Function apply_cache_replay_entry 

pub fn apply_cache_replay_entry(
    cache: &mut Cache,
    entry: &EventStoreEntry,
) -> Result<bool, CacheReplayError>

Applies one event-store entry to cache state when a replay rule exists.

Returns Ok(true) when the entry changed cache state and Ok(false) when the payload is outside the current cache bootstrap replay surface, or when a position event’s target position is absent from the cache (logged as a warning so the report’s ignored count surfaces the divergence instead of claiming a full apply).

Errors

Returns CacheReplayError::Decode when a supported payload cannot be decoded and CacheReplayError::Apply when the decoded payload cannot be applied to the cache.
