every thread is a kiln cycle
Concurrent execution is not noise. It is many small fires burning calmly and in concert — each one shaping something different from the same patient heat. The engine does not hurry any single thread; it simply refuses to wait in single file.
A ping when a cycle finishes. A slow breath before the next piece enters. And across the workshop floor, dozens of identical patient moments, overlapping, never colliding — because the design of the space itself keeps each piece on its own shelf, its own mutex, its own quiet rotation.
