See [Score Generation](TECHNICAL_GUIDE.md#score-generation) for supported MusicXML notation, Vamp properties, schema details, and diagnostics. There is no compact-JSON source format or legacy runtime adapter. Unsupported notation fails generation before existing assets are replaced.
|

|
||||
Build-time engraving uses pinned MuseScore Studio 4.7.4 and the OTF Petaluma fonts in `package/assets/fonts/petaluma`. The managed Docker image and CI install the checksum-verified engraver automatically. For a direct host build, run `python3 tools/install_engraver.py build/build_common/musescore` and set `VAMP_MUSESCORE` to the printed executable path. Unsupported or unfaithfully exported notation fails the build rather than being approximated.
|
||||
Build-time engraving is implemented in Python in `generator/engraving`, using the bundled Petaluma OTF fonts and SMuFL metadata. MuseScore is an optional authoring tool, not a build dependency or rendering backend. The managed image and CI install the pinned Python requirements automatically; direct host builds use `pip install -r tools/requirements.txt`. Exact musical timing is retained through layout, and dense measures can continue across systems without shrinking the notation. Missing glyphs, unrepresentable page geometry, and failed notation audits stop generation before replacing existing assets.
|
||||
|
||||
Petaluma is from Steinberg under the SIL Open Font License. Runtime packages include PNG score pages, `PetalumaScript.otf` for UI text, and `OFL.txt`; the music font and engraver stay build-only.

### Engraving Boundary
|
||||
|
||||
`generator/musicxml_writer.py` emits MusicXML from the transformed model. `generator/engraving/` runs pinned MuseScore Studio 4.7.4 with the checked-in Petaluma house style, isolated home/config/font caches, and the repository OTF fonts. The checksum-verified AppImage is installed only on the build host; it is never packaged for the Pi.
|
||||
`generator/engraving/` is a custom Python engraver, not a wrapper around MuseScore or another notation engine. `layout_score(document, style, fonts)` produces immutable layout pages with exact source intervals, notation anchors and drawing primitives. `rasterize_page(page, fonts)` draws one page at four-times resolution and downsamples it. `engrave_tree(root, fonts)` retains the asset-pipeline entry point. `generator/musicxml_writer.py` remains a round-trip/export utility and is not involved in engraving.
|
||||
|
||||
Model support is deliberately broader than engine qualification. More than four source voice identities, maxima, more than four dots, independently sustained tones within one chord, cross-bar tuplets, double stems, custom accidental glyphs, and unqualified microtonal alterations produce explicit engraving errors. Unequal chord durations can be authored as separate voices for this engine. No model limitation or silent approximation is introduced to conceal these failures.
|
||||
`notation.py` interprets staff state, exact pitch positions and shared accidental state; `notes.py` and `attributes.py` construct symbols; `spans.py` handles beams, ties, tuplets, octave shifts and lyric continuations; `layout.py` handles spacing and pagination. `fonts.py` reads bundled OTF outlines and SMuFL metadata, caching metrics and outlines for one generation run. `raster.py` uses FontTools, aggdraw and Pillow only as low-level font and drawing libraries. All dependencies are pinned in `tools/requirements.txt` and remain build-only. Standard glyph names and their upstream notice are vendored alongside the fonts; no system music fonts are consulted.
|
||||
|
||||
Each export is read back as MusicXML and audited for pitch spelling, exact timing, voice/event counts, written values, ties, explicit beams/stems, lyrics, harmony degrees, staff changes, tempos, and spans. Engraver changes fail generation. This is not a claim that MuseScore can engrave every MusicXML construct. Newly supported constructs must pass importer/writer tests, engine auditing, and visual qualification.
|
||||
The former backend-specific four-voice, duration, unequal-tone and tuplet restrictions are removed. Voices retain separate stems and collision offsets; chord tones retain their own written durations and per-tone ties. Pitched, percussion and explicitly fingered TAB material use their own staff positions. Unknown exact microtonal alterations use a numeric rational semitone annotation relative to the natural pitch, not a rounded accidental. An explicit unavailable SMuFL glyph is an error. The single-part/single-staff importer contract and exclusions for dynamics, accents, expressive ornaments and navigation remain unchanged.
|
||||
|
||||
Pages are 976x484 pixels with 12-pixel staff spacing. Pagination is done by the engraver, not by shrinking the page or clipping notation. Blank pages, incorrect dimensions, and ink reaching the page edge are rejected. Runtime letterboxing preserves aspect ratio. Luma's `load_texture_uncached()` lets Product Vamp retain at most two textures without a hidden strong asset-cache reference. The UI reports missing/corrupt assets instead of falling back to the removed renderer. Runtime validates bundle metadata, paths, dimensions, and page checksums; the build validates musical semantics.
|
||||
`audit.py` checks the final layout against the musical model: timeline and fragment coverage, exact fragment durations, actual glyph bounds, pitch positions, visible note primitives, required accidentals, ties, lyrics, harmonies, tempos and spans. It rejects out-of-page geometry and collisions among unrelated noteheads, accidentals and same-lane text. Staff, ledger, stem, beam and tie contacts are intentional. This is not a proof of publication-quality engraving for every possible MusicXML document; notation changes need targeted semantic, geometry and reviewed image tests. The writer's XML round-trip audit is retained separately in the test suite.
|
||||
|
||||
Bundles keep schema version 3 and an unchanged `music` object. Presentation identifies `Vamp Python` version `1.0.0`; its style fingerprint includes the style settings, both font files, font-specific metadata and the glyph-name mapping. Runtime remains engine-agnostic, so valid existing schema-v3 bundles need no database migration.
|
||||
|
||||
Pages are 976x484 pixels with 12-pixel staff spacing, 28-pixel horizontal margins and 18-pixel vertical margins. Dense measures continue across systems/pages; sustained notes become exact, tied presentation fragments and rests become exact rest fragments. These fragments never change the semantic JSON. Irreducible simultaneous content that cannot fit a fixed page fails contextually rather than being clipped or shrunk. Blank pages, incorrect dimensions, and ink reaching the page edge are rejected. Runtime letterboxing preserves aspect ratio. Luma's `load_texture_uncached()` lets Product Vamp retain at most two textures without a hidden strong asset-cache reference. The UI reports missing/corrupt assets instead of falling back to the removed renderer. Runtime validates bundle metadata, paths, dimensions, and page checksums; the build validates musical semantics.
