Queue

Everything the checkers do goes through one queue, and this is it. Nothing here is a simulation — these are the jobs on the box right now.

Running

Idle. A job submitted now starts immediately.

Waiting — 0 priority, 0 free

Nothing waiting.

The fast lane, and what it is not

One Lean job runs at a time — Mathlib is memory-hungry and this box is shared — so when several people submit at once, there is a line.

Any account holding prepaid credit is served first. That is the whole mechanism; there is no separate product to buy. A free run is never blocked, throttled or degraded by it — only overtaken — and it still runs, in order, in the free lane.

The reason it works this way: the people funding the machine are paying for the checks everyone else gets for nothing. Skipping the line is the only thing that buys, and it buys nothing else.
