Struct CompactionRoutePolicy 

pub struct CompactionRoutePolicy {
    pub threshold_ratio: f64,
    pub retain_ratio: f64,
    pub max_overflow_retries: u32,
}

Per-route compaction policy in the DeepSeek-harness shape.

threshold_ratio caps the auto-compaction trigger as a fraction of the route window (fail-safe: it can only fire earlier). retain_ratio sizes the verbatim continuity tail as a fraction of the route window so small windows keep a usable summary instead of a tail-only history. max_overflow_retries bounds extra bounded-fork attempts after a context-capacity rejection.

Fields

threshold_ratio: f64

Trigger ceiling as a fraction of the route window. 1.0 preserves the absolute-tokens trigger unchanged.

retain_ratio: f64

Verbatim-tail share of the route window.

max_overflow_retries: u32

Extra attempts after a context-capacity rejection (progressive halving).

Implementations

impl CompactionRoutePolicy

pub fn resolve(provider_name: &str, model: &str) -> Self

Resolve the policy for a provider/model route (first table hit wins, otherwise the default).

pub fn tail_target_tokens(&self, window_tokens: usize) -> usize

Verbatim-tail budget for a route window. Unknown windows (0) keep the legacy constant; otherwise the tail scales with the window so small routes keep a usable summary instead of a tail-only history.

pub fn apply_threshold_cap( &self, threshold_tokens: usize, window_tokens: usize, ) -> usize

Fail-safe trigger cap: only fires compaction earlier, never later. A 1.0 ratio (the default) leaves the absolute-tokens trigger unchanged.
