Felix RiestraandClaude Sonnet 5 eca4e9d7a5 Document Properties-panel constraints/parameters, pill toggle, icon
redesign, and the ellipse solver fix in CHANGELOG

Felix RiestraandClaude Sonnet 5 bd9a2d08f7 Add Properties-panel Constraints/Parameters sections, a constraint-pill
value toggle, and redesigned constraint-ribbon icons

Properties panel:
- New "Parameters" section (shown with no selection) listing every named
  parameter with inline name/formula editing, add, and delete, backed by
  new PropValue::ParamRow/ParamAddRow and command_driver handlers
  (resolve_named_parameter_edit, on_prop_param_commit/_delete/_add_new).
  A fresh parameter's formula now defaults to "1", not "0" — a 0-length
  seed value is a genuine solver singularity for a Distance constraint
  driven by that parameter, with no defined direction to grow back out of.
- New "Constraints" section (shown for a single selected entity) listing
  every constraint touching it as a clickable PropValue::EntityLink that
  selects the linked entities in the viewport, danger-tinted when the
  constraint conflicts.

Constraint pills:
- New Options > General toggle, "Show values and parameter names on
  constraint markers" (on by default, persisted). Off, every pill shows
  just its bare glyph instead of glyph+driven-value/parameter-name — the
  glyph alone is enough to see a constraint is present, without the value
  text covering nearby geometry on a dense sketch.

Constraint-ribbon icons:
- Replaced all 18 unicode/letter glyph icons (including the plain "F",
  "L", "M", "S" letters) with proper SVGs under assets/icons/constrain/,
  matching the Modify section's two-color style (#B4B6B9 white / #6DB7ED
  blue, consistent stroke width). Tangent reuses the Draw section's
  white-arc-plus-blue-dots motif.

Felix RiestraandClaude Sonnet 5 faf3473b2b Fix ellipse solver drift: pin focus1 offset from center, not focus1 itself
An ocs_gcs Ellipse stores focus1 as an absolute point rather than an
offset from center, so a constraint that pulls only on center (e.g.
Concentric) left focus1's absolute coordinates untouched while center
moved — changing the derived focus1-center vector that major_axis and
minor_axis_ratio are computed from on write-back, so the ellipse visibly
rotated and reshaped even though nothing asked it to.

solve_scope now adds two Difference constraints per registered ellipse
pinning focus1.x-center.x and focus1.y-center.y to their pre-solve
values, so focus1 translates rigidly with center unless something
actually constrains it. Fixed's Ellipse arm no longer re-pins focus1
directly since that's now redundant with these rules.

Felix RiestraandClaude Sonnet 5 d27eb625ca fix(constraints): split large XRecord Chunk data across entries for DWG
The DWG writer truncates an XRecord Chunk to u8::MAX bytes, so a sketch's
constraint set or named-parameter table silently lost every entry on the
next DWG open once serialization passed ~255 bytes (found live: a
23-constraint demo round-tripped fine through DXF but came back empty
through DWG). Split the blob across multiple same-code 310 entries on
save and reassemble them on load, entirely on the OCS side.

Felix RiestraandClaude Sonnet 5 9f7972ee0d Register all sketch-constraint commands in the autocomplete registry
None of the 17 constraint commands (HCONSTRAINT, VCONSTRAINT,
PCONSTRAINT, QCONSTRAINT, ECONSTRAINT, TCONSTRAINT, NCONSTRAINT,
NRCONSTRAINT, LCONSTRAINT, FXCONSTRAINT, SYCONSTRAINT, CCONSTRAINT,
EDCONSTRAINT, CPCONSTRAINT, MPCONSTRAINT, OCCONSTRAINT, DCONSTRAINT,
ACONSTRAINT) carried an inventory::submit! registration, so they were
invisible to command-line autocomplete, the MCP commands listing, and
the ALIASEDIT shortcut editor (which rejects a custom shortcut target
that isn't in this same registry). Each constraint module now
registers itself, with a regression test pinning the full set.

Felix RiestraandClaude Sonnet 5 3d0a41b69a Extend sketch constraints toward FreeCAD parity, staying DWG-native-compatible
Arcs are now full constraint participants (center/radius via the existing
Circle-shaped solver path, plus real endpoints kept consistent by arc-rules
CurveValue constraints); adds Diameter/DistanceX/DistanceY/ArcLength/Normal
constraint kinds and initial Ellipse entity support (center-based
constraints only). DWG-native class mappings and gaps (ArcLength, Ellipse)
are grounded against real ObjectARX headers rather than guessed, so files
saved with DWG-native constraints stay honest about what AutoCAD can
actually represent.

Also fixes a case-sensitivity bug where a lowercase named-parameter
reference typed at a dimensional constraint's value prompt was rejected
(the command line uppercases SingleToken input before the parameter-name
lookup), and adds a "Used by" column to the Named Parameters panel.

Felix RiestraandClaude Sonnet 5 eb96e8b6ed Fix silent TTF-fallback failures for variable system fonts (Turkish 'Ğ')
Root cause (found by instrumenting build_fallback and reading
ttf-parser's own source, not guessed): cosmic-text's fallback search
picks macOS's system font (San Francisco / SFNS.ttf) for any codepoint
no stroke font or explicitly-requested family covers. It's a variable
TrueType font, and ttf-parser's outline_glyph() resolves a variable
glyph's contours through its gvar table's deltas relative to whatever
variation coordinates are currently set on the Face — an unset Face
has none, so outline_glyph silently returns None (not an error) for
such a glyph. The caller then still returned Some(Glyph { strokes:
vec![], .. }): a "resolved" glyph with nothing to render, no error
anywhere.

Two-part fix:
1. pin_default_variations() sets every variation axis to its own
   default value before outlining, applied at all TTF outline-
   extraction sites (both build_fallback variants, both build_shaped
   variants, and the plain by-family glyph() lookup). This alone
   wasn't sufficient for San Francisco specifically — even pinned, its
   outline still didn't resolve for the glyphs this bug was found on,
   apparently because ttf-parser can't retrieve base glyf data gvar
   needs for at least some of that font's accented Latin glyphs.
2. So build_fallback() now treats "resolved a glyph ID but couldn't
   extract its outline" as a real failure (outline_from_face returns
   None, not an empty glyph) and falls through to a direct fontdb scan
   for any other installed font that also covers the character and
   can actually be outlined, rather than silently giving up.

Full workspace test suite: 813 passed, 0 failed (previously 812
passed, 1 failed — this was the one pre-existing failure carried
through the entire session).

Felix RiestraandClaude Sonnet 5 d675244fb8 Merge branch 'main' into feature/parametric-constraint-system
Brings in 54 commits from origin/main: a selection-performance overhaul,
surface thickening, GPU-native wide/tapered stroke rendering, continued
ocs_doc_api evolution, and assorted fixes/polish (block double-click
editing, DWG hatch/database repair, clipboard, collapsible Properties
sections).

Six real conflicts, all where this branch had independently re-applied
a fix upstream later revised or already carried natively:

- src/app/automation.rs, src/app/command_driver.rs: combined both
  sides — kept this branch's sketch-constraint/named-parameter loading
  on "new"/"open", adopted main's Scene::clear()/material_base_dir and
  its newer rebuild_derived_caches() over the older bump_geometry().
  Scene::clear() (src/scene/entity.rs) now also resets
  sketch_constraints/named_parameters, so every caller gets this for
  free instead of each call site repeating it.
- src/io/mod.rs, src/scene/render_graph.rs: adopted main's design
  outright (commit 973af87d, authored by Hakan directly) — a large
  MINSERT is no longer purged as "corrupt" at load, only its rendering
  is bounded, preserving the source data. This branch's own earlier
  design (reject at load) predates that revision.
- src/scene/pipeline/mesh_gpu.rs: adopted main's valid_rgba_size()
  guard (a real robustness improvement over this branch's version).
- src/snap.rs: replaced wholesale with main's version — this branch's
  copy was an explicit verbatim snapshot from an earlier upstream PR
  (commit 4c264b8c) with zero constraint-system-specific content, and
  main has since evolved it considerably further.

Also removed two now-dead duplicates the merge surfaced without a
conflict marker (both branches had independently fixed the same
things): the OPTIONS/OP command dispatch/autocomplete entries, and
automation.rs's open_finalizes_and_purges_like_the_ui_open_path test
(kept main's version, which covers strictly more: solid_models/
material_base_dir reset on "new").

Full workspace suite passes (812 lib tests + this branch's own 24
constraint/persistence integration tests) except the one pre-existing,
unrelated font-test failure already present on main. Zero clippy
findings in the hand-written merge resolution itself; the ~1,171
warnings clippy reports are pre-existing in the 54 absorbed commits,
not introduced here.

Felix RiestraandClaude Sonnet 5 31b5ef4ec3 Add 8 geometric constraint kinds and an opt-in DWG-native persistence toggle
New ConstraintKind variants — Concentric, CenterPoint, Colinear, Midpoint,
Fixed, PointOnCurve, EqualDistance, Symmetric — each built entirely from
existing ocs_gcs (FreeCAD planegcs) primitives, no new solver math needed.
build_constraint now returns Vec<Rc<dyn Constraint>> instead of
Option<Rc<...>>, generalizing the old Coincident-only "needs a second
system-level constraint" special case to every kind that needs one.
Wired into the ribbon (7 new buttons), a new point+pre-selected-entity
command for CenterPoint/Midpoint/PointOnCurve, a new 4-point command for
EqualDistance, and the existing DWG-native class-name mapping (all 8 reuse
the same generic "plain Geometrical node" path already built for
Coincident/Horizontal/etc.). Deliberately not modeled: Normal and
EqualCurvature, which for this app's Line/Circle-only entity model would
just be Perpendicular and Equal wearing different DWG class names.

Also makes DWG-native constraint persistence opt-in (Options > General,
off by default) rather than unconditional: a scope that doesn't yet have
the native graph is only given one when the setting is on, but a scope
that already has one — from an earlier save, or a file that came from
real AutoCAD — keeps getting it resynced regardless of the setting, so
toggling it off never freezes a stale graph in place.

Felix RiestraandClaude Sonnet 5 cf33a1d019 Add DWG/DXF-native constraint persistence alongside the XRecord format
Implements docs/dwg_constraint_compatibility_design.md's staged plan in
full: materializes the sketch-constraint set as acadrust's real
AssocNetwork/Assoc2dConstraintGroup object graph on save, additive to
the existing OCS_SKETCH_CONSTRAINTS XRecord, so files also carry
constraints AutoCAD/BricsCAD recognize as their own native objects
(per Hakan's request on the upstream project). Covers every
ConstraintKind, including AssocVariable wiring for named-parameter
driving values, and clears+rebuilds on each save.

DWG round-trips the full dependency chain; DXF only keeps the
constraint-group shell since acadrust's own DXF writer deliberately
omits AssocDependency-family objects. Both behaviors are covered by
tests and documented in the design doc's progress section, along with
two other implementation-time findings (skipping the NOD-anchored
top-level network, and the DWG writer's root-node/connections wire
format).

Felix RiestraandClaude Sonnet 5 5d93476c01 Add DWG-native constraint compatibility design doc
Hakan (upstream maintainer) asked for the sketch-constraint system to
persist using the constraint object model already exposed in acadrust/
cadcodec (Assoc2dConstraintGroup, AssocConstraintNode), so a file saved
by OpenCADStudio carries constraints AutoCAD/BricsCAD recognize as
their own native objects, not just an opaque custom XRecord blob.

Covers:
- The full ConstraintKind -> AssocConstraintNodeData mapping table,
  grounded in build_constraint's actual refs shapes (the real contract,
  not the doc comments).
- The geometry-node mapping for SketchRef (line/circle/arc/point
  references) onto Line/BoundedLine/Circle/Arc/ImplicitPoint nodes.
- The AssocNetwork -> AssocAction -> Assoc2dConstraintGroup graph shape
  actually needed, not just a flat data swap.
- A proposed additive persistence strategy: write both our own
  OCS_SKETCH_CONSTRAINTS XRecord and the native graph, since our model
  carries things (DrivingValue::Named) the native graph can't yet
  losslessly express.
- Known gaps: Equal has no length/radius sub-kind split natively,
  several AutoCAD constraint types we don't model at all, Tangent
  involving an Arc (a pre-existing gap in the constraint system,
  unrelated to DWG compatibility).

Three of five open questions are resolved against Autodesk's own
primary sources rather than left as inference: the ObjectARX 2012 SDK's
own C++ headers (mirrored on GitHub, Autodesk's own copyright notice
grants free use/distribution -- it's the SDK Autodesk publishes for
third-party interop) and Autodesk's live public ObjectARX reference
site. Confirmed: the associative network's dictionary key
("ACAD_ASSOCNETWORK"), the AcDb::ImplicitPointType enum settling how
SketchRef's point markers map to constraint geometry nodes, and that
AssocVariable's evaluator field can be left empty (Autodesk's own doc:
"the default evaluator for current acad version will be used"). Two
questions remain and need a real write-then-open test rather than more
reading: whether AutoCAD tolerates a partially-populated graph, and
DWG version gating on fields not yet checked.

Suggested staged approach: prove out Horizontal/Vertical on a single
Line first (sidesteps the value-dependency wiring), verify it opens
cleanly in real AutoCAD/BricsCAD or a DWG inspector, before writing
more of the graph on an unverified foundation. Design only -- no
implementation yet.

Felix RiestraandClaude Sonnet 5 7cddf31bcb Add named parameters, UI scale setting, OPTIONS/OP dispatch, and help manual
Named parameters (docs/named_parameters_design.md, stages 3-4):
- ParameterTable (src/scene/named_parameters.rs): a document-wide table of
  named formulas, each resolved through a shared expression evaluator with
  cross-parameter references, cycle detection, and division-by-zero/parse
  error reporting. SketchConstraint::driving_param becomes DrivingValue
  (Literal | Named) instead of a bare f64, resolved at solve time by
  sketch_solve::build_constraint via Scene::named_parameters.
- Persistence (src/scene/named_parameters_persist.rs): same lazy XRecord
  model sketch_persist.rs already established, synced around open/save.
  Bumps the sketch-constraint XRecord's own format version (1 -> 2) since
  DrivingValue's shape doesn't line up with a version-1 blob's bytes.
- PARAMETERS command and its editor (src/ui/window/named_parameters.rs):
  add/remove/edit rows, live validation, duplicate-name detection: Apply
  defines the table and re-solves every constraint scope with a
  named-parameter-driven constraint (command_driver.rs). Distance/Angle
  constraint prompts (modules/draw/constrain/value.rs) now accept either a
  literal or an existing parameter's name, mirroring how the constraint's
  own value prompt already worked.
- Undo scope-down carried over from this project's own established pattern
  (constraint-system stage 9): the geometry an Apply moves is one undo
  step, but the parameter table edit itself has no undo entry yet — a
  documented follow-up, not a silent gap.

UI scale setting (src/app/settings.rs, app/mod.rs, ui/window/options.rs):
  a whole-interface scale percentage (50-200%), wired directly into iced's
  own per-window scale_factor hook rather than per-panel font-size
  plumbing, so it applies immediately to every panel, dialog, and the
  ribbon at once. Persisted alongside the existing lineweight-display-scale
  setting.

OPTIONS/OP command dispatch (app/commands/view.rs, app/commands/mod.rs):
  OPTIONS was registered for autocomplete but had no dispatch arm — the
  Start-tab welcome screen's own button was the only way to reach it.
  Found live-testing the UI-scale setting, unrelated to that feature
  itself. "OP" is AutoCAD's own short alias.

help/: a new self-contained static user-help manual (manual.md as the
authored source, tools/build_help.py splits it into the committed static
HTML pages plus search index) — not yet wired into the application.

64 new/updated tests across the named-parameters and constraint-prompt
changes.

Felix RiestraandClaude Sonnet 5 4c264b8c69 Port the PlanarEllipse tangent-geom variant and full OSNAP ellipse fix
Completes the OSNAP intersection port from 44deee2a: that commit
explicitly deferred ellipse support because this branch's TangentGeom
predates the PlanarEllipse variant added upstream (this branch was cut
from an older main snapshot, ~99 commits behind on unrelated work).
Ports just the variant and its minimal direct dependents, not the
other unrelated evolution in those 99 commits (a separate analytical
GPU fast-path for circle/arc/ellipse rendering, tessellation changes,
etc. — out of scope here).

- wire_model.rs: copied verbatim from main. Restores the
  PlanarEllipse variant plus TangentGeom's translated/rotated/scaled/
  mirrored methods (this branch was missing all four transform methods
  entirely, not just ellipse support in them — a live-drag preview
  wire's tangent_geoms weren't being updated at all during a
  translate/rotate/scale/mirror preview).
- entities/ellipse.rs: restored building the PlanarEllipse tangent_geom
  for a committed ellipse/elliptical-arc entity's RenderEntity — this
  is what makes ellipses queryable by OSNAP at all (the resident wire
  set is what Intersection/Tangent snap search).
- entities/dimension.rs, scene/cache/block_cache.rs: added back the
  three PlanarEllipse match arms needed for exhaustiveness (OCS-to-WCS
  remapping, prototype-wire translation, and instance-transform
  application) — each a self-contained arm restoring exactly the
  ellipse case, not touching the surrounding logic.
- snap.rs: replaced with the exact fix from the upstream PR (HakanSeven12/OpenCADStudio#1104)
  branch, whose snap.rs was already verified to differ from main by
  nothing but that fix. Upgrades the earlier circle/arc-only port to
  the full exact_curve_intersections path: line-vs-circle/arc/ellipse
  and ellipse-vs-circle/arc/ellipse, via cadkernel::geom2d::intersect
  over a shared embedding plane, including the anti-parallel-normal
  reflection fix for both Arc and PlanarEllipse.

7 additional tests now build and pass (line/ellipse intersection
cases, both anti-parallel-normal regressions) plus the wire-transform
test wire_model.rs already carried. Full workspace suite passes except
the one pre-existing, unrelated font-test failure also present on
main.

Felix RiestraandClaude Sonnet 5 44deee2ac9 Port 6 audit-found bugs from the upstream OSNAP fix branch
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.

Felix RiestraandClaude Sonnet 5 78259c7aed Fix OSNAP Intersection snap using tessellated approximation
github.com/HakanSeven12/OpenCADStudio discussion #1052: constructing a
3-4-5 right triangle by drawing two circles (radius 3 and 4, centers 5
apart) and using OSNAP Intersection to find their crossing points gave
measured side lengths that didn't match the entered radii.

OSNAP's Intersection snap found candidate points by sweeping line
segments from each wire's *tessellated* polyline approximation, never
the entity's real geometry. Circles feeding the resident wire set
always tessellate at a fixed 48 segments (Scene::resident_wires_for
passes wpp=None deliberately, to avoid re-tessellating on every camera
pan/zoom) regardless of radius or zoom — so every circle/arc/ellipse
intersection snap was already off by construction, not just at extreme
zoom levels. Arcs, ellipses, and splines have the same problem via
their own fixed-angle tessellation.

Added an exact intersection path that bypasses tessellation entirely,
used by both call sites in the Intersection-snap code (the indexed/
local fast path and the brute-force wire-pair fallback), falling back
to the original tessellated sweep for anything it can't resolve:

- exact_circle_intersections: closed-form circle/circle intersection
  for any pair of Circle/Arc entities (frame-independent — each side's
  own arc sweep is checked against its own native axis, so two arcs in
  differently rotated coordinate frames still resolve correctly).
- exact_curve_intersections: a more general path for anything
  involving a line or an ellipse — embeds both entities into a shared
  working plane and dispatches to cadkernel::geom2d::intersect (an
  exact/tolerance-converged solver already vendored in this repo's own
  dependency but previously unused for this purpose). Handles a
  reflection hazard the naive version would miss: when an entity's own
  normal is anti-parallel to the shared embedding frame's normal, the
  mapping mirrors the parametrization and reverses which physical arc
  a [start, end] range refers to — both the Arc and PlanarEllipse
  branches detect this and swap start/end to compensate.

The only remaining case still going through the tessellated sweep is a
compound polyline chain with a bulge segment (not a single recognized
curve — it would need its own per-segment bookkeeping this pass
doesn't add).

12 new tests, including the reported 3-4-5 case verified against the
exact expected crossing points, arcs in differently rotated frames,
and the anti-parallel-normal reflection case for both Arc and Ellipse
(independently verified via a Python script for exact precision).

Felix RiestraandClaude Sonnet 5 86e3a0c794 Downscale oversized material maps to the GPU texture limit
Material map images (diffuse/specular/reflection/opacity/bump/
refraction/normal) were decoded at their original file dimensions and
uploaded to wgpu without checking device.limits().max_texture_dimension_2d,
unlike raster-image rendering, which already tiles to that same limit.
An oversized material map produced a wgpu validation error and left
the material unusable; the global error handler prevented a process
abort, but never produced a valid texture either.

A mesh material is sampled by UV across a surface, so it can't use the
same per-quad tiling trick raster images use. Instead,
upload_rgba_texture now checks the decoded image against the device's
texture-size limit and downscales it (aspect-preserving, via
image::imageops::resize) before upload when it's oversized, falling
back to the existing 1x1 material color if the decoded buffer is
malformed (its length doesn't match its reported dimensions).

3 new tests cover the resize math (aspect ratio preserved, both
dimensions respect the limit) and the malformed-input fallback.

Felix RiestraandClaude Sonnet 5 d0025d6ddf Make automation "open" run the same finalization as a UI open
Automation's "open" op called io::load_bytes directly and installed
the result as-is, skipping everything the canonical path-based loader
(load_file_for_open / finalize_loaded_outcome) runs after parsing:
block-origin normalization for legacy non-zero-origin blocks,
relative raster/material path resolution, source_path assignment,
and the corrupt-entity purge the UI open path always applies. The
same file opened two ways behaved differently, and headless/automation
use was more exposed to malformed geometry with no filter at all.

Added io::load_bytes_finalized(path, bytes), which runs load_bytes
plus that same normalization and purge using the real path (not just
its basename, which the old code passed to load_bytes as the "name"
parameter — losing the directory needed for raster-path resolution
and source_path). automation.rs's "open" handler now uses it and
reports the purge count as a "purged" field in the response.

load_bytes itself is unchanged, since the byte round-trip tests
(sketch_persist.rs, named_parameters_persist.rs) deliberately want
the simpler byte-only path with no real filesystem path behind it.

New test constructs a document with one normal and one corrupt
(zero-radius) entity, saves it, opens it through automation, and
checks the corrupt entity was purged and source_path was set —
proving the automation path now matches the UI path.

Felix RiestraandClaude Sonnet 5 8bc9e83c2e Fix unbounded MINSERT allocation and scale-multiplied spacing
Two independent MINSERT (array INSERT) bugs found while auditing
render_graph.rs:

1. array_offsets() reserved and filled one Vec element per array
   instance, with row_count/column_count parsed as unchecked u16s.
   A corrupt or adversarial 65535x65535 pair requests 4,294,836,225
   instances (~96 GiB) before any GPU-side chunking limit can help,
   and before the render graph even reaches the GPU. Fixed with a
   documented instance budget (20,000) enforced at both the load-time
   corrupt-entity filter (is_entity_corrupt, matching the existing
   polyline/spline vertex-count guards) and a failsafe clamp in
   array_offsets itself, for an insert built or edited some other way.

2. insert_instance_transform composed the per-instance row/column
   offset translation *before* the INSERT's own transform, so the
   block's x/y scale multiplied the spacing along with the block
   contents — an INSERT with x-scale 2 and column spacing 10 rendered
   20 units between columns instead of 10. The pinned CAD model's own
   Insert::array_points() confirms the correct behavior: spacing
   rotates with the insert but is never scaled. Fixed by orienting the
   offset with rotation + OCS only, then translating the already-
   composed (scaled) instance transform by that world-space vector.

7 new tests cover both: pathological/reasonable instance counts at
the load-time filter and the render-graph failsafe, and instance
transforms for scaled and rotated arrays.

Felix RiestraandClaude Sonnet 5 63a74b19a9 Add persistent sketch-constraint system (ocs_gcs port) and named-parameters handoff docs
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.

Felix RiestraandClaude Sonnet 5 a39c7b8f71 macOS launcher: re-assert Accessory policy after handling an event
Handling a document-open Apple Event (a warm "Open With" while the app
is already running) silently promotes this process from
NSApplicationActivationPolicyAccessory to a normal foreground app —
confirmed with lsappinfo, not assumed: its own entry flips from
type="UIElement" to type="Foreground" the instant it handles a second
Apple Event (a cold launch's own first event doesn't trigger this).
That gave the launcher its own, contentless Dock icon sitting next to
the real editor's, both apparently "the same app" to the user but
actually two separate Dock entries.

Re-set Accessory explicitly right after relaying, in the one place
every open (cold fallback, document open, and reopen-while-running)
already funnels through.

Felix RiestraandClaude Sonnet 5 24e9a7663d macOS launcher: handle reopen while already running with no window
Quitting the real GUI binary (Cmd+Q) leaves the launcher itself still
running — that's by design, so it can keep relaying opens for the
session. But reopening the app afterward (Dock icon, double-clicking
it in Finder again) reactivates that same long-lived launcher process
rather than triggering a fresh cold launch, since Launch Services
still considers the bundle running. Neither of the delegate methods
already handled covered that: applicationDidFinishLaunching: only
fires once, at the launcher's own original cold start, and
application:openURLs: only fires when a document was named. The net
effect: the Dock icon would appear, but no window ever showed.

applicationShouldHandleReopen:hasVisibleWindows: is exactly the
callback AppKit fires for this reactivation case. Reproduced and
verified the fix against the real sequence (cold launch, kill only the
GUI process to simulate Cmd+Q, reopen) rather than assuming it from
the delegate method's docs alone.

Felix RiestraandClaude Sonnet 5 e767507850 macOS: add a launcher shim so a cold Finder open also works (#1039)
The previous commit's Apple Event handler only ever catches an open
sent to an already-running process. A cold double-click (app not
running yet) still failed: every registration point tried inside the
real binary — before app::run(), on the Subscription's first poll,
even the literal first statement of main() — reliably caught a warm
open but never the original cold-launch event. A raw
AEInstallEventHandler in a separate, minimal, non-AppKit process (no
winit/iced, just a manual CFRunLoopRunInMode pump) still missed it
too, ruling out "the real binary's heavy dependency graph loading
before main() wins the race" as the explanation.

What does reliably catch a cold launch, verified against real
Finder-equivalent opens: a from-scratch NSApplication with its own
delegate implementing application:openURLs: — in a process where we
own setDelegate: from the start, with no contention over the single
delegate slot winit already claims. That has to be a separate process
from the real GUI binary (only one -[NSApplication run] call can own a
process), so src/bin/ocs_launcher.rs is now the .app's actual
CFBundleExecutable: a small, dependency-light binary (no iced, wgpu,
or cadkernel) whose only job is to catch the open and relay it.

Relaying by replacing this process's image (exec, same PID) or by
spawning a child and exiting turned out to both be dead ends: Launch
Services tracks "the running instance of this bundle" by the
Application Serial Number it handed out to whichever process it
actually launched — this launcher, not whatever it execs into or
spawns. Once the launcher's own ASN stopped pointing at a live,
listening process, every later open Finder tried to deliver silently
went nowhere (measured with lsappinfo against a real second "Open
With", not assumed). So the launcher now stays running for the app's
session — invisible, via NSApplicationActivationPolicyAccessory, since
it owns no window — and relays every open (cold or warm) over the same
channel a second CLI invocation already uses: io::single_instance.

That relay only worked once single_instance's rendezvous key stopped
being computed from the running executable's own path. That was fine
when one binary always did the job, but the launcher and the real
binary are different executables and independently computed different
ports, so they could never find each other. Anchor the key on the
enclosing .app bundle instead, shared by both.

packaging/build_macos_signed.sh and .github/workflows/release.yml now
build ocs_launcher and place it at Contents/MacOS/OpenCADStudio (the
CFBundleExecutable Info.plist already names), with the real GUI binary
renamed to Contents/MacOS/OpenCADStudio-App alongside it.

Felix RiestraandClaude Sonnet 5 b617734d5c macOS: catch a Finder open aimed at the already-running app (#1039)
Double-click / "Open With" never puts the file on argv — Finder always
delivers it as a kAEOpenDocuments Apple Event instead, which nothing in
this app listened for, so it just showed "cannot open files in this
format" even though the file association itself was registered
correctly.

The standard fix, implementing application:openURLs: on this app's own
NSApplicationDelegate, isn't available here: winit already installs
its own delegate to own window/lifecycle events, NSApplication has
exactly one delegate slot, and winit's class doesn't implement the
open-document method.

This bypasses the delegate protocol and registers directly with the
lower-level Apple Event Manager (AEInstallEventHandler) instead — the
same mechanism AppKit's delegate forwarding is itself built on, and
independent of who owns the delegate. Registration happens on the
iced Subscription's first poll rather than in main() before app::run()
— registering earlier gets silently overwritten by winit's own
NSApplication startup, confirmed by testing against a real `open -a`
rather than assumed from Apple's docs.

This handles a file opened while the app is already running. A cold
launch (app not running yet) needs a different mechanism, in the
following commit.
