Automated README summary
Automatically summarized from the README on 24 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Vite/TypeScript playground testing whether a System One model can steer music across eight styles. Jev (or an offline stub) chooses only enum labels; app code expands them into notes, engraves with VexFlow, plays with smplr, and exports MIDI.
How it uses Jev
Jev makes typed decisions on a style string: globals (register, motion, accompaniment, form, key, meter, palette, tempo, dynamics), phrase (harmony-book phrase per 4-bar slot), and score. Results are closed enums in a CompositionPlan JSON, fed to renderPlan(plan, seed) in MusicApp.tsx.
Primitives:choicescorenoul
Technique worth stealing
Separate the planner from the renderer: Jev emits only closed enums, a pure deterministic renderPlan expands them into notes.
Try it
npm install && npm run dev — works offline with the heuristic stub.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
