doc: world_state, world_state_reusing, state_in_frame_at, state_in_frame, face_point_state,
face_point_names and construction_state return Result. A body that could not be placed, a
frame that could not be inverted, a sketch plane or thread axis that did not survive the
placement, or a failed placing worker used to leave things where they were without a word;
now the call fails with what could not be placed. is_placement is the one test of an
occurrence's placement (finite, a rotation that does not mirror, a translation within
1e9 mm). Opening a design names every occurrence that fails it; add_occurrence refuses
one; a joint solution that would place an occurrence outside one is not applied and the
joints placing it report it.
engine: Session::world_state returns Result and keeps a failure in its cache as it keeps a
placed model. bounds, home_camera, open_sketch_plane, the scene builders, the world
previews, frames::to_local and auto_operation pass the error on; helpers answering "not
found" take the placed model from their caller. Commands setting a placement check it
(valid_position, exploded view, fastener at a point, STEP insert matrix).
ui: panels, picks and hovers read the session's placed model through
open_meshing::session_world; a model that cannot be placed shows no placed bodies, and the
viewport says why across its bottom. Pictures and the control channel report the error.
cli, mcp: snapshots, renders, benches and the oracle report the error; the kernel-case rig
records it as the case's failure. Tests read the new Results with unwrap.

* claim: #5853
* Batch: refuse a step that would fail at its turn before the first step runs (#5853)
engine.batch and the MCP batch tool checked only a batch's shape up
front. A misspelled command id in a late step was found at its turn,
after every earlier step had run, and then all of it was rolled back: a
160-step batch with a typo as its last step ran for a minute and
changed nothing.
solidcraft_engine::batch_preflight::check finds, before anything runs,
the first step the batch would certainly refuse at its turn: a step
without a command, an unknown command id (the error names the closest
ids, as at the step's turn) or, with strict parameter checking, a call
that breaks its command's typed contract. Anything that depends on the
design is left to the step's turn.
- engine.batch (control channel) checks against the app's registry and
its session's level; view.pick, which the app answers itself, passes.
- The MCP batch tool checks when the commands run in its own process
(headless, with --param-check from the backend). A running app may be
another version with other commands and checks the batch itself; its
reply's not_run is passed on.
- The refusal is the failing step's reply with completed 0, undone 0,
not_run listing every step and a note.
Tests that used an unknown command only to make a late step fail now
use a step that fails at its turn (a bad extrude distance), so they
still test rollback, timings and file.new as before.

* Every new command comes with input and output schemas
A test fails for a command without a contract or an output type, unless it is a planned!
placeholder or listed in schema/unconverted.txt, which holds the 400 commands that predate
the rule and only shrinks: the test also fails when a listed command has its schemas, when
the list names a command that doesn't exist, or when it isn't sorted.
`checked!` now takes only the command's id and checks the contract that id publishes
(`run_checked_as`), so the contract enforced is always the one described. Another test runs
every command that has a contract in strict with an unknown key, so a contract is never
published without `checked!`, under the command's own id, enforcing it.
A new book page, Command schemas, explains how to write a contract and a reply type, the
tests to add, the shared field types and how to add one, with a checklist; the failure
messages point to it. "Adding a command", CONTRIBUTING.md and AGENTS.md now include the
schemas, and the MCP tool description and docs/mcp.md no longer list the converted commands.

- The example primitive's `targets` default to every body in the feature's component, not the
bodies it meets; they're ignored when `participants` lists bodies.
- Check what each value does where the feature is evaluated, not only how the handler reads it.
- A reply test runs every form in Warn and checks for no `param_warnings` (Strict for a reply
that isn't an object).

* claim: #5822
* Batch: consecutive parameter edits can rebuild the design once (#5822)
An agent's batch of parameter edits, one parameter per step, evaluated the
design once per edit: an edit early in the timeline rebuilds nearly all of
it, and 21 such edits ran for minutes.
engine.batch and the MCP batch tool take coalesce_parameters (default
false). With it, each run of consecutive plain parameter edits
(parameters.change with only a name and an expression, or with changes) is
set as one parameters.change {changes}: one rebuild for the run. Any other
step ends a run, so later steps see the design up to date. Every step
still gets its own result (coalesced: the run's length); the run is one
undo step. A run whose combined edit is refused (a new parameter, which
changes can't make; a bad expression) runs step by step, so a refused edit
is still named by its own step. The app's off-thread evaluation computes
the run the same way. The grouping is solidcraft_engine::batch_params,
shared by both runners.

without printing the token. The app also writes `<port>.pid` beside the
token file (its process id and, on Linux, its start time) and removes
both at exit; when that process has exited, the error says the token
file is stale. The process check runs only after a refusal, and the

Rebased onto main as one commit (was 120d26f7, df488f9a, db9d1073 plus
merges of main).
- A request the app reports as still running (#1618) is waited for on the
same connection through `control.pending`; past the wait the error says it
was not cancelled and will still apply (or only write its file), later calls
are not sent behind it, and the new read-only `pending` tool returns its
result once it lands.
- A failed batch says what really happened: `rolled_back` only when the
design is back where the batch started (as #3288 / #3242 on main: the app's
`rolled_back` is believed; for an older app, every completed step undone;
only a rollback asked for is reported as one), plus `applied`, `not_run` and
`failed.still_running`.
- A batch step may name a tool (set_parameter, list_commands,
describe_command, execute, measure, inspect_design, undo, redo, export, save,
open, new_design, crash_reports); screenshot, body_topology, batch and
pending are refused before anything is sent.

connection and at once (the connection's own thread answers it, also while it
is busy with a timed-out request): every request the app has been sent and not
answered yet, oldest first, with its connection, id, method, command id (or a
batch's step count), seconds since it arrived and whether it still waits its
turn. A timed-out request stays listed until the app answers it, also after its
connection closed. Parameters are never shown.
The window marks a request started when it takes it (ControlRequest.started),
which tells queued from running. The MCP server gets a read-only `running` tool.

* claim: #3242
* MCP batch: rollback restores the design the batch began in (#3242)
A failed batch with rollback: true reported rolled_back: true even when the
design never went back. Two defects, both fixed:
- file.new (and any document-replacing command) replaced the session with it,
taking its checkpoints down too, so a batch that failed after file.new had
nothing to restore. Session::replace_design now carries the checkpoints over
to the fresh session: the checkpoint belongs to the batch, not to the
session that happened to be holding the document.
- rolled_back echoed the requested flag. It now reports whether the design is
actually back: the app answers engine.batch with a new restored field, and
the MCP tool reports restored && rollback. An app that predates the field
falls back to undone/completed.
* Batch: answer with main's rolled_back field after the merge (#3242)
Upstream #2900 put the real restore check on engine.batch as
`rolled_back` while this branch named it `restored`; the merge kept
main's control test and this branch's field, and CI caught it.
Standardize on main's wire name: the app answers `rolled_back`, the
MCP tool reads it (fallback for older apps unchanged), docs and tests
follow. The checkpoint carry-over across file.new is unchanged.

* joint.inspect: what each joint is attached to, for agents
A read-only `joint.inspect {joint?}` gives each joint's definition: for each
side the occurrence, its component and path, the snap as saved, and what
each persistent face/edge name refers to (the feature that made it, and the
sketch and curve a swept side came from), whether the origin resolves and
why not; plus kind, offset, angle, flip, values with limits, expressions,
the motion links it is in, and its solve errors and conflicts. Its id ends
in `.inspect`, so agent gates treat it as reading only.
MCP `inspect_design` includes the definitions when the design has joints
(`joints: false` leaves them out). joint.list and joint.inspect share the
motion-link JSON.

The schema RFC's spike (plan/schema-spike.md). solid.box and solid.extrude get
typed contracts with generated JSON Schemas (2020-12), checked in front of the
unchanged handlers by a per-session level: off (the default, which changes
nothing), warn (the call runs and gains param_warnings) or strict (the call is
refused and the design left alone). Also engine.describe and the MCP tool
describe_command, `solidcraft-cli mcp --param-check off|warn|strict`, a
FeatureResult type for feature replies, and an env-var audit recorder
(SOLIDCRAFT_PARAM_AUDIT) used to check the contracts against every test.
Local spike branch; not for upstream as is (see the results report).

* Parameter contracts: put the audit recorder behind a feature; drop two ignored test keys
The audit recorder is now on only in a build with the engine's `param-audit` feature
and `SOLIDCRAFT_PARAM_AUDIT` set. Its code is still compiled, linted and tested without
the feature. `scripts/param_audit.py` summarises a test run's audit logs, and the schema
module's docs give the steps for converting a further command.
Two tests passed keys their command ignores, which the audit found: `position` on
`solid.box` (`hole_face_tests.rs`) and `symmetric` on `solid.extrude` (`face_tests.rs`).
Both are removed, so the tests build what they always did. Comments no longer call
the contracts a spike.

* Snapshot: draw a see-through appearance see-through, and give the CLI --body, --tool and --section
A headless picture dropped a body's opacity: the scene carried only a colour, so a design with
a translucent appearance was drawn opaque by `solidcraft-cli snapshot`, by MCP screenshots and
in a design's thumbnail, although the window has always drawn it as glass. There was then no
way to look at the body a cut would remove inside the material it meets: only a volume to
measure and reason about, which hides exactly the errors a picture makes obvious (a tool that
stops short, or lands in the wrong place).
- `SceneMesh` carries the body's opacity; `view::build_scene` takes it from the design
(`model_body_opacity`), and a selected body stays solid so the selection colour reads.
- The GPU capture routes a see-through body into the scene's glass at its own alpha, as the
viewport does; the CPU rasterizer draws the solid bodies first (they own the depth buffer),
then the see-through ones blended over them, far sides before near sides and without writing
depth, so what lies inside shows and a line between the two is not hidden.
- `snapshot --body NAME:opacity=0.3,color=#rrggbb`, `--tool NAME` (that body solid in the tool
colour, the rest see-through) and `--section z=27` run the commands the app itself runs
(`appearance.assign`, `inspect.section`): the options are shortcuts, not a second renderer.

* Tests: measure the tool colour as it is drawn through a see-through target
The tool-colour filter was derived on paper and demanded a red more than twice either other
channel, which the target in front of it tints away (measured: (200, 108, 85) through opacity
0.3); and the colour check painted the tool, which a solid target hides.

* fmt
* Snapshot options: strip the colour's # rather than slicing it; README
Slicing `value[1..]` on an input-derived string is what the house rules ask us not to write,
even where a length check has already made it safe. The error a failed assignment reports now
names the body rather than claiming it came from --body, since --tool reaches it too.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* --tool: assign the bodies around the tool in groups, not one command at a time
Each appearance.assign is an undo step with a document snapshot behind it, so one per body
made --tool cost grow with the size of the design for no reason: the bodies around the tool
all get the same opacity, and the ones that share a colour can be named in one call. A design
whose bodies all wear the default grey now costs two commands whatever its size.

* Rasterizer: say where its glass and the GPU's differ
Splitting each see-through body by facing orders its own two layers; it does not sort across

* Imports become components: a STEP assembly's tree as nested components (#1386)
Every imported file (STEP, IGES, 3MF, STL, OBJ: inserted, dropped, opened as a
design, or file.insert_step / file.insert_mesh / doc.open from scripts, the CLI
and MCP) now comes in as a new component named after the file, with its Import
feature inside it. A STEP assembly's products become nested components; a part
placed more than once is one component with an occurrence per placement, and
the Import feature skips the file's later copies (`skip`, format 21 note). The
contents are held as one rigid group (rigid joints, glyphs hidden); moving an
inner part is refused until component.unlock ("Unlock Contents") releases it.
Y up turns the import's component. Replies report component, component_name
and occurrence. Undo is one step; designs with loose imports are unchanged.

Measure now reads the picked item's exact shape (cylindrical faces, circular and arc edges,
sketch circles, arcs and lines, profiles, planes, points):
- A circle, hole or arc shows Ø, R and its length (circumference, or arc length and angle).
- A slot (a sketch profile, or a half-cylinder end of a slot in a solid) shows its width,
centre-to-centre length and overall length.
- Two items where one is round measure from the centre or axis by default (axis to axis,
axis to plane, edge or point), with the closest and farthest distances listed too; the
panel switches between centre, min and max, and the canvas line follows.
- inspect.measure and MCP `measure` (new `items` argument) add diameter, radius,
center_distance, min and max; existing fields are unchanged.

solidcraft-cli snapshot takes --camera JSON and --view with a saved view name (through view.apply, as the MCP screenshot does), plus --no-grid and --no-axes; the MCP screenshot and ui.render take grid/axes, the headless render skips a hidden origin axis, and the app's ui.render follows the Grid and Origin switches. Closes#1245.
file.insert_step and doc.open on a STEP file take `up` (turn a Y-up file so its up is +Z) and `names` (names for the imported bodies). The MCP tool and the app's control requests pass them through; an import without them works as before. Tests in the kernel's STEP reader, the engine, MCP and the file-load UI; docs/step-import.md and docs/mcp.md describe both.
A solidcraft-mechanisms agent skill with a worked example that a test replays through the MCP server (the actuator follows the hinge with the stated stroke and the drive stops at the rod's limit); the skills index and docs/mcp.md list it.
The bridged MCP server starts when no app is listening, says so in its instructions and in each tool error, and connects on the first call after the app starts. A batch that could not be sent says the app is not running. docs/mcp.md describes it.
Lands the Render workspace (R3), bounded preview-image jobs with cancellation and atomic PNG export (R4a), and opaque PBR looks as one change.
- Render workspace: an overlay-free product preview on the installed GPU device. Returning to Design restores its camera. render.scene and render.settings.apply are added.
- Image jobs: render.preflight/start/status/cancel/export run bounded CPU preview jobs. Export captures the job, overwrite choice and document, and checks the caller's file scope before writing.
- Opaque PBR: looks can carry metal fraction, roughness and dielectric IOR. The product viewport and preview PNG use them; geometry and mass are unchanged. The v1 catalog export refuses PBR rather than dropping it.
- Render setups and PBR looks are saved under design format 21. Labels are in en/de/ja/ko/zh/ru.

A design carries metadata (format 21): project, part number, revision, author, organization, description and license, plus other tools' data under reverse-DNS keys, kept as written. Edited in the Design Properties window (Document Settings), set by document.metadata.set, reported by inspect_design, and written into STEP, IGES and 3MF where the format has a place for them. Translated, with tests.
Rectangular and circular sketch patterns stay linked to their source: editing the pattern's count, spacing or the source geometry updates the copies, and the copies keep their point and radius relations. Patterns are saved under format 20; older designs keep their independent copies.
On Windows the temporary folder often has an 8.3 short name, which the path scope refuses. vfs::long_names spells folders SolidCraft derives from the environment with long names, and the MCP scratch folder and the recovery folder use it, so screenshot without a path and the recovery commands work there again.
PathScope stores its roots canonicalised (\\?\ on Windows, /private/var on macOS), so the default-folders test now canonicalises scratch_dir() before looking it up, like the recovery folder on the line above.
The same fix came in from @Karl-VonRichter in #969, found on macOS.

A design with components and joints exports as a URDF robot description (file.export to .urdf, the MCP export tool, solidcraft-cli run --out, File > Export URDF...). It writes one binary STL per component in metres, links with mass, centre of mass and inertia from material density, and maps rigid, revolute, slider, cylindrical, pin-slot, planar and ball joints to URDF joints or short chains. Loops, broken joints and loose parts are reported as warnings. Options: mesh_prefix, effort, velocity. Docs in docs/urdf.md.
The app's control protocol gets engine.batch: the steps run in one request (so one frame), each as engine.execute runs it, stopping at the first failure and rolling back to the checkpoint by default. The MCP batch tool sends it to a running app (with the control token), is never resent after a lost reply, and falls back to step-by-step when the app refuses (agent cursor shown, or a step loads a file). A batch may take up to an hour to answer.
solidcraft --control PORT writes a random per-launch token to a user-only file (<data>/control/PORT.token; 0700/0600 on Unix, icacls on Windows; SOLIDCRAFT_CONTROL_TOKEN overrides) and refuses any connection whose first request lacks it. mcp --connect, the demo and packaging smoke clients send it. MCP execute/batch/open/save/export/screenshot are annotated destructive and open-world, new_design destructive. Docs: control-protocol.md, mcp.md, AGENTS.md, pending release note in releasing.md.

Agent tool calls (MCP, and bridged control requests carrying allow_paths) reach files only in the open design's folder (strictly inside home or the temporary folder, not in a hidden folder, and never its hidden files), the app's recovery folder, the server's private scratch folder and each --allow-path; --allow-any-path lifts the limit. Paths are resolved first, so .. and symlinks that lead out (including a save through a link, #845) are refused. On Windows, UNC, device, NT, verbatim non-drive, drive-relative, alternate-stream, reserved-device and 8.3 short-name paths are refused before any file system call, and the resolved path must be on a local drive. doc.recovery_discard and doc.recover {discard} delete only real recovery entries. Docs: mcp.md, control-protocol.md, README.
The MCP server instructions now point to `body_topology` for finding edge points (there is no `list_edges` tool), with a test that every tool the instructions name exists.
MCP execute accepts verbose: false too, using the same compact reply as batch (#599), and the MCP docs gain a section on compact replies.

New view.apply command restores a named view, a standard view or any camera (view state, not an undo step); the desktop viewport follows it and the browser's Restore uses it. The MCP screenshot tool takes a named view or a camera. Un-ignores the #528 regression test. Fixes#528.

MCP batch takes verbose: false for compact replies: feature steps leave out the full body list and sketch steps the ids they repeat outside created. Feature replies now also list changed_bodies and removed_bodies next to created_bodies, so a compact reply still shows every effect of a step. Un-ignores the #530 regression test. Fixes#530.

Hidden bodies, occurrence placements, sketches and origin items are saved with the design and come back when it is reopened. Visibility is still not an undo step, but hiding or showing something now counts as an unsaved change. Additive field under format 16. Fixes#531.

Fixes#374. Feature replies gain created_bodies: the bodies the new feature made, apart from the ones it changed or that were already there. Documented in the execute tool description and docs/mcp.md.
