Milestone

After a year of working only on foundations – work that must succeed by disappearing – we are finally ready to turn to visible things. Music, for instance.

This Grafana dashboard shows eighteen minutes of a distributed system handling real client connections. The server sits at a 44 MB baseline and stays there: no memory growth, no thread churn, zero old-generation garbage collections. The jump to 83 MB comes not from client load, but from Grafana itself polling for statistics.

Those numbers matter because they validate architectural decisions made months ago. Functional programming principles, STM coordination, gRPC infrastructure: all the invisible work that had to be right before building anything a user might see.

Stable thread pools. Clean memory management. Efficient client handling. Nothing dramatic – just solid enough to carry what comes next.

The system no longer needs proving. Now it needs notes.
