 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.
