Devin AI 5cacb86ddb feat(lean): close sidon_iff_zero_collision (both dirs) and erdos30_e8_conditional ... Close 3 sorry tokens (forward, backward, erdos30): - sidon_iff_zero_collision forward: double-inclusion proves filter = same∪swap, inclusion-exclusion gives card = (2k-1)k exactly. - sidon_iff_zero_collision backward: cardinality squeeze shows filter = same∪swap when excess=0, then classify each element via same/swap membership. - erdos30_e8_conditional: difference injection into Icc 1 N + trichotomy partition gives k(k-1) ≤ 2N, contraposition via nlinarith closes the bound. E8Sidon sorry count: 9 → 6 (across 6 theorems). All remaining sorries documented with TODO(lean-port).
