Struct Daemon 

pub struct Daemon {
    pub max_concurrent_runs: usize,
}

How the daemon loop itself behaves, as opposed to what one run does.

Machine-layer material in the same sense Repos::roots is: how many competitions this machine’s own loop is willing to babysit at once is a fact about the machine running magi serve, not about any one repository’s task, so it belongs in <config_dir>/magi/config.toml rather than a repository’s own magi.toml - though, like Repos::roots, nothing stops a repository from setting it too, since a scalar field takes whichever layer has the highest precedence.

Fields

max_concurrent_runs: usize

How many runs magi serve may have actively in flight at once. One by default - today’s behaviour, one run at a time.

This is a different knob from Graph::max_parallel, and the two must not be confused: max_parallel bounds how many agent processes one run starts inside itself (implementers, judges, reviewers - candidates competing on a single task); this field bounds how many runs - whole competitions, each with its own max_parallel budget - the loop drives side by side, possibly across different tasks and different repositories. Raising max_parallel buys a bigger panel for one task; raising this buys more tasks worked at once. A config file that meant one and wrote the other would either starve a competition of judges or leave the rest of the backlog waiting for no reason.

A run parked waiting on the operator’s land-merge approval - see crate::land - does not hold one of these slots while it waits: the whole point of parking there is to let the loop spend the slot on something runnable instead of sitting on a decision only a human can make. So even at the default of 1, an approval that comes back does not queue behind whatever else the loop happens to be running.
