Review found behaviour the tests let break unnoticed (each was a
surviving mutant, and each new test fails on it):
- black padding bits: a run reaching past the row would stop symbol
coding on many scans;
- Annex A's 32-bit range and PREV at exactly 256, where a decision would
go uncoded: coordinates past 4,435 on a 12,000-pixel-wide and a
10,050-row page, and the contexts of 4436's coding;
- marks joined at a corner are one mark; 256 pixels a side is a symbol,
257 is left to the generic region;
- the run and row caps, at and past them.
The roadmap's status line for this change now comes first, and the
"about a third smaller than Group 4 on scans" figure is replaced by what
was measured: 27-33% on the same pages with scan-like noise added.

pdfcraft_filters::encode_jbig2 stores each distinct mark of a 1-bit
image (8-connected black pixels, at most 256 a side) once, as a symbol
in a symbol dictionary, and places its exact copies with an immediate
lossless text region that refers to it. Larger marks, and in a second
plan marks that occur once, go to a generic region over their box. It
keeps whichever of that and the generic coding (encode_jbig2_generic,
unchanged) is smaller. Only exact copies share a symbol, so the stream
decodes to the same bits.
Written from the JBIG committee's ISO/IEC 14492 Final Committee Draft:
6.4 and 6.5 (text region and symbol dictionary decoding), 7.2, 7.4.2
and 7.4.3 (segment headers and syntax) and Annex A (the integer coders,
checked against its worked example and Table A.1).
On six pages of rendered 300 dpi text the output is 28% of the generic
coding's size and 17% of Group 4's, at about 100 ms a page; hayro-jbig2
and Poppler (pdfimages) both decode it to the original bits. Scans,
whose copies of a letter are seldom identical, gain little: that needs
refinement coding. A dictionary shared between pages (/JBIG2Globals)
is a further step.
The optimizer's Monochrome Images > JBIG2 (lossless) and doc_optimize
mono jbig2 use it.

Copy Image and Copy Image in Original Format go through Export's
decoder, which reads JBIG2 now, so the view.copy-image parity note no
longer lists JBIG2 as missing. docs/target-app-parity.md's optimize row
lists JBIG2 symbol coding and lossy JBIG2 as missing instead of
monochrome JBIG2, with a status line and a revision row.

JBIG2 images, and JBIG2 stencil masks, were reported as "can't be exported
yet", so an image the Optimizer stores as JBIG2 would stop exporting. They
are now decoded with hayro-jbig2 (already in the tree through hayro), with
their /JBIG2Globals from a DecodeParms dictionary or array, as JBIG2Decode
gives them: black as 0 (ISO 32000-2 §7.4.7). Unreadable globals, a JBIG2
page of another width, or fewer rows than the image skip the image; rows
past its height are dropped, so the output is bounded by the checked size.
docs/pdf-spec-parity.md §7.4 no longer says there is no JBIG2 encoding.

pdfcraft_filters::encode_jbig2_generic writes 1-bit rows as a JBIG2
stream for JBIG2Decode (embedded organisation: a page information
segment and an immediate lossless generic region, no globals): template
0 with its nominal AT pixels, typical prediction, and the MQ arithmetic
coder (mq.rs), written from the JBIG committee's ISO/IEC 14492 Final
Committee Draft. The coder reproduces its Annex H.2 test sequence byte
for byte; output round-trips through hayro-jbig2, and Poppler renders
it the same as the original.
The optimizer's Monochrome Images gets JBIG2 (lossless) beside CCITT
Group 4 (still the default), doc_optimize mono jbig2; a document below
PDF 1.4 gets /Version /1.4 in its catalog. On 300 dpi text JBIG2 is
about a third smaller than Group 4.

- Not only Export ▸ Images refuses a CCITT image until #4335: so does
everything that exports an image through it. Save Image As refuses
it, Copy Image fails, and Word, PowerPoint and HTML export leave the
picture out, with the page not reported. The optimize README and the
mono-compression parity note name them.
- optimize.mono-compression is partial now, so docs/target-app-parity.md
counts it on the table's own measurement: K Optimize and standards 15
shipped and 11 partial of 58 (35.3%), breadth 57.0% (423 + 75 of 808),
mainstream 63.3% (292 + 45 of 497), with a status line and a revision
row. ROADMAP.md's breadth rows and its K row say the same.

- Redaction doesn't decode CCITT, so a mark over part of an image the
optimizer stored as Group 4 removes the whole image (nothing leaks),
and Export ▸ Images refuses it. The optimize README and the
mono-compression parity note say so. Later PRs of this stack add both
(#4335 export, #4384 redaction).
- doc_reduce's description, Engine::reduced_bytes and docs/cli-batch.md
now list the black-and-white step; docs/target-app-parity.md's
optimize row gives the measured counts and no longer lists CCITT as
missing; the M11 milestone row lists it as done.

pdfcraft_filters::encode_g4 encodes packed 1-bit rows as Group 4 (ITU-T
T.6, /K -1) through the fax crate (MIT, already in the tree via tiff),
with rows capped at 32,767 samples so its 16-bit positions can't
overflow; round trips are checked against hayro-ccitt.
The optimizer (Settings::mono, CCITT G4 by default, so Reduce File Size
too) re-encodes a 1-bit image of one colour component, or an image
mask, stored with no filter or general-purpose ones, when that is
smaller as stored. The samples decode to the same bits, so colour
space, decode array and masks stay. PDF Optimizer gets a Monochrome
Images row and doc_optimize a mono option. optimize.mono-compression
goes from planned to partial (JBIG2 and monochrome downsampling not
yet).

* M3: give the kept button release back before the pointer leaves (Wayland)
After a desktop grab the next input on Wayland often brings only
PointerGone. The synthetic release went after it, and a button event
sets egui's pointer position, so the gone pointer came back and hover
stuck at the old place until the pointer moved. The release now goes
before the first PointerGone as well as before the first press; a
release that follows PointerGone is still the kept one and not doubled.

Report generators draw each picture as `q re W n cm Do Q` inside a clip the section shares with
its text. `image_transform_scope` only accepted a scope that contained every active clip, which
none does there, so it fell back to transforming the `Do` alone: the picture grew, but its own
clip stayed at the old size and the enlarged picture showed only through its old box.
When no scope contains every clip, the outermost scope holding only the image is used: it holds
all of the image's private clips, which now move with it, while the outer clip, shared with
other content, stays where it is. A clip shared with a caption inside the same scope still stays
fixed (`cropped_image_resizing_moves_private_clips_and_keeps_shared_ones`). Crop uses the same
scope, so cropping such a picture replaces its own clip instead of nesting a second one.

* M4: Document Properties has a Custom tab for custom properties
Document Properties has a new Custom tab between Fonts and Advanced. It
lists the document's custom properties, and Name and Value fields with
Add, Update and Delete edit the list. Clicking a listed property fills
the fields with it. OK writes the changes through SetInfo in the
existing "Change document properties" step, so one undo reverts them
with the other tabs' changes.
Add is off for an empty value, a name already listed, a name that
check_custom_key refuses (its message is the button's tooltip), and a
name the file already uses for an entry the list leaves out (not text,
only padding, or past the 256 listed). A property already in the file
under a refused name or a name that is not UTF-8 is listed, and Add,
Update and Delete stay off for it, so OK cannot fail on it or write a
different key.
Clearing an /Info entry now removes it when /Info is a dictionary
written directly in the trailer. set_info_entry returned without a
change there, so a delete in the Custom tab, a cleared Description field
and a doc_set_info clear left the entry in the file. It now writes a
copy without the entry as a new indirect /Info.
The engine re-exports check_custom_key and adds Document::has_info
(organize::has_info). set_option("dialog", "custom") opens the tab.
* Contributors: add dotCooCoo (Robert Lee)
* M4: Add in the Custom tab stops at the 256 properties the tab lists
Document Properties > Custom lists at most 256 properties, so a property
added past that was saved but left out of the list when the dialog opened
again. Add is now off once the tab's list or the file's own list holds 256;
a new name goes after the file's entries, so a file with more than 256 keeps
Add off after a Delete as well.
With only --automation-read-root / --automation-write-root set, a path
went straight to std::fs::canonicalize, so a UNC, WebDAV or device path
(`\host\share\x.pdf`, `\.\pipe\x`) was resolved, contacting the host,
before it was refused. `--root` mode already refuses those by name
(`foreign_share`).
`foreign_share` moves into file_access, and `AutomationRoots::check_path`
applies it to the path made absolute (by name, nothing read) before
following links, with the same refusal as any other path outside the
root. A root on a share still accepts that share. `resolve` is split
into `absolute` (empty path, device names, made absolute) and `resolve`
(links followed), so `out\NUL` keeps its own refusal.
Part of #4003 (the first of its three points).
main's #4284 stopped hashing translation catalogues in ATTRIBUTION.toml; the
conflict took main's side (no sha256 lines) and kept this branch's source notes.
Conflicts: docs/roadmap.md: all status lines kept, M10 row from main, M11 row with #3227's two sentences. parity/acrobat-features.toml: save-with-object-streams entry from #3227 with its test paths under tests/it/.
Conflicts:
- ATTRIBUTION.toml: fi.tsv source: main's text plus the PR's added sentence; the PR's sha256 line dropped (translation catalogs carry none on main).
- ATTRIBUTION.md: main's rows, fi row updated to the same source text.
ROADMAP.md, docs/roadmap.md: kept both sides' status and progress-log lines; did not restore the older M14 status line that the branch had already trimmed.
Conflicts: ROADMAP.md, docs/roadmap.md: both sides' status, progress and change-log lines; M10 row has the soft-mask sentence added to ours, M11 row from the earlier merge.
Conflicts: ROADMAP.md, docs/roadmap.md: both sides' status, progress and change-log lines; M10 row has both sentences. parity/acrobat-features.toml: export.docx evidence has both tests, notes has both statements.
Conflicts: ROADMAP.md and docs/roadmap.md took both sides' status lines, progress-log and change-log rows; M10 table row from #4311, M11 row from #4310.
Edit::PasteContent pastes an added text box or image copied in the same
document or another, as it was (a text box's style; an image's picture,
turns, flips and crop), as one undo step. A pasted image draws its picture
from the copied object while that is still the picture in the target, else
from an added image there that already holds it (an earlier paste from
another document), else the file is embedded. Document::added_image_file
gives a copied image's picture as a file and honours the copy permission.
pdfcraft_edit::added::paste_rect / paste_place place a paste where the item
was, 18 pt down and to the right past each copy of it on the page (an image
with the same box and transforms counts whichever object holds its
picture), or at a point, kept on the page.
The content_copy tool drives it headlessly, across pages and documents.
The desktop keys and menus come in follow-up PRs.

* Assets: translation catalogs aren't hashed
The 33 UI translation catalogs are project files under the project
licence, and git history records their provenance. Their ATTRIBUTION.toml
entries keep title, author, source and licence but carry no sha256, so a
PR that changes UI text no longer has to edit ATTRIBUTION.toml.
cargo xtask assets accepts a kind = "translation" entry for a .tsv under
crates/ui-egui/src/i18n/ without a hash, rejects one that has a hash, and
still requires a hash for every other entry.
* Assets: a leftover hash on a translation catalog is a note, not an error
Delete the translation coverage tests and the tests of one language's
wording. Keep catalog validation (format, duplicates, placeholders, plural
forms, command ids) and the tests that use a language (registration,
plural rules, RTL order, glyphs, casing, font fallback).
cargo xtask i18n-report runs i18n::tests::translation_gaps_report, which
prints each language's missing count and first few keys and always
passes; xtask ci runs it after the tests.
* CI speed: line tables for workspace crates, no debug info for dependencies
* CI speed: xtask ci runs nextest and doctests, one wasm check, the CLI without default features
