Add the current-state selector, Visibility States dialog and mode/show/hide
controls to the contextual ribbon, using shared icons, tooltips, modal UI
and adaptive flyouts. Disable the controls until a Visibility parameter exists.
Stage state creation, rename, deletion, current-state changes and reordering
until OK. Support copied, show-all and hide-all new states in one undo step,
preserve native graph metadata, and restore current-state identity on undo/redo.
Implement nonsaved BVMODE and display-only reveal during BVSHOW selection.
Cancelling selection leaves saved visibility flags and history unchanged.
Keep the existing command-line state workflows available.
Validation: 6 targeted tests; 277 block, 31 app dock, 35 ribbon and 12 history
checks passed (overlapping filters). All 17 local DWG fixtures passed in-memory
DWG/DXF preservation checks with unchanged original checksums.
The guard remembered only the last announced (tab, generation), so
switching A -> B -> A announced A's load again. Each tab now carries
its own pending flag, set when a document is installed and cleared by
the boundary dispatch.

Reference-only entities (plugin API v9): a scene-scoped, in-memory
designation for plugin-owned display geometry, plus HostNotification
dispatch to native plugins so they can re-mark on DocumentOpened.
Resolves the new DeltaSnapshot site in block_editor.rs.

Close the no-load-callback gap: on_notification was a dead dispatch sink —
a plugin had no way to learn that the active document changed, the selection
changed, or that a document opened, so runtime designations could not be
re-seeded after a load.
Dispatch the existing plain variants at the fingerprint-guarded boundaries
the v4 bridge already uses: DocumentChanged (the active tab's settled
geometry epoch) and SelectionChanged (the selection set) leave through
BuiltinPlugin::on_notification at the post-message boundary — after the
mutation settles and pending history scopes closed, never mid-undo or
mid-pick — and at the automation post-op boundary. Plugin-initiated writes
publish immediately after settling, like the drawing-changed event; the
boundary fingerprint guard deduplicates.
Add the additive HostNotification::DocumentOpened { tab_id } variant
(discriminant 10, the counterpart of DocumentTabClosed): fired exactly once
per whole-document install — file open, template new, system open — keyed on
a new per-tab document generation, so an edit can never repeat it and a
reload fires it once. The API version stays v9 (the bump is unreleased).
Write semantics for handlers, tested and documented: a handler may call
HostApi write methods through the same session (set_reference_only at
minimum); its write bumps the epoch, the next boundary notifies once more,
and because re-marking already-designated geometry is a documented no-op —
no epoch bump, no undo step, no publish — the loop terminates. History
(undo/redo) replay itself emits nothing; the boundary is the only channel.
No Python mapping, like the rest of this increment.
Per the upstream review of the XDATA-based storage: the host no longer writes
its own state into the saved file. The marker record under the host-owned OCS
APPID, the on-first-use APPID registration and the verbatim-EED rewrite
handling are removed; the single source of truth is a scene-scoped in-memory
set of entity handles (Scene::reference_only) that dies with the drawing tab,
so a reopened file starts undesignated and the owning plugin re-marks on the
document-opened notification.
All behaviour sites are unchanged, driven by the set: the wire stamp moves
from an XDATA read to a set lookup threaded through the tessellation
pipelines (tessellate_entity and the dimension text path take the handle set
as a plain parameter), and the pick filters, selection retains and
update/erase refusals read Scene::is_reference_only.
Undo keeps the entity-write contract: set mutations are recorded as explicit
first-touch before/after values on each history delta (the parametric-
constraints channel pattern). A designation inside a plugin push_undo scope
joins it, a scope-less change is one step of its own, an idempotent re-mark
records nothing, erasing a designated entity drops the set entry with the
entity, and undo/redo restores entity and designation together.
The round-trip test is inverted: reference_only_designation_is_not_written_
to_dwg_or_dxf now asserts the marker appears in neither format's bytes, that
no OCS APPID or marker record survives a reload, and that the designation
stays live in memory.
Preview the current unsaved block in a disposable drawing with independent history. Keep normal Draw tools available, append Close Test Block, and return to the original editor without saving. Guard persistence paths and handle refresh and parent-close lifecycle by stable document identity.
Document tab: every concrete colour the drawing uses (objects, block
definitions and layers), found in one pass when the panel opens, as a
grid of swatches sortable by recently used, most used, colour and colour
number. The recently-used list is now kept per drawing, so the ribbon's
Recent row shows this drawing's colours.
Color books tab: load AutoCAD .acb colour books (remembered in the
settings on desktop), browse them page by page with the page strip,
search by name and see the RGB equivalent. A book colour is applied as
RGB plus its BOOK$NAME identity on objects and layers instead of
dropping the name.

props_asym_scale was app-global keyed by raw handle values, but fresh documents restart numbering at seed 1, leaking one tab's unchecked Uniform box into another tab reusing the value. The set moves to DocumentTab; all uses tab-scoped. Also removes a dead destructure left in overlay.rs. Test: asym_scale_opt_out_does_not_leak_across_tabs with handle-reuse premise assert (RED first). Full suite: 2025 passed / 0 failed / 25 ignored, zero warnings.

The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

The reference follows the cursor while its insertion point, scale or
rotation is asked (preview-only PScale/PX/PY/PZ/PRotate included); a
relative path chosen before the drawing had a file becomes relative on the
first save, and relative paths start from "./" at or below the drawing's
folder; -XREF name options report "No matching xref names found.".

One writer (plot_settings_from_dialog) now serves both the layout's embedded
settings and named page setups, so the two can no longer drift apart:
- media are stored as the portrait sheet with the orientation in the
rotation code (0/90/180/270; upside-down adds a half turn) instead of
swapped width/height with rotation limited to 0/180
- standard scales are written by their code (1:1 … 100:1) with matching
numerator/denominator; other scales as a readable custom ratio in the
layout's own paper unit, converting from the drawing's scale-family unit
(a metre drawing plotting "1:100" stores 10 mm = 1 unit, an inch layout
stores 1 in = 2540 units); reading converts back and keeps a ratio the
scale list has no name for instead of snapping to 1:1
- the layout's paper unit and every flag the dialog does not edit survive a
round trip untouched; layout limits follow the paper-space unit
- new drawings, new layouts, CLEAR and the automation "new" op share one
default page setup (canonical A4 name, rotation 90, none_device, 1:1
layout plot) through Scene::reset_to_new_drawing
Scene gains scale_family_unit_mm, scale_ratio and a scale-name ratio parser
(ratios and architectural names). Round-trip tests cover orientation,
standard/custom/fit scales, unit conversion, named-setup parity, preserved
flags and the default layout.

CREATESKETCH opens a sketch on the current UCS, or on one of the three
origin planes with XY, XZ or YZ. FINISHSKETCH closes it again.
Nothing here is new machinery: the plane is a UCS, the square-on view
is PLAN, the drafting aids are the snapper. What the pair adds is
holding them together and putting them back afterwards, including the
snap master state, so a user who works with snapping off gets that
back rather than silently keeping it.
Squaring the view up is not cosmetic. Drawing on a plane seen nearly
edge-on is the main way geometry lands somewhere the user did not
mean, because a few pixels of cursor travel cover a long way in world
space.
A sketch is a mode rather than a document object, so what it produces
is ordinary model-space geometry and the file stays a DWG other
software can open. Whatever was drawn becomes the Previous selection
set, so EXTRUDE then Previous consumes it without making the user
reselect a profile they just finished.
The command menu now follows the commercial solutions' layout row for row: Enter, Cancel,
Recent Input ▸, the command's keywords, Snap Overrides ▸ (every object snap
with its glyph, Mid Between 2 Points, None, Osnap Settings…), then Pan and
Zoom. Pan / Zoom run transparently while a command is active ('PAN,
'ZOOM …): navigation modes leave the command untouched and an interactive
ZOOM Window parks it and resumes it afterwards. Rows carry an icon gutter
so labels align; the Enter row shows a default value ("<0.5000>") as its
hint instead of a second finish row.
ARC gets the commercial solutions' prompt flow with all keywords: start [Center], second
point [Center/End], end; after Center: end [Angle/chord Length]; after
End: center [Angle/Direction/Radius]; Enter continues tangent. The
previous default (Center/Start/End with method codes) stays as ARC_CSE.
Object snaps gain a one-shot "None" override. New strings in all locales.

The viewport context menu is now built from a pure model
(ui::popup::context_menu) rendered by the overlay: while a command runs it
offers Enter / Cancel / every keyword of the command's options() with the
keyword shown as a hint, a Recent Input submenu and M2P; when idle it offers
Repeat, Recent Input, Clipboard, Undo/Redo with history labels, the edit
block (Erase/Move/Copy/Scale/Rotate/Mirror/Draw Order), Isolate, Pan/Zoom,
selection tools, Properties and Options. The default row is anchored under
the pointer and the menu is keyboard-navigable (arrows, Enter, mnemonic
letters; any other key closes it and types into the command line).
Right-click behaviour is a user preference (Options → User Preferences,
SHORTCUTMENU / SHORTCUTMENUDURATION): shortcut menu (commercial solutions default),
time-sensitive, or the previous Enter-first cycle.
LINE gains options() (Close/Undo/eXit).

Ports the fixes from fix/osnap-circle-arc-ellipse-intersection (and
this session's audit follow-up) onto this branch. All are independent
correctness/reliability fixes, unrelated to the parametric-constraint-
system work also in progress here.
1. OSNAP Intersection snap used a tessellated approximation instead of
exact geometry (GitHub discussion #1052): a circle/arc always
tessellates at a fixed 48 segments in the resident wire set
regardless of radius or zoom, so every circle/arc intersection snap
was off by construction. Added exact_circle_intersections, a
closed-form, frame-independent circle/arc-vs-circle/arc solver,
wired into both Intersection-snap code paths ahead of the
tessellated sweep. This branch's TangentGeom predates the
PlanarEllipse variant added upstream, so the ellipse/line
generalization from the upstream fix isn't ported here — this
covers the literal reported bug (a circle-circle case) using only
variants this branch already has.
2. Unbounded MINSERT allocation: array_offsets() reserved one Vec
element per array instance with row/column counts parsed as
unchecked u16s — a corrupt 65535x65535 pair requests ~96 GiB.
Fixed with a documented instance budget (20,000), enforced at both
the load-time corrupt-entity filter and a render-graph failsafe.
3. MINSERT spacing was scaled by the block's own scale:
insert_instance_transform composed the offset translation before
the instance transform, so x/y block scale multiplied the row/
column spacing too. Fixed by orienting the offset with rotation +
OCS only, then translating the already-scaled instance transform.
4. Automation "open" skipped the finalization (block-origin
normalization, raster-path resolution, source_path) and corrupt-
entity purge a UI open always runs. Added
io::load_bytes_finalized(path, bytes), used by automation's "open"
handler, which now also reports the purge count.
5. Material maps were uploaded without checking
device.limits().max_texture_dimension_2d, unlike raster-image
rendering (which already tiles to that limit). A mesh material is
sampled by UV, so it can't use the same tiling trick — instead,
upload_rgba_texture now downscales an oversized image before
upload, falling back to the 1x1 material color if malformed.
6. Sketch-constraint persistence/undo, audit-found while reviewing
this branch's own constraint system:
- Clearing every constraint in a scope after a prior non-empty save
left the stale XRecord in place, resurrecting the deleted
constraints on the next load. materialize_sketch_constraints_for_
save now actively removes the XRecord when a scope goes back to
empty.
- ERASE removing an entity took its constraints with it (design
doc's deletion policy), but sketch_constraints lives on Scene,
outside document/document.objects, so nothing captured that
mutation for undo — the erased geometry came back on undo, but
its constraints didn't. refresh_sketch_constraints's deletion
pass now records the touched scope's before-image into the same
UndoRecording the entity removal rides in, threaded through a new
sketch_constraints channel on DeltaSnapshot, so one undo restores
both together. HistorySnapshot::Delta is now boxed (clippy
flagged the resulting size skew across undo/redo stack variants).
31 new/adapted tests across all six fixes. Full workspace suite passes
except the one pre-existing, unrelated font-test failure also present
on main.

Ports FreeCAD's planegcs 2D geometric constraint solver to Rust as a new
crates/ocs_gcs workspace member, and wires it into the document/scene model
as a persistent SketchConstraintSet: Coincident, Horizontal/Vertical,
Parallel/Perpendicular, Equal, Tangent, Distance, Angle and Radius
constraints that re-solve live (including mid-drag, not just on release),
render glyphs and a DOF badge, flag conflicts with a one-click resolver
pill, and round-trip through save/load via an XRecord blob.
Also includes docs/command_reference.md (a statically generated reference
of every registered command and its prompt sequence) and
docs/named_parameters_design.md + docs/backlog.md, which hand off the next
queued feature (a named-parameter/expression table) and consolidate every
deliberate scope-down and open gap found along the way, so a fresh session
has a complete starting point.
