Enum StallReason 

pub enum StallReason {
    ProviderMissing,
    PoolFull,
    ProviderCircuitOpen,
}

Why a dispatch system declined to start work for an agent this tick.

The two cases look identical from the outside - the agent keeps its ReadyToInfer marker either way - but they are opposites in kind, which is what the watchdog acts on.

Variants

ProviderMissing

The stage names a provider that is not in the registry. Nothing the runtime does will change that: no work is in flight to finish, no permit will free up. Only editing the config and restarting the daemon (or dropping in the matching .rhai script) can.

PoolFull

The model’s inference pool is full. This is ordinary backpressure and resolves itself: every permit is held by a job that the job timeout bounds, and releasing one wakes the driver.

ProviderCircuitOpen

Every provider this stage could use has an open circuit: they have each failed enough consecutive times to be taken out of service, and the stage has no candidate left to move to (issue #201).

Unlike PoolFull this will not clear on its own within a tick or two - somebody has to top up an account or fix a key - so the watchdog fails it like ProviderMissing. Unlike ProviderMissing it can recover without a restart, which is what the grace period is for.
