Obelisk says SQLite powers durable workflows

This is less a claim that SQLite universally wins than a case for avoiding unnecessary infrastructure on day one. It fits bursty, single-tenant, or small-fleet workloads where operational simplicity matters more than perfect high availability. Litestream is the key tradeoff: it makes SQLite backup-friendly and portable, but asynchronous replication is not a substitute for a strongly consistent shared database. The Postgres comparison is sensible, and the small self-contained state model maps well to agentic systems.
