A live becomes one product, live: one chart of a music, naming the products it plays with by their manifest paths. export live asks the depot's pipeline for it and its parts.

Product

live (subject <musicId>/<difficulty>[/<band>], manifest lives/<musicId>_<difficulty>[_<band>].json) starts from the chart Live/MusicScore/<file> and the jacket Image/Jacket/<name>.

File	Contents
live.json	format 1: the chart, the band and where it was taken from, the counts of the converted chart, the music's master rows, the jacket's object id, and parts
chart.json	the chart as shipped, un-gzipped
notes.json, notes.mirror.json	the runtime notes, without and with the MirrorChart option

parts gives the manifest paths of the products a live plays with: the scene, the note highway with the default note skin and effect set, the default sounds and the music. A subject without a band takes the band of the music's first vocal character.

The product layout makes the live of each chart whose key and jacket the selection holds.

export live

• Writes the product layout of the live and its parts (lives/, scenes/, notes/, noteskins/, noteeffects/, sounds/, music/, assets/). It takes the depot options of export assets (--stored-catalog, --workers, --link, --explain, --dry-run).
• --live-option adds the products of other note skins, note effect sets (with their Light variants at quality Low, where the catalog has them) and note sound sets. The products always hold the mirrored notes, the bar line view and the option tables.
• --format is the web format of the BGM (aac by default). live.music takes it as the parameter audio.
• Errors in the master data (no chart of the difficulty, an unknown leader card) are usage errors reported before the catalog index runs. A band whose start timeline or background the catalog lacks is a usage error too.

Shared helpers

The chart reader and the live share the music record (content.live.music_record), the band choice (band_choice) and the chart key. content.livenotes.default_assets gives the default note skin and effect set.

Checks

• Unit tests on synthetic master tables and object tables: subjects, band choice, the live record, the live document, the stage's select/keys/parts/manifest, the assembled product, and the request export live makes.
• For one real chart, the product's chart, notes, mirrored notes and master rows are identical to what the chart reader writes.
