A line clears a Jump Object wrap with its leading box, [baseline - leading,
baseline]. It stays above the object while its baseline is at or above the
wrap top, so its descenders may hang into the wrap. The next line moves down
by whole leadings from the line above, after any space before or after,
until its leading box clears the wrap bottom. A line that would start a
column under an object starts as if the frame top were the wrap bottom (the
frame's first baseline offset below it). Wrap offsets, negative ones
included, set the wrap's edges.
Other wraps that leave no usable slot, such as a full-width bounding box,
push the line so its top lands exactly on the wrap bottom: the search jumps
from one exclusion bottom edge to the next. Lines aligned to the baseline
grid snap to the next grid line after a push and are re-checked, so they
stay on the grid. The breaker's slot estimate uses the same rules.
expect() calls become let-else / fallbacks. A parent spread without pages
(possible in a .designcraft file) no longer underflows in parent_page_for,
and check() rejects a next_id so large that allocating ids would overflow.
Both crates deny the panicking lints.

- render: damage()/damage_with() — changed items and only the frames whose composition changed
(cache keeps the composition each edit replaced; Cache::composed_for matches a document
version exactly); conservative full repaint for styles, swatches, layers, parents, wrap,
effects and cross-story text (+ tests incl. pixel-identical patch vs full render)
- UI: canvas patches its texture after edits with the view unchanged (0.6 ms vs 22 ms on the
sample when typing); perf harness row for the damage repaint

- doc: OBJECT_MARK with Story::objects (items normalized to the origin) kept in sync on edits,
copy/paste slices and threading
- compose: inline objects are wide glyphs sitting on the baseline (Y offset; auto leading grows);
above-line objects push their line down; placements per frame follow vertical justification
- render + PDF draw anchored items with their lines
- engine: anchored.insert/options/release/list; pasting copied items into text anchors them;
Options/Release act on the object at the insertion point (+ test)
- Object › Anchored Object menu

- doc: INDEX_MARK with Story::index_refs kept in sync (topics 1–4 levels, sort keys, current
page / to end of story / next n paragraphs / suppressed / See / See also); index builder with
section headings, nested or run-in entries, merged page ranges; Document::index for updates
- engine: index.addReference (topic from the selection), index.list, index.generate, index.update
with Index Title / Section Head / Level 1–4 styles (+ tests)
- IDML: PageReference markers and the Index topic tree with See / See also cross-references,
both ways (verified in InDesign 2026)
- Layout › Index menu

- doc: ANCHOR_MARK / XREF_MARK with Story::anchors / xrefs kept in sync on edits, 11 formats
(InDesign's building blocks + partial paragraph), paragraph anchors, typographic quotes
- compose: anchor pages via an XrefIndex (cached per document signature); cross-references are
resolved at composition, so they never go stale; '??' for missing destinations
- PDF: cross-references become link annotations to the destination page
- IDML: export/import as HyperlinkTextDestination / CrossReferenceSource / Hyperlink /
CrossReferenceFormat (+ XRef page variables); verified live in InDesign 2026
- engine: xref.insert/list/setFormat/defineFormat/formats, anchor.create/list (+ tests)
- UI: New Cross-Reference dialog (styles → paragraphs, format); menu pass adding TOC, sections,
text variables, hyperlinks, footnotes, step and repeat, spelling, fitting/content submenus,
effects, Data Merge, Preflight, EPUB; fixed-parameter menu variants; ui.menu.invoke opens
generated dialogs; every-menu-entry-is-a-command test

- doc: FOOTNOTE_REF marker + Story::notes (kept in sync on insert/delete/thread), FootnoteOptions,
NumberStyle::Symbols, footnote text addressed like cell text (CellAddr::footnote)
- compose: notes numbered (continuous / restart per page, spread, section), composed at column
width, body text makes room, stacked at the column bottom with the rule above
- render + PDF draw footnote text; IDML export/import in InDesign's structure (verified in
InDesign 2026), FootnoteOption preferences
- engine: footnote.insert/options/list/setText/delete/goToReference (+ tests)
- UI: caret/selection in footnote text, Footnote Options dialog, Type menu entries; menu items
labelled '…' with parameters open a dialog generated from the command's params doc
- sample magazine carries a footnote

- hyphen: bundled en-US dictionary from the public-domain Moby Hyphenator II
list (Grady Ward, Gutenberg #3204), front-coded + deflated (433 KB), with
case/apostrophe/punctuation/compound handling and inflection inheritance;
our own Liang patterns (19.5k, 129 KB) trained by a patgen-style trainer
(hyphen::patgen, examples/hyphgen.rs) for unknown words; heuristic last.
Discretionary hyphens replace automatic points.
- breaker: prioritised word/letter/glyph-scaling glue in Knuth-Plass and
layout; uncapped badness; hyphen limit as a hard constraint (hyphen-count
states); hyphenation zone for ragged text (both composers); ragged
hyphenation measured correctly; optical margin alignment; balance ragged
lines; Knuth's node pruning.
- compose: Keep Options (keep with next, keep all lines, keep first/last)
via paragraph snapshots; desired spacing applied to all alignments;
justified last lines shrink instead of overflowing; word shaping and
hyphenation caches (300k-char story: ~40 ms warm, ~60 ms cold).
- tests: golden corpus, perf (ignored), keeps, balance, optical, zone,
limit, letter/glyph scaling, discretionary hyphens.
