The DSLO v0.8 Registry defines the classification map for geometry primitives, manifolds, operators, runtime geometries, legality planes, prefix families, and lineage anchors. It provides the structural backbone for the DSLO v0.8 constellation and ensures continuity with DSLO v0.7 substrate‑skin artifacts. This registry anchors the DSLO semantic substrate into a stable, ingestible, and non‑drifting DOI artifact.
