Verify whether the versioned graph reproduces narrative power decline

Determine whether the versioned spatio-temporal graph of NS-ST-GraphRAG reproduces the known decline in Wang Xifeng’s power around the Grand View Garden investigation, as measured through changes in degree centrality, betweenness centrality, and spatial activity across the corresponding narrative-time slices.

Background

The paper proposes H4 as a validity test for the temporal graph: quantitative network measurements should reproduce the power decline described by literary scholarship. The analysis would compare versioned graph slices before and after the Grand View Garden investigation.

No numerical case-study results are reported in the present installment. The authors explicitly classify H4 as untested under its falsification conditions, leaving unresolved whether the recovered narrative-time graph captures the expected evolution.

References

H3 and H4 remain untested under their falsification conditions.
