e6dc105134 Point clouds: insert PLY, XYZ and PTS scans as a modelling reference (#5151) (#5381)
* Point clouds: insert PLY, XYZ and PTS scans as a modelling reference (#5151)

A point cloud is kept in the design as a reference, drawn as depth-tested
dots and never a body.

- io: a PLY reader (ASCII, binary little/big endian; x, y, z of any numeric
  type, optional colours, other elements skipped; counts checked against the
  file) and XYZ/PTS text, thinned evenly past max_points. PLY meshes with
  faces can also come in through file.insert_mesh.
- doc: Document.point_clouds (shared f32 points relative to an f64 origin,
  colours, units, rigid placement, size and colour), stored as a binary
  container part; format change in pending/point-clouds.rs.
- engine: pointcloud.insert / edit / delete / list; doc.open opens a cloud as
  a new design; selection.delete takes point_clouds; view bounds include them.
- gpu: an instanced point-sprite pipeline (16 bytes a point).
- ui: Browser Point Clouds folder with eyes, menu and an Edit Point Cloud
  card; drop, Open, Insert and file dialogs take .ply/.xyz/.pts; a CPU
  viewport fallback; messages in en, en-GB, ja, zh, de and ko.

* Point clouds: colour by the file, one colour or height, from the UI (#5151)

The Edit Point Cloud card gets Color By (File Colors, Single Color,
Height). Height is a blue-to-red ramp over design Z, between the cloud's
own two heights or, by default, a range worked out from the points (all
but the lowest and highest 2 %, from an even sample). pointcloud.insert
and pointcloud.edit take color_by and height_range; pointcloud.list
reports them. The colour of each point is worked out in one place
(PointCloud::shade) for the GPU and CPU viewports.

Also: the card's dropdowns compare the picked index (a dropdown's
response doesn't report the pick, so File Units did not change either).

* Point clouds: integrate format registration and viewport caches (#5151)

* Point clouds: satisfy current UI audits and document comparisons (#5151)

Route model RGB data through the theme conversion boundary, provide a compact ribbon label, and include point clouds in the new document comparison. Gate the Unix-only CLI-link helper and test so Windows all-target checks remain buildable after the rebase.

* Point clouds: isolate translations for current main (#5151)

Move the existing 74 messages unchanged into one pending locale file and attribute it through a pending row, following the current repository workflow. Repository checks, 50 tooling tests, final workspace Clippy, wasm and generated-catalog equality checks passed after the rebase.

866029aaa2 Engine: one sketch store for the sketch commands (W38.0, #5425) (#6336)
* Engine: one sketch store for the sketch commands (W38.0, #5425, no behaviour change)

The sketch commands found and kept the sketch they work on in about forty places, each its own
way. They now go through one module, cmd::sketch_store, so a drawing session (W38a/b) can put
sheet and view sketches behind the same calls without the commands changing again.

- target: the command's `sketch` param or the sketch being edited (target_sketch, moved).
- active: the sketch being edited, if any. The thirteen commands that need one keep their own
  refusal text; unifying the three texts is a separate, visible change.
- read and write: the only calls from the sketch commands to Document::sketch and sketch_mut.
- update: change a sketch on a copy of the document and keep both, the edit the text and link
  commands made by hand (sketch.text, sketch.edit_text, the projection, intersection and
  include links, sketch.fit_curves_to_section, sketch.break_link). As before, those paths
  neither solve the sketch nor run its checks.
- checked: the checks an edited sketch passes (the periodic splines), shared by edit_solved and
  sketch.offset.break.

edit and edit_solved stay in sketch.rs and load and keep their sketch through read and write.
Imported text, snap points and the face projections keep their own shape (a text that can't be
linked is skipped, snap points copy the document only when one is needed) through read and
write. The reads and writes that are about the design's own sketches stay as they are, each on
a line marked `// design-only:` (Redefine Sketch Plane, a joint's curve, a motion trace's wire,
and the session's live drag, parameter edits and `created` diff).

A source scan, each_sketch_command_goes_through_the_store, fails when a command reads or writes
a sketch, or asks for the active one, anywhere but the store or a marked design-only line in the
files that work on the design's sketches. Every existing sketch test is unchanged.

* Engine: the sketch store's scan also catches the active sketch taken as a value (#5425, review of #6336)

The scan only caught `active_sketch.ok_or`, so main's `let Some(id) = s.active_sketch else …`
could have come back unseen (0xlillith's review). It now also flags the value-read forms:
`) = s.active_sketch` (let-else and if let), `=> s.active_sketch` (a match arm),
`s.active_sketch.and_then(` and `s.active_sketch.map(`. State checks (`is_some`, `is_none`,
`== Some(`), assignments and snapshot copies stay allowed.

The wider scan found five commands that hand-rolled the store's `target` rule (a `sketch` param or
the sketch being edited). They now call `sketch_store::target`: sketch.inspect, sketch.glyphs,
sketch.export_dxf, inspect.curvature_comb and inspect.minimum_radius (their `curves` form).
Their refusals become target's:
- no `sketch` and none being edited: "no sketch is being edited" (was "no such sketch (and none
  is active)", or "no such sketch" for sketch.glyphs);
- an unknown name or id: "no sketch `X`" (an unknown id used to reach "that sketch is not
  evaluated");
- a feature that is not a sketch: "`X` is not a sketch";
- a `sketch` that is neither an id nor a name (true, a list, an object): refused,
  where it used to fall back to the sketch being edited. A null `sketch` still means none given
  (the scenario harness sends one): target now reads it that way for every sketch command
  (target_reads_a_null_sketch_as_none_given).
No test, doc or schema text named the old wording; the params docs ("sketch?: id|name (default
active)") still hold.

The two remaining value reads, the default sketch for a feature (features.rs) and the sketch a
measurement prefers (measure_sel.rs), go through `sketch_store::active`, with no change.

* Engine: a number in `sketch` is an exact sketch id, never a name (#5425, review of #6336)

`sketch_store::target` turned a JSON number into text and looked it up with
`Document::find_feature`, which falls back to a name when no feature has that id. So
`{"sketch": 999999}` could pick a sketch named "999999" whose id is something else, and export
or inspect it. sketch.export_dxf, sketch.glyphs and the two curvature inspects read an exact id
before they moved onto the store; the other sketch commands (the old `target_sketch`) and
sketch.inspect read a number as text.

One rule now, for every command that takes `sketch`: a number is an exact id (`as_u64`, then
the feature with that id); text is an id written out or a name, as before. A number that isn't
a whole number of 0 or more (negative, fractional) is refused with "`sketch` must be an id or a
name"; an id no feature has gives "no sketch `N`", as before. Nothing in the tests, docs,
scenarios or examples names a sketch with digits, so nothing relied on the old fallback.

Test (sketch_store): a sketch named "999999" with another id. sketch.export_dxf, sketch.glyphs
(with another sketch being edited, for its enabled check), inspect.curvature_comb and
inspect.minimum_radius (with a real curve id) refuse `{"sketch": 999999}`, find the sketch as
`"999999"` and by its own id, and refuse -1 and 1.5.

* Engine: MidPoint finds its sketch through the store too (#5425, after #5011)

#5011 added a caller of the old `target_sketch` (MidPoint's `line_stays`, which swaps a point
picked after its line) after this branch's base. It now reads the sketch through
`sketch_store::target` and `sketch_store::read`, as the other sketch commands do, so a number
there is an exact id too.

* Engine: standard parts fix their sketch's entities through the store (#5425, after #6376)

#6376 (a standard part's sketches are fully defined) reads the sketch being drawn straight from
the document's features, after this branch's base. `fix_all` now takes it from
`sketch_store::active` and `sketch_store::read`, as the store's scan requires, with the same
result.

* Engine: Toggle Diameter and Delete on a profile find their sketch through the store (#5425)

Two sketch commands landed on main after the store: sketch.toggle_diameter (#7729) still
called the removed sketch::target_sketch, and Delete on a picked profile (#7107) read the
sketch straight from the document. Both now go through sketch_store (target and read), and
the store's source scan passes again.

semmelrindeandClaude Opus 5.5 683535a18f Evaluation: a pattern of another component's body follows its own component when that moves (#8467)
A pattern of bodies copies them about an axis in its component's frame,
so its copies of a root body depend on where that component is placed.
placement_digest never counted a pattern's bodies, so moving the
component kept the cached copies. Read each body through placed_body,
as Combine does.

semmelrindeandClaude Opus 5.5 2841210fb2 Sketch Dimension: choose horizontal or vertical from the two points' box (#7295) (#7355)
* claim: #7295

* Sketch Dimension: choose horizontal or vertical from the two points' box (#7295)

Two points or a slanted line got the aligned distance whenever the text
was between the perpendiculars through them, so straight above the middle
of nearly level points was aligned and horizontal needed a thin wedge.
Now the text position relative to the box the two span picks the type:
inside it or in its outer corners aligned, above or below horizontal,
beside it vertical. This is the rule midpoint pairs already used, so both
share auto_orientation().

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Sketch Dimension: aligned across the line, horizontal or vertical by the pull past an end

Review on #7355: the aligned length must stay the default, and the box
rule shrank its zone to a thin strip on a shallow line. Now `auto` is
the distance between the two points everywhere across from them
(between the perpendiculars through them, and a tenth of their distance
past), and only a clear pull past an end changes it: up or down from
that end gives the horizontal distance, sideways the vertical one. The
two meet on the diagonals through the end, so both zones stay wide on a
shallow or steep line. Midpoint pairs keep main's box rule.

froglemonade2andClaude Opus 5.5 f595f38e1c Define a named parameter inline from any value input (#4071) (#7341)
* claim: #4071

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Define a named parameter inline from any value input (#4071)

Any value input, typed or sent as a command's expression parameter, takes
`name = expression` (or `#name = expression`): the design gets the user
parameter `name` with that expression, and the input stores `name`, in the
command's one undo step.

- doc: the lexer skips a definition's `name =`, so until the design stores
  it the text evaluates as its expression and commands read and check it
  like any value. `Document::define_inline` then turns every stored
  definition (feature inputs and placements, dimension parameters, sketch
  pattern and text values, joint and coupling values, sheet metal and
  plastic rules, canvas planes) into a user parameter, the unit following
  how the input reads a bare number. A taken, reserved or empty name, two
  different values for one name, and a definition in a parameter's own
  expression or a configuration cell are refused; all or nothing.
- engine: `Session::execute` runs it after any command whose parameters
  hold definition-shaped text; the reply has `defined` (the first name,
  as `sketch.dimension` already gives) and `definitions`. A refusal fails
  the command, which leaves the design as it was.
- `parameters.change` with `new = expression` renames the parameter it
  changes (a dimension's or feature input's own, references following)
  and sets it; when the value is just `new`, it sets `new`. `changes`
  refuses definitions. `expr.evaluate` reports `defines`.
- UI: lengths keep the name when the design unit is applied; sketch text
  sends a definition as typed and previews only its value; the box corner
  and offset Distance 2 use the value; fields whose command keeps no
  expression (sketch scale, move, chamfer) refuse a definition with the
  way to name it. The dimension editor says which parameter it named.

02ac56d12f Feature windows choose Join, New Body or Cut from what the material touches (#6901) (#6903)
* claim: #6901

* Feature windows choose Join, New Body or Cut from what the material touches (#6901)

Extrude, Revolve, Loft, Sweep, Coil and the Box, Cylinder, Sphere and Torus choose
their operation by running the Join on a copy of the design off the window thread
and counting the pieces: Join when the material makes one body with what it
touches, New Body when it would be a separate piece, Cut when it lies inside a
body (Revolve and the four primitives; Extrude keeps its own Cut). The choice
changes only when a check is in, a pick in the Operation row (the shown option
included) stops it for good, and OK waits for a running check. Hidden bodies take
no part: with some hidden, the shown ones become the feature's targets.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Operation row: a pick in Extrude stops its own choice at once; ja/zh strings, gallery entry

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Operation check: contact test first, mesh volumes for Cut, OK takes the evaluated Join

Material touching no body is a New Body without running the Join (the contact
test costs 0-240 ms where the Join costs seconds on a large body). Inside is told
from display-mesh volumes instead of exact ones (8 s on a 400-hole plate). The
check evaluates the Join through Session::ahead, and OK of the same commands
takes it (Session::prime) rather than computing it again.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Preference: Choose the operation automatically (on by default)

Preferences > Design gets "Choose the operation automatically" (auto_operation,
on by default). Off, feature windows don't choose Join, New Body or Cut from
what their material touches: each keeps the operation it opens with (Extrude
its own Join or Cut), no check runs and OK doesn't wait for one, as before

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Arabic, Hebrew, Vietnamese and Turkish strings for the operation choice and its preference

Arabic, Hebrew and Vietnamese are complete catalogs now, and Turkish has a full
catalog, so this change's three strings get them too.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Operation check: a closed window's check stops; the icon audit doesn't choose

A window's operation check kept running after the window closed, a Join on
the design for nothing, and the test harness waited for it after every step:
the icon audit, which opens every window, took ~30 min instead of ~1. The
check now runs under a Progress, and closing the window (or one that doesn't
choose) abandons it: its evaluation stops at the next feature and nothing
waits for it. The icon audit turns auto_operation off, as it only looks at
icons (75 s again).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Box placement test: the window keeps its New Body

The test #6248 added places a box that overlaps Base and expects a second body;
with #6901 the window would join or cut it. The test is about where the box
goes, so it turns auto_operation off.

* claim: #6645

* Sketch: Center Point Arc follows the cursor clockwise or counter-clockwise (#6645)

The centre-point arc always ran counter-clockwise from its start; a
clockwise arc needed a typed negative sweep. The tool now tracks the
signed turn the cursor makes round the centre after the start is placed,
and its sign sets the direction of the preview, the live Sweep box and
the created arc.

sketch.arc.center_point takes `clockwise` with a clicked end: the arc is
stored counter-clockwise from the end and reversed, as a negative sweep
is, so the start keeps its radius and `<id>.start`.

6fffd745fd Insert Part: the Length list opens on the default length, with no "Default" item (#8020) (#8022)
* claim: #8020

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* Insert Part: the Length list opens on the default length (#8020)

The list carried an item called "Default" above the standard lengths. It
never said which length it stood for, and one of the lengths below it
always was that length, so the list offered the same length twice under
two names. Change Part Size has always listed concrete lengths.

The item is gone and the list opens on the length the part would be given
anyway. The default cannot be worked out in the dialog, because it is not
one rule: a cap screw or bolt takes the first standard length at or above
2.5 d, a set screw the first at or above d, a dowel pin the first at or
above 4 d. parts.library now reports default_length beside each size's
table values, taken from the shape the engine would build, and the dialog
selects it; the test checks that report against what an insert without a
length is actually built to, for every size of every family.

Leaving the length alone behaves as "Default" did: a new size resolves
the list again, so M6 to M12 moves the selection from 20 to 30. A length
chosen by hand stays until the size changes.

Claude-Session: https://claude.ai/code/session_019FAWPuFoh9qxn2uS2j53QZ

* DXF import: an elliptical arc comes in as exact conic arcs (#8155)

A partial ELLIPSE (how Fusion, and SolidCraft's own DXF export, write an
elliptical arc) was read as a degree-3 spline fitted through 16 samples,
which strays from the ellipse between them: 0.84 mm on a 300-degree arc
of a 200 x 40 mm ellipse. It is now read as exact rational-quadratic
conic pieces of at most a quarter turn each, which the sketch keeps as
conics. A conic arc written by SolidCraft's DXF export now reads back as
the same conic.

The arc's sweep is taken with rem_euclid instead of a loop that added a
turn at a time, which ran for billions of turns on a start angle of 1e11.

sketch.drawing_bounds and the width/height sizing of sketch.insert_dxf
measure a conic by points along it, not by its apex, which can lie
outside the curve.

Homero Thompson f103468dba Params: a list parameter refuses a wrong type instead of losing entries (#6651) (#6683)
* claim: #6651

* test(#6651): a list parameter of the wrong type is refused

A list parameter such as a cut's `targets` or an export's `bodies` loses entries without an error: a value of the wrong type reads as an empty list, which most commands take to mean "every body". The regression test drives the engine the way a user does: two bodies, a box cut that crosses both and is meant for one of them, and a `targets` of the wrong type. The command must refuse it and leave the design as it was.

* fix(#6651): a list parameter refuses a wrong type instead of losing entries

A list parameter of the wrong type was read as an empty list, and an empty
list means "every body" to most commands: a cut meant for one body cut every
body it touched and the command reported success.

A wrong type is now an error that names the parameter, the offending entry
index and the value it got. A list longer than 10000 entries is an error
instead of being cut short. `null` stays absent, as the schema contract says,
and a plain string is still a list of one. The 80 call sites now propagate the
error instead of losing entries; the commands that take feature keys, which
may be named or numbered, read them with their own reader.

Christian HammacherandClaude Opus 5.5 aae2c5e417 Assemblies: edit a linked component in place, with the assembly around it (#7672) (#7819)
* Links: update linked designs that changed while the assembly's tab was away

A design coming back to its tab compares the modification time and size of its linked
design files with what they were when it went to the background, and runs Update Links
on the worker thread for those that changed: saved in another tab, another window or by
a checkout. Preference update_changed_links (Design, Linked designs) turns it off.

* Docs: the assembly guide says linked designs update when their tab returns

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Links: Vietnamese strings, now that vi is a complete catalog

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Links: remember what each design last read, so an update that fails is tried again

A design's linked files are now recorded as the design last read them: when Update Links reads a
link without an error, or when the link is first seen. Coming back to the tab reads again what
differs, one link per run, so a file that cannot be read holds up no other and is tried again
the next time, and a part changed while the assembly was shown is taken up on its next return.
Closing several tabs together reads nothing on the way, and the web build, which keeps no file
times, looks at nothing.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Links: no read during a save-changes prompt, records for adopted designs and missing files

A tab shown to answer "save changes?" reads no link before its save, and Cancel there or on a
batch lets the tab left in front read what it skipped. A design opened in place of the blank one
records its links at once, a link whose file is missing is recorded as missing so it is read when
the file comes back, and a read queued for a design that is no longer shown by the time it starts
is dropped. More changed links than can wait at once are read on the next return.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Assemblies: edit a linked component in place, with the assembly around it

Activating a linked component opens the design it comes from in a tab of its own, with the
rest of the assembly drawn faded around it where the component sits, so the part's own history,
browser and commands are at hand. Finish Editing in the browser saves the part, goes back to the
assembly and closes the part's tab when the edit opened it; coming back to the assembly updates
the changed link (or Finish Editing runs Update Links when that is turned off). Update Links in
the part also reads the assembly's links again, off the window thread, and redraws the assembly
around the part; a result for an assembly changed meanwhile is dropped with a message.

The part is an ordinary tab, so saving, autosave, recovery, closing and quitting treat it as any
other design. The model scene's ghost triangles are now drawn (only the preview's were).
Preference edit_linked_in_place turns it off. Builds on the update of changed links when an
assembly's tab returns.

* Edit in place: a double-click opens it, Activate only activates

A double-click on a linked component edits it in place, in the browser as on a face in the
view (around the placement clicked), and the component's menu gets Edit in Place. Activate and
the browser's radio button make it the active component as they always did, so a linked
component can still be activated without opening its design.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Double-click on a component's face: edit a linked one in place, activate any other

A double-click on a face in the view activates the component the body belongs to, at that
placement, as a double-click on its row does; a linked one is edited in place. Bodies of the
design itself or of the active component are left alone, and so is a double-click with a
modifier. One preference, double_click_components, covers both gestures.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Edit in place: fixes from review

An edit whose part never opens is forgotten instead of starting on a later open of the same
file, and the web build starts the edit after its synchronous open. Finish Editing goes on only
for a save into the linked file and in the part's own tab, waits for a "changed on disk"
answer, and says so when the part was saved elsewhere. Showing the assembly no longer drops a
refresh, which now records the links it read so coming back reads nothing twice. The faded
assembly is worked out once per picture, a bad mesh index skips its whole triangle, and the
last two status texts come from the catalogs.

* Edit in place: Finish Editing on the MODEL tab and the mouse's back button

Finish Editing is a command now, component.finish_edit, with its schemas: the app window
answers it, anywhere else nothing changes, as with view.fit. While a linked design is edited in
place the MODEL tab ends with a FINISH EDITING panel, pinned at the right as FINISH SKETCH is,
with a new left-arrow icon; the browser keeps only the line naming the assembly. The mouse's
back button, or a keyboard's Back key, finishes too unless a dialog, tool or sketch is open.
The assembly guide describes editing in place.

* Edit in place: fixes from the second review

Saving the assembly waits while it reads its links for the part
Finish Editing waits for dialogs, tools, sketches and prompts open in the part, also when run as a command
The assembly reads the edited part explicitly when it does not check its links on its own
The FINISH EDITING panel cannot be customized
A tab opened by an edit stays that edit's to close when the part is entered again
The mouse's back button finishes editing; the keyboard's only while no text field has focus

component.finish_edit run as a command opens nothing and answers with an error when it cannot finish; engine.batch and engine.script refuse it

What changes in the assembly while it reads its links without changing its document stays: picks, activation, components dragged but not captured

A new or opened design in the part's tab ends the edit
Finish Editing keeps the part's tab open while its agent chat runs

Finish Edit waits while the part's agent is in the middle of its turn, instead of keeping the tab of any chat open
A part saved while its assembly refreshes is read again when the edit finishes: the refresh records the files as it found them
A double-click on a linked component while something is open in the assembly says so instead of activating it
Commands are recognised in any spelling the engine takes, so engine.batch and engine.script cannot slip Finish Edit through
Update Links run as a command refreshes the assembly from the control channel only, not for the app's own reads
Moves of components the refresh removed are not carried over, and a refusal is one message
The command description and the guide say that the command does not save the part

* Edit in place: a command to start it, and fixes from the full review

Added component.edit_in_place {component, path?}: the double-click and Edit in Place in the menu run it, and as a command it asks nothing, so a network location not allowed yet or a design open elsewhere makes it fail instead
Finish Edit asked by the part's own agent finishes once that agent's turn ends; the button still waits for the turn
The parameters and design properties panels, with text typed and not applied yet, hold up entering and finishing an edit
A refresh is not taken up under an undo, a queued command or a feature still being computed in the assembly
Refusals say what holds them up (a refresh, a file being read or written) instead of nothing
The browser strip names the assembly that is refreshing, not any assembly
The schema description says the command does not save the part
Korean strings for every new message

* Edit in place: fixes from the second full review

The MCP batch tool refuses component.edit_in_place and component.finish_edit as steps instead of sending them one by one
Edit in Place asked while the assembly's agent is in its turn opens the part once the turn ends; a double-click then is refused rather than stopping the agent
Both commands answer queued: true when they wait for the agent's turn, and stopping the agent forgets what it queued
An undo, a queued command or a delete check running in the design holds up entering and finishing an edit
A refresh redraws every edit of the assembly, the parts in other tabs too
In an assembly never saved, a double-click activates the linked component as before
The control and MCP docs list the new batch and script refusals, and the commands list every way they fail

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Edit in place: fixes from the third full review

The MCP batch tool refuses the two commands however a step names them, an execute step too
A queued Edit in Place is checked fully when asked for, a second one is refused, and both queued requests wait for what runs in the design instead of being dropped
Disconnecting the agent forgets what it queued, as stopping it does

CamWightandClaude Opus 5.5 14acdc2a6d Render: one sRGB transfer function (#7161) (#7162)
* Render: one sRGB transfer function, geom::srgb, for the hand-written copies (#7161)

Twelve places wrote the sRGB encode or decode formula out by hand (doc's glass
recipe, engine's render library, glTF import, the PNG film, photographic and
presentation output, the ray tracer's image, the stage, the surface decoder,
texture normalisation and the theme's contrast check). They now call
solidcraft_geom::srgb: encode/decode on 0..1 values, encode8/decode8 for 8-bit
codes. render::surface::srgb8_to_linear stays as a re-export, so its callers
are unchanged.

Same results: the module's tests compare it bit for bit with the formula as the
callers wrote it, over all 256 codes and a dense sweep of linear values plus
the knees, out-of-range values, infinities and NaN, for each way the callers
clamped (after encoding, before it, or not at all), and decoded values either
side of the decode knee, where no 8-bit code falls.

One change: glTF import encoded in f32. Over every f32 in 0..1, 218 of
1,065,353,217 values sit on a rounding tie that f32 got wrong and now give the
neighbouring code (f64 gives the nearer one).

Left as they are: render/job/image.rs (replaced by exact tables in its own
change), the tests and the starter-pack validator that keep their own copy as
an independent reference, and the WGSL shaders (they can't call Rust).

Fixes #7161

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Tests: the sRGB codes of five callers that had no test of their output (#7161)

The glass swatch, a library surface applied as a plain appearance, glTF's
fallback for a colour channel that isn't a number, a stage panel and an empty
pixel in presentation output each get an assertion with their sRGB codes worked
out by hand. A planted wrong conversion at each is now caught by that test.

* View angles: an optional readout under the orientation gizmo and a command to set them (#6032)

View > View angles (also Preferences > Graphics, or view.angle_readout) shows the
view's pitch, yaw and roll in degrees and Ortho/Persp under the axis view or cube,
updated live; off by default. Clicking the readout opens a small card to type
exact angles, which runs view.apply.

The angles are the camera's own (Camera::view_angles / with_view_angles), about
the up axis: yaw is the heading of the line of sight (Front 0, Left 90, Right -90,
Back 180), pitch the eye's elevation (Top 90, Bottom -90), and a positive roll
turns the model clockwise. view.apply documents this convention and now refuses a
pitch past +/-pi/2.

Homero Thompson 31d6873f7d OBJ export: the body colours travel with the file (#4451) (#6693)
* claim: #4451

* fix(#4451): the body colours travel with the OBJ file

An OBJ export left the colours of the design behind: the mesh file named no
material, so every body arrived in the reader's default grey. The export now
writes a material library (.mtl) next to the mesh file, with a material per
body, and the mesh file names that library with mtllib and picks the material
of each body with usemtl. Every path is checked before anything is written,
the library goes first and the mesh file last, so a mesh file never names a
library that is not there. Only the colour of the body travels: the colours of
single faces and the transparency of a body stay out, as a face colour needs
material groups inside one object. The export that writes one file stays
material-free, so it never names a library it does not write.

A mirror's or pattern's copy of a face carries its seed's construction certificate, and on a
combined body that certificate finds the seed's face. Capturing an attachment never checked
that the certificate finds the picked face, so a sketch on the mirrored half sat on the
original. The capture now falls back to the face's exact history name when the certificate
names another face, as docs/face-attachments.md describes.

nothing asked for, reordering or moving an earlier feature re-evaluated
them all and the first name lookup (a fillet at the end) recursed once per
feature, overflowing the 1 MB window-thread stack on Windows. Name every
16th earlier version oldest first so no lookup recurses through more than
16 of them; the names are the same.

timeline.redefine builds the edited feature and the features after it in its trial session;

changed. Report the trial's rebuild, plus anything the session still had to compute itself, as
timeline.edit reports the same change; `restored` keeps counting only genuine reuse of earlier

Tests: redefining_reports_the_features_it_rebuilt fails before the change with

redefining_computes_the_later_features_once still guards the single computation (the reply

9bcb2ffe68 Drawings: first landing from the drawings branch (#8249)
* Drawing sheets: sizes, the ISO 5457 border and its marks (#3875) (#5108)

* Drawing sheets: sizes and the ISO 5457 border (#3875)

A sheet is a paper size and an orientation: ISO A0 to A5, Letter, Legal,
ANSI A to F, architectural A to E1, or a custom size (finite, above 0 and
at most 5,000 mm a side), landscape by default and either way for every
size.

A border profile is the rule for its border, and layout() works it out
for a sheet: the frame inside the margins, and the reference fields with
their labels. The ISO profile has a 20 mm filing margin on the left and
10 mm elsewhere, a 0.7 mm frame, fields of 50 mm out from the centre
lines with the corner fields taking what's left, rows lettered from the
top without I and O (AA, AB and on past Z), columns numbered from the
left, and an A4 sheet labelled on its top and right only. A profile can
divide the frame equally instead, or have no grid.

The records sit in geom, next to the section records, so saving,
rendering and export can all use them. Nothing is saved or drawn yet:
there is no command and no format change. Margins that leave no drawing
space, values that aren't finite, fields outside 1 to 1000 mm, more than
200 equal fields and unknown JSON fields are refused.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Drawing sheets: ISO 5457's centring and trimming marks (#3875)

A drawing border profile now also holds the grid reference border and the
centring and trimming marks, either of which can be left out. The ISO
profile follows ISO 5457:1999 (read in its identical adoption,
IS 10711:2001):
- the grid reference border 5 mm outside the drawing border on every
  side, with the field labels between the two;
- four centring marks on the sheet's centre lines, from the grid
  reference border to 10 mm inside the drawing border;
- at each corner a trimming mark of two overlapping 10 x 5 mm
  rectangles, in the margin outside the grid reference border.

The labelled sides are now a rule worked out for each sheet: ISO 5457's
(the top and right of A4, all four sides of the others) or fixed sides.
So one profile labels every size correctly. validate() checks what
doesn't depend on the sheet, for when a profile is read; layout() calls
it, then checks the rest against the sheet.

Refused:
- a grid reference border that isn't finite, is negative or is wider
  than a margin;
- a centring mark that isn't above 0, would reach past the sheet's
  centre lines, or is on a drawing border those lines miss;
- a trimming mark that isn't above 0, is wider than it is long, is
  wider than the margin left outside the grid reference border, or is
  longer than half the sheet's shorter side.

The grid rule's JSON is now externally tagged ("none",
{"from_centre": {"field_mm": 50}}), as the sheet size is, so an unknown
field is refused in every form; the internally tagged "none" ignored
one. Nothing is saved yet, so the shape change costs nothing.

The names follow the glossary, and ISO 5457's "drawing sheets": the
module is drawing_sheet (was sheet, which means sheet metal elsewhere
here), DrawingBorderProfile and SheetLayout (were BorderProfile and
BorderLayout), sheet_border and drawing_border (were paper and frame),
and Sheet::size_mm (was paper_mm). The first part of S1 is still a draft,
so the renames are made here rather than in a commit of their own.

The extra centring marks ISO 5457 asks for on sheets larger than A0
aren't here yet. Still nothing is saved or drawn.

* Drawing sheets: a lighter built-in border, the filing margin a choice (#3875)

Cameron's decisions after seeing the sheet in the app, 2026-10-23:
- No trimming marks in the built-in profile: the filled corner blocks
  take a lot of ink. trimming_mark_mm stays, so a profile can still ask
  for them.
- Centring marks stop at the drawing border: from the grid reference
  border to the drawing border, never into the drawing area (on A4 they
  crossed the tables). centring_mark_mm keeps its meaning, how far a
  mark reaches inside the drawing border, and now takes 0, the built-in
  value, as grid_border_mm already takes 0 for "on the drawing border".
  A mark of no length (a reach of 0 with no grid reference border) is
  refused.
- Margins of 10 mm all round. ISO 5457's 20 mm filing margin on the
  left, for drawings that get bound, is a named choice: filing_margin,
  off when not given. On, it stands in for margins.left_mm, which is
  kept, and still checked, for when it's off again. The 20 mm is
  FILING_MARGIN_MM, and validate() and layout() both take the margins
  from one helper, laid_out_margins().

A3 landscape is now 400 x 277 at (10, 10), with eight 50 mm columns.
With the filing margin it is 390 x 277 at (20, 10) again, the same as a
20 mm left margin set by hand. A profile with all three choices on
(ISO 5457's full border) lays out exactly as the built-in profile did
before, and the tests keep the old hand values for it.

with the object that drew it (an opaque id) and its kind, with one validation pass over a bounded
record count. Seg2's checks and the coordinate rule move into profile.rs so section and paper share
them, and drawing_sheet takes its side and line limits from paper, so each limit is written once.

* Drawing sheets: centring marks across the whole margin (#3875) (#5554)

The built-in sheet's centring marks now run from the trimmed sheet's edge to the drawing border.
From the grid reference border, as before, a mark was the same length as a grid field mark, and on
A3 it sat on one (the sheet's centre falls on a field edge), so it no longer read as a mark once the
grid reference border's outline is left out (Cameron, after the prototype on #3875).

- DrawingBorderProfile.centring_mark_start: sheet_edge (the built-in's, and when not given) or
  grid_border (ISO 5457's figure 5); ISO's full border in the tests asks for grid_border.
- A mark still needs a length: one that stops on the drawing border needs room outside it on the

* Drawing sheets: no centring or trimming mark longer than the largest sheet's side (#3875) (#6410)

A border profile capped every length at 5000 mm (the largest sheet's side) but two: a
centring mark's reach inside the drawing border and a trimming mark's length. A file could
give either a huge whole number, such as 18446744073709551615. The read's number check passes
whole numbers, so the profile took it as 1.8e19 mm, and saving wrote it as a decimal the next
read refused: a drawing that saved but didn't open again. K2's fuzz test of drawing files
(#3890) found it.

Both now take the cap the margins have, `MAX_SIDE_MM`, in `validate`, so the file is refused
when it's read. Layout's own checks against the sheet are unchanged, so a 5000 mm mark still
validates and is refused only on a sheet too small for it.

Tests: the hostile-profile test refuses 5000.000001 mm and 1.8e19 mm for each mark, and takes
5000 mm on its own; 4 planted faults (each cap removed or made one short) are all caught.

* Bill of materials types: phantom, reference, purchased and inseparable (#3874) (#5107)

* Bill of materials types: phantom, reference, purchased and inseparable (#3874)

A component's bill of materials type is a part property (`bom_type` in its metadata, set with
component.metadata.set and read by component.metadata, as part_number is), so older releases
keep it and no format change is needed. It isn't a design property: the Design Properties
dialog doesn't list it and document.metadata.set refuses it. A word this build doesn't know
reads as normal and is kept.

assembly.bom counts by type: a phantom has no row and what it holds counts where it is placed,
in the same rows as the same parts there; a reference counts nowhere, and nothing inside it
does; purchased and inseparable components are one row, and in parts only an inseparable
component's purchased parts are listed too. Rows of one part number but different types are
different rows. Rows and children carry bom_type. With no types set the rows are as before.

* Glossary: bill of materials and bill of materials type (#3874)

The bill of materials types are a new idea, so the glossary gets their
term, with the five types, and "normal" gets its fourth meaning in the
table of words with more than one meaning.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Bill of materials types: a plain line for each (#3874)

The guide's table and the glossary entry say what each type is for in
plain words: something you make, something just to group, something to
use as a reference, something you buy, something made as one piece.
The names stay the five standard ones.

* Bill of materials: kits fold together only when their contents' types match (#3874)

With group_children, two kits with one part number share a row when what they hold reads the
same. That reading (kit_key) compared each child by part number and count, but not by its bill
of materials type, though rows themselves are told apart by type. So a kit holding a made bolt
and a kit holding a bought one, both KIT, folded into one KIT x2 row listing the first kit's
bolt twice: the other type was lost, and which one depended on creation order. 0xlillith found
it in review of #5107.

kit_key now includes each child's type. Equal part number, type and contents still fold.

Test: two KIT kits each holding a BOLT fold into one row of two; once one bolt is purchased they
are two rows, each listing its own bolt. Planted fault (the type left out of the key): caught.

* Drawing files: a drawing saved as a container or as plain JSON, never read as a design (#3890) (#7098)

* File format families: drawings share the design format's versioning (#3890)

The format code works for a family of files: its own tag, its own numbers and
its own folder of change files, with one reading of a file's format, one
refusal of a file a newer build saved and one upgrade for every family. Designs
(solidcraft/N) are one family and keep everything they had: FORMAT and FORMATS
are as they were, and pending_names, format_string, version_of and read mean
what they did. Drawings (solidcraft-drawing/N) are the other, with format 1 as
their first record and each later change one file in
crates/doc/src/drawing/format/pending/, as design changes are. Nothing saved
changes.

A design tag never reads as a drawing's or the other way round, and a file that
names no format is a design from before format strings, never a drawing. Every
refusal names its family; a design's read word for word as before. A design
listing a pending change this build doesn't have is now refused as a newer
build's before its content is checked, as a newer number already was, so a
newer build's fields never read as damage. The list reader is
take_names(v, key, noun), the shape #4811 uses for its own list.

For the maintainer, the release step changes: scripts/fold-format-pending.sh
now folds every family that crates/doc/build.rs lists (FAMILIES), each into
its own next number: designs into crates/doc/src/format/v<N>/ as before,
drawings into crates/doc/src/drawing/format/v<N>/ from 2. With nothing pending
in a family it says so and moves nothing. Its test folds a drawing change into
v2 beside the design changes. docs/releasing.md, CONTRIBUTING.md and AGENTS.md say so.

build.rs lists each family's changes from its own folder, each folder's
versions contiguous from its own base.

* Drawing record: format 1 of the drawing family (#3890)

A drawing is now a record of its own (crates/doc/src/drawing.rs): its name,
the designs it draws (sources: an id and the design file's path, relative to
the drawing's folder as a linked design's is), its properties under the design
metadata's rules, its units (each design's own, or one length unit of the
expression unit table), its content language (a BCP 47 tag) and its sheets.
A sheet holds its paper, a copy of its drawing border's profile, the
resolution its pictures are rendered at (300 dpi unless it says, 25 to 2400),
the component it documents and whether it is left out of the sheet count or
of printing. This is format 1 of the drawing family; each later kind of
record adds one file in crates/doc/src/drawing/format/pending/.

The rules: one id counter for every object, raised above the largest id when
a file is read and never rewound; every reference is an id that must resolve,
or the file is damaged and refused, never patched; 1 to 1,000 sheets, at most
64 sources, names of 1 to 256 bytes, paths of 1 to 4,096 bytes without NUL.
The same drawing always saves as the same bytes.

Drawing::from_json reads at most 16 MiB of text, then runs the family's format
check, the number check, the upgrade, the typed record (unknown fields refused
everywhere) and Drawing::validate. The number check is now one function every
family calls, Family::check_numbers, told which field holds other tools' data;
a design's refusals read as before.

Nothing saves or opens a drawing yet: the container is the next step.

* Drawing ids: random and collision-free from format 1 (#3890)

A drawing's objects now take random ids, the form jyviko chose on #3890 from
#1017: no counter, so objects added on two branches never share an id and
never edit one line. The allocator is one module for drawings now and designs
later (#626 Phase 3), crates/doc/src/ids.rs: an IdSource gives nonzero u64s by
splitmix64 from a seed, each checked against the ids in use and drawn again
when it is one, or when it is 0. A run never draws a number twice, so at most
one draw per id in use comes before a free one, and a seeded run over a file
the same seed made still gets a new id. IdSource::seeded gives the same ids
for tests and replays; IdSource::from_entropy seeds a session from the
standard library's hash keys, the time and a count, with no new dependency.

In a file an id is 13 characters of Crockford base32, lowercase
(0000000000001 to fzzzzzzzzzzzz): ids::encode writes it and ids::decode reads
only that spelling, case-sensitive, so an id has one form to search for.
Anything else, 0 included, makes the drawing damaged. The drawing loses
next_id (a file that holds one is refused), and Drawing::new and allocate_id
take the IdSource. Messages name ids as the file writes them. The component a
sheet documents stays its design's own number until designs move over.

* Drawing record: a drawing too large to reopen isn't saved (#3890)

from_json reads at most MAX_DRAWING_BYTES (16 MiB), but to_json had no limit. Other tools'
properties are kept as they came, and indenting them can grow a drawing read in at about 4 MB
past 16 MiB (two million zeros in one array), so the next read refused what the save had just
written. 0xlillith found it in review of #3891.

to_json now returns a Result and refuses JSON longer than a read takes ("drawing too large to
save (at most 16 MiB)"), so every drawing saved opens again. Nothing writes drawing files yet, so
the error reaches the future file writer before it publishes anything.

Test: that case is refused, and a smaller compact drawing saves and reopens unchanged.

* Drawing files: a drawing saved as a container or as plain JSON, never read as a design (#3890)

K3 of the drawing storage plan (W11.2): the file a drawing is saved in. Nothing writes one from a
command yet; opening and saving come with K5.

- A drawing container is a design container holding `drawing.json` (Deflate, as `document.json`)
  in place of `document.json`, and `container.json` says so:
  {"content": "drawing", "format": "solidcraft-container/1"}. A design's `container.json` is as it
  was, with no `content`. The plain JSON form is the drawing's own text. Both give the same bytes
  every save, so a drawing can live in version control as text.
- `io::file_kind` tells a design from a drawing by `container.json` or by the JSON's format. The
  design reader refuses a drawing ("this file is a SolidCraft drawing, not a design: open it as a
  drawing") and the drawing reader a design; plain JSON only asks when it isn't a design, so
  reading a design costs nothing more. A container's content this build doesn't know, or a drawing
  container that also holds a design's `document.json`, is refused.
- `read_drawing` (bytes, either form), `read_drawing_file` (one seekable handle, the design
  reader's checks) and `write_drawing_container`; `DRAWING_EXT` (`scdwg`) and
  `is_drawing_path` beside the design's.
- The container writer's set-up and finish, the file opening and the container sniffing move into
  one function each, which designs and drawings both use. The container's own checks (budgets,
  entries, the ZIP directory) are the design container's, word for word.

Tests: a drawing round-trips through both forms byte for byte, and the container holds exactly
`container.json` and `drawing.json`; `file_kind` on both forms of both kinds; each reader refuses
the other's file; unknown content, a stray `document.json`, a missing drawing, an unknown
container version and a damaged drawing refused; both forms from disk, and a directory refused;
mutation fuzz of both forms (an error or a drawing, never a panic).

* Paper scene: SVG of a sheet, its lines, arcs, cubics and fills (#4890 A3a) (#7032)

The first export of a paper scene, as SVG first (jyviko and 0xlillith on #4890), from the research
in the plan's §16. A3b adds ellipses, hyperbolas and Béziers above degree 3, which this refuses as
"not supported yet".

- `geom::paper::Prepared`: writers read a scene through `Scene::prepare`, which checks it first, so
  none reads one unchecked. Clipping goes there too, once (A8).
- `geom::paper::arc_pieces`: an arc's ends in pieces of at most a quarter turn, the last its own end.
  A half turn drawn from its ends is ill-conditioned: rounded to the nanometre (six decimals of a millimetre) its
  centre moves up to 1e-2 mm, where a quarter turn's stays under 1e-6 mm.
- `io::paper::paper_svg`: one user unit a millimetre, the size in mm on the root; y flipped by
  writing the height less y, so the file's numbers are page coordinates and an anticlockwise arc
  has sweep flag 0; lines `L`, arcs `A` (never large-arc), cubics `C`, parabolas `Q`; fills
  black and even-odd; one path per item; groups as `data-object` and `data-kind` (object ids can't
  be XML ids). No background, so cutters see only the marks.
- Numbers are whole nanometres (six decimals of a millimetre): no exponent, no "-0", the same bytes every time. They are the
  writer's own state too, so a joint is written once and a closed path ends exactly on its first
  point. Numbers are written straight onto the document, with no text made per number. A width
  under half a nanometre is written as one, and a piece too short for the grid is merged into the
  next, both counted in the report; a path's last piece has no next, so it is kept however short
  (unless it has no length). Output over 64 MiB is refused.

Tests: the A3 drawing border's whole document; quarter, 270°, clockwise and whole-turn arcs, and a
circle of two halves giving the same four quarters; the quarter-turn boundary both sides; cubics and
parabolas, and the conics refused; the number format; a closed path whose start and end round
apart; a sliver merged; an open path's short last line and arc kept, and one of no length dropped; read back through our own SVG reader (lines exactly, the arc as an arc);
the scene's JSON mutated into the writer (never a panic).

* Drawing W17a: view definitions as data (#4816) (#4817)

* claim: #4816

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Drawing views as data: named views, scales and the map onto paper (#4816, W17a P1)

What a drawing view is, before anything draws it (geom::drawing_view):
- NamedView: the six principal views and the isometric views from the four upper corners, each
  an exact basis (a Plane whose normal points back at the viewer), never taken from a camera,
  whose pitch clamp would tilt a top view, with no -0 to write out; `iso` reads as the
  front-right one.
- basis_looking: any other view from its direction, an up and an origin (paper x = direction x up,
  paper y = x x direction), refusing a zero direction, an up along it, or an origin that isn't
  finite or within 1e12 mm. W07's
  {direction, up, origin} view reads through it.
- Scale: paper : model as two positive numbers, read and written as "1:2", from 1:100000 to
  1000:1; Scale::fit picks the largest ISO 5455 preset (50:1 to 1:10000) at which a view fits a
  space (W07's "fits the page" default), compared as size x paper <= room x model so an exact
  fit at a reduction isn't lost to rounding.
- ViewFrame: a view's basis, scale and place on paper, the point of its plane at `centre`
  landing at `position_mm`. Its paper map moves the view's curves and their accuracy onto
  paper (paper error = scale x model error); `boundary` maps a box of its plane onto paper from
  its four corners.

In geom, where Seg2 lives:
- Similarity2 and Seg2::similar (new): scale, turn and shift a segment exactly, an arc staying an
  arc. Similarity2::new refuses a scale that isn't above 0 and works the turn out once, not per
  point;
- Seg2::map_controls: a segment's control points mapped by any function. It was doc's
  sheet::map_controls; its four callers in doc use the method now, unchanged.

CurveAccuracy::scaled gives a curve's accuracy at another scale.

Tests: each named view's basis and viewer side, and the same bases from a direction and up; a 50 mm cube in every principal view at 1:1 and
1:2, and in isometric (edges 50 x sqrt(2/3), outline 50 x sqrt(2)); the view's centre on its
position (W07's 100 x 20 front view on A3 at 2:1); scales read, written and refused; the fitted
scale, an exact fit at 1:5 and ISO's smallest; no -0 in any named view's axes; an origin refused by
its own message; hostile bases, centres and positions; every segment kind moved by a similarity,
and the similarities refused; scaled accuracy.

* Drawing views: the bottom view pinned, square near parallel, bounded scales and boxes (#4816)

From DevonHope's review of #4817:
- The tests pin all six principal views exactly. The direction-and-up test uses literal ups,
  so a bottom view turned half round now fails it.
- basis_looking squares x to the direction before normalising. Near the 1e-9 threshold the
  normal was up to 8.8e-9 rad off; now it is about 1e-16.
- Scale::fit fits nothing for a size or room that is negative or not finite. A size of 0 still
  sets no limit that way.
- Each side of a scale is 1e-6 to 1e6, so a scale writes at most 49 characters.
- ViewFrame::boundary returns a Result. It refuses a box that is inside out or not finite on
  paper, instead of dropping a corner.
- paper_map, boundary and seg_to_paper say which coordinates they take.

* Drawing W18 S2: title blocks as data (#3875) (#3877)

* Title blocks: what a cell shows and where its text goes (#3875)

geom::cell holds a title-block cell's content: parts of text and fields
(component, drawing, sheet, revision or prompt, by key, with an optional
unit and decimals kept as written for the resolver to check), at most 64
parts and 4096 bytes of text, with no control character but a line break.
Beside it are a resolved value (live, overridden and drifted, or missing,
with "-" for each part that couldn't be read and why), an override with
the value it replaced, and the projection a drawing's views use (first or
third angle), which the title block's symbol will read.

A fit warns and never cuts: a count of characters, not bytes, with its own
count for text in Chinese, Japanese, Korean or Yi characters.

The cell text rule places a label and a value: the label's baseline 1 mm
plus its cap height below the cell's top, the value box under it inset by
1 mm, one line centred in the box, and wrapped or several lines down from
its top at the font's pitch, with a warning when the last falls below the
box. Wrapping by width, width warnings and glyphs a font lacks need the
text measured, so they wait for the paper scene's text.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Title blocks: definitions and their place on a sheet (#3875)

geom::title_block holds a title block's definition: its size (1 to 1000
mm a side), its outline and cell line widths, and up to 64 cells. Each cell
has a snake-case name of its own, a rectangle measured from the block's
lower-right corner, an optional one-line label with its cap height, and a
value: text from cell content, with its cap height, alignment and fit, or
the projection symbol, which reads the drawing's projection and is never
fixed in the block.

validate() checks a definition on its own, as when one is read: cells
inside the block and not overlapping (touching is fine), label and value
cap heights that fit, and the content's own limits. layout() puts the
block on the drawing border's lower-right corner of a sheet, refusing one
that doesn't fit, and gives each cell's rectangle, its label's place and
its value box by the cell text rule. On A3 landscape a 180 x 54 mm block
runs from (230, 10) to (410, 64); it fits A5 landscape and every larger
sheet, but not A5 upright.

* Cell text: a value box lies within the paper's coordinates (#3875)

place_lines took any finite, ordered value box, but centring one far out (min x 1e308, max x
1.1e308) overflows: the anchor came back infinite, with no warning. 0xlillith found it in review
of #3877.

The paper scene already bounds every coordinate it holds by MAX_COORDINATE_MM (twenty times
the longest sheet side). That limit is now public, and place_lines keeps its box inside it, so
its anchor is always finite: one rule for what a paper coordinate may be.

Tests: the hostile-box test refuses both overflow cases from the review and a box just past the
limit on each side, and places lines in a box the size of the whole paper limit. The fuzz test's
numbers now include values past the limit (1.1e5, ±1e308).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Title blocks: padding from the lines' inner edges, one label rule, nothing unread (#3875)

A cell's text is padded from the inner edge of its lines: each side of a cell moves in by half
the line drawn on it (the outline's on the block's edges, a cell line's inside), so a wide
outline never covers the text. Before, the padding ran from the line's centre.

The label's one-line rule lives with the cell text rules (`cell::check_label`), where parts
lists will find it. The cell types nothing read yet (`Override`, `Resolved`, `State`,
`Problem`, `Reason` and `MISSING`) wait for the resolver that will read them.

The tests check the exact thresholds inside the lines (a label that leaves no room, a value
that just fits), pick each of the lines, alignment and wrapping on their own so every
combination comes up, and lay fuzzed blocks out on every standard sheet, either way, with and
without the filing margin.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Title blocks: the drawing border's line, descenders, room where the block sits (#3875)

From DevonHope's review of #3877:
- Each cell's lines are clamped to the inner edge of the drawing border's line. That line runs
  along the block's right and bottom edges, and along any other edge it reaches, as when the
  block fills the border. Aabb2::intersection, the 2D twin of Aabb3's, does the clamping.
- layout checks each cell's room again where the block sits (place_cells, which validate runs
  at the origin), so rounding at the real corner can't turn a cell inside out.
- The cell text rule counts descenders, at 3/10 of the cap height (ISO 3098's lettering B).
  They may reach into the padding under a value box, never past it to a line. place_lines
  warns Height when they would, and validate asks it whether one line fits.
- The module doc no longer links to a private function.

* Drawing W06a: exact orthographic hidden lines for the analytic subset (#2455) (#2457)

* Drawing W06a: exact orthographic hidden lines for the analytic subset (#2455)

crates/geom/src/hlr (L0): prepare once per body, then hidden_lines for a
scene of placed bodies. Edges and face silhouettes are projected from their
exact curves, split where projections cross, and each piece is classified by
rays toward the viewer against the trimmed faces: visible, hidden or
explicitly uncertain, never guessed. Planes, cylinders, cones, spheres and
tori are supported whether stored as analytic records, revolutions or spline
patches; freeform faces are reported and make what they could hide
uncertain. Screen geometry is Seg2 with the W01a accuracy vocabulary: exact
lines and conic arcs where the projection is exact, bounded chords
otherwise. docs/drawing-hlr.md holds the contract and its limits.

* geom/hlr: handle the brep records main gained in #3093

Main's exact model storage (#3093) added Curve::SurfaceIntersection,
Surface::PlaneThrough and Surface::PlacedRevolution, and the HLR matches on
the records no longer compiled. A plane through three points is a plane: it
is trimmed and intersected as one, and a box stored that way draws the same
bits as one with axis-stored planes. The procedural intersection curve and
the placed revolution (whose affine placement may scale it unevenly) are
refused by prepare as not supported yet, until the kernel adapter handles
them. The records' positions move with the body's centre like the others.

* geom/hlr: pad plane faces' boxes, so a plane record off by rounding still hides

Plane faces took the box of their boundary chords unpadded, flat along the
normal. When the plane record and its edges disagree by rounding (a unit cube's
top plane one ulp above its edges, a 100 mm cube's 1e-11), the ray toward the
viewer reached the plane just outside that box, the slab test culled the hit,
and the back edges came out Visible with no doubt. Every face's box is now
padded by 1e-6 of its size, as curved faces' boxes already were. Reported by
DevonHope on #2457.

* geom/hlr: limits from review: trim samples, scene extent, crossing pairs, surface groups

From DevonHope's review of #2457:
- Options::trim_samples must be 1 to MAX_TRIM_SAMPLES (4096).
- Placed bodies must stay within MAX_COORDINATE (1e12 mm, as section and brep
  bound stored numbers). Placements 1e200 apart made the scene's size infinite
  and every tolerance taken from it with it, so everything came out Visible.
- The crossing search counts its candidate pairs before it starts and meets
  each pair only in the first grid cell the two segments share, instead of
  keeping a set of the pairs met, which could outgrow wasm's 4 GB before the
  500 million pair budget tripped. The same pairs in the same order.
- prepare groups faces on one quadric or torus by comparing each face with
  the faces of its kind whose size agrees to the tolerance (sorted), not with
  every face; at most 50 million comparisons. prepare_cancellable polls a
  cancel callback between edges, faces and comparisons.

* geom/hlr: boundary chords on a grid, and no fine pass over coincident curved chords

The cost items of DevonHope's review of #2457:
- Every ray hit asked how far it lies from its face's boundary by scanning all
  of the face's chords (4096 per circle; a plate's face with 256 holes has
  about a million). The chords are now bucketed on a uniform grid over the
  boundary's box, cells at least as long as the longest chord, and the test
  looks only at the cells around the point. It finds exactly the chords the
  scan finds.
- Chords of two curved curves that lie on each other end to end (aligned holes
  seen along their axes) were cut into 16 by 16 pieces and intersected, to
  find crossings that are only noise within the curves' tolerance. They are
  now skipped; visibility changes where a coincident run starts or ends, and
  chords that only partly overlap still find those.
- Fixtures: a plate with holes, coaxial cylinders seen along their axis, and
  300 placements.

* geom/hlr: pad boxes by the body's coordinates too; coincident chords only to rounding

Review of the previous commits found two holes:
- The padding grew with the face's size, but rounding grows with where the body
  was modelled: a 0.001 mm cube 1e7 mm out, its top plane one step (1.9e-9 mm)
  above its edges, still had its hit culled. The pad now adds 1e-12 of the
  body's offset.
- Two chords were taken for coincident when their ends lay within each other's
  sag, which in a coarse scene can hide real crossings: an arc can bulge across
  a line 1 mm off its chord twice. Only chords that coincide to rounding are
  skipped now; identical projections, the costly case, still are.

* geom/hlr: coincident curves meeting at shared sample points do not cross

Timing the review's scenes showed that skipping coincident chords was not
enough: chords of two coincident curves also touch end to end at every sample
point they share, and each touch was a crossing to refine and split at. 64
coaxial cylinders seen along their axis gave 8.3 million crossings (19 s), 64
cylinders one behind another along the line of sight 4.2 million (214 s;
before these commits the crossing budget refused it). A touch at a shared
sample point is now dropped when the two curves also coincide, to rounding, on
both sides of it. Where a coincident run starts or ends one side differs, and
the touch is kept.

* geom/hlr: the own-face margin allows for rounding where a body was modelled

The far 0.001 mm cube of the previous commit showed a second effect of records
rounded at large coordinates: its top plane, one ulp (1.9e-9 mm) above its
edges, hid the top edges themselves, because a ray leaving an edge met its own
face 3.2e-9 mm along, past the own-face margin of 1e-6 of the face (1.4e-9).
The margin now also covers 1e-14 of the body's offset (about 45 ulps of its
coordinates), which only matters for parts far smaller than their distance
from the origin.

* geom/hlr: no parity test for a hit on the boundary, where it is uncertain anyway

* docs/drawing-hlr: the fixtures of the review's second round

ermanyop-stack a5f472c23e Prevent angular drags from collapsing construction geometry (#8148) (#8160)
* Reject newly collapsed angular reference lines (#8148)

Reject angular solutions that collapse a reference relative to its input length. Cover constrained drags and already-short references. Engine replay and full CI validation remain in progress.

* Cover live and non-live angular drags (#8148)

Adds a replay of #8148 for live and non-live drags. The integration test compiles locally, but the Windows GNU test executable exits with STATUS_ACCESS_VIOLATION before running tests, including with --list/--help. Kept in the draft PR pending validation on a working native runner.

Dahak BuildsandDahak Builds 64ff25f380 Fix sketch drag breaking midpoint-constrained line solver (#7635) (#7810)
* claim: #7635

* Keep the drag cursor on the manifold of an ill-conditioned sketch (#7635)

A construction line collapsed to zero length makes its angle row's entries
on that line ~1e7 while the same row's entries on the measured line are ~1.
Dragging an endpoint of the midpoint-pinned line then failed two ways: the
null-space rank analysis, which scaled rows only, hid the small (physically
meaningful) entries below its pivot tolerance and let the measured line
rotate freely; and the cursor's refinement, which demanded a TOL-tight
correction the ill-conditioned system cannot deliver, gave up entirely and
let the drag leave an unsolvable step placed - breaking the perpendicular
and angle constraints.

Equilibrate the null-space Jacobian on both sides (columns by their largest
entry, then rows) so one row's entries share a scale, and let the cursor
keep working from a pose the solver itself calls solved (residual below
ACCEPT) when refinement stalls above TOL, accepting corrected trials at the
same tolerance the final validation uses.

* claim: #7855

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_019FAWPuFoh9qxn2uS2j53QZ

* Motion interference: a check cut short by its work budget is not clear (#7855)

motion.interference stops when its work budget runs out (truncated) but
answered clear: collisions.is_empty(), so a check that reached only the first
steps read as a pass: a gear pair checked for 14 of 61 samples was "clear".
clear is now true only when every sample was checked and none collide.

The budget is an argument of interference_within, so a test can cut a check
short: B slides up to touching A, a full check is clear, and the least work
that checks a first step stops after 1 of 16 samples with clear: false (it
was clear: true before). The guide and the mechanisms skill say the same.

The issue's second request, a budget_s on motion.interference, is not here.

Refs #7855.

* Motion interference: budget_s gives a check the time it needs (#7855)

The work budget is fixed, so a gear pair drawn in detail was cut short
after a few samples, or refused before its first one. motion.interference
now takes budget_s (seconds, above 0, at most 86400, as inspect.interference
allows): the check then runs until that time instead of the work budget,
looked at before each sample, and echoes budget_s in its answer. Without
budget_s nothing changes. The refusal before a first step now names the
budget that ran out and suggests budget_s.

Tests: given a time, the smallest work budget (which checks no step) no
longer stops the check, through motion.interference too; budget_s 0, -1,
1e9 and "soon" are refused.

Fixes #7855.

* Canvas and Decal: send the picked face, so a large design takes the image (#5592)

A click with Canvas or Decal sent only the point, so the engine searched every face of every
body for it and gave up on a large design ("face capture work limit exceeded"). Send the
picked body, face index and path as Create Sketch does; canvas.decal takes that face pick too.

* Canvas and Decal test: drop the check that a point alone gives up

On upstream main a sketch on a face by its point alone no longer gives up on this design, so
the test keeps only what the picked face has to do: both images land on it.

A connector's boss extruded up to an enclosure's face (each in its own component) merged the
enclosure into the connector, and features referencing the swallowed body failed after it.
The body it runs to now joins only when it is in the feature's own component, or when the
feature names it as a target.

* Sketch: Delete on a picked profile deletes the curves around it (#7107)

While a sketch is being edited, a profile picked by clicking inside a
shape stands for the curves of its outer loop, so Delete removes the
shape instead of failing with "a profile goes with its sketch". Holes
inside it are shapes of their own and stay. Outside the sketch a
profile still goes only with its sketch.

* Sketch: deleting a dimension in a rolled-back history no longer rebuilds the features after the marker (#7253)

The check before a delete evaluated the whole history twice when the
timeline was rolled back. Removing a sketch constraint changes the later
features' cache keys, so on a long history Delete on a dimension took
minutes. When the design differs only in sketch constraints (and model
parameters nothing uses any more) and each changed sketch solves to the
same geometry, profiles and ends, the features after the marker see the
same inputs: compare the live models only. Anything else still gets the
full check, so the report is unchanged.

bherbruckandClaude Opus 5.5 7a6c884418 Change the app id to io.tangencylabs.solidcraft, with aliases for existing installs (#7681)
The app id moves from ai.storyteller.solidcraft to io.tangencylabs.solidcraft: macOS bundle id
(the CLI signs as io.tangencylabs.solidcraft.cli), Linux desktop/metainfo/MIME file names, icon
name, Wayland app_id / X11 class, Flatpak, Snap common-id, nfpm/FreeBSD/Nix/AppImage staging,
the web app's icon paths and the docs.

Existing installs keep working: the Flatpak repository marks both old ids
(ai.storyteller.solidcraft and ai.storyteller.solvecraft) end-of-life with a rebase straight to
the new id, re-marking the solvecraft ref that pointed at the 0.8 id; the manifest grants
read-only access to both old ~/.var/app folders and the first launch copies settings and
autosaves from the newest one; AppStream <replaces>/<provides> and X-Flatpak-RenamedFrom list
both; the AppImage removes menu entries it wrote under either old id. The data and settings
folders (solidcraft / SolidCraft) are unchanged. The MSI UpgradeCode and ProgIDs are unchanged.
