Appendix: Comparative Tool Matrix

Symbol key (applies to all cells): Y = full native support · ~ = partial or plugin-based · N = absent. See the comparative feature matrix in the Results section for a colour-coded heatmap rendering of this table.

¹ Nextflow lineage records operate at workflow scope rather than as a rendered-document citation graph. ² DVC provides content-addressed versioning for data artifacts via its object store. ³ DVC integrates with remote storage (S3, GCS, Azure) but does not natively orchestrate distributed compute. This matrix is a versioned manuscript snapshot, not a continuously updated product survey. A future refresh should re-check every external capability against current primary documentation before changing a cell.
