The refusal guard asked whether any item still had the layer fields, while the export walks
also require a graphic whose asset is a PDF. Relinking a placed PDF to an image keeps those
fields on the item (links.relink replaces the asset in place), so a stale field blocked IDML
and PDF/A-2b exports that used to work. The guard, and the package report, now ask the same
question the walks ask: has_applicable_pdf_layer_overrides requires the PDF asset too, so a
stale choice is simply ignored and the tripwire still fires if a future construct ever puts a
real choice where the walk cannot reach it.
Regression: a_stale_choice_on_a_relinked_image_does_not_block_exports places a layered PDF,
hides a layer, relinks that asset to a PNG and exports IDML, PDF/A-2b and plain PDF - all
succeed, and the document reports the stale field while the applicable helper does not.
Kept separate from the parent-page fix and from the all-on export fix: this is the traversal
remediation on its own.
The detection helpers already walked parent spreads, groups and the stories in table cells,
notes and endnotes, while the two exports walked document spreads only, and the write side
(Document::update_items) did not reach placements nested in those stories either. So a choice
on a frame anchored in a cell's text or in a footnote asked for the newer file format and was
named by the package report, yet the IDML copy carried the file's defaults. The walk was
narrow on main as well (see the probe evidence), so this is pre-existing for the older
hidden-list state; it becomes a wrong claim only because the paired PR added the variants and
said every placement counts.
Document::placed_items recurses those stories (depth budget 64, like the detection side) and
a new Document::update_placed_items applies the change where the placement actually is,
copying only the branches holding a match. update_items is untouched, so unrelated commands
keep their reach. Both exports also refuse rather than fall back when a document has a choice
but the walk found no placement to carry it.
Regression: nested_placements_keep_their_layer_choices_in_saves_and_exports runs a placement
anchored in a table cell's text, then in a footnote: the save keeps the choice, the embedded
IDML copy shows every layer, external-only IDML is rejected, PDF/A-2b export succeeds.
An explicit all-on choice is Some(&[]) for the placed PDF, not the file's defaults, so the
item walk now passes it whenever the placement has a layer choice. Without that, a sheet
that inherits a placed PDF with "show every layer" exported the source's default-hidden
layers instead.
The second half is the fail-closed rule: prepare() skipped writing a group's state when a
visible, named layer needed no change, so an all-on choice on a file whose defaults already
show everything embedded the untouched source - no rewrite, so no error. It now writes every
group's state when a choice is explicit, which is the same catalog rewrite the canvas does,
so a history that cannot take one is reported instead of being embedded.
Regression: the two existing engine tests that were failing (placed_pdf_all_on_is_distinct
_from_defaults_and_survives_exports renders the exported page; explicit_all_on_validates_an
_actual_rewrite_before_editing expects the error for a 33-section xref history).
Gap 19 now states in one sentence that DesignCraft does not apply retained IDML
graphic-layer visibility to raster or PDF output, so it no longer reads as contradicting
placed-PDF layer choices, which are applied. The placed-PDF doc records that parent-page
and anchored placements get variants, and what a package's IDML copy cannot carry.
A package's IDML copy links the placed files, so a per-placement Object Layer Options
choice cannot travel in it, while the packaged DesignCraft document keeps the choice. The
report now says so instead of leaving the two copies to differ silently.
The graphic-layer test covered a mixed document. A save whose only layer settings sit in a
table cell has to choose version 4 too, asserted against the saved metadata.
A dialog opened without the menu's fields has no useDefaults field, and confirming it with
no layer unticked sent useDefaults:false with an empty hidden list: an explicit all-on
choice, which turns a PDF's default-hidden layer on and makes a PDF/A-2b export rasterise
the placement. An absent field now resets to the file's defaults when nothing is unticked,
and only an explicit false means all-on.
The IDML layer-variant pass and the PDF/A-2b rasterisation pass both walked only
document-spread items, so a choice on a parent-page placement (or an anchored one) was
replaced by the file's defaults on export, and an external-only IDML export succeeded
when it could not carry the choice. Both now cover every placement through
Document::placed_items, and the choice is cleared where the placement actually is.
Regression: a parent-page placement with an explicit all-on choice keeps all layers in
embedded IDML, external-only IDML rejects it, and PDF/A-2b rasterises it.
Graphic gained an optional layer_options field, so the test-only literals in the PDF
crate and in the engine's optional-content support need it. No behaviour changes.
Preserve contributor commits and integrate current main. Plain/PDF-X4 exports retain placed PDF optional-content defaults and hidden-name choices; prepared variants are cached, trailer history is parsed structurally, null OCProperties is treated as absent, and unreadable non-null Prev refuses safely. Preserve the recent form/table exporter refactors.
Verified exact integration tree with all nine cargo xtask ci gates (3,209 tests passed, 6 skipped; 16 WASM-safe crates), 118 original-head PDF tests, independent flat/null and Prev export matrices, and 12 qpdf checks. GitHub CI passed; fresh CodeRabbit review covers the exact head with no new actionable comments. Sonar workflow succeeded but its scan was skipped because the fork lacks SONAR_TOKEN.
This landing does not include or release the format-v4 pair #1647/#1671, held separately pending parent-placement IDML layer-choice preservation.
Preserve contributor commits and adapt optional-content registration and table-cell graphic calls to the current PDF exporter refactors. Keep current-main roadmap corrections.
All nine cargo xtask ci gates passed on tree d0c21f347e: 3209 tests passed, 6 skipped, 16 WASM-safe crates. The exact PR head also passed 118 PDF unit/integration tests. Independent production-export controls: 8 flat/null cases succeeded; 7 unreadable Prev values refused, 4 compatibility controls succeeded; all 12 emitted PDFs pass qpdf.
This PR is independent of the format-v4 pair (#1647/#1671), which remains held for a reproduced parent-placement IDML issue.
layout_line set a line with a tab or a right indent tab without the optical
margin or CJK edge hangs, while the greedy breaker and the paragraph composer
counted them. A line that fit only because its period hangs was then squeezed
into the measure or set past it.
layout_line now hangs the edge glyphs of every line. Tabs are measured from the
hung start, so tab stops stay where they are, and a right indent tab fills to
the hung end. A tab at a line edge hangs nothing. Lines without tabs lay out as
before.
* Type: story Optical Margin Alignment with a size, and Ignore Optical Margin (engine, IDML)
A story's Optical Margin Alignment applies to every paragraph except those
with Ignore Optical Margin; hang amounts scale with the story's size.
story.options sets it, type.para and paragraph styles take
ignoreOpticalMargin. IDML imports and exports StoryPreference
OpticalMarginAlignment/OpticalMarginSize and IgnoreEdgeAlignment. The
per-paragraph opticalMargin switch keeps hanging at the text's own size.
Part of #947.
* Type: the Story panel, and Ignore Optical Margin in the Paragraph panel menu and Paragraph Style Options
Window > Type & Tables > Story sets Optical Margin Alignment and its size
for the stories of the text selection or the selected text frames through
story.options, and is disabled without either. type.selectionAttrs
reports the stories' values as storyOptions, null where they differ.
The Paragraph panel menu toggles ignoreOpticalMargin, and Paragraph Style
Options > Indents and Spacing has an Ignore Optical Margin checkbox.
Part of #947.
* ROADMAP: the story Optical Margin Alignment entry names its default and scope
The new commands note.previous and note.next move the insertion point
to the previous or next editorial note in its story and put the caret
after the note's anchor. Previous Note skips the note whose anchor the
caret directly follows, so repeated use reaches every note. Each item
is unavailable when no note lies in its direction in the story, or when
the insertion point is in a table cell or a footnote. The items follow
the Notes panel item in Type › Notes, with translations in the catalogs
that already translate Next Document and Previous Document.
skylartaylor's review: a PDF can list readable layers yet fail the visibility
rewrite. On a synthetic 33-section xref history, object.layerOptions with
useDefaults:false and an empty hidden list was accepted (only hidden names
triggered #1670's rewrite check), the canvas could not draw the choice and
PDF export then failed.
Every explicit choice now runs one actual pdf_hide_layers rewrite per
distinct source before any item is edited or undo is recorded; this subsumes
the separate layerless check. Resetting to file defaults (useDefaults:true
or the legacy empty list) needs no variant and bypasses the check. #1670's
fail-closed canvas handling is kept alongside the explicit-override state: a
stored explicit choice (including all-on) whose source can no longer be
rewritten draws nothing rather than the unmodified source, and export errors.
The new regression test fails before this change (the all-on request is
accepted) and covers both selection orders, atomicity, undo depth, reset
bypass and the stale all-on fail-closed path.

skylartaylor review of #1647/#1671: both PRs introduced native format 4 for
different capabilities. Stacked on #1647, version 4 is one capability:
required_version (the single place that picks a version) asks for it when a
document has retained placed-graphic layer options or an explicit all-on PDF
layer choice, so a version 4 reader understands both. That merge was made
while rebasing "PDF: distinguish all-on layer choices from file defaults",
which also replaced its Document::all_items scan (document spreads only)
with Document::has_explicit_all_on_pdf_layers, covering parent spreads,
groups, anchored objects and nested story content; an all-on PDF on a parent
page previously saved as version 2.
This save/reopen test holds both features in one document, checks each
alone still needs 4, that documents with neither keep 3 (EPS) or 2, and that
a parent-spread all-on choice needs 4.

* Anchored text frames compose against the grid and page where they are placed
An anchored text frame is not a spread item, so frame_specs composed it at
its stored transform: no page, no page side, no page rect, and a baseline
grid phase taken from that transform. A note set to Only Align First Line
to Grid snapped to the wrong line, and page-number markers and
spine-relative alignment inside it saw no page.
The composer now looks up the host story's composition first, finds where
it placed the frame (in its frames' anchored objects, footnotes or table
cells) and composes the frame's story against that placement
(ComposeOptions::placed). The cache does the same and adds the placement
to the entry's signature, so a note recomposes when its host moves it.
Host lookups stop after eight levels, which bounds stories anchored in
each other.
* Anchored text frames: the cache keys on the placed spread's pages
skylartaylor's review: #1647 and #1671 each introduced native format 4 for a
different capability, so a reader that understood only one could accept a
file carrying the other and silently drop its settings. No release has shipped
v4 (main and v0.12.0 still write at most 3), so v4 is defined as one
capability covering both retained placed-graphic layer options and explicit
all-on PDF layer choices; #1671 is stacked on this branch.
Move the version choice into required_version so every new capability is
decided in one place, document the shared v4 contract on VERSION, and test
that plain, EPS-only and layer-option documents keep 2, 3 and 4 respectively.
