Optional content groups become layers (in paint order, shared by every page)
with their name, default visibility, print usage and lock; art outside them
goes to a layer per page. Art that is off isn't lost: an update appended to
the file drops its /OCProperties so the interpreter draws every group, and
the marked-content sequences found walking the content (checked by tag) route
the art to its group's layer, which comes in hidden. A form hidden by its own
/OC keeps the file as it is. document.open layers: false keeps one layer per
page of only what shows (Save then asks for a name).

- Format v3: optional gzip (Preferences > File Handling > Use Compression, or
document.save {compress}); compressed files open by their magic bytes, legacy
ones too.
- Every file write goes to a temporary file renamed over the target (engine
writes and the desktop app's writer), so a failed save keeps the old file.
- Only the images the document uses are written.
- Document keys from newer versions are kept (Document.extra, flattened).
- Assigned colour profiles are a real field (Document.color_profiles),
migrated from unknown.colorProfiles on load.
- document.save {version: 1|2} writes files older versions open; {preview}
embeds a PNG of the first artboard of at most 256 px.

File Info's dates come from the clock, so documents made or saved a second
apart differed: journal_replay_reproduces_document and
rich_fixture_satisfies_invariants_and_undoes_to_blank failed at random.
One approach for every clock-derived date: it is a command input that
defaults to now, and the journal records the value used.
- file.new takes created? and document.save / file.saveAs take modified?
(Unix seconds, or null for none; default now), through date_param /
clock_date on the one save path (save_with), so Save, Save As and the
UI's save stamp alike; Save a Copy still leaves the dates.
- Their journal entries always record the date used, so replaying the
journal makes the same document whenever it runs. Actions recorded from
the journal (Session::journal_for_action) leave those dates out, so
playing an action later dates the document then.
- Test fixtures date their documents fixtures::CREATED, and the MCP
property test dates its local document as the headless one, so
documents built at different moments compare equal.

A PostScript file (a .ai saved in an older format or without PDF
compatibility, or an .eps, plain or with a binary header) is refused by any
name with a clear message instead of a parse error (there is no PostScript
importer yet). An .ai whose pages are only placeholder text over the editor's
private data (PieceInfo AIPrivateData) is detected and refused with advice to
save it with PDF compatibility, instead of opening the placeholder.
vectorcraft-pdf: is_postscript(), PdfError::PostScript / PlaceholderOnly.

DeviceCMYK and CMYK ICC colours import as CMYK and a file painted mostly in
CMYK opens as a CMYK document (with CMYK default swatches); DeviceGray
imports as Gray; Separation and DeviceN inks become global spot swatches
(their 100 % colour from the alternate space: CMYK, RGB, Gray or Lab) that
the art links to at its tint, /All links to Registration and process
colorants make CMYK. Shading stops keep their model and ink links the same
way. Inks mixed in one DeviceN colour, or spaces that can't be told apart,
import as RGB (with a warning for the mix).
document.open takes colorMode (rgb | cmyk) to open any file in that mode,
converted as file.documentColorMode does (its conversion is now shared).

Opening or placing a PDF or .ai with several pages or a password shows the
Import PDF / Place PDF dialog: a page preview with page navigation, Pages
(All or a range) when opening, Crop To (Bounding Box, Art, Crop, Trim, Bleed,
Media) and a password prompt for encrypted files.
- vectorcraft-pdf: ImportOptions.pages / crop / password, CropTo, info()
(pages, sizes, rotation, boxes); NeedsPassword / WrongPassword / BadPage
errors; images keyed by content so placed pages merge safely.
- document.open takes pages, page, cropTo (or crop) and password;
document.pdfInfo (query) lists pages and boxes, reports needsPassword and
renders a page thumbnail.
- file.place and file.place.info read only the page placed and take every
PDF box as crop (art, trim, bleed, media besides crop and bounding) and a
password; the UI's File > Place asks with the dialog when no page is given,
keeping Link, Template and the other place params.
- testkit::pdf writes hand-made PDFs with page boxes and RC4 encryption.

Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.
- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
unimplemented and unreachable; clippy.toml allows them in tests, and
integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
the document back and returns EngineError::Internal; a panicking tool is
reset; the MCP server answers with an internal error and keeps serving; the
UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
return Result (JPEG/WebP errors used to write empty files),
FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
README pointer and a PR template checklist.

The sweep compares a curve with another segment over a y-span shorter than
its tolerance by bounding boxes only, so an edge rising by less than that
tolerance (e.g. a rectangle edge cut through a circle's cap, whose computed
intersection end sits ~1e-12 off the horizontal) was mis-ordered and the
result lost a corner: xor/difference/area disagreed by up to 10%. Every
sweep input now snaps on-curve y values within the tolerance to one level
(handles follow and are levelled with their anchor), so such edges become
exact horizontals, which the sweep handles exactly.
- tests/regressions.rs: the six minimal failures found by the properties,
the root cause in isolation, and the self-crossing "star" polygon.
- The star-polygon strategy rejected no angular step of half a turn or
more, so it sometimes drew self-crossing polygons (the shoelace failure).
- Property suites run from a fixed seed (PROPTEST_CASES / PROPTEST_RNG_SEED
still override), so CI cannot fail at random.
