- layouts.json: append the 6 missing ops (CreateDimensionRadius/Diameter/Angular,
CreateAttributeDefinition, CreateTable, CreateDimensionAngular2Ln); regenerate
binding_schema.json + api_reference.md wire vocabulary (all 28 ops).
- Helix bounds: bound the evaluated spline control polygon (was a degenerate
single-start-point AABB).
- points_aabb: empty -> Geometry::Empty('entity has no points to bound'), not
UnknownId (the entity exists; don't misclassify as stale/deleted).
- mass_properties: accuracy-first fine tessellation + graceful degradation to the
approximate meshes.metrics value when the cold-tess budget is exhausted (large
distinct-solid batches no longer hard-fail).
- IMPLEMENTATION.md: Volume/Centroid rows + accuracy paragraph + test count (618)
consistent with the final design.
- 618 host lib + 8 crate + 3 consistency green.
- mass_properties: query path now uses fine mesh_body(0.1, 1e-4) for near-analytic
volume/centroid; the render-mesh metrics cache (coarse display LOD) no longer
shadows query accuracy. Memoized per (handle, epoch); cold-tess budget kept.
- IMPLEMENTATION.md: accuracy item done.
- Test accurate_volume_centroid_sphere_and_cube (sphere within 0.5% of 4/3*pi*r^3,
centroid at centre, cube exact) -> 617 host lib green.

Fixes#1021
Switching to a Layout re-tessellated the whole model — `memo_miss=186455`,
2034 ms — to arrive at geometry identical to what was already in the memo.
The only thing that differed was colour.
`local_wires_for` already knows this: it stores the raw colour and drops
its background argument with `let _ = bg_color;`, noting that
`Batches::finalize` applies `adapt_to_bg` last, "so the cache no longer
has to rebuild on BACKGROUND / layout-switch". The tessellation memo's
guard had not been told, and still mixed the background in, so every
entry was discarded on a switch.
`finalize` now records what its colour resolution consumed — the raw
colour, the raw glyph colours, and the three flags it branches on — as
`WireModel::bg_adapt`, and `resolve_colors_for_bg` replays it for another
background. The guard drops the background, so a memo entry serves any
layout.
The resolution recomputes from the recorded raw colour rather than from
the resolved one, which makes it idempotent and therefore safe over a set
that mixes memo hits with freshly tessellated misses. Re-adapting the
resolved colour would not be safe: `adapt_to_bg` snaps a near-white colour
to pure black on a light background, and pure black comes back pure
*white* on a dark one, losing the tint. A test pins that asymmetry so the
raw colour is not optimised away later.
The contract is tested against the real `finalize` rather than a copy of
its logic: for every background pair, building under one and resolving for
the other lands exactly where building under the other would have.
`bg_adapt` is `None` for wires built anywhere else, and the resolution
skips them, so nothing outside the block cache changes colour. It is also
`None` when the resolution would be a no-op — a preserved colour with no
canvas fill looks the same under every background — which keeps the common
case at no cost.
Ordering is unchanged: the pass runs inside the builder, before
`append_scene_markers` and `apply_refedit_fade`, both of which have their
own separate background dependency.
`wires-build` gains `colors=` so the pass has a number of its own.

Switching to a Layout stops the main thread long enough that the
compositor decides the application has stopped responding and offers to
kill it. The switch itself is not the problem — `layout-switch` reports
about 10 ms — it is the frame after it, which rebuilds the whole wire set.
That frame now has a cheap one in front of it. `layout_settling` is set
when the switch takes, and while it holds, the viewport is replaced by a
centered "Preparing layout…" on the canvas background. No shader widget
means no scene primitive, so `prepare` has nothing to do and the frame
costs nothing. A `window::frames` subscription clears the flag, which is
the guarantee this needs: that callback runs once a frame has actually
been presented, so the notice is on screen and the compositor has been
answered before the expensive frame starts.
The deferral is of the *frame*, not the switch. Two callers depend on the
switch having completed when it returns — one calls `fit_all` immediately
after, another compares `current_layout` — so deferring the switch itself
would have broken both.
This restarts the compositor's timer immediately before the slow frame and
replaces a stale window with something that says what is happening. It
does not make the slow frame fast: if the rebuild still exceeds the
compositor's timeout the dialog can return, and the durable fix is the
2 s `memo_miss` behind it, which is a separate change.
Only `en-US` is validated against at build time; Greek is filled in too
since it is in use here, and the rest fall back until translated.

`view-detail` located the first paper frame's cost precisely: 7826.9 of
7832.8 ms in `grid`. Once, on the first frame after a layout switch —
every other frame in a 2769-frame session reports it at 0.0.
That is the largest single cost in a layout switch, larger than the model
re-tessellation and the arena rebuild combined, and it is not geometry
work at all. `grid_overlay` itself only wraps a canvas; `grid_segments`
runs later, in `draw`. So the time is in `grid_views` or in the per-view
parameter build, and reading the two does not settle which: both reach
helpers that can fall back to a full document walk, and neither obviously
fires for this drawing.
`grid-detail views= params= bg= n=` splits it, and reports only when the
block costs at least a millisecond so the quiet frames stay quiet.

The first Model→Layout switch costs ~9.2 s, and the largest single piece
of it is `view` at 5810 ms — iced widget-tree construction, not the scene.
The scene work that follows it in `prepare` (two `wires-build` calls plus
`frame-prepare`) accounts for 3377 ms, and the log's ordering shows the
two are sequential, not nested: `view` prints before any of them.
`view` being one number could not say which part of a 1950-line
`view_main` that is. It now reports eight sections — viewport_3d,
model_input, grid, selection_overlay, viewport_mouse, viewport_stack,
active_vp_rect, chrome — plus the preamble as `head`.
The marks go through a closure over a `RefCell` rather than one binding
per section: two of the sections sit inside a nested block, where
per-section bindings are out of scope by the time the report runs.

Reuse the application library from the binary entry point instead of compiling the module tree twice. Keep desktop-only transports and caches out of web builds, remove unused test code, and check executable targets in CI.
The first hover over the canvas after opening a large drawing froze the
UI for a second:
hover-detail query=0.2 handles=986.1 ... candidates=253
hover-dwell 986.6ms
`interaction_handle_index` and the insert-hatch map it reads are built
lazily, and first use is that hover. Neither can move to the loader
thread: they read `hatches`, `meshes` and `block_meshes`, which are
installed on the real `Scene` only after the loader has finished.
Build them at the end of the open instead, where the user is already
waiting. This does not make the work cheaper -- open grows by roughly the
second the hover used to cost -- but a second inside an operation that is
already seconds long reads very differently from a second-long freeze on
a mouse move.
