Struct Phase3Result 

pub struct Phase3Result {
    pub per_file_edges: Vec<Vec<PendingEdge>>,
    pub per_file_node_ids: Vec<Vec<NodeId>>,

}

Phase 3 result: per-file edges, per-file node IDs, and total written counts for validation.

Fields

per_file_edges: Vec<Vec<PendingEdge>>

Per-file edge collections for Phase 4 bulk insert.

per_file_node_ids: Vec<Vec<NodeId>>

Per-file node IDs actually committed. Indexed identically to per_file_edges — element i is the Vec of NodeIds committed for plan.file_plans[i]. Empty Vec when that file wrote no nodes (slot overflow skip, or a staging graph with only strings).

Used by the caller to populate crate::graph::unified::storage::registry::FileRegistry::record_node, which feeds the Gate 0c bucket-bijection debug invariant.

total_nodes_written: usize

Total nodes actually written (for validation against planned totals).

total_strings_written: usize

Total strings actually written (for validation against planned totals).

total_edges_collected: usize

Total edges collected across all files.

c_indirect_drain: Option<PhaseCIndirectDrain>

Per-chunk drained C indirect-call staging payloads (DESIGN §8.2).

Populated when any file in the chunk staged a super::staging::CIndirectStagingPayload (C plugin Phase 1, U10). None for chunks containing no C files, keeping the wire-shape budget unchanged for non-C workspaces.

Consumed by [apply_c_indirect_drain] from entrypoint.rs after Phase 4c-prime cross-file unification rebuilds the qualified-name index — see U11 plumbing for the full Phase 3 → Phase 4 hand-off.
