At most onceA resumed run never re-charges a card or re-sends an email. Side effects are recorded on the journal, not replayed on recovery.
HA in one processThousands of concurrent durable runs survive crashes and node handoffs. No cluster, no separate workflow engine to operate.
Verifiable audit trailEvery run emits RFC 6962 Merkle proofs, checkable offline without trusting the vendor or the process that produced them.
Provably convergent stateShared governed state carries machine-checked convergence, not eventual hope. Coordinate agents on state you can prove settles.
The whole agent surfaceModels (OpenAI, Anthropic, Gemini), tools, typed multi-step flows, memory and RAG, MCP, multi-agent coordination, and typed human-in-the-loop.
A library, not a clusterPlain Go. Import it, bring your own store. Built for ambient agents that run unattended and act under audit.
