Simple pricing
Start small. Stabilize continuously.
Harmonic is priced for adoption: lightweight enough for every meaningful model output, with a clean upgrade path into the Solace Governance Pack when runtime risk requires deeper admissibility controls.

The Governance Pack is the bundled upgrade path from lightweight stabilization into runtime governance: Reality Contact + Authority Continuity + Consequence Boundary + Runtime Admissibility.
Enterprise Kernel and Veil Runtime deployments are handled separately for higher-consequence environments.
Governance primitives
Explore the primitive surfaces behind the Governance Pack.
Each primitive governs a different runtime failure topology. Together they extend Harmonic from lightweight stabilization into deeper admissibility control.
