Struct CompactionPlan 

pub struct CompactionPlan {
    pub checkpoint: Checkpoint,
    pub retained_ops: Vec<OpRecord>,
    pub dropped_ops: usize,
    pub frontier: Hlc,
    pub as_of_ms: u64,
    pub retention: RetentionReport,
}

A computed (not yet executed) compaction: the retained checkpoint, the ops that stay in the journal, and what happened.

Fields

checkpoint: Checkpoint

The checkpoint to persist BEFORE truncating — frontier heads + retention-applied state, content-addressed over the whole record.

retained_ops: Vec<OpRecord>

Ops strictly above the stable frontier — the journal’s new content.

dropped_ops: usize

How many ops fall at/below the frontier (dropped from the journal, covered by the checkpoint).

frontier: Hlc

The stable frontier the plan cut at.

as_of_ms: u64

The effective reference instant the age rules ran with (the caller’s explicit value, or as_of_from_ops over the below-frontier ops).

retention: RetentionReport

What retention trimmed inside the checkpoint state.
