Struct SlotView 

pub struct SlotView {
    pub filled: bool,
    pub ref_count: usize,
    pub last_used: u64,
}

Task #27: a per-slot snapshot for the pure victim-selection policy. Taken on the model thread at a scheduler-quiescent point (the only place ref_count is authoritative), then handed to select_victim_slot.

Fields

filled: bool

true if this slot currently holds a (non-placeholder) adapter.

ref_count: usize

In-flight sequence count (0 == idle == evictable).

last_used: u64

LRU tick (larger = more recently used).
