Function embedding_text 

pub fn embedding_text(memory: &CanonicalMemory) -> String

The text to embed for a record.

The statement, followed by the record’s own frontmatter written as prose. This is the measured-best input to a dense retriever for this corpus — see the module docs for the comparison it won.

Use this in a SemanticFallback implementation so that what is indexed matches what was measured:

for record in records {
    let text = embedding_text(record);
    // embed(&text) and store the vector against record.id
}
