   - See `plan/README.md` §Clean-room and `plan/adr/0001`.
 - **Privacy.** When observing Acrobat, use synthetic fixtures only. Never capture the Home view, recent files or account info. Capture by window id (`plan/acrobat/tools/`). Never commit Acrobat outputs, corpus files or personal data.
 - **Layering.** Nothing below L7 depends on egui/winit/eframe/rfd (`plan/architecture.md` §3). `cos`/`filters`/`crypt`/`arlington` stay standalone.
+- **Page input.** Page modules read `PagePointer` (`crates/ui-egui/src/page_pointer.rs`), never egui's raw pointer state (`hover_pos`, `interact_pos`, `latest_pos`, `press_origin`, button reads); `page_pointer::tests::page_modules_read_the_pointer_only_through_page_pointer` enforces it.
 - **Fidelity.** The PDF object graph is the model. Preserve unknown data. Saves are incremental unless a full rewrite is required. Never silently drop or repair data without recording it.
 - **Never panic.** Every PDF, script, MCP call, settings file and keystroke is untrusted input, and none of it may crash the app or lose the user's work. This outranks feature work. Return `Result` (the crate's error enum) and propagate with `?`, or fall back leniently and record it. In non-test code:
   - No `unwrap`/`expect`/`panic!`/`unreachable!`/`todo!` unless it is provably infallible, with a comment saying why.

-`ui.dock` arranges the `tools` and `inspector` panels; `canvas` is the protected document view.
-Each per-panel request requires a `panel` ID and an `operation`: `open`, `close`,
-`activate`, `float` with `rect: [x, y, width, height]`, or `move` with `target` and
-`zone: center|left|right|top|bottom`. For example,
-`{"operation":"float","panel":"tools","rect":[100,100,320,440]}` floats Tools.
-`ui.dock.reset` restores the default
-arrangement. The control channel accepts these methods directly; `ui.command` also accepts
-`{"id":"ui.dock","params":{...}}`. Saved preferences retain groups, active tabs, visibility
-and floating geometry. Invalid requests return an error without changing the document or layout.
+`ui.panel` opens, closes or sizes a side panel: `{"panel":"tools"|"side","open":true|false,"width":320}`.
+`tools` is the Tools panel and `side` the panel the rail opens (reopening it shows the one open last).
+`width` is clamped to the panel's limits (Tools 240–520, side panel 260–520 points). `ui.dock.reset`
+resets the side panels: Tools open on the left, default widths. The control channel accepts these
+methods directly; `ui.command` also accepts `{"id":"ui.panel","params":{...}}`. Saved preferences keep
+the Tools side, the open panels and their widths. Invalid requests return an error without changing
+the document or the panels.
 
 
 `resize` requests a native inner-window size in logical points (each dimension must be between 320 and 8192); the window manager may constrain it. `state` reports the observed `window.width`, `window.height` and `window.pixels_per_point`. `focus` accepts exactly one widget `id` or unique enabled, focusable `label`; subsequent `key` requests traverse or activate the actual widgets. `inspect` includes focusability and accepts a `focused` filter. `quit` takes no parameters: clean documents exit normally, while unsaved edits or typing open the existing Save/Don't save/Cancel prompt and return `quitting: false, needs_confirmation: true`. It never silently discards work. Window resizing and application quit are native-only.

-Tools and Inspector panels can be dragged into tab groups, split beside the PDF, or floated within the app window. Read and full-screen modes keep their existing focused document view. Drag a panel header to a target edge or another header. Its context menu offers Float panel, Move to group, and Close panel. Existing panel toggles reopen panels at their saved location; Reset Panel Layout restores the app layout. Floating panels remain inside the current app window.
-
-Advanced `ui.dock` operations use the same validated transaction as pointer gestures:
-`moveFloating` updates `rect`, `resizeSplit` accepts a boolean child `path` and
-`size` (`{"Ratio":0.5}`, `{"FixedFirst":280}`, or `{"FixedSecond":280}`),
-`setStackOpen` takes `open`, and `resizeStack` takes a point `height` or null.
-A center `move` can include `before` (panel ID or null to append) for tab order.
-The equivalent `{"action": ...}` form accepts a serialized shared docking action;
-this is also the form emitted by the renderer. Protected-canvas and app-specific panel
-rules apply equally to both forms.
+The Tools panel sits on the left, or on the right with Preferences ▸ Tools panel side. The rail stays at the right edge and opens one side panel beside it. Drag a panel's inner edge to resize it; widths are remembered. F4 shows or hides the side panel and Shift+F4 the Tools panel (also in the View menu); View ▸ Reset side panels restores the default arrangement.

 ## Progress log
+
+- **2026-10-24 (M10, #4158 partial):** Word, HTML, RTF and PowerPoint export keep a block that continues another on its line (an italic case name, a link, a superscript) as a run in its own style inside that paragraph, with the source's word space, instead of a paragraph of its own. Style changes that wrap onto the next line still split paragraphs (the reading blocks keep style boundaries). Estimates unchanged.
+- **2026-10-24 (M3, window move on Wayland, #3970 follow-up):** After a move or resize by PdfCraft's own title bar or edges, the button release given back to egui goes before the pointer leaving the window, so hover no longer sticks at the old place until the pointer moves. Found by CodeRabbit in review of #3970; a unit test covers it. Estimates unchanged.
+- **2026-10-24 (M14, #4253):** The annotation quick bar remembers Keep tool selected across restarts, including unpinning. Old and malformed settings keep safe defaults; the opt-in UI control channel reads and changes the same preference. Estimates unchanged.
+
+- **2026-10-23 (M7, #4280):** Edit text names each standard stand-in font after its face (`PCEdTimesBold`, ...) instead of one shared `PCEdHelv`. Rewriting a bold paragraph whose subset lacks an accent no longer repoints the paragraphs set earlier in a regular stand-in at Times-Bold, and the editor's frame stays on the paragraph being edited. Pages saved by older builds keep their shared name and are not repaired. Estimates unchanged.
+- **2026-10-23 (M8, #3205 follow-up):** Phone-pattern redaction matches complete labelled Italian geographic numbers such as `Tel. +39 0426/123456`, with synthetic matcher and mark/apply/save/reopen coverage; unlabelled international slash numbers remain unsupported.
+- **2026-10-23 (M7, #2636 partial):** A new `PasteContent` edit pastes an added text box or image copied in the same document or another, keeping its style, picture, turns, flips and crop, as one undo step; `content_copy` drives it headlessly. A paste lands beside earlier copies (18 pt steps) and stays on the page. A pasted image reuses its picture object in its own document and after the first paste into another; there a colour profile is dropped and CMYK colours stored losslessly are turned to RGB. The desktop keys and menus follow in separate PRs. Estimates unchanged.
+- **2026-10-23 (M11, optimizer resolution):** Image downsampling includes each page's `/UserUnit` scale, preserving images already below the physical resolution threshold, including shared nested forms.
+  Synthetic measurement and optimization regressions cover direct and indirect units and page-local defaults.
+  Estimates unchanged.
+- **2026-10-23 (M10, Word table widths):** Word export sizes each cell from the grid columns it spans, keeping unequal columns and cells after a merged cell consistent with the table grid.
+- **2026-10-23 (M10, table continuation text):** Office exporters retain text from table slots covered by another cell's span as paragraph text.
+  Synthetic regressions check every input fragment survives exactly once in Word, HTML, RTF and PowerPoint, while ordinary superscripts stay in their table cells.
+- **2026-10-23 (M10, image export):** Soft-mask Decode intervals preserve partial opacity in Export all images and Save Image As.
+  Synthetic regressions cover direct and indirect ranges, inverted/subrange alpha, packed masks, JPEG masks and unchanged image component Decode.
+- **2026-10-23 (M10, print resources):** Vector printing preserves original page artwork when existing XObjects use annotation resource names.
+  The regression checks two distinct appearances, inherited resources, print/reopen pixels and unchanged source data.
+  Estimates unchanged.
+- **2026-10-21 (M3, window resize and move on Wayland):** With PdfCraft's own title bar on GNOME/Wayland, a second resize by a window edge, or a second move by the empty tab strip, works straight after the first; it waited for a click inside the window, because the compositor keeps the button's release from egui. A unit test covers the release given back; checked by hand in a test build. Estimates unchanged.
+- **2026-10-22 (M4, #3916 partial):** Document edits and Undo/Redo cancel an Organize page drag. Pointer-release regressions check exact page order and save/reopen.
+- **2026-10-22 (M10, #3752 paper):** CUPS jobs ask for the chosen paper in every size. The 13 sizes the Print dialog sent no paper for (A6, A0–A2, ARCH, ANSI C–E) use PWG 5101.1 names, checked against a synthetic PPD with `cupsfilter`, and `doc_print` to a printer sends the paper too. The macOS tray half (Auto Select instead of the PPD's default tray) is a craft-print change that needs a pin bump here. Estimates unchanged.
+- **2026-10-22 (M14, macOS association recovery candidate):** Successful desktop open/save/sign can queue recovery of an existing per-file binding to the running PDFCraft bundle through NSWorkspace. Metadata-only watcher changes retain undo and avoid false overwrite prompts; real same-length/same-mtime edits remain protected. Rebased on 0.12.0 and reuses #3042's shared atomic metadata preservation; the bounded recovery parser does not narrow save limits. Prior native Preview TEST-signature and Finder workflows passed on macOS 27.0.1; other versions remain unqualified. Estimates unchanged.
 - **2026-10-13 (M7, free image rotation):** A selected page image has a rotate knob (Shift: 15 degree steps) and `image_edit` a `rotate_by` action; the angle is written as one undoable `cm`. Snapping to page edges while moving is in #1740; resize snapping is not done. Estimates unchanged.
 
 - **2026-10-20 (M4, initial view):** Window and interface options read indirect boolean ViewerPreferences values. Synthetic regressions cover true/false, direct/indirect preference dictionaries and save/reopen; malformed entries retain false defaults. Estimates unchanged.
 - **2026-10-20 (M3, #3535):** Escape with a menu open closes the menu and keeps the text selection; the next Escape clears it, as before. One keypress used to do both. A synthetic UI regression checks it. Estimates unchanged.
 - **2026-10-16 (M3, close prompt keyboard):** The "Save changes?" prompt opens with Save chosen (Enter saves, as before) and the arrow keys and Tab / Shift+Tab move the choice to Cancel or Don't save, shown with a focus ring; Enter or Space press the chosen button and Escape still cancels. Before, Enter always saved whatever was Tab-focused. Estimates unchanged.
 - **2026-10-21 (M3, #3808):** Page thumbnails in the Inspector can be resized independently from the document and Organize, with a slider, buttons and `thumbnail-zoom` control option. Selection, page following and reload are covered by regressions. Estimates unchanged.
+- **2026-10-22 (M5, comment threads):** Replies join the comment their `/IRT` references, not every comment sharing its `/NM`; PyMuPDF names each page's first comment `fitz-A0`, so all replies used to land under page 1. The Comments header counts comments without their replies, with the number of replies in small text under it (in every catalogue), and a reply's thread line runs from the avatar above it to its own. A reply to a reply shows in its thread in the panel too (it was listed nowhere), an `/IRT` that leads to no comment (itself, a loop, a pop-up, an unlisted object) leaves its annotation a comment of its own instead of hiding it (a status or checkmark that leads nowhere is listed nowhere), and a Replace Text caret isn't counted as a reply. The comment tools refuse an `id` several comments share instead of acting on the first (page 1's), and take `page` + `index` for those; `comment_list` reads a status or checkmark from the annotation it was set on, as the panel does, and reports a reply's own on the reply. UI, engine and automation regressions cover it. Estimates unchanged.
 - **2026-10-22 (M2, #3107 / PR #3438):** Inline-image parsing falls back to the existing EI heuristic when missing declared samples, headers or terminators exceed the content-window budget, instead of waiting for an impossible allocation. Exact-length parsing for available samples and ordinary large streamed images is retained. Estimates unchanged.
 - **2026-10-21 (M14, Brazilian Portuguese):** Completed the `pt-br` catalog against the current 2,674-key union, including signature validation and accessibility messages; no build or compilation run. Localization remains partial because help and unpredictable engine/OS error details are not translated.
 - **2026-10-21 (M14, #3557):** Preferences: the OK button stays below the scrolling settings instead of being the last thing in them, so it is in reach in a short window.

 - **2026-10-17 (M8, gap 6, #2662):** A filled cover over a long line counts when it hides half of any one word, not only 40% of the line's words or box, so a black box over one number in a long line — or an unapplied redaction mark over it — no longer audits clean while the number is still extractable; a sliver under half of every word it touches and under 40% of the line is still not flagged
 - **2026-10-13 (M10, #1757):** Office export keeps each dotted-leader contents entry in one paragraph, with its page number, instead of inferring table cells from its separate text objects.
+- **2026-10-22 (M6, calculation scripts):** The Calculate tab and a rename read simplified field notation only from a comment, where Acrobat writes it: a string that spells `BVCALC … EVCALC` is no longer taken for the notation, or rewritten by a rename. A `/` after the condition of `if`, `while`, `for` or `with` starts a regular expression, so a rename no longer rewrites a name inside one, and a quote inside one no longer hides the `getField` calls after it. Both found in review of #3550. A `//` comment ends at `\r`, U+2028 or U+2029 as well as `\n`, so in a script with `\r` line endings the code after one is no longer hidden from a rename, or taken for the notation. Estimates unchanged.

A card says what is wrong with the order and holds Fix order; a loop has a card of its own that opens one of its formulas. On the page, each calculated field shows its step, and arrows show what the field in focus reads and what reads it. Estimates unchanged.
 - **2026-10-20 (M6, calculation order):** The order a form's fields calculate in (`/CO`) is read, checked, fixed and set headlessly with `form_calculation_order`: it says which fields read one calculated later (they show stale values), which read each other in a loop, and which the PDF's order leaves out; Fix order moves only what must move, in one undo step, and the form recalculates. Editing a formula no longer moves its field to the end of the order, and a field the order lists twice calculates once. Estimates unchanged.

 - **2026-10-20 (M14, Spanish catalog gaps):** `es.tsv` gains the 143 `(context, English)` keys the other catalogs carried and it was missing, so Spanish covers the whole bundled key union like Lithuanian and Vietnamese: calendar months and weekdays, the `certificate` context, X.509 key usages, signature-revision and digital-ID lines, password validation, eight plural messages, the combine-from-folder strings, the rendering and stale-file notices and the shortcut-spelled tooltips. Counts in `localization-parity.md` re-measured against the current union (`vi` restated against it for the same reason). Status stays `partial`: no translated help, and OS details stay outside the catalog. Estimates unchanged.

Notes are saved with the NoRotate flag, and the renderer now honours it: the appearance is turned against the page's rotation about the upper-left corner of `/Rect`, which stays put (ISO 32000-2 §12.5.3; vendored hayro-interpret patch 37). Attachment icons follow the same rule. Selection, hover, the edit composer, the Comments panel's flash and the `comment_list` and `doc_info` rectangles use the drawn box, and `comment_add` anchors an icon's displayed top-left at `at`.

An RGB JPEG stored untransformed (`/ColorTransform 0`, no marker) used to be converted from YCbCr anyway and came out in other colours, recompressed or merged from strips; it now keeps them. A JPEG whose marker and `/ColorTransform` disagree, or whose components are named R, G and B without `/ColorTransform 0`, is left as it is, since readers differ on it. Estimates unchanged.
 - **2026-10-15 (M2, gap 12):** `cargo xtask text-oracle` scores reading order as well as word F1: the longest common subsequence of the two word sequences over the longer one. F1 is a bag of words and cannot see order at all -- measuring #2431, a change that moves text and nothing else, it called 26 of the 29 files whose output changed identical, where the order score separated 18 improvements from 6 regressions. Reports, does not gate; a disagreement with Poppler, not a verdict. Estimates unchanged.

Across the pdf.js corpus the soft hyphens we extract fall 117 to 13 and the non-breaking spaces 30 to 26; the rest come from `/ToUnicode`.

A page area's `occur min` is honoured too: one the body never reached gets the pages it still needs after the body (the once-only closing page of a form, with its button, comes last). Acrobat Pro also puts that page last, and when printing keeps it but leaves it blank (`relevant="-print"` on the page area), which PdfCraft does not do yet; both re-observed on a synthetic fixture, see the 2026-10-19 line.

+- **2026-10-12 (M10, Edit on a scanned page):** Turning Edit on (its tab, Edit text & images or Add text) for a scanned page (an image covering at least half of a page with no text of its own; comments and text boxes over it do not count) recognizes the page first, like Acrobat's "Converting scanned page to Editable Text and Images", so its words open for editing. Once per page per window, one undoable "Recognize text" step, with the language of the Recognize Text dialog (English only for now, gap 7). Pages with real text (a flyer with a background picture), read-only files and other tools are left alone. The photographs on a scan are still part of the one page image.
 - **2026-10-13 (M3, typed zoom):** The right rail's zoom percentage is an editable field: type 150, 150% or 62.5 % and press Enter, Escape discards, and nonsense keeps the current zoom. The control channel's zoom option shares its parser, which now refuses zero, negative and non-finite values.
 - **2026-10-13 (M4, indirect page rotation):** Rotation queries and edits resolve indirect integer values on pages and their page-tree ancestors. Turning a page already at 270° by 90° now saves it at 0°, including when its rotation is inherited. Synthetic full/incremental save-and-reopen tests cover nested inheritance, sibling preservation, negative/large angles and invalid-value fallback. Estimates unchanged.
 - **2026-10-14 (M1, Flate fallback):** Raw deflate whose first bytes resemble a zlib header no longer loses a decoding-limit error during fallback. Strict and tolerant filter regressions and a COS stream regression cover refusal at the caller limit and successful decoding within it. No parity status or estimate changes.

 - **2026-10-15 (community, M14, Polish signature panel):** A Polish signature panel listed its details in English: the catalog lacked every signature wording, the changes after signing they name and 34 UI literals. All 101 are translated; `polish_covers_ui_literals` and `polish_says_what_a_signature_says` keep them so. Estimates unchanged.
 - **2026-10-14 (M14, Finnish localization):** Added Finnish as another interface and date language, with a 2,674-entry catalog covering every key of the other bundled catalogs and two-form plurals (partitive after numbers other than 1). Calendar dates use partitive month names (`14. lokakuuta 2026`). Coverage tests check commands/tools, scanned UI literals and bundled catalog keys. AI-assisted; native proofreading pending.
 - **2026-10-14 (M14, Catalan localization):** Added Catalan as another interface and date language, with a 2,592-entry clean-room catalog, one/other plurals and coverage tests for commands, tools, UI literals and every key in the other catalogs. A native Catalan speaker (the contributor) has reviewed the translation. Estimates unchanged.

+- **2026-10-15 (M3, #1248):** A fresh install follows the desktop's appearance: the theme preference defaults to System (dark on a dark desktop, Light where the desktop says nothing); saved settings and `--theme` still win. Dark page rendering is Reading colours, and the page reading themes are #1732.
+- **2026-10-15 (M3, #1767):** Restore last view settings when reopening documents, as Acrobat's preference does: a file opened again shows the page, zoom and page display it was last shown with (remembered for the last 100 files when a tab closes or settings are saved), over the file's own initial view; on by default, Preferences ▸ Documents and view turns it off.
 - **2026-10-13 (M3, native-opening candidate):** Chosen tools survive preparation, conversion and password retries; startup intake waits for pending preparation. Regression tests cover completion, cancellation and document identity. Estimates unchanged.
 - **2026-10-13 (community, M3, #531 touchpad momentum):** On Wayland a two-finger swipe keeps gliding after the fingers lift and slows to a stop, measured from the gesture's last 0.1 s and decaying with a 0.35 s time constant through the #759 1:1 path. Any wheel input, click, key, zoom or edge ends it (fingers resting on the touchpad don't yet: the vendored winit binds no Wayland hold gestures); single-page paging, macOS (which sends its own momentum), the web, and Animation effects Off never glide. Unit tests for the physics and two headless view tests. Estimates unchanged.
 - **2026-10-13 (M3, native-open admission):** Later prepared replies stay queued while a modal or native picker owns the foreground. Picker completion, cancellation and abandonment wake retained opens. Regressions cover recipient ownership, exactly-once admission, source/history preservation and one-shot repaint requests.

 - **2026-10-18 (renderer, hayro patches 19/35):** A mesh shading (types 4–7) is sampled over its own triangles instead of the whole path: a BricsCAD plan with 310 one-triangle `sh` fills took 2 s per 1024 px tile at every zoom (and hit the 20 s watchdog on a busy machine); now about 70 ms, so zooming into dense topology drawings stays fluid.

 - For proportional image signature resizing, use the embedded image layer's width/height ratio rather than a previously stretched annotation rectangle. The GUI preserves this ratio at corners with the opposite corner anchored; edge midpoint handles change only their own axis. `comment_edit` accepts the resulting rectangle.
 - `doc_close` refuses to drop unsaved changes unless `discard_changes: true`. `doc_save` writes atomically, incrementally in place, and in full for a new path. Atomic output writes call `sync_all` on the staging file before replacing the destination. A write or sync error leaves the destination intact, removes staging and leaves the document dirty for retry. A filesystem that does not support syncing returns an error; there is no unsynced fallback. This flushes file contents, but does not guarantee persistence of the parent-directory rename across power loss.
 - With a root set, every read and write path must resolve inside it (symlinks and `..` included). Relative paths resolve inside the root, and `..` is resolved by name before the check. Every path outside the root gets the same refusal (`<path> is outside the allowed directory <root>`), whether or not it exists, so a confined agent can't probe the rest of the disk; on Windows another network share or device path (`\\host\share`, `\\?\UNC\…`, `\\.\…`) is refused without being contacted. "Not found" and other filesystem errors are reported only for paths inside the root. Tools that write several files into a folder name them after the document or input file, with separators, colons and control characters replaced by `_`, so a name can't lead them out of the folder. The root itself must be a folder.

 panics. `redact` and (later) `edit` build their interpreters on it; the graphics-state tracker
 and the `Patch` API of architecture §6 grow here.
 
-Unfiltered inline images with built-in or Indexed colour spaces, and image masks, use their
-sample layout (including per-row byte padding) to locate `EI`. This preserves pixel bytes
-that look like the terminator. Filtered images and resource-defined colour spaces retain
-the tolerant delimiter heuristic; damaged or truncated layouts fall back to it too.
+An inline image ends where the renderer's tokenizer (`hayro-syntax`) ends it, so the parser
+and the renderer read the same operators after the image, and redaction removes what the page
+actually draws. Only where that tokenizer reads no image (its parameters don't read, or no `EI`
+passes its checks) does the parser locate `EI` by its own rules: unfiltered images with built-in
+or Indexed colour spaces, and image masks, by their sample layout (including per-row byte
+padding), other images by the tolerant delimiter heuristic. Such an image is counted in
+`Parsed::ambiguous_images`, because the operators after it may not be the ones the page draws.

+- Image codecs (DCT, JPX, JBIG2, CCITT), `Crypt` and unknown filters anywhere in a chain give `Unsupported`: callers keep such data encoded. So does a chain longer than `MAX_CHAIN` (8) filters, before any stage runs. Decryption belongs to `crypt`.
 - `max_output` bounds every intermediate buffer (including the pre-predictor buffer) and gives `LimitExceeded(max_output)`. This also holds when Flate retries raw deflate after a misleading zlib header, in both strict and tolerant decoding.
+- `decode_counted` and `decode_tolerant_counted` are for a caller charging a budget (`pdfcraft_cos::DecodeBudget`). `max_output` bounds all stages together (each stage gets what the earlier ones left), and they give the bytes every stage that ran decoded, on success and on failure. A stage's output counts as its decoder produced it, before a predictor or a later stage shrinks it, and a failed decode pays for what it decoded first.
 - `decode_tolerant` turns `Corrupt` into "what was decoded so far" plus `partial = true`, then runs the rest of the chain on it (predictors are applied to partial output too). `LimitExceeded` and `Unsupported` are still errors.

 On macOS, `write_atomically_with` copies the existing regular destination's accessible extended attributes to the open staging file after writing the data and before flushing and renaming. Finder tags, comments, binary values and empty attributes therefore survive both incremental and full saves (#2658). Save As retains attributes of an existing destination; a new destination does not inherit metadata from the source PDF. Missing files and filesystems without xattr support keep working. The metadata read does not follow the destination's symlink or block on a FIFO. macOS manages the new file's `com.apple.provenance`; it is not copied. Kernel-hidden compression attributes are not requested.
 
-Attribute copying is bounded: 64 KiB of names, 1024 attributes, 16 MiB per value and 64 MiB total. Each value must fill the initially queried size and retain that size in a second query after reading: a resource fork may return a partial prefix on growth rather than an error. A read/copy error or exceeded bound returns an error suggesting Save As; the original bytes and metadata stay intact and the staging file is removed. Flush errors retain the same guarantee. Tests cover exact metadata before flush and after repeated saves, empty/binary values, oversized resource forks, a simulated partial read of a growing fork and symlink isolation. Automation covers incremental/full saves, Save As and retaining an unsaved edit after metadata refusal. The staging writer also retains Unix permissions and, where supported, Windows/macOS creation dates; attribute copying runs before the creation date is restored. ACLs and hard-link identity are not preserved.

+A phone label such as `Tel.` or `Fax:` also enables Italian international geographic numbers with a slash, such as `Tel. +39 0426/123456` or `Fax: +390426/123456` (#3205 follow-up).
+The country code and national number are matched together, with the significant initial `0` and 6 to 11 national digits described in the [AGCOM numbering plan published by ITU](https://www.itu.int/dms_pub/itu-t/oth/02/02/t020200006b0001pdfe.pdf).
+This narrow case accepts at most one space after `+39` and one slash immediately after the area code; international slash numbers without a phone label, or with country codes other than +39, remain unsupported.
+Patterns are heuristic: dates, protocol identifiers and longer number runs are retained, and users still need to review the marks before applying them.
 
 `codes` holds the redaction code sets (U.S. FOIA and U.S. Privacy Act exemptions):
 `CodeSet::from_id("foia")?.overlay(&["(b)(6)"])` gives the overlay text for the picked codes.

+# Persian (fa) catalog. Columns, separated by a TAB:  context <TAB> source <TAB> translation
+#
+#   context  empty                a plain UI string; `source` is the English text in the code
+#            @id                  a command id (e.g. file.saveAs): wins over the English text for
+#                                 that menu item, so one id can read differently from its twin
+#            @plural              `source` is "one|other" (English forms); the translation lists the
+#                                 language's forms separated by "|" (see `plural` in i18n/mod.rs)

+#   escapes  \n  \t  \\  inside a column. `{name}` placeholders must appear in both columns.
+#   lines starting with # and blank lines are ignored.
+#
+# Clean-room: every entry was written from the plain meaning of the English label using ordinary
+# Persian computing vocabulary. No proprietary localisation resource, string table or product UI
+# (Acrobat's included) was consulted or copied; add entries the same way.
+# Product and technology names (PdfCraft, PDF, Acrobat JavaScript ...) stay in Latin letters.
+#
+# Right to left: like Arabic and Kurdish, entries stay in logical (typing) order.
+# `rtl: true` in i18n/mod.rs selects explicit right-to-left text direction; epaint reorders
+# each rendered line. The Persian comma \u060c and question mark \u061f are used, and \u200c (ZWNJ) joins
+# compound words.

+	The signature uses the legacy adbe.x509.rsa_sha1 format.	امضا از قالب قدیمی adbe.x509.rsa_sha1 استفاده می‌کند.
+	The signature is BER-encoded (indefinite lengths) rather than DER; it was read leniently.	امضا به‌صورت BER رمز‌گذاری شده است (طول‌های نامعین) نه DER؛ با اغماض خوانده شد.

+	The RSA signature value does not have the length of the key's modulus (leading zero bytes dropped or added); it was read anyway.	مقدار امضای RSA طول پیمان‌های کلید را ندارد (بایت‌های صفر ابتدایی حذف یا افزوده شدهاند)؛ به هرحال خوانده شد.
+	The RSA signature's DigestInfo has no NULL parameter (older signers write it so); it was read anyway.	DigestInfo امضای RSA پارامتر NULL ندارد (امضاکنندگان قدیمی‌تر آن را چنین می‌نویسند)؛ به هرحال خوانده شد.

+	The signature algorithm and the SignerInfo's digest algorithm name different hashes; the signature was made with the SignerInfo's.	الگوریتم امضا و الگوریتم چکیدهٔ SignerInfo هش‌های متفاوتی را نام می‌برند؛ امضا با هش SignerInfo ساخته شده است.
+	The signature's signed attributes have no content type, which CMS requires; it was read anyway.	ویژگی‌های امضا‌شدهٔ امضا نوع محتوا ندارند، که CMS آن را الزامی می‌داند؛ بههرحال خوانده شد.
+	This signature uses SHA-1, a weak hash algorithm: collisions in it have been demonstrated. It still validates because many documents signed years ago use it, but it should not be relied on.	این امضا از SHA-1 استفاده می‌کند، یک الگوریتم هش ضعیف: برخورد‌ها در آن به اثبات رسیده است. همچنان معتبر است چون بسیاری از اسناد امضا‌شده سال‌ها پیش از آن استفاده می‌کنند، اما نباید به آن اعتماد کرد.
+	This signature uses RIPEMD-160, a legacy 160-bit hash algorithm that is no longer recommended for signatures. It still validates, but it should not be relied on.	این امضا از RIPEMD-160 استفاده می‌کند، یک الگوریتم هش قدیمی ۱۶۰ بیتی که دیگر برای امضا توصیه نمی‌شود. همچنان معتبر است، اما نباید به آن اعتماد کرد.
+	This signature uses an RSA key shorter than 2048 bits, which is no longer considered strong enough for signatures. It still validates, but it should not be relied on.	این امضا از یک کلید RSA کوتاه‌تر از ۲۰۴۸ بیت استفاده می‌کند که دیگر برای امضا‌ها بهاندازهٔ کافی قوی در نظر گرفته نمی‌شود. همچنان معتبر است، اما نباید به آن اعتماد کرد.
+	The signature's signed attributes have no message digest, so the signature does not cover the document.	ویژگی‌های امضا‌شدهٔ امضا چکیدهٔ پیام ندارند، بنابراین امضا سند را پوشش نمی‌دهد.
+	The signature's signed attributes name a content type other than data, so it is not a signature of the document.	ویژگی‌های امضا‌شدهٔ امضا نوع محتوایی غیر از داده را نام می‌برند، بنابراین امضای سند نیست.
+	The document has been altered or corrupted since the signature was applied.	سند از زمان اعمال امضا تغییر کرده یا خراب شده است.
+	The signer's certificate is not in the signature.	گواهی امضا‌کننده در امضا نیست.

+	The signer's certificate was not valid at the time of signing.	گواهی امضا‌کننده در زمان امضا معتبر نبود.
+	The signer's certificate does not allow digital signatures (its key usage has neither digital signature nor non-repudiation).	گواهی امضا‌کننده امضا‌های دیجیتال را مجاز نمی‌داند (کاربرد کلید آن نه امضای دیجیتال دارد و نه انکارنا‌پذیری).
+	The signer's certificate is not issued for signing documents (its extended key usage has no document-signing purpose).	گواهی امضا‌کننده برای امضای اسناد صادر نشده است (کاربرد کلید گستردهٔ آن هیچ هدف امضای سند ندارد).
+	The signer's certificate has critical extensions PdfCraft does not recognize ({}).	گواهی امضا‌کننده افزونه‌های حیاتی دارد که PdfCraft آن‌ها را نمی‌شناسد ({}).
+	The certificate of {} is not a CA certificate that may issue certificates, so it is not used to vouch for {}.	گواهی {} یک گواهی CA که بتواند گواهی صادر کند نیست، بنابراین برای تأیید {} استفاده نمی‌شود.
+	The certificate of {} has critical extensions PdfCraft does not recognize, so it is not used to vouch for {}.	گواهی {} افزونه‌های حیاتی دارد که PdfCraft آن‌ها را نمی‌شناسد، بنابراین برای تأیید {} استفاده نمی‌شود.
+	The certificate of {} does not allow this many CA certificates below it (path length), so it is not used to vouch for {}.	گواهی {} این تعداد گواهی CA در زیر خود را مجاز نمی‌داند (طول مسیر)، بنابراین برای تأیید {} استفاده نمی‌شود.
+	The certificate of {} was not valid at the time of signing, so it is not used to vouch for {}.	گواهی {} در زمان امضا معتبر نبود، بنابراین برای تأیید {} استفاده نمی‌شود.
+	The signer's identity is unknown because it has not been included in your list of trusted certificates and none of its parent certificates are trusted certificates.	هویت امضا‌کننده ناشناخته است زیرا در فهرست گواهی‌های مورد اعتماد شما گنجانده نشده و هیچیک از گواهی‌های والد آن گواهی مورد اعتماد نیستند.
+	The signer's identity is valid.	هویت امضا‌کننده معتبر است.
+	The signature includes an embedded timestamp.	امضا شامل یک مهر زمانی جا‌سازی‌شده است.

+	The signature's timestamp token does not cover the signature value.	نشانهٔ مهر زمانی امضا مقدار امضا را پوشش نمی‌دهد.
+	The signature's timestamp token could not be verified ({}).	نشانهٔ مهر زمانی امضا تأیید نشد ({}).
+	The embedded timestamp token is valid and its authority is trusted; trusted time is {}.	نشانهٔ مهر زمانی جا‌سازی‌شده معتبر است و مرجع آن مورد اعتماد است؛ زمان مورد اعتماد {} است.
+	The signature carries an unverified timestamp ({}): the timestamp authority is not in your list of trusted certificates, so the signing time claimed by the signer is used instead.	امضا یک مهر زمانی تأیید‌نشده حمل می‌کند ({}): مرجع مهر زمانی در فهرست گواهی‌های مورد اعتماد شما نیست، بنابراین در عوض از زمان امضایی که امضا‌کننده ادعا می‌کند استفاده می‌شود.
+	The signer's certificate has been revoked ({}).	گواهی امضا‌کننده باطل شده است ({}).
+	The document's embedded revocation information shows that the signer's certificate has not been revoked.	اطلاعات ابطال جا‌سازی‌شده در سند نشان می‌دهد که گواهی امضا‌کننده باطل نشده است.

+# Current integration — 2026-10-25
+
+The local integration includes main `d764a8ebca2dc289841b34ea3048f613a9869bbb` and pins craft-ui, craft-quit and craft-print to published `42e30cd5b3f4b114270dd053fccbc33bedc47f68`. The egui, winit and independent craft-docpath pins are unchanged. Its `Cargo.lock` SHA-256 is `3e0c10576c8584eb1f45a27908177e7c65bb83f8e855bf3a5429edd4e7268c80`.
+
+Main replaced the floating docking workspace with fixed shared side panes in `crates/ui-egui/src/side_panels.rs`. `PaneHost` owns the Tools and inspector columns; `Rail` owns the fixed navigation rail and footer. The integration retains the 0.37 ID, text alignment, capture, IME and accessibility adaptations. The former `docking.rs`, `rail-nav` panel and read-mode inspector panel no longer exist. Floating windows, tab groups and drag/redock operations from the earlier design are not capabilities of this integrated UI. Their historical acceptance items below do not establish current behavior.
+
+Focused scroll, zoom and RTL palette regressions passed. Removing the production fixes while retaining the tests reproduced double scrolling, double zooming and failed reordered-word RTL search; both source files were then restored byte-for-byte. Independent source review accepted the integration. Full combined-tree CI and the separate web WASM check passed with required external oracles: 5,190 passing test executions, zero failures and 22 ignored across 89 summaries. The first attempt stopped at the storage reservation guard; the successful rerun used an increased reservation. The 5,190 result comes from managed run `egui037-pdf-combined-ci-20261025-1340` and qualifies the integration of main `d764a8ebca2dc289841b34ea3048f613a9869bbb` with `Cargo.lock` SHA-256 `3e0c10576c8584eb1f45a27908177e7c65bb83f8e855bf3a5429edd4e7268c80`, published as `fbfad2039c650a02b39ceee5c3f0e4d6fd4b3f74`. The older 5,183-pass result covered commit `9032aeb35f7abe7777f66d4b835fd461a865c516`, integrating main `71b47b51`; it is a separate checkpoint and is not evidence for the current tree. Both runs recorded 22 ignored executions across 89 summaries.
+
+Remaining acceptance includes native/browser GUI, native IME, packaging and paired performance. Shared-pane F6 cycling and explicit RTL edge mirroring are not enabled. New side-pane command labels still need catalog translations; English fallback remains. Current panel checks must exercise Tools/inspector visibility, Read mode, resizing and persistence, rail selection, F4/Shift+F4, capture and accessible Pane/Splitter labels, rather than the removed floating/tab-group workflows.

+Status update (2026-10-25): Move PdfCraft to the pinned egui 0.37 and winit forks, preserving main `418ac6a2`, including suppression of page link hover while dragging a panel, page-pointer ownership, editor gestures and navigation/security fixes. Adapt UI lifecycle, capture and IME reset handling while preserving logical RTL text. Restore document-properties filename alignment and connect Initial View controls to their accessible labels. Validation: all ten CI stages and the separate web-shell WASM check passed. Focused pointer regressions plus CI recorded 5,130 passing test executions, zero failures and 28 ignored across 143 summaries. The dragged-panel link regression passes on egui 0.37; independent review accepted preservation of the upstream fix. The alignment and accessible-name regressions failed before their fixes and pass afterward; independent reviews accepted the integration and both fixes. Pins and lockfile remain unchanged. Native/browser GUI, native IME, paired app performance and final platform/package acceptance remain open. Human review and human merge are required.

The 2026-10-25 qualification section below supersedes the historical external-config and missing-IME statements; the 2026-10-24 amendment records the earlier local state. The manifests pin egui `6d518fc799681571963842f95b55a6b68431b15a`, winit `a517b3846ee8457d84ee4975110bfda6797c44dc`, and craft-ui/craft-quit/craft-print `25da1314d443171b4adeaad2cd9454b273f35c6f` directly by immutable git revision, while `craft-docpath` remains at `82a24b006eefa036b43c09a67fb9a3fbd17ffe63`; `Cargo.lock` is `f5cee0acb795240d2071116230316fd4e4b6bfe4e4314c82b0a4ca5459739f80`, and the target-main observation is `a7801dc84e74dd12757aecbb6be324dce7a33939`. The repository quality gates passed as recorded below; publication still requires fresh human approval. This revision also incorporates the independent adversarial review of the prior plan (`f781bf52d03d59cd2fb4539771c7a0d196e2f49e64c48635e72c224c9bdcdcd0`).

+## Historical qualification state — 2026-10-25
+
+The managed run `egui037-pdfcraft-reviewed-ui-ci-20261025-0541` passed the first nine CI stages, including formatting, strict lint, workspace tests, WASM compilation, assets and dependency checks. It recorded 5,025 passing test executions, zero failures and 16 ignored across 198 summaries (including four focused regression executions). The final parity stage found one stale test reference after the Arabic logical-order test was renamed; the reference was corrected without changing executable source. Formatting and parity then passed in `egui037-pdfcraft-parity-final-20261025-0555`. An intervening submission `0553` was refused by the storage guard before execution and is not validation evidence. Final documentation/attribution corrections were checked by formatting, assets generation/validation and parity in `egui037-pdfcraft-final-doc-assets-20261025-0571`.
+
+The page-text editor keeps the prior four-by-two inset under egui 0.37, and print tests locate the Two-sided control by ComboBox role. Both narrow/wide text image regressions and booklet regressions passed before the full suite. Canonical dependency/source guards retain the vendored security and rendering provenance. The repository WASM gate checks the library layers. The separate web application shell also passed `cargo check --locked --target wasm32-unknown-unknown -p pdfcraft-web` in `egui037-pdfcraft-web-shell-check-20261025-0575`. Native GUI and IME/PRIMARY, browser interaction, packaged WASM size, real-world old settings and paired app performance remain open; these checks do not establish cross-platform acceptance.
+
+This section supersedes every historical statement below that the egui, winit or
+craft-libs revisions resolve through `local-integration-config.toml`, that the
+checked-in manifest does not pin them, or that E21b/P7b surrounding-text support is
+absent from the candidate. Those statements are planning-era history; the current

+- Native: `apps/pdfcraft/src/main.rs::main` calls `eframe::run_native`; `app_creator` (`main.rs:365`) builds `PdfCraftApp` and wires storage, control, recovery and GPU state.
+- Web: `apps/pdfcraft-web/src/main.rs::main` uses `eframe::WebRunner::start` with `WebOptions { renderer: Glow }`, `?file=`, `?host=parent` and the before-unload warning.
+- Headless: `crates/ui-egui/examples/shot.rs` uses `egui_kittest::Harness::build_eframe` plus `Harness::render`; `apps/pdfcraft-cli` has no egui/eframe dependency.
+- Tests: `crates/ui-egui/tests/it/main.rs` links the integrated UI tests; `apps/pdfcraft/tests/it/main.rs` links twelve winit source guards; `crates/ui-egui/src/control.rs` has the in-crate control/pointer probes; `crates/ui-egui/tests/perf.rs` is the existing timing harness.
+
+Targets to keep green:
+
+- `apps/pdfcraft` (native binary; wgpu plus glow fallback, accesskit, persistence, links, x11/wayland, native clipboard).
+- `apps/pdfcraft-web` (wasm32, eframe glow; no egui-winit clipboard feature is needed or available there).
+- `apps/pdfcraft-cli` (no egui dependency; unchanged).
+- `crates/ui-egui` (library, unit tests, `tests/it` integrated binary, `tests/perf.rs`, `examples/shot.rs`).
+- `xtask` gates (`fmt`, clippy, test, layers, wasm, assets, deny, parity).
+
+## 2. Actual lifecycle, features and compatibility surface
+
+### 2.1 App boundary
+
+`PdfCraftApp` is declared in `crates/ui-egui/src/lib.rs`; the eframe implementation is `impl eframe::App for PdfCraftApp`:
+
+- `raw_input_hook` applies line-scroll speed and injects the OS drag pointer position before egui reads the frame.
+- `save` repairs minimized-window storage through `window_state::WindowState::keep`.
+- `logic` owns host-side work: context capture, window repair, i18n selection, font installation, UI scale, drag/drop completion, inbox/open queues, OS events, control-channel requests, quit guard, autosave, file watching, update/print/export/OCR/optimize/action polls, deferred shortcuts, per-view input blocking, pending edits and picker completion.
+- `ui` owns per-pass layout: title command, full-screen or normal panels, tab strip, mode bar, right rail, docking or read-mode central panel, palette, dialogs, progress, toasts, then `finish_render_frame`.
+- `finish_render_frame` suspends hidden tabs' render pools and commits the visible/compare views' frame demand.
+
+`crates/ui-egui/src/canvas.rs` is a second lifecycle: `DocView::begin_render_frame` resets demand and the frame queue; `DocView::finish_render_frame` builds the render queue, feeds the pool and calls `DocView::receive` for a bounded upload batch.
+
+### 2.2 Lifecycle truth: `logic` is not a frame clock
+
+At the pinned 0.37 source, both native eframe (`crates/eframe/src/native/epi_integration.rs::update`) and web (`crates/eframe/src/web/app_runner.rs::logic`) call `app.logic` and then `app.ui` inside the `Context::run_ui` closure. A discarded layout reruns both. Hidden or occluded windows can call `App::logic` through `Context::run_logic`, which updates only raw viewport/window-focus information; events, input time, layout and normal pass state remain from the previous UI pass. Input therefore belongs only in a known UI phase (`App::ui` or an explicit method it calls), never in background work that reads `ctx.input` under the assumption that the window is hidden.
+
+Two corrections are binding:
+
+- `ViewportInfo::visible()` describes minimized/occluded state; it does not prove that the current callback is logic-only. A hidden UI paint can be requested for screenshots or injected input.
+- After a normally completed `run_ui`, `current_pass_index()` is zero even after multiple passes: `ContextImpl::end_pass` takes the viewport output with `mem::take`, and `run_dyn` restores the count only immediately before the next UI pass. A first-pass guard does not by itself skip ordinary hidden `run_logic` calls. It is still not a frame clock and cannot supply fresh input.
+
+No `run_ui_with_logic`/E22 scheduler API is adopted. There is no stable one-frame boundary inside `run_ui`, and both hosts already run logic per pass. Queues keyed by consumed identity, command/generation identity and monotonic deadlines provide the required behavior.
+
+### 2.3 Hidden work and current input
+
+- `App::logic` may run repeatedly in one visible frame and may run alone while hidden. Autosave, recovery, playback/audio, open completion, file watching, polls and undo application stay there, but use monotonic elapsed time (`std::time::Instant`, `web_time::Instant` on wasm), not `ctx.input(|i| i.time)`.
+- Fresh wheel, pointer, keyboard and IME input is handled in `App::ui` before panels. `Motion::begin_pass` moves from `logic` into `ui` (before any widget reads wheel input) or is guarded by a fresh-UI-pass token; it must never consume the same `ctx.input` event twice.
+- The grid-drop deadline and control-adjacent timers use monotonic deadlines too.
+- UI-produced commands may commit promptly from the UI. The requirement is exactly-once consumption, not "never commit on a discarded pass": egui cannot know at commit time whether a later widget will request a discard. Screenshot completion and render queues may be cancelled without side effects; an edit/undo transaction may not be duplicated when the pass is replayed.
+
+### 2.4 Feature and cfg inventory
+
+| cfg / feature | Where it matters |
+|---|---|
+| `target_arch = "wasm32"` | `apps/pdfcraft-web`; `ui-egui` disables `file_watch`, `pickers`, `system_fonts`; `fill_sign` image inbox and host bridge; no native window and no egui-winit clipboard |
+| `windows` | hidden-maximized restore, DPI change, DWM frame, IME cursor, auto language, measurement units, DX12 presentation (`apps/pdfcraft/src/main.rs`, `motion.rs`, `single_instance.rs`, winit patches W1/W3/W4/W18/W19) |
+| `target_os = "macos"` | Apple events, traffic lights/full-size content view, ⌘Q menu (`craft-quit`), title-bar drag, IME commit/discard/emoji/Korean (W6–W10, W12, W22–W24, W26) |
+| `target_os = "linux"` | GNOME/Wayland frame decision, compositor GPU selection, Wayland regular clipboard and W15P PRIMARY (W15/W15P/E4), X11 DPI/IME (W5/W11/W20/W21), Wayland scroll phases (W13) |
+| `unix, not macos` | single-instance Unix socket, Wayland/X11 detection, fontconfig directory parsing |
+| `not unix` / other | Windows and wasm branches above; no silent fallback to a native-only API |
+| Native eframe features | `default_fonts`, `wgpu`, `glow`, `accesskit`, `persistence`, `links`, `wayland`, `x11`, **`clipboard`** |
+| `ui-egui` eframe features | `default_fonts`, `wgpu`, `accesskit`, `persistence`, `links`, **`clipboard`** for native consumer/test parity |
+| Web eframe features | `default_fonts`, `glow`, `persistence`, `accesskit`; no winit clipboard path |
+| egui features | `bytemuck` in `ui-egui`; `default_fonts` explicit; **`monochrome_emoji_fonts`** in every egui-consuming target that draws PdfCraft UI text |
+| eframe `system_fonts` | stays off; `NativeOptions::system_font_fallback = false` |
+
+`cargo xtask wasm` checks crates below L8; `cargo check -p pdfcraft-web --target wasm32-unknown-unknown` remains required for the actual web shell. A CI feature-identity assertion must show `egui-winit/clipboard` enabled for native roots after the migration, and `cargo deny`/`cargo metadata` must show exactly the approved fork sources.
+
+### 2.5 Control channel and screenshots
+
+`crates/ui-egui/src/control.rs` is the user-observable automation surface. Today it installs `ControlPlugin`, stores the AccessKit tree and injects queued input in hooks, handles requests in `Control::tick`, receives screenshots as `egui::Event::Screenshot`, sends `ViewportCommand::Screenshot(UserData::new(tag))`, crops and PNG-encodes in `screenshot_png`, and times out after 5 seconds. Its tests live both in `src/control.rs` cfg-test modules and `crates/ui-egui/tests/it/control.rs` (65 tests, linked by `tests/it/main.rs`), including discard handling and `screenshots_of_window_and_region`. PR 1 updates both sets.
+
+egui 0.37 removes `Event::Screenshot` and changes `ViewportCommand::Screenshot` to a one-shot `ScreenshotCallback`. A pending screenshot command itself asks the integration to paint a hidden window; `RequestPaintWhileHidden` is additionally required when injected input must be applied without a screenshot.
+
+`Shared::passes` is a pass counter, not a frame counter. The migration renames the unit to accepted frames and increments it in `output_hook` only when `output.platform_output.request_discard_reasons.is_empty()`; an intermediate discarded pass does not count. A request made before a forced discard is not answered before the intended number of accepted frames.
+
+### 2.6 Panels, docking and window chrome (planning baseline)
+
+PdfCraft uses the 0.37 `Panel` API already in its 0.36 form:
+
+- `chrome::tab_strip`: `Panel::top("tab_strip")`;
+- `chrome::mode_bar`: `Panel::top("mode_bar")`;
+- `chrome::right_rail`: `Panel::right("rail")` and `Panel::bottom("rail-nav")`;
+- read-mode inspector: `Panel::right("read_right_panel")`;
+- central panel in `lib.rs`.
+
+0.36 stores `PanelState` under the panel `Id` passed to the constructor. 0.37 derives it as `parent_ui.scope_id().with_salt(IdSalt::new(id_salt))`; the panel child `Ui` is also salted with the new panel ID. Every named panel key therefore changes, and in-panel widget/focus/scroll state may reset. This is not left to implementation: §6.2 migrates the persisted keys in the first compatibility PR and tests the upgrade from a 0.36 fixture.
+
+Docking is `crates/ui-egui/src/docking.rs`; `DockArea::new(egui::Id::unique("pdfcraft-docking"))` wraps `craft_ui::docking`. Persistence is PdfCraft's own `Workspace` JSON, not egui panel memory. `DockArea::direction` is a new opt-in stock-compatible API planned in craft-libs CL-3; the explicit RTL adoption in PR 4 waits for that reviewed revision. Its visual policy preserves saved physical splits, rectangles and logical tab order.
+
+### 2.7 Window frame, decorations and restoration
+
+`apps/pdfcraft/src/main.rs` owns native options, app creation and GPU setup. `apps/pdfcraft/src/decorations.rs` decides whether GNOME Wayland leaves the frame to the app. `crates/ui-egui/src/window_controls.rs` draws the app frame and resize edges, and `window_state.rs` repairs a 64×64 restored window.
+
+`craft-window` owns `Frame`, `Layout` and `Button`; `window_controls.rs` currently has distinct duplicate types and its own GNOME `button-layout` parser. The migration makes `window_controls` re-export `craft_window::{Button, Layout}` and removes the duplicate parser. `decorations::app_drawn` uses `craft_window::Choice::probe(Prefix::new("PDFCRAFT"))`; `PDFCRAFT_TITLEBAR` accepts `app`, `system` and `desktop` (the last two force the desktop frame), matching craft-window. PdfCraft still applies `with_decorations(false)` only when it will draw its own header bar, and the runtime “Use system title bar” preference still toggles `ViewportCommand::Decorations`; craft-window decides the startup frame, not the runtime preference. The probe is called once at startup and never from `App::ui`.
+
+### 2.8 Fonts and language
+
+`theme::install_fonts_for` calls `ctx.set_fonts(installed_font_definitions(cjk))`; `installed_font_definitions` appends one installed face plus optional script fallbacks. `theme::on_interface_baseline` computes `FontTweak::y_offset_factor` from primary and fallback metrics. `system_fonts::fallback` is the single-face, last-resort policy; `PDFCRAFT_SYSTEM_FONTS=0` disables it.
+
+At the planning baseline, the i18n layer preordered right-to-left translations at catalog load (`i18n::LangInfo.rtl`, `catalog.map_translations(display_rtl)`), and `bidi::display_rtl`, `bidi::visual`, `bidi::wrap` and `bidi::visual_auto` preordered runs because egui 0.36 does not. The current migration removed catalog preordering; `display_rtl` and the other preordering helpers remain test-only. The fork's E5/E12/E13/E15/E16/E17/E20 own reordering now. Keeping `display_rtl` in production alongside E5 would double-reorder text.
+
+### 2.9 Clipboard, IME and input
+
+Text copy/paste goes through egui events; images and file paste use `arboard` directly. Native eframe 0.37 no longer enables `egui-winit/clipboard` implicitly when `default-features = false`; without the explicit feature, text cut/copy/paste loses OS integration and the Wayland clipboard/PRIMARY path is compiled out. `arboard` image/file code can mask that loss in a superficial check.
+
+PdfCraft uses ordinary `egui::TextEdit` for its dialogs, forms, comments composer and text editor; it has no custom IME editor producer requiring an app-side surrounding-text adapter. The pinned egui `6d518fc` contains the TextEdit producer/`IMEOutput` surrounding-text path, and egui-winit calls `set_ime_surrounding_text`; native platform execution and outgoing-text tests remain unqualified.
+
+## 3. Dependency, lockfile and vendor audit
+
+### 3.1 Manifests
+
+| Manifest | egui/eframe facts and required change |
+|---|---|
+| `Cargo.toml` workspace | egui/eframe/egui_extras/egui_kittest 0.36; `[patch.crates-io]` contains `winit = vendor/winit` and `egui-wgpu = vendor/egui-wgpu`. Replace window-stack path patches with approved immutable fork revisions; retain PDF vendors |
+| `crates/ui-egui/Cargo.toml` | eframe features `default_fonts`, `wgpu`, `accesskit`, `persistence`, `links`; add `clipboard`; egui features gain `monochrome_emoji_fonts`; egui_kittest dev-dep `eframe`, `wgpu` |
+| `apps/pdfcraft/Cargo.toml` | eframe features `default_fonts`, `wgpu`, `glow`, `accesskit`, `wayland`, `x11`, `persistence`, `links`; add `clipboard`; Linux dev-dep winit 0.30 for the scroll-policy test |
+| `apps/pdfcraft-web/Cargo.toml` | eframe features `default_fonts`, `glow`, `persistence`, `accesskit`; no clipboard feature or egui-winit dependency |
+| `apps/pdfcraft-cli/Cargo.toml` | no egui/eframe; unaffected |
+
+egui 0.37 no longer enables `default_fonts` by default. PdfCraft explicitly enables it in its own features. `monochrome_emoji_fonts` is chosen (not replacing `✔`/`▲`/`▼` with new SVG glyphs): the fonts are already OFL/MIT, attributed, and preserve existing text symbols deterministically with `PDFCRAFT_SYSTEM_FONTS=0`. The painted submenu arrow is not a font glyph after 0.37 and needs no emoji font.
+
+### 3.2 Lockfile duplicates and family resolution
+
+At planning time the lockfile contained one egui family at 0.36.2; the current qualification lockfile resolves the family at 0.37.0 (see `Current qualification state — 2026-10-25`). Several `vello_common`/`vello_cpu` minors still come through the PDF renderer and epaint. The target state must prove one egui family, one epaint family and one winit:
+
+- `egui`, `epaint`, `emath`, `ecolor`, `eframe`, `egui-winit`, `egui-wgpu`, `egui_extras`, `egui_kittest` all at 0.37.0 from one source.
+- `winit` at 0.30.13 with the craft language patches, from one source.
+- `wgpu` remains 30.x; `egui-wgpu` matches the resolved wgpu.
+- `accesskit` moves 0.24.x → 0.25.x; `accesskit_winit` 0.32.x → 0.34.x; epaint moves to `vello_cpu` 0.2.0 while hayro remains on 0.0.8. E11 is not required for PdfCraft because these versions cannot unify (verify with `cargo tree -e features -i vello_cpu`).
+- Verify `cargo metadata` package versions and sources, not tag names.
+
+### 3.3 Vendored winit provenance and compatibility
+
+`vendor/winit` is 0.30.13 (`vendor/winit/.cargo_vcs_info.json` = `e9809ef5…`) and carries **W1–W13**, not W1–W15. It has no language APIs. The planning-era candidate winit fork `8b35388b` carried W1–W15 plus W17–W27 but not W15P; W16 is not in this cut. W14 (`c488d2e9`, macOS cancelable termination plus `dpi` from crates.io) and W15 (`cf73a29c`, `b05ce129`, per-seat Wayland data device and regular clipboard) are in the fork, not the current vendor.
+
+W14 remains opt-in in the shared winit revision and is **not enabled** by PdfCraft; its existing termination path stays `craft-quit`. Validate that `dpi` resolves once with the git source. W15 regular clipboard is required by E4. In the planning-era candidate `8b35388b`, the **W15P** PRIMARY implementation was a prerequisite added by the shared winit work, using SCTK 0.19.2's `PrimarySelectionManagerState`/device/source/offer on the existing connection and event queue, and had to land before egui P2b. The current pin `a517b384` contains W15P (`PATCHES.md` W15P row; `src/platform_impl/linux/wayland/clipboard.rs`) and W27; native evidence remains open. No second regular `wl_data_device` is acceptable.
+
+The egui fork requires companion winit APIs on their target platforms. Integrate and review the series in the approved public storytold fork, compare every current PdfCraft vendor delta, transfer behavioral tests, then replace the path patch with the final immutable git revision. Record provenance and old/new source hashes in migration evidence. Keep the original vendor until equivalence is established; do not publish an interim personal-fork branch dependency.
+
+### 3.4 Source-guard migration and exact inventory
+
+`apps/pdfcraft/tests/it/main.rs` links twelve winit guard modules. All twelve must be transferred to the winit fork (or replaced by equivalent fork-owned immutable tests), and only behavioral/ABI tests remain in PdfCraft:
+
+`winit_macos_emoji_picker`, `winit_macos_ime_commit`, `winit_macos_ime_discard`, `winit_macos_korean_first_key`, `winit_macos_korean_space`, `winit_macos_title_bar_drag` (W12), `winit_wayland_scroll` (W13), `winit_wayland_text_input` (W2), `winit_windows_hidden_maximized` (W4), `winit_windows_ime_cursor` (W3), `winit_x11_dpi` (W11), `winit_x11_ime_focus` (W5).
+
+PdfCraft keeps the retained `vendor/winit` and `vendor/egui-wgpu` copies as provenance and may read them only for provenance assertions (W1 patch text, base hashes, the W1–W13/E2+E3 rows), never as proof of the code the app runs. The resolved graph is checked from `Cargo.lock`: `vendor_graph.rs` requires the exact canonical storytold git URL, 40-character revision and fragment for the two crates it inspects, `winit` and `egui-wgpu`, and rejects path sources. W17 covers W2, W3, W5–W10, W12 and W13; add W1, W4, W11 and the egui-wgpu behavioral coverage to the same central evidence map. The W15/W15P guard belongs on the winit fork or a behavior test, never on `vendor/winit`.
+
+### 3.5 Vendored egui-wgpu provenance
+
+`vendor/egui-wgpu` is 0.36.2 (`49682f8b…`) with E2+E3. The target is 0.37.0 plus the same two patches. The reviewed fork's E2+E3 commit is `9dd799ab` and adds a `surface_fit` unit test; PdfCraft also has stronger guards:
+
+- `apps/pdfcraft/src/main.rs::a_window_larger_than_the_gpu_limit_gets_a_surface_within_it`
+- `apps/pdfcraft/src/main.rs::surface_fit_never_empties_or_overflows_a_surface`
+- `apps/pdfcraft/src/main.rs::vendor_provenance_egui_wgpu_surface_fit_identity`
+- `apps/pdfcraft/src/main.rs::a_gpu_error_while_a_window_is_set_up_is_returned_not_a_panic`
+- `apps/pdfcraft/src/main.rs::vendor_provenance_egui_wgpu_catch_errors_identity`
+- `apps/pdfcraft/src/main.rs::pipeline_creation_error_is_returned_and_device_remains_usable`
+
+Integrate E2+E3 and the behavioral regressions into the central 0.37 fork, then consume the approved revision. Replace the source-path/source-absence assertions with immutable package identity checks. `surface_texture_limits` and `configure_gpu` remain: the first raises the enabled 2D limit, the second preserves adapter selection, DX12 presentation and indirect-validation behavior.
+
+### 3.6 craft-libs: port only, and account for craft-print/GDI/rgb drift
+
+PR 199's egui port changes `craft-ui` roles, `Id::unique`/`Ui::scope_id`, `egui_extras`/`egui_kittest` 0.37, and the docking fixture's `⋮` → `…`. Reuse those API hunks on current main; do not import the stale tree. PdfCraft needs `craft-ui` for docking/icons/tabs/layout, `craft-window` for the frame decision, and no wholesale move of its PDF-specific print UI into `craft_ui::printing`.
+
+Bumping all four craft-libs crates from their four current pins listed in section 1 to a revision based on `3832c47` carries more than a new field:
+
+- `craft-print` adds the unconditional `craft-winprint-gdi` dependency (`storytold/winprint.rs`, revision `417ac3c4…`), a public `rgb` re-export of the GDI transport, `lpstat -l` description parsing and `Printer.description`.
+- Audit `craft-winprint-gdi` licensing/target cfg/`cargo deny`/Windows build, and the non-Windows `rgb::PrintError::Unsupported` behavior.
+- `Printer` now has `description`; update every literal in the repository. At baseline there are 19 `Printer { … }` literals across `crates/print` and UI tests, not 13. This is a mechanical compile fix, with the craft-print tests and Windows native checks re-run.
+- Keep PdfCraft's own `print_ui.rs` sheet preview and options. `description` is not automatically displayed; a product change to show it is separate.
+- The current main already includes intervening security bounds, settings merge, docking permissions and linear printer-name collision checks; preserve them. The shared-library plan's CL-1 diff gate remains mandatory.
+
+### 3.7 Publication and duplicate-resolution rules
+
+- Pin immutable revisions. A branch name is not a pin.
+- `[patch.crates-io]` in the egui or winit repository does not propagate into PdfCraft. PdfCraft's root must patch every resolved egui-workspace package, including `egui_glow` for GL, `epaint_default_fonts`, the used core/render/test crates, and winit.
+- Use approved public immutable storytold fork revisions after vendor equivalence review. Never add a machine-local absolute path patch or publish another vendor fork to bypass dependency publication.
+- Add a CI assertion that `cargo metadata` resolves exactly one package ID for each family crate and one winit, and that no `path` dependency points outside the repository.
+
+### 3.8 Vendors outside the UI port
+
+`vendor/hayro*`, `vendor/lopdf` and `vendor/vello_common` are renderer/text-engine vendors. Keep their revisions, patches and tests. Inspect vello package identities and feature unification; incompatible versions may legitimately coexist. Do not force unrelated major versions to unify or edit PDF renderer vendors merely to make `cargo tree -d` empty.
+
+## 4. egui 0.37 breaking changes that touch PdfCraft
+
+| Change | PdfCraft use | Required action |
+|---|---|---|
+| `default_fonts` no longer a default feature | explicit in ui-egui, pdfcraft, web, craft-ui dev-dep | keep explicit |
+| `monochrome_emoji_fonts` gates emoji faces | `✔`, `▲`, `▼` and previously `⏵` text | enable the feature; add `egui-icons.ttf` attribution; keep painted submenu arrows out of font coverage |
+| eframe `clipboard` becomes explicit | native eframe with `default-features = false` | enable in native app and native UI tests; web needs none; add feature-identity check |
+| `WidgetType` deprecated alias for `Role` | 52 references, 56 `widget_info` closures | map roles explicitly |
+| `Id::new` deprecated → `Id::unique` | 74 references | semantic rename |
+| `Ui::id()` deprecated → `Ui::scope_id()` | 20 references | mechanical rename; `scope_id()` is the value `id()` returned, not a new inherited ID |
+| `UiBuilder::id` deprecated → `scope_id` | `canvas.rs:2607`; not `chrome.rs:697` | rename only the UiBuilder call |
+| `Panel` constructors take `AsIdSalt`; panel keys derive from parent scope | 5 panels | migrate 0.36 `PanelState` keys in PR 1 and test the upgrade |
+| `Ui::shrink_clip_rect` for panels | all panel content | test clip intersection and overlays |
+| `ViewportCommand::Screenshot` callback; `Event::Screenshot` removed | `control.rs` | bounded weak-slot callback; screenshot command itself paints a hidden window |
+| `Event::MouseWheel` gains `source: MouseWheelSource` | 41 references | add source; use `Unknown`/`Wheel`/`Trackpad`/`Momentum` only |
+| `ScrollStyle.kinetic` / rubber-banding | `fling.rs`, `wheel_pager.rs`, `canvas.rs` | keep PdfCraft fling as document owner; leave egui kinetic for ordinary ScrollAreas; prove one curve |
+| `NativeOptions.system_font_fallback` and `system_fonts` feature | not enabled today | set false and guard |
+| kittest panics on missing glyphs and unnamed inputs | 204 harness constructions in `tests/it` | fix names/glyphs in PR 1; no global disabling |
+| `Event::PasteImage`, `MiddleClickPaste`, PRIMARY | image paste via arboard | adopt the W15P PRIMARY contract; no app-level filtering of the event |
+| `Response::accessible_name`, `Ui::label_inputs_by`, `Ui::name_inputs` | custom widgets and text fields | use for accessible names |
+| Submenu arrow is a painted `arrow_atom` | test labels `"File ⏵"`, `"View ⏵"`, etc. | update labels/accessible names and keep an arrow-painted assertion |
+
+## 5. Fork patch audit: E1–E21 and E21b (planning-era baseline)
+
+Base: `0.37.0` = `841a328b`. The E1–E21 audit below was made against the planning-era fork head `a4f9a17f`; the current qualification pin is `6d518fc` (see `Current qualification state — 2026-10-25`), and the E21b row records the later pin. The patch table in the fork's `PATCHES.md` is provenance; each row was re-audited against the source at `a4f9a17f` and PdfCraft's needs, so rows naming `a4f9a17f` are planning-era history.
+
+| # | Fork commits | Crate | Upstream status at 0.37.0 | PdfCraft need | PdfCraft tests / removal condition |
+|---|---|---|---|---|---|
+| E1 | `8f3abf06` | eframe | not upstream; `ViewportHooks` absent | none today: PdfCraft opens one root viewport; `--new-window` is a separate process | compile only; keep for craft-tablet. Remove when upstream adds per-viewport hooks or craft-tablet no longer needs it |
+| E2+E3 | `9dd799ab` | egui-wgpu | not upstream; #8361 open | required: `Surface::configure` panic and start-up errors | six `apps/pdfcraft/src/main.rs` surface/GPU guards plus fork-owned behavioral tests; remove when upstream fixes #8361 and the start-up error path |
+| E4 | `66bacf23` | egui-winit | upstream #8657 draft; 0.37 still uses smithay | required on Hyprland and every Wayland compositor serving one data device | W15 regular clipboard plus W15P PRIMARY; native Wayland single-data-device test; remove when upstream has the behavior |

+
+### 5.1 Audit notes and traps
+
+- **E2+E3 are not one patch.** The surface fit and the error scopes protect different failures.
+- **E4 + W15P.** Regular clipboard uses the winit data device (W15). PRIMARY is a distinct protocol object on the same connection/event queue and per-seat lifecycle (W15P), using SCTK's PRIMARY objects. It must not bind a second regular `wl_data_device`. Preserve password exclusion and no unchanged-selection reclaim. No “filter `MiddleClickPaste`” substitute is acceptable.
+- **E21b is present in the pinned tree.** The planning-era candidate lacked the producer; pinned egui `6d518fc` contains the TextEdit producer/`IMEOutput` path and egui-winit calls `set_ime_surrounding_text`. PdfCraft uses ordinary TextEdit, so it needs no custom model adapter; native platform execution and outgoing-text tests remain open.
+- **E5/E12/E13/E16 are a dependency chain.** Do not cherry-pick E12 without E5 or E13/E16 without E5.
+- **E14 supersedes PdfCraft's baseline hack but not its Windows hinting.** Keep JetBrains Mono `HintingTarget::Smooth`.
+- **E15/E20 change line breaking.** Native wrapping must be the only wrapper once active.
+- **E17/E20 do not automatically force base direction.** PdfCraft sets `TextDirection::RightToLeft` where the UI locale requires it.
+- **E19 is useless without W23/W25; E21 is useless without W26/W27.**
+- **E11 is not required by PdfCraft.**
+
+### 5.2 winit patch provenance and compatibility
+
+Base: `v0.30.13` = `e9809ef54b18499bb4f2cac945719ecc2a61061b`.
+
+The retained vendor carries W1–W13. The planning-era reviewed language branch `8b35388b` carried W1–W15 plus W17–W27 but not W15P. W16 is not in this cut. The current pin `a517b384` contains W15P PRIMARY and W27 (`PATCHES.md`); native evidence remains open.
+
+| Group | Patches | Purpose | Upstream / removal |
+|---|---|---|---|
+| Windows DPI/frame/IME | W1 `b357a332`, W3 `fd104a4c`, W4 `3fffb7ce`, W18 `894bf2d7`, W19 `fa2e1b3d` | mixed-DPI suggested rect, Korean IME cursor, hidden maximized restore, hidden system caret, IME-consumed key presses | W1 merged on master; W3/W4 open; W18/W19 to be proposed |

+| X11 | W5 `283370ce`, W11 `4df8554b`, W20 `019c95f1`, W21 `23bb19a7` | focused replacement IME context, server DPI fallback, one input context per window, quiet IME spot | W5 open; W11/W20/W21 to be proposed; W20 supersedes W5 |
+| macOS | W6 `a82b90fb`, W7 `9b90d5bd`, W8 `6a87addd`, W9 `9500f25d`, W10 `4a7dd791`, W12 `7facf001`, W14 `c488d2e9`, W22 `0816871e`, W23 `c8cd8aa1`, W24 `4b5bc5a0`, W26 `2b9cd1cf` | NSTextInputClient commit flow, discard marked text, emoji picker, Korean space/first key, title-bar drag, cancelable termination, IME ranges, ⌘-layout names, reset, byte-count delete | W14 is opt-in and not enabled by PdfCraft; others open/to be proposed |
+| Language/tests | W17 `2be27382`, W25 `eb4007da` | regression source guards; `platform::latin_layout::KeyEventExtLatinLayout` | tests go with their patches; W25 required by E19 |
+
+Compatibility rules:
+
+- The egui fork's `egui-winit` calls `winit::platform::latin_layout::KeyEventExtLatinLayout`, `KeyEventExtMacOS::key_with_command`, `WindowExtMacOS::take_ime_delete_surrounding` and `WindowExtWayland::take_ime_delete_surrounding`; E21b also calls `WindowExtWayland::set_ime_surrounding_text`.
+- W14 remains compiled in the shared fork but not opted into by PdfCraft; `craft-quit` remains its terminate path.
+- Re-run winit policy/unit tests in the selected fork and app-facing regressions. Native IME/compositor acceptance still requires actual workflows.
+
+## 6. Migration design
+
+### 6.1 Frame boundary and exactly-once side effects
+
+Keep the existing `eframe::App` hooks. Adding a private phase type is allowed only if implementation proves it simplifies real state ownership; do not add a scheduler API or rerun the whole app through a blanket `Context` bridge.
+
+1. `logic` remains the owner of queues, autosave, recovery, file watching, open completion, background polls, control request admission, undo application and other host state. Replayed passes must not re-enqueue an action, duplicate a command or add a second undo step.
+2. UI-produced editing commands may apply in the UI, as they do today (`chrome.rs`, `canvas.rs`, `dialogs.rs` call `execute`/`apply_edit`). Preserve promptness. The rule is exactly-once by command/response ID or document generation, not “zero commits on discard”. A discarded pass may repeat layout; it must not repeat the edit.
+3. Inventory every UI-side `execute`/`apply_edit`/undo path and add a forced-late-discard test using a real toolbar action. A per-pass pending-command queue keyed by `Response::id`/command identity is preferred over moving all UI side effects into logic.
+4. `DocView::begin_render_frame` may collect per-pass demand. Render/upload commits use document/render generation, not `!ctx.will_discard()` as the correctness boundary. A late discard may discard demand work but must not lose an already-produced first-pass texture.
+5. `Control::tick` remains in `logic` for queue servicing. It sends `ViewportCommand::RequestPaintWhileHidden` while a screenshot or injected input waits. Injected input is consumed once; a replay does not replay the click.
+6. Autosave, recovery, grid-drop timeouts and playback use monotonic time. `Motion::begin_pass` is called from `ui` before panels; no logic-only call consumes `ctx.input` or smooth-scroll state.
+7. `Frame::set_ui_language` runs after language resolution, once per pass only when the resolved language changes; it does not read stale input from `logic`.
+8. Never infer a logic-only phase from `visible() == Some(false)`; hidden UI paint is a known UI phase and must handle current input.
+
+### 6.2 Panels, docking and persistence
+
+Current integration note: the shared side panes and rail described at the top supersede the former docking and panel layout below. Retain historical requirements as context, not as claims of implemented capabilities.
+
+
+The first compatibility PR implements an actual one-time panel-key migration. For each of `"tab_strip"`, `"mode_bar"`, `"rail"`, `"rail-nav"` and `"read_right_panel"`:
+
+- old key (0.36): `Id::new(salt)`;
+- new key (0.37 root panel): `ctx.viewport_id().root_ui_id().with_salt(IdSalt::new(salt))` (equivalently `parent_ui.scope_id().with_salt(IdSalt::new(salt))` for the root).
+- Before the first 0.37 UI pass, if the new key has no persisted `PanelState` and the old key does, read the public `PanelState` and insert it under the new key. Keep the old key untouched for rollback. Do not reset a width that can be migrated.
+
+Test with a synthetic 0.36 memory fixture: write the old key with a known outer width, run the 0.37 app, and assert the panel width survives within 1 point. Dump the old/new IDs for one panel and one child widget. A one-time reset of transient in-panel focus/scroll state is explicitly accepted only if the upgrade test demonstrates it; persisted widths are not reset. PdfCraft's own `docking::Workspace` layout is not touched.
+
+Further tests:
+
+- Panel order: tab strip → mode bar → right rail → central panel. Read-mode inspector must not reorder the rail or duplicate a panel ID.
+- A panel's content clip is a subset of the panel rect and parent clip; popups/comment overlays use `Area`/`Window` layers.
+- Floating docking, tab detach, group move and split resize survive restart from `Workspace` JSON, not egui memory.
+- `DockArea::new(Id::unique("pdfcraft-docking"))`; keep the same salt for craft-ui state. If RTL is selected, pass the explicit direction; persisted split/rectangles/logical tab order stay unchanged.
+
+### 6.3 Viewports
+
+PdfCraft has no deferred or immediate child viewports. Keep `ViewportId::ROOT` as the only production viewport. `window_state` and tests already use it. E1 `ViewportHooks` remains a suite feature, not a PdfCraft requirement. Do not add popout document windows in this port.
+
+### 6.4 Screenshot callback correlation
+
+Replace `ViewportCommand::Screenshot(UserData)` plus `Event::Screenshot` with a bounded, cancelable request record:
+
+- one completion slot per admitted request, owned by that request; the callback holds only a weak reference to the slot;
+- callback stores at most one `Arc<ColorImage>` and wakes the owning root viewport after releasing the slot lock; it never encodes PNG, writes a file, runs commands, or strongly captures `Context` in a cycle;
+- `Context::request_screenshot` or `ViewportCommand::Screenshot` with the one-shot callback; `finish_pending` takes each completed slot exactly once and replies on the app thread;
+- cancellation, timeout and viewport close drop/cancel the slot so a late callback cannot produce a file or second reply;
+- admission defaults are 4 requests, 128 MiB/image and 256 MiB aggregate reserved
+  in-flight/completed image bytes. These cap pending requests and aggregate image bytes. Reserve checked bytes before issuing a capture, using the allowed surface dimensions; revalidate dimensions before issuance after resize/DPI changes. Release reservations on completion, cancellation, oversize/stale rejection and shutdown; tests assert retained bytes return to zero;
+- store issuance-time target-UI logical viewport rect, `pixels_per_point`, requested region
+  and geometry epoch in the slot. Reject/retry any resize/DPI/zoom/surface epoch change
+  before save, even a change back. Callback arguments contain pixels only. The callback image may be smaller because E2 surface fitting reduced it; derive x/y image scale from the returned dimensions and recorded logical bounds, verify aspect/rounding, and do not use `ctx.pixels_per_point()` at completion. A resize/DPI generation mismatch retries within the deadline or returns a defined error;
+- PR 1 waits for the approved craft-ui CL-2F completion-slot helper and adopts it directly; no temporary app-local implementation. Preserve PdfCraft request/path/region/reply policy in `control.rs`.
+
+Hidden-window tests are separate:
+
+- a hidden window with queued injected input needs `RequestPaintWhileHidden` to apply it; without the command the input times out;
+- a pending screenshot command itself requests a paint. A request still queued in app
+  logic, or awaiting settling before UI issuance, needs `RequestPaintWhileHidden` to reach
+  that point; test admission and already-issued capture separately;
+- keep late-callback, cancellation, two-region/out-of-order, close, admission overflow and DPI-change tests. Assert exact reply counts, dimensions/pixels, bounded memory and eventual queue drain.
+
+The dependency boundary also requires P2b's bounded asynchronous W15/W15P transfer API
+(total deadline, cumulative byte cap, bounded workers/queue, completion wake and cancellation),
+and P7's emitted-key identity paired by physical key for repeat/release. PdfCraft adds slow/trickle,
+oversized/canceled paste and event-loop responsiveness checks, plus ordinary held-key/Ctrl+Z
+layout-switch, release-modifier-first and focus-loss cases. Do not copy those internals locally;
+consume the reviewed revisions and assert app-visible behavior. Clipboard shortcut keydown may
+be intercepted before egui sees a Key event, so Ctrl+C/Cmd+V alone is not a stuck-key test.
+
+### 6.5 Fonts and glyph coverage
+
+Keep PdfCraft's single-face, last-resort system-font policy. Do not enable eframe's `system_fonts` provider silently. Set `NativeOptions.system_font_fallback = false` and keep a source/feature guard that `eframe/system_fonts` stays off.
+
+Glyph decision: enable `egui/monochrome_emoji_fonts` in `pdfcraft-ui-egui`, the native app and the web dependency graph. This keeps the existing `✔`, `▲` and `▼` text symbols and the OFL/MIT attributed Noto Emoji/emoji-icon fonts deterministic with `PDFCRAFT_SYSTEM_FONTS=0`; do not replace them with new SVG assets in this migration. The new painted submenu arrow is an atom, not text, and is removed from glyph expectations.
+
+Attribution and assets in the first green PR:
+
+- treat the 0.37 font change as a deliberate fixture change: `⋮` (U+22EE) was never covered by the bundled faces, and the craft-libs test fixture moves to `…`; do not restore a tofu-drawing fixture. Production `…`/`−` remain covered;
+- update all four `[[bundled]]` `epaint_default_fonts` entries from 0.36.2 to 0.37.0;
+- add `egui-icons.ttf`, SHA-256 `122806555c73df7cef55aa1d945289ae27fbc4dbbd31abbb4204ee0cda829cc8`, recorded as the MIT-licensed `emoji-icon-font` subset by John Slegers, with its exact usage;
+- run `cargo xtask assets --write` and then `cargo xtask assets`.
+
+Adopt E14 for fallbacks: set `FontTweak::fallback_align = FallbackAlign::Baseline` for script fallbacks; remove metric-derived `y_offset_factor`; keep Windows JetBrains Mono hinting. Add a glyph-coverage test for every UI literal and catalog translation with `MissingGlyphPolicy::Panic` (or `Fonts::has_glyphs`) for embedded-only, craft-fonts, each script fallback, and `PDFCRAFT_SYSTEM_FONTS=0/1`. A missing glyph is a failure, not a snapshot update.
+
+### 6.6 Language and RTL
+
+Current integration note: the shared side panes and rail described at the top supersede the former docking and panel layout below. Retain historical requirements as context, not as claims of implemented capabilities.
+
+
+End state:
+
+- `logic` resolves the language and calls `frame.set_ui_language(Some(code))` (E18), setting `Context::language` (E17).
+- Translated UI text stays logical in catalogs. Remove `catalog.map_translations(display_rtl)`, `bidi::display_rtl` and the matching label preordering. Rely on E5/E12.
+- Use explicit `TextDirection::RightToLeft` for `ar`/`ckb` labels whose first strong character may be Latin or a placeholder; use `LeftToRight` for file/path labels where the extension must stay at the end; use `Auto` for document-authored text. A small local direction helper is used only where multiple call sites need it; no new fork-only API.
+- Replace `bidi::wrap`/`widgets::wrapped_text` with native `Label`/`LayoutJob` wrapping once E15 is active. A remaining custom wrapper must measure with the same direction/language it paints.
+- Set `Style::right_to_left` for `ar`/`ckb` after auditing manual `Layout::right_to_left` call sites. E9 mirrors chrome, not every manually positioned control. Pass an explicit direction to `craft_ui::DockArea`; do not reverse saved workspace order.
+- Keep `bidi::visual` only for painter paths that cannot use a `LayoutJob`; never combine it with native bidi on the same text.
+- AccessKit labels and copied text stay logical; only painting is reordered.
+
+### 6.7 Input, IME and clipboard
+
+- Add `source` to every `Event::MouseWheel` constructor. The only variants are `Unknown`, `Wheel`, `Trackpad`, `Momentum`. On Wayland, Windows, X11 and web, winit reports `Unknown`; macOS reports `Wheel`, `Trackpad` or `Momentum`.
+- PdfCraft's `fling.rs` remains the document-motion owner. On non-macOS platforms it keeps the existing `MouseWheelUnit::Point` + `TouchPhase::End` heuristic, explicitly including `Unknown`; never use the invented `Finger` or `WheelTilt` egui variants. On macOS its custom fling stays off because the OS sends `Momentum`; test that egui kinetic does not add a second document glide. Ordinary widget `ScrollArea`s keep the egui kinetic default; wheel deltas do not create coast velocity, only pointer-drag velocity and momentum do.
+- E10/E19/W23/W25: verify shortcuts on non-Latin layouts through synthetic `RawInput` and native Windows/macOS/Linux tests.
+- E21/W26/W27: test incoming `DeleteSurroundingBytes` and outgoing E21b surrounding text after delete/commit, deletion-only batches, preedit exclusion, reversed selection, UTF-8 boundaries, long/over-limit selections, field/window switching, password clearing and late serials.
+- Text copy/paste stays on egui events; keep `arboard` for image/file clipboard. Enable eframe `clipboard` for native builds. PRIMARY uses W15P: keyboard-only focus, serial freshness, owner/seat changes, empty/absent offers, self-paste, canceled/slow transfers, password exclusion and no unchanged-selection reclaim. Native evidence on wlroots/KWin/Mutter. No second regular data device.
+
+### 6.8 Accessibility
+
+Current integration note: the shared side panes and rail described at the top supersede the former docking and panel layout below. Retain historical requirements as context, not as claims of implemented capabilities.
+
+
+- Map every `WidgetInfo` role explicitly (`Role::TextInput`, `Role::CheckBox`, etc.).
+- Add accessible names to every input widget. 0.37 kittest fails unnamed inputs; use `labelled_by`, `Ui::label_inputs_by`, `Ui::name_inputs` or `Response::accessible_name`.
+- Keep logical labels in AccessKit. Do not set preordered visual strings.
+- `ControlPlugin` copies the AccessKit tree; `ui.inspect` must keep stable widget IDs across panel migration. Test roles/labels for text field, slider, tab and custom button.
+- Panel resize handles expose `Role::Splitter`.
+
+### 6.9 Rendering and GPU
+
+- Keep `surface_texture_limits` and `configure_gpu`. E2+E3 remain required.
+- Do **not** skip `DocView::receive` uploads on `will_discard`. A first-pass texture is carried into the final merged `TexturesDelta`; skipping it can lose a page. Use generation identity to avoid re-scheduling renders and avoid duplicate whole-image deltas.
+- Assert the final merged `FullOutput.textures_delta.set` contains one whole delta per texture generation; a forced-late-discard test must show the page after the next accepted pass.
+- Keep `RESULTS_PER_FRAME`/`UPLOAD_BYTES_PER_FRAME`, hidden-tab suspension, `PDFCRAFT_RENDERER=wgpu|gl`, OpenGL retry and software-renderer notice.
+- Screenshot readback is callback-driven; never assume it is ready in the same input frame.
+
+### 6.10 Commands, undo and persistence
+
+No command ID, tool ID, `parity/` entry, undo transaction or saved-settings key changes in this port. Preserve `commands.rs` registry IDs, `Session` document generations and undo steps, `Workspace` JSON, `window_state` storage key `window`, and `persist()` keys `pdfcraft`/legacy `printcraft`. The only persistence migration is egui's panel `PanelState` keys in §6.2.
+
+## 7. PR stages and rollback
+
+All publication is gated by explicit human approval. No push or PR is authorized by this plan.
+
+### Stage 0 — harness and baseline (before production change)
+
+- Land only this document and a test-only measurement driver/harness; no production behavior changes.
+- The harness must run on the unmodified baseline `a2ec27b` and, where its adapter permits, stock 0.36.2, stock 0.37.0 and the fork.
+- Record baseline frame/idle/RSS samples, `Context::tessellate` with 120 ASCII labels (#8731), startup phase split (instance/adapter/device → pipeline creation → first frame; #8736), and font install/discovery with `PDFCRAFT_SYSTEM_FONTS=0/1` and provider on/off (#8512).
+- Record `cargo metadata`, lock hash, vendor hashes, hardware, renderer/driver, DPI, fixtures and actual commands. A baseline may not be measured after production changes.
+
+### Shared fork prerequisites (external to PdfCraft)
+
+The implementation is blocked until the shared plans publish approved immutable revisions containing:
+
+- the reviewed winit W1–W15, W17–W27 and **W15P** PRIMARY path (all present in the current pin `a517b384`);
+- the reviewed egui E1–E21 and **E21b/P7b** outgoing surrounding-text integration;
+- the craft-libs API-port hunks on current main, with `craft-window` and `craft-print` drift reviewed.
+
+PdfCraft does not vendor a private copy or bypass missing publication with a path patch.
+
+### PR 1 — atomic first-green compatibility change
+
+Depends on: Stage 0 and the complete approved egui/winit revisions (P2b bounded W15/W15P, P7 key release pairing, P7b IME lifecycle, P7c selection fix), plus craft-libs CL-1/CL-2F. PR 4 RTL docking additionally waits for CL-3.
+
+Scope (one reviewable change set; commits may split by file only if every commit is green):
+
+- Pin the egui 0.37 family and winit 0.30.13 fork revision; update `Cargo.lock`.
+- Enable native eframe `clipboard` in `apps/pdfcraft` and `crates/ui-egui`; add the feature-identity assertion. State that web has no egui-winit clipboard.
+- Enable `monochrome_emoji_fonts`; update `ATTRIBUTION.toml` bundled versions and add `egui-icons.ttf`; run assets write/check.
+- Add storytold egui/winit git URLs to `deny.toml` `allow-git`; keep `unknown-git = "deny"`.
+- Rename `WidgetType`/`Id::new`/`Ui::id`/`UiBuilder::id`; map roles; fix all kittest accessible-name and missing-glyph failures (204 harnesses).
+- Update painted submenu labels: `"File ⏵"` → `"File"`, etc.; update AccessKit/name expectations across `commands.rs`, `theme.rs`, `editing.rs`, `control.rs`, `text_select.rs`, `view.rs`; assert the arrow is painted.
+- Add `MouseWheel.source` with the real variants; migrate the screenshot path to the bounded callback; add panel-key migration.
+- Port from craft-libs current main using only the reviewed API hunks and `craft-window`; add `craft-window` type reuse and retain `PDFCRAFT_TITLEBAR`/runtime preference semantics. Add `Printer.description` to every literal (19 at baseline) and audit craft-print/GDI/rgb drift.
+- Transfer winit/egui-wgpu source guards centrally; replace PdfCraft source-path and `source =` assertions with immutable git graph checks.
+- Remove catalog preordering and `display_rtl` as the fork becomes the sole UI bidi owner;
+  include the focused logical-text/selection regression in this first fork pin.
+- Do not defer names, glyphs, attribution, required bidi adaptation or `deny` to PR 3.
+
+Tests: fmt, clippy `-D warnings`, `cargo test -p pdfcraft-ui-egui`, `cargo test -p pdfcraft`, wasm check, `cargo xtask layers/assets/deny/parity`, native feature/graph assertions, source-guard replacements. Snapshot changes must be reviewed, never auto-accepted.
+
+Rollback: revert PR 1; keep the 0.36 lock and vendor directories in history. Do not leave a 0.37 manifest with a 0.36 lock.
+
+### PR 2 — lifecycle, control and render commit
+
+Depends on: PR 1.
+
+Scope:
+
+- Replace `ctx.input` clocks in autosave/recovery/grid/control timers with monotonic deadlines.
+- Move `motion.begin_pass` into UI before panels; remove stale event reads from logic-only iterations.
+- Complete exactly-once command/edit/undo handling with a real forced-late-discard test; remove any “no commit on discard” assumption.
+- Finish screenshot slot stress: hidden injected input, screenshot command paint, cancel/late/out-of-order/DPI, aggregate reservations.
+- Rename `Pending::Frames`/`Shared::passes` to accepted completed frames; increment only when `request_discard_reasons` is empty; add a forced-discard timing test.
+- Add generation-safe texture tests; do not gate uploads on `will_discard`.
+
+Rollback: revert PR 2; PR 1 retains a complete 0.37 callback and basic regression coverage.
+
+### PR 3 — language, fonts, RTL and accessibility completion
+
+Depends on: PR 2.
+
+Scope:
+
+- `Frame::set_ui_language`; AccessKit language.
+- Expand native wrapping and explicit `TextDirection` tests; catalog preordering and
+  `display_rtl` removal already landed in PR 1 and must not be restored independently.
+- E14 fallback alignment; glyph coverage; `system_font_fallback = false`.
+- `Style::right_to_left` after manual-layout audit; craft-ui `DockArea::direction`.
+- Role/name tests already required by PR 1 are strengthened, not introduced here.
+
+Rollback: revert PR 3; PR 2 remains. If native bidi proves wrong, revert the whole 0.37 family to the 0.36 fork tag `767b1cad` with the old preordering.
+
+### PR 4 — platform window, packaging and documentation
+
+Depends on: PR 1 (can run in parallel with PR 2/3 after rebase).
+
+Scope:
+
+- The type re-export/parser replacement lands in PR 1; PR 4 completes extended native policy tests for `craft-window`: `window_controls` re-exports `craft_window::{Button, Layout}`; `decorations` uses `Choice::probe(Prefix::new("PDFCRAFT"))`; remove duplicate parser; keep runtime `Use system title bar` toggle.
+- Native Linux/Windows GUI checks, web build, packaging checks and clipboard/PRIMARY/IME workflows.
+- Update `vendor/README.md`/`SOURCE.json` only for retained vendors; document removed window-stack copies and exact replacement revisions.
+- Update `docs/development.md` and version statements.
+
+Rollback: revert PR 4; PR 1–3 remain.
+
+### PR 5 — performance evidence and final gates
+
+Depends on: all.
+
+Scope: run the Stage 0 harness on the candidate; add paired release results, stock-0.37 control, peak RSS, idle CPU/repaint, texture counters and startup/font/tessellation measurements; update `ROADMAP.md`/status docs. No behavior change.
+
+DAG:
+
+```
+Shared forks published -> Stage 0 -> PR1 -> PR2 -> PR3 -> PR5
+                                      \-> PR4 -> PR5
+```
+
+PR4 may be rebased alongside PR2/PR3, but do not land two PRs that both rewrite `lib.rs` without a rebase review.
+
+## 8. Test plan with user-observable assertions
+
+### 8.1 Existing suites to keep green
+
+- `crates/ui-egui/tests/it` (one binary): accessibility, actions, panels, controls, comments, content, editing, export, fonts, forms, links, pickers, print, recovery, signing, text selection, viewer, XFA.
+- `crates/ui-egui/tests/perf.rs`: collapsed comments, 500-page scrolling and panel budget tests.
+- `apps/pdfcraft/tests/it`: twelve winit guards (transferred/replaced), and the Wayland scroll-policy compile test.
+- `apps/pdfcraft/src/main.rs`: GPU/surface/adapter guards.
+- `examples/shot.rs`: headless screenshot of the real shell.
+- `crates/ui-egui/src/control.rs`: in-crate control, pointer and multi-pass probes.
+
+Include `crates/ui-egui/tests/it/control.rs`, its discarded-pass requests and `screenshots_of_window_and_region` in PR 1 migration and the existing-suite gate.
+
+### 8.2 New or strengthened assertions
+
+| Area | Test | Assertion |
+|---|---|---|
+| Lifecycle | `logic_runs_per_pass_but_one_action_commits_once` | Native/web-shaped driver runs logic + UI twice in one frame; one click yields one edit/undo step |
+| Hidden logic | `hidden_logic_advances_monotonic_deadlines` | Repeated `run_logic` with advancing wall clock and no new events autosaves once and changes no scroll/zoom |
+| Hidden input | `hidden_injected_input_needs_a_ui_pass` | Queued click times out without `RequestPaintWhileHidden`; applies exactly once with it |
+| E22 | `completed_multipass_resets_pass_index` | After completed `run_ui`, `current_pass_index()` is zero; a hidden call still runs; no first-pass guard is used as a scheduler |
+| Panels | `upgrade_from_036_panel_memory` | Old `Id::new(salt)` width migrates to root-scope key; width within 1 pt; ID dump recorded |
+| Panels | `panel_widget_id_stays_stable` | A widget in a panel keeps the same `scope_id`-derived interaction ID across consecutive 0.37 frames; `unique_id` is not substituted for state |
+| Panels | `panel_clip_is_intersected_with_parent` | Child clip no larger than panel/parent; overlay uses `Area` and remains visible |
+| Docking | `dock_float_detach_and_split_survive_restart` | Same `Workspace` JSON round-trips; panel bodies once; Canvas cannot float/share tabs |
+| Screenshots | `two_screenshot_requests_keep_their_slots` | Two regions complete out of order with own dimensions/colours; each reply once |
+| Screenshots | `hidden_screenshot_command_paints_itself` | A pending screenshot paints a hidden window; no false `RequestPaintWhileHidden` requirement |
+| Screenshots | `late_screenshot_is_dropped_after_cancel` | Timeout/close/cancel produces no second reply/file; reservations return to zero |
+| Screenshots | `dpi_change_uses_capture_geometry` | Request-time ppp/rect correlate the image; mismatch retries or errors, never crops with new scale |
+| Multi-pass | `discard_does_not_duplicate_edit_or_undo` | One toolbar action with `max_passes=2`: one edit, one undo step, one generation change |
+| Texture | `discard_keeps_first_pass_texture_and_deduplicates` | Final merged delta has one whole image per generation; page visible next accepted pass; no upload skip |
+| Control | `after_frames_counts_accepted_frames` | Forced discard does not answer early; answers after intended accepted frames |
+| Input | `unknown_wheel_source_keeps_wayland_fling` | `Unknown` + Point + End glides on Linux; `Trackpad`/`Momentum` policy covered; no `Finger`/`WheelTilt` |
+| Input | `one_finger_lift_glides_once` | Offset after 0.5 s follows `fling.rs`; egui kinetic adds no second document curve |
+| Fonts | `every_ui_string_has_all_glyphs` | All `tl!` literals and catalogs pass `MissingGlyphPolicy::Panic` for embedded + craft-fonts + system-font-off |
+| Fonts | `fallback_rows_share_the_baseline` | Fallback baseline equals primary; row grows; `y_offset_factor` not the mechanism |
+| Language | `arabic_ui_labels_use_an_explicit_paragraph_direction` | With an Arabic face, the label's paragraph direction is `RightToLeft` and its Latin run sits right of the Arabic; English stays `Auto` |
+| Language | `arabic_catalog_stays_logical` | Catalog and command lookups stay in logical order and placeholders keep their positions |
+| Language | `a_tab_with_an_arabic_file_name_keeps_its_logical_accessible_name` | AccessKit label is logical; paint is visual only |
+| Editing | `grapheme_caret_and_delete_are_cluster_safe` | Emoji ZWJ/combining accent move/delete as one cluster |
+| IME | `delete_surrounding_bytes_replaces_exactly` | Exact reported bytes deleted; one undo step |
+| IME | `outgoing_surrounding_text_is_fresh` | After delete+commit, preedit exclusion, cursor/selection changes, long/over-limit/password/focus cases; E21b payload present and bounded |
+| Accessibility | `all_input_widgets_have_names` | Every text input role has non-empty label; no global check disable |
+| Accessibility | `panel_tree_roles_and_order` | Tab strip, mode bar, rail and inspector once; expected roles/order |
+| Menu | `submenu_arrow_is_painted_not_named` | `"File"` etc. accessible labels; arrow atom visible; no `"File ⏵"` dependency |
+| Clipboard | `native_egui_winit_clipboard_is_enabled` | Native graph enables `egui-winit/clipboard`; web does not require it |
+| Clipboard | `wayland_text_clipboard_uses_one_data_device` | Regular clipboard works on Hyprland without a second regular device |
+| PRIMARY | `primary_selection_uses_w15p` | Password excluded, unchanged selection not reclaimed, serial/seat/offer/self-paste/cancel cases; single data device |
+| Selection | `textedit_selection_to_toolbar` | Select a subrange in the paragraph TextEdit, click Bold/colour/underline/spacing in Format and assert only that byte range receives `RangeStyle`, with one undo. Repeat via keyboard/focus surrender. `LineEditor.selection` is populated from cursor_range and used by `LineEditor::style` in `apply_line_format`; right-rail-before-central draw order may protect a path but is not proof. Final fork P7c owns #8763 fix (#8764 remains open/unmerged). #8748 is closed/unmerged and root-only PdfCraft has no child case |
+| Web | `web_named_keys_and_non_latin_shortcuts` | Named keys not typed as text; `Ctrl+S` works on Russian layout |
+| GPU | existing surface tests | 8600×3423 at 250% fitted to 8192; bad surface errors; pipeline error returns `CreateRenderer` |
+
+### 8.3 Deliberate broken-behavior probes
+
+Before accepting each test, temporarily revert the fix and confirm the named test fails:
+
+- remove `surface_fit` → surface-fit test fails;
+- remove `catch_errors` → GPU setup error test fails/panics;
+- re-add `display_rtl` to catalog lookups → `i18n::tests::arabic_catalog_stays_logical` fails;
+- switch E21 back to character counts or remove E21b payload → IME tests fail;
+- enqueue the same UI command on a replayed pass → exactly-once test fails;
+- remove the hidden UI paint command for injected input → hidden-input test times out;
+- remove an accessible name, or restore `"File ⏵"` as the only label → accessibility/menu tests fail;
+- skip uploads on discard → texture/page test fails;
+- count passes instead of accepted frames → control timing test answers early.
+
+## 9. Performance protocol and thresholds
+
+### 9.1 Measurement identity
+
+Record for every run:
+
+- exact source SHA, lockfile SHA-256, `cargo metadata` package IDs and sources;
+- features (`CRAFT_FONTS_DIR` set/unset, `PDFCRAFT_SYSTEM_FONTS=0/1`, `PDFCRAFT_RENDERER=wgpu/gl`, `monochrome_emoji_fonts`, `clipboard`);
+- fixture hash (`tests/perf.rs::big(500)`, `named_comments(10_000)`, panel fixture);
+- OS/kernel, CPU, RAM, GPU/adapter/driver/backend, DPI/scale, window size (1400×900), renderer, profile;
+- software adapter (llvmpipe/WARP) versus real GPU;
+- host load and concurrent builds.
+
+Baseline is measured **before** any production change, on `a2ec27b`, in its own checkout/target/evidence. Candidate runs use the same machine, boot, fixture and environment. The first report and every investigated regression include stock-0.36 and stock-0.37 controls where the harness can run them, with all three identities recorded.
+
+### 9.2 Harness-first method
+
+The Stage 0 harness must exist on the baseline before PR 1. It has three layers:
+
+1. **Frame/idle/memory**: open the 500-page fixture and named-comment fixture; warm up, then alternating paired runs.
+2. **Targeted engine measurements**: `Context::tessellate` of 120 ASCII labels for #8731; startup phases (instance/adapter/device → pipeline creation → first frame) for #8736 on WARP and a real GPU; font install/discovery with `PDFCRAFT_SYSTEM_FONTS=0/1` and provider enabled/disabled in an isolated fixture for #8512.
+3. **Operations**: open + first frame, zoom, page scroll, dock/float, save/reopen.
+
+Method:
+
+- Build/run only through `maintenance/task.py run/status/finish` with a dedicated task, source and evidence directory; no direct cargo fallback. Submit each build/test directly; do not nest a multi-resource driver.
+- Use release binaries and separate processes for baseline/candidate.
+- At least 20 warm-up frames, 1,000 measured frames per revision for frame distributions; 10 warmups/30 timed iterations for steady operations; 20 fresh processes for startup. Record every raw sample; report median/p95/p99 and sample counts.
+- Alternate baseline/candidate order; use paired runs, separate allocations, no concurrent builds or noisy workloads.
+- Measure idle after settling for 5 s: zero repaints after 3 s, process CPU from `/proc/<pid>/stat` or platform equivalent.
+- Peak RSS from `getrusage(RUSAGE_SELF).ru_maxrss` or `/usr/bin/time -v`.
+- Texture/allocation counters from `FullOutput.textures_delta` and `DocView::receive` upload count/bytes; add test-only counters if needed.
+- Never infer UI performance from compile duration; never auto-update a golden or snapshot.
+
+### 9.3 Predefined thresholds
+
+Relative to the paired baseline on the same machine:
+
+| Metric | Acceptable candidate |
+|---|---|
+| Frame median | ≤ baseline median × 1.05 |
+| Frame p95 | ≤ baseline p95 × 1.10 |
+| Frame p99 | ≤ baseline p99 × 1.15, with at least 1,000 observations |
+| Peak RSS | ≤ baseline × 1.10 |
+| Idle CPU | ≤ 1% of one core; zero repaints after 3 s |
+| Texture bytes/frame | ≤ baseline × 1.05 + 1 MiB |
+| Open + first frame | median ≤ baseline × 1.05; p95 ≤ baseline × 1.10 |
+| Operation latency | median ≤ baseline × 1.05; p95 ≤ baseline × 1.10 |
+
+Noise policy: if baseline median varies by more than 3% across repetitions, discard that run and repeat on a quiet machine; never relax a threshold to make a candidate pass. If a candidate fails, re-run once, then profile before deciding. Existing debug `BUDGET = 40 ms` smoke gates remain; stricter existing budgets win. Use the suite's 0.05 ms floor only for sub-millisecond measurements.
+
+## 10. Quality gates and platform matrix
+
+Required for every PR:
+
+- `cargo fmt --check`
+- `cargo clippy -p pdfcraft-ui-egui -p pdfcraft -p pdfcraft-web --all-targets -- -D warnings`
+- `cargo test -p pdfcraft-ui-egui`
+- `cargo test -p pdfcraft`
+- `cargo check -p pdfcraft-web --target wasm32-unknown-unknown`
+- `cargo xtask layers`
+- `cargo xtask assets`
+- `cargo xtask deny`
+- `cargo xtask parity`
+- `cargo xtask ci` in CI
+- `cargo tree -d`/`cargo metadata` duplicate/source assertions
+- native feature assertion for `egui-winit/clipboard` and `monochrome_emoji_fonts`
+- source-guard evidence from the immutable winit/egui-wgpu revisions
+
+Platform rows:
+
+| Platform | Required evidence |
+|---|---|
+| Linux X11 | real GUI: panels, docking, control screenshot, clipboard, IME (fcitx5/IBus), wheel/zoom |
+| Linux Wayland GNOME | app-drawn frame, window controls, resize edges, panel clipping, PRIMARY |
+| Linux Wayland KDE/Sway | server-side frame, same layout and shortcuts, regular clipboard |
+| Linux Wayland Hyprland | text clipboard/PRIMARY single-device, screenshot control |
+| Windows 11 | real GPU and WARP, mixed-DPI drag, hidden maximized restore, >8192 surface, Korean IME, screenshot, craft-print/GDI build |
+| macOS | traffic lights/title-bar drag, ⌘Q save prompt via craft-quit (W14 not opted in), press-and-hold/dictation IME, emoji picker, Korean space |
+| FreeBSD | CI or explicitly unresolved; no GUI claim without a real session |
+| Web (Chromium/Firefox) | `trunk build`, open a PDF, Arabic UI, shortcuts on a non-Latin layout, image paste, no named-key text leakage |
+
+Headless `egui_kittest` is not proof of native focus, IME, file pickers, clipboard/PRIMARY or GPU presentation. A row is either backed by real evidence or listed as unresolved. Record actual selected test counts and failures; zero selected tests are not acceptance.
+
+## 11. Risks and migration traps
+
+1. **Double bidi.** Adopting E5 while keeping `display_rtl`/`bidi::visual` reverses Arabic/Kurdish twice. Remove preordering in the same language PR.
+2. **Panel keys.** 0.37 derives panel IDs from the parent scope; widths reset unless the first compatibility PR migrates `PanelState`. Child widget state may reset once and is measured.
+3. **`Ui::scope_id` is the old `Ui::id`.** Rename mechanically; do not switch existing `ui.id().with(...)` state to `unique_id()`.
+4. **Multi-pass side effects.** `logic` and `ui` run per pass; edits/undo/render queues must be exactly-once. Do not impose “no commit on discard”.
+5. **Hidden windows and stale input.** `run_logic` leaves input events/time stale. Current input belongs in the UI; background work uses monotonic deadlines.
+6. **E22 pass-index fallacy.** After a completed `run_ui`, `current_pass_index()` is zero; a first-pass guard does not skip ordinary hidden logic. No E22 scheduler API.
+7. **Screenshot assumptions.** A screenshot command itself paints a hidden window; injected input needs `RequestPaintWhileHidden`. Callback completion may be off-thread and has no built-in DPI metadata.
+8. **Texture uploads.** Skipping uploads on `will_discard` can lose first-pass textures. Use generation identity and the final merged delta.
+9. **Kinetic scroll.** Use real `MouseWheelSource` variants; `Unknown` is normal on Wayland/Windows/X11/web. Keep one document glide.
+10. **Font provider policy.** eframe's system-font provider can read many installed faces, including proprietary ones; keep it off and preserve `PDFCRAFT_SYSTEM_FONTS=0`.
+11. **Default-font glyph loss.** 0.37 gates emoji fonts; enable `monochrome_emoji_fonts`, add `egui-icons.ttf`, and keep the kittest glyph panic.
+12. **Kittest stricter accessibility.** Unnamed inputs fail; fix labels rather than disabling checks.
+13. **`WidgetType::TextEdit` does not exist as a `Role`.** It is `Role::TextInput`; `Checkbox` is `Role::CheckBox`.
+14. **craft-print drift.** The bump adds `craft-winprint-gdi`, `rgb`, `lpstat -l` descriptions and `Printer.description`; audit all, fix 19 literals and preserve current main's security fixes.
+15. **Winit source guards.** Twelve app modules read old vendor paths; move them centrally and use exact git identities.
+16. **Snapshot churn is not acceptance.** Review every diff and keep semantic pixel tests.
+17. **PRIMARY.** W15P is required and is present in the current winit pin; filtering `MiddleClickPaste` does not avoid the protocol risk and is not the selected design.
+18. **IME surrounding text.** The planning-era candidate lacked E21b/P7b; pinned `6d518fc` contains the producer. Native Wayland execution remains unqualified, so do not describe W27 as complete integration.
+
+## 12. Resolved decisions and external gates
+
+Decisions made by this plan:
+
+- **E11:** not required by PdfCraft; epaint's `vello_cpu` 0.2.0 cannot unify with hayro's 0.0.8. Verify with `cargo tree -e features -i vello_cpu`.
+- **Kinetic scrolling:** PdfCraft's `fling.rs` owns document motion; ordinary widget `ScrollArea`s keep egui's kinetic default. Use `Unknown`/`Wheel`/`Trackpad`/`Momentum`; macOS custom fling is off.
+- **Panels:** migrate persisted `PanelState` keys in PR 1; transient in-panel focus/scroll may reset once only if the upgrade test proves it.
+- **PRIMARY:** adopt W15P on the existing winit connection/event queue; no app-level filtering and no second regular data device.
+- **RTL:** remove catalog preordering; explicit `TextDirection` for UI labels; `Style::right_to_left` after manual-layout audit; explicit craft-ui dock direction; saved workspace order unchanged.
+- **Fonts:** `monochrome_emoji_fonts` on; no broad system provider.
+- **Window frame:** `craft_window::Choice` at startup; `PDFCRAFT_TITLEBAR=app|system|desktop`; `window_controls` uses craft-window types; runtime preference remains a `ViewportCommand::Decorations` toggle.
+- **Screenshot helper:** PR 1 waits for and directly adopts the reviewed craft-ui helper after CL-2F; no local duplicate.
+- **Performance:** harness and baseline precede production; stock-0.37 control accompanies first baseline and regressions.
+
+External gates that cannot be decided from this host:
+
+- final approved immutable storytold egui/winit/craft-libs revisions, including W15P and E21b/P7b;
+- native Wayland PRIMARY/IME evidence on wlroots/KWin/Mutter;
+- Windows real-GPU/WARP and native GUI evidence; macOS and FreeBSD hardware evidence;
+- browser runtime and non-Latin keyboard evidence;
+- explicit human approval of every branch/tag push, PR or publication.
+
+## 13. Limitations of this plan
+
+- No build, test, clippy, fmt, wasm, GUI or performance run was performed. The current tree was read only.
+- No compiler diagnostics were generated for this baseline. Historical audit diagnostics are stale.
+- Upstream status comes from the provided `upstream-discussions.json` snapshot and local refs; it is not a live GitHub query. #8763 and #8764 are an open issue/PR, not release fixes. #8748 is closed and N/A because PdfCraft uses only `ViewportId::ROOT`.
+- No native Wayland compositor, macOS or Windows session was available; PRIMARY, IME, focus and real-GPU behavior remain unverified.
+- No performance baseline has been measured. The thresholds in §9 are predeclared relative limits; the absolute baseline must be recorded before implementation.
+- The exact publication revisions for egui, winit and craft-libs remain external prerequisites, not user choices.
+- Only `docs/egui-037-migration-plan.md` was written. No production file, manifest, lockfile, vendor tree or test was changed.
+
+## 14. Source index used for this plan
+
+PdfCraft:

+
+
+## Local implementation update — 2026-10-23
+
+The user clarified that reviewed plans remain local and implementation proceeds before publication. The earlier requirement to publish/land this plan first is superseded; pushes and PR publication still require explicit approval.
+
+The owned checkout now HEADs at `a2ec27b4775f53c40cad3456936d9406611e3a8d`; `57e531ccca0047597809748b5cb4276336d6051a` and the earlier baseline SHAs above remain historical review evidence, and both refs remain reachable. Current integration uses this checkout and its qualification lock; paired measurements must record the exact source and lock they used.
+
+Preserve document-folder native dialogs, colour popup close policy, panel-header spacing, bookmark contrast, and org_drag cancellation after document changes. Preserve new integration regressions and generate fresh baseline geometry.
+
+The complete static delta review and exact old/new object identities are retained in the task evidence: `canonical-diffs-refresh-20261023.json` and `overnight-consumer-review-20261023.md`. This amendment claims no new build, native GUI or performance acceptance.
+
+## Local implementation amendment — 2026-10-24
+
+**Historical note (superseded by the 2026-10-25 qualification state).** The migration is implemented locally but remains unpublished. At the time of this amendment, `egui`/`eframe`/`egui-wgpu` 0.37.0, the reviewed winit worktree and the shared craft-libs helpers resolved through `local-integration-config.toml`; the checked-in `Cargo.toml`/`Cargo.lock` did not yet pin them. The current tree pins egui `6d518fc`, winit `a517b38` and craft-libs `25da131` (craft-ui, craft-quit and craft-print) directly, while `craft-docpath` remains at `82a24b006eefa036b43c09a67fb9a3fbd17ffe63` (see the top section). The repository quality gates passed as recorded below; publication still requires fresh human approval. No push, PR or release is authorized by this amendment.
+
+The font contract now includes the native-only Simplified Chinese face: the pinned craft-fonts input supplies `fonts/simplified-chinese-manifest.txt` (LXGW WenKai Lite, OFL-1.1), `crates/fonts/build.rs` embeds it on native builds only under a 16 MiB cap, and a `CRAFT_FONTS_REQUIRED` build fails rather than skipping an absent or over-cap required Chinese face. Traditional Chinese is served by an installed `Hant` face placed before the Japanese faces even when LXGW is embedded. CI, release and FreeBSD keep an immutable craft-fonts commit pin; the current candidate is recorded in the task evidence and the pin must be updated only to a published central commit.
+
+Fallback faces now use egui 0.37's `FontTweak::fallback_align = FallbackAlign::Baseline` for the existing one-baseline intent (the metric-derived `y_offset_factor` compensation is gone). Control-channel synthetic input that times out after a press keeps one bounded release batch, so a key, pointer button or modifier cannot stay held when the window resumes. Accepted-frame counting remains one count per presented frame, verified at `max_passes` above two.

 | 2026-10-21 | minor | Brazilian Portuguese (`pt-br`) now covers all 2,674 distinct keys in the current catalog union; no help or engine/OS error-detail localization; twelve-language mean still rounds to ≈ 68% |
 | 2026-10-20 | minor | Spanish: the 143 keys the other catalogs had and `es.tsv` was missing; `es` now covers the whole 2,674-key union, like `lt` and `vi`. Restated Lithuanian against the current union (its 2,585 was measured on 2026-10-13) and said plainly in *How this was measured* that the union moves, so counts only compare within a date |

The change applies immediately and persists between launches. Command ids, document contents and file names are unchanged.
 
 Displayed keyboard shortcuts use the same active interface language. For example, German shows `Strg+K` and `Strg+Umschalt+S` in the toolbar, menus, command palette, tooltips and Keyboard shortcuts dialog; macOS keeps its modifier symbols (`⌘`, `⇧`, `⌃`). Key names have their own `key` catalog context, so the Delete key can read `Entf` while the command remains `Löschen`. A missing key-name entry falls back to the English key name. Actual bindings and machine-facing command ids remain stable.
 
-**Auto** (the default) follows the system language: `LC_ALL`, `LC_MESSAGES` or `LANG`, then the preferred-languages list on macOS. Any Portuguese locale (`pt_BR`, `pt_PT`) uses the Brazilian catalog, any French locale (`fr`, `fr_FR`, `fr_CA`, `fr_BE`) the French one, any German locale (`de`, `de_DE`, `de_AT`, `de_CH`) the German one, and Chinese locales for Taiwan, Hong Kong and Macau (`zh_TW`, `zh_HK`, `zh_MO`, `zh-Hant`) the Traditional Chinese one; other Chinese locales (`zh`, `zh_CN`, `zh_SG`, `zh-Hans`) the Simplified Chinese one. Telugu locales (`te`, `te_IN`) use the Telugu catalog, Bulgarian locales (`bg`, `bg_BG`) the Bulgarian one, and Hungarian locales (`hu`, `hu_HU`) the Hungarian one, and Ukrainian locales (`uk`, `uk_UA`) the Ukrainian one, and Italian locales (`it`, `it_IT`, `it_CH`) the Italian one, and Arabic locales (`ar`, `ar_MA`, `ar_EG`, `ar_SA`, …) the Arabic one, and Turkish locales (`tr`, `tr_TR`) the Turkish one, and Slovenian locales (`sl`, `sl_SI`) the Slovenian one, Vietnamese locales (`vi`, `vi_VN`) the Vietnamese one, Albanian locales (`sq`, `sq_AL`, `sq_XK`, …) the Albanian one, Catalan locales (`ca`, `ca_ES`, `ca_AD`, `ca_ES@valencia`, …) the Catalan one, and Romanian locales (`ro`, `ro_RO`, `ro-RO`, `ro_MD`) the Romanian one. Norwegian Bokmål locales (`nb`, `nb_NO`) use the Bokmål catalog, and so do general Norwegian (`no`, `no_NO`) and Nynorsk (`nn`, `nn_NO`), which have no catalog of their own. A system language without a catalog shows English. On Windows, **Auto** uses the Windows display languages, in preference order, when no supported locale is selected by those environment variables. Neutral `C`/`POSIX` locale values (including `C.UTF-8`) inherited from a launcher do not override the Windows display language; explicitly named supported locales such as `fr_FR.UTF-8` still do. The query asks Windows directly (`GetUserPreferredUILanguages`, through the `sys-locale` crate) without starting a process, and is cached for the process. If detection fails or the display language has no catalog, PdfCraft shows English.

Telugu locales (`te`, `te_IN`) use the Telugu catalog, Bulgarian locales (`bg`, `bg_BG`) the Bulgarian one, and Hungarian locales (`hu`, `hu_HU`) the Hungarian one, and Ukrainian locales (`uk`, `uk_UA`) the Ukrainian one, and Italian locales (`it`, `it_IT`, `it_CH`) the Italian one, and Arabic locales (`ar`, `ar_MA`, `ar_EG`, `ar_SA`, …) the Arabic one, and Turkish locales (`tr`, `tr_TR`) the Turkish one, and Slovenian locales (`sl`, `sl_SI`) the Slovenian one, Vietnamese locales (`vi`, `vi_VN`) the Vietnamese one, Albanian locales (`sq`, `sq_AL`, `sq_XK`, …) the Albanian one, Catalan locales (`ca`, `ca_ES`, `ca_AD`, `ca_ES@valencia`, …) the Catalan one, and Romanian locales (`ro`, `ro_RO`, `ro-RO`, `ro_MD`) the Romanian one, and Persian locales (`fa`, `fa_IR`, `fa_IR.UTF-8`, `fa-AF`, ...) the Persian one. Norwegian Bokmål locales (`nb`, `nb_NO`) use the Bokmål catalog, and so do general Norwegian (`no`, `no_NO`) and Nynorsk (`nn`, `nn_NO`), which have no catalog of their own. A system language without a catalog shows English. On Windows, **Auto** uses the Windows display languages, in preference order, when no supported locale is selected by those environment variables. Neutral `C`/`POSIX` locale values (including `C.UTF-8`) inherited from a launcher do not override the Windows display language; explicitly named supported locales such as `fr_FR.UTF-8` still do. The query asks Windows directly (`GetUserPreferredUILanguages`, through the `sys-locale` crate) without starting a process, and is cached for the process. If detection fails or the display language has no catalog, PdfCraft shows English.

-Edit text reads Hebrew lines in typing order and writes them back in drawing order (`crates/edit/src/bidi.rs`); letters the page's own font lacks are drawn with the craft-fonts `Hebr` face (Noto Sans Hebrew) as Type 3 glyphs, and a build without one says so.

Add text (#128) draws Hebrew with the same face through the shaped path Arabic and Thai use: right to left with numbers and Latin in place, points kept on their letter, and typing order for copy and search. The craft-fonts revision pinned for CI and releases has no `Hebr` face yet, so until one is added releases report that error instead of drawing the missing letters, and refuse Hebrew in Add text.

-Japanese interface text uses BIZ UDPGothic from [craft-fonts](https://github.com/storytold/craft-fonts), an optional build input that every release includes (`CRAFT_FONTS_DIR`; see the README). A build made without it has no Japanese face, so Japanese labels show replacement boxes. Chinese is drawn with the same craft-fonts CJK faces (in Simplified Chinese the `Hans` faces come first, so a line never mixes faces with different baselines), so a character none of them has shows a replacement box (and every Chinese character does in a build without craft-fonts). Until craft-fonts has an allowed `Hans` face, the desktop app draws a Chinese interface with a Chinese face already installed on the machine (Microsoft YaHei or JhengHei on Windows, PingFang, Hiragino Sans GB or STHeiti on macOS, WenQuanYi or Droid Sans Fallback on Linux; never Noto CJK or Source Han), placed before the Japanese faces so a line keeps one face (#826). The web build has no installed fonts to fall back on. Russian, Bulgarian, Czech, Brazilian Portuguese, German, Spanish, French, Hungarian, Italian, Slovenian, Turkish, Lithuanian, Norwegian, Finnish, Albanian, Catalan and Romanian need only the bundled Latin faces (tested in `tests/fonts.rs`). Slovenian has four plural forms: one (1, 101, 201…), two (2, 102…), few (3, 4, 103…) and other (everything else, including 0, 5–20 and 21+), so `@plural` entries list four forms (`1 stran`, `2 strani`, `3 strani`, `5 strani`). Hungarian uses the same one/other plural rule as English: 1 is singular, and every other count — including 0 — is the other form. After a numeral the noun stays singular (`1 oldal`, `2 oldal`). Telugu is drawn with a craft-fonts `Telu` face (Noto Sans Telugu, kept in the web build too), whose conjuncts egui shapes; a build without one shows Telugu labels as replacement boxes, and the release-pinned craft-fonts input has no Telugu face yet.

On native builds, `fonts/simplified-chinese-manifest.txt` adds LXGW WenKai Lite as a `Hans` face (at most 16 MiB, never embedded on the web); Simplified Chinese puts the `Hans` faces first, so a line never mixes faces with different baselines. Traditional Chinese has no embedded `Hant` face: the desktop app places a Traditional Chinese face already installed on the machine (Microsoft JhengHei on Windows, PingFang TC on macOS, a Noto CJK TC or WenQuanYi Zen Hei on Linux) before the Japanese faces, even when LXGW is bundled, because a Simplified-only face cannot supply Traditional-only characters. Without an embedded `Hans` face, Simplified Chinese likewise uses an installed Simplified Chinese face (Microsoft YaHei, PingFang SC, …) placed before Japanese (#826). The web build has no installed fonts to fall back on, so it shows a replacement box for characters the Japanese face lacks.

 The Albanian catalog (`sq.tsv`, interface name **Shqip**) is written in Standard Albanian with the imperative for commands (`Ruaj`, `Hap`, `Fshi`).

 ## Arabic and right-to-left text
 
-The Arabic catalog has 2,137 entries in Modern Standard Arabic with Western digits. Counts use the six [CLDR Arabic forms](https://www.unicode.org/cldr/charts/48/supplemental/language_plural_rules.html#ar) (`0`, `1`, `2`, `3–10`, `11–99`, the rest), and dates use the Arabic names of the Gregorian months.

-egui joins the letters of an Arabic word and runs them right to left, but it places the words of a line left to right in the order they are written. So catalog entries are written in logical (typing) order, and `i18n` puts each one into display order when the catalog loads (`bidi::display_rtl`): the line reads right to left, Latin words and numbers inside it read left to right, `{name}` placeholders and keyboard shortcuts stay whole, spaces at either end stay where the code concatenates, and a short caption keeps its colon on the right, beside the widget it captions. Lookups (`tl!`, `tr`, `trn`) therefore return display-order text for Arabic; `i18n::fmt` inserts values as they are. The command search matches a query of several Arabic words word by word.
+egui 0.37's epaint shapes every line with the Unicode bidirectional algorithm (UAX #9). Catalog entries stay in logical (typing) order and are never preordered: `tl!`, `tr` and `trn` return logical text, `bidi::display_rtl` and `bidi::visual` exist only for the tests that prove the old preordering is gone, and epaint joins and reorders Arabic on every line. Interface labels use an explicit `TextDirection::RightToLeft` in an Arabic, Kurdish or Persian interface, so a label whose first strong character is Latin or a `{placeholder}` still reads right to left. File and path labels use `TextDirection::LeftToRight`, so an Arabic file name keeps `.pdf` at its visual end; document-authored text uses `Auto`. Stock chrome is mirrored through `Style::right_to_left` (menus, combo boxes, scroll bars, headers), and `i18n::fmt` inserts values in one pass. The command search matches a query of several Arabic words word by word.
 
-What Arabic does not have yet:
+Wrapped paragraphs break between words in logical order and epaint reorders each resulting line, so a wrapped label reads in the right direction from the first line down. Text typed into a field is shaped and reordered while editing, and the stored value stays logical.
 
-- **The layout is not mirrored.** Panels, menus, toolbars and alignment are as in the left-to-right languages, with Arabic labels in them.
-- **A wrapped paragraph breaks at the wrong end.** A label too long for its line continues on the next line with its *first* words, so wrapped descriptions and tooltips read from the last line up. Single-line labels are right.
-- **Text you type into a field** (search, comments, form values) has joined letters but its words run left to right while you edit it. What is stored is correct.
-- Labels built by joining translated pieces in code (a list such as `A · B · C`) keep the code's left-to-right order.
+Central Kurdish (Sorani, `ckb`) takes the same path: its catalog is written in logical order and `rtl: true` selects the explicit right-to-left direction; epaint reorders it, so it behaves as Arabic does above. Counts use the two [CLDR ckb forms](https://www.unicode.org/cldr/charts/48/supplemental/language_plural_rules.html#ckb) (`one`, `other`); Sorani keeps the noun singular after a numeral, so the two `@plural` forms usually read the same. Dates use the Kurdish names of the Gregorian months. The `Arab` face (Noto Sans Arabic) covers the Kurdish-only letters (`ێ ڵ ڕ ۆ ە ڤ ژ چ گ پ`).
 
-These need bidirectional support in the text layout itself, not in the catalog.
+The Persian catalog (`fa.tsv`, interface name **فارسی**) has 2,785 entries, covering 2,785 of the current 2,798-key union; the 13 keys added after it was written still show English. It is written in contemporary software Persian from the meaning of the English labels. Counts use the two [CLDR `fa`](https://www.unicode.org/cldr/charts/48/supplemental/language_plural_rules.html#fa) forms (`one` for 0 and 1, `other` for every other count), so `@plural` entries list two forms. It is right to left like Arabic and Kurdish: `rtl: true` selects the explicit right-to-left direction, the entries stay in logical order and epaint reorders each line, and the stock chrome is mirrored as it is for Arabic. Compound words use the zero-width non-joiner (نیم‌فاصله, U+200C), the Persian comma `،` and question mark `؟`, and Persian `ی`/`ک` rather than the Arabic `ي`/`ك`. Dates use the Persian names of the Gregorian months. The `Arab` face (Noto Sans Arabic) covers Persian letters, so it needs no Japanese face. The translation is AI-assisted and has not yet been proofread line by line by a native speaker; status `partial`: no translated help, and engine/OS error details stay English inside a translated frame.
 
-Central Kurdish (Sorani, `ckb`) takes the same path: its catalog is written in logical order and `rtl: true` puts every entry into display order at load (`bidi::display_rtl`), so it behaves as Arabic does above and has the same four limits. Counts use the two [CLDR ckb forms](https://www.unicode.org/cldr/charts/48/supplemental/language_plural_rules.html#ckb) (`one`, `other`); Sorani keeps the noun singular after a numeral, so the two `@plural` forms usually read the same. Dates use the Kurdish names of the Gregorian months. The `Arab` face (Noto Sans Arabic) covers the Kurdish-only letters (`ێ ڵ ڕ ۆ ە ڤ ژ چ گ پ`).
+Arabic glyphs come from the craft-fonts `Arab` face (Noto Sans Arabic, kept in the web build too). A build without craft-fonts shows Arabic as replacement boxes on the web; on desktop it falls back to one installed font (below). The craft-fonts revision pinned for CI and releases (`.github/workflows/`) has the Arabic and Hebrew faces. Its Noto Sans CJK SC face is 16.4 MB and is left out by the general CJK cap; native builds take the separately pinned Simplified Chinese face (LXGW WenKai Lite) from `fonts/simplified-chinese-manifest.txt`, and the web build embeds only BIZ UDPGothic Regular plus the small Arabic, Hebrew, Thai and Devanagari faces.

That revision also holds Noto Sans CJK SC, which `crates/fonts/build.rs` never embeds: `AGENTS.md` §1.1 bars it, so Chinese still has no embedded face of its own (desktop builds fall back to an installed Chinese face, above).
+File names and document titles use the craft-fonts `Arab` face (Noto Sans Arabic) for Arabic and the `Hebr` face (Noto Sans Hebrew) for Hebrew when those faces are included in the build input; on desktop, a character no embedded face has is drawn with one font already installed on the machine (`PDFCRAFT_SYSTEM_FONTS=0` turns this off). epaint reorders each line with UAX #9, while file and path labels keep an explicit left-to-right base so the extension stays at the visual end; the tab strip, the recent-files list and Properties show such names in display order.

-Japanese, Simplified Chinese, French, German and Brazilian Portuguese coverage tests, following PhotoCraft's complete-catalog approach, check every registered command, All tools label and `tl!("literal")` in the UI source. Brazilian Portuguese also checks every key in the union of the bundled catalogs. Simplified Chinese additionally checks direct `i18n::t` calls and multiline literals, plus the About tabs, contributor name modes, sort options, table headers and model columns. Generated history labels, contributor summaries and diagnostics are tested with user-supplied names and error details. Catalog coverage does not guarantee glyph coverage: the release-pinned craft-fonts input currently has no `Hans` face, and the web build embeds only BIZ UDPGothic Regular. Chinese font delivery remains separate work, as discussed in [#112](https://github.com/storytold/pdfcraft/pull/112) and [#140](https://github.com/storytold/pdfcraft/pull/140).
+Catalog coverage does not guarantee glyph coverage. Native builds embed LXGW WenKai Lite as the Simplified Chinese face from the pinned craft-fonts input (at most 16 MiB), while the web build embeds only BIZ UDPGothic Regular plus the small Arabic, Hebrew, Thai and Devanagari faces, so Chinese characters none of those faces has show replacement boxes on the web. Traditional Chinese has no embedded face and uses a `Hant` face installed on the machine, placed before the Japanese faces even when LXGW is bundled.
 
 German labels keep nouns capitalized, including tool names inserted into notices. The certificate viewer uses the `certificate` context for `Subject` (the certificate holder), while document properties keep the plain translation (the topic). Search hints reserve room for the shortcut, and Home cards limit their title and description to the available rows; hovering shows the full text when it is shortened.
 
@@ -72,8 +67,9 @@ PdfCraft uses the same system as PhotoCraft (`crates/ui-egui/src/i18n/`):
 - Strings in the code stay in English and serve as lookup keys. At draw time, `tl!("Save")` returns the text in the current language, and falls back to English when there is no entry.
 - Each language has a catalog, `crates/ui-egui/src/i18n/<code>.tsv`, with one entry per line: `context<TAB>English<TAB>translation`. An empty context marks a plain string. `@id` keys an entry by command id (for example `file.saveAs`), so one menu item can read differently from another with the same English label. `@plural` holds plural forms. Any other context disambiguates an English word with several meanings (`tl_ctx!` in UI code, for example the signature pad's "Type" button against the "Type" column). The header of `ja.tsv` documents the format and escapes.
 - Placeholders (`{name}`) must appear in both columns. A trailing `…` must be kept. `i18n::fmt` fills placeholders in one pass, so a value such as a file name containing `{n}` is inserted as written.
+- A missing entry never fails a build or a test: that string shows in English. `cargo xtask i18n-report`, a step of `cargo xtask ci`, prints for each language how many strings it has no translation for and the first few. It counts every command, All tools label, literal passed to `tl!` or `i18n::t` in the UI source, engine wording (below) and key of the bundled catalogs, so a new English string shows up there until each catalog has it.
 - Catalogs are validated strictly: unknown escapes, unknown `@` contexts, placeholder or ellipsis mismatches, wrong plural form counts and duplicates are errors. The tests require the bundled catalogs to have none; at run time a bad line is skipped (and logged) and that string shows in English.
-- Catalogs are assets: each `.tsv` has an `ATTRIBUTION.toml` entry with `kind = "translation"` and its SHA-256, checked by `cargo xtask assets`. After editing a catalog, put the new hash into its entry by hand (`sha256sum crates/ui-egui/src/i18n/<code>.tsv`), because `cargo xtask assets --write` does not touch `ATTRIBUTION.toml`; the hash check is deliberate, so a changed asset gets its provenance re-checked. Without it `cargo xtask assets` and the test `assets::tests::the_real_manifest_passes` fail.
+- Each `.tsv` has an `ATTRIBUTION.toml` entry with `kind = "translation"` (title, author, source, licence), checked by `cargo xtask assets`. Catalogs are project files under the project licence, so the entry has no `sha256` and editing a catalog doesn't touch `ATTRIBUTION.toml`; git history records their provenance.

 - `said(&words)` says one of them: the layer looks its own wording up through the closure it is given, then fills the holes with the document's values — a page number, a font name, what the person typed — in one pass, so a value containing `{n}` is inserted as written.
 - The UI passes `&crate::i18n::words`, which is a catalog lookup, so the sentence reads in the interface language. `in_english` is the same thing in English, and a wording with no entry comes back as it stands, which is the English — a catalog missing one shows an English sentence rather than a gap.
 - The lists are `a11y::{WORDINGS, REPORT_WORDS}`, `preflight::WORDINGS`, `sign::pdf::{WORDINGS, kind::ALL}`, `print::WORDINGS` and the engine's `{EDIT_LABELS, BATCH_LABELS}`. `a11y::report_html` takes a language tag and a `words` closure, so a saved report reads the way the panel read, down to its `lang` attribute.
-- `spanish_covers_what_the_engine_says` requires an entry for every wording in those lists, and `spanish_keeps_the_holes_in_what_the_engine_says` requires each translation to keep the same holes, so the catalog cannot fall behind the engine without a test saying so. Other languages are free to add the entries when they are translated; until then those sentences show in English as before.
+- The translation gaps report (`cargo xtask i18n-report`) counts every wording in those lists, so a catalog that lacks one shows there; until it is added, that sentence shows in English.

+| M8 | Security + redaction | 100–180 | 68% | 15–30 | Done: opening protected documents, permissions, Protect Using Password, Remove security; redaction (mark text/areas/pages, Search & Redact with patterns, apply removing glyphs, image pixels, vectors, XObject content, annotations and fields, verification, full rewrite on save); Remove hidden information and Sanitize.<br>Done since: redaction codes (U.S. FOIA and Privacy Act sets as overlay text, in Redaction properties and `redact_mark`). Redaction cleans indirect and form structure references, preserving surviving form tags. Redaction retires inherited resource dictionaries, so a parent `/Pages` can't keep a removed XObject reachable; unredacted pages are left untouched. Image redaction removes alternate images and unsupported masks only on affected images. Changed marked-content spans lose replacement descriptions; untouched spans keep theirs. Hidden-text cleanup retires unused named descriptions across inherited/shared page and form resources (64 focused tests and scoped Rust 1.96 Clippy/wasm checks pass; publication CI pending). The redaction audit counts a filled cover that hides half of any one word of a long line (#2662), applied or not. Phone-pattern redaction also matches labelled Italian geographic numbers with `+39` and a slash after the area code (#3205 follow-up); unlabelled international slash numbers remain unsupported.

 ## Revision history
 
+**2026-10-25 · minor:** M14 localization current state: Arabic catalogs stay logical, Arabic/Kurdish labels take an explicit RTL direction, and stock chrome mirrors; native/browser RTL input, IME and complex workflows remain unqualified. Native Simplified Chinese uses LXGW WenKai Lite; the web build has no Hans face. Estimates unchanged.
+
+**2026-10-23 · minor:** M11: image downsampling uses physical resolution after page-local `/UserUnit` scaling, including shared nested forms.
+Synthetic measurement and optimization regressions cover the change.
+Estimates unchanged.
+
 **2026-10-20 · minor:** M2/#3601: substitute-font spacing aliases preserve blank ink, original `/W` and `/DW` advances, and Unicode extraction. Synthetic renderer regressions cover the reported Japanese CID fixture. Estimates unchanged.
 
 **2026-10-15 · minor:** M14/#2383 candidate: GPU device requests clamp unsupported limits while retaining the adapter texture extent. Synthetic V3D/downlevel regressions and Windows GPU-required tests pass; Raspberry Pi hardware remains unverified. Estimates unchanged.

+| 2026-10-24 | minor | M3, #3970 follow-up: the button release given back after a window move or resize goes before the pointer leaving, so hover doesn't stick. Estimates unchanged. |
+| 2026-10-23 | minor | M8, #3205 follow-up: phone-pattern redaction includes the +39 country code on labelled Italian geographic numbers with a slash; dates, protocol identifiers and whole-run guards remain. Estimates unchanged. |

+| 2026-10-23 | minor | M10: covered table slots retain their text in paragraph flow across Office exporters; emitted superscripts remain in their cells. Synthetic source and CLI regressions; estimates unchanged. |
+| 2026-10-23 | minor | M10: Export all images and Save Image As apply soft-mask Decode intervals to PNG alpha before resizing, including inverted/subrange, indirect, packed and JPEG masks. Estimates unchanged. |
+| 2026-10-23 | minor | M10: annotation appearances use unoccupied XObject names, preserving original page artwork and distinct appearances through inherited resources and print/reopen. Estimates unchanged. |
+| 2026-10-21 | minor | M3: on GNOME/Wayland, a second resize by an edge or move by the tab strip works without a click in between (the compositor kept the button's release from egui). Estimates unchanged. |
+| 2026-10-22 | minor | M4, #3916 partial: edits and Undo/Redo cancel Organize page drags. Pointer-release and save/reopen regressions check page order. Estimates unchanged. |
+| 2026-10-22 | minor | M14 #3558: rebased macOS association recovery; reuse #3042 shared metadata preservation instead of a duplicate save wrapper. Estimates unchanged. |
 | 2026-10-20 | minor | M4: initial-view window and interface options resolve indirect boolean ViewerPreferences values; synthetic true/false and save/reopen regressions retain defaults for malformed entries. Estimates unchanged. |
 | 2026-10-21 | minor | M3, #3808: the Pages inspector has an independent 50–150% thumbnail size slider and buttons; selection and current-page following are retained, with headless ui.set coverage. Estimates unchanged. |

 | 2026-10-17 | minor | M8, gap 6 #2662: a filled cover that hides half of any one word of a long line counts as a redaction-audit finding, applied or not; a sliver under half of every word stays unflagged. Estimates unchanged. |

+| 2026-10-22 | minor | M6: calculation scripts: simplified field notation is read only from a comment, and a regular expression after `if (…)`, `while (…)`, `for (…)` or `with (…)` as one, so a rename leaves strings and regular expressions alone; a `//` comment ends at any line terminator, not only `\n`.

Edit ▸ Column select does the same with a plain drag. A glyph counts when its centre is inside. Copy gives one row per visual line, top to bottom; pieces side by side (table cells) are separated by a tab, right to left in right-to-left rows; vertical text keeps reading order. text_extract takes the same rectangle as rect. Platforms: on Linux desktops whose window manager moves windows with Alt-drag (Xfce, Cinnamon and MATE by default; KDE Plasma 5 and other setups with Alt as the window modifier; GNOME and Plasma 6 use Super) the drag never reaches PdfCraft, so use Edit ▸ Column select or change that setting. On Windows, releasing Alt does not open a system menu (the window has no native menu). The web build has the same Linux caveat in the browser. Checked by hand on Linux (Fedora) with the Column select tool; Alt/Option-drag, and macOS and Windows generally, rest on the kittest tests.

Problems show before Combine (password, security settings that withhold page assembly, bad page ranges, duplicates); protected files are unlocked with their open or permissions password (also doc_combine passwords). The result is never encrypted, and is not yet offered for protection in the same step.

 notes = "Combine files shows a card per file (the default; Grid/List toggle kept in the settings, --combine-view grid|list): the first page the file contributes (its page range's first page), stacked when it contributes more, and its name shortened in the middle. Cards are sized from 60% to 500% (toolbar slider, buttons and percentage reset, Ctrl/⌘ +/−/0, Ctrl/⌘ with the wheel or a pinch over the grid; the buttons step 60/80/100/125/150/175/200/250/300/400/500%, kept in the settings, --combine-zoom 60..500), keeping the card under the pointer in place. 200% used to be the ceiling, which was too small to read values off an invoice while reordering the pages of a statement (#2531). Hovering a card shows its own actions along the top of its page: remove that file only (whatever else is selected; undoable) and a magnifier that shows the file large, flipping through the pages it adds (buttons, Left/Right; Esc, close or a click outside closes it), also on the card's right-click menu, and Space shows the selected file large (the way there by keyboard). Cards select (click, Ctrl, Shift, arrows by card and by row), drag to reorder (one undo step; the grid scrolls at its edges) and share the list's toolbar. Thumbnails render off the UI thread, only for cards in view, sized to both sides of the page and at most 1536 px (room for a Letter page at 500% on a 1.5 pixels-per-point screen); at most three render threads at once, counted as threads until they exit (no watchdog replacements; a page stuck for good in one step that can't be interrupted keeps its thread, and so its place, for the rest of the run); textures out of view are dropped over a 32 MB budget (those in view are kept). Locked, unreadable and bad-range files show why instead of a page, and a file whose page size can't be read (e.g. opened with an RC4 owner password) says No preview; page ranges are edited in the list. On the web a thumbnail, and the page shown large, render on the UI thread (one per frame, and only one waits at a time), so a very slow or very large page stalls that frame. A file that adds more than one page (up to 2000) expands into its pages (hover bar, right-click, or Expand all / Collapse all in the toolbar): one card per page it adds, in its range's order, each saying Page N and the file's name, on a tinted band; a click on a page selects that page, Up/Down step rows of cards, dragging a file's card moves the whole file (a drop among a file's pages goes to its nearer end), and its magnifier opens the preview on that page; expanding is a view, not an undo step, and changes nothing in the combined file; a page's render reuses its file's open document for a moment rather than reading the file again. With a file expanded, single pages are selected (click, Ctrl, Shift), dragged anywhere (a page moved between another file's pages splits its file into parts, shown as rows in the list with their own page ranges; parts side by side join again) and removed (a page card's trash, the toolbar, Delete), each one undo step, never changing the files themselves; a split file still counts and combines as one file."

Scanned pages (an image covers at least half the page and the content draws no lines) are rendered and their rules, boxes and check boxes read from the pixels; a box with a small printed label gets a field in its empty part. Detected fields get no border and no fill, since the page already draws the line or box they sit on; fields drawn by hand keep the grey border and white fill. Tested on synthetic scans only: straight, stored sideways with /Rotate 90 (fields get /MK /R so typing reads upright), noisy, and 1 degree askew (fields stay inside their boxes but lose up to the skew in height). Labels come from the text layer or, when the OCR models are installed, from text recognition (Latin without accents, so German labels with umlauts make poorer names); without either, fields get default names (Text1, Check Box1). Recognition runs synchronously, about a second per scanned page. Not yet: dotted leader lines, tables of cells as such, deskewing, radio groups."

Repeated page-master buttons resolve their own PDF field to the shared XFA click script; the numPages-based print script requests printing from every copy, including after save/reopen (#2572). Rich-text exData/maxLength is carried into AcroForm MaxLen, reported by form_fields and enforced by form_fill (Unicode characters); limits and accepted values survive save/reopen (#2570). laid out from the template on open by the xfa crate (positioned, tb, lr-tb, table/row, page masters (a page area with no occur repeats without limit, one with occur max=1 is used once, one with occur min=1 the body never reached gets a page after the body, as Acrobat Pro does on a synthetic form), breaks, repeated header rows, captions, rich text, JPEG/PNG/GIF/BMP/TIFF images) into real pages and AcroForm fields (text, password, date with AFDate formats, check boxes, radio groups, drop-downs and list boxes with shown/saved item pairs and multi-select, signature fields, image fields showing their picture (pictures decoded once per document, at most 20 million pixels, and reused across re-layouts), buttons with reset/print/save/URL), filled from the datasets packet (including rows another viewer added), saved as an incremental revision with the values merged into the datasets so Adobe's viewers show them; doc_info reports xfa_layout. CLI info reports the laid-out page/field counts and dimensions while retaining the input file size and raw counts as pdf_pages/acroform_fields; text and render use those pages too, preserving copy permissions and leaving the source file unchanged (#1645). XFA JavaScript and FormCalc (form.xfa-formcalc) run in the js crate's XFA object model (xfa.form, SOM resolution, rawValue, formattedValue in a date display picture's pattern (number and text display pictures still give the raw value), presence, access, instance managers, xfa.host, xfa.layout, xfa.event): initialize and calculate on open, exit, validate and calculate after a field changes, click for buttons (through js_run and the app), with rows added and removed, subforms shown and hidden, and the form laid out again, all as one undo step and kept in the file. All the scripts of one event run on one thread, each in a fresh context on the form as the engine holds it then (nothing shared between scripts; the live form kept up to date in place for values, rebuilt only when the structure changed), so hundreds of calculations run within the open budget. Hostile scripts are bounded per event (merged and capped effects, messages and console lines, lower loop limits and a time budget on open and calculate, one datasets rewrite per event, print/save/links/focus from clicks only, a runaway script abandoned and the form's scripts turned off, which the app says in a toast and on the notice bar, with a button to the JavaScript console, and doc_info reports as xfa_scripts_off) and what open-time scripts changed is noted. A script that fails partway keeps what it changed before the error, as JavaScript does (forms often trip over an object an earlier version had after their first lines did the work). Missing: a page area's relevant=\"-print\" (on a synthetic form Acrobat still prints the page but leaves it blank; PdfCraft prints its content, #2574); a page break before the first section (Acrobat opens an empty body page first when the first section has breakBefore targetType=pageArea, with or without startNew, as seen on synthetic forms; PdfCraft skips a break on an empty page and lays out one page fewer, #2574); loops inside nested calls are only stopped by abandoning their thread, and script memory is not capped; the change event per keystroke; xfa.template, connections and data descriptions; a hidden instance of a repeating subform hides them all; barcodes are drawn as their text, not bars; keep rules; metrics are approximate and Acrobat fidelity is eyeballed on real forms, not measured (#60)"

+notes = "Active XFA layout skips PDF-container document-script initialization for the Acrobat console/field context, so fallback-viewer scripts do not run there. Scripts remain in the file/listing; explicit console/field and XFA alerts still run. Ordinary PDF, static XFA and unlaid-out shells keep document scripts; static-conversion undo restores the XFA policy. Changed growable multiline text (no fixed h) reflows from final datasets after edits, with or without scripts; pages/widgets refresh and undo/redo, save/reopen and print retain all text. Oversized text still uses the existing read-only page-text fallback with a warning; fixed-height fields do not reflow. Repeated page-master buttons resolve their own PDF field to the shared XFA click script; the numPages-based print script requests printing from every copy, including after save/reopen (#2572). Rich-text exData/maxLength is carried into AcroForm MaxLen, reported by form_fields and enforced by form_fill (Unicode characters); limits and accepted values survive save/reopen (#2570). laid out from the template on open by the xfa crate (positioned, tb, lr-tb, table/row, page masters (a page area with no occur repeats without limit, one with occur max=1 is used once, one with occur min=1 the body never reached gets a page after the body, as Acrobat Pro does on a synthetic form), breaks, repeated header rows, borders and fills of flowed subforms (a page break between their children gives each page's part a closed border, the margins repeated at the cut, as measured on a synthetic form in another viewer, and a child's own page break breaks them the same way; one holding an item that doesn't fit on its page, cut across pages or placed past the content area's bottom, is drawn without its border, with a layout warning), captions, rounded and inverted border corners, rich text (its http, https and mailto links clickable), JPEG/PNG/GIF/BMP/TIFF images) into real pages and AcroForm fields (text, password, date with AFDate formats, check boxes and radio groups (each box placed by its field's margins, caption and paragraph alignment as measured on two synthetic forms in another viewer: with no caption at the right of the content area, beside a reserved caption where the alignment puts it, and a caption without a reserve taking the rest of the field; a check box's own margin larger than the box draws a bigger box there, which isn't copied), drop-downs and list boxes with shown/saved item pairs and multi-select, signature fields (each named by its SOM path, under a generated field for each step above it, so that another viewer, which lays the form out again, finds a signature made here, as seen on a synthetic form, and a box signed here keeps its signature, and that name, when a script lays the form out again; a box whose path, or a part of it, the file already gives another field keeps its own name, and its signature isn't found there yet), image fields showing their picture (pictures decoded once per document, at most 20 million pixels, and reused across re-layouts), buttons with reset/print/save/URL), filled from the datasets packet (including rows another viewer added), saved as an incremental revision with the values merged into the datasets so Adobe's viewers show them; usage rights the form carried (/Perms /UR3) are taken off with a note, as the layout voids them and a form with void usage rights opens with every field locked; doc_info reports xfa_layout. CLI info reports the laid-out page/field counts and dimensions while retaining the input file size and raw counts as pdf_pages/acroform_fields; text and render use those pages too, preserving copy permissions and leaving the source file unchanged (#1645). XFA JavaScript and FormCalc (form.xfa-formcalc) run in the js crate's XFA object model (xfa.form, SOM resolution, rawValue, formattedValue in a date display picture's pattern (number and text display pictures still give the raw value), presence, access, instance managers, xfa.host, xfa.layout, xfa.event): initialize and calculate on open, exit, validate and calculate after a field changes, click for buttons (through js_run and the app), with rows added and removed, subforms shown and hidden, and the form laid out again, all as one undo step and kept in the file. All the scripts of one event run on one thread, each in a fresh context on the form as the engine holds it then (nothing shared between scripts; the live form kept up to date in place for values, rebuilt only when the structure changed), so hundreds of calculations run within the open budget. Hostile scripts are bounded per event (merged and capped effects, messages and console lines, lower loop limits and a time budget on open and calculate, one datasets rewrite per event, print/save/links/focus from clicks only, a runaway script abandoned and the form's scripts turned off, which the app says in a toast and on the notice bar, with a button to the JavaScript console, and doc_info reports as xfa_scripts_off) and what open-time scripts changed is noted. A script that fails partway keeps what it changed before the error, as JavaScript does (forms often trip over an object an earlier version had after their first lines did the work). Missing: a page area's relevant=\"-print\" (on a synthetic form Acrobat still prints the page but leaves it blank; PdfCraft prints its content, #2574); a page break before the first section (Acrobat opens an empty body page first when the first section has breakBefore targetType=pageArea, with or without startNew, as seen on synthetic forms; PdfCraft skips a break on an empty page and lays out one page fewer, #2574); loops inside nested calls are only stopped by abandoning their thread, and script memory is not capped; the change event per keystroke; xfa.template, connections and data descriptions; a hidden instance of a repeating subform hides them all; barcodes are drawn as their text, not bars; keep rules; text is measured at the exact standard-14 widths of the face it is drawn in (bold, italic and Times included), not in the template's own typefaces, and Acrobat fidelity is eyeballed on real forms, not measured (#60)"

Annotations keep the colours they were given (both /AP appearances and the no-/AP Highlight fallback), so a Multiply highlight over a dark background shows the marked-up words in the highlight's colour instead of a flat bar that hides them (#1548). Presets: black on white, white on black, yellow on black, green on black, or a custom #RRGGBB pair; only_black limits the mapping to near-black paints (a 10% luminance threshold — our choice; Acrobat's was not observed). Display only: the document is not changed and print and export are unaffected; print previews and view snapshots render with the document's true colours (a preview matches the uncoloured printout, and a snapshot is an export surface), so reading colours apply to the reading view only.

French locales (fr, fr_FR, fr_CA, fr_BE) select the French catalog, German locales (de, de_DE, de_AT, de_CH) the German one, Hungarian locales (hu, hu_HU) the Hungarian one, and Norwegian locales (nb, nb_NO, and no/nn until a Nynorsk catalog exists) the Bokmål one. German search hints reserve shortcut space, Home cards bound translated text, certificate Subject has its own context, and inserted tool names keep their capitalization. The sentences the layers below word for themselves (accessibility findings and the saved report, PDF/A problems, signature details, page-range mistakes, edit labels) are handed over apart from the document's own values and go through the catalog too, through said(&i18n::words); Spanish, Italian and Brazilian Portuguese translate them, Polish the signature details and the changes after signing; strings absent from other catalogs fall back to English. OS error details, and faults rather than mistakes, stay as they are. Auto detects the Windows display language after explicitly named supported locale overrides; neutral C/POSIX launcher locales are skipped on Windows, with Chinese script/region mapping and English fallback. Arabic (ar and every ar-* locale) covers commands, dialogs and panels with the six CLDR plural forms. Catalogs stay logical and egui 0.37's epaint applies UAX #9 reordering; Arabic and Kurdish labels take an explicit right-to-left paragraph direction and stock chrome is mirrored through Style::right_to_left. Missing: native and browser end-to-end RTL input, IME and complex bidirectional workflows are not yet qualified; Czech dialogs, Chinese and Telugu font delivery (native release builds embed LXGW WenKai Lite for Simplified Chinese, while the web build has no Chinese face beyond BIZ UDPGothic and the release-pinned craft-fonts has no Telugu face), the engine's sentences in the other catalogs, a full localization audit."

+
+The checked-in, resolved Cargo graph pins `winit` to storytold/winit
+`a517b3846ee8457d84ee4975110bfda6797c44dc` and the egui crates to storytold/egui
+`6d518fc799681571963842f95b55a6b68431b15a`. Neither `vendor/winit` nor
+`vendor/egui-wgpu` is a root `[patch.crates-io]` path entry. The retained copies
+record the app's earlier patches; their source-reading tests establish provenance,
+while the resolved forks and their behavioral tests establish runtime behavior.
+
+The retained winit copy has upstream base `e9809ef54b18499bb4f2cac945719ecc2a61061b`,
+as recorded in `vendor/winit/.cargo_vcs_info.json`. Its thirteen patch rows below

-| hayro-interpret | 0.7.0 | Apache-2.0 OR MIT | (1) select `/AP /N` appearance states via `/AS` (checkboxes, radios, stateful icons) and honour the NoView flag; (2) Type3 Unicode fallback to `/Encoding` glyph names, then printable ASCII; (3) `Type3Glyph::advance_width`; (4) `InterpreterSettings::ocg_overrides` for viewer layer toggles; (5) soft masks whose group lacks `/CS` were dropped (Chrome gradient text); (6) paint nesting cap `MAX_PAINT_NESTING` for tiling patterns and Type 3 glyphs (self-referencing content overflowed the stack); (7) CID width ranges in `/W` and `/W2` clamped to `MAX_CID` (a `0 4294967295 w` range hung); (8) `InterpreterSettings::hide_comments` skips markup annotations but keeps widgets and links (View ▸ Hide all comments); (9) `image_size_ok`: images and masks over 2^28 pixels are not decoded (a fuzzed `/W 4294967295` stencil mask allocated 4 GiB); (10) `MAX_NESTED_PAINTS`: nested paints (forms, Type 3 glyphs and tiling patterns inside one another) share a per-page budget of 50,000 (a glyph showing eight glyphs of its own font, sixteen deep, hung); (11) depends on skrifa 0.47 instead of 0.42 (upstream read-fonts fixed a Type 1 tokenizer that recursed through runs of numbers: a fuzzed font hung or overflowed the stack), with the one API change (`Charset::glyph_id` returns `Option`); (12) annotation appearances whose `/BBox` or `/Matrix` collapses to a line or a point are skipped (mapping them onto `/Rect` divided by zero and handed the device infinite or NaN matrices); (13) a Highlight annotation without a usable normal appearance is drawn from its `/QuadPoints`, `/C` and `/CA` with Multiply blending, as pdfcraft-annot draws highlights (it was not drawn at all); (14) simple-font `/Widths` (`read_widths`): entries only for codes 0–255 (one entry per code below `/FirstChar` was allocated: `4294967295` asked for 34 GB), an entry that isn't a number leaves its code missing instead of ending the array, and a `/LastChar` below `/FirstChar` gives no widths instead of discarding the font for a standard one; (15) the appearance box is mapped onto `/Rect` corner to corner: the translation now accounts for the scale (an appearance whose box didn't start at the origin and differed in size from `/Rect` was drawn shifted); (16) a clip set by `W`/`W*` takes effect after whichever path-painting operator ends the path (`S`, `f`, `B`, … as well as `n`; ISO 32000-2 §8.5.4): it was applied only on `n`, so `re W* S` clipped nothing and the clip stayed pending for a later, unrelated `n`; (17) `InterpreterSettings::cancelled`: once set, interpretation stops before the next content operator (a render pool sets it for every worker when dropped, after an edit or on closing, and for one worker when the watchdog gives up on its render, so renders whose answers nobody can receive stop instead of running to the end); (18) `MAX_PAGE_CONTENT`: the content a page holds at once (its contents, and the forms, tiling patterns and Type 3 glyph procedures being painted) stays within 512 MiB (`decode_content`; once it runs out, `InterpreterWarning::ContentTruncated` is reported (once per page by pdfcraft-render) so a truncated page is not a clean render; each level gives its bytes back when it finishes): forms nest fifty deep and each level kept its content while the next ran, so a form painting itself around a stream inflating to 256 MiB would have held over 12 GB; and Type 0 sampled functions take at most `MAX_SAMPLE_ENTRIES` (2^21) table points and `MAX_SAMPLE_VALUES` (2^23) samples, read no further than `/Size` asks (256 MiB of 1-bit samples asked for over 8 GB); (19) mesh shadings (types 4–7) are sampled only inside the area being drawn (`ShadingPattern::encode_within`, which the vendored hayro renderer calls with that area plus a pixel), within 8 visits per pixel of it plus 4 per triangle (`TriangleSampler`), and patches are triangulated one at a time: points far off the page were sampled over their whole bounding box, up to 65536 × 65536 entries (a fuzzed 147-byte patch stream; a synthetic page passed 6 GB in six seconds), ten thousand overlapping triangles ran for minutes, and every patch became 722 triangles before any limit; meshes hold at most `MAX_MESH_PATCHES` (2^16) patches and `MAX_MESH_TRIANGLES` (2^20) triangles, a lattice needs two to 2^19 vertices per row (`/VerticesPerRow 0` pushed empty rows for ever; one huge row read the whole stream), and a page samples at most `MAX_PAGE_MESH_TRIANGLES` (2^25) mesh triangles in all (a mesh painted a thousand times was triangulated a thousand times); each cut logs a warning; (20) PDF function construction is limited to 64 levels and 10,000 total nodes with cycle detection; calculator parsing and evaluation share procedure depth/work budgets, integer division/bitshift/rotation/index are panic-free, and fixed-size stack errors propagate; (21) a Type 0 font drawn with a substitute that isn't CID-keyed (it isn't embedded, or its program doesn't load) draws `.notdef` for a CID of an Adobe character collection (Japan1, GB1, CNS1, Korea1) that it can't find by Unicode: hayro took the CID for a glyph index of the substitute, which numbers its glyphs its own way, so the character was drawn as an unrelated one (𠮷 as "Ｑ" in BIZ UDPGothic); (22) a Type 0 font drawn with a substitute finds a character given with a variation selector (`/ToUnicode`, or Adobe-Japan1-UCS2, which maps the JIS X 0208 forms of the kanji JIS X 0213:2004 redrew that way: CID 1247 is 噂 U+E0100) through the substitute's variation sequences, else as the character alone: such a CID found no glyph and was drawn as an unrelated one; (23) backport of hayro 0.8's `gradient` module: `EncodedShadingPattern::as_svg_gradient` turns an axial or radial shading into stops of an sRGB gradient (within 0.01 per channel, a stop at every stitching-function bound via `Function::stitching_bounds`) when a native gradient draws it exactly (extended past the box drawn in; a radial one with no background colour); (24) `DecodedImageCache`: decoded image pixels shared across renders through the interpreter cache within a 64 MiB budget (an image-heavy page decoded its thousands of images again per tile and per scale), keyed by every decode input (`DecodedImageKey`: the stream's place and dictionary bytes, its object, mask/stencil/raster output, interpolation, decode target size, preview or final); images under a transfer function and inline images are not cached, an image over the budget is never kept, and a poisoned lock decodes uncached; (25) `Device::actual_text` hands the device a marked content sequence's `/ActualText` (inline or named in `/Properties`), so text extraction keeps the Thai, Indic and Arabic clusters Chrome marks this way (their shaped tone marks and vowels have no Unicode of their own); (26) non-embedded simple fonts drawn with a standard-font stand-in build the Latin Extended-A letters the stand-in lacks (`/Gbreve`, `/Idotaccent`, `/Scedilla`, `/aogonek`, `/ccaron`…) from the base letter and accent it has (`StandardKind::composite_glyph`, `ACCENTED_LETTERS`): PDFium's Foxit stand-ins hold only the Standard/WinAnsi/Mac Roman glyphs, so iText letters with Times New Roman unembedded showed blanks for Ğ, İ, Ş, ğ and ş; the comma-below letters (`/scommaaccent`, `/Tcommaaccent`, `/kcommaaccent`…, found by character, so `/uni0136` and the glyph list's `/Kcedilla` too) are the letter and the font's comma, smaller and under the baseline, since the stand-ins have no `commaaccent` (Romanian ș drew nothing and ț a cedilla in forms laid out from XFA; ģ, whose comma is turned and above, is not built); (27) an embedded TrueType font without a base encoding reads its codes as WinAnsi for text extraction (`EmbeddedKind::code_to_unicode_name`), matching pdftotext's output, instead of Standard: OCR text layers of scans write WinAnsi codes with no `/Encoding`, and Standard has no ü, ö or ß and reads é as Ø (glyph selection unchanged); (28) an image whose pixels hold at most 16 bits of samples (an 8-bit Separation or DeviceN image, a 1-, 2- or 4-bit gray or indexed one) is converted once per possible pixel value through a lookup table instead of once per pixel (`rgb_via_lookup`): a spot-colour tint transform is often a PostScript calculator program, run for every pixel, so a fillable character sheet's 3304 × 4105 DeviceN background took four seconds and 430 MB to draw a page; each entry is converted on its own (`convert_each`), so a tint transform giving the wrong number of components for a value the image never uses cannot shift the colours of the values it does; (29) `Device::begin_annotations`/`end_annotations` bracket the page's annotations, so a device can tell comment paints from document paints (reading colours recolour the document, never a comment, #1548); (30) the Annex D.2 alias codes read as the ink they draw: WinAnsiEncoding 0xA0 and 0xAD, and MacRomanEncoding 0xCA, carry the glyph names `space` and `hyphen` -- the names those tables also give 0x20 and 0x2D -- not `nbspace` and `sfthyphen`, whose glyph list values U+00A0 and U+00AD are invisible formatting characters. Extraction hid drawn ink behind them, so search and redaction matched neither (`XiaoBiaoSong.pdf` in the pdf.js corpus drew 104 soft hyphens; across the 989 files the soft hyphens we extract fall from 117 to 13 and the non-breaking spaces from 30 to 26, what remains coming from `/ToUnicode` maps, which say so explicitly). The base table only, in the text direction only: a `/Differences` name keeps its glyph list value and glyph lookup is untouched, both as pdftotext does; (31) a Type 0 sampled function keeps its samples in one flat array indexed by strides (`Type0::entry`) instead of a hash map keyed by each grid point: the map was built again, one hashed insert per sample, every time a shading using the function was painted (a 2,097,152-sample ramp painted 30 times took 38 s; `bug1721218` in the pdf.js corpus spent most of a 1.5 s page on it); the interpolation is unchanged, so results are bit for bit the same, a sample missing from a short stream still gives no value, and the maximum sample value is computed without overflowing at 32 bits per sample; (32) the decoded-image cache (24) keys a decode by the size the image is drawn at only when a JPX stream decodes it or its soft mask or mask (`decode_reads_target`): JPX is the only filter that decodes a reduced resolution for a size, so a JPEG or Flate scan was decoded again at every zoom step and kept once per zoom level; one decode now serves every size; `InterpreterCache::decoded_image_decodes` counts the cache's decodes; (33) Coons and tensor-product patches copy their vertices' colours less: each point of a patch's 20 × 20 triangle grid is interpolated once (`generate_patch_triangles`; each cell interpolated its four corners itself, 1,444 interpolations a patch for 400 points), a cell's second triangle takes the vertices its first copied, and the mesh sampler moves a patch's triangles into device space instead of copying each vertex (`TriangleSampler::sample_owned`); the same values, 10–16% faster on mesh-gradient pages; (34) `color::tint_transform_runs`: how many colours the calling thread has run through a Separation or DeviceN tint transform (counted once per batch in `convert_f32`), so a test counts patch (28)'s once-per-sample-value runs instead of timing them (its 10 s deadline failed on a busy FreeBSD VM in CI); (35) `EncodedShadingPattern::extent`: where a mesh shading (types 4–7) can paint at all, the pixels its triangles touched when it was encoded (`None` for the types that paint everywhere, and when the shading has a `/Background`), so the renderer samples a texture there alone and skips a mesh with nothing on the canvas; (36) a mesh shading's pixel whose corner no triangle holds strictly (on an edge two triangles share, or on the mesh's side) takes the triangle that covers its centre, edges included (`Triangle::covers`): testing only the corner left a white seam along every shared edge, and the colour is still taken at the corner; (38) the `/DefaultGray`, `/DefaultRGB` and `/DefaultCMYK` colour spaces of a resource dictionary (ISO 32000-2 §8.6.5.6) replace the device space content selects: with `g`/`G`, `rg`/`RG`, `k`/`K` and `cs`/`CS` (by name, or through a `/ColorSpace` resource that is a device space), and as the `/ColorSpace` of an image XObject, an inline image or a shading painted by `sh` or as a shading pattern (`DefaultColorSpaces`, looked up once per content window in the resources and those they inherit, so a form XObject without a default of its own draws in its page's, as Poppler and MuPDF draw it); a default that is a Lab, Indexed, Pattern or device space, has another number of components or is no colour space is ignored and device colour is drawn as before; device spaces inside other spaces (an Indexed base, a Separation or DeviceN alternate, a Pattern's underlying space), shading dictionaries, masks and transparency group spaces are unchanged, and the decoded-image cache (24) keys a decode by the default it was drawn in. hayro drew device colour as it was, so pages that calibrate it this way (common in PDF/A) came out in the wrong colours; (39) knockout groups (#2971): `Device::set_knockout` right after a `/K true` group is pushed; `Device::knockout_image` for an unmasked image before its group is pushed, when `Device::in_knockout_group`: the device clears its placement rectangle only if it will draw the image (on the canvas, not a preview's tiny image, and it decodes), decoded at its draw size so the draw reuses that decode; and, when `Device::knockout_erase_wanted`, a nested group's content drawn once between `begin_knockout_erase` and `end_knockout_erase` before the group itself, which then always gets a layer of its own; (40) an optional content membership dictionary's visibility expression (`/VE`: `/And`, `/Or`, `/Not`, nested up to 32 deep) decides its visibility ahead of `/OCGs` and `/P` (ISO 32000-2 §8.11.2.2); it was ignored, so content under it stayed visible with its layers hidden; a malformed expression, including one naming an object the document doesn't list in `/OCProperties /OCGs`, falls back to `/OCGs` and `/P` (#2986); (41) a transparency group that is neither isolated nor knockout, entered at full opacity with no soft mask and Normal blending, is drawn straight onto the page instead of into a layer of its own (§11.4.7: its elements composite with the backdrop; the layer made a `/BM /Multiply` highlight appearance an opaque block, #1968); (42) text in a Type 3 font is drawn filled whatever the text rendering mode, except mode 3 (invisible): only that mode has any effect on Type 3 fonts (ISO 32000-1 §9.3.6). Stroking ran the glyph procedure a second time, so `2 Tr` made bitmap fonts look bold, `1 Tr` painted an uncoloured glyph in the stroking colour, and `7 Tr` hid it; (43) Lab colour spaces honour their own `/WhitePoint`: L\*a\*b\* goes to XYZ relative to that white, is Bradford-adapted to D65 and converted to sRGB (ISO 32000-2 §8.6.5.4) instead of through `LAB.icc` as if every white were D50 (a D65 blue came out 45 levels too red; the profile is removed); components normalised to [0, 1] (`manual_scale`, an `/Indexed` palette over Lab) map onto L\* 0..100 and the a\*/b\* `/Range`; (44) a Type 0 font whose `/ToUnicode` is the name `/Identity-H` or `/Identity-V` (not a CMap stream; WSCAD writes it) reads each code as its Unicode value, as Acrobat shows it (`Type0Font::identity_to_unicode`); the identity CMap the name resolved to maps codes to CIDs only, so such pages had no text to select or find; (46) an image XObject's group applies the fill opacity, so the fill alpha is reset to 1 before a stencil mask takes the fill colour as its paint, and a pattern paint drops the opacity it captured at `scn` (`Pattern::without_opacity`) (it was applied twice: a mask at `ca 0.5` was drawn at a quarter, #2975); (47) `path_as_rect`: a five-element path is a rectangle only when its four points are distinct, each step from one to the next runs along a single axis, and the last returns to the first. The length test admits one MoveTo and four LineTo as well as one MoveTo, three LineTo and a ClosePath, and asking only that every corner of the bounding box was visited says nothing about the order or the steps between, so a five-point polyline whose ends reached the corners was painted as that box -- a fourth side the path does not have -- and a clip of that shape was discarded; the coordinates are compared exactly, since the matrix is applied after this check and a `cm` of 10,000 turns `is_nearly_equal`'s 256th of a unit into tens of device units (#3327); (48) an `/ICCBased` colour space is cached by what its profile is read from (`IccProfileKey`): the stream object it names, looked up without reading the stream, and then the stream's dictionary and its own bytes (decrypted, not decoded), so a byte-for-byte copy of a profile in another object is read once, and a profile stream written directly in its array, which reports the object holding the array as every other stream written there does, is told apart by its bytes. hayro keyed it by the stream dictionary's bytes alone, so two different profiles with the same `/N` and `/Length` shared whichever was read first, and colours in the second were drawn through the first. `InterpreterCache::icc_profile_reads` counts the profiles read; (49) `OpenTypeFontBlob::new` also accepts a `post` table version 1.0, 2.0 or 3.0 written with its 16-bit halves swapped (`00 00 00 03`), as ScanSoft PDF Create! embeds every font; such fonts were refused and their text drawn with a substitute (Hebrew came out garbled or missing, #2946); `glyph_names` reads such a table from a copy with the version written correctly, so a 2.0 table's names serve `/Differences`. Any other unknown version is still refused (pdf.js 9462); (50) `CffFontBlob::glyph_index_by_name` looks a glyph name up in a name to glyph map built on first use (shared between clones) instead of searching the whole charset, with a string lookup per glyph, for every character code of a font; the first glyph with a name still wins | (1) `raster::tests::widget_appearance_states`; (2, 3) `xtask text-oracle` on corpus/pdfjs issue918; (4) `raster::tests::layer_override_hides_content`; (5) `raster::tests::soft_mask_without_group_colour_space_is_applied`;

-| hayro | 0.7.1 | Apache-2.0 OR MIT | (1) `RenderSettings::{x_offset, y_offset}` to render one tile of a large page; (2) images over `MAX_IMAGE_PIXELS` (2^28) are skipped (a fuzzed `/W 4294967295` hung in resampling); (3) `tiling_cell_scale` keeps a tiling pattern's cell pixmap within 3000 px a side whatever its `/XStep`/`/YStep` (a fuzzed step far beyond `/BBox` allocated 2 GB); (4) stroke widths clamped to 4 × (canvas width + height) device pixels (a fuzzed `/LW 9223372036854775807` allocated 10 GB in stroke expansion); (5) `usable_dash_pattern`: a stroke whose dash pattern could cut it into more than `MAX_DASHES_PER_STROKE` (250,000) pieces, counting kurbo's restart of the pattern at every subpath and `ClosePath`, is drawn solid (a fuzzed `/D [[11] 0]` on a line from x = 92234775807 allocated over 5 GB, `[0.000001] 0 d` on a 20 pt line over 10 GB); (6) a dash pattern with a negative or non-finite entry, or a period that isn't positive, is drawn solid (`[-1 -1] 0 d` looped for ever in kurbo); (7) `render_size` and `render_into`: render into a buffer the caller allocates (PdfCraft renders into pixel-aligned memory that the GUI takes over as texture data); `render` is `render_into` on a new pixmap; (8) checked image source/target/RGBA, alpha-premultiplication scratch and intermediate sizes before resampling, finite transforms and exact source/mask buffers; sources wider than u16 may shrink before backend limits, with a 2^20 source-axis cap and conservative 128 MiB filter-planning estimate; an over-limit or failed resize keeps the original image resolution and geometry when the source fits the backend, otherwise skips it, with a logged warning; staging, resampling output/scratch, RGBA conversion and padding buffers use fallible reserves; (9) `may_paint_canvas`: a fill or stroke whose control-point box, grown by how far its paint reaches past the path (half the stroke width times the larger of the miter limit and √2) plus 0.5 user units and 2 pixels, misses the canvas is not drawn, so a tile no longer strokes and fills every path of its page (item 5 of #623); `set_skip_offscreen_paths` turns this off for the regression test; (10) backport of hayro 0.8: shadings that `as_svg_gradient` can represent are painted as a `vello_cpu` linear or two-point radial gradient instead of a texture sampled pixel by pixel through the shading function (InDesign fades are luminosity soft masks of one full-page axial `sh`: 40 on a report page took 15 s at 144 dpi, now under 1 s); without upstream's half-pixel shift, which suits vello_cpu 0.3 but moves 0.0.8's gradients off pixel centres; (11) `may_paint_rect`: an image whose stream-size box, mapped to the device, misses the canvas is skipped before decoding (decoded data can only shrink against that box), so a tile of an image-heavy page no longer decodes, resamples and rasterizes every image on it; (12) preview renders (`InterpreterSettings::preview`: backdrops, thumbnails, grid cells, signature-drag backgrounds) skip images under `PREVIEW_MIN_IMAGE_AREA` device pixels, while final renders always draw them; (13) reading colours (#897): `RenderSettings::color_replacement` takes a `ColorReplacement` (text colour, background, `only_black`, `line_art`) that remaps solid text and line-art paint while rendering, glyph outlines counting as text and stencil-mask ink as line art; images, image alpha masks, soft masks and pattern cells keep their colours; `render_pdf` gains a `color_replacement: Option<ColorReplacement>` argument (pass `None` for true colours); the upstream-only `[dev-dependencies.log]` entry is removed from `Cargo.toml` (log is a normal dependency since the logging patch), so `cargo test -p hayro` runs this crate's unit tests; (14) a shrunk, interpolated, axis-aligned image is snapped to whole device pixels: shrunk once to its rounded device rectangle and drawn 1:1 at the rounded corner, instead of a ceil-sized raster resampled again at a fractional scale and offset (`snap_minified_image`; scans looked soft next to Acrobat); (15) a soft mask of another size than its image is filtered when shrunk, whatever its `/Interpolate` (#1649): such a mask carries the shape on its own (Word saves text as a tiny black image with a glyph-bitmap mask), and nearest-neighbour dropped every stroke thinner than the shrink factor; (16) under a soft mask or a blend mode, axial and radial shadings are sampled instead of drawn as native gradients (#2128): vello_cpu 0.0.8 copies an opaque gradient over fully covered tiles without the mask or blend mode, so PowerPoint's faded gradient fills came out solid; (17) the renderer keeps annotation paints out of the reading-colours mapping between `begin_annotations` and `end_annotations` (#1548); (18) the page renders as one transparency group; under reading colours its background is painted inside it as the initial backdrop, so a Multiply highlight blends with the dark background instead of staying an opaque block, and otherwise the background stays outside, so a blend mode over an empty part of the page keeps its colour instead of blending with the white paper (#2970); (19) `set_paint` samples a mesh shading's texture over its triangles alone (`EncodedShadingPattern::extent`, padded rather than repeated) and skips a mesh with none on the canvas: a BricsCAD plan's 310 one-triangle `sh` each covered the whole tile, 2 s per 1024 px tile at any zoom (the watchdog gave the page up on a busy machine), now about 70 ms; (20) a tiling pattern whose step is too large for a cell pixmap, where what is painted (a fill, or a stroke with its width) can only show the first cell (PowerPoint's `/XStep 2147480100` for a picture fill drawn once), has its `/BBox` drawn at full scale with a transparent border and padded instead of tiled (`shows_one_cell`; a cell whose scale isn't finite and positive, from a `/BBox` too thin to divide by, keeps the old path: `usable_cell_scale`); shrinking the cell to fit the 3000 px limit of (3) left the picture under a pixel, so network diagrams lost their pictures (#3349); (22) knockout groups: while one is innermost, fills, strokes, glyph outlines and shadings are drawn with `Compose::Copy` (weighted by coverage), so each element replaces what earlier elements of the group drew instead of compositing over it; an image or nested group, drawn into a layer of its own, first has what is under its shape cleared (`knockout_image` for an unmasked image's rectangle, only when `draw_image` will draw it, decoded at the size it is drawn; a knockout erase pass that draws a nested group's content with every paint clearing instead of painting, a shading fill's clear clipped to the shading's `/BBox` as its paint is) and then composites over it (#2971) | (1) `raster::tests::tiles_match_full_render`;

-| hayro-syntax | 0.7.2 | Apache-2.0 OR MIT | (1) Page-tree cycle guard in `resolve_pages` (visited set + depth cap): a `/Kids` loop among compressed objects overflowed the stack and aborted the process; (2) `ccitt_size_ok`: CCITT images wider than 2^20 columns or over 2^28 pixels are not decoded (a fuzzed `/Columns 4294967295` allocated 4 GiB); (3) Flate/LZW predictor row widths are saturating `usize`, a zero width is refused and a row longer than the data is not allocated (a fuzzed `/Columns 9223372036854775807` wrapped to a 2^61-byte allocation and aborted); (4) the inline-image end-of-data check (`EI`) doesn't nest inside its own look-ahead and examines at most 256 candidates and steps (50 images with "EI" in their data ran for over ten minutes); an EI followed by a delimiter (EI%..., EI[...) ends the image like one followed by white space; only a regular character after EI skips the candidate; (5) a stream whose `/Length` is wrong is recovered only when `stream` is the next token — scanning ahead to a later object's `stream` made an indirect appearance-state dictionary (Quartz checkboxes: `/AP /N` → `<< /Yes … /Off … >>`) render as a non-form, so the widget was skipped; (6) JPX rescaling uses an exact integer sample range for 1–32-bit components (32 shifted past u32, and floating-point maxima at 25–31 bits wrapped to zero), and refuses zero-sized rows; (7) `decode_limit`: Flate (through flate2 and the fallback inflater), LZW and RunLength never write past `MAX_DECODED_STREAM` (256 MiB), or, for the last filter of an image of known size, past twice its pixel bytes (a predictor tag byte per byte), at most 1 GiB; `Stream::decoded_within` for budgeted callers; a page's `/Contents` array shares one `MAX_DECODED_STREAM` (a 2 MB page whose content stream or 8 × 8 image inflated to 2 GB took the renderer past 3 GB in under a second; naming the stream twenty times in `/Contents`, 5 GB); (8) high-precision numbers (jsPDF MediaBox coordinates with over 19 digits) parse without overflowing the u64 mantissa: fractional digits past it are dropped, integer digits past it scale the value (a real, kept finite); (9) large dictionary indexes are built on first use and shared across repeated reads within each PDF (#307); the validated-byte cache is bounded, reader contexts remain separate, repairs and inline/content dictionaries bypass sharing, and small dictionaries stay eager; (10) decoded object-stream slots publish once under contention, cold loading rejects recursive dependencies, and xref repair serializes without holding recursive read guards; this permits one parser per native render pool with private worker caches; (11) `sync.rs`: a poisoned lock is recovered instead of unwrapped (a worker panic no longer cascades into every reader of the same PDF), and xref repair takes a blocking write lock instead of asserting a non-blocking one; (12) `SegmentList` (`util.rs`) returns `None` for an out-of-range index instead of panicking; (13) a page's `/UserUnit` scales `render_dimensions` and `initial_transform`, so the page and everything on it are sized in points, as Acrobat shows them; it is read as Acrobat reads it (the page's own entry, not inherited; a number from 1 up, at most 75,000; anything else counts as 1), and a page without it keeps exactly the transform it had; (14) revision 2–4 passwords are tried as given and then in PDFDocEncoding (`legacy_passwords` in `crypto/mod.rs`, which resolves the upstream `TODO: Convert to PDFDocEncoding`): passwords arrive as UTF-8 text, so a password with characters outside ASCII (`Çok güzel`, `ılık€`) written in PDFDocEncoding, as ISO 32000-2 §7.6.4.3.2 asks and qpdf and Acrobat write it, was always wrong; (15) page content is read a piece at a time (`page::ContentReader`, `Page::content_reader`): plain streams and Flate streams without a predictor are decoded as they are read, with a budget of 64 times their compressed size and never less than `MAX_DECODED_STREAM` (a stream that expands past it is cut and reported); other streams are decoded whole, as before, and share `MAX_DECODED_STREAM`. The content tokenizer reads a window at a time (`UntypedIter::new_window`, `TypedIter::needs_more`, `TypedIter::committed`): an instruction that runs past the window is not decided until more data follows, which `Reader` records by flagging reads and `at_end` past the end of the data, including through the clones the parser makes. The Flate decoder keeps its own 32 KiB history, so it pauses at any output size. `ContentReader::new` reuses raw/decrypted stream bytes for budget accounting and piece creation, and `decoded_raw_within` applies the existing Whole-stream filters and limits to those bytes without decrypting twice; (16) revision 5–6 (AES-256) passwords are tried in their SASLprep form (RFC 4013, then UTF-8, at most 127 bytes, as ISO 32000-2 §7.6.4.3.3 Algorithm 2.A asks and pdfcraft-crypt writes them) and then, if that differs, as given (`aes256_passwords` in `crypto/mod.rs`, which resolves the upstream `TODO: Do the above.`; `stringprep`, already in the tree through pdfcraft-crypt, is an optional dependency enabled by `std`, and without `std` passwords are used as given): the renderer used the password as typed, so one that SASLprep changes (a decomposed `café`, a no-break space, the fullwidth `ａｂ` a Japanese IME types in full-width mode) was wrong, although pdfcraft-cos accepted it: protecting a document with such an open password was rolled back ("the password is incorrect"), and a file with such a password did not open with it.; (17) CCITT `/Rows 0` means the height is not predetermined (ISO 32000-2 Table 11), not zero rows: scanned Group 4 pages written that way rendered blank; (18) The streaming Flate decoder (`lzw_flate::flate::fallback`) copies a back-reference in runs of up to its distance (`extend_from_within`), not byte by byte. The copy reads only bytes already in the output, and a copy whose source does not exist still writes nothing, so the bytes are those a byte-by-byte copy writes. Inflating the A1 sample's content stream (278.6 MB) takes about 14% less time (0.66 s to 0.56 s); the output is identical; (19) CCITT `/Rows` below the image's `/Height` decodes to the height: a plotter driver wrote `/Rows` equal to `/Columns`, so only the first rows were decoded and the rest drawn black (#3308) (20) `stream` followed by spaces or tabs and then the line break (`stream \r\n`, as Microsoft Reporting Services writes it) starts the data after the line break; the content stream was taken to start at the space and the page rendered blank.; (21) a JP2 colour specification naming an enumerated colour space the decoder refuses (CIEJab in a veraPDF fixture, YCbCr, PhotoYCC, YPbPr, bilevel…) no longer fails the image: it is decoded again from a copy whose `colr` names the space the decoder assumes without one, greyscale, sRGB or CMYK by component count, as MuPDF and Poppler draw it (`without_refused_enumerated_colour`; the page drew blank, #3306); (22) an object stream's index of `objnum offset` pairs is parsed once per stream and kept beside its decoded data (`ObjectStreamIndexes`, `XRef::with_object_stream_indexes`), and an offset past `usize` is malformed instead of wrapping: `XRef::get_with` parsed the whole index again for every object it fetched from the stream, so reading all of a stream of N objects took N² steps (a Firefox page whose 65,542 objects share one stream took 37 s to draw and 40 s to extract its text); (23) the inline-image end-of-data look-ahead no longer rejects a candidate `EI` because a byte above 0x7F lies between it and the next one: when the candidate is the end, those bytes are the content stream that follows the image, and its strings carry such bytes (WinAnsi `(Grüße) Tj`, the two-byte codes of any Type 0 font), so the operator check that follows decides alone, bounded as in (4) (a scanned page whose OCR text held an accented word and a later capital "EI" — EINGANG, BEI, KLEIN — drew and extracted nothing after the image: 40 of 275 pages across five real documents); (24) `xref::prev_offset`: a trailer `/Prev` written as a reference `N G R` is read as the offset that object holds when the section's own entries place it (iText's `indirectPrev.pdf`; each section's entries are read before its `Prev` is followed), and otherwise as offset N (tiff2pdf; JHOVE's PDF-HUL-157 files, #2366), as `pdfcraft-cos` and other readers take it, so the earlier sections' pages are seen instead of one | (1) `cos/tests/writer.rs::page_tree_loops_in_object_streams_do_not_crash_readers`;

(3) `Type3Glyph::advance_width`; (4) `InterpreterSettings::ocg_overrides` for viewer layer toggles; (5) soft masks whose group lacks `/CS` were dropped (Chrome gradient text); (6) paint nesting cap `MAX_PAINT_NESTING` for tiling patterns and Type 3 glyphs (self-referencing content overflowed the stack); (7) CID width ranges in `/W` and `/W2` clamped to `MAX_CID` (a `0 4294967295 w` range hung); (8) `InterpreterSettings::hide_comments` skips markup annotations but keeps widgets and links (View ▸ Hide all comments); (9) `image_size_ok`: images and masks over 2^28 pixels are not decoded (a fuzzed `/W 4294967295` stencil mask allocated 4 GiB); (10) `MAX_NESTED_PAINTS`: nested paints (forms, Type 3 glyphs and tiling patterns inside one another) share a per-page budget of 50,000 (a glyph showing eight glyphs of its own font, sixteen deep, hung); (11) depends on skrifa 0.47 instead of 0.42 (upstream read-fonts fixed a Type 1 tokenizer that recursed through runs of numbers: a fuzzed font hung or overflowed the stack), with the one API change (`Charset::glyph_id` returns `Option`); (12) annotation appearances whose `/BBox` or `/Matrix` collapses to a line or a point are skipped (mapping them onto `/Rect` divided by zero and handed the device infinite or NaN matrices); (13) a Highlight annotation without a usable normal appearance is drawn from its `/QuadPoints`, `/C` and `/CA` with Multiply blending, as pdfcraft-annot draws highlights (it was not drawn at all); (14) simple-font `/Widths` (`read_widths`): entries only for codes 0–255 (one entry per code below `/FirstChar` was allocated: `4294967295` asked for 34 GB), an entry that isn't a number leaves its code missing instead of ending the array, and a `/LastChar` below `/FirstChar` gives no widths instead of discarding the font for a standard one; (15) the appearance box is mapped onto `/Rect` corner to corner: the translation now accounts for the scale (an appearance whose box didn't start at the origin and differed in size from `/Rect` was drawn shifted); (16) a clip set by `W`/`W*` takes effect after whichever path-painting operator ends the path (`S`, `f`, `B`, … as well as `n`; ISO 32000-2 §8.5.4): it was applied only on `n`, so `re W* S` clipped nothing and the clip stayed pending for a later, unrelated `n`; (17) `InterpreterSettings::cancelled`: once set, interpretation stops before the next content operator (a render pool sets it for every worker when dropped, after an edit or on closing, and for one worker when the watchdog gives up on its render, so renders whose answers nobody can receive stop instead of running to the end); (18) `MAX_PAGE_CONTENT`: the content a page holds at once (its contents, and the forms, tiling patterns and Type 3 glyph procedures being painted) stays within 512 MiB (`decode_content`; once it runs out, `InterpreterWarning::ContentTruncated` is reported (once per page by pdfcraft-render) so a truncated page is not a clean render; each level gives its bytes back when it finishes): forms nest fifty deep and each level kept its content while the next ran, so a form painting itself around a stream inflating to 256 MiB would have held over 12 GB; and Type 0 sampled functions take at most `MAX_SAMPLE_ENTRIES` (2^21) table points and `MAX_SAMPLE_VALUES` (2^23) samples, read no further than `/Size` asks (256 MiB of 1-bit samples asked for over 8 GB); (19) mesh shadings (types 4–7) are sampled only inside the area being drawn (`ShadingPattern::encode_within`, which the vendored hayro renderer calls with that area plus a pixel), within 8 visits per pixel of it plus 4 per triangle (`TriangleSampler`), and patches are triangulated one at a time: points far off the page were sampled over their whole bounding box, up to 65536 × 65536 entries (a fuzzed 147-byte patch stream; a synthetic page passed 6 GB in six seconds), ten thousand overlapping triangles ran for minutes, and every patch became 722 triangles before any limit; meshes hold at most `MAX_MESH_PATCHES` (2^16) patches and `MAX_MESH_TRIANGLES` (2^20) triangles, a lattice needs two to 2^19 vertices per row (`/VerticesPerRow 0` pushed empty rows for ever; one huge row read the whole stream), and a page samples at most `MAX_PAGE_MESH_TRIANGLES` (2^25) mesh triangles in all (a mesh painted a thousand times was triangulated a thousand times); each cut logs a warning; (20) PDF function construction is limited to 64 levels and 10,000 total nodes with cycle detection; calculator parsing and evaluation share procedure depth/work budgets, integer division/bitshift/rotation/index are panic-free, and fixed-size stack errors propagate; (21) a Type 0 font drawn with a substitute that isn't CID-keyed (it isn't embedded, or its program doesn't load) draws `.notdef` for a CID of an Adobe character collection (Japan1, GB1, CNS1, Korea1) that it can't find by Unicode: hayro took the CID for a glyph index of the substitute, which numbers its glyphs its own way, so the character was drawn as an unrelated one (𠮷 as "Ｑ" in BIZ UDPGothic); (22) a Type 0 font drawn with a substitute finds a character given with a variation selector (`/ToUnicode`, or Adobe-Japan1-UCS2, which maps the JIS X 0208 forms of the kanji JIS X 0213:2004 redrew that way: CID 1247 is 噂 U+E0100) through the substitute's variation sequences, else as the character alone: such a CID found no glyph and was drawn as an unrelated one; (23) backport of hayro 0.8's `gradient` module: `EncodedShadingPattern::as_svg_gradient` turns an axial or radial shading into stops of an sRGB gradient (within 0.01 per channel, a stop at every stitching-function bound via `Function::stitching_bounds`) when a native gradient draws it exactly (extended past the box drawn in; a radial one with no background colour); (24) `DecodedImageCache`: decoded image pixels shared across renders through the interpreter cache within a 64 MiB budget (an image-heavy page decoded its thousands of images again per tile and per scale), keyed by every decode input (`DecodedImageKey`: the stream's place and dictionary bytes, its object, mask/stencil/raster output, interpolation, decode target size, preview or final); images under a transfer function and inline images are not cached, an image over the budget is never kept, and a poisoned lock decodes uncached; (25) `Device::actual_text` hands the device a marked content sequence's `/ActualText` (inline or named in `/Properties`), so text extraction keeps the Thai, Indic and Arabic clusters Chrome marks this way (their shaped tone marks and vowels have no Unicode of their own); (26) non-embedded simple fonts drawn with a standard-font stand-in build the Latin Extended-A letters the stand-in lacks (`/Gbreve`, `/Idotaccent`, `/Scedilla`, `/aogonek`, `/ccaron`…) from the base letter and accent it has (`StandardKind::composite_glyph`, `ACCENTED_LETTERS`): PDFium's Foxit stand-ins hold only the Standard/WinAnsi/Mac Roman glyphs, so iText letters with Times New Roman unembedded showed blanks for Ğ, İ, Ş, ğ and ş; the comma-below letters (`/scommaaccent`, `/Tcommaaccent`, `/kcommaaccent`…, found by character, so `/uni0136` and the glyph list's `/Kcedilla` too) are the letter and the font's comma, smaller and under the baseline, since the stand-ins have no `commaaccent` (Romanian ș drew nothing and ț a cedilla in forms laid out from XFA; ģ, whose comma is turned and above, is not built); (27) an embedded TrueType font without a base encoding reads its codes as WinAnsi for text extraction (`EmbeddedKind::code_to_unicode_name`), matching pdftotext's output, instead of Standard: OCR text layers of scans write WinAnsi codes with no `/Encoding`, and Standard has no ü, ö or ß and reads é as Ø (glyph selection unchanged); (28) an image whose pixels hold at most 16 bits of samples (an 8-bit Separation or DeviceN image, a 1-, 2- or 4-bit gray or indexed one) is converted once per possible pixel value through a lookup table instead of once per pixel (`rgb_via_lookup`): a spot-colour tint transform is often a PostScript calculator program, run for every pixel, so a fillable character sheet's 3304 × 4105 DeviceN background took four seconds and 430 MB to draw a page; each entry is converted on its own (`convert_each`), so a tint transform giving the wrong number of components for a value the image never uses cannot shift the colours of the values it does; (29) `Device::begin_annotations`/`end_annotations` bracket the page's annotations, so a device can tell comment paints from document paints (reading colours recolour the document, never a comment, #1548); (30) the Annex D.2 alias codes read as the ink they draw: WinAnsiEncoding 0xA0 and 0xAD, and MacRomanEncoding 0xCA, carry the glyph names `space` and `hyphen` -- the names those tables also give 0x20 and 0x2D -- not `nbspace` and `sfthyphen`, whose glyph list values U+00A0 and U+00AD are invisible formatting characters. Extraction hid drawn ink behind them, so search and redaction matched neither (`XiaoBiaoSong.pdf` in the pdf.js corpus drew 104 soft hyphens; across the 989 files the soft hyphens we extract fall from 117 to 13 and the non-breaking spaces from 30 to 26, what remains coming from `/ToUnicode` maps, which say so explicitly). The base table only, in the text direction only: a `/Differences` name keeps its glyph list value and glyph lookup is untouched, both as pdftotext does; (31) a Type 0 sampled function keeps its samples in one flat array indexed by strides (`Type0::entry`) instead of a hash map keyed by each grid point: the map was built again, one hashed insert per sample, every time a shading using the function was painted (a 2,097,152-sample ramp painted 30 times took 38 s; `bug1721218` in the pdf.js corpus spent most of a 1.5 s page on it); the interpolation is unchanged, so results are bit for bit the same, a sample missing from a short stream still gives no value, and the maximum sample value is computed without overflowing at 32 bits per sample; (32) the decoded-image cache (24) keys a decode by the size the image is drawn at only when a JPX stream decodes it or its soft mask or mask (`decode_reads_target`): JPX is the only filter that decodes a reduced resolution for a size, so a JPEG or Flate scan was decoded again at every zoom step and kept once per zoom level; one decode now serves every size; `InterpreterCache::decoded_image_decodes` counts the cache's decodes; (33) Coons and tensor-product patches copy their vertices' colours less: each point of a patch's 20 × 20 triangle grid is interpolated once (`generate_patch_triangles`; each cell interpolated its four corners itself, 1,444 interpolations a patch for 400 points), a cell's second triangle takes the vertices its first copied, and the mesh sampler moves a patch's triangles into device space instead of copying each vertex (`TriangleSampler::sample_owned`); the same values, 10–16% faster on mesh-gradient pages; (34) `color::tint_transform_runs`: how many colours the calling thread has run through a Separation or DeviceN tint transform (counted once per batch in `convert_f32`), so a test counts patch (28)'s once-per-sample-value runs instead of timing them (its 10 s deadline failed on a busy FreeBSD VM in CI); (35) `EncodedShadingPattern::extent`: where a mesh shading (types 4–7) can paint at all, the pixels its triangles touched when it was encoded (`None` for the types that paint everywhere, and when the shading has a `/Background`), so the renderer samples a texture there alone and skips a mesh with nothing on the canvas; (36) a mesh shading's pixel whose corner no triangle holds strictly (on an edge two triangles share, or on the mesh's side) takes the triangle that covers its centre, edges included (`Triangle::covers`): testing only the corner left a white seam along every shared edge, and the colour is still taken at the corner; (38) the `/DefaultGray`, `/DefaultRGB` and `/DefaultCMYK` colour spaces of a resource dictionary (ISO 32000-2 §8.6.5.6) replace the device space content selects: with `g`/`G`, `rg`/`RG`, `k`/`K` and `cs`/`CS` (by name, or through a `/ColorSpace` resource that is a device space), and as the `/ColorSpace` of an image XObject, an inline image or a shading painted by `sh` or as a shading pattern (`DefaultColorSpaces`, looked up once per content window in the resources and those they inherit, so a form XObject without a default of its own draws in its page's, as Poppler and MuPDF draw it); a default that is a Lab, Indexed, Pattern or device space, has another number of components or is no colour space is ignored and device colour is drawn as before; device spaces inside other spaces (an Indexed base, a Separation or DeviceN alternate, a Pattern's underlying space), shading dictionaries, masks and transparency group spaces are unchanged, and the decoded-image cache (24) keys a decode by the default it was drawn in. hayro drew device colour as it was, so pages that calibrate it this way (common in PDF/A) came out in the wrong colours; (39) knockout groups (#2971): `Device::set_knockout` right after a `/K true` group is pushed; `Device::knockout_image` for an unmasked image before its group is pushed, when `Device::in_knockout_group`: the device clears its placement rectangle only if it will draw the image (on the canvas, not a preview's tiny image, and it decodes), decoded at its draw size so the draw reuses that decode; and, when `Device::knockout_erase_wanted`, a nested group's content drawn once between `begin_knockout_erase` and `end_knockout_erase` before the group itself, which then always gets a layer of its own; (40) an optional content membership dictionary's visibility expression (`/VE`: `/And`, `/Or`, `/Not`, nested up to 32 deep) decides its visibility ahead of `/OCGs` and `/P` (ISO 32000-2 §8.11.2.2); it was ignored, so content under it stayed visible with its layers hidden; a malformed expression, including one naming an object the document doesn't list in `/OCProperties /OCGs`, falls back to `/OCGs` and `/P` (#2986); (41) a transparency group that is neither isolated nor knockout, entered at full opacity with no soft mask and Normal blending, is drawn straight onto the page instead of into a layer of its own (§11.4.7: its elements composite with the backdrop; the layer made a `/BM /Multiply` highlight appearance an opaque block, #1968); (42) text in a Type 3 font is drawn filled whatever the text rendering mode, except mode 3 (invisible): only that mode has any effect on Type 3 fonts (ISO 32000-1 §9.3.6). Stroking ran the glyph procedure a second time, so `2 Tr` made bitmap fonts look bold, `1 Tr` painted an uncoloured glyph in the stroking colour, and `7 Tr` hid it (`7 Tr` since follows 64); (43) Lab colour spaces honour their own `/WhitePoint`: L\*a\*b\* goes to XYZ relative to that white, is Bradford-adapted to D65 and converted to sRGB (ISO 32000-2 §8.6.5.4) instead of through `LAB.icc` as if every white were D50 (a D65 blue came out 45 levels too red; the profile is removed); components normalised to [0, 1] (`manual_scale`, an `/Indexed` palette over Lab) map onto L\* 0..100 and the a\*/b\* `/Range`; (44) a Type 0 font whose `/ToUnicode` is the name `/Identity-H` or `/Identity-V` (not a CMap stream; WSCAD writes it) reads each code as its Unicode value, as Acrobat shows it (`Type0Font::identity_to_unicode`); the identity CMap the name resolved to maps codes to CIDs only, so such pages had no text to select or find; (46) an image XObject's group applies the fill opacity, so the fill alpha is reset to 1 before a stencil mask takes the fill colour as its paint, and a pattern paint drops the opacity it captured at `scn` (`Pattern::without_opacity`) (it was applied twice: a mask at `ca 0.5` was drawn at a quarter, #2975); (47) `path_as_rect`: a five-element path is a rectangle only when its four points are distinct, each step from one to the next runs along a single axis, and the last returns to the first. The length test admits one MoveTo and four LineTo as well as one MoveTo, three LineTo and a ClosePath, and asking only that every corner of the bounding box was visited says nothing about the order or the steps between, so a five-point polyline whose ends reached the corners was painted as that box -- a fourth side the path does not have -- and a clip of that shape was discarded; the coordinates are compared exactly, since the matrix is applied after this check and a `cm` of 10,000 turns `is_nearly_equal`'s 256th of a unit into tens of device units (#3327); (48) an `/ICCBased` colour space is cached by what its profile is read from (`IccProfileKey`): the stream object it names, looked up without reading the stream, and then the stream's dictionary and its own bytes (decrypted, not decoded), so a byte-for-byte copy of a profile in another object is read once, and a profile stream written directly in its array, which reports the object holding the array as every other stream written there does, is told apart by its bytes. hayro keyed it by the stream dictionary's bytes alone, so two different profiles with the same `/N` and `/Length` shared whichever was read first, and colours in the second were drawn through the first. `InterpreterCache::icc_profile_reads` counts the profiles read; (49) `OpenTypeFontBlob::new` also accepts a `post` table version 1.0, 2.0 or 3.0 written with its 16-bit halves swapped (`00 00 00 03`), as ScanSoft PDF Create! embeds every font; such fonts were refused and their text drawn with a substitute (Hebrew came out garbled or missing, #2946); `glyph_names` reads such a table from a copy with the version written correctly, so a 2.0 table's names serve `/Differences`. Any other unknown version is still refused (pdf.js 9462); (50) `CffFontBlob::glyph_index_by_name` looks a glyph name up in a name to glyph map built on first use (shared between clones) instead of searching the whole charset, with a string lookup per glyph, for every character code of a font; the first glyph with a name still wins; (51) at most 4096 graphics states saved at once, holding at most 64 MiB together (each `q` copies the whole state, dash array and clip list included, so short operators multiplied one large state); a `q` past either limit is counted but not copied, and its `Q` still removes the clips added since (from storytold/craft-libs#239); (52) a `/W2` run whose first CID is past `MAX_CID` stops there, as in `/W` (7), checked before the run's metrics are read: a first CID of 4294967295 inserted one entry and then overflowed, discarding the whole `/W2` table (from storytold/craft-libs#254); (55) a Separation or DeviceN tint transform that cannot be read keeps its colour space, and one that cannot be read or evaluated paints the alternate space's initial colour, as evaluation failures already did; that fallback, and a `cs`/`CS` colour space that cannot be read (drawn in DeviceGray as before), are now reported once per content stream as `InterpreterWarning::ColorFallback` (`RenderWarning::ColourFallback` in `pdfcraft-render`) instead of silently (#4260); (56) an annotation whose Invisible flag (bit 1) is set and whose `/Subtype` is none of the standard types of ISO 32000-2 Table 171 (`is_standard_annotation_type`; no `/Subtype` counts as unknown) is not drawn (Table 167), and a `/Popup` annotation's appearance is never painted on the page (§12.5.6.14: a popup has no appearance stream of its own; the viewer shows it as a window for its parent annotation). Both were drawn from their `/AP`; (57) a simple font drawn with a standard-font stand-in because the document names a font it doesn't embed (`StandardKind` with `fallback`) narrows a glyph to a narrower `/Widths` advance but no longer widens it to a wider one: the advance already places the next glyph (ISO 32000-2 §9.2.4; /Widths in Table 109), and widening drew a non-embedded `Arial,Bold` with 600-unit widths as a heavy fixed-pitch face whose `i` and `l` were solid blocks twice their width; an exact standard-14 font still matches its standard metrics both ways; (58) the fallback request for a Type 0 font that is not embedded (`FallbackFontQuery::with_descriptor`) takes its serif, italic and small-cap flags, `/FontWeight`, `/FontFamily` and `/FontStretch` from the descendant CIDFont's font descriptor (ISO 32000-2 §9.7.4.1, §9.7.6.1; §9.8): it read them from the Type 0 dictionary, which has none, so every such request asked for a regular sans-serif face and no resolver could tell a Song or Mincho font from a Hei or Gothic one, or see `/FontWeight 700`; (59) the NoRotate flag (`/F` bit 5) is honoured: the appearance, fitted to `/Rect`, is turned against the page's `/Rotate` about the rectangle's upper-left corner, which stays where it is, so it reads upright as the page is displayed (ISO 32000-2 §12.5.3). Sticky notes, which are saved NoRotate, were drawn turned with the page (#2583). Form fields and links stay in `/Rect`, where PdfCraft takes their click targets from it; (64) text in a Type 3 font follows ISO 32000-2 §9.3.6 in the clipping modes: under `7 Tr` it is not rendered (reported to the device as clipping text, `GlyphDrawMode::Clip`, so extraction keeps it), and in modes 4 to 7 a Type 3 glyph adds nothing to the clipping path (`clip_glyph`), so text shown only in a Type 3 font leaves no clip at `ET`. Since (42) `7 Tr` painted the glyphs in the fill colour (black by default), so a fill meant to follow showed them wherever it didn't cover them; 4 to 6 still render filled; (66) a Separation colour space whose colourant is the special name `All` paints every colourant at once (ISO 32000-2 §8.6.6.4): on screen and in an RGB print raster its tint t is the gray 1 − t, complemented because the device is additive, whatever its alternate space and tint transform say (hayro drew it through the tint transform, so a `/DeviceCMYK` transform giving cyan drew registration marks light cyan); `/None` still paints nothing, any other name still goes through its alternate, and a DeviceN space naming `All` keeps its alternate, since the clause gives the name that meaning in a Separation space; (63) a luminosity soft mask whose group colour space is `/DeviceCMYK` (by name, not an ICC-based or calibrated space) reads a `/DeviceCMYK` fill or stroke colour drawn in it, and its `/BC`, as their gray `1 - min(1, 0.3 c + 0.59 m + 0.11 y + k)` (ISO 32000-2 §10.4.2.3, §11.5.3: device colour converts to gray with no colour calibration; `Context::luminosity_in_device_cmyk`, `color::device_cmyk_to_gray`): it went through the CMYK display profile, where 100% K is a dark grey, so a 100% K mask let about an eighth of the masked paint through. CMYK images, shadings and tiling patterns inside such a mask, and CMYK on the page, still use the profile | (1) `raster::tests::widget_appearance_states`; (2, 3) `xtask text-oracle` on corpus/pdfjs issue918;

(5) `usable_dash_pattern`: a stroke whose dash pattern could cut it into more than `MAX_DASHES_PER_STROKE` (250,000) pieces, counting kurbo's restart of the pattern at every subpath and `ClosePath`, is drawn solid (a fuzzed `/D [[11] 0]` on a line from x = 92234775807 allocated over 5 GB, `[0.000001] 0 d` on a 20 pt line over 10 GB); (6) a dash pattern with a negative or non-finite entry, or a period that isn't positive, is drawn solid (`[-1 -1] 0 d` looped for ever in kurbo); (7) `render_size` and `render_into`: render into a buffer the caller allocates (PdfCraft renders into pixel-aligned memory that the GUI takes over as texture data); `render` is `render_into` on a new pixmap; (8) checked image source/target/RGBA, alpha-premultiplication scratch and intermediate sizes before resampling, finite transforms and exact source/mask buffers; sources wider than u16 may shrink before backend limits, with a 2^20 source-axis cap and conservative 128 MiB filter-planning estimate; an over-limit or failed resize keeps the original image resolution and geometry when the source fits the backend, otherwise skips it, with a logged warning; staging, resampling output/scratch, RGBA conversion and padding buffers use fallible reserves; (9) `may_paint_canvas`: a fill or stroke whose control-point box, grown by how far its paint reaches past the path (half the stroke width times the larger of the miter limit and √2) plus 0.5 user units and 2 pixels, misses the canvas is not drawn, so a tile no longer strokes and fills every path of its page (item 5 of #623); `set_skip_offscreen_paths` turns this off for the regression test; (10) `/Interpolate` governs the pre-resize too (#624): a minified image that does not request interpolation is pre-resized with nearest-neighbour, planned without the Catmull-Rom filter limits (`image_resampling_size` takes the flag); a Type 3 glyph image is sampled bicubically only when interpolated; a minified image with a matching soft mask is nearest-sampled straight into premultiplied RGBA; (11) `may_paint_rect`: an image whose stream-size box, mapped to the device, misses the canvas is skipped before decoding (decoded data can only shrink against that box), so a tile of an image-heavy page no longer decodes, resamples and rasterizes every image on it; (12) preview renders (`InterpreterSettings::preview`: backdrops, thumbnails, grid cells, signature-drag backgrounds) skip images under `PREVIEW_MIN_IMAGE_AREA` device pixels, while final renders always draw them; (13) reading colours (#897): `RenderSettings::color_replacement` takes a `ColorReplacement` (text colour, background, `only_black`, `line_art`) that remaps solid text and line-art paint while rendering, glyph outlines counting as text and stencil-mask ink as line art; images, image alpha masks, soft masks and pattern cells keep their colours; `render_pdf` gains a `color_replacement: Option<ColorReplacement>` argument (pass `None` for true colours); the upstream-only `[dev-dependencies.log]` entry is removed from `Cargo.toml` (log is a normal dependency since the logging patch), so `cargo test -p hayro` runs this crate's unit tests; (14) a shrunk, interpolated, axis-aligned image is snapped to whole device pixels: shrunk once to its rounded device rectangle and drawn 1:1 at the rounded corner, instead of a ceil-sized raster resampled again at a fractional scale and offset (`snap_minified_image`; scans looked soft next to Acrobat); (15) a soft mask of another size than its image is filtered when shrunk, whatever its `/Interpolate` (#1649): such a mask carries the shape on its own (Word saves text as a tiny black image with a glyph-bitmap mask), and nearest-neighbour dropped every stroke thinner than the shrink factor; (16) under a soft mask or a blend mode, axial and radial shadings are sampled instead of drawn as native gradients (#2128): vello_cpu 0.0.8 copies an opaque gradient over fully covered tiles without the mask or blend mode, so PowerPoint's faded gradient fills came out solid; (17) the renderer keeps annotation paints out of the reading-colours mapping between `begin_annotations` and `end_annotations` (#1548); (18) the page renders as one transparency group; under reading colours its background is painted inside it as the initial backdrop, so a Multiply highlight blends with the dark background instead of staying an opaque block, and otherwise the background stays outside, so a blend mode over an empty part of the page keeps its colour instead of blending with the white paper (#2970); (19) `set_paint` samples a mesh shading's texture over its triangles alone (`EncodedShadingPattern::extent`, padded rather than repeated) and skips a mesh with none on the canvas: a BricsCAD plan's 310 one-triangle `sh` each covered the whole tile, 2 s per 1024 px tile at any zoom (the watchdog gave the page up on a busy machine), now about 70 ms; (20) a tiling pattern whose step is too large for a cell pixmap, where what is painted (a fill, or a stroke with its width) can only show the first cell (PowerPoint's `/XStep 2147480100` for a picture fill drawn once), has its `/BBox` drawn at full scale with a transparent border and padded instead of tiled (`shows_one_cell`; a cell whose scale isn't finite and positive, from a `/BBox` too thin to divide by, keeps the old path: `usable_cell_scale`); shrinking the cell to fit the 3000 px limit of (3) left the picture under a pixel, so network diagrams lost their pictures (#3349); (22) knockout groups: while one is innermost, fills, strokes, glyph outlines and shadings are drawn with `Compose::Copy` (weighted by coverage), so each element replaces what earlier elements of the group drew instead of compositing over it; an image or nested group, drawn into a layer of its own, first has what is under its shape cleared (`knockout_image` for an unmasked image's rectangle, only when `draw_image` will draw it, decoded at the size it is drawn; a knockout erase pass that draws a nested group's content with every paint clearing instead of painting, a shading fill's clear clipped to the shading's `/BBox` as its paint is) and then composites over it (#2971); (23) backport of hayro 0.8: shadings that `as_svg_gradient` can represent are painted as a `vello_cpu` linear or two-point radial gradient instead of a texture sampled pixel by pixel through the shading function (InDesign fades are luminosity soft masks of one full-page axial `sh`: 40 on a report page took 15 s at 144 dpi, now under 1 s); without upstream's half-pixel shift, which suits vello_cpu 0.3 but moves 0.0.8's gradients off pixel centres; (25) a tiling cell is drawn at the scale that makes one `/XStep` (`/YStep`) exactly the cell pixmap's whole number of pixels (`tiling_cell_pixels`, at least 1 and at most the cap), so the repeated pixmap puts cells at whole multiples of the step at any device scale; drawing at the unrounded scale repeated the cell up to half a pixel off at every step, and the error grew with distance from the pattern's origin (ISO 32000-2 8.7.3.1) | (1) `raster::tests::tiles_match_full_render`;

+| hayro-syntax | 0.7.2 | Apache-2.0 OR MIT | (1) Page-tree cycle guard in `resolve_pages` (visited set + depth cap): a `/Kids` loop among compressed objects overflowed the stack and aborted the process; (2) `ccitt_size_ok`: CCITT images wider than 2^20 columns or over 2^28 pixels are not decoded (a fuzzed `/Columns 4294967295` allocated 4 GiB); (3) Flate/LZW predictor row widths are saturating `usize`, a zero width is refused and a row longer than the data is not allocated (a fuzzed `/Columns 9223372036854775807` wrapped to a 2^61-byte allocation and aborted); (4) the inline-image end-of-data check (`EI`) doesn't nest inside its own look-ahead and examines at most 256 candidates and steps (50 images with "EI" in their data ran for over ten minutes); an EI followed by a delimiter (EI%..., EI[...) ends the image like one followed by white space; only a regular character after EI skips the candidate; (5) a stream whose `/Length` is wrong is recovered only when `stream` is the next token — scanning ahead to a later object's `stream` made an indirect appearance-state dictionary (Quartz checkboxes: `/AP /N` → `<< /Yes … /Off … >>`) render as a non-form, so the widget was skipped; (6) JPX rescaling uses an exact integer sample range for 1–32-bit components (32 shifted past u32, and floating-point maxima at 25–31 bits wrapped to zero), and refuses zero-sized rows; (7) `decode_limit`: Flate (through flate2 and the fallback inflater), LZW, RunLength and ASCII85 never write past `MAX_DECODED_STREAM` (256 MiB), or, for the last filter of an image of known size, past twice its pixel bytes (a predictor tag byte per byte), at most 1 GiB; `Stream::decoded_within` for budgeted callers; a page's `/Contents` array shares one `MAX_DECODED_STREAM` (a 2 MB page whose content stream or 8 × 8 image inflated to 2 GB took the renderer past 3 GB in under a second; naming the stream twenty times in `/Contents`, 5 GB); (8) high-precision numbers (jsPDF MediaBox coordinates with over 19 digits) parse without overflowing the u64 mantissa: fractional digits past it are dropped, integer digits past it scale the value (a real, kept finite); (9) large dictionary indexes are built on first use and shared across repeated reads within each PDF (#307); the validated-byte cache is bounded, reader contexts remain separate, repairs and inline/content dictionaries bypass sharing, and small dictionaries stay eager; (10) decoded object-stream slots publish once under contention, cold loading rejects recursive dependencies, and xref repair serializes without holding recursive read guards; this permits one parser per native render pool with private worker caches; (11) `sync.rs`: a poisoned lock is recovered instead of unwrapped (a worker panic no longer cascades into every reader of the same PDF), and xref repair takes a blocking write lock instead of asserting a non-blocking one; (12) `SegmentList` (`util.rs`) returns `None` for an out-of-range index instead of panicking; (13) a page's `/UserUnit` scales `render_dimensions` and `initial_transform`, so the page and everything on it are sized in points, as Acrobat shows them; it is read as Acrobat reads it (the page's own entry, not inherited; a number from 1 up, at most 75,000; anything else counts as 1), and a page without it keeps exactly the transform it had; (14) revision 2–4 passwords are tried as given and then in PDFDocEncoding (`legacy_passwords` in `crypto/mod.rs`, which resolves the upstream `TODO: Convert to PDFDocEncoding`): passwords arrive as UTF-8 text, so a password with characters outside ASCII (`Çok güzel`, `ılık€`) written in PDFDocEncoding, as ISO 32000-2 §7.6.4.3.2 asks and qpdf and Acrobat write it, was always wrong; (15) page content is read a piece at a time (`page::ContentReader`, `Page::content_reader`): plain streams and Flate streams without a predictor are decoded as they are read, with a budget of 64 times their compressed size and never less than `MAX_DECODED_STREAM` (a stream that expands past it is cut and reported); other streams are decoded whole, as before, and share `MAX_DECODED_STREAM`. The content tokenizer reads a window at a time (`UntypedIter::new_window`, `TypedIter::needs_more`, `TypedIter::committed`): an instruction that runs past the window is not decided until more data follows, which `Reader` records by flagging reads and `at_end` past the end of the data, including through the clones the parser makes. The Flate decoder keeps its own 32 KiB history, so it pauses at any output size. `ContentReader::new` reuses raw/decrypted stream bytes for budget accounting and piece creation, and `decoded_raw_within` applies the existing Whole-stream filters and limits to those bytes without decrypting twice; (16) revision 5–6 (AES-256) passwords are tried in their SASLprep form (RFC 4013, then UTF-8, at most 127 bytes, as ISO 32000-2 §7.6.4.3.3 Algorithm 2.A asks and pdfcraft-crypt writes them) and then, if that differs, as given (`aes256_passwords` in `crypto/mod.rs`, which resolves the upstream `TODO: Do the above.`; `stringprep`, already in the tree through pdfcraft-crypt, is an optional dependency enabled by `std`, and without `std` passwords are used as given): the renderer used the password as typed, so one that SASLprep changes (a decomposed `café`, a no-break space, the fullwidth `ａｂ` a Japanese IME types in full-width mode) was wrong, although pdfcraft-cos accepted it: protecting a document with such an open password was rolled back ("the password is incorrect"), and a file with such a password did not open with it.; (17) CCITT `/Rows 0` means the height is not predetermined (ISO 32000-2 Table 11), not zero rows: scanned Group 4 pages written that way rendered blank; (18) The streaming Flate decoder (`lzw_flate::flate::fallback`) copies a back-reference in runs of up to its distance (`extend_from_within`), not byte by byte. The copy reads only bytes already in the output, and a copy whose source does not exist still writes nothing, so the bytes are those a byte-by-byte copy writes. Inflating the A1 sample's content stream (278.6 MB) takes about 14% less time (0.66 s to 0.56 s); the output is identical; (19) CCITT `/Rows` below the image's `/Height` decodes to the height: a plotter driver wrote `/Rows` equal to `/Columns`, so only the first rows were decoded and the rest drawn black (#3308) (20) `stream` followed by spaces or tabs and then the line break (`stream \r\n`, as Microsoft Reporting Services writes it) starts the data after the line break; the content stream was taken to start at the space and the page rendered blank.; (21) a JP2 colour specification naming an enumerated colour space the decoder refuses (CIEJab in a veraPDF fixture, YCbCr, PhotoYCC, YPbPr, bilevel…) no longer fails the image: it is decoded again from a copy whose `colr` names the space the decoder assumes without one, greyscale, sRGB or CMYK by component count, as MuPDF and Poppler draw it (`without_refused_enumerated_colour`; the page drew blank, #3306); (22) an object stream's index of `objnum offset` pairs is parsed once per stream and kept beside its decoded data (`ObjectStreamIndexes`, `XRef::with_object_stream_indexes`), and an offset past `usize` is malformed instead of wrapping: `XRef::get_with` parsed the whole index again for every object it fetched from the stream, so reading all of a stream of N objects took N² steps (a Firefox page whose 65,542 objects share one stream took 37 s to draw and 40 s to extract its text); (23) the inline-image end-of-data look-ahead no longer rejects a candidate `EI` because a byte above 0x7F lies between it and the next one: when the candidate is the end, those bytes are the content stream that follows the image, and its strings carry such bytes (WinAnsi `(Grüße) Tj`, the two-byte codes of any Type 0 font), so the operator check that follows decides alone, bounded as in (4) (a scanned page whose OCR text held an accented word and a later capital "EI" — EINGANG, BEI, KLEIN — drew and extracted nothing after the image: 40 of 275 pages across five real documents); (24) `xref::prev_offset`: a trailer `/Prev` written as a reference `N G R` is read as the offset that object holds when the section's own entries place it (iText's `indirectPrev.pdf`; each section's entries are read before its `Prev` is followed), and otherwise as offset N (tiff2pdf; JHOVE's PDF-HUL-157 files, #2366), as `pdfcraft-cos` and other readers take it, so the earlier sections' pages are seen instead of one; (25) direct arrays and dictionaries share a reader-local nesting cap of 128, counted while skipping and while parsing a dictionary (its lenient repair reads, rather than skips, an object found where a key belongs, so `<< << …` recursed through that read); deeper objects return `None` instead of overflowing the stack (including unused trailer values, trailer entries, content operands and marked-content properties); a chain of 65 direct stitching functions now stops at this cap, before the 64-function guard; (26) an xref stream subsection must be backed by its decoded data: all-zero `/W` widths (an entry reads no bytes) and a declared count longer than the data are refused before any entry is inserted, where a tiny stream with a large `/Size` or `/Index` count inserted that many entries (from storytold/craft-libs#239); a subsection running past object number `i32::MAX` is refused instead of overflowing or turning negative; (27) an xref stream's type field is read big-endian at its full `/W[0]` width, where only its first byte was read and wider fields shifted every later entry, and `/W[0]` over 8 bytes is refused like `/W[1]` (from storytold/craft-libs#241); (28) a content instruction keeps up to 256 operands (`MAX_OPERANDS`) instead of 10, and past that drops the oldest instead of ending the content stream: the eleventh operand of a twelve-ink DeviceN `scn` (ISO 32000-2 §8.6.6.5 allows any number of components) blanked the rest of the page (#4260) | (1) `cos/tests/writer.rs::page_tree_loops_in_object_streams_do_not_crash_readers`;

 | winit | 0.30.13 | Apache-2.0 | (1) on Windows 11 (build 22000 and later), `WM_DPICHANGED` applies the rect Windows suggests. It used to nudge the window onto the monitor `MonitorFromWindow` names, which during a drag is still the monitor being left; the nudge sent another `WM_DPICHANGED`, so a window dragged to a monitor with another scale factor grew and stayed on the wrong monitor at the wrong scale (#324). Backport of winit master 488c036a ([winit#4341](https://github.com/rust-windowing/winit/pull/4341)), which no 0.30 release has; Windows 10 keeps the old adjustment, as on winit master. (2) on Wayland, a seat's text input is destroyed when the seat goes away, not whenever it loses a capability: losing any capability (a touch screen or tablet unplugged, a remote-desktop session ending) destroyed it, and only an added capability recreated it, so IME stopped working until restart. Port of [winit#4747](https://github.com/rust-windowing/winit/pull/4747); (3) on Windows, an IME composition reports its cursor from `GCS_CURSORPOS` only when `WM_IME_COMPOSITION` says it is set, and at the end of the composition otherwise: the Microsoft Korean IME never sets it, so the cursor read as 0 (egui then drew no caret while composing; it now draws it after the syllable). Port of [winit#4746](https://github.com/rust-windowing/winit/pull/4746); (4) on Windows, a hidden window is not maximized until it is shown, and a hidden window shown while maximized gets one `ShowWindow(SW_MAXIMIZE)`: `SW_MAXIMIZE` shows a hidden window, so PdfCraft, which eframe keeps hidden until its first frame is drawn, appeared unpainted (white) when it restored a maximized window, and could lose its focus. Port of [winit#4587](https://github.com/rust-windowing/winit/pull/4587) (the later, focus-safe form of [winit#4575](https://github.com/rust-windowing/winit/pull/4575)); (5) on X11, when allowing or disallowing IME replaces the focused window's input context (egui does it each time a text field gains or loses focus), the new context is focused: no focus event follows, so it stayed unfocused until the window lost and regained focus. Port of [winit#4727](https://github.com/rust-windowing/winit/pull/4727); (6) on macOS, `insertText` commits through IME when a composition was started (`pending_commit`, set by `setMarkedText`) rather than when marked text is left: input methods that end a composition with `unmarkText` before `insertText` lost the text, and Apple Korean dropped the key typed after a syllable (`한` then `5` or `;`); other `insertText` calls stay `KeyboardInput`; a commit outside a key press (a candidate clicked with the mouse, dictation) clears the marked text and leaves no key to swallow, as in [winit#4748](https://github.com/rust-windowing/winit/pull/4748) (without it the next key, such as Backspace, was lost). `validAttributesForMarkedText` lists the underline and marked-clause attributes, without which some input methods don't compose. Port of [winit#4650](https://github.com/rust-windowing/winit/pull/4650), the 0.30 backport of [winit#4651](https://github.com/rust-windowing/winit/pull/4651) (merged on winit master), with the underline attribute spelled as AppKit's `NSUnderlineStyleAttributeName` (`NSUnderline`); (7) on macOS, disallowing IME with a composition in progress (focus leaving a text field) tells the input method to discard its marked text (`discardMarkedText`): it kept composing it once IME was allowed again, so the abandoned syllable came back (`하`, then `가` typed in the next field, became `학`, then `하` + `가`; Japanese `か` then `さ` became `傘`). Port of [winit#4745](https://github.com/rust-windowing/winit/pull/4745); (8) on macOS, text inserted outside a key press without a composition (the emoji picker) is reported as `Ime::Commit`; it was dropped. Port of the emoji-picker part of [winit#4749](https://github.com/rust-windowing/winit/pull/4749) (0.30 backport of [winit#4748](https://github.com/rust-windowing/winit/pull/4748)); its `selectedRange` change for dictation is left out because it switches on press-and-hold for every held key (an accent menu instead of key repeat, and the chosen accent added after the repeated letters); (9) on macOS, a key whose text was committed through IME isn't also sent as `KeyboardInput` unless AppKit forwards it as a command (Enter): Apple Korean answers Space with no syllable in progress with `setMarkedText(" ")`, `insertText(" ")`, `setMarkedText("")`, and the last call reset winit's state, so the space arrived twice. Same goal as [winit#4478](https://github.com/rust-windowing/winit/pull/4478), whose changes don't reach this call order (macOS 14); to be proposed upstream there; (10) on macOS, when the first key in a fresh app reaches Apple Korean's `insertText` as a raw compatibility jamo instead of starting a composition, that key is interpreted once more, synchronously, before it is sent as `KeyboardInput` (g k s typed ㅎㅏㄴ instead of 한); only an unmodified, non-repeated first key whose one callback inserts that same jamo, with IME enabled and nothing composed, focus and input source unchanged, is retried (`ime_startup.rs`). Port of [winit#4744](https://github.com/rust-windowing/winit/pull/4744), with its policy tests.; (11) on X11 without `Xft.dpi`, the scale factor comes from the X screen's configured DPI (its size in pixels and millimetres) before the output's physical density from RandR: Xorg can deliberately run a dense panel at 96 DPI, and only winit applications then looked zoomed; `Xft.dpi` still wins, `WINIT_X11_SCALE_FACTOR` still overrides, and a screen reporting no size keeps the RandR fallback. PdfCraft patch (#1150, replacing the launcher pin proposed in #908). (12) on macOS, `WinitView` answers `mouseDownCanMoveWindow` with the window's `movable_by_window_background` attribute (NO unless asked): NSView answers YES for a view that isn't opaque, so with the transparent title bar and full-size content view PdfCraft uses, AppKit moved the window for any drag that began in the 28 pt title-bar band before the app saw it, and document tabs (which live in that band) could not be dragged to reorder them. The empty strip still moves the window through `ViewportCommand::StartDrag`. PdfCraft patch. The published crate's asset files (`docs/res/*.svg`, `examples/data/*.png`) are left out, so its `window` example doesn't build; (13) on Wayland, pixel-only wheel, wheel-tilt and continuous-source scroll events report `Moved` rather than starting an unterminated finger gesture, so egui follows modifier release instead of keeping Ctrl zoom latched (#991). Finger gestures and unknown sources retain their existing phase policy | (1) `pdfcraft` `tests::winit_carries_the_windows_11_monitor_scale_fix` keeps the patch in the build; the drag itself needs two monitors with different scale factors on Windows 11; (2) `pdfcraft` `tests/winit_wayland_text_input.rs`; the capability change itself needs a Wayland session and an input method; (3) `pdfcraft` `tests/winit_windows_ime_cursor.rs`; composing itself needs the Microsoft Korean IME; (4) `pdfcraft` `tests/winit_windows_hidden_maximized.rs`; the start-up itself needs Windows and a window that was closed maximized; (5) `pdfcraft` `tests/winit_x11_ime_focus.rs`; switching fields itself needs an X11 session and an input method (IBus, fcitx5); (6) `pdfcraft` `tests/winit_macos_ime_commit.rs`; composing itself needs macOS and an input method; (7) `pdfcraft` `tests/winit_macos_ime_discard.rs`; composing itself needs macOS and an input method; (8) `pdfcraft` `tests/winit_macos_emoji_picker.rs`; the picker itself needs macOS; (9) `pdfcraft` `tests/winit_macos_korean_space.rs`; composing itself needs macOS and Apple Korean; (10) `pdfcraft` `tests/winit_macos_korean_first_key.rs` and `ime_startup.rs`'s own tests (run them with `rustc --test`); typing itself needs macOS and Apple Korean; (11) `pdfcraft` `tests/winit_x11_dpi.rs` keeps the patch in the build, and `util::randr` tests the policy (run them in the vendored crate); the scale itself needs an X11 session; (12) `pdfcraft` `tests/winit_macos_title_bar_drag.rs` keeps the patch in the build; the drag itself needs macOS and a pointer; (13) `pdfcraft` `tests/winit_wayland_scroll.rs` compiles the production phase policy and exercises modifier release through egui; live COSMIC confirmation remains open |
-| egui-wgpu | 0.36.2 | MIT OR Apache-2.0 | (1) `winit::surface_fit`: a window's surface is configured within the device's `max_texture_dimension_2d`, both sides shrunk by one factor that egui then draws at (`pixels_per_point × render_scale`), so the whole window is drawn into the surface (on DX12 it is stretched over the window and lines up with the pointer; wgpu's GL backend copies it unscaled into a corner); the longer side becomes exactly the limit; the depth and MSAA textures follow, and a recreated surface starts again from the window's own size. egui-wgpu configured the window's size as is, and `Surface::configure` panics beyond the limit: a window restored at another monitor's scale (opening an Outlook attachment on a mixed-DPI laptop asked an 8192-pixel device for 8600 × 3423, #577) or stretched across monitors closed PdfCraft, before its window appeared when it happened at start-up ([emilk/egui#8361](https://github.com/emilk/egui/issues/8361)).

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+A lightweight PostScript scanner.
+
+This crate provides a scanner for tokenizing PostScript programs into typed objects.
+It currently only implements a very small subset of the PostScript language, 
+with the main goal of being enough to parse CMAP files, but the scope _might_
+be expanded upon in the future.
+
+The supported types include integers and real numbers, name objects, strings and arrays.
+Unsupported is anything else, including dictionaries, procedures, etc. An error
+will be returned in case any of these is encountered.
+
+### Safety
+This crate forbids unsafe code via a crate-level attribute.

+/*!
+A lightweight PostScript scanner.
+
+This crate provides a scanner for tokenizing PostScript programs into typed objects.
+It currently only implements a very small subset of the PostScript language,
+with the main goal of being enough to parse CMAP files, but the scope _might_
+be expanded upon in the future.
+
+The supported types include integers and real numbers, name objects, strings and arrays.
+Unsupported is anything else, including dictionaries, procedures, etc. An error
+will be returned in case any of these is encountered.
+
+## Safety
+This crate forbids unsafe code via a crate-level attribute.
