Struct EscalationThresholds 

pub struct EscalationThresholds {
    pub reject_low_priority: f64,
    pub evict_caches: f64,
    pub spill_operators: f64,
    pub throttle_maintenance: f64,
    pub hysteresis: f64,
}

The pressure thresholds at which each escalation level activates, plus the hysteresis band that keeps the level from flapping around a boundary.

Fractions of the configured maximum, in (0, 1], strictly increasing in the S1E-003 escalation order.

Fields

reject_low_priority: f64

Step 1: reject new low-priority work.

evict_caches: f64

Step 2: evict reclaimable caches.

spill_operators: f64

Step 3: spill eligible query operators (S1E-004 hook point).

throttle_maintenance: f64

Step 4: throttle maintenance.

hysteresis: f64

De-escalation band: a level drops only once pressure falls below its activation threshold minus this hysteresis.
