Harmonia is an asynchronous content engine for startups. It turns an authorized video or brief into grounded strategy, an editorial plan, reviewed content, approval-bound effects, receipts, and independent verification.

Core promise

Agentic specialists make bounded judgments. Deterministic application code owns workflow state, policy, approval, external effects, idempotency, receipts, and verification. Firestore is durable truth; Memory Bank is advisory context only. Start with the architecture, continue through the pipeline, then use the quickstart and evaluation guide.
