The cross-reference index composed its destination stories through
the cache. One with a running header asked for the running-header
index, which composed the story holding the cross-reference, which
asked for the cross-reference index again: the stack overflowed and
the app aborted. Destination stories with a running header are now
composed without it, like those with cross-references already were.
- 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
