+      GPT-5.5 Pro (prover) + Claude Code (assembler) pipeline producing
+      solutions to open problems (COLT, FOCS, Erdős, commutative ring theory)
+      with Lean 4 formalization. Solves Erdős Problem 477 (tiling complement)
+      — the same problem and greedy algorithm as SilverSight's crt_sidon_set.
+      Their prover-verifier pipeline mirrors SilverSight's autoresearch
+      (phi4/prove.py -> lake build verification). 95% of repo is Lean 4.
