Foundation ready · scaffold

Focus Labs.

Instanced workspaces — one project is a single source of truth, opened through multiple viewpoints.

One truth, many viewpoints

A Lab is an instance: it owns the project — tracks, clips, samples, timing, loop, lyrics — as one live model. Songbook and Booth are views onto it, not separate copies. Edit in one, it's there in the other. Leave a viewpoint and it freezes (loaded, not running); the instance stays warm until you exit the Lab.

Viewpoints

Foundation

Songbook

Writing, arrangement, timeline.

The Booth

Performance & capture — same project, different lens.
window.slpLab · instance store + viewpoint/freeze contract

Scaffold — the data foundation (window.slpLab) is built and dormant; standalone Songbook is untouched. When the Booth is built it attaches here as a second viewpoint on the same instance. Nothing ships to users yet.

Tutorial Manager

Tutorials, from one desk.

Build, edit, and publish the in-app tutorials and walkthroughs — like the Songbook tour — across every surface of StemLabPro.

This is the home for tutorial management. Tell me what staff should be able to do here — author new walkthroughs, edit the existing Songbook tour, choose which tool shows which tutorial — and I'll build it on top of this scaffold.

AI Vision

Checking…

👁 Eyes
Screenshots of the live app (/shot, /views). Purely passive — looking only.
🪟 Own view
Claude flips pages + screenshots its own hidden copy of the app — your screen never moves. Off = it looks through your window (view-switching needs Hands).
✋ Hands
Drive the UI — run JS, click, navigate (/eval). Off = no navigation or clicking; screenshots can't switch views.
🪟 Own view only
Claude may click + type inside its hidden copy while Hands is off — your screen stays untouched. Same account & data, separate window.
👂 Ears
Measure real audio output — fade / loop / timing envelopes (/ears).
🖐 Play control
Claude may press Play/Stop to hear its work — even with Hands off. Off = it only hears what YOU play.
🩺 Health recorder
Logs engine stalls & process crashes to health.log. Kills itself after 30 min.

Lore

Bound in amberglass, the realm keeps its first songs here — every page a room, every room a year. Those who read aloud are said to wake the light.

Serial SLP-001-A7F3 Each card carries a unique code that pairs it to a numbered physical edition.
Physical edition

Format preview — sample art, lore and serial codes shown to demonstrate the card layout. No cards minted yet.

Prestige

Threshold emblems, minted at milestone levels and carried across every app through Legacy. The level never resets — the emblem travels, the level stays.

Placeholder emblems + titles. Final art is crafted intentionally — HTML/SVG for CAA (renders in any client, works offline), with 3D like the Songbook figure as an optional enhancement in desktop clients. The frames below only reserve the slot.
