Brandon ThomasandClaude Opus 5.5 73fdb261ef UI: share the Japanese fallback font with printcraft-fonts (one 8.7 MB copy, not two)
The UI theme include_bytes!'d ShipporiMincho-Regular.ttf, which
printcraft-fonts already embeds as SHIPPORI_MINCHO for Japanese text in
PDFs, so the app carried two copies. ui-egui now depends on printcraft-fonts
(layer 2, wasm-clean) and uses its static. The desktop app binary drops from
85.8 MB to 77.5 MB (debug build; one copy of the font left, counted).

Brandon ThomasandClaude Opus 5.5 7b85af8785 Tests: full screen and the About dialog get their own tests (parity evidence)
Both were marked shipped on the generic 'every registered command is
implemented' test, which the honest assessment flagged. Full screen: the
shortcut enters, Escape leaves, and the command toggles both ways. About:
the dialog shows the running version.

Brandon ThomasandClaude Opus 5.5 20842c72e3 Never crash: Type 1 font programs can't hang or overflow the stack (skrifa 0.47)
The nightly fuzz job found a Type 1 font that hung hayro: read-fonts 0.39
(through skrifa 0.42) looked ahead after every integer by parsing the next
token, which looked ahead again, recursing through a whole run of numbers.
A long run hung; 20,000 numbers overflowed the stack and aborted the
process. Upstream fixed the tokenizer; the vendored hayro-interpret now uses
skrifa 0.47 (read-fonts 0.44), with its one API change. The finding finishes
in 0.5 s. Synthetic regression test (it aborts with the old skrifa).
Corpus sweep: 0 regressions; text oracle unchanged (median F1 0.980, mean
0.866, every per-file score identical).

Brandon ThomasandClaude Opus 5.5 6e90710e4b Never crash: JBIG2 images can't decode billions of pixels
The nightly fuzz job found a JBIG2 symbol dictionary that decoded for
minutes: each bitmap side may be 65535, and up to 65535 symbols are decoded
pixel by pixel. Vendored hayro-jbig2 0.3.0 with two bounds: at most 2^28
pixels per bitmap (also the page bitmap, halftone grid and grayscale image),
and at most 2^26 symbol pixels per dictionary. The finding now finishes in
about a second. Synthetic regression test (a 65535 x 65535 page and region
behind a small /Width and /Height); the corpus sweep shows 0 regressions.

e59c9a793e Fix text editing layout and preserve source PDF font styles (#36)
* Comments: a text box's rectangle follows its edited text

Editing a text box (or typewriter or callout) rewrote /Contents but
kept the old /Rect: the appearance clipped the new text to the old box
and silently dropped lines that no longer fit, while shorter text left
an oversized box. set_contents now re-measures the text with the same
Helvetica widths as at creation and re-fits the box: the wrap width and
top edge stay, the height fits the wrapped lines. A callout's leader
line keeps its place and re-attaches to the moved box (that geometry
moved from set_rect into a shared apply_text_box). A locked box keeps
its text editable, so it re-fits too.

Covered by annot tests (grow and shrink with nothing clipped, callout
leader re-attach, locked box) and a comment_edit round trip through the
automation tools; parity entries cite them.

Brandon ThomasandClaude Opus 5.5 2f364665b8 Never crash: the fuzz job's eleven hangs finish (parser retries, inline images, Type 3 fan-out)
Every hang the nightly fuzz job found (11 findings, 8 source files) now
finishes in 0.1-2 s; each cause has a synthetic regression test that times
out without its fix.
- cos (7 findings, our own parser): a stream whose /Length pointed at
  itself, with no endstream, made every parse attempt fail and each attempt
  reload the same object: ~2^32 parses. Objects being loaded are a seen-set,
  /Length values are memoised per load, and the shifted-header retry only
  runs when the header is shifted.
- hayro-syntax (3): deciding where an inline image's data ends re-parsed the
  rest of the stream, nesting through every inline image; 50 images ran for
  over ten minutes. The look-ahead no longer nests and is bounded (256).
- hayro-interpret (1): a Type 3 glyph showing eight glyphs of its own font,
  sixteen deep. Nested paints share a per-page budget (50,000).
The pdf.js corpus sweep matches its baseline (963 ok, same 20 known).
xtask check writes its report under CARGO_TARGET_DIR too.

Brandon ThomasandClaude Opus 5.5 de9b9e82bc Updates: check only when asked (no check at start)
By the owner's decision there is no update check at start and no in-place
install for the foreseeable future. The startup option, its setting and the
first-frame trigger are gone; Help ▸ Check for updates is the only request.
Settings written by a build that had the option are ignored.

Brandon ThomasandClaude Opus 5.5 85a8652de1 Issue #28: Help ▸ Check for updates, with an opt-in check at start
PrintCraft asks GitHub for the latest release and, when it is newer, offers
its release page to download from. Nothing is downloaded or installed
automatically (installing in place needs signed release artifacts).

- ui-egui: updates module (version comparison, background check, dialog);
  no network code: the desktop app supplies the source, and without one
  (web build, tests) the command opens the releases page.
- desktop: one HTTPS request (ureq over rustls with the OS's trusted roots,
  10 s timeout, 1 MiB cap). Only a page under the releases list is offered.
  No bundled root list: webpki-roots/webpki-root-certs are CDLA-licensed.
- The check at start is opt-in and silent unless there is a newer version.

Brandon ThomasandClaude Opus 5.5 27f7ef96fe Issue #8: prefer the integrated GPU, and the save prompt answers to the keyboard
- On hybrid-graphics laptops wgpu picked the discrete GPU (egui-wgpu defaults
  to HighPerformance). NVIDIA's can lose or corrupt its memory across suspend
  and screen lock, which matches the illegible window in #8. PrintCraft now
  asks for the low-power adapter unless WGPU_POWER_PREF is set; one-GPU
  machines are unaffected, and it saves battery.
- "Save changes?" had no keyboard: Enter saves, Escape cancels, and Don't save
  takes Cmd/Ctrl+D (macOS) or Alt+D / Alt+N (the mnemonics the reporter tried).
  Its keys are read before the canvas (which took Escape), and no other
  shortcut runs underneath it (Cmd+D opened Document properties).

Brandon ThomasandClaude Opus 5.5 a5d830bf25 Never crash: predictor rows and stroke widths from the input can't exhaust memory
The second full nightly fuzz run on main found two more:
- hayro-syntax computed a Flate/LZW predictor row as columns × bits in
  wrapping arithmetic: /Columns 9223372036854775807 asked for 2^61 bytes and
  aborted on any machine. Row widths are now saturating usize (colors × bits
  also overflowed u8), a zero width is refused (it divided by zero), and a
  row longer than the data is not allocated (empty output, as before).
- hayro stroked /LW 9223372036854775807 as given, and stroke expansion
  allocated 10 GB. Widths are clamped to 4 × (canvas width + height) device
  pixels, which covers the same pixels.
Both findings now run in 8 MB. Synthetic regression test in render.

Brandon ThomasandClaude Opus 5.5 6058068266 Never crash: absurd image-mask and CCITT sizes are refused before decoding
The first full nightly fuzz run on main (now that the runner survives) found
two 4 GiB allocations, caught by the 4 GiB child cap:
- an inline stencil mask claiming /W 4294967295 was decoded in hayro-interpret
  before the renderer's MAX_IMAGE_PIXELS check could skip it (locally 9.6 GB,
  42 s). Vendored patch image_size_ok: images and masks over 2^28 pixels are
  not decoded.
- a CCITT image whose /DecodeParms claimed /Columns 4294967295 (with a small
  /Width) sized the decoder's line buffers (locally 4.3 GB). Vendored patch
  ccitt_size_ok in hayro-syntax: at most 2^20 columns and 2^28 pixels.
Both findings now run in 7 MB. Synthetic regression test in render.

Brandon ThomasandClaude Opus 5.5 1449b71a19 Never crash: bound the allocations behind the nightly fuzz runner's out-of-memory deaths
Fuzzed inputs drove one check-one process to 2-6 GB (the 16 GB CI runner
running two of them was killed every night). Three causes, each with a test:
- lopdf (bootstrap inspector) sized PNG predictor rows from /Columns before
  reading data: /Columns 4294967295 allocated two 4 GiB rows. Vendored lopdf
  0.45.0 refuses rows longer than the data (and uses saturating row widths);
  its load-time stream decoding also gets a 256 MiB limit (it had none).
- hayro sized a tiling pattern's cell pixmap from /XStep x scale, bounded only
  by u16: a step far beyond /BBox allocated 2 GB. The vendored patch keeps
  the cell within 3000 px a side, lowering the resolution instead.
- cos decoded cross-reference streams up to the general 1 GiB limit; they now
  stop at what 8,388,607 objects' rows can hold (~200 MB at most), and the
  section is reconstructed (logged) instead.

On the nightly's seed (41) the worst captured input fell from 6.2 GB to 6 MB,
and a 300 s fuzz run had no process above 300 MB (before: many at 2-5 GB).

Brandon ThomasandClaude Opus 5.5 9ecfd0afbc Tests: frame budgets take turns and keep the best of three rounds
The two budget tests ran in parallel, each with its own render workers, and
a single preempted stretch on a shared CI runner pushed the average over the
40 ms budget (41-52 ms on Ubuntu and Windows). They now hold a lock while
measuring, and a round over budget is measured again (up to three rounds):
noise only adds time, so the best round is the UI's own cost and a real
regression still fails every round. The budget is unchanged.

Brandon ThomasandClaude Opus 5.5 ac222e818b Never crash: edit and xfdf have no expect calls

  Paragraph grouping uses `let … else` / `if let` chains, and the reuse-font path takes the
  metrics with `filter` instead of `expect("checked")`.
- xfdf: a comment key that vanished between listing and lookup is skipped.

Both crates now deny the panic lints. Adds the root clippy.toml (identical to #11) so tests may
still unwrap.

e7ba974fe1 Edit text: a rewritten paragraph keeps its place in the text object it shares (#7)
* Edit text: a rewritten paragraph keeps its place in the text object it shares

A rewritten paragraph was drawn again just before the BT of its text object. When earlier
paragraphs shared that BT … ET (as in text-only pages), the paragraph moved ahead of them in
the content: reading order changed (screen readers, copy, `pdftotext -raw`) and text_paragraphs
renumbered, so after text_edit paragraph 2 a following text_edit paragraph 1 rewrote the
already edited paragraph instead of the first one. The text object is now split where the
paragraph was, and the second half resumes from the same line matrix and text state.

95af23d3a5 Forms: multi-select list values survive XML, CSV and text import (#5)
Export data writes a multi-select list's values into one cell joined by ", " ("A, C"), but
import passed the cell on as a single choice, which the list refused, so the selection was
silently lost on an export → import round trip (the field was only counted as rejected).
A multi-select list now splits such a cell into its options, unless the whole cell is itself
one of them.

24f0a8928e Edit text: a paragraph's new colour no longer spills into the text after it (#6)
Rewriting a paragraph (text_edit, Format text) draws it in its own text object, then sets the
text state back for what follows, but not the fill colour. Changing one paragraph's colour
therefore also coloured every paragraph after it in the same content stream (recolour the
first paragraph of a page red and the rest of the page turns red). The rewritten paragraph is
now wrapped in q … Q, so its colour and other graphics state stay with it.

096b515719 Forms: CSV import keeps values that span lines (#4)
* Forms: CSV import keeps values that span lines

A quoted CSV value may hold line breaks, and export_data writes multiline text fields that
way. The importer split the file into lines before reading quotes, so such a value was cut
at its first line break and every later column was lost (an export, then an import, of a form
with a multiline field silently dropped data). CSV records now end only at unquoted line
breaks; tab-delimited text is read as before.

Content added with Edit ▸ Add content records its image in the content stream's dictionary
(/PCAdded /Image). The audit claimed a page's content streams before its resources and
followed that reference, so an added image's bytes were reported as Content Streams and
Images showed 0 % (a 1.9 MB picture read as 99.9 % content). Resources are now claimed
first, so whatever a content stream's dictionary points at keeps its own category.

- `Session::open`, `save_bytes`, `save_full_bytes` and `export_data` report a panic as an
  open, write or export error.
- `PrintCraftApp::execute`: a command that panics shows a notice, and the app and its documents
  keep running.
- The desktop app installs a panic hook that logs every panic to stderr, with a backtrace when
  `RUST_BACKTRACE` is set.

Brandon ThomasandClaude Opus 5.5 18c1acdb31 Never crash: hostile form scripts can't overflow the stack
boa's parser and compiler recurse once per nesting level and have no limit of their own: about
100 nested parentheses in a field or document script overflowed a 2 MiB stack and aborted the
app, which `catch_unwind` can't stop. `printcraft_js::run` now:
- refuses a script longer than 256 KiB, or one that nests brackets more than 64 deep, chains
  more than 64 prefix operators, or has more than 4096 `?`. Strings and comments are skipped.
  The script fails with an error, as a syntax error would;
- runs the engine on its own thread with a 1 GiB stack, which is address space, committed only
  as it's used. That covers every unbracketed construct a 256 KiB script can nest. A panic
  inside the engine becomes a script error. On wasm the script still runs inline.

Regression tests: `deeply_nested_scripts_fail_instead_of_crashing`, which aborted the test
process before this change, and `ordinary_nesting_still_runs`.

Brandon ThomasandClaude Opus 5.5 58cd6614ea Never crash: engine denies the panic lints
The one `unreachable!` in the scoped refresh becomes a full refresh.

Brandon ThomasandClaude Opus 5.5 9fc3354fe6 Never crash: filters, fonts, js, optimize and a11y deny the panic lints
- js: `host()` returns a script error instead of panicking when the host state is missing.
- optimize, a11y: the graphics-state stack is read with `last`/`last_mut` instead of `expect`.
- fonts: the standard-14 ASCII map is built from `u8`, which can't fail.
- filters: zlib encoding into a `Vec` keeps the standard's narrow, documented `expect` exception.

Brandon ThomasandClaude Opus 5.5 95d8ba3101 Never crash: crypt has no panic paths
AES blocks come from `as_chunks`, the IV from `split_first_chunk`, and the R6 hash takes its
AES key and IV with `first_chunk`, so no `expect` is needed. The crate now denies the panic lints.

Brandon ThomasandClaude Opus 5.5 15f6fa7d4c Never crash: forms scripts can't overflow the stack or the date arithmetic
Two crashes that a PDF can trigger, each with a regression test that failed before this change:
- Deeply nested arguments in a field's format script (`[[[[…` or `new Array(new Array(…`) and
  deeply nested simplified field notation (`((((…` or `----…1`) recursed until the stack
  overflowed, which aborts the whole app. Nesting is now capped at 64 levels; deeper input is
  rejected like any other unparseable script.
- A date with a huge year (`1/1/2147483647`) overflowed `weekday`, and a `DateTime` with month 0
  indexed before the month names. The weekday math is now done in i64, years beyond i32 don't
  parse, and month and day names are looked up with `get`.

Also removes the crate's remaining `expect`/`unreachable!` calls and denies the panic lints.

Brandon ThomasandClaude Opus 5.5 ab47bf4b9a CI: as_chunks instead of constant-size chunks_exact (clippy 1.99 chunks_exact_to_as_chunks)
Stable clippy 1.99 denies chunks_exact/chunks_exact_mut with a constant
size (32 sites), which failed the test job on main and every open PR.
Behaviour unchanged; MSRV 1.90 has as_chunks.
