[#R280] Prove total unimodularity
1Summary
Seek a consecutive-ones ordering, network-matrix representation, or Ghouila-Houri signing for all rows of M_n.
A proof would settle every minor at once. The irregular Fibonacci anti-diagonals make standard interval criteria hard to apply.
Conjectured evidence. Replay readiness: source only.
2Outcome
Evidence package: source only
