Reading the Lineage Primitive — cxcscmu Auto-Research, Studied from release_artifacts

cxcscmu's own lineage_on vs lineage_off ablation closes the case: same agent, same trial budget, same prompt template — only the rendered lineage block differs, and the run with lineage produces 5.3× more keeps and 3.2× less wall-time waste. This piece extracts that primitive into fieldkit.lineage.
