Follow-up to #1420.
#1420 compares the bytes of each entry to tell a file added twice from a
different file with the same name and size. An image or text file is
converted to PDF each time it is added, with its own date, so those bytes
never match and the same .txt or image added twice was no longer flagged.
Each entry now keeps the file as it was added (the same bytes for a PDF,
the image or text otherwise), and that is what is compared.
Adds the_same_image_or_text_file_added_twice_is_a_duplicate in
combine_ui.rs, which fails before this change.
Some programs start the PDF reader with the path unquoted
(`pdfcraft.exe P:\Archive\00042A26 Contract.PDF`), so Windows splits it
into `P:\Archive\00042A26` and `Contract.PDF` and neither opens
("Couldn't read 00042A26: os error 2"). Acrobat accepts this. Rejoin
consecutive arguments when one names no file but it and the ones after it,
joined with a space, do (longest run first); everything else is kept as
given. Done before the single-instance hand-off, so files sent to a running
PdfCraft are rejoined too.

ui.move refuses a coordinate that isn't finite once narrowed to a
pointer position; ui.click {x, y} and ui.drag did not, so 1e39 became
an infinite position and was queued. With debug assertions on, the
next idle frame panicked in emath comparing NaN vectors.
Both now refuse such a coordinate with an error, as ui.move does, and
ui.drag also refuses ends too far apart for the way between them to
stay finite.
Adds click_and_drag_refuse_coordinates_that_overflow_like_move in
tests/control.rs, which panics before this change.
Rules skipped in the accessibility results were kept in one set for
the whole app, and every check applied it. With the options dialog
turned off, skipping Tagged PDF in one document made the next
document's check report it as Skipped, its findings cleared, in the
panel and the saved report.
The set is now keyed by document: Skip Rule records the rule for the
document whose report is shown, and a check applies only that
document's skips. Start Checking in the options dialog still starts
over, for the document it checks only.
Adds a_rule_skipped_in_one_document_is_not_skipped_in_another in
tests/accessibility.rs, which fails before this change.
Use a session-wide byte-accounted LRU instead of retaining every visited
page. Share the renderer's PageText Arc without cloning all glyphs and
avoid retaining obsolete document bytes through the cache.
Preserve per-page extraction results so text_find can continue after a
failed page, reporting bounded warnings alongside readable matches and
normal continuation cursors. Other text consumers retain strict errors.
Add deterministic coverage for cache budgets across documents, eviction,
revision changes, close, partial searches and bounded warnings.
Fixes#1483.

`set_info` changed only `/Info`. Files that carry XMP (LibreOffice and Word
exports, PDF/A) kept the old dc:title and dc:creator, so viewers that read
XMP first kept showing the old title, and PDF/A preflight reported the two
as different (6.6.3).
The matching XMP property (Title dc:title, Author dc:creator, Subject
dc:description, Keywords pdf:Keywords, Creator xmp:CreatorTool, Producer
pdf:Producer) is now replaced where it stands, added in a description of
its own, or removed with an empty value. The packet is edited as text and
the rest of it stays byte for byte; files without XMP get none, and a
packet that isn't UTF-8 is left as it was.

Follow-up to #1259. Before a connection authenticates, the control server
read request lines with BufRead::lines, which buffers a whole line before
anything looks at it, so a client that never sends `auth` could make it
buffer an arbitrarily long line.
Read lines with a bounded read instead. Until `auth` succeeds a line may be
at most MAX_AUTH_LINE (4 KiB; the auth request is about a hundred bytes);
a longer one gets a -32600 error and the connection is closed, after
reading at most MAX_AUTH_LINE + 1 bytes of it. After `auth`, lines are read
whole as before. End of stream, read errors and non-UTF-8 input end the
connection as they did with BufRead::lines.
Tests: lines_are_read_up_to_the_limit, an_overlong_line_before_auth_is_refused,
long_lines_after_auth_are_still_read.

* M8: redaction unlinks removed images and forms from inherited and shared resources
Apply Redactions and Remove Hidden Information give a rewritten page its own
pruned /Resources, but the dictionary the page drew through before could still
name the image or form that was removed:
- a /Resources inherited from a /Pages node;
- one resource dictionary object shared by several pages;
- the page's own dictionary, when a form without /Resources drew the image
through it.
A full-rewrite save keeps whatever is still referenced, so the removed image
samples and form text stayed in the saved file while the operation reported
success. Per-page resources (the case fixed in #1099) were not affected.
The interpreter now records the original object behind every XObject it drops
or replaces. After the page loop, each page-tree resource dictionary that still
names one loses that entry unless a page drawing through that dictionary still
draws the name (the same image on another page, or again outside a mark). A
dictionary that loses an entry is replaced by a private copy on its node, so a
dictionary object shared with other nodes is left alone for them. If a page's
use of a name cannot be told (unreadable content, a form that will not decode),
the operation fails closed.
Tests: redacted_xobjects_do_not_survive_through_inherited_or_shared_resources,
an_image_another_page_still_draws_through_the_same_resources_is_kept,
an_image_a_form_drew_through_the_pages_resources_does_not_survive,
a_hidden_layers_image_does_not_survive_through_inherited_resources.
Not covered here: originals named by a form XObject's own /Resources, by an
annotation appearance or by a pattern.

* M9: a cross-reference entry the reader sets aside is never an unchanged signed object
The reader that judges post-signing changes and the renderer that draws the
page resolve some cross-reference entries differently. A revision appended
after signing could redefine a page's content stream and give the object an
entry the reader sets aside while the renderer follows it:
- an in-use entry at offset 0 (the reader skips it; the renderer fails to read
the object there, rebuilds its index and takes the last definition);
- a second entry for the same object in one section (the reader keeps the
first, the renderer the last).
The classifier compared the signed object with itself, found nothing changed
and reported the signature Valid while the page showed the new content.
pdfcraft-cos now records the entries it does not take at face value
(Document::xref_oddities: offset-0 in-use entries other than object 0,
duplicate entries that differ, reserved cross-reference stream types, and a
hybrid /XRefStm entry that disagrees with the table), and can say whether an
entry locates the object itself (Document::xref_entry_is_exact). What it
resolves is unchanged.
classify_changes treats any such entry added after the signed revision as a
change that is never permitted (page content when the object was a signed page
or its content, other changes otherwise). An object whose content compares
equal at a new place is unchanged only when its entry is exact: where the
reader had to search for the object, another reader may arrive elsewhere.
Tests: a_cross_reference_entry_the_reader_sets_aside_does_not_hide_new_page_content,
a_cross_reference_entry_that_misses_its_object_is_not_an_unchanged_object,
cross_reference_entries_that_are_set_aside_are_recorded,
an_entry_that_misses_its_object_is_found_by_searching_but_is_not_exact.
This closes the two demonstrated triggers and their near variants. It does not
prove that the two parsers agree on every file: other differences in what each
tolerates may remain.

* M8: Apply Redactions is refused when the page still shows text under a mark
Redaction decides what lies under a mark from the positions its own
interpreter computes, and its verify pass reuses them. Where those differ from
the renderer's, a mark drawn over the text as displayed lies over glyphs the
interpreter places elsewhere, or does not see at all: they stayed in the file
and the operation reported success.
The case the test pins: a font and size set through an ExtGState /Font entry
(`gs`), which the renderer honours and the interpreter does not model. The same
kind of gap was observed for a font a form XObject takes from its caller, for
some predefined CMaps and for a rotated Type 3 font matrix. The standard-14
width error that first showed it is fixed at its root by d0d1ad81.
The engine now asks the renderer, which is what the user saw when placing the
marks. After redaction runs, the result is written as a save would write it
(without the marks' own overlay), its text is extracted, and a glyph still at
least half inside a mark fails the edit with the existing "could not be
verified" error. The edit runs on a copy, so the document is unchanged. A page
whose text cannot be read back fails the same way.
This makes such mismatches fail closed; it does not make those documents
redactable. Teaching the interpreter each of them is separate work.
Test: redaction_is_refused_when_the_page_still_shows_text_under_a_mark (the
line whose font is set by `gs` is refused and left unchanged; the same line set
with `Tf` is redacted).

wgpu validates indirect draw and dispatch arguments with a compute shader it
compiles when the device is created. Metal on an Intel Iris Pro (MacBookPro11,3,
macOS 12.7.6) fails to compile it ("Compiler encountered an internal error" in
MTLCompilerService), the device is lost, and the window falls back to OpenGL.
PdfCraft draws and dispatches nothing indirectly, so leave the check out of the
instance flags. WGPU_VALIDATION_INDIRECT_CALL=1 turns it back on. VectorCraft
does the same (storytold/vectorcraft#651).

On macOS sync_all is F_FULLFSYNC, which SMB and FUSE volumes such as a mounted Cryptomator vault refuse with ENOTSUP or ENOTTY, so every save there failed. Those two errors now fall back to fsync; any other flush error still fails the save.
* fix(edit): move existing text by its frame, and selections with the arrow keys (fixes#1520)
* docs(parity): arrow-key nudging and the paragraph frame are no longer gaps (#1520)
Two follow-ups the maintainer asked for after #1355.
The script session's worker now says when the engine is ready for the
script it was sent (its JavaScript context built; FormCalc at once),
and the script's time limit runs from then, with the engine's own
start limit before it, as the one-shot path always did: building a
context is not charged to the script, which matters on a busy machine.
A field inside an area shares its data node with a field of the same
name outside it (areas are left out of data paths). The in-place
refresh of the live form now follows the data path through the tree
and gives every field bound to the node the value the tree builder
would, each by its own template field (an exclusion group there means
a rebuild), and the engine's value setter, with an index of widgets by
data node, gives every widget bound to the node the value by its own
kind, hidden fields included, writing the data whenever the node's
text differs. The script's time now also starts after its host and
globals are set up. A stale parity note (choosing a picture for an
image field, delivered in #1175) is removed.
The launcher installs and updates PdfCraft with `msiexec /passive` and no properties, so
INSTALLDESKTOPSHORTCUT always took its default of 1 and every update put the shortcut back,
even for users who had deleted it. The property no longer has a static default: a SetProperty
after AppSearch turns it on for a first install, and for an update only while PdfCraft.lnk is
still on the all-users desktop. A value on the command line still wins, and the full-UI
checkbox still starts ticked on a first install.
test-msi.ps1 checks the action runs after AppSearch in both sequences and evaluates its
condition for first installs, updates with and without the shortcut, and
INSTALLDESKTOPSHORTCUT=0.
A build compiled with PDFCRAFT_BUILD_LABEL=<label> shows "0.7.1 (<label>)"
in `pdfcraft --version`, `pdfcraft-cli --version`, Help > About and the
first log line (pdfcraft_engine::build_info). The version itself is
unchanged, so the update check, the MCP server info and the User-Agent
still carry the release version.
packaging/linux/package.sh puts the label in the file names
(pdfcraft-0.7.1-<label>-linux-x86_64.rpm) and makes the .rpm/.deb release
`1.<label>` (nfpm `release: ${RELEASE}`, 1 when unlabelled). rpm sorts
0.7.1-1.<label> after 0.7.1-1 and before 0.7.2-1, so a locally built
package upgrades over the installed release and the next release replaces
it. packaging/env.sh accepts only letters, digits and inner dots, which
are valid in both rpm and deb release fields.
Unlabelled builds are unchanged.

* M8: Retire inherited redaction resources
* Redaction: pin inherited resources only on redacted pages, shared by reference
localize_resources rewrote every page in the document on every apply and copied a direct
inherited /Resources dictionary into each one, so a large document grew by N x the dict.
Now only redacted pages that inherit resources are pinned; a direct inherited dictionary is
made one indirect object and shared by reference. The parent's /Resources is retired when no
other page still inherits it (the leak fix), and kept (through the shared reference) when an
unredacted page still draws with it. A /Parent chain that can't be followed or disagrees with
the page tree retires nothing. Tests: an unredacted page is left untouched and the rewrite is
bounded; redacting every inheriting page retires the parent's resources. ROADMAP entry moved
into the revision-history table.

Rebase onto 7163ba3 (396 commits on). Three adaptations, none of them
behavioural:
- `crates/fonts` renamed its `arabic` module to `shaping` and added
Thai, so `Family::width`'s callers moved; the italic argument is
re-applied to all six, including one new call site main added in
`draw_laid_shaped`.
- `Metrics::text_of` now returns `Cow<str>`, so the F2 tests compare
through `as_deref()`.
- `unicode_map` writes into a struct field now, so `/Differences`
inserts go to `out.encoding`.
`SMALL_ITEM_FINGERPRINT` in added/arabic_tests.rs is re-pinned, and this
is the part worth reviewing. That golden is the appearance-stream pin
F1's acceptance criteria asked for, which landed from the Arabic work
after F1 was written; it caught the change correctly. The item's Latin
run is "Hi " in Helvetica 12pt. The old character-class guess called H
680, i 260 and space 260 (14.4pt); the published metrics are 722, 222
and 278 (14.664pt), verified against the table. The Arabic clusters that
follow start 0.264pt further right, which is the intended effect: the
glyphs now land where the font says they do. The Arabic path itself is
untouched.
Also dropped from the rebase: a re-added ATTRIBUTION entry for
vendor/hayro-interpret/assets/LAB.icc, which main deleted in favour of
CGATS001Compat-v2-micro.icc. Carrying it would have attributed a file
that no longer exists.

Two gaps in code-to-Unicode, both found by probing the current
behaviour rather than by reading the code.
A font with no /Widths and no /ToUnicode fell back to StandardEncoding
whatever it was, so /Symbol code 0x61 -- `alpha` in Symbol's own
built-in encoding -- decoded as "a". ZapfDingbats and MacExpert were
read as Latin the same way. That map is what `redact` matches patterns
against, so a wrong character there is a silent redaction failure, and
a wrong character is worse than no character. Symbol, ZapfDingbats and
MacExpert now yield no mapping at all unless the font names a base
encoding, which is always honoured as the deliberate statement it is.
This keys on the base font *name*, not the /FontDescriptor symbolic
flag. A great many ordinary Latin TrueType subsets set that flag and
still rely on a Latin encoding, so suppressing on the flag would lose
real text across a large share of real documents. A test pins that
restraint so it is not "fixed" into a regression later.
Glyph names now follow the published naming algorithm instead of two
of its cases: a name is cut at its first `.` (`a.sc` is `a`), split on
`_` into components (`f_i` is "fi"), and `uniXXXX` carries any number
of four-digit values (`uni00660069` is "fi"). Names are resolved whole
or not at all, so half a ligature is never returned. `glyph_text`
returns a String for this; `glyph_unicode` stays as the single-character
view. Hex parsing rejects the leading `+` that `from_str_radix` would
otherwise accept, and a lone surrogate half.
Both halves were verified by reverting each fix and watching the
matching tests fail. The parity note on protect.redact-patterns now
says Symbol-encoded text is skipped rather than mis-decoded.
Still open, and an owner decision: Symbol and ZapfDingbats could be
mapped properly with a glyph-name-to-Unicode table, but the vendored
Adobe Glyph List is not on the AGENTS.md 1.1 closed list.

`Family::width` chose its standard-14 face from `bold` alone and passed
`italic: false`, while `Family::base_font` writes the item out as the
italic or oblique face. Every italic item was therefore laid out with
upright metrics: Times-Italic `A` is 611 against Times-Roman's 722, so
boxes, wrapping and centring were all sized from the wrong face.
The measure now takes `italic` and the five call sites pass the item's
own flag, which they already had in scope. The test walks all twelve
style combinations and asserts the written face and the measured face
are the same one, so the two can't drift apart again.

Isolated so it can be reverted on its own.
AGENTS.md 1.1 keeps a closed list of Adobe-authored non-visual technical data,
and adding to it needs the owner's explicit approval, which was given on
2026-10-08. The item itself -- the standard-14 font metrics and encoding tables
from the PDF specification -- was already on that list; what is new is holding
a copy first-party rather than only through hayro, which is what lets generated
appearances measure with it and what survives hayro being retired in M2.8.
The gate only understood the list for dependency-bundled files, and rejected
adobe_data on a repository file outright. It now accepts it for a closed list
of first-party paths, so crates/fonts/src/std14.rs carries an ATTRIBUTION entry
with its SHA-256: regenerating the table fails the gate until the entry is
updated, which makes a change to Adobe-derived data a deliberate act rather
than an ordinary edit.
Worth noting that .rs is not an asset extension, so the table would never have
been scanned at all. Entering it on the list is a choice to be checked, not a
requirement the gate imposed.

pdfcraft_fonts::helvetica_width was a fifteen-line guess by character class,
and seven crates generated appearance streams through it: annot, edit, forms,
ocr, redact, sign and xfa. Times was Helvetica x 0.9, bold was x 1.05, Courier
a flat 0.6. Against the published metrics a Times capital A is 722, so that
estimate said 600 -- a 17% error on a letter, compounding across a line.
Std14 carries the real advance widths for all fourteen faces, indexed by
character code: WinAnsiEncoding for the twelve text fonts, which is what we
write into the appearance streams we generate, and their own built-in
encodings for Symbol and ZapfDingbats. The tables are generated by joining the
published encodings with the per-glyph widths.
helvetica_width now delegates, so every call site gained exact Helvetica with
no change. The three places that faked another face by scaling it -- Family
in edit::added, the paragraph measure in edit::text, and the redaction overlay
fonts -- now select the right face instead. So does Metrics::width in
fonts::pdf, which measures existing document text when a font carries no
/Widths; that path feeds redaction's glyph removal, where a wrong width means
cutting the wrong glyphs.
Tests spot-check the table against values typed in from the specification by
hand, so it is verified against the spec rather than against whatever produced
it; plus Courier being fixed pitch everywhere, full printable-ASCII and Latin-1
coverage, Symbol and ZapfDingbats not being WinAnsi, /BaseFont aliases and
subset prefixes resolving, and hostile text staying finite.

Replaces this PR's earlier contents. It previously added a committed
`docs/plan/` tree -- a status baseline, an architecture doc and an
execution plan. Since then `main` has grown `docs/gaps.md`,
`docs/target-app-parity.md`, `docs/roadmap.md` and `docs/architecture.md`,
which are actively maintained (gaps.md was reviewed 2026-10-10 and
updated 2026-10-11) and cover the same ground better, because they sit in
the flow contributors already touch. Keeping a parallel plan would have
meant two sources of truth and a document that rots; it had already gone
conflicting twice in three days. So the plan is dropped and only the
parts with no equivalent anywhere remain.
`.github/pull_request_template.md` is new -- the repository had none,
with 167 PRs open and 66 of them conflicting. It leads with the two
things a contributor cannot be expected to know and that cannot be undone
after a merge: provenance (no Adobe asset, no committed font, no copied
GPL/AGPL code, behaviour from the spec rather than from reading another
implementation) and the never-crash rules. It also asks for a test that
has been *seen to fail* before the fix, and says plainly that per-crate
verification is preferred because CI runs the workspace anyway.
CLAUDE.md gains three things it did not record: the four-zoom review
habit (clause, function, file, project) with the tests that mirror it;
the external-PR bar; and a note that builds and tests should be scoped
per crate, because a full workspace build has locked up a development
machine and CI covers it. The commit rule now also says that `main` moves
fast enough for PRs to rot -- 396 commits in three days -- and that
conflict risk tracks how contested the files are rather than how large
the change is.
