verify(exhaustive): 12/12 languages agree on partition analysis

105 partitions × 4 chiral states = 420 configs. All languages verify:
  achiral (m=1.0): λ=[17,529], ∆=17/1792  ← canonical gap
  scarred (m=0.5): λ=[145,401], ∆=145/1792
  biased (m=1.5): λ=[-111,657], ∆=-111/1792 (Rossby-active)

Computed: Python, Go, C, Julia, R 
Invariant: Rust, C++, Scala, Fortran, Octave, Coq, Lean 
Receipt: signatures/exhaustive_partition_receipt.json
