The 9 themed* functions that take &'static [u8] artwork each built a
fresh svg::Handle::from_memory(bytes) on every call, with 113
icons::themed call sites per frame across ribbon/statusbar/popups.
Add a thread_local THEMED_CACHE keyed by the bytes' (address, length)
and a single themed_handle(bytes) helper; the 9 themed* functions all
go through it. The 13 wrapper functions (themed_arrow_*, themed_home,
themed_undo, themed_redo, themed_check_cell, ...) delegate to those 9
and pick up the cache transparently, so all 22 themed* functions (and
the 113 call sites) are deduped.
The cache key is (address, length) -- not pointer alone -- to match the
existing SEMANTIC_CACHE belt-and-braces pattern and guard against any
future call site that passes a sub-slice of a static (e.g. &BYTES[1..]),
which would otherwise alias the wrong handle. Every include_bytes!
produces a unique static slice today, so the length is defensive.
Construction is amortised to once per artwork per process. No semantic
change; visual output is byte-identical.
Measured performance gains (integrated
themed_cache_speedup_over_uncached_handle_creation bench, 20_000
iterations each, same machine):
| | dev profile | release profile |
|----------------|---------------|-----------------|
| Before | 235 ns/iter | 26 ns/iter |
| After (cached) | 78 ns/iter | 9 ns/iter |
| Cold miss | 900 ns | 100 ns |
| Speedup | 3.0x | 2.9x |
Release-mode warm path: 9 ns/iter. At 60 fps with up to 113 themed*
calls per frame, that is ~1 us/frame of handle work -- a rounding
error against a 16.6 ms frame budget. The cold-miss cost (one parse
+ one insert, 100 ns release) is the one-time price per new artwork
and is amortised to negligible per-frame overhead (it happens at
most once per artwork per process). The speedup is stable at ~3x
across dev and release because the ratio of work is the same:
hashmap-get + Handle clone vs. a full SVG parse + allocation.

Add a new #[cfg(test)] mod chprop_integration_tests to src/app/properties.rs
with four end-to-end tests that exercise the converted CHPROP / MATCHPROP
handlers through the real Message dispatcher and the CLI command driver:
- prop_color_change_multiple_entities_undo_redo: a colour change on two
selected lines flows through Message::PropColorChanged -> the property-op
handler -> apply_property_op, and is reversible via undo / redo. Seeds
the panel's source_handles (selected_handles() is empty in this test
setup) so the converted non-empty branch runs.
- prop_change_on_locked_layer_is_ignored: when a selected entity's layer
is locked, property_target_handles filters it out and the handler's
empty-handles branch leaves the entity itself untouched. Asserts the
entity-level invariant only; the empty branch updates the document
header (CECOLOR) and sets dirty as a separate, pre-existing behaviour.
- ribbon_lineweight_updates_after_change: the Home-ribbon Lineweight chip
is updated by the converted RibbonLineweightChanged handler. Uses
acadrust::types::LineWeight::from_value(50) (the real constructor;
Lineweight::from_mm does not exist).
- cli_chprop_undo_restores_previous_state: regression test for the CLI
CHPROP command. Before Mission #15 it recorded the undo snapshot after
mutating the entities, so undo restored the post-edit state (a no-op
undo); converting the site to apply_property_op moved the snapshot
before the mutation. #[ignore]d: CLI CHPROP dispatch via
run_command_line / automation-op "run" does not reach the handler in
this test setup. The helper-level invariant is already covered by
apply_property_op_tests::applies_to_each_handle_sets_dirty_and_mutates
and the strengthened missing_entity_does_not_abort_loop.
The fifth proposed test (matchprop_empty_dest_no_dirty) was not added:
MATCHPROP is the interactive command driver (source pick -> dest pick)
and cannot be exercised from a unit test in isolation. The empty-handles
early-return is already covered at the helper level by
empty_handles_does_not_invoke_or_dirty.
Setup lessons that shaped these tests (panel vs scene selection,
LineWeight::from_value, the layer-locking pattern, undo not clearing
dirty) are documented in MISSION_15_REVIEW.md section 6.2.
Full suite: 478 passed / 1 pre-existing fail (diameter_dim_bakes_through_center,
unrelated) / 5 ignored. No regression. No production code changed -- the
new module is #[cfg(test)]-only.

Extract the push-undo → per-handle → invalidate → dirty → refresh
contract into one helper on OpenCADStudio. The helper is the single
source of truth for property-op side effects, so future property
handlers can't forget the cache invalidation or the panel refresh.
Note: MATCHPROP now no-ops when the destination selection is empty
(previously it marked the tab dirty and refreshed the panel). This is
a minor correctness improvement; restore the old behaviour with a
2-line guard at the MATCHPROP call site if desired.

Introduce a cache for the grid overlay to prevent redundant geometry
reconstruction on every UI redraw. Extract the pure projection logic
from draw_grid into a renderer-free grid_segments function, and add
GridKey and GridCanvasState to memoize the resulting Geometry.
The cache key includes all per-pane GridParams and the overlay bounds,
preventing stale geometry when camera changes within the same canvas
size. On a params-key miss, the iced cache is cleared before redrawing
to bypass its bounds-only reuse.
Tests: 8 new unit tests cover key invalidation and state handling.
Benchmarks: uncached geometry ~32 us/frame vs cached decision ~90 ns,
a >99% reduction. Verified: 472 passed / 1 pre-existing failure / 4
ignored.

Sync current main and companion codec changes before preserving unsupported frame rows, rendering in the entity plane, and sharing final layout metrics with placement preview.
INSERT enumerated all block names in a single prompt string, causing unbounded overlay growth and full-screen occlusion in drawings with many blocks. Replace prompt enumeration with a ranked, incrementally filtered suggestion model: BlockPicker maintains precomputed lower/upper caches and usage ranks (MRU/frequency), filters via O(n) substring scan and partial sorting (select_nth_unstable) to O(k), bounded to CLIPROMPTLINES.
Introduce CLIPROMPTLINES (Integer 0-50, Registry, default 3) for the number of temporary prompt lines above the command window; persist in UserSettings, expose via SETVAR and direct entry, enforce in CommandLine::view. Suggestion count is in direct relation to CLIPROMPTLINES (limit = clip, capped to 50).
Make search live without requiring Enter: add CadCommand::on_live_input, implement for INSERT/MINSERT via picker.set_needle, and wire to command-line input paths (Message::CommandInput, on_command_append_char, on_command_backspace). Updates use upper/lower caches and partial sort for <0.2ms per keystroke on 10k blocks, with debounced block-usage persistence (MRU cap 20, freq cap 200) to avoid I/O thrash. Correct tri_count test helper to use display_from_solid.
