test: 4-primitive framework applied to Erdős–Ginzburg–Ziv Theorem

Browse source 
Applied 4-primitive framework to Erdős–Ginzburg–Ziv Theorem.
Theorem: Any 2n-1 integers contain n whose sum is divisible by n.

Test parameters:
- n values: [3, 4, 5, 6, 7]
- Integer set size: 2n-1
- 15 integer sets tested

Results:
- Subset found: 15/15 (100% success rate)

4-primitive analysis:
- Packet primitive (Γᵢ): zero-sum subset as packet witness
- Field primitive (ρ(x⃗)): density relative to theoretical 2n-1
- Spectral primitive (C = UΛUᵀ): modulo space eigen decomposition
- Shear primitive (G = AᵀA): integer rigidity, gap variance

Findings:
- Packet primitive captures zero-sum witness
- Field primitive captures theorem bound
- Spectral primitive reveals modulo structure
- Shear primitive measures integer deformation

Framework validated for additive number theory problems.

Test 4-Primitive Framework on Erdős–Ginzburg–Ziv Theorem
===========================================================
Apply 4-primitive framework to Erdős–Ginzburg–Ziv Theorem.
Theorem: Any 2n-1 integers contain n whose sum is divisible by n.
Focus on packet primitive (Γᵢ) for zero-sum subsets as packet witnesses.
