`hit` was one number covering five things: resolving candidate handles, the
wire box test, two hatch tests and two mesh tests. `select-commit` now
reports them apart, which immediately reframed the problem — at 186 468
entities the wire box test is 55 ms of 206, the hatch tests are 103, and
handle resolution is 47.
Two changes alongside it, both in the crossing scan.
Skipping a wire already in the selection was keyed by hashing its name, once
per triangle and once per glyph inside the box. A bitmap over wire indices
answers the same question with an array index. The name set stays behind it,
because several wires can share one entity's name and the output dedups by
name; a wire whose name is already in that set now gets tested once more
before being dropped, which costs one projection and changes no output.
The degenerate-wire loop that ends both the box and the lasso scans tested
`seen.contains(wire.name)` before the structural tests beside it. `||`
short-circuits, so with the name lookup last a wire with two or more points —
very nearly all of them — is dropped without hashing anything. That loop
walks every candidate, so it was one string hash per wire in the box.
Rebuilding the properties panel for a 186 468-entity selection took ~112 ms,
and four things in it scaled with the selection for no reason.
The panel filtered the selection down to the active group with
`group.handles.contains(handle)`, a linear scan of a `Vec`, once per selected
entity. The default group is "All", which holds every selected handle, so
both factors are the whole selection: 186 468 squared. Hashing the group once
makes it linear. The measured cost never showed this — 55 ms at 1 993
entities against 112 ms at 186 468 is not a quadratic curve — but the scan is
still wrong, and it is the shape of thing that turns a large selection into
an unresponsive window.
`entity_in_working_plane` clones the entity before it checks whether the
plane is the identity, so with no UCS in play the panel deep-cloned every
selected entity to get back what it was handed. It now borrows, and clones
only where a transform is applied.
`aggregate_sections` built every entity's property list, collected them all,
then folded them together and read each exactly once. A property list is
sections of labels and formatted values, every one an allocation, so a
whole-drawing selection held 186 468 of them in memory at the same time. It
now builds one, folds it, and drops it, and stops once nothing is left in
common. The fold order is unchanged, so the result is too.
The ribbon sync cloned each entity's linetype into a `String` only to compare
it, and kept walking after every field had been found mixed. Once all four
are mixed nothing further can change, so it stops there.
`aggregate_sections` and `merge_sections` had no tests, so the fold that
drives the whole multi-selection panel was resting on the compiler. Two now
cover it: a field the entities agree on keeps its value, one they differ on
reads as varying, and a single entity folds to its own rows.
`properties-detail` and `properties-panel` report the phases, which is how
the panel arm was ruled out as the remaining cost — it does not reach its
5 ms floor at 186 468 entities.
A window over a whole drawing spent 407 ms gathering candidates and 259 ms
testing them, of 825 ms total, at 186 468 entities.
**Gathering** ran eight spatial queries because that is what hover and
snapping need between them. An area selection reads five: the wires and their
segments, plus the fill triangles, pick triangles and glyphs that
`indexed_box_crossing_hits` uses to catch hatches and text inside the box.
The three that exist only for snapping are skipped.
That was worth 148 ms. The rest came from the queries themselves.
`SpatialGrid::query` sorts its result twice — once over the entry indices, to
remove the repeats an entry collects for spanning several cells, and once
over the values. Over a box covering the drawing that is two O(n log n)
passes across 4.4 M elements to remove a handful of duplicates.
`query_unordered` returns the same set in cell order with the duplicates left
in, and reserves the space it needs instead of growing a 17 MB vector in
steps. Gathering went from 515 ms to 69 ms on a synthetic set at that size,
and from 407 ms to 27-40 ms in the application.
Everything an area selection does with the result already dedups and does not
read the order. Click picking keeps the sorted `query`, where scan order
decides which of two overlapping entities a click lands on.
**Testing** projected both endpoints of every segment in the box, then threw
the result away for any wire already selected. A circle or a polyline
contributes one segment per tessellated span, so at 24 spans per wire that is
23 projection pairs out of 24 doing nothing. Skipping a wire once it is in
took a 4.4 M-segment scan from roughly a second to 42 ms.
The overlay path — active after any edit, so most of a working session —
needed the same treatment, including its own merge: `extend_indexed` sorts
and dedups every category, which would have put back the sorts this removes.
`extend_indexed_area` keeps the dedup on `wire_indices`, and must: the window
branch of `box_hit` walks it directly, so a wire left in twice would be
selected twice.
Tests cover the equivalence in both directions: the area query matches the
full one as a set in every category an area selection reads, and the merge
dedups `wire_indices` and nothing else.
Selecting a whole drawing was unusable on a 186 468-entity file. Four costs
scaled with the selection where they did not have to.
Every selected handle triggered a walk of the entire document to find LEADERs
pointing at it. On the file this came from, selecting 471 583 entities in a
585 786-entity drawing did not finish inside eight minutes. A reverse index
built once per geometry epoch answers the same question; a test asserts it
returns exactly what the walk returned, including the case of two leaders on
one annotation.
Group expansion asked the selection about every group: for each selected
handle it scanned each group's own member list. Asking each group once
whether it holds anything selected turns that around.
Selecting and deselecting went one entity at a time, and `deselect_entity`
rebuilt the ordered list with a `retain` per handle, so removing N of M
walked the order list N times. Both now take a slice.
Grips were built for every selected entity. AutoCAD stops at GRIPOBJLIMIT,
and the DWG header does not carry the variable, so its default of 100 stands
in for it.
The remaining two commits are measurement: `select-commit` reports the phases
of a selection separately, which is what showed the bulk paths had been added
to the press-drag branch while a click-move-click window goes through a
different one entirely.

- Modify CUTCLIP command to write cut entities as JSON to system clipboard
- Modify COPYBASE_AT command to write copied entities as JSON to system clipboard
- Entities are serialized as JSON with base point coordinates for cross-platform support
- Clipboard data format: OCS_CLIPBOARD_JSON header + base point + entity data
- Works in web (WASM) build via Clipboard API and native builds via iced clipboard
This fixes the issue where copy command didn't persist to system clipboard in web browser,
allowing proper paste operations and clipboard sharing between application instances.

The first measurement showed four consecutive edits at ~192 ms each with
a handler cost of 0.55 ms. That is below the `update` line's 5 ms
threshold, so the log reports the latency but not what asked for it —
and whether a live command preview is bumping the geometry epoch on every
mouse move is exactly the question the numbers raise.
`nav-prepare` now carries the message label alongside the op.

Drawing a point in a large drawing feels slow, and nothing currently
measures the thing the user actually waits for. `update` times the message
handler, `wires-build` and friends time the rebuild, but the span between
them — press to the frame that shows the new geometry — has no number.
Navigation already has exactly that plumbing: `record_nav_perf` stamps an
instant when the input arrives, `prepare` and `encode` pick it up, and
`nav-prepare` / `nav-render` report `input`, `build`, `prepare` and
`elapsed` from the original event.
`NavPerfOp::Edit` reuses it. `update` snapshots `geometry_epoch` before
dispatch and stamps the sample when it moved, so any message that changed
geometry — a drawn point, a grip commit, an undo — reports its full
latency rather than only the handler's share.
Diagnostic only: `record_nav_perf` sets a pending sample and nothing else,
so no LOD or settle behaviour changes.
Nothing is optimised here on purpose. Four call sites feed the snapper
along different branches, and picking one to instrument before knowing
which dominates is how the earlier rounds of this work were wasted.

Add the typed document facade and plugin IPC adapter. Prepare bulk edits
before mutation, preserve undo and dirty state, keep profile elevations,
validate numeric inputs and session bindings, and generate Python constructors
with typed results.
Reuse existing entity transforms and profile conversion. Compute mass
properties and closed-surface bounds in cadkernel; pin its main revision
6a5e6fc2822f6af6b2611cd605b44437b35158f0. Keep plugin API metadata at version 6.
Validation: 646 native application tests, 597 kernel tests, 12 document API
tests, 91 plugin API tests, 3 Python tests, default/IPC feature builds and
wasm32 check passed.
Delete the thin re-export file; src/app/doc_api.rs now uses ocs_doc_api::convert
directly (use ocs_doc_api::convert + convert::* call sites). Remove the
mod doc_api_convert registration from src/app/mod.rs.
The conversion logic already lives in the crate (src/convert.rs) from the prior
move; the shim was redundant. 623 host lib + 38 doc_api tests green.
Move the 503-line host-independent entity-conversion module (acadrust EntityType
<-> DTO conversions, transform_entity_geometry, entity_to_profile_curves,
bulge_arc_segment, entity_bounds, entity_kind_name, points_aabb) from
src/app/doc_api_convert.rs into crates/ocs_doc_api/src/convert.rs (host feature).
The host file is now a thin re-export (pub use ocs_doc_api::convert::*) so all
existing crate::app::doc_api_convert::* paths keep working unchanged. Zero
coupling risk (the module only touches acadrust + crate DTOs).
623 host lib + 8 crate + 3 consistency green.
