The face's triangles are cut along the plane, split:<name>:a on its
negative side and :b on the other, both on the face's surface, with the
cut as a new edge between them and the face's edges cut where the plane
crosses them. Applied after the merges; the B-rep is unchanged.

A Merge makes adjacent faces of a body one virtual face in what meshers
take from it (tessellation tags, faces, surfaces, edge and vertex names):
the edges inside it are dropped and the pieces of an edge it leaves are
joined; the B-rep is unchanged. Design::merged applies merges after the
partitions and lists the ones that fail as feature errors.

hex_mesh_swept_cells lays out one cross-section for several cells: every
cell's walls (its cut faces included) are imprinted together, every cell's
levels are levels of all, one interval assignment and one set of layers,
and each region of each level interval is filled by the cell it lies in.
Cells meet node for node across every cut, T-junctions included.
mesh.cells sweeps the cells of each design body together first and meshes
cell by cell only what does not sweep together (saying why); the reply
gives every cell's volume, scaled Jacobian and edge ratio.

SolidCraft names the pieces of a split body by stacking suffixes
(Bracket (1) (1)' (1)). On opening a design, the pieces of one body are
named <body>.1 … <body>.N, ordered by centroid, so the tree, tooltips,
forms and picks read as one part with numbered cells.

The design file stores no measure to compare with, so the rebuild's own
failures are the guard: each failed feature lists the bodies it names (all of
them when it names none), and geometry.open replies with a warning per failure,
which the window shows with the open.

Design::partitioned cuts the bodies as opened by planes in order (SolidCraft's
split_by_plane, in memory). Cells are <body>/a and <body>/b by side of the plane;
the two faces of each cut are partition:<name>:a and :b, and every other face
inherits the name of the face it is a piece of (<name>#k when a cell holds
several pieces). A cut that misses or names an unknown body is reported as a
design error, not fatal.

file.open, geometry.open, geometry.import.mesh and reopening a model's
geometry read through the io crate's file edge instead of SolidCraft's
vfs, so in the browser they see the files the page holds (the same
store saves write to). Natively it is the same capped regular-file read.
fieldcraft-geometry drops its path-based readers (read_file,
open_design_file, read_3mf_file): it works on bytes, and reading files
is the io crate's job.

* modelcraft-io: the .modelcraft file (modelcraft/1), atomic writes, autosave storage
A stored ZIP of a manifest (format tag, geometry sources with SHA-256,
part sizes and hashes), the model definition as stable pretty JSON, the
mesh and geometry tags in a compact binary part, and the journal one
command per line. Reading caps every size, checks every checksum and
replays the model through its checked methods. Model::without_mesh and
empty mesh fields left out of the model's JSON; geometry::read_file.

* engine: undo/redo on the journal, file.open/save/save_as, autosave and recovery
CommandSpec gains a kind: Model commands are journalled and become undo
steps; Session commands (file.*, edit.*) manage the session. Undo history
is bounded by steps and estimated memory. Geometry sources are recorded
with content hashes and reopened on file.open (missing or changed files
are warnings). Desktop app autosaves every 30 s and reports recoverable
models; Ctrl/Cmd+Z and Shift+Z/Y undo and redo.

* simplify: shared path parameter, one load path for open/recover, history accounting in History
Session commands skip the per-command model copy; saved revision is an
Option; journal written from borrowed entries and read without an
intermediate tree; backups copied by the file system; recovery lock and
error helpers; geometry file wrappers use read_file.

* geometry: open .solidcraft designs, rebuild them and keep persistent face names
open_design(bytes) reads a design (container or JSON) with solidcraft-io, rebuilds its
timeline with solidcraft-doc and returns its bodies; each Shape carries SolidCraft's
persistent face names by B-rep face index, so a face keeps its name through a parameter
edit. sample::plate_design builds a parametric test plate in code.

* engine: geometry.open, geometry.bodies and geometry.tessellate
The session holds the open design (shared, restored on a failed command, journalled when
it changes). Hostile-params coverage includes non-files, missing files, oversized paths and
extreme tolerances against an open design.

* geometry: open_design_file reads through SolidCraft's bounded file access; simplify
The engine's hand-rolled capped read is replaced by open_design_file, which uses
solidcraft_io::vfs::read (refuses non-regular files before opening, works on the browser's
in-memory files). Drops the duplicate size check, simplifies the sample sketch and the
design-change test in Session::execute.
