The gesture ladder proved the TARGET — a complex closed profile, exact in vertices, lengths, arcs
and symmetry, voids correctly attributed. It proved it by arming every tool with a letter key,
which leaves the goal's own MECHANISM untested: the design logic pivots on right-click, and the
verbs offered are supposed to adapt to the element under the cursor. 47 of 86 Design-tab verbs
have a GUI action and no shortcut, so a key-driven ladder cannot reach more than half of them.
scripts/offer-ladder.py drives the menu. It asserts nothing from pixels: show_offer_menu emits an
[OFFER] trace from the same loop that builds the rows (behind the existing SNAPORCA_KEYTRACE), so
what the ladder reads cannot drift from what the user is shown, and the expected row set is
predicted by parsing DesignOffer.hpp rather than transcribed by hand. 25 properties, four rungs:
what each element type offers, that the menu equals the table for four selections AND that the
four differ, a 120 x 80 profile authored entirely through the menu, and a tool with no keyboard
route at all driven from the only door it has.
Two real defects, both found by it, both fixed here:
snaporca-ghcz (P1) — right-click was a black hole while any draw tool was armed. Every draw case
ended with `if (evt.RightDown()) { m_points.clear(); return true; }` and returned true even with
nothing to abandon; on_mouse records that in m_right_consumed and DesignCanvas suppresses the
offer whenever it is set. Measured: with Line armed, two right-clicks in a row produced no menu
and no tool change; only Escape freed it. Same rule snaporca-xmh6 wrote for the selection —
clearing nothing is not a gesture terminator. One shared right_abandon() now consumes the click
only when an anchor was really down; 16 sites, plus Polyline/BSpline (which end a chain, correct
only when there IS one) and Point (which has no anchor at all).
snaporca-lnri (P2) — right-clicking a sketch point offered the empty vocabulary. select_at_screen
tests hit_test_point first and records the hit in m_point_sel, but the offer counts m_selection
only, so a Point entity could never reach the entity branch and SkPoint was unreachable by
construction. A Point IS its own handle, so it is selected as an entity; other entities keep the
handle pick, since a line's endpoint is a drag target, not a vocabulary.
Offer ladder 25/25, gesture ladder 93/93 (no regression), both on the rig. The offer ladder joins
scripts/ladder-all.sh as the fifth rung.

Draw-then-edit is armed from a jump in the entity count: render() sees n > m_autoedit_seen,
selects the last entity and schedules open_primary_autoedit. A scripted add made while a
creation tool was armed looked exactly like a drawn gesture, so it opened that tool's value
field — and an open field freezes the canvas (on_mouse_impl returns early on m_awaiting_length)
and swallows every letter (in_text includes inline_busy()). Measured on the rig: after
sketch_add, 'p' + click added nothing (4 entities before, 4 after); one Escape and the identical
sequence gave 5. It also explains the selection = [last index] that sketch_describe reported
although action_sketch_add never selects anything — the render pass wrote it.
Escape worked because it sequences two set_tool calls: the pending CallAfter fires between them,
so the second one commits the field it finds open. Arming a tool directly is one call, and the
CallAfter fires after it.
Fix: resync m_autoedit_seen at the end of add_entities_scripted, so a scripted add is not read as
something the user just drew. An already-open field is left alone. Covers sketch_add,
sketch_mirror and sketch_offset — the three callers.
The scale rung's Escape workaround is deleted, which is the issue's acceptance criterion; it is
now the regression test. Gesture ladder 93/93 on the rig.

Two commits carried across (snaporca 579a9a9162, f68613cfc5).
Past about 480 entities a sketch had NO constraints at all and said nothing: libslvs
declares MAX_UNKNOWNS = 1024 and is handed every entity in the sketch at two params
per point, so the whole system came back TOO_MANY_UNKNOWNS and try_add_constraints
rolled the entire inferred batch back. From there no dimension could ever be applied.
Constraints only couple entities that share a point, so the solver now falls back —
only on TOO_MANY_UNKNOWNS — to solving connected components separately and committing
all-or-nothing. The auto-constraint pass batches its Horizontal/Vertical constraints
instead of one solve each, which is what kept the bulk path fast once solves started
succeeding: a 1204-entity load went 1585 ms -> 562 ms.
Plus the scale rungs (a thousand-entity plate drawn on by hand; the heaviest real
drawings graded and timed), the --step 1 fix that used to select nothing while
reporting a clean run, and scripts/ladder-all.sh as the one-command gate.
Parity 17 identical / 8 diverging as expected. Kernel suite here: 188 cases /
2532 assertions, including "a sketch past the solver's unknown limit still solves".

and a ladder that draws with the mouse
Three commits carried across (snaporca 4ffd60eacb, 421055c2ec, b71216ce0b):
1. A design made only of sketches must survive being saved. CadDocument::recompute
returned false with "no solid-producing features" for a document that has no
solid, and two callers read that as "unusable": the GUI syncs the 3MF recipe
only after a successful recompute, so a sketch-only design was saved with no
recipe at all, and deserialize_recipe ends with `return recompute()`, so even a
project that carried one was refused on load. Having nothing to build is now a
success; a feature that MEANT to build a solid and produced none still fails.
DesignPanel::refresh_tree syncs the recipe too, for the paths that call
m_doc.recompute() directly.
2. Scripted geometry arrives exact. The Horizontal/Vertical inference window and
the endpoint weld window both close to zero for add_entities_scripted; void
attribution probes from a point strictly inside each loop instead of from its
first vertex. Corpus rung 39 graded / 39 fully clean, was 35 with 6 failures.
3. scripts/gui-ladder.py — 17 rungs, 84 properties, all driven by synthetic clicks
and typed values rather than through the socket.
Parity 17 identical / 8 diverging as expected. Kernel suite here: 188 cases /

Mouse3DController::apply DRAINS the input queue and every BOUND canvas idles and calls it, but a
hidden canvas's render() early-returns on _is_shown_on_screen() — so it swallows motion, applies
it to the shared plater camera, and draws nothing. The next visible frame jumps by more than one
state change. The plater keeps exactly one of its three views bound; the Design canvas binds once
at construction and never unbinds, so two canvases drain the same queue.
Guarded at the apply site so only the canvas actually on screen takes motion off the queue,
whatever happens to be bound, and without touching the plater's view-switching state machine.
Reported by exussum12 on PR #15238 as lag and jerkiness in the Design tab against "really smooth
on the other tab"; he guessed the mechanism correctly. NOT verified with a device — there is no
SpaceMouse here and the rig has no HID, so this is a mechanism traced in source and matched to a
user's description, not a measurement.

Carries snaporca 0231bd5b68. Parity holds: 17 files identical, 8 diverging as expected.
A reflection reverses orientation, so mirror_entities now hands the reflected half back reversed
in ORDER and flipped per ENTITY — an arc swapping its angles as well as its ends, a spline
reversing its control points. Appending it to the source then yields one walkable chain instead
of two halves meeting head-to-head, and a mirrored CCW loop stays CCW.
This is the producer half of the confusion that cost three defects; the consumers (offset, and
the exact loop area) keep their defensive handling, because that is what makes them correct for
hand-built and imported sketches rather than only for geometry this function produced.
Contract change, carried with the reason: a mirrored line's p0 is the reflection of the SOURCE's
p1, and a mirrored CCW arc keeps a POSITIVE sweep — the reflection negates it, walking it the
other way negates it again. Both [SketchEdit] cases updated, and a new [SketchProfile] case
"a mirrored half continues the original chain" pins the property directly.

identical, 8 diverging by their expected counts.
EXACT AREA. A loop's area is now integrated entity by entity in traversal order — Green's
theorem — instead of being shoelaced over the render polyline, which faceted every arc into 24
chords and lost 2.02 mm2 on a 3706.86 mm2 stadium. 0.054%, invisible on screen, and wrong in a
number reported as "the area".
OFFSET FOLLOWS THE TRAVERSAL. Offsetting a mirrored profile put one half on the wrong side and
split the loop in two, because the chainer only followed p1->p0 links and each entity's offset
side was taken from its stored direction. Chains are now orientation-aware, seeded at a free end,
offset by `reversed ? -d : d`, and normalised head-to-tail on the way out — so offset is correct
for any input ordering and its own output cannot reintroduce the problem.
Both are the same underlying lesson, which has now cost three separate defects: an entity's
STORED direction is not its direction of TRAVEL around the loop.
THE LADDER. scripts/sketch-ladder.py is a graded suite of 2D sketches judged the way a person
judges them — VERTEX, LENGTH, ARC, TANGENT, SYMMETRY, CLOSED — with area only as a cross-check,
because area is derived and nobody can confirm it by eye. Eight rungs from a rectangle up to
MPD5 from the StudyCadCam corpus, a dia 27 x 95 pin reproduced as its revolve half-profile with
the R5 fillet tangency solved exactly. Entirely 2D: no extrude or any solid feature.

Carries snaporca 95e59289f9, faec177d42 and 20df726ecb. Parity re-verified: 17 files identical,
8 diverging by their expected counts — DesignCanvas.cpp back to 16 and DesignPanel.cpp back to
32, which is the proof each hunk landed on the right side of the FeatFlyout and TAB_ID_PREPARE
divergences rather than on top of them.
All three answer exussum12's review on OrcaSlicer PR #15238.
ENTER/ESC IN THE VALUE FIELD. The field is a borderless always-on-top frame, and whether it may
hold keyboard focus is the platform's decision — a borderless NSWindow can never be key, and
mutter refuses a re-mapped window. When focus is denied the keys reach the panel instead and the
queued-dimension chain (a line queues Length then Angle) cannot be walked. The CHAR_HOOK now
forwards Enter/Numpad-Enter/Tab/Esc to the field when it is open and unfocused, and stays out of
the way when it is focused.
ESC FROM ANYWHERE. Separately and more simply: `dismissable` is false throughout sketch mode
because m_active is the FEATURE tool, so Esc fell through to whatever widget had focus. Click
any toolbar button or the Construction checkbox first and Esc did nothing at all — the likelier
reading of "Esc hardly ever works", and platform-independent. DesignCanvas exposes
request_sketch_exit() and the hook calls it whenever a sketch is live, after the inline-field
forwarding so an open field still takes Esc first.
RENAME. wxTR_EDIT_LABELS plus the two label-edit events write through to CadFeature::name and the
recipe, with a Rename verb in the offer and F2. The rebuild is deferred with CallAfter because
refresh_tree() destroys the very wxTreeItemId wx is holding during END_LABEL_EDIT — inline, it
killed the process.
STALE PICKS. set_tool now drops the Dimension tool's first pick, the Constrain picks and
m_point_sel, and delete_selected clears the pending dimension reference that could otherwise
dereference a renumbered entity.

Carries snaporca 39fac9b725. Parity re-verified: 17 files identical, 8 diverging by their
expected counts, DesignPanel.cpp still at 32 — the mirrored files were copied and the two
divergent ones patched hunk by hunk, so the counts returning to their expected values is the
proof each landed on the right side.
All 90 offer verbs are now firable by name over the socket, which matters because a deck key
can only send a keystroke and 49 of them have no shortcut at all. sketch_set_value calls the
same apply_dimension the in-canvas value field calls, so a typed dimension can be asserted with
no window manager in the way.
Three guards came with it, each confirmed against the source: on_mass_properties bounds-checks
m_sel_solid_body (it defaults to -1, and run_verb bypasses the menu grey-out that used to hide
that); sketch_set_value validates its value at the boundary because apply_dimension records a
driving constraint even for values it refused to apply; and run_verb refuses btn:/fly: verbs
that do not apply to the selection while leaving key: verbs alone, so the socket offers exactly
what the GUI offers. Dispatch is deferred through CallAfter so no modal verb can wedge the
socket thread.

guards from 597557a6e4. Parity re-verified after every hunk: 17 files identical, 8 diverging by
their expected counts — DesignPanel.cpp still 32, DesignCanvas.cpp still 16, which is the proof
each hunk landed on the right side rather than being copied over a real divergence.
OFFSET OFFSETS THE CHAIN. Per-entity offsetting returned a closed rectangle as four parallel
segments that no longer touch, so entities_to_wires gave four OPEN wires and nothing could be
extruded. offset_entities now chains by shared endpoints and repairs each seam by mitering the
neighbours to their intersection. Second bug, invisible to any single-entity test: +d meant
"left of travel" for a line but "radius + d" for an arc regardless of sweep, so a slot outline
offset with its straights going one way and its caps the other. The convention is now written on
the declaration and pinned by a test.
tests/libslic3r/test_sketchprofile.cpp is new and asserts the LOOP rather than coordinates —
the property that decides whether a profile can be built, and the one the existing single-entity
[SketchEdit] cases cannot see. Its include is catch2/catch_all.hpp here: this fork ships Catch2
v3 while snaporca is on v2, which is why the test files are a tolerated divergence.
RIGHT-CLICK PICKS WHAT YOU POINTED AT, so a line's own verbs are offered instead of the
empty-selection vocabulary; sk_delete stops sharing btn:delete with the feature tree; and an
element's defining number (length / radius / diameter / angle / distance) can be typed, from the
menu or from V.
TWELVE MCP SKETCH VERBS. The socket had ~40 verbs and none touched a sketch, so the 2D layer
could only be exercised by driving a GUI with synthetic clicks. sketch_describe reports each
closed loop, the loops it encloses as voids, exact areas, and where a chain is still open;
sketch_validate/sketch_heal are FreeCAD's ValidateSketch — find vertices that overlap within a
tolerance but carry no coincidence, then weld them AND record the constraint, so a loop closed
by floating-point luck becomes one closed by construction. scripts/mcp-sketch-smoke.py is the
loop that asserts all of it.
Kernel suite on this fork: all tests passed, 2677 assertions in 230 test cases. The GUI target
links against the rebuilt deps image (the wxInspector blockage is gone) and the binary carries
the new verbs.

Both were mouse-only: Commit to Plate is a toolbar button bound to wxEVT_BUTTON,
the bed is a CheckBox, and neither had an accelerator. That put them out of
reach of anything driving the keyboard, and out of reach of a hand that had not
already left the model to find them.
Ctrl+Shift, because the Shift+letter space is full to the last letter and
because the char hook deliberately ignores every Ctrl-combo -- which is exactly
what leaves this layer free to claim. P is Plate and B is Bed; neither collides
with OrcaSlicer own Ctrl+Shift+S (Save as) or Ctrl+Shift+G (Print plate), and
nothing else in the tree binds either.
The lookup goes ahead of the guard that drops Ctrl-combos, and nothing already
bound changes meaning: a plain Shift+letter still resolves as before, because
the new layer only answers when Ctrl is held as well.
The bed toggle drives the checkbox rather than the viewport alone, so the
control and the view cannot disagree about what is shown, and it says which it
did in the status line.
Both verified on the running build: Ctrl+Shift+B toggles the grid and the
checkbox together, Ctrl+Shift+P commits to Prepare.

Reported on PR #15238: on macOS, drawing a corner rectangle and pressing Enter
on the first dimension opens the second field and then wedges the entire
application — no typing, no Escape, dead menu bar, no tab switching, and the
field stays composited over the desktop after minimising. That last detail is
what identifies it: an already-drawn window keeps being composited by the
WindowServer once the process stops answering. The main thread is stuck.
4c8c93b512 is the only commit that ever changed the second-queued-field path.
It stopped unmapping the value field between two queued dimensions, and its
whole justification is mutter: focus-stealing prevention refuses keyboard focus
to a window that was just re-mapped, which left the second field visible but
dead on GNOME (snaporca-p8uw). It was applied with no platform guard, so macOS
re-activates an already-visible borderless NSWindow at NSModalPanelWindowLevel
from inside wxOSX's pending-event drain — which on macOS runs from a
CFRunLoopObserver at kCFRunLoopBeforeTimers (evtloop_cf.cpp) over an unbounded
`while (!m_handlersWithPendingEvents.IsEmpty())` (appbase.cpp).
One constexpr now carries that choice, and both halves of the contract read it,
because the failure mode of this fix is the two halves drifting apart: open()'s
reuse-if-shown and do_commit()'s deferred hide are one decision, not two.
Not a macOS guess I could not check: the non-GTK branch was exercised on the
Linux rig by forcing the constant to false and rebuilding. A corner rectangle
drew, its first field committed at 60 mm, the SECOND field opened, committed at
40 mm, and the sketch ended at 60.0 x 40.0 mm with the field closed and no
freeze — so the map-afresh path is functionally complete, not merely different.
On GTK the constant is true and every generated instruction is unchanged.
What is still unproven is the exact line where macOS wedges; the reporter has
been asked for a `sample` of the hung process. This fixes the cause the evidence
points at without waiting for that, and cannot regress the GTK behaviour.

src/slic3r/GUI/CAD/ the tab — DesignPanel, DesignCanvas, DesignSketchTool,
SketchInlineEditor, McpControl, generated DesignOffer
Pure relocation: no line of logic changes. Two include rewrites follow from it —
files that moved re-spell their own neighbours against src/ (already on the
include path), and files that did not move pick up the new folder. docs and
docs/ux/mockups/gen_offer_table.py follow the same paths.
Verified: libslic3r, libslic3r_gui and libslic3r_tests all build, CAD suite green
at 2518 assertions in 194 test cases, and the sibling fork builds identically —
17 shared sources still byte-identical, 8 diverging by their expected counts.
Review request on PR #15238: "Move the SLVS to deps if the source code remains
unmodified. If any changes were made to the source code, move it to deps_src."
It is unmodified — all 20 files under src/libslic3r/slvs were byte-identical to
JacobStoren/SolveSpaceLib@4d87045, the extraction of solvespace.com's libslvs.
So deps/ it is, fetched by hash like every other dependency.
Only the CMakeLists is ours: upstream's builds a demo executable and installs
nothing, so deps/SLVS/CMakeLists.txt.in replaces it via PATCH_COMMAND — the same
shape deps/OpenCSG already uses. The public header keeps its spelling, so
SketchSolver.cpp still says `#include <slvs.h>` and needs no edit.
The CI deps cache is keyed on hashFiles('deps/**'), so it rebuilds itself.
Verified: dep_SLVS builds and installs, libslic3r links against SLVS::slvs, and
the CAD suite is unchanged at 2518 assertions in 194 test cases.
Selecting the web Device tab loaded the printer's web UI from the selected discovered machine
when the preset carried no host. That arm was lost merging main into this branch — two of the
three Plater.cpp hunks from #15134 survived, this one did not — leaving the tab blank, since
PrinterWebView starts on an empty URL and nothing else navigates it.
In printer-agents mode the legacy web page was appended under Notebook::PAGE_MONITOR, which
resolves to the same "monitor" id as the native Device tab. FindPageByName returns the first
match, so PluginPages::relayout() — which saves the selection by name and restores it after
rebuilding the tab strip — moved the user off the web tab onto the native one. The tab also
disagreed with its own label, being created as "Device (legacy)" and renamed to "Device (Web)"
on the next show_device() call.
The last unbuilt element of snaporca-wgsc. Two connectors a mate binds are one
object with a gap still in it; drawn as two separate frames they read as
unrelated, and "which two of these five frames are the mate?" had no answer on
screen at all.
Dashed, grey, drawn IN WORLD along the segment joining the origins -- so it
foreshortens with the model and its length is the gap the mate has left to
close. A Fastened mate therefore draws nothing, which is correct: the gap is
zero. Screen-constant dash pitch (6 px dash, 4 px gap) like every other gizmo
here, with the pitch opening up beyond 400 dashes so a mate across a large
assembly cannot emit thousands of segments. Depth test off: the line's job is
to say "these two belong together", and it has to say it even when a part sits
between the camera and one end.
Fed from BOTH sources of polarity truth, the same two the role colours already
use: every committed Mate feature (connectors named by feature index), and the
live pick of an open Mate card (named by combo ordinal). Only resolved frames
are eligible, so an unresolved end draws no line rather than a line to the
origin of the world.
RIG-VERIFIED on :10 with the fresh binary (/OrcaSlicer/build/src/Release,
2026-08-17 12:43): two imported bodies, a face-and-direction connector on each,
Planar mate offset 40. Sampling the segment between the two origins gives a
regular dash/gap alternation of 13:10 sample units -- the 6:4 px pitch -- in the
stroke grey (107,117,133), over both solids. The grey end keeps its open collar
head and the blue end its filled one, so polarity and pair now read together.
Refs snaporca-wgsc
Tommaso's decision (snaporca-x0kd): face orientation is hardwired perception -- a toddler reads
a face's roll and verse with no instruction -- so the connector is a face by default and the
conventional disc + roll quadrant stays, selectable, for users who expect it.
Preferences > Control > Camera > "Draw mate connectors as a face", default ON, key
design_connector_face_glyph. Read every frame rather than latched, so toggling takes effect on
the next repaint -- a look you cannot A/B without restarting will not get compared. Verified on
the rig: unchecking it switches the viewport to the disc live, no restart.
WHY A RELIEF AND NOT A DRAWING. A flat face in the connector's plane foreshortens by
sin(elevation) and collapses at a grazing view exactly like the quadrant it replaces -- measured,
the quadrant falls 89 -> 20 -> 3 -> 0 lit pixels from 47 degrees to edge-on. The relief does not:
its silhouette carries the information. So the glyph is a small shaded solid, painter-sorted,
lambert-shaded against a light fixed in CAMERA space so orbiting does not swing the shading.
THE MUZZLE, AND THE MISTAKE THAT NEARLY LOST IT. It is the only feature standing along +Z, so it
says which way the connector points and it is all that survives edge-on. Two errors on the way:
1. I built its footprint from height*tan(draft) and got a needle. The real base OVERHANGS the
crest at both ends (0.062 nose, 0.034 tail) and that overhang is what makes it a wedge. Base
now lifted straight off the mesh.
2. Worse, I chased fidelity. Scaled honestly the ridge is 11.3 mm on an 83.3 mm face -- 13.6 %
of the width -- and at 22-48 px that is a scratch. Tommaso looked at it and could not find
the muzzle at all, which is the only test that counts. A glyph is a symbol, not a scale
model, so it now gets two deliberate exaggerations, and COLOUR does most of the work:
muzzle share of lit pixels at 90/16/6 deg -- body tone 14.8/11.3/17.5 %, accent gold
18.3/19.2/23.9 %, accent gold at 1.8x width 23.5/25.2/31.2 %.
The accent is the same gold the disc spends on its roll quadrant, so it stays this tab's "here
is the direction that matters" colour. Polarity is still on the Z arrow's head; nothing collides.
A connector whose ROLL COULD NOT BE DERIVED keeps the disc treatment whatever the preference says.
A face asserts a definite orientation, and asserting one for a roll that was never derived is the
same confident lie that got billboarding rejected.
Geometry is emitted from the part by docs/design/mate-connectors/emit_glyph_table.py, not
hand-drawn, so glyph and printed connector cannot drift: 12-vertex outline, two eyes, chin bar,
cheek dot, and the snout wedge. Crest 29.0 mm / 6.58 mm drop / 13.1 deg against the review's
28.3 / 6.61 / 13.1 on the B-rep.
Also fixes extract_outline.py, which walked w.Edges: OCC returns them in storage order, not ring
order, ignoring per-edge orientation, so the outline was scrambled -- 45 points and perimeter
6.380 where a clean ring gives 31 and 3.335. Every measurement in the design notes was re-run.
The correction reversed one earlier finding: handedness does NOT read on its own (5.4/8.0/9.1 %
different from its mirror, not the 32-35 % the scrambled ring produced), so the cheek dot is
required rather than merely nice.
RIG-VERIFIED on Xvfb :12 against a 60x40x10 box with a face+edge connector: the face renders with
both eyes, ears, chin bar, cheek dot and a gold muzzle standing proud; the Z arrow degenerates to
its ring when viewed down the axis; and the preference switches to the disc live.

snaporca-wm4s. Thickening the 4-walled open box (60x60 in plan, 40 tall, no caps)
by 5 produced volume 29648.15 where the geometry requires (60^2-50^2)*40 = 44000
— about 67% of it. The corner material at the four vertical edges was simply
absent.
CAUSE. MakeThickSolidBySimple offsets each face along its own normal and sews;
it never extends neighbours to meet, so wherever two faces join at an angle the
corner is empty. A flat sheet has no such join and was always exact (18000.000),
which is why the defect looked like a measurement artefact.
WHY THE TWO EARLIER ATTEMPTS COULD NOT HAVE WORKED. Both switched to ByJoin —
plain, then with Intersection/GeomAbs_Intersection — and both returned a shell,
not a solid, so the body lost its volume entirely and both were reverted. That is
not a parameter problem: in OCCT, BRepOffset_MakeOffset::MakeThickSolid builds a
solid only inside `if (!myFaces.IsEmpty())` (BRepOffset_MakeOffset.cxx:1115).
Handed an open sheet with no closing faces, it stops after the offset shell and
returns it, reporting IsDone() with a non-null shape containing no TopAbs_SOLID.
ByJoin hollows a CLOSED solid by removing faces; an open sheet is outside its
contract.
FIX. Close the sheet, then use the call that mitres: cap the free rims
(ShapeAnalysis_FreeBounds -> MakeFace), sew shell+caps into a closed shell, make
a solid, and hollow it inward passing the caps as the faces to remove — the caps
come back off and leave the wall. Two details, each found by measurement rather
than reasoning:
* A shell sewn from an extruded sheet carries no guarantee of outward
orientation, and MakeSolid does not fix it. Inside-out, the inward offset goes
OUTWARD: measured bbox 70x70x40 and volume 339141.59, larger than its own
bounding box because the result overlaps itself. A negative GProp mass is
exactly that inversion, so it is the test; Reverse() on it.
* A SINGLE face has no neighbour to mitre and must keep the BySimple path. It
does have a free boundary, so "has free wires" is the wrong question — capping
a lone face with its own rim sews a zero-thickness shell and measures 6000
against 18000.
Also: IsDone() is not a success test here, since both failed attempts had it
true. The code now explores for TopAbs_SOLID and refuses a shell.
Tests: new case asserts 44000 with the wall's bbox at 60x60x40 (catching the
inverted-orientation shape, which has the right volume nowhere near the right
place), plus the flat-sheet control at 18000 that must not regress. Full kernel
suite green: 2502 assertions in 187 test cases.

Follow-up to the previous commit, found by driving the app: clicking Login /
Register on a fresh install pops "You are currently in Stealth Mode. To log
into the Cloud, you need to disable Stealth Mode first." — to a user who has
never touched the toggle, whose config says stealth_mode: false.
It is the same pre-wizard latch one step earlier. handle_web_request() gates the
login commands on get_stealth_mode(), which reports stealth while
firstguide/finish is unset, so the app blocks sign-in because the wizard is
unfinished — backwards, since signing in is how a user leaves that state.
Worse, the escape it offers does not work. "Quit Stealth Mode" writes
stealth_mode = false, which was ALREADY false, and never touches the latch: the
config is byte-identical afterwards and get_stealth_mode() still returns true.
The user clicks the button, believes stealth is off, signs in, and finds every
cloud feature still dead. That is the state the reporter of #15239 described.
So the login guard now reads the user's OWN setting via the new
get_stealth_mode_setting(), not the pre-wizard default. A user who deliberately
enabled Stealth mode still gets the dialog and the working Quit button; a user
who merely closed the wizard goes straight to the login page.
Measured on Xvfb with a fresh datadir (firstguide absent, stealth_mode false):
before, clicking Login produced a "Stealth Mode" window; after, it opens the
"Login" window directly. And with the previous commit's latch release, a real
Orca Cloud sign-in on that same unfinished-wizard profile now runs the whole
post-login flow — the sync prompt fires (sync_user_preset lands in the config),
the per-user preset folder is created, and Sync Presets syncs with no refusal.

Reported on #15239: after signing in to Orca Cloud on a fresh install, no sync
prompt appears and File > Sync Presets is greyed out with nothing to explain why.
CAUSE. AppConfig::get_stealth_mode() returns true whenever `firstguide/finish` is
unset, and that flag is written in exactly one place — GuideFrame::SaveProfile(),
i.e. only when the setup wizard is COMPLETED. Closing the wizard is what people do
today to reach the login (the wizard never offers it, which is #15239 itself), so a
new user ends up permanently in a stealth mode they never chose. Every cloud gate
keyed on get_stealth_mode() then switches off silently, including:
* GUI_App::on_user_login_handle(), which returns EARLY on stealth — so the whole
post-login flow is skipped: preset migration, plugin fetch, user-preset load and
show_sync_dialog(). That is the missing sync prompt.
* the Sync Presets item in both the top menu and the File menu, whose enable
lambda was `is_user_login() && !get_stealth_mode()`. That is the greyed item.
The result is indistinguishable from real Stealth mode, and nothing in the UI says
so, because the one place that DOES explain it — the "Quit Stealth Mode" dialog in
handle_web_request() — only covers the homepage login commands.
FIX, two parts.
1. The pre-wizard value is a DEFAULT for "the user has not been asked yet", not a
setting, so it must not survive the user answering. Signing in to a cloud account
is that answer. AppConfig now carries a session-only `m_cloud_logged_in` mirrored
from the network agent (on login, on logout, and at agent start so a restored
session counts), and get_stealth_mode() consults it before falling back to the
pre-wizard default. An explicit Stealth mode setting is untouched and still wins:
a user who turned it on deliberately stays offline whether or not they sign in.
2. Sync Presets no longer greys itself out. Both refusal paths already had a message
to show — "You must be logged in…" and now one for Stealth mode naming the
Preferences toggle — and the enable lambda was making both unreachable. A disabled
item that cannot say why is the reason this took a bug report to find.

snaporca-x1k7 filed three Transform defects. Two were real and are fixed here;
the third does not reproduce and is withdrawn with its measurement.
(1) The feature tree had no ITEM_ACTIVATED binding at all, so double-clicking any
row only highlighted it. Double-click is the documented edit gesture elsewhere
(a committed sketch opens that way on the canvas), which made every feature look
dead until the user found the Edit button in the section header. Bound to
on_edit_feature(), so the gesture now works for every feature type, not just
Transform.
(3) The Transform card's typed fields called refresh_preview(), but preview_fields
returns {} for Transform and the solid-preview path has no ghost to build for a
feature that moves an existing body — so typing a distance changed nothing on
screen until Confirm. The fields now drive the same channel the gizmo drag already
uses: the body's display transform. In EDIT mode the committed transform is
already baked into the kernel geometry, so the preview undoes it first; without
that term, re-opening a committed Z=20 and typing 40 would show the body at 60.
(2) NOT REPRODUCED. Dragging a rotation ring does fill the field: a tangential
drag on the red ring gave Rotate axis = X, Angle = 27.44 deg, plus the translation
that rotating about the card's pivot implies (Y 17.60, Z -62.11). The original
reading came from a drag that never grabbed the 7 px ring; this run took its
candidate points from the rendered ring pixels themselves and 6 of 6 answered.
Rig-measured (docker snaporca-gui, Xvfb :10, llvmpipe), vertical screen shift of
the body by image correlation:
commit Translate Z 0 -> 20 : +140 px
double-click the Transform row : +0 px, and the card re-opens showing 20.00
step the re-opened card 20 -> 40 : +142 px (not +280 -> the undo term is right)
Cancel : +0 px vs the committed frame, residual 0.46
Add mode: stepping Z moves the body immediately (viewport diff bbox
200,143-1181,999); Cancel puts it back with only the status strip differing.
