This DSLO v0.8 meta-class paper defines the Biological \& Ecological Systems domain cluster, its geometric inheritance, system surfaces, invariant bindings, and metadata heartbeat. It anchors biological and ecological domains into the DSLO v0.8 constellation as a stable semantic object. These systems express DSLO geometry through adaptive morphology, environmental curvature, resource flow, ecological drift, collapse thresholds, recovery windows, identity fields, and legality planes.
