aiongg 18ae8e4761 Merge upstream main a184db6f8 with our 15 PRs (batch-0) into next
Conflicts resolved per file (both sides kept unless noted):
crates/engine/src/atomic.rs | 1 | main's: `write_file` removed (main routes command writes through `crate::io::write_file`); its one caller in file.rs now uses `crate::io::write_file`
crates/engine/src/cmd/datamerge/fill.rs | 1 | next's `Graphic` literal (has `clip` and `wrap`, which next's `Graphic` carries)
crates/engine/src/cmd/datamerge/mod.rs | 1 | main's `read_path_capped` (crate::io metadata/read_capped, roots checked); next's capped read is the same behaviour
crates/engine/src/cmd/datamerge/parse.rs | 1 | main's (`crate::io::metadata`, `crate::io::Metadata`)
crates/engine/src/cmd/edit.rs | 1 | next's `spread_param(p, "edit.paste")` (the second argument is the command id on both sides)
crates/engine/src/cmd/export.rs | 3 | main's: EPUB params doc, `toc_title` once (main's position; next's duplicate dropped)
crates/engine/src/cmd/file.rs | 7 | place doc: next's (lists page/rect/autoflow params #803 checks); next's recent-file functions + main's `foreign_document`; next's open (load_bytes, warnings, non-DesignCraft refusal) with main's checked `crate::io::read_file` for the bytes; main's `check_write` be
crates/engine/src/cmd/find.rs | 7 | main's Find scope (FindContext, scope/selection/story, continuation, UTF-8 repair) on next's `designcraft_compose::grep::Grep` (dialect GREP): find uses `find_all` capped at MAX_MATCHES, change uses `replacements`/`find_all` (literal change text not expanded), fin
crates/engine/src/cmd/fonts.rs | 1 | next's (`has_style`, resolved/replacement face); `has_style` already compares styles ignoring spacing and case, which is main's `same_style` fix; main's test kept
crates/engine/src/cmd/interchange.rs | 1 | next's `import_idml_report_with_previews` (previews for unreadable links)
crates/engine/src/cmd/layout.rs | 8 | pages.insert: main's overflow-safe `after` + next's checked `parent_ref`; main's duplicateSpread doc; layout.section: next's `SectionEdit` (already keeps unnamed settings, #717) with main's `d.repaginate()` moved into `SectionEdit::apply` (remove and set paths),
crates/engine/src/cmd/links.rs | 5 | next's links.list (no doc clone); main's `text_status` via crate::io; `use std::io::Read` dropped (unused after main's read_capped); test literals main's. `link_missing` (next) uses `crate::io::exists` for the file-guard scan
crates/engine/src/cmd/object.rs | 4 | object.fill/stroke tint-alone: main's (23e1680e7; out-of-range tint is an error, which main's test asserts); object.fit doc: next's (lists `axis`)
crates/engine/src/cmd/paths.rs | 1 | next's (shatai transform on outlines)
crates/engine/src/cmd/place_text.rs | 1 | next's `add_flow_frame` (used by autoflow)
crates/engine/src/cmd/preflight.rs | 2 | next's overset/unplacedStory issue (its `overset_location` already applies the parent transform main's #738 fix adds); next's two test modules kept with main's
crates/engine/src/cmd/scripts.rs | 1 | combined: next's `in_undo_step = false` (#406) + main's full rollback of a failed script (#709)
crates/engine/src/cmd/style.rs | 14 | param docs next's (gradient swatch.create, swatch stops, model colours); create_para next's; rename_style main's structure (rename entry, then `redirect_style_refs`), redirect has next's full reference set (cells, defaults, notes, TOC) + main's never-based-on-it
crates/engine/src/cmd/text.rs | 10 | main's selectSentence/Paragraph/Story + select_around; next's selectionAttrs (mixed) + main's openTypeFeatures/type.feature; main's comments; tracked typing: next's `reserve_command_text` + main's `insert_format_at`; empty-paragraph mark formatting main's (with `
crates/engine/src/cmd/thread.rs | 1 | next's `spread_param(p, "text.thread")`
crates/engine/src/dtd.rs | 1 | next's linear, depth-bounded `expand_parameter_entities` with main's budget (input + 1 MiB, `MAX_EXPANDED_BYTES`) and message ("expand the DTD beyond"); 16 MiB constant removed; both sides' tests pass on message
crates/engine/src/guard.rs | 2 | main's whole-transaction snapshot (docs, active, journal; #742) + next's `in_undo_step` restore; tests both
crates/engine/src/lib.rs | 5 | LoadedGraphic doc next's; next's `new_document_preview`; execute: main's `discard_stale_find_scope()` before next's nested-undo run; modules both (tests_autosize, tests_file_guard, tests_params, tests_roots)
crates/engine/src/recovery.rs | 1 | next's test (superset of main's assertion)
crates/engine/src/tests.rs | 4 | moved tests deduplicated (identical on both sides); next's preflight and direct-selection/kerning tests + main's style-delete, locked-frame and baseline-fit tests
crates/engine/src/tests_idml.rs | 3 | main's order (drop cap and margins tests identical on both sides, once each)
crates/ui-egui/src/canvas.rs | 3 | next's screen_options/DisplayKey block and tests kept; two tests that auto-merge had added twice (parent_guides_on_a_page_are_not_picked_there, baseline_grid_lines_are_the_ones_on_the_page) kept once; main's `typing`/`screen_at`/`click` helpers and its tests clicks
crates/ui-egui/src/control.rs | 3 | main's `count` check and pending budget (control queue + synthetic queue); exact-budget test runs both sides' cases (click 255 on 9,492 pending; drag 9492×255)
crates/ui-egui/src/cursors.rs | 1 | main's (same Pen cursor set)
crates/ui-egui/src/dialogs.rs | 14 | dialog body (newDocument … alert match) is next's text, with main's Find/Change scope reset (`set_field`, `reset_find_scope`, `find_change_params`) and main's Create Guides / Margins and Columns arms ported in; `Dialog::new` ruby section (next) + main's `set_fi
crates/ui-egui/src/i18n.rs | 7 | ka and pl modules, languages, statics and lookups both; `category_first` covers uk, ru, pl, ka and `count_label` keeps next's Czech plurals; shared TABLE union; next's duplicate rows for Auto, Number:, Gutter:, Top:, Bottom:, Inside:, Outside:, Left:, Right: dropped

# File format parity
> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-13 · **Change:** minor (.indd and .indt open through indd-utils; XLSX cached values preserve numeric precision and text; shared print spooler; Windows CI passes; content-indexed asset deduplication, #727) · **Target:** Adobe InDesign 2026 (21.6)
Every format InDesign 2026 reads or writes, with DesignCraft's support, fidelity and tests. The
InDesign list comes from its bundle's `Info.plist` (`CFBundleDocumentTypes`,
`UTExportedTypeDeclarations`), its import/export filter folder names and its File menus; ours from
the open/place/export filters in `apps/designcraft/src/main.rs` and the `file.*` commands.
Overall numbers: [target-app-parity.md](target-app-parity.md); open problems: [gaps.md](gaps.md).
**Dimension score: ~40% ready (estimated), 150–250 h + 10–30 h for an INDD corpus.** The
largest gaps are that neither `.indd` opening nor IDML is measured on real files.
Read/Write: **✓** supported · **~** partial · **✗** missing · **—** InDesign doesn't either.
Weight: what share of an InDesign professional's file traffic the format carries (used for the
score below).
## Documents and interchange

|---|---|---|---|---|---|---|
| InDesign document | `.indd` | read/write (native) | ✓ (converted to IDML in memory by [storytold/indd-utils](https://github.com/storytold/indd-utils), then the IDML importer; #21, #114) | ✗ | Converter warnings join the open result; unreadable files are open errors. Synthetic-bytes tests only; indd-utils reports 96.9% of IDML values reproduced on ~650 pairs. No real-file corpus test | 30% |
| InDesign template | `.indt` | read/write | ✓ (as `.indd`) | ✗ | As `.indd` | 2% |
| InDesign Markup | `.idml` | read/write | ✓ | ✓ | Synthetic fixtures in `crates/idml/src/tests.rs` (51 tests); exported files verified by opening in InDesign 2026 by hand; indd-utils' 98-document run imports 811 spreads / 2,866 stories / 5,812 items. Open: #193, #338, #339, #340, #211. No real-file corpus test | 20% |
| DesignCraft native | `.designcraft` | — | ✓ | ✓ | zip + JSON, versioned; round-trip tests. Asset loading and compaction index by content hash, then confirm byte equality; equal-sized distinct files fall into separate search buckets (#727).

## Score
Weighted by the Weight column (documents, output and placed tables; resources unweighted),
counting ✓ = 1, ~ = 0.5, IDML at 0.6 and INDD at 0 until a real-file corpus measures them:
**~45% present**. Taking fidelity into account (INDD and IDML unmeasured, PDF/X-1a and presets
missing), **~40% ready for real work** (estimated). A measured INDD corpus moves this dimension by
up to 30 points.
## Remaining effort
| Work | Opus 5.5 h |
|---|---|
| INDD real-file corpus, metric, fixes (#21, #114) | 10–30 |
| IDML real-file corpus, metric, fixes (#193, #338, #339, #340) | 60–100 |
| PDF/X-1a and X-3 (transparency flattener), PDF presets and `.joboptions`, external validator | 40–70 |
| Print fidelity, PostScript level 3 output and print presets | 25–45 |
| ICML story import, IDMS snippets | 15–25 |
| HTML / fixed-layout EPUB with live text | 20–35 |
| JPEG export dialog, SVG export, EPS export | 10–20 |
| **Total** | **180–325** (150–250 excluding INDD and PostScript output) |
## Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-13 | minor | Asset loading and compaction use content fingerprints with exact equality checks; tests cover equal-sized distinct buffers, shared copies, independent links and missing data (#727) |
| 2026-10-13 | minor | `.indd` and `.indt` read through storytold/indd-utils; INDD remaining work is a real-file corpus (10–30 h); score unchanged until it is measured |
| 2026-10-12 | minor | XLSX table placement and data merge preserve small numeric values and cached formula strings; synthetic regressions in `textimport::xlsx::tests`. Scores unchanged. |
| 2026-10-10 | major | Created from InDesign 2026's declared document types and filters, `plan/indesign/08-file-formats.md` and the code |
