Deleting one word from a recognised line covered the whole line and
redrew it in Helvetica, though nothing but that word had changed.
A text edit of an OCR phrase now covers and redraws only the words it
changes; the rest stay as the scan shows them, still invisible text. Each
changed stretch is rewritten as a phrase of its own, on a copy of the
document, and the edit falls back to the whole-phrase rewrite when words
can't be told apart or a kept word would move. A deleted word leaves its
gap. A replacement a little too wide is squeezed across to fit, by up to
a quarter; wider than that it takes over the next word. A change of
formatting, or a typed line break, still redraws the whole phrase.

Refs #5989. Ctrl/Cmd+A selects every object on the page; copied objects paste as page content that draws the same, within a document or into another, with organize's bounded deep copy across documents. Headless: object_copy, object_paste, object_move all.
The source shaper refused any Thai text in a program without GPOS mark
positioning, so a row of Thai digits failed although nothing in it is set
on a base. Require the positioning only for text with a vowel or tone
mark, or Sara Am.
Edit text queued Prepare grouped text for every page that came into view, after a full
preparation on a copy of the document on the UI thread to see whether it could. Scrolling cost
that work per page, marked the document changed, added undo steps and inlined shared forms
although nothing was edited.
Now nothing happens while pages are shown. A click (press and release, no drag) on grouped
artwork, routed to the picture by the page router as before, asks once whether that artwork
shows text preparation would open (text::forms::grouped_text_at, which reads the page without
copying or changing it). If it does, the page is prepared as one undoable step and the
paragraph at the point clicked opens for typing. A logo or a group preparation would refuse is
selected as before, with no message and no change. A drag still moves the selected group, and
while a paragraph is open or an edit is waiting the click selects as before. text_prepare is
unchanged.
The docs and the parity entry no longer say text is prepared on entering Edit text.

- A kid's name repeats its parent's, so one long name over 20,000 kids came to 80 MB; the walk now stops at 4 MiB of names and counts the rest as unread
- Cover the widget written into a shared /Kids array and the field cap among kids, which no test caught

* M9: refuse a new signature field the field walk can't read back

* M9: comment and content edits keep typed values drawn too
- An edit to one page's comments or content that changes a signature's state moves no page, so the values still waiting on their pages stay pending, as after a form edit.
- The pending-value test runs a field deletion and a comment after a fill, under a certification that allows the fill; its messages say what it checks.

* M9: signed fields behind kids without a name count
- A kid with no /T but kids of its own is walked as a field node, so a signed field under it is listed by its full name.
- An unnamed kid claiming a signature its field doesn't have cuts the walk short, so the document stays signed and keeps its unread-fields row.

Recognize text sizes each word from its own box and a guess at how much
of the em its letters fill, so one phrase's words come out several
points apart (9 to 15.6 pt on a LaTeX scan). Editing a phrase drew and
saved every word at its own size.
An invisible block's size is now the median of its words' sizes
(TextBlock::phrase_size). The styled rewrite draws every run at it and
scales each word's width calibration by its own size over the phrase's,
so words keep the width the scan shows them at; the single-style
rewrite (a new family or bold) uses it in place of the first word's
size; and the inline editor lays each word out at it while typing.

Change:
- Leave a form found to be artwork, or refused for a reason in the form
itself, out of later preparation passes, so a page with many logos or
unsupported groups no longer reaches the 64-placement limit and prepares
nothing. ungroup_ops now marks each refusal as intrinsic or contextual;
contextual ones (translucency, the resources it would merge into, pattern
placement, the decode budget) are re-evaluated where the form appears, so
a form refused in one place is still prepared where a parent draws it.
- Refuse a page-level Do with an operand too many for that placement only:
the form found by its first operand may not be the one drawn. Check a
form's own operand counts before the nested walk, as an intrinsic refusal.
- Use the Windows PUA alternates only when every kept alternate whose code
the PDF's map names a Thai character names that alternate's base
character, so alternates in another order that the map reveals are refused.
Chores:
- Say that the font program confirms each recovered glyph's advance class,
not its identity, and document the alternate check.
Validation: with and without craft-fonts, fonts 105 (+3 build-input), edit
468, engine 482 (+28 integration) and automation 50 + 352 passed; editor flows
248 passed. Formatting, strict Clippy, layers, assets and parity passed; the
wasm check was not run locally. Each new regression failed with its fix
reverted. Real-PDF edits on Royal Gazette 26288 kept their source fonts.
Add:
- Report text grouped more than eight levels deep instead of leaving it
silently grouped, and refuse forms whose resource-naming operators carry
surplus operands, which would otherwise lose nested artwork when inlined.
- Return the applied preparation's own counts from Session::prepare_text, so
text_prepare no longer reports a separate preview's.
- Shape a THSarabunPSK program that has its own Thai mark positioning by that
layout, in its own codes. A span the subsets can't show in place is shaped
whole, Latin rows included, by a complete program of the same face and style,
such as a CFF face from Load font.
Change:
- Expand only forms that show text, directly or through nested forms; image-
and vector-only forms stay grouped and uncounted. Match a Do's raw resource
name bytes, and refuse RGB-blended groups on pages naming no blending space.
- Check the recovered THSarabunPSK map and the Windows PUA alternates glyph by
glyph against the subset's advances, leave dropped glyphs unmapped, and
insert the repair after the last endcmap.
- Shape a Thai run split across same-face subsets cluster by cluster and skip
subset glyphs that are empty. Take the legacy path only for programs in the
legacy glyph order, needing only the glyphs the new text uses.
- Require GPOS mark/mkmk in the script and language system HarfRust selects.
- Match same-face candidates by weight and slant from the name, descriptor
weight or a non-zero ItalicAngle; the Italic flag alone is ignored, as
exporters set it on upright faces. Never complete bold or italic text with
the Regular bundled Thai face.
- Name the missing character, or the unavailable builtin:thai choice, in errors.
Chores:
- Document text_prepare's fields, builtin:thai, the app's refusal reporting
limits and the new routing; extend the text-edit parity evidence. Tests that
need craft-fonts now say they skipped instead of returning silently.
Validation: with and without craft-fonts, fonts 105 (+3 build-input), edit

wasm check was not run locally. Each new regression failed with its fix
reverted. Real-PDF edits on Royal Gazette 26288 kept their source fonts.
Add:
- Prepare supported Form placements as original page operators through the
existing-text UI and text_prepare, with shared-form isolation and undo/redo.
- Repair narrowly identified Thai exporter maps on copied page fonts, recording
repairs without changing the embedded source glyph programs.
Change:
- Reuse legacy Thai Regular/Bold glyph codes and same-face punctuation subsets;
retain point size, spacing, horizontal scale, rise, colour and paint settings.
- Keep cross-family Thai replacement explicit and write matching bundled Thai
subsets through the existing bounded outline path rather than static embedding.
- Keep replacement-only menu choices out of the source-font preview atlas so
opening an ordinary paragraph does not wait an extra frame for unused fonts.
- Refuse unsafe compositing, tagged or malformed groups, and missing contextual
glyphs without losing the user's document or changing other placements.
Chores:
- Document the editing limits and headless workflow; keep text-edit parity partial.

* Redaction: a pattern nothing paints with any more leaves the page
A tiling pattern's cell is a content stream of its own and can draw
anything, text included. Redacting a shape filled with such a pattern
removed the fill from the page's content -- the page looked right, a
black box -- but left the pattern in /Resources /Pattern, and its cell,
with the text that was under the mark, was written into the saved file
unchanged.
The pass does not enter pattern cells, so it cannot redact inside one.
What it can do is notice that nothing paints with the pattern any more.
The graphics state now carries the fill and stroke pattern a `scn` or
`SCN` selected (and `cs`, `g`, `rg`, `k` and their stroke forms clear
it), every painting operator that survives the rewrite records the
pattern it drew with, and a pattern the page selected but no surviving
paint used leaves the page's resources.
Measured on the report's file:
before applied: 1, (SECRET) in the saved bytes
after applied: 1, no /Pattern on the page, (SECRET) gone
A pattern some surviving paint still uses is kept, and so is its cell:
with two boxes filled from one pattern and only the first marked,
patterns_removed is 0 and the resources keep the entry -- the second box
still shows the word, so it is not a leak.
Report gains patterns_removed.
Fixes#3647.
* Keep a pattern every operator that can paint with it still uses
Two defects CodeRabbit found in the first version of this change, both
of which could remove a pattern the page still draws with.
Pattern use was recorded for path painting only. Text shows with the
fill pattern too -- and with the stroke pattern in the stroking render
modes -- as do image masks and anything a form draws, and a form's
content is interpreted with a graphics state of its own, so a pattern it
inherits is never seen inside it. Content like
/Pattern cs /P0 scn 20 140 100 30 re f BT (KEEP) Tj ET
with the box redacted therefore lost the fill of text still on the page.
Every operator that can paint with the current pattern now records it:
text (except mode 3, which paints nothing, and mode 7, which only
clips), inline images, and image or form XObjects. Only path painting
knows exactly what it drew and whether the paint survived, so the others
are recorded as they are met. That can keep a pattern whose paint was in
fact all redacted, which costs an unused resource entry, while dropping
one something still draws with takes paint off the page.
/Resources /Pattern may be an indirect object, like any value. Reading
the reference itself as a dictionary found none and pruned nothing, so
on such a file the cell -- with the text that was under the mark --
stayed in the saved bytes, which is the leak this change is for. It is
resolved now, and what is written back is a dictionary of this page's
own, so pruning never reaches through a /Pattern dictionary another page
shares.
The controls in the test: without the first fix the surviving text's
pattern is removed (left: 1, right: 0), and without the second the
indirect file prunes nothing (left: 0, right: 1).
* M8: refuse retained unsafe tiling patterns
* M8: guard shared appearances and narrow pattern scans
* M8: update TLS dependencies for new advisories
* Redaction: the comment on prune_patterns said more than the code does
`prune_patterns` drops the `/Pattern` resource entry; the `scn` that selected
it stays in the content, so the page names a pattern its resources no longer
hold. The comment claimed the selector went too (noted in review).
ISO 32000-1 8.6.6.2 makes that operand a key of the `/Pattern` subdictionary,
so the open question is whether a reader stops reading the stream at the stale
name. `a_page_whose_pruned_pattern_is_still_selected_renders` answers it with
the renderer rather than with prose: the redacted page is saved, reopened and
rasterized, and
* it renders with no error and the same 300x300 page box,
* the text written *after* the stale selector is still painted -- which is
exactly what a reader would drop if it gave up at the bad operand,
* the redaction overlay is black over the box the pattern filled.
Control: with the drawing after the selector removed, the pixel assertion fails
("the text after the stale selector is still painted"), so it is reading that
text and not a stray pixel.
The selector is left in place rather than cut out: removing operators is a
rewrite of the content this pass does not otherwise do, and nothing surviving
paints with that colour. `pdfcraft-render` is a dev dependency of this crate
only -- layer 4 on layer 3, which the layering allows.
* WIP: pattern guard depth bound sized from the interpreter's
* Pattern tests: keep the guard's cases reaching the guard now a hit path is removed whole
* Pattern automation tests: keep the pattern in use where they test the guard, since a hit path is now removed whole
* Redaction: a form without resources keeps the page pattern it still paints
A form with no /Resources of its own paints with its caller's patterns, but
its surviving pattern paint was recorded only in the form's own output and
never reached the page. With the page's own fill under the mark removed
whole, prune_patterns then dropped /P0 from the page while the form outside
the mark still painted with it, so that fill lost its paint in the saved file.
Pass the painted names up from a form that inherits its caller's resources.
Only the painted side goes up, so this can keep a pattern, never prune one.
* Redaction: a pruned pattern does not stay named by the page tree
prune_patterns writes only the page's own /Resources, and the guard walked
only pages' effective resources. A /Pages node that still named the pruned
pattern kept its cell reachable from Root, so a full save wrote the cell,
text included, while apply returned Ok. Three shapes did it: a page with no
/Parent inheriting from the root, a /Parent that disagrees with the /Kids
tree, and a root /Resources shadowed by a nearer holder that was retired.
Patterns pruned from a page are now unlinked from page-tree holders no page
inherits from, as unlink_doomed does for XObjects, when every /Parent agrees
with the tree. Whenever a pattern was pruned (or a selected page had any),
the guard also inspects the /Resources of every /Pages node Root reaches
down /Kids and up each page's /Parent chain, so whatever stays reachable is
proven safe or the redaction is refused, leaving the document unchanged.
* Redaction: a Type 3 glyph without resources keeps the page pattern it paints
A Type 3 font with no /Resources looks the names in its glyph descriptions
up in the resources of the page or form showing it, so a glyph outside the
mark can paint with the page's pattern. Text recorded only the fill and
stroke pattern of the graphics state, so with the page's own fill under the
mark removed whole, prune_patterns dropped the pattern and the glyph lost its
paint. Showing such a font now keeps every pattern of the scope, as a form
without /Resources keeps what it paints.
* Redaction: say what text-recorded pattern use keeps
Text, inline images and XObjects record their pattern before the hit test,
so a pattern painted only by redacted text keeps its cell. The guard refuses
a cell with text or images; a vector-only cell stays in the file. The comment
said this cost only an unused resource entry. Pin the behaviour in a test.
* Redaction: the page tree is followed up every /Parent link
A full save writes every node a /Parent link reaches, but the guard followed
/Parent only from pages and stopped at the first node it had already seen,
and unlinking never followed it. A /Pages node reached only through the
/Parent of a /Kids node -- a root /Pages with a /Parent, or an intermediate
node whose /Parent leads out of the tree -- kept naming the pruned pattern,
and its cell, text included, stayed in the saved file while apply returned
Ok.
The guard now follows /Parent from every node it visits, page or /Pages, with
the same seen-set against cycles. Unlinking treats a root with a /Parent as an
inconsistent tree, like a disagreeing link, and leaves the decision to the
guard, which inspects every node those links reach and refuses an unsafe
cell.
* Redaction: a long page tree does not exhaust the pattern guard's budget
The page-tree walk counted every node, pages included, against the guard's
16,384-object budget, so redacting a pattern page of a 17,000-page document
was refused with a limit error where it had applied before. Only the holder
nodes the guard inspects count against that budget now; the walk itself is
bounded at a million nodes, as unlink_doomed bounds the same tree.
* Redaction: a Type 3 font set by an ExtGState or shown in a form keeps the page patterns
The resourceless Type 3 check covered only a font set by Tf in the scope that
paints. A Type 3 font without /Resources set through an ExtGState /Font entry
was not flagged, and a glyph shown inside a form with /Resources of its own
recorded its patterns in the form's scope, which the page never saw. In both
cases the page's own fill under the mark was removed whole, prune_patterns
dropped the pattern, and the glyph outside the mark lost its paint.
An ExtGState font is now checked the same way, and a glyph shown in any
nested form marks the page as keeping every pattern it selected. This can
only keep patterns; whatever is kept is checked by the guard.
* Redaction: a pruned pattern a full save would still write is proven safe or refused
The walks that check retained pattern cells follow the references they know
-- resource categories, the page tree, appearances -- but a full save writes
whatever the trailer reaches by any reference. A direct /Parent dictionary, a
/Kids array on a page, or a stray resource entry (/Shading naming the pattern
stream) kept a pruned cell, text included, in the saved file while apply
returned Ok.
pdfcraft_cos gains reachable_objects, which runs the same breadth-first walk
write_full uses (factored out as full_save_order, so the two cannot drift).
Before apply succeeds, every pruned pattern that walk still reaches is
inspected like a retained cell: vector-only passes, anything else refuses
with the existing pattern error. It runs only when a pattern was pruned and
costs one walk of the reachable objects.
* Redaction: a direct /Parent dictionary is part of the page tree too
A /Parent given as a dictionary rather than a reference is written inline by
a full save, but the page-tree walk followed /Parent only as a reference, and
unlinking took such a tree for consistent. A root /Pages whose direct /Parent
held /Resources naming the pruned pattern kept its cell in the saved file.
The guard now walks a direct /Parent like any node (its /Resources, /Parent
and /Kids), and unlinking counts any /Parent that is not the reference /Kids
came from as an inconsistent tree, leaving the decision to the guard.
* Redaction: page-tree walks queue each node once and borrow /Kids
On a hostile tree whose /Pages nodes share one long /Kids array, the guard's
page-tree walk and pattern unlinking pushed every /Kids entry of every node
before checking whether it had been seen, and copied the array on each
visit. Both now queue only nodes not seen yet and read /Kids in place;
unlinking also stops at the first node reached twice, since its /Parent can
agree with at most one of the nodes above it, and leaves that tree to the
guard.
* Redaction: a Type 3 font with /Resources null is resourceless too
/Resources null is the same as no /Resources, but the check counted any
entry, so such a font's glyph outside the mark lost the page pattern it
painted with. A Type 3 glyph shown by a kept annotation appearance is a known
limit, pinned as an ignored test: appearances are not interpreted for pattern
use, and under ISO 32000 the glyph resolves in the appearance's own resources.
* Redaction: a pruned pattern is recorded along its whole reference chain
A pattern name can lead to a reference-valued object whose value is the cell
(/P0 7 0 R, object 7 being 6 0 R). Pruning recorded only object 7, so the
reachability backstop checked an object nothing reached while a stray
reference kept the cell, object 6, in the saved file. Every object along the
chain is recorded now, bounded like the other walks.
* Pattern tests: pin the file identifier where two saves are compared
main now gives a redacted rewrite a new identifier from fresh entropy, so an
incremental and a full save after Apply differ in /ID alone. The test that
checks they are the same save passes fixed entropy to both.
* Redaction: replies and pop-ups removed on other pages feed the shared-appearance check
Apply checks every page for retained unsafe pattern cells when a removed
annotation's appearance is shared with one that stays on an unselected page.
Only annotations removed under a mark fed that check. Replies and pop-ups
that go with them in step 2b (removed_everywhere), often listed on another
page, did not, so a text-bearing cell in an appearance a kept annotation
shares with them escaped the all-pages check and Apply returned Ok.
Their appearance references now go into removed_appearances too, with the
same limit. Raised by FredApps' review of the rebase.

* M10.20: plan Unicode text for OCR output in Type3 faces (fonts, edit)
OCR output used to flatten every character beyond WinAnsi to a silent `?`. This
adds the two pieces that let the OCR layers write the recognized words as they
are; the OCR code that uses them follows in M10.21.
pdfcraft-fonts
- `TextPlan::for_words` maps each word to the standard Helvetica when WinAnsi
covers it, else to Type3 fonts drawn from the craft-fonts faces (the Japanese
document face first, then the rest of the build input). Characters no face
has a glyph for are counted (`missing`), never dropped silently. At most 240
characters per font and 2400 per plan, so one hostile word cannot balloon.
- Which face has which character is asked once per (face, character) for a plan,
not once per word.
- `face_has`, `craft_glyph`, `win_ansi_char`, `fits_win_ansi` are public for it.
pdfcraft-edit
- `add_type3_fonts` / `stamp_with_fonts` register a plan's fonts on a page under
a free `PCOcr`, `PCOcr1`, ... name, build each font once and share the object
with later pages. A shared face is registered under a free name on a later
page that already has a font of the name it was given first, instead of
replacing that page's own font.
- The fonts carry real advances and a ToUnicode CMap, so extraction reads the
text back.
pdfcraft-redact
- A test shows a hand-built Type3 text layer (the shape the OCR output writes) is
redacted like any other text and the verifier passes.
Tests: pdfcraft-fonts 62 passed, pdfcraft-edit 129 passed, pdfcraft-redact 33
passed; clippy -D warnings clean on the three crates. The name-reuse and the
redaction tests build their fonts by hand, so they run without the craft-fonts
build input; the tests that plan real faces skip without it and were not run in
this commit's own check.
* M12: give the hostile-XFA open test more room on a loaded machine
The test opens a form whose calculate script sets a value 50 000 times, against
the one-second budget of an unasked script and a five-second wall-clock bound
on the open. Both sit close to what a machine running several suites at once
can take, so the test can fail without anything being wrong.
It now runs 20 000 iterations (the total is 19999) and allows 30 seconds, which
still fails for a script that hangs or is not capped. Test-only; unrelated to
the OCR work in this series, so it is a commit of its own.
Tests: both hostile_xfa tests in pdfcraft-engine pass.
* M10.21: pluggable OCR engines, preprocessing, review sessions and the OCR tools (ocr, engine, create, automation)
Scan & OCR gets a second engine, optional raster clean-up, a review step before
anything is applied, editable output and a batch mode, headlessly first: the
interface for them follows in M10.22.
pdfcraft-ocr
- A `Recognizer` trait with two engines: the built-in ocrs (moved out of lib.rs)
and the installed tesseract program, run as a fenced external process: fixed
argv, allow-listed language codes, a private temp directory (mode 0700 on
Unix), 120 s timeout, 64 MiB output cap, 50 000-word reading cap. A location
from PDFCRAFT_TESSERACT is validated (absolute, existing, executable) and an
invalid one fails closed instead of falling back to the PATH. `--list-langs`
and `--version` are read from stdout or, for older versions, stderr.
- Strategies: PrimaryOnly, ConfidenceWeighted (the second engine joins when the
first reading's mean is under 70 or unknown) and a ROVER merge (higher
confidence wins per word; against an ocrs word of unknown confidence a
tesseract word wins only at 70 or more; capped at 100 M comparisons; a failing
partner degrades to the primary with a note).
- Preprocessing: opt-in auto-rotate, deskew, denoise and binarize on the RGBA
raster, each with an exact inverse so word boxes map back to the scan. The
300 dpi normalization the steps are calibrated for runs only when a step is
on: with every step off the render is read as rendered, as before. (Enlarging
a 72 dpi render 4x on its own made the models read "due: €250" as "ue: ?250".)
`OcrImage` is validated by construction (side and 64 MP area caps, checked
before any buffer is allocated, including by the resize).
- Confidence bands (High >= 90, Medium 70-89, Low < 70) drive review.
pdfcraft-engine, pdfcraft-create
- `OcrSettings` gains engine, strategy, the four steps, output mode, region, the
skip flags and the low-confidence threshold; Automatic reads confidence
weighted unless a strategy is chosen.
- A recognition is a session: the document guard refuses a stale result with its
reason, pages can be applied one at a time (the guard is taken again after each
applied page), and applying is one undoable step. A per-language dictionary
(a plain-text file: words added from any document stay on disk after it closes).
- Output is searchable (an invisible layer) or a NEW editable document of visible
text at the recognized boxes (`create::from_contents`); words beyond WinAnsi use
the Type3 faces of M10.20 in both, with the shared plan across pages.
- Engine discovery never blocks the interface: results are cached, a stale
answer is shown while a background probe retries, and the models search and
`--version` are cached. Batch: pages or files that already have text are
skipped unless forced, and inputs sharing a file name are found up front.
pdfcraft-automation
- ocr_recognize (engine, strategy, steps, region, output mode), ocr_words (with a
retained review handle), ocr_review_apply, ocr_dictionary, ocr_status and
ocr_recognize_files. The editable `out` must be a new file inside --root and is
refused for a searchable run (it used to be ignored), two batch inputs of one
file name are refused before anything is read, and the batch folder is checked
for existing outputs.
pdfcraft-ui-egui
- Only what the new API needs: the Recognize Text dialog reads with
`recognizers(&settings)`. `ocr.correct` is registered with its label in every
catalog; the screen itself is M10.22.
Tests: pdfcraft-ocr 78 passed; pdfcraft-create passed; pdfcraft-engine and
pdfcraft-automation 450 passed and 1 failed (the automation lib 17, automation.rs
157, hostile_args 2 among them); pdfcraft-ui-egui lib + ocr + control tests 391
passed; clippy -D warnings clean on the five crates. The one failure is in a
test this commit does not change:
recognize_text_makes_a_scanned_page_searchable fails where the models are
installed (they read "quick" as "auick" at that render size); the roadmap on main
already records it. The real tesseract binary ran in
tesseract::tests::recognize_runs_the_installed_binary (tesseract 5.4.0, PATH).
* M10.22: OCR Verify screen, the Recognize Text options and the interface catalogs (ui-egui)
Scan & OCR ▸ Correct recognized text: a full-window screen where a recognition
is reviewed before anything is applied, plus the dialog and batch options for
the engines of M10.21.
OCR Verify screen
- Four panes: the page list, the source page with confidence-coloured word boxes
(click to select, drag to draw a region), the recognized text, and a zoom plus
word inspector. Corrections commit on Enter (an empty commit removes the word),
Remove/Restore, "+ Dictionary" (a per-language file in the preferences folder,
so a word added from a document stays on disk after it closes), per-word and
per-page Verified, F8 / Shift+F8 walk the low-confidence words, Ctrl+T marks the
page reviewed, Ctrl+Tab moves the pane focus, and review edits undo within the
panel.
- Re-OCR of the whole page or a drawn region. A region re-read moves the review
marks of the words it keeps to their new positions and selects the first new
word; a whole-page re-read clears that page's marks (and the undo brings them
back). The region outline is scaled onto the pane, not mapped through user
space again, so it is right on rotated and cropped pages.
- Accept / Reject per page or whole. Pages accepted one at a time each apply once
(the document guard is taken again after each applied page; an edit made
elsewhere in between is still refused with its reason), and Accept in
searchable mode is one undoable step. Editable mode writes a NEW
`<name>_ocr.pdf` through a save dialog and never the source. A real Cancel
keeps the pages already read.
- The engine and strategy menus disable a choice that cannot run and say why;
the check never waits on a process (a background probe fills a cache), and
choosing Automatic moves "Primary only" to Confidence weighted.
Recognize Text dialog and batch
- Engine, strategy, the four clean-up steps and the skip flags are remembered with
the other choices (a saved Automatic without a strategy reads confidence
weighted). The batch refuses two inputs of one file name and existing outputs
before reading anything, notes low-confidence pages at the settings' threshold,
and its toast has a Cancel (the file in flight finishes).
Catalogs and attribution
- The 90 new interface strings are in all 21 catalogs (the Lithuanian ones were
written without native review, and the Bulgarian ones avoid U+045D, which the
bundled monospace face lacks). ATTRIBUTION.toml carries the new hashes, a
note on the Lithuanian entries and the README screenshot; ATTRIBUTION.md is
regenerated.
- README: a screenshot of the Verify screen, taken with
`cargo xtask screenshots` from a synthetic scan (`shot --ocr-verify on`) built
from allowed assets; the page reads it with the real engines.
Tests: pdfcraft-ui-egui lib 373 passed (1 ignored: the Windows hinting
measurement probe), tests ocr 6, control 46, fonts 9; clippy -D warnings clean on
the engine, ui-egui, pdfcraft and xtask packages; `cargo xtask assets` ok. The
review state machine has unit tests for every fix above; each was seen failing
with its fix reverted.
* M10.23: parity entries, roadmap and localization notes for the OCR workflow
Records what M10.20-M10.22 ship, and what they do not.
parity/acrobat-features.toml
- Status changes against main: ocr.rotation-detection and ocr.deskew planned ->
shipped (the opt-in steps of M10.21, with their tests); ocr.correct-recognized-
text and ocr.ocr-engines planned -> partial. Other Area I entries get their
evidence and notes brought up to date.
- ocr.correct-recognized-text: the evidence includes the one-page-at-a-time accept
and the region re-read tests; the notes say what the headless tools cover
(ocr_words with a retained review, ocr_review_apply through the same stale-
document guard, ocr_dictionary) and what is still UI-only (suggestions,
per-word Verified marks, region re-reads).
- ocr.ocr-engines stays partial rather than shipped: part of its evidence is
conditional (the real-binary test runs only where tesseract is installed and
skips elsewhere, and the process-level tests are Unix-only). It cites the tests
that always run (location validation and the fail-closed rule, --list-langs
parsing from stdout or stderr, the merge rules, the default strategy) and says
which part is not proven everywhere.
- `cargo xtask parity`: area I 32.7% -> 44.2% weighted (5 -> 7 shipped, 7 -> 9
partial); overall 52.8% -> 53.0% shipped and 58.2% -> 58.5% weighted.
ROADMAP.md
- One progress-log entry (2026-10-13, newest first) and the banner line. It says
the catalogs are 21 with the Lithuanian additions not natively reviewed, that
the end-to-end redaction test of the Type3 layer needs the craft-fonts build
input, and that recognize_text_makes_a_scanned_page_searchable still fails where
the models are installed, as main's log already records.
docs/localization.md, docs/localization-parity.md
- The Lithuanian entry count (2,578 -> 2,668) and the counts of the other
catalogs that carry entry counts are re-measured with the 90 new entries; the
Lithuanian OCR entries are marked as not natively reviewed.
Checked: `cargo xtask parity` (numbers above, evidence tests exist) and
`cargo xtask assets` pass on this tree.
* M10.24: ocr: apply a late result only to the document it was read from
The Recognize Text dialog closes on Go, so the document can be edited, or have
text redacted, while a long run is still reading. The result was applied
without the stale check the tools and the Verify screen use, so words read
before a redaction could be written back as invisible text. The run now keeps
its guard and applies through the checked path.
Accept with the editable output in the Verify screen had the same gap (Exit
keeps the review open): it now refuses when the document changed since the
review started.
Both new tests fail with their guard switched off.
* M10.25: ocr: ocr_dictionary takes dictionary file names only
Updating sorts, lower-cases and rewrites the file it is given, so pointed at
.env or a README it would corrupt it. The tool now accepts only
ocr-dictionary-<language>.txt style names, for reading as well as writing.
The size-limit test used a file name the rule now refuses first, so it renamed
its fixture to keep testing the size limit. The new test fails with the rule
switched off.
* M10.26: pt-BR: keep (s) on the word counts and say mecanismo for engine
Two review fixes from a native speaker: the two word(s) lines had lost their
(s), so a count of 1 read as 1 palavras, and engine was translated both as
motor and mecanismo. Mecanismo is the Brazilian word for a software engine and
two lines already used it, so the other six now match.
* M10: fit the rebased OCR workflow to current main's structure
* Fix OCR workflow issues from the review
Honor the Recognize dialog's editable-output choice: its result opens in
the review screen (whose Accept writes the editable document) instead of
an invisible layer. Make page acceptance idempotent: a second Accept
entire page never appends the OCR layer twice and keeps later
corrections. Move page and region re-OCR onto a worker thread with a
status line and a cancel that discards the reading. Skip the Tesseract
probe for jobs that name their engines. Bound Tesseract's stderr while
the child runs, not only after it exits. Surface the editable output's
substitution notes in the tools' and the run's results.
Also repair the OCR batch tool against the current structure: inputs are
held to the read root again, and a batch whose inputs share an output
name is refused before the output folder is created, compared the way
the default filesystem compares names; and the editable writer test's
word stays inside the fixture's pages.
* Apply pre-review fixes to the OCR workflow
Hold the automation OCR tools to the document's copying permission, as
the other text tools are: the recognized text is left out of the
results when copying is forbidden, and the paths that carry the words
out of the document (the editable output, the review word list) are
refused. Mark the ocr_dictionary tool as overwriting its path. Close
the searchable layer's graphics state around its invisible text so the
rendering mode cannot leak into later content. Read the OCR user
dictionary folder from the portable data folder in portable mode, like
the recovery store does. Resolve the attribution manifest's leftover
conflict markers and regenerate the generated attribution. Describe the
review flow, the searchable layer's Type3 fonts and the parity evidence
references accurately, and drop an undeclared copy of the recovery
module.
* OCR: reject readings that exceed the word limit
Assisted-by: OpenAI Codex
* OCR: new documents go through the page tree builder main added
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* OCR: review notes and lints
The editable output refuses a file created during recognition. ocr_words takes
skip_text_pages and force_ocr. Automatic OCR checks the engine it will use. The
stderr test stays below the kill cap, and a failed --ocr-verify shot exits with
an error.

* OCR: restore the Verify screenshot attribution, follow the moved constants
The merge dropped the screenshot row with the translation rows. The model
filename constants live in ocrs.rs now, so the license check reads them there.
