Struct GraftOverlay 

pub struct GraftOverlay {
    pub effective: Registry,
    pub reports: Vec<RecordReport>,
}

The effective tree record files produced, with their evidence. 记录文件产生的有效树及其证据。

reports is the kernel’s reconciliation evidence for the records that were carried through. It is also printed by apply_recorded_grafts, so a host that never looks at this struct still sees every problem. Records the kernel refuses, and plans this loader cannot parse, never reach here: they are an Err instead of a field. reports 是被带过来的那些记录在内核里的对账证据。它也会由 apply_recorded_grafts 打印，因此从不查看本结构体的宿主依然能看到每一个问题。 内核拒绝的记录与本加载器解析不了的计划到不了这里：它们是 Err，而不是某个字段。

Fields

effective: Registry

The base tree with every applied record overlaid. 叠加全部已应用记录后的有效树。

reports: Vec<RecordReport>

The kernel’s per-record reconciliation evidence, problems included. 内核逐条记录的对账证据，含问题项。
