engrave2svg v1.0.2: Graph-Theoretic Analysis and Null-Model Framework for Blombos Engraved Ochre

This archive contains version 1.0.2 of the engrave2svg software framework and associated reproducibility materials used for graph-theoretic analysis of engraved geometric motifs, including the Blombos engraved ochre net-template study.

Contents include:

• SVG graph extraction and topology analysis tools

• Random, lozenge, and bisected-lozenge control generators

• Null-model comparison and significance testing scripts

• Manual SVG traces used in analysis

• Metrics and comparison outputs

• Reproducibility archive accompanying the manuscript

The software converts traced line motifs into graph representations and computes orientation, connectivity, cycle, triangle, four-cycle, lozenge, and bisected-lozenge metrics. Synthetic control networks are generated and compared against observed motifs using empirical null-model testing.

This release corresponds to the analyses reported in the revised Blombos engraved ochre net-template study and is intended to support computational reproducibility and independent verification.
