greater, depth_write_enabled=false)
renders 25%-alpha ghost copies of selected wires only where they are
behind the depth buffer, leaving fully-visible portions at full glow
brightness unchanged.
