Tommaso BianchiandClaude Opus 5 498e92ee35 The gate covers the rounded rectangle, and stops tripping over the plug-in modal
Two harness fixes, both paid for by hours of chasing product bugs that were not there.

ROUNDED RECTANGLE. It is the shape the user reported and the gate could not reach it:
the rectangle family binds R to CornerRect and leaves the other modes in the toolbar
flyout, so the three-step Width -> Height -> Radius chain was never exercised.
rung_rounded_rect() arms it over MCP the way the offer menu does. The verb id is the
OFFER id `sk_rect_rounded` — `design_rect_rounded` is the ACTION name, run_verb
throws on it, and the tool silently stays Select; a run that misses that draws
nothing and still reaches its assertions, so the rung arms AND verifies.

THE NETWORK PLUGIN MODAL. GUI_App::post_init() re-raises "Bambu Network Plug-in
Required" from an IDLE event, after any startup sweep has closed it, and
ShowModal() runs a nested event loop: the app is alive, its window is on screen,
and the MCP socket answers nothing. That is indistinguishable from a hang and was
investigated as one, with gdb, twice — the attached stack finally read
ShowModal <- show_network_plugin_download_dialog <- post_init. Seeding
`installed_networking` false stops the whole networking path, so the dialog never
exists to be swept.

Also: check() returns its verdict, so a rung can abandon itself when a precondition
fails instead of asserting into a dead end.

38 checks hold on behemoth against e5659e0f0f.

Tommaso BianchiandClaude Opus 5 1dff232f0b The gesture ladder stops clicking the field before it types
check-gui-sketching.py located the value field by hunting for a small top-level
window and clicked into it before typing. Both halves are now wrong, and the second
was always a problem:

 - field_win() cannot find a field that is not a window any more, so every check
   built on it silently became one that cannot fail. Replaced by field_open(),
   which asks the app: sketch_describe's `editing` is value_field_open().

 - focus_field() clicked into the field first, and its own docstring said why —
   "WITHOUT THIS THE TYPED VALUE IS SILENTLY DISCARDED". That workaround is exactly
   what made this suite blind to the defect the user reported: a ladder that clicks
   the field first can never notice that typing WITHOUT clicking is broken. Now a
   documented no-op; the field is in the canvas and the canvas has the keyboard.

Measured on behemoth against e5659e0f0f: 64 checks pass, 2 fail. The two are
polygon regularity and area (sides {29.999986, 29.975164, 30.0}, area 2336.98 vs
2338.27) — geometry tolerances, nothing to do with typed values; before this change
the same run failed 5, all of them dimensions and constraints that never received
their value because focus_field() was clicking at a window that no longer exists.
No baseline exists for the remaining two, so they are reported, not claimed as
pre-existing. The suite also still stops at D3 with the app gone; tracked separately.

Tommaso BianchiandClaude Opus 5 e5659e0f0f The value field stops being a window, and now takes what is typed
Rebases the in-canvas work onto cad-mainline and finishes it. The field is drawn
by ImGui inside the GL canvas instead of being a borderless top-level wxFrame.

WHY THE FLOATING FRAME COULD NOT BE FIXED. Whether a borderless top-level may hold
the keyboard is the window manager's decision, and it differs per desktop: openbox
grants it, mutter refuses it, macOS denies key status outright. Seven workarounds
fought that and one cost a macOS regression. Drawn inside the canvas there is no
second top-level for anyone to refuse, so the question is never asked. The field is
fed exactly like every other ImGui widget in the app — GLCanvas3D::on_char ->
ImGuiWrapper::update_key_data -> io.AddInputCharacter.

MEASURED, on behemoth: the click-edit ladder holds 28 checks — Line, Rectangle,
Circle, Slot, Polygon, Ellipse, Arc, and click-to-edit on a placed dimension label
— typing with NO click into the field first, committed == typed != prefill every
time, and 27 [UX] imgui_char lines showing the characters arriving.

WHAT WAS ACTUALLY WRONG. Not the field. The belief that "characters never reach the
ImGui InputText" came from the harness: the ladder was delivering keys with
`xdotool type --window` (XSendEvent), which GTK discards, so no build of any kind
could have received them. The new probe in ImGuiWrapper::update_key_data — the one
place ImGui is ever handed a character — is what separated that from a real defect,
and it stays, because a canvas-side probe provably cannot answer the question:
GLCanvas3D::on_char is bound later than any constructor-time probe, wx runs handlers
in reverse bind order, and on_char returns without Skip(), so such a probe is silent
whether or not the key arrived. A day was lost reading that silence as evidence.

Also drops DesignPanel's content-based forwarder and DesignCanvas::inline_type_char.
They were the right rule for a field that could not be focused; with the field
inside the canvas there is nothing to forward, and keeping them would have masked
whether the normal path works.

STILL UNVERIFIED: behaviour under mutter itself. Neither focus-stealing-prevention
WM available here survives long enough to judge — metacity SEGVs ~20s in and xfwm4
dies with BadWindow on SetInputFocus, both before the sketch opens and both
unrelated to this field. The design's claim is structural rather than measured: no
second top-level means no focus to refuse.

Tommaso BianchiandClaude Opus 5 9134299233 Sketch value fields: content-based key arbiter + the gate that can judge it
The reported defect: sketch dimension labels are "not editable" — you draw a
rectangle, its Width field opens, you type, and the as-drawn number is committed
instead. It affects every sketch tool, not just the rounded rectangle.

WHAT THIS ADDS

1. The arbiter (DesignPanel CHAR_HOOK -> DesignCanvas::inline_type_char ->
   SketchInlineEditor::type_char). Routes a key by what it IS, not by who the
   window manager focused: digits, sign, decimal separator and Backspace/Delete
   go to the open value field, Enter/Tab commit, letters stay tool shortcuts.
   This is FreeCAD Sketcher's rule (DrawSketchKeyboardManager::
   detectKeyboardEventHandlingMode), and the reason its sketcher behaves the same
   on every desktop: it never asks who has focus.

2. The [UX] trace (SNAPORCA_UXTRACE) in SketchInlineEditor: open/commit/refused/
   cancel, with the prefill and what the control actually held at Enter. It did
   not exist — the ladder below was written against a surface no build emitted,
   so it could only ever report "nothing opened". typed == prefill on a commit is
   the defect's signature and nothing else makes it visible.

3. A draw-then-edit trace in DesignSketchTool: four early returns can swallow the
   value-field chain and from outside they are indistinguishable.

4. scripts/CAD/check-gui-click-edit.py — types WITHOUT clicking the field, as a
   person does, across Line/Rectangle/Circle/Slot/Polygon/Ellipse/Arc plus label
   click-to-edit, and asserts committed == typed != prefill.

5. scripts/CAD/focus-loop.sh — sync/build/assert on behemoth. NOT the orcacad-gui
   rig: its image pins deps 216 non-CAD files behind cad-mainline, so today's CAD
   sources cannot build there without a deps rebuild.

WHAT IS PROVEN, AND WHAT IS NOT

Green under openbox: 28 checks, every tool, committed == typed != prefill.

But openbox CANNOT adjudicate this bug and the ladder says so in place. There the
field always wins the keyboard, so the same ladder also passes against a binary
with the arbiter compiled out — measured twice. Two ways of removing the keyboard
were tried and both are recorded as dead ends: XSetInputFocus loses to the field's
own re-focus CallAfter, and XSendEvent (xdotool --window) is dropped by GTK, which
made every run red regardless of the code.

Under metacity — same focus-stealing-prevention lineage as the user's mutter — the
mechanism appears in the WM's own log:

    Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0

That is the activation being refused, which is exactly the reported symptom.
present_toplevel() already asks for a server timestamp, so a path is still falling
through to frame->Raise(), which sends time 0. That is the next thing to fix, and
it is tracked; the arbiter alone does not close it. metacity also aborts on this
window (frames.c:1239), so the gate needs a WM that survives before it can return
a verdict.

Tommaso Bianchi 8b9ff36685 The eleven constraint buttons no rung had ever pressed
Twenty buttons on the CONSTRAIN bar, nine of them exercised. The other eleven
were "implemented" in the sense that the kernel builds the right def for them --
which is exactly what was true of Parallel yesterday morning, right up until a
user pressed it and got nothing.

What a kernel test cannot see is whether the BUTTON is wired to the index its
name claims. CON_BTN is 449 + 42*i over a hand-written name list, and it has
drifted once already: six buttons were inserted, everything from index 6 on
pointed at the wrong control, and nothing caught it for months because no rung
pressed past index 5. D13 presses index 6; D14 through D22 press 8 to 19. The
map turned out to be intact, which is worth knowing rather than assuming.

D12 vertical, D13 equal_radius (its own button, not Equal's promotion),
D14 concentric, D15 tangent, D16 midpoint, D17 symmetric (the three-pick form),
D18 sym_h, D19 radius, D20 diameter, D21 fix, D22 dist_y.

Three are shaped around a specific way the code could be wrong rather than
around "does something happen":

  D20 exists for a factor of two. Diameter wired to the Radius handler gives
  r = 30 for a typed 30, and nothing on screen looks wrong.

  D21 -- Fix alone is unfalsifiable: nothing moved, so nothing proves the
  constraint exists. It only becomes observable when a SECOND constraint would
  otherwise move the fixed point, so the rung drives the pair to a 70 mm gap and
  checks which end travels.

  D14 asserts the radii did NOT change. Concentric is about centres; a solve
  that also equalised the radii would pass a naive check.

D17 failed on its first run and the rung was wrong, not the app: all three
entities are free, so the solver is entitled to satisfy the mirror by moving the
AXIS instead of the points -- and it did, landing the pair symmetric about
x = -8.18. It now measures signed perpendicular distance to the axis where the
axis actually is, which is the stronger property anyway.

Coverage: 20/20 buttons pressed, up from 9. Ladder 135 -> 177 properties across
43 rungs, all holding.

Tommaso Bianchi 8f3f835636 Constrain while you sketch, and stop losing work to Esc and to invisible points
Five defects from ten minutes of real use, and the mode split behind the worst
of them. One commit because the changes overlap in the same functions; the
pieces are separable in the diff, not in the file.

CONSTRAINING NO LONGER NEEDS A COMMITTED SKETCH. A constraint could only be
applied by committing the sketch, selecting it in the feature tree, pressing the
padlock, and only then picking. While drawing, the CONSTRAIN toolbar was not even
on screen (set_ui_mode showed it in UiMode::Constrain alone) and apply_constraint
answered "Press Constrain on a sketch first" -- in a status line nobody looks at.
Draw two lines, press Parallel, get nothing: that is what a user reported as "the
UX is a mess", and they were right.

apply_constraint now takes the live session first, reading the picks from the
selection model the sketch tool already had (click, ctrl-click to extend,
double-click for the loop) and applying through try_add_constraints, which
already did append -> solve -> keep-or-rollback. The committed Constrain path
stays for editing an old sketch; it is no longer the only way in. The twenty
constraint buttons now show in Sketch mode as well.

The discriminator is is_sketching() && !is_constraining() &&
!is_constraining_entities(). Both begin_constrain and begin_constrain_entities
set m_active, so is_sketching() alone is true DURING a constrain session and the
new path would hijack the old one -- compiling perfectly and failing in
behaviour.

ONE PLANNER, NOT TWO. A second caller meant duplicating the logic that decides
whether a constraint is legal, which roles it binds and whether it needs a typed
value. That duplication is how today's Coincident bug survived: fixed in one
branch, alive in the next one down. plan_entity_constraint() now lives in the
kernel -- pure, no wx, no translation -- and both UI paths call it. DesignPanel
loses 304 lines and gains 155.

Being in the kernel makes it TESTABLE. The Parallel defect existed because a
constraint type met an entity type nobody had tried, and the only instrument was
a 13-minute GUI ladder. 19 new kernel cases cover the matrix: 264 -> 283 cases,
7648 -> 7867 assertions.

Parallel, Perpendicular and EqualLength gain the two-line guard they never had.
On non-lines they used to emit a def the solver silently dropped -- the sketch
reported itself constrained when it was not, the same class as Horizontal on a
Point. EqualLength on two rounds still promotes to EqualRadius first.

Symmetric is planned completely, including its axis pick: the plan carries a
VECTOR of defs because Symmetric on two lines is two constraints (P0/P0 and
P1/P1). A single def would have half-applied it -- one end pinned, one free,
looking correct until something moves.

A PLACED POINT SURVIVES THE COMMIT. Type::Point was created correctly and never
drawn once committed: both renderers skip it, correctly, since entity_polyline
gives a point nothing. What was missing is the vertex-marker path the live
session already used. rung_point passed throughout because it asserts the
document, and the point was always in the document -- the pixels lied.

ESC STOPS EATING AN UNSAVED SKETCH. The third press reached cancel_sketch(),
clearing m_entities with no warning and nothing to undo. live_sketch_has_work()
existed and was never consulted. The exit layer refuses once when there is work
and lets a second consecutive Esc through; the refusal re-arms on a button press,
never on mouse motion, or Esc could never exit while the hand moves.

TWO NEW RUNGS. D10 drives Parallel through the committed path -- it passes on
the PRE-fix binary, which is how we know the user's failure was the mode and not
the constraint. D11 is the acceptance for the collapse: draw, pick both, press
Parallel, no commit and no padlock. Ladder 126 -> 135 properties, all holding.

CON_BTN_SKETCH is measured, not derived: in Sketch mode the group renders after
the sketch toolbar, so the first button is at 677, not 449. Pitch 42, twenty
buttons, read off a screenshot. Deriving it by offset is how that table drifted
the last time.

Known limit, commented at the call site: a constraint added to a LIVE sketch is
not on the document undo stack, so Ctrl+Z will not take it back until the sketch
is committed.

Tommaso BianchiandClaude Opus 5 cd30fb891e the same phantom-endpoint bug in Coincident, and the two unguarded branches next to it
Port of snaporca da8d011b87; parity holds (DesignPanel.cpp still exactly 32 divergent
lines). Verified independently on this fork's own rig: full ladder 126/126 against
BuildID 96c697a3, built from this tree.

Reviewing the DistanceX/Y fix for OTHER members of its class found three more live defects
on the constrain toolbar. All four share one root: a branch assumes every picked entity has
two endpoints, and the solver's refusal to resolve a role it cannot find is silent.

COINCIDENT had the identical closest-pair walk over {P0,p0},{P1,p1}. For two Points the
phantom (0,0) pair sits at distance 0, which is the smallest distance there is, so it
ALWAYS won: ptOf(Point,P1) -> 0, ref_ok fails (SketchSolver.cpp:185), constraint dropped.
Not sometimes -- every press.

HORIZONTAL/VERTICAL hardcoded ra=P0, rb=P1 with no type check. With a Point picked the
constraint is dropped by the same mechanism but still STORED: constraints goes 0 -> 1 after
the commit and nothing moves, so the Constraints list shows a dimension that can never do
anything. Worse than refusing -- the panel claims the sketch is constrained when it is not.

ANGLE computed p1-p0 on whatever was picked. On a circle that is (0,0)-centre, so two
circles pre-filled the field with the angle between their centre POSITION VECTORS (178.83
deg for two on the x axis), and accepting it emits SLVS_C_ANGLE on two circle prims.

Both branches now refuse with a message. entity_ends()/closest_ends() are file-scope and
shared by Coincident and DistanceX/Y, so there is one implementation instead of two that
drift.

Two smaller findings from the same review: infer_auto_constraints' roles_of omitted
EllipseArc while heal_coincidences' identical copy has it; and set_point(Circle, Center)
wrote e.center and not e.p0, breaking the "p0 mirrors centre" invariant for the duration of
a live drag.

New rungs D8 and D9, both RED against the shipped binary and green here.

Tommaso BianchiandClaude Opus 5 afb17e8889 D3 was testing luck: the pair started 3 degrees from square, inside inference's snap
Port of snaporca b3221f8a12; this is the fork the fault surfaced on.

The perpendicular rung drew its two lines 93.5 degrees apart and then asserted they did
NOT start perpendicular. On this rig, whose camera maps the same click a pixel differently,
they arrived at exactly 90.000000 -- inference had already done the job the rung exists to
test, so the precondition failed while every later check passed. Held on the other fork and
failed here from identical source: the rung depended on where a click happened to land, not
on the app.

The second point now starts the pair 56 degrees off, well outside any snap tolerance, so
the button has real work to do.

That immediately exposed a second, milder fault in the same rung. From a 51 degree start
the LIVE solve converges to its own tolerance and lands at 89.999999991; the old 1e-9
assertion held only because the correction used to be tiny -- it was measuring how little
work the solver had to do, not whether the lines came out perpendicular. It is 1e-6 degrees
now, which is 1.7e-8 radians. The round-trip check still demands exactly 90 and gets it,
because the committed feature re-solves from scratch.

Full ladder 118/118 on BOTH rigs after this, each driving its own fork's binary. This fork
had never had a green gesture ladder before today (snaporca-eoj1).

Tommaso BianchiandClaude Opus 5 d35d33971a the feature-tree row needs CHROME_DY too — the last chrome constant that did not carry it
Four of this fork's five absolute chrome coordinates were shifted by CHROME_DY when the
ladder was first brought up here (DESIGN_TAB, CONSTRUCTION_CHECKBOX, CON_BTN_Y,
CONFIRM_BTN). TREE_ROW0 was not, because it is declared above the CHROME_DY block and was
simply never in view.

The unshifted click lands 26 px below the first tree row, just past its 23 px height, so
the row is never selected and Delete does nothing. reset_document then spends 40 rounds on
it and dies with "could not empty the feature tree" — a message that names the feature
tree, which is not the fault. The same 26 px is why confirm_and_reopen's double-click did
not reopen the sketch, which surfaced as "sketch_describe: no sketch is open" three frames
away from the cause.

Measured, not inferred: the Sketch1 row centre reads y=241 on the rig at 1920x1080 with
the window at (0,0), against the constant's 215. CONFIRM_BTN was checked in the same pass
from a screenshot taken in CONSTRAIN mode and is correct at (1751, 101).

With this, the four new constraint rungs hold 20/20 on this fork's rig, driving the binary
built from 648b930e75 (BuildID 56417445) — so the DistanceX/Y fix ported here is now
exercised, not merely parity-checked.

Tommaso BianchiandClaude Opus 5 648b930e75 gesture rungs for the six new constraint buttons, and the DistanceX/Y bug they found
Port of snaporca 2951e3c60b; parity holds (17 identical, DesignPanel.cpp still exactly 32
divergent lines, so the hunk landed on the right side of the DropDown divergence).

The sketch-constraint epic added six toolbar buttons and covered all six with kernel
tests. Not one of them was ever clicked. The gesture ladder only pressed 'perpendicular'
and 'equal' -- and CON_BTN, which locates buttons by index, was silently wrong for every
entry past index 5 for the whole epic. The untested half of the toolbar was exactly the
broken half (snaporca-rqsy).

Four rungs now drive them: D4 Equal on two circles (must mean equal RADIUS, not the
equal-length no-op the epic fixed), D5 Collinear on two oblique lines, D6 a horizontal
distance, D7 symmetric about the implicit vertical axis. Full ladder 118/118 on snaporca;
this fork's rig has not been rebuilt against the change yet, so here it is reviewed,
parity-checked and NOT exercised.

D6 found a shipped defect. apply_entity_constraint enumerated {P0,p0},{P1,p1} for BOTH
entities regardless of type, but a Point's p1 is unused and reads (0,0), as does a
Circle's. The closest-pair search then picked those two phantom origins, distance 0: the
field opened pre-filled 0.00 and the solver dropped the constraint, because ptOf(Point,P1)
resolves to no handle. Nothing errored -- the dimension simply did nothing. ends_of() now
enumerates only the roles an entity actually exposes, and the pair with no point at all is
refused with a message instead of a silent no-op.

Five kernel tests, a 7/7 ladder, a review and a fork port all passed over this, because
every one of them exercises the kernel, where the geometry was always right.

Two rig faults fixed in the same pass, both of which produce a green-looking session that
tests nothing: start-headless-gui.sh never exported SNAPORCA_MCP or SNAPORCA_KEYTRACE, so
a freshly launched rig comes up healthy and every ladder dies on "Connection refused"; and
it never dismissed the "Restore" dialog a killed session leaves behind, which grabs every
synthetic click afterwards.

The value field also takes no keyboard focus from the WM -- typed digits go to the canvas
and Return commits the pre-filled number (typed 40, got 54.94). focus_field() finds it as
its own top-level window and clicks it first. The no-op tolerance is now 5e-3, the field's
own two-decimal display resolution, not 1e-6.

Tommaso Bianchi d0791c3b8a Make the ladder runnable on this fork's rig — 6 of 7 rungs now hold
This fork had never been gated end to end. Five separate things stopped it, none
of them a defect in the CAD code itself, and each failure named the wrong
subsystem — which is why they survived.

1. run-all-checks.sh invoked docs/ux/mockups/gen_offer_table.py. The design docs
   moved to docs/CAD/ (bbd1989e1e) and this path did not follow, so the rung
   failed on a missing file.
2. gen_offer_table.py then resolved REPO one dirname short, because it now sits a
   level deeper. OUT pointed at docs/src/.../DesignOffer.hpp, which does not
   exist, so --check diffed the generated table against an EMPTY file and
   reported all 189 lines as a difference.
3. DISPLAY was never passed into the container. The check scripts fall back to
   ":10", which is the other fork's rig; this one's Xvfb is :11. Symptom:
   "FATAL no app window on :10", which reads like a dead app.
4. Every absolute chrome coordinate was written in the Snapmaker fork's layout.
   This fork keeps mainline's top row (File / save / undo / redo / Calibration
   with the title), so the whole chrome sits 26 px lower. At the unshifted y the
   Design-tab click landed in the toolbar and the app stayed on the Home page,
   reported as "no sketch opened after plane click + Shift+S"; the unshifted
   Construction checkbox reported "0 construction axis". The three constants now
   derive from CHROME_DY. Canvas coordinates were never affected -- clickmm()
   computes them from live canvas geometry -- which is why dozens of geometric
   properties passed exactly on a GUI that had never been driven.
5. CON_BTN was stale for every index after 5, from the sketch epic's six new
   buttons. Fixed in both forks; see the companion commit on snaporca.

pdftocairo was also missing from the rig image (installed there, not a repo
change), without which every corpus sheet threw.

RESULT: offer-table, kernel, engine, corpus, corpus-scale and offer all hold.
The gesture ladder now reaches D2 and applies Equal length through the Constrain
toolbar, both sides landing at 99.928133658; it then fails re-entering the sketch
after commit, filed as snaporca-eoj1 with the evidence and the next measurement
to take. Kernel here is 7701 assertions / 270 cases.

Tommaso Bianchi fac3cf44df Infer parallel, perpendicular, equal radius and tangent while drawing
Port of snaporca 2d36d28770. Parity OK: 17 files identical, 8 diverging at their
expected counts.

infer_axis_constraint returned only Horizontal or Vertical. On the
CAD-1000-hours corpus the top two transitions are sketch_dim -> sketch_draw
(5896) and back (5756): the signature of geometry that does not self-constrain
as it is drawn.

Every rule requires the relation to be ALREADY TRUE within tolerance, so nothing
the user drew is moved; parallel/perpendicular and tangent additionally require a
shared endpoint.

TWO LIMITS THE CORPUS RUNG FORCED, neither visible to the unit tests:

1. At most ONE constraint per rule per new entity, not one per PAIR, and no
   one-at-a-time fallback for the relations batch. EqualRadius has no locality
   restriction, so 200 equal holes produced ~20000 candidates; the rejected batch
   then cost a solve per constraint and pinned the app at 95% of a core with the
   MCP socket unresponsive.

2. Relations only for gesture-sized batches. "A scripted add is not a drawn
   gesture" is already this file's rule at its bulk call site (snaporca-8xg1), and
   EqualRadius also couples geometrically distant entities, merging independent
   connected components and defeating the partitioning that makes large sketches
   solvable (snaporca-yww4). With the cap alone geometry stayed correct (32/32
   sheets clean) but seven of the largest timed out, including MPD681 -- the sheet
   that call site's own comment names.

Also fixes the tolerance leak behind 2: the bulk path asks for exact inference
with ang_tol_rad = 0 but len_tol_frac kept its 0.01 default.

ALSO independent of this feature: run-kernel-tests.sh defaulted to
TAGS=[CadDocument] while four CAD test files carry their own tags and nothing
selected them (2624 assertions / 206 cases reported, 7648 / 264 actual). All 58
dark cases were passing; the coverage was never exercised.

VERIFICATION LIMIT, as with the previous three commits: this fork's kernel suite
still cannot run (find_package(assimp) at configure time, snaporca-w80c). Shared
sources are byte-identical to snaporca's, where kernel is 7651 assertions / 265
cases and ALL LADDERS HELD 7/7.

Tommaso Bianchi a1f2a2687a Equal radius and Collinear, and one Equal button that knows what it picked
Port of snaporca 9ec6405e2d. Parity OK: 17 files identical, 8 diverging at their
expected counts (DesignPanel.cpp 32, test_slvs_constraints.cpp 3).

Measured on the CAD-1000-hours corpus: 51.5% of observed CAD time is 2D sketch
work, and dimensioning/constraining alone is 31.9% -- the largest single class.
Two constraints every industrial sketcher has were missing here.

EqualRadius fixes a dead end rather than adding a feature. Picking two circles
and pressing Equal emitted EqualLength, which maps to SLVS_C_EQUAL_LENGTH_LINES
and constrains nothing on a curve: a silent no-op with no error. Equal is now
one button with two meanings, as in Onshape and SolidWorks.

Collinear emits PARALLEL plus PT_LINE_DISTANCE=0 rather than PT_ON_LINE, whose
internal valP param this libslvs port leaves at 0, drifting an already-collinear
pair.

Both types are appended at the END of SketchConstraintType: cereal serializes it
positionally, so inserting elsewhere reinterprets every saved recipe.

VERIFICATION LIMIT, stated rather than implied: this fork's kernel suite could
NOT be run. scripts/CAD/run-kernel-tests.sh fails at CMake configure time on
find_package(assimp), before any source compiles -- a pre-existing deps gap
(snaporca-w80c), not this change. The shared sources are byte-identical to
snaporca's, where the full gate passed: kernel 2588/195 and ALL LADDERS HELD
across all seven rungs.

Also fixes two defects in this fork's scripts/CAD/run-all-checks.sh:
  - `cd $(dirname $0)/..` landed in scripts/ instead of the repo root, so every
    rung looked for itself under scripts/scripts/. Broken since the script moved
    into scripts/CAD/; the three sibling scripts were fixed then and this was
    missed, so the gate has not run since.
  - C defaulted to snaporca-gui, the OTHER fork's rig container, so this fork's
    gate would drive snaporca's app and report green about the wrong binary.
    run-kernel-tests.sh:31 documents the identical defect being fixed once
    already for the build volume; this is the third instance.

Tommaso Bianchi 13d5eac891 Move the Design-tab scripts into scripts/CAD/ and name them by role
Requested by SoftFever on PR #15238: ten of these had accumulated loose in
scripts/ next to ~20 unrelated upstream ones, with names that only meant
something to whoever wrote them. They now sit in scripts/CAD/, mirroring the
src/libslic3r/CAD/ and src/slic3r/GUI/CAD/ split, and the verb in the name is
the role: build- produces a binary, start- brings something up, run- runs a
suite, check- asserts one thing against a live app.

  kernel-test.sh        -> CAD/run-kernel-tests.sh
  ladder-all.sh         -> CAD/run-all-checks.sh
  sketch-ladder.py      -> CAD/check-sketch-engine.py
  ladder-corpus.py      -> CAD/check-sketch-engine-corpus.py
  gui-ladder.py         -> CAD/check-gui-sketching.py
  offer-ladder.py       -> CAD/check-gui-context-menu.py
  mcp-sketch-smoke.py   -> CAD/check-mcp-sketch.py
  rig-build.sh          -> CAD/build-gui.sh
  docker-iter-build.sh  -> CAD/build-gui-incremental.sh
  gui-session.sh        -> CAD/start-headless-gui.sh

"Ladder" was the worst of them: it named the shape of the test (rungs of
increasing difficulty) rather than what the test proves, so nothing in the
directory listing told you which one needed a GPU and which was pure kernel.

Every reference rewritten -- the docs, the cross-calls between the scripts,
Dockerfile.deps, and the container-side /OrcaSlicer/scripts paths. The three
shell scripts resolve REPO relative to themselves and now sit one level
deeper, so that walk went from /.. to /../.. . The copies these push into a
container's /tmp were renamed to match, or the container would have kept the
old names alive.

Two runtime paths deliberately NOT renamed. /tmp/orca-rig-build.lock is a
cross-fork contract -- both forks take the same lock so two concurrent builds
serialise instead of OOMing the box, and renaming it on one side silently
removes that guard. /tmp/gui-session.log is a runtime artefact, not a script.

Added scripts/CAD/README.md: what each script proves, what it needs, and the
two constraints that have each cost a session (never build inside the GUI
container; a window manager is required or synthetic keys are ignored).

On CI, which was the other half of the request: the kernel suite is already
there and always has been. The cases are registered in
tests/libslic3r/CMakeLists.txt under if (SLIC3R_CAD), which defaults ON and no
workflow turns off, so they build into libslic3r_tests and run under ctest on
every platform via unit_tests.yml -- like any other unit test, needing no new
job. They have simply never been seen to run, because the workflows on this PR
are still awaiting maintainer approval. run-kernel-tests.sh is the local loop
over the same cases, and it is the only script here CI could run: the other
six need an OpenGL canvas and synthetic input.

Verified: scripts/CAD/run-kernel-tests.sh from its new location, all tests
passed, 2562 assertions in 190 test cases.
