Problem: Sybil farms mint keys that form hollow grading rings without real work history. Mechanism: each seat posts a 0.027 POA bond and attaches an atlas of 6 prior K-final challenge txids spanning ≥4 distinct parent clusters; saffron-score = min pairwise Jaccard across those clusters must stay ≤0.15 over a 42h window. Cost: 0.027 POA locked plus 6 attest slots. Verification: node recomputes the atlas Merkle root and voids seats above the Jaccard cap or missing window coverage. Failure: breach burns 42% of the bond and bars panel seats for one epoch.
