The earlier notes cited an observation made on a public real-world form,
which the Privacy rule does not allow. Re-observed in Acrobat Pro on
synthetic forms (three breakBefore pageArea sections, then a page area with
occur min=1 max=1, with and without relevant="-print"):
- the once-only page comes last in both;
- when printing it is kept in both, blank only with relevant="-print";
- a breakBefore on the first section, with or without startNew, makes
Acrobat open an empty body page first (5 pages); with no break on the
first section it lays out 4, as PdfCraft does. Recorded as a gap.

* M10: Office export reads forms as far as the renderer and says where it stops (#3120)
Export to Word, PowerPoint, HTML and RTF stopped at 12 nested forms and
4 096 forms a page and left the rest out silently. It now follows forms
50 deep, as the renderer does, and up to 50 000 a page (the renderer's
budget for nested paints), still bounded on hostile files.
doc_export_office lists pages past those limits in truncated_pages, with
a warning. New: reading_blocks_checked and export_office_checked;
reading_blocks and export_office keep their signatures.
Fixes#3120

* Tests: pin the form depth limit to the renderer's 50 (#3120)
The depth test built its chain from MAX_FORM_DEPTH, so it moved with the
constant. Write the renderer's limit out: depth 50 is read, depth 51 is
left out and reported. Fails with the constant at 49 and at 51.

* Export: say which forms count toward the page limit (#3120)
The page budget also counts forms the page draws itself, which the
renderer does not charge, so a page can be reported as cut although the
viewer shows it. The warning and the tool description now say so.

* M6: a date typed without separators fills a yyyymmdd field
parse_date read each run of digits as one number, so 20261018 in a
yyyymmdd field was a single number with nothing left for the month and
the day, and the keystroke check refused it. Every date field on forms
that use the YYYYMMDD date format (US Army forms such as DA Form 31 among
them) refused every valid date.
order() now records each field's fixed width (4 for yyyy; 2 for yy, mm,
dd, HH, MM and ss) and whether the next field follows with nothing in
between. parse_date keeps runs of digits as text and splits a run between
such joined fields by those widths. Formats with separators, month names,
literal digits (dd.mm.26) and two-digit years behave as before.
A run of digits too long for a u32 used to be dropped silently, which let
"2026 99999999999" pass for yyyy; it is now read like any other number and
refused when it is left over or does not fit.
* chore(contributors): credit Eric Kaden by real name
* M6: separated runs of digits stay whole in a joined date format
With separators each run of digits is one field's number, as before this
branch: "2026-10-18" in a yymmdd field reads the year 2026, where the
first commit split the run into 20 and 26 and refused the date. A run is
now split between joined fields only when fewer runs were typed than the
fields still to fill, so "2610" and "261018" still split.
* M6: what is left of a split run of digits fills its field exactly
"202610018" in a yyyymmdd field split off 2026 and 10 and read the rest,
018, as day 18, so a nine-digit date passed. The rest of a split run now
has to be its field's width; a number typed on its own ("2026 10 018")
keeps its leeway.
* M6: a number typed on its own is split only when its rest fills the next field
The optional time fields of a format like yyyymmddHHMM counted as fields
still to fill, so "2026 10 018" split the day 018 into 01 and 8 and was
refused; on main the time defaults to 00:00. A run typed on its own is
now split only when what is left can fill the next field; the rest of a
run that was already split is split as before.
* M6: describe the undelimited-date tests without naming one form
The tests and their comments now say what they check (fields written side by side, such as yyyymmdd) instead of naming the form that showed the problem, and use a generic field label.
* M6: count date and time fields apart when deciding to split a run
Optional time fields counted towards the fields still to fill, so
"2026-10-18" in a yymmddHHMM field split the year into 20 and 26 and was
refused, where main reads it with the time left out. A run typed on its
own is now matched against the fields of its own kind: date runs against
date fields, time runs against time fields. What is left of a split run
goes on being split along the fields written side by side, so
"20261018143005" still fills yyyymmddHHMMss. A mix such as
"2026 1018 1430" (year apart, month and day joined, then a time) is still
refused, as on main.

The calendar took its month once, when it opened, so a date typed while
it was open showed only after leaving the field and coming back. It now
moves to a date as soon as the text becomes one, and stays on the month
it shows while the text is half typed or unchanged, so its arrows still
turn the months.

* M2: a JP2 image in a colour space the decoder refuses is drawn by its component count (#3306)
The veraPDF fixture's JPX header names CIEJab (enumerated colour space 19),

When the decoder refuses the image and its colr boxes name such a space, it is

hayro-syntax and pdfcraft-cos took the stream data to start at the space, so the

Review on #3356: under a skew, a direction between the axes stretches
further than either axis, so the larger axis stretch could place a miter

* fix(app): a launch without SESSIONNAME hands its files to the console session's window (#3338)

* fix(windows): name the single-instance socket by the session id, not SESSIONNAME (#3338)
Review on #3340 (earlvanze): falling back to the console's socket when
SESSIONNAME is unset could hand a file from a Remote Desktop session to a
console window of the same user in another session. The socket is now named
by the session id in the process token (winsafe, no unsafe): a launch from
Task Scheduler runs in the user's session and finds its window, and
different sessions never share a socket. SESSIONNAME names it only if the id
can't be read.
Tested with a real scheduled task: on main the task's launch (no
SESSIONNAME, session 1) opened a second window; with this change the file
went to the running window in session 1.

* M7: work out each font's space width once per paragraph rewrite (#2616)
Each keystroke in Edit text rebuilds the paragraph's draft. When a source
font can't show a space (LaTeX and Sphinx subsets space words with TJ
kerning instead), source_space reads every font on the page, building
Metrics for each. The draft did that once per character, so a keystroke
in a 380-character paragraph of NVIDIA's vGPU guide took ~460 ms. The
widths are now worked out once per font before the per-character pass:
~71 ms there, ~16 ms for a 200-character paragraph (was ~255 ms), with
identical layouts.

Recovery snapshots are unsaved copies of open documents. The folder was
made with the default mode, so on a shared Linux or macOS machine other
accounts could list it and read the snapshots of documents that are not
encrypted. The folder is now made owner-only (0o700), and a folder an
earlier version made is tightened when an instance starts or writes a
snapshot, as image_pick does for its folder. A volume that can't change
modes (FAT, some network shares) works as before, with one warning in
the log.
Merges left four hayro-interpret rows; the current one lacked the
transparency-group, Type 3 rendering-mode and Lab white-point patches (each
numbered 25, 27 or 28 on a branch where another patch took that number).

* M10: exported TIFF and JPEG pages record the resolution they were drawn at
A page exported as TIFF said 1 x 1 with no unit, whatever the dpi, and
a JPEG export said nothing, so other programs showed and printed them at
a default (a 300-dpi page shown at 72 dpi is four times too big).
encode_image now takes the dpi: TIFF X/YResolution in inches, the JFIF
density in dots per inch.
PNG stays without pHYs. It counts pixels per metre, so 72 dpi would read
back as 72.009, and a page made from an exported PNG (doc_create from
images, as enhance_camera_image_through_tools does) would come out 0.01%
small.
Exporter records the resolution a page was actually drawn at (dpi_used),
so a page too large for the renderer says the lower one. render records
--dpi, since it refuses oversized pages. The TIFF is written with the
tiff crate, already in the graph, because image's TiffEncoder can't set
a resolution.
* M10: TIFF page exports are LZW-compressed, as documented
encode_tiff's comment said "LZW-compressed by the encoder's default",
but the TIFF was written uncompressed: a Letter page at 300 dpi came to
25 MB. It is now LZW without a predictor, the compression TIFF readers
support most widely after none.
* Contributors: add my name for the About window
* cli: info names the standard a document declares
A PDF/A file was summarised with no mention of PDF/A. `info` prints two dozen
fields -- tagged, xfa, javascript, layers -- and said nothing about the
standard, while the app's Standards panel reads the same declaration from the
catalog's XMP and shows "PDF/A-2b" (#3319).
`info` gains `pdfa` (the part and conformance together, e.g. "2B"), `pdfua` and
`output_intents`, from `pdfcraft_preflight::declared` -- the call the Standards
panel makes, so the two agree by construction rather than by a second reading
of the metadata. A document that declares nothing leaves them null and empty.
Read in the CLI rather than in `pdfcraft_render::Inspect`: render is layer 3
and preflight layer 4, so the summary struct can't reach it, while an app may
depend on any layer.
* cli: read the declaration from the bytes already in hand
`Document::open_with_password` takes an `Arc<Vec<u8>>` and `info` already holds
one, so `bytes.to_vec()` copied the whole file for every call -- a file-sized
allocation on a large PDF, for nothing. Clone the `Arc` instead.
* info: name the declared PDF/A level as the automation tools do (PDF/A-2b)

* M4: Ctrl-drag copies pages in the Organize grid (#2997)
Dragging thumbnails in the Organize page grid with Ctrl held (Option on
macOS) drops copies at the gap instead of moving the pages: a "+" badge
by the pointer, the copies land at the gap selected, and one undo step
takes them out. The insertion point joins the engine edit
(Edit::DuplicatePages { at }) so the copy is one undo step rather than a
duplicate plus a move.
page_duplicate takes a 1-based "at" (the first copy becomes page "at"),
so agents can drive the same thing, and the UI control channel's
ui.drag modifiers now reach the input state -- which gestures that read
it (this copy-drag, and Alt-drag column select) need.
Closes#2997.
* fix(ui): take the grid's copy modifier from the runtime OS (#3092 review)
Option-drag in the Organize grid moved the pages instead of copying them in a Mac
browser: `cfg!(target_os = "macos")` is false in the wasm build, and eframe sets the
context's OS from the browser. `copy_modifier` now takes the context and asks
`commands::mac_shortcuts`, as the shortcut labels do.
The drag helpers in `tests/editing.rs` and `tests/control.rs` picked the modifier the
same compile-time way, so they would have sent Ctrl on a Mac host; both read the
context's OS now. The new regression test
`option_copies_and_ctrl_moves_when_the_context_reports_macos` drives a Mac context —
Ctrl moves, Option copies — and fails without this change.
tags::clean, which drops /Alt, /ActualText and /E that repeat redacted
text, walked the structure tree from the root's /K only, so an element
listed only in /ParentTree or /IDTree kept the redacted words. It now
starts from both trees too, as drop_object_refs does since 3f543ca1.
Past its 2,000,000-reference cap the walk used to skip the rest and
report success. It now fails closed: every structure element in the
document, found by reading each object rather than through the tree,
loses its alternate and actual text.

also starts from both trees and follows their nodes (/Nums, /Names,
/Kids), written in place or as their own objects.
