Architecture and Guarantees

scorekit is a thin compiler and orchestration layer.

YAML scene
  -> semantic validation
  -> Score IR
  -> deterministic MIDI
  -> external renderer
  -> PCM audio
  -> external FFmpeg export

Guarantees

  • The same DSL and compiler inputs produce byte-identical MIDI.
  • Loop and stem lengths are derived from quantized musical time.
  • File-writing commands stage output and publish it atomically.
  • JSON Schema and structured errors expose the same contract used by the CLI.
  • Renderer, orchestration, and texture-source profiles are external data, so scenes remain portable: an orchestration profile routes each track’s logical palette to an independently certified renderer profile, never the reverse.

Deliberate boundaries

scorekit does not implement synthesis, reverb, compression, a DAW, version control, or embedded compositional intelligence. It also does not require fields that only a commercial sound source can satisfy.

The upstream Agent owns narrative and creative decisions. scorekit owns deterministic compilation, validation, orchestration, and artifact integrity.
