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.

build_primitive ran split_face3d_wires every frame — for each wire a
string-parse + document handle lookup + clone, to separate Face3D wires
from the rest — even when a pan had just reused the tessellation. The
split is content-only, so memoize it by the Model-tile wire content id:
a pan-reuse (same id) reuses the split, and the common no-overlay frame
returns the cached `other` Arc with zero clone. Preview/interim frames
clone once to append. Non-tile paths split inline as before.
Completes the cheap-pan path: a pure pan now reuses the CPU
tessellation, the Face3D split, and the GPU wire upload — only the
view_proj uniform and per-frame scissors recompute.

Phase 3.2 (wire pan path). Wire vertex buffers are world-space, so a
camera move changes only the view_proj uniform (uploaded every frame),
never the wire data — yet upload_wires re-ran on every camera_generation
tick, re-packing vertices and re-writing the GPU buffer on each pan.
Stamp every Model-tile re-tessellation with a monotonic content id
(WIRE_CONTENT_GEN), reused when a pan reuses the tessellation. The
pipeline records the resident buffer's id and skips upload_wires when the
incoming id matches. The gate is pulled out of the (epoch, camera_gen)
block so a preview/interim wire change still uploads even with a static
camera; non-tile paths and overlay frames force a fresh id, preserving
current behaviour. Monotonic id sidesteps the ABA hazard a freed/realloc'd
Arc pointer would carry.
Pairs with the pan tessellation reuse: a pan now skips both the CPU
re-tessellation and the GPU wire upload.

Phase 3.1 (partial — pan). The Model-tile wire cache keyed on the exact
camera hash, so every pan re-tessellated the whole tile even though pan
changes neither the curve tol nor the culled set (beyond a shift). Re-key
on (geometry_epoch, pan_invariant_hash, tessellated_region):
- pan_invariant_hash covers rotation + wpp (tol) but excludes the pan
target, so a pure pan keeps it stable;
- the wires were culled to a 1.25x-margin region, recorded with the entry;
- a hit now also requires the tile's current visible rect to still fit
inside that region, guaranteeing every on-screen wire is present.
Result: panning within the existing margin reuses the tessellation (tess
ms -> ~0 on the PERF HUD) with no missing geometry. Zoom, orbit and edits
change the signature/epoch and rebuild as before; the cull margin is
unchanged so miss cost — and zoom behaviour — is identical. GPU still
re-uploads per camera_generation (diff upload is Phase 3.2).

Extends Phase 2.1. compute_block_aabbs resolved each defn's union AABB
serially via defn_aabb_recursive, which only reads the finished defns map
and re-walks shared nested defns with no memoization — real cost on
block-heavy drawings. Split into a parallel read phase (per-name resolves
fan out over rayon) and a serial write-back phase. BlockCache is Sync, so
sharing &self across the read phase is sound.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Phase 5.3 (CPU tessellation slice). Add a `PERF` command that toggles an
overlay on the active viewport showing the cost of the most recent wire
re-tessellation: ms, wire count, geometry epoch. Anchored top-left via
position_canvas_overlay.
Timing is captured at the wire-cache miss paths (model_tile_wires_arc,
paper_sheet_wires_arc) and stored in Cells on Scene, read directly by the
UI view (Scene is single-threaded / Rc-based, so build_primitive and view
share a thread). Reads ~0 ms on a warm cache, so it isolates the exact
work a miss costs — the slice 2.2 / 3.1 / 3.3 each move, making them
PR-to-PR comparable.
GPU upload/draw/GPU-wait spans (need wgpu timestamp queries) remain open.

Phase 3.1 (partial). set_hover_highlight bumped the geometry epoch on
every hover-target change, forcing a full model re-tessellation. The
hover handle is folded into the tessellation highlight set as
selected ∪ {hover}, so hovering an already-selected entity contributes
nothing — the effective set and every resulting WireModel are identical.
Guard the bump on the effective highlight contribution actually changing;
hovering over or between selected entities is now free. The field is
still updated so hit-test / UI state stays current.
The full camera/selection-from-tessellation cache split (3.1 / 2.2) is
left open: highlight colour is baked into WireModel.color across several
tessellation sites, so decoupling it needs running-app verification.

Phase 2.1. build_defn stores nested INSERTs as by-name references and
never expands them at build time, so each block defn depends only on the
read-only doc — the builds are independent, not topologically ordered as
the roadmap assumed. Replace the serial loop with a rayon
par_iter().collect(). render_style_for / tessellate already run under
rayon in build_derived_caches, so thread-safety is established.
compute_block_aabbs stays serial (resolves nested refs, cheap post-pass).
Cuts first-frame block tessellation on insert-heavy drawings.

Phase 5.2. Time each open phase — parse, purge, derived-cache build on
the loader thread, plus xref resolve on the UI thread — and emit a
breakdown line on open completion:
parse 1240ms · purge 80ms · caches 340ms · xref 60ms · total 1820ms
Makes open-time regressions (and the wins from 1.1 / 2.4) visible at a
glance. Timings ride back on DerivedCaches; total is wall time from the
Open click to post-xref.

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.

Phase 1.1: resolve_xrefs now purges corrupt entities inline as it
merges each xref and returns the dropped count, removing the second
full-document purge_corrupt_entities walk in the FileOpened handler.
Every xref-bearing open saves one O(N) entities() pass.
Phase 2.4: split compute_world_offset into offset_prep / offset_centroid
/ world_offset_from_centers; centroid accumulation now rides the existing
cache-handle walk in build_derived_caches. Two O(N) entity walks collapse
into one, with identical MSPACE-membership filtering preserved.

BOX, SPHERE, and CYLINDER build truck topology solids and tessellate
them into MeshModels stored alongside a Solid3D placeholder entity so
the GPU mesh pipeline renders them immediately.
EXTRUDE picks any closed 2D profile (Circle, LwPolyline, etc.),
attaches a planar face via try_attach_plane, and translational-sweeps
it (tsweep Face → Solid) along Z by the given height.
REVOLVE picks a profile, two axis points, and an angle (default 360°),
then rotational-sweeps the wire (rsweep) around the axis.
Three new CmdResult variants drive the operations:
CommitSolid3D, ExtrudeEntity, RevolveEntity.
Scene::layer_color() added to retrieve the active layer's RGBA color.

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.

Grid snap (F9):
• snap spacing now tracks the visible grid zoom level — computed via
compute_grid_step() (same adaptive pow-of-5 logic as draw_grid),
updated on every ViewportMove so zooming in/out keeps snap aligned
with the grid lines on screen
Polar tracking (F10):
• configurable angle increment stored in polar_increment_deg (default 45°)
• right-click the POLAR pill to cycle through 15 → 30 → 45 → 90°
• pill label shows current angle ("POLAR 45°")
• visual guide line: while drawing with polar on, a dashed cyan line is
drawn from last_point along the snapped direction across the viewport
• SetPolarAngle message + handler; all polar_constrain() calls use the
stored increment instead of the hardcoded 45°

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
