A PDF-compatible .ai keeps its art past the artboard edge unclipped (#646),
and its pages are laid out in a row 36 pt apart. Art that a page draws far
to the left of its artboard (notes beside a design, say) then lay over the
page before it. There it was taken for that page's art: the check against
the editing data found art its layers don't have and opened the file as
its PDF part, without the art outside its artboards, and place_pages left
that art behind when it moved the pages.
Such a page now moves right until its art clears the art before it.
Plain PDFs (clipped to the page) keep the 36 pt gap.
A .ai file with placed files opened from its PDF part (no guides, no sublayers,
no hidden objects), because the editing-data reader stopped at them.
- Lexer: a placed file's preview section is one token (it was skipped).
- Reader: %AI5_BeginPlace ... ~ becomes a linked image with the file's path,
showing the preview the data keeps of it (premultiplied ARGB, capped at
MAX_PIXELS, its rows checked against the bytes there), in its place: the
matrix takes the file's pixels from the canvas, where they start at the point
of art space's origin. A placed file without a preview, a path or a matrix
still makes the file open from its PDF part.
- The open result lists one warning saying linked pictures show the
low-resolution preview until their files are found (rows in the catalogs).
- Engine: a link nothing is known of whose image shows a preview is read where
it is found as the document opens, into the image's bounds, and isn't
reported as modified.
- Tests: lexer, reader (hand-written data), engine open with the link missing
and found, fuzz tokens.
- Docs: file-format-parity, target-app-parity, gaps, ROADMAP.
A PDF-compatible .ai opens on its trim boxes, its editor's artboards,
with the bleed boxes round them as the document's bleed (#1349). A PDF
saved with its editing data (#1345) keeps that data under
AIPDFPrivateData keys, which has_illustrator_data didn't look for, so
such a PDF with a bleed still opened on its crop box: the artboard took
the bleed in and the editing data was refused as being for a different
page. has_illustrator_data now finds either key. has_private_data, which
also decides how a page is clipped, is unchanged.
Test: a_file_with_a_bleed_opens_on_its_artboard_with_the_bleed_round_it
(the .ai case, and the same hand-written file with AIPDFPrivateData).
A PDF saved with the reference app's editing data keeps that data in
streams named AIPDFPrivateData1, AIPDFPrivateData2, ..., where a .ai
file uses AIPrivateData1, AIPrivateData2, .... illustrator_data read
only the .ai names, so such a PDF opened like any other PDF: plain
groups opened ungrouped, and hidden objects and guides were missing. The
import gave no warning that the PDF's editing data went unread.
illustrator_data now reads the AIPDFPrivateData streams when the file
has no AIPrivateData1, and the PDF opens from its editing data as a .ai
file does. editingData: false still opens it like any other PDF.
has_private_data still looks for AIPrivateData keys only.
layered_ai also returns whether it read the layers. When it did, art
reaching past a PDF's page opens whole, and through_editing_data drops
the PDF importer's note that such art was clipped (PAST_PAGE_NOTE, now
public) as it drops the off-artboard note. When it didn't, both notes
stay. On main, a .ai whose editing data can't be decoded or has no
layers opened from its PDF part without the off-artboard note.
testkit::ai::pdf writes the .ai file of testkit::ai::ai with the PDF
key names. The editing-data tests open it as a PDF, and the import fuzz
test opens the damaged sample as a PDF too.
Docs: the document.open params, docs/mcp.md,
docs/file-format-parity.md, docs/gaps.md (G9: the export direction of
#868 remains), one evidence line in docs/target-app-parity.md, and #868
moved from layer structure to editing data in the File formats row of
docs/target-app-parity.md and in docs/roadmap.md.
A PDF-compatible .ai with a bleed writes its PDF part's page as the
artboard grown by the bleed: the crop box takes the bleed in, the trim
box is the artboard and the bleed box the bleed. The importer made the
crop box the artboard, so the bleed opened as more white page with no
bleed guide; and since the editing data's artboard no longer matched
that page, its layers weren't read either ("its editing data is for a
different page").
Opening a PDF-compatible .ai with the crop box (the default) now takes
its trim boxes as the artboards. Any import on the trim boxes (Crop To
› Trim, for a PDF too) sets the document's bleed to how far the bleed
boxes reach past them on each side (ISO 32000-1, 14.11.2), kept to
0–72 pt, and the document read from the editing data keeps it. Art in
the bleed shows outside the artboard, within the bleed guide. Plain
PDFs still open on their crop box by default, and Place is unchanged.

Since #1025 reads global colours, more Illustrator EPS files open through
their layers, and for one reported file that gave a worse result than its
page did in 0.8.0:
- the page became the editing data's artboard (344 pt tall) instead of the
file's own bounding box (358 pt), cutting off art reaching above it. An
EPS whose page is its art's box now keeps that page on the layers path
too, as it does on the page path.
- prune_unseen took out text objects the page does draw: a red stroke
stacked over a dark red one differs from it by less than the lightness
margin, so the page looked no different without it. Pruning now weighs
each text object by colour (any of red, green, blue more than 64 apart);
the page check itself still compares by lightness, so colours written
as their CMYK equivalents still match.

When a .ai's layers can't be read from its editing data yet, it opens as
its PDF part, which lists the artboards as pages; those were laid out in
a row, so a grid of artboards (or any other arrangement) was lost. The
editing data's artboards are now read even then (ai::artboards, as far
as the reader gets) and, when there are as many as pages and of the same
sizes, each page goes where its artboard is, with the art on it (the art
of a page: the objects mostly on it, else nearest it). Otherwise the
pages stay in a row as before.

A .ai or PDF whose spot colours are defined in Lab opened them wrong:
- the PDF part gives such an ink an ICC Lab profile as its alternate
space ([/ICCBased profile], 3 components), which was read as RGB, so
the Lab values were clamped into wildly wrong colours (PANTONE 249 C
came in yellow). A profile whose Alternate is [/Lab ...], or whose
header names the Lab data colour space, is now read as Lab;
- the editing data writes them as `c m y k L a b (name) tint 2 Xx`,
type 2 being Lab, and only the CMYK equivalent was read. Type 2 now
gives the Lab colour, in the swatches and on the art.

A .ai in PostScript form went only to the PostScript interpreter, which
stopped on the first operator its missing prolog would define
(`Adobe_packedarray`, `Lb`, `Np`): files from Rhino and other CAD apps name
the procsets without including them.
- Such a program is its own editing data: when it has layers
(`%AI5_BeginLayer`) and no private data, the editing-data reader reads it,
compared with the page when the program runs, from the layers alone when
it can't be run. If the layers can't be read either, the error says why.
- The reader takes the legacy ten-operand `Lb`, ignores flatness `i`, and
uses the bounding box as the page when nothing else says where it is.
- Tests on synthetic files; fuzz fixture and hostile-program layers added.

The editing-data reader stopped on `Xk`/`XK` (global process colours) and
on `p`/`P` (pattern fills), so the file fell back to its PDF part, which has
only the top-level layers.
- `Xk`/`XK` read like `Xx`: a global swatch (not a spot ink), linked at its tint.
- `%AI3_BeginPattern` sections are read by a reader of their own into
pattern swatches (tile from `(name) llx lly urx ury`, art in pattern space);
`p`/`P` fill or stroke with them, placed by the operator's matrix. A pattern
it can't read whole still makes a fill with it unreadable, as before.
- Tests on synthetic editing data; fuzz tokens and fixture extended.
