Struct PlanLimits 

pub struct PlanLimits {
    pub key_cache_per_crate: usize,
    pub key_cache_total: usize,
    pub history_per_crate: usize,
}

How many candidates each source may contribute to one plan (kunobi-ninja/kache#616).

These bound plan COMPOSITION, which is a different job from the daemon’s key/byte/time budgets: those bound resource use and are the trust boundary, these stop one low-confidence source from crowding out better candidates before the budget is even reached. 0 disables a cap.

Fields

key_cache_per_crate: usize

Key-cache variants per crate. A crate name is not a build identity, so of n variants at most one can be the right one; taking many is paying n downloads for at most one hit.

key_cache_total: usize

Key-cache candidates across the whole plan, so a build with hundreds of unresolved crates cannot fill the plan with guesses.

history_per_crate: usize

History entries per crate. Unlike shards, where one crate legitimately has several compile units, extra history rows for one crate are older variants.
