Struct MergePlan 

pub struct MergePlan {
    pub into_id: Uuid,
    pub from_id: Uuid,
    pub rewires: Vec<PlanPredicate>,
    pub lifecycle: Vec<PlanStatement>,
}

Write plan for a merge op (deduplicate two entities). Rewires and lifecycle writes are split into separate fields precisely so a guard is never ambiguous between them: the edge rewire is predicate-based (ADR-099 D1 rule 1) and may touch zero or many rows depending on earlier in-file writes, so it is never guarded; the from/into entity lifecycle write assumes both rows exist, so it always is.

Fields

into_id: Uuid

from_id: Uuid

rewires: Vec<PlanPredicate>

Predicate-based edge-rewire statement(s) (UPDATE graph_edges SET source_id = :into WHERE source_id = :from- shaped), evaluated inside the transaction so they structurally see any earlier op’s edge writes in the same file (ADR-099 acceptance criteria: “merge rewires see earlier in-file writes”). Never guarded — a rewire touching zero rows is a legitimate outcome.

lifecycle: Vec<PlanStatement>

The from entity’s soft-delete/tombstone DML (and any other lifecycle write prepare assumed a target row exists for). Always guarded — prepare validated into/from both exist.
