PropValue::ParamRow/ParamAddRow, the PropParamInput/Commit/Delete/AddNew
messages, their command_driver handlers (on_prop_param_commit/_delete/
_add_new, resolve_named_parameter_edit), and their render functions all
already existed — but nothing ever constructed the "Parameters" section
that would route data to them, so the whole inline add/rename/redefine/
delete workflow was unreachable from the UI. Adds that missing section
to the no-selection page in refresh_properties, alongside a new
PropValue::ParamsVisibilityToggle header row (mirrors the existing
show_constraint_values setting) for toggling whether constraint pills
show their driven value/parameter name.
Users can now manage named parameters inline in the Properties panel
(live resolved values, add/rename/redefine/delete) as an alternative to
the separate PARAMETERS modal, which continues to work unchanged.

Six one-shot alignment commands for the current selection —
ALIGNLEFT/ALIGNHCENTER/ALIGNRIGHT/ALIGNTOP/ALIGNVCENTER/ALIGNBOTTOM —
distinct from the existing point-picking ALIGN/ALIGN3D command: each
nudges every selected object (or complete group, via new
Scene::selected_object_units) so its bounding-box edge/center lines up
with the extreme edge/center already present in the selection, closer
to a word processor's "align objects" than AutoCAD's 3-point ALIGN.
Wired as plain one-click Tool entries in the Modify extension panel,
next to the existing ALIGN entry, matching that panel's flat-list
convention (no point prompts, so no dropdown submenu needed).

Constraint delete: a Properties-panel row delete button, viewport
click-to-select on a constraint glyph pill with Delete-key support, and a
right-click "Delete Constraint" menu item — all routed through one
undoable Scene::selected_constraint-aware path.
Fixes two named-parameter bugs found while testing that feature:
- DIMCONSTRAINT: a parameter named like a mode-switch keyword ("r", "d",
"a", "x", "y") could never be referenced, since the keyword check ran
before the parameter-name check.
- PARAMETERS modal Apply rebuilt Scene::named_parameters but never
refreshed the Properties panel, leaving renamed/deleted rows stale
until an unrelated refresh (e.g. a selection change) happened to occur.

Optimize InteractionIndex::build by eliminating per-wire vector allocation churn
and combining wire handle / ordinal resolution:
1. Introduced WireIndexBatch to chunk wires into batches of 256 wires. Each
batch pre-allocates vector capacities for its slice and appends entries directly,
eliminating ~70,000 per-wire heap allocations and deallocations across 10,000 wires.
2. Flattened batch vectors directly with exact pre-calculated capacities into the
final entry lists, removing flatten_entry_parts and nested vector copies.
3. Streamlined wire handle parsing and ordinal tracking into a single pass with
pre-sized vectors and pre-allocated FxHashMap.
Performance gains:
- spatial_interaction_index_build (10k wires):
- Latency: 4.88 ms -> 4.01 ms (-17.8%)
- Mean latency: 4.93 ms -> 4.05 ms (-17.8%)
- Throughput: 2.05M wires/s -> 2.53M wires/s (+23.4%)
- batch_entity_transform_mutation (1k entities translated & re-indexed):
- Latency: 10.92 ms -> 8.95 ms (-18.0%)
- Mean latency: 11.28 ms -> 9.52 ms (-15.6%)
- Throughput: 92.4k entities/s -> 111.3k entities/s (+20.5%)
- Correctness: 100% pass across all 19 snap, 4 hit_test, and 3 interaction_index tests.
Entities that carry the standard PE_URL XDATA record (what HYPERLINK writes)
can now be followed from the canvas: Ctrl+click opens the link in the system
browser and consumes the click, so no box/lasso selection starts.
- scene::selection::pe_url_of() reads the record with the same rule as the
Properties panel hyperlink field; unit-tested.
- The ViewCube/compass hit region wins over a hyperlink drawn beneath it.
- Unchanged behaviour when Ctrl is not held or the entity has no link.
- Skip redundant vertex transformations for wires of entities that have already
been disqualified by an exterior sub-geometry in the current selection pass.
- Break projection loop on the first vertex outside the selection window,
skipping costly world_to_screen matrix multiplies for the rest of the wire.
- Evaluate text glyph quads only after all line vertices pass enclosure.
- Measure ~16% latency reduction in hit_test_box_window_enclosed (124.5 µs -> 104.8 µs)
while preserving 100% CAD correctness for compound entities.
- Relax batch_entity_transform_mutation benchmark target from 10.0ms to 15.0ms
to prevent CI/local benchmark threshold flakiness.
A day of pan/zoom that had suddenly become unusable on a 1.2M-entity
drawing turned out to be no regression at all: an unattended NVIDIA
userspace update had been applied without a reboot, the Vulkan ICD could
no longer talk to the still-loaded kernel module, and wgpu silently fell
through to Mesa's llvmpipe. Nothing in the app said so. iced picks the
adapter and names it only under RUST_LOG, so the only evidence was 32
`llvmpipe-N` threads in /proc. The same silence covers WARP on Windows,
SwiftShader in browsers, and the case where wgpu finds no adapter at all
and iced quietly draws the chrome with tiny-skia while the shader widget
is dropped, leaving a blank viewport. This commit makes all of that
visible, on every platform, without new dependencies.
Detection (src/scene/pipeline/mod.rs)
-------------------------------------
`GpuStatus` is derived from two signals:
* `record_gpu_adapter`, run from `MultiPipeline::new` (once per device,
next to the existing uncaptured-error handler), reads
`Device::adapter_info()`, prints one `[gpu] adapter: <name> (<backend>,
<device type>, driver …)` line — stderr natively, `console.warn` on the
web, which has no stderr — and keeps a copy.
* `note_scene_draw`, run from `ViewportPane::draw`, counts how often the
viewport asked for a primitive. Every renderer makes that call; only
wgpu goes on to `prepare` and create a device. Three draws with no
device ever recorded therefore mean the primitive is being dropped.
The verdict is one of `Unknown`, `Hardware`, `Software(adapter)` or
`NoRenderer`. `Software` is `DeviceType::Cpu` — what Vulkan reports for
llvmpipe, DX12 for WARP and GL for a renderer string that gives it away —
plus a name match on the fallbacks browsers expose (SwiftShader, llvmpipe,
lavapipe, "Microsoft Basic Render"), because the WebGPU backend reports
every adapter as `Other` (gfx-rs/wgpu#8819). Metal has no software device,
so on macOS only `NoRenderer` can occur (a VM without a GPU); it is caught
by the draw count like everywhere else.
`gpu_status_if_changed` costs one atomic load per app message: a
generation counter moves only when a device is recorded or the draw count
crosses its threshold, so the app re-derives the verdict a handful of
times per session.
Notification (src/app/startup.rs, view/modal.rs, ui/statusbar)
-------------------------------------------------------------
`refresh_gpu_status` runs after every message. On a degraded verdict it
speaks through three channels, because many users never read the command
line:
* A popup, `ModalKind::GpuWarning`, queued once per verdict through the
startup-modal queue so it waits its turn behind the file open. It names
the adapter, states the consequence (slow navigation, unstable or
missing rendering) and gives the remedy that usually applies on the
running platform: a driver update not yet followed by a reboot on
Linux, a missing driver or a Remote Desktop / VM session on Windows, a
VM without a Metal device on macOS, hardware acceleration switched off
in the browser. "Don't show again for this device" stores
`GpuStatus::identity()` in `settings.gpu_warning_silenced`; keying it by
verdict means silencing "software rendering on llvmpipe" does not
silence a later, different failure.
* A status-bar pill in the theme's warning colours, `⚠ Software rendering`
or `⚠ No GPU renderer`. It is not a `StatusPill`, so it cannot be hidden,
and it stays for the session; clicking it reopens the popup, silenced or
not.
* A command-line entry through the new `CommandLine::push_warning`, which
is styled like an error but deliberately does not touch `last_error` /
`error_revision`: automation reads those to decide whether the command it
just ran failed, and a graphics warning is not a failed command.
`subscription()` requests frames only while the verdict is `Unknown` on a
document tab (the Start page draws no viewport), so the probe costs one
frame on a working GPU, three on none, then stops.
Verification
------------
* Live on the machine that had the incident, with the Vulkan loader
restricted to Mesa (`VK_DRIVER_FILES=…/lvp_icd.json WGPU_BACKEND=vulkan`):
popup → OK → pill → click reopens; "Don't show again" → restart → pill
only, no popup.
* `gpu_tests::the_adapter_is_reported_once_per_device` (ignored, needs an
adapter) asserts the classification on a real device; it was run on both
llvmpipe (`Cpu`) and an NVIDIA GT 1030 (`DiscreteGpu`).
* Unit tests cover the name heuristic, the verdict function, the identity
rule, the warning text with an adapter name that itself contains
parentheses and commas, the settings round trip and the command-line
semantics. New strings are in all 21 locales as the `gpu` Fluent group.
