Struct Lineage 

pub struct Lineage {
    pub job_id: String,
    pub spec_name: String,
    pub spec_fingerprint: String,
    pub model: String,
    pub embedding_model: Option<String>,
    pub cuttlefish_version: String,
}

Lineage carried by every bronze and silver row.

Job-level rather than row-level values are still written per row — see the module docs on why the duplication is deliberate.

Fields

job_id: String

The job directory’s name, which is the job id.

spec_name: String

The spec this job ran.

spec_fingerprint: String

The graph fingerprint the ledger recorded, which pins which pipeline produced these rows. Two runs of “the same” spec with an edited block have different fingerprints, and that difference is the whole reason somebody re-reads their warehouse six months later.

model: String

The chat model, as resolved.

embedding_model: Option<String>

The embedding model, when the spec declared one.

cuttlefish_version: String

The cuttlefish that wrote this. A column, not just a manifest field, because the row format is this version’s and a reader deserves to know which version’s rules it is reading under.

Trait Implementations
