Coarse → Fine Feature Decomposition

3 coarse France-related SAE features (16K) and the 6 fine sub-features (262K) they correspond to
Link width = activation correlation  ·  Link color = decoder cosine similarity

Decomposition Graph
Metric Space — All 15 Pairs
cos sim > 0.3 — true sub-feature
cos sim 0.05–0.3 — partial overlap
cos sim < 0.05 — co-occurrence only
Link width scales with activation correlation (behavioral co-firing)
