VGSM Successor Architect

Phase 2

Core Data Contract

This build defines the project model before any music generation work begins. The data shape now has a versioned project root, metadata, cue shells, section event arrays, track and instrument registries, quality reports, and defect reports.

Roadmap guardrail: Project data is authored first; generation, mutation, playback, persistence, and exports beyond JSON stay locked.

Roadmap Notes

Phase 2 Deliverables

Contract Accordion

Project root

schemaVersion, id, metadata, cues, tracks, instruments, qualityReports, and defectReports are top-level contract fields.

Cue and section shells

The blank project includes an empty cue shell and section shell with section.events[] ready for later authored events.

Import/export boundary

JSON import/export is present for contract verification only. Persistent save slots begin in Phase 3.

Fullscreen behavior

The page keeps the viewport-upgraded shell: rails and accordions expand with the browser and scroll inside the available screen.

Non-Negotiables Active

Fresh architecture only.
No hidden export-time rewrites.
UI does not equal phase completion.
JSON data is the source of truth.

Next Phase

Phase 3: Persistence + Recovery.

Local save slots, schema migration, corrupted project warning, recovery snapshot, and Build State panel expansion stay out of Phase 2.
