Local project case

Carry the whole board

Create one integrity-checked .syncstone file with every bank, cue setting, and referenced audio file. Nothing is uploaded; the file stays on this device until you save or share it.

Restore backup

Ready to inspect this local project.

A backup never includes the pair code or a published Live lease. Restoring returns Sync Stone to Standby and requires Publish. Same-browser pairing remains local; this file is not remote sync.

Build boundary

What this release proves

This static feasibility build validates local browser audio, immutable board snapshots, same-origin controller/Player messaging, scheduled acknowledgements, and honest destination readiness.

Works now: Upload short audio, edit pads, publish, arm a Player tab, enter Live, trigger and stop cues.
Local only: Both windows must share one origin and browser profile. Audio never leaves the device.
Local-only contract: No accounts, cross-device networking, cloud media, server rendering, or unattended playback. Any future networked edition requires a separate product and security decision.
Production target: 100+ imports: The planned ingest contract covers 50 fixture candidates plus 200+ best-effort aliases. This static build accepts only audio the active browser really decodes.
