Struct PolicyInput 

pub struct PolicyInput {
    pub effective_target_bytes: u64,
    pub rss_bytes: u64,
    pub caches: Vec<CacheView>,
    pub previous_cache_bytes: u64,
    pub previous_cache_count: u32,
    pub previous_rss_bytes: u64,
}

Inputs the policy needs to compute a new set of caps.

Fields

effective_target_bytes: u64

Effective target after lease deductions, in bytes.

rss_bytes: u64

Most recent RSS reading.

caches: Vec<CacheView>

View of every registered cache, in registration order.

previous_cache_bytes: u64

Sum of cache current_bytes at the previous tick, or 0 if this is the first tick (no history yet). The shrink branch uses this to detect “RSS climbed but caches didn’t” — a signal that the growth came from outside the cache subsystem.

previous_cache_count: u32

Number of registered caches at the previous tick. 0 on first tick.

previous_rss_bytes: u64

RSS reading at the previous tick. 0 on first tick. The flat-caches guard requires RSS to have actually grown (rss_bytes > previous_rss_bytes) so a lease-induced effective-target drop — which raises the rss/target ratio without an actual RSS climb — still triggers shrink.
