Struct LifecycleTracker 

pub struct LifecycleTracker { /* private fields */ }

engine 私有、有限容量的父 Tick 关联表。

关联表只保存 correlation/timer 的标量和 bounded carrier，过载时淘汰最旧项； 它不是 active carrier，也不承担业务正确性。

Implementations

impl LifecycleTracker

pub fn next_tick_id(&self) -> u64

分配下一个独立 Tick ID，0 保留给 engine start 的 synthetic root。

pub fn parent_for_tick( &self, tick: &Tick, ) -> (Option<u64>, Option<TraceCarrier>, Option<TraceCarrier>)

解析 Tick 的上游父关联，并在终态 Tick 到达后释放一次性链接。

pub fn remember_effect(&self, effect: &OwnedEffect, context: &LifecycleContext)

记录效果产生的未来 Tick 关联；超出容量时淘汰最旧诊断链接。
