A save with `precision` rounded only the native document, and drew the
embedded preview and the `pdfCompatible` PDF from the exact document.
An app reading the PDF showed paths up to 0.5 pt away from what
VectorCraft reopens at `precision: 0`.
When `precision` is set, the preview and the PDF are now drawn from a
copy of the document rounded as the file holds it. For an older version,
placed documents in that copy become groups of their art first, as the
file stores them, so their rounded art shows too.
Tests: a save at precision 0 puts the path in the embedded PDF on the
rounded coordinates, and its preview matches the one drawn from the
saved document; the same for a version 3 save of a placed document.
Native files store every anchor and handle as a full double, such as
3.4876474632797176, so a file of traced art is larger than it needs
to be.
document.save, file.saveAs, file.saveCopy and file.saveAsTemplate take
precision (0 to 9) for native files. The save rounds the anchors and
handles of path objects, Live Corners' uncut outlines, blend spines,
envelope outlines, Intertwine areas and brush art to that many decimal
places, in the layers, symbols, graph designs, patterns and opacity
masks, and in the art that placed documents become in files for older
versions. Colors, transforms, opacity and type are written exactly.
Without precision the file is written as before, and Save does not
remember the option. A .ai file, saved or exported, ignores precision.
The VectorCraft Options dialog shows no row for it.
A save given precision beside the path for a format that does not read
it (SVG, PDF, .ai and .ait) says so in its warnings, as it does for
compress, version and preview. MCP save_file passes precision on to the
save as it passes the other native options, and its schema, description
and docs/mcp.md list it.
A native save was pretty-printed when the document had at most 2,000
layers and objects and its compact JSON was at most 1 MiB. Pretty
printing puts every coordinate on its own indented line, so traced art
with few paths and many anchors could pass that check and be written at
about five times the size of its compact JSON.
The 1 MiB limit now applies to the pretty-printed document, indented as
the file holds it and in the form the save writes: version 1 anchors,
and placed documents expanded for older versions or Include Linked
Files. Documents whose pretty-printed JSON is over 1 MiB are saved as
compact JSON, even when their compact JSON is under it. The 2,000-object
rule and compressed saves are unchanged. docs/mcp.md describes the rule.
file.saveAsTemplate with format ait and aiVersion: "7" wrote the
legacy PostScript .ai of version 7 under the .ait name: for a
one-artboard test document, a 7,556-byte file starting %!PS-Adobe-3.0.
The web's Save as Template dialog showed the .ai Version menu for
.ait, whose Legacy (version 7) choice set aiVersion 7.
aiVersion 7 for a .ait is now an error, "aiVersion 7 writes legacy .ai
files; a .ait template is always PDF-compatible", and nothing is
written. The 17 catalogs that translate every message have a row for
it. The dialog shows no Version row for .ait, and aiVersion "pdf"
still writes the PDF-compatible template.
Docs: docs/mcp.md, docs/target-app-parity.md, docs/file-format-parity.md
(two stale rows for .ai and .ait removed).
Type is written as version 7 text objects (§15): point type, area type and type on a path, with
fonts by PostScript name re-encoded to Windows-1252, and each run's paint, size, scaling,
tracking, leading, alignment and indents; type 8-bit text can't hold (or all, with outlineText)
is outlines. The format hides only layers, so hidden objects go to a hidden layer above their
own (hiddenObjects "layer", the default), are left out ("omit") or show ("visible"). The .ai
reader reads legacy type (To … TO, TE, %AI3_BeginEncoding) and ignores Ar; the import fuzzer
gets legacy type tokens.
aiVersion 7 saves through the legacy writer, one file per artboard; range picks the artboards
and document.save writes them again. Appearances are expanded first. Transparent images
(see-through pixels, opacity or a blending mode) are flattened with the art under them into
opaque images clipped to where they change it (transparentImages "flatten", the default), or
left out ("omit"); both warn.
Save serializes JSON straight into the compressor and writes images from their Arc into the
file; open reads each image into its own buffer, and NodeKind reads its tag first instead of
buffering every node. Already-compressed images are stored rather than deflated again in the
same gzip stream. Limits apply per section, so any file VectorCraft writes opens again. Data
Recovery writes each image once, content-addressed, instead of every interval. Native files open
on a background thread. Files stay readable by main both ways; JSON-only saves are identical.

The Libraries panel was a placeholder: it invited dragging art onto it,
but nothing happened. It now keeps local libraries (no account, no
cloud), as Illustrator's Libraries panel does:
- drag art off the canvas (or a swatch) onto the panel to add it, or use
+ to add the selection's graphic, fill or stroke colour, character
style or paragraph style;
- drag a graphic onto the canvas (or double-click it) to place a copy,
click a colour to paint the selection through the active Fill/Stroke
proxy, click a style to apply it to the selected type;
- the library picker and the panel menu create, rename and delete
libraries; each is a .vclibrary file in a Libraries folder next to the
preferences (session-only in the web app, headless sessions and runs
without preferences).
Engine: library.list/get/setCurrent/create/rename/delete/add/use/
removeItem. A graphic is stored as a native document with a thumbnail:
adding copies as Copy does and placing pastes as Paste does, resources
and swatch-name conflicts included. Using a style adds it to the
document and applies it in one undo step.
Clipboard::to_document gave its layer the id u64::MAX, which made a
saved copy overflow Document::fix_next_id when read back; the layer now
takes an id above the objects', and fix_next_id saturates.

- document.save / Save As / Save a Copy to a native or .ai file take
separateArtboards + range (also write <name>-<artboard>.<ext> per artboard
beside the master file, holding that artboard and the art touching it; the
result lists every file), includeLinked (linked images keep their files' own
pixels), embedProfiles (ICC profiles loaded from files that the document is
tagged with; opening installs them where missing) and pdfCompatible (native:
also carry a PDF of every artboard; .ai: false writes blank pages around the
native document). .ai files also take compress (compression.compressText).
- File > Save As to a native or .ai file shows the options dialog (VectorCraft
Options) after the save panel: Save each artboard to a separate file (All or a
range), Include Linked Files, Embed ICC Profiles, Create PDF-Compatible File,
Use Compression, Preview; the web's Save As dialog shows them too. Save, Save a
Copy and Save as Template reuse the options as last saved.
- Format: optional "profiles" and "pdf" members (load_file, pdf_content),
SaveOptions.include_linked/profiles/pdf; files without them are unchanged.
- Changed test: tests_aisave::save_as_ai_writes_a_pdf_that_reopens_editable now
confirms the options dialog Save As .ai shows before writing.

- With Preferences > File Handling > Enable Background Save / Export on, File >
Save, Save As, Save a Copy and exports encode and write a snapshot of the
document on a worker thread; the call returns at once ({path, background}).
- The status bar shows a spinner and what is being written; ui.inspect lists
the running jobs under `background`.
- The document takes the path and counts as saved as of the snapshot once the
file is written: edits made meanwhile keep it modified.
- Quit and Close wait for running saves; the Save Changes dialog saves at once.
- The host gives a thread-safe writer (Services::write_shared, atomic on the
desktop); without one (web, tests) everything runs at once as before.

- 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.
