Struct OrphanProvenanceSource 

pub struct OrphanProvenanceSource {
    pub source_id: Option<String>,
    pub rows: u64,
    pub governed_rows: u64,
    pub reserved: bool,
}

0.8.20 Slice 5d (R-20-E8) — one source_id bucket in an OrphanProvenanceReport. source_id is None for the NULL-provenance bucket, which after migration step 21 should contain ONLY governed NODES.

Fields

source_id: Option<String>

None = the NULL-source_id bucket.

rows: u64

Canonical rows (nodes + edges) carrying this provenance.

governed_rows: u64

How many of rows carry a logical_id.

NOT the same thing as “purge-addressable”: only a NODE’s logical_id confers purge-addressability. An EDGE’s logical_id is a supersession identity and reaches no erasure verb (see [Engine::orphan_provenance]), so governed edges are counted here but are NOT subtracted from OrphanProvenanceReport::unerasable_rows.

reserved: bool

True for the engine’s reserved _-prefixed namespace (_engine:*, _legacy:pre-0.8.20). Reserved buckets are reachable only through the operator seam excise_source, never through the governed Engine::erase_source.
