Struct SubjectImpact 

pub struct SubjectImpact {
    pub producer: String,
    pub path: String,
    pub class: String,
    pub selector: String,
    pub consumers: ConsumersReport,
    pub coverage: Option<Vec<CoverageRow>>,
    pub declared_publishers: Option<usize>,
    pub declared_queryables: Option<usize>,
    pub deprecated: Option<DeprecationFact>,
}

The blast radius of one declared subject (#224): its consumers, its storage coverage, what else declares on it, and its ledger entry.

Not ImpactReport — that name is the zenwatch attribution’s (RFC 06 §5.6), a different question about a different plane.

Fields

producer: String

path: String

The subject path as the registry spells it (disk/{mount}/used).

class: String

The declared class chunk; * when the path is known only from the [[deprecated]] ledger, whose entries carry no class.

selector: String

The wire selector the subject’s family resolves to under the base.

consumers: ConsumersReport

coverage: Option<Vec<CoverageRow>>

The RFC 04 §2 coverage rows for this subject. None = the storage sweep was not made (no admin space answered, so an empty list would read as “uncovered”); Some([]) = asked, and the subject is not a state family — coverage does not apply.

declared_publishers: Option<usize>

Distinct sessions declaring a publisher intersecting the selector. Absent when no admin space answered (not asked, O4).

declared_queryables: Option<usize>

Distinct sessions declaring a queryable intersecting the selector.

deprecated: Option<DeprecationFact>

The subject’s [[deprecated]] entry, when the ledger carries one.
