openresearch 90951d3c9a docs: octagon principle → P vs NP experimental program
The octagon framing bisects P vs NP:
- Works for all natural NP → P=NP via spectral methods
- Fails for some natural NP → natural P≠NP witness
- Exponential embedding only → new complexity boundary

Either way, a question is cleared.

Current data:
- Sidon: YES (4/4 measured)
- Graph coloring: YES (Hoffman bound, known)
- Graph isomorphism: NO (cospectral non-isomorphic graphs exist)
  — but GI is in P (Babai 2015), so this doesn't resolve P vs NP

Next to test (the experimental program):
1. 3-SAT (clause-incidence matrix → satisfiability spectral?)
2. Hamiltonian path (adjacency eigenvalues vs Hamiltonicity?)
3. Clique number (Lovász theta — is the bound tight?)
4. Subset sum (sum matrix → target reachability?)

Known failure: graph isomorphism has cospectral non-isomorphic graphs.
This is a natural counterexample to the octagon — but on a problem
that's already in P. The real question: does the octagon fail on an
NP-COMPLETE problem?

This is an experiment, not a proof. Systematic measurement with
clear yes/no outcomes per problem.
