ZeroState System Evolution:
S(t+1) = F(S(t), I(t), C(t), H(t))
where:
- S(t) ∈ ℝⁿ = System state vector at time t
- I(t) ∈ ℝᵐ = Input vector at time t
- C(t) ∈ 𝒞 = Capability authorization vector at time t
- H(t) ∈ ℋ = Hardware state vector at time t
- F: ℝⁿ × ℝᵐ × 𝒞 × ℋ → ℝⁿ = Verified state transition function
Persistence Mathematical Framework:
P(S) = E_k(Compress(Serialize(S, Integrity_Proof(S))))
where:
- E_k: Data → CipherText (Quantum-resistant encryption with key k)
- Compress: Data → CompressedData (Advanced compression algorithm)
- Serialize: SystemState × Proof → SerializedData (Cryptographic serialization)
- Integrity_Proof: SystemState → MathematicalProof (Mathematical integrity proof)
Recovery Verification Function:
R(P) = Verify(D_k(Decompress(Deserialize(P))))
where:
- D_k: CipherText → Data (Quantum-resistant decryption)
- Decompress: CompressedData → Data (Decompression algorithm)
- Deserialize: SerializedData → SystemState × Proof (Deserialization with integrity)
- Verify: SystemState × Proof → Boolean (Mathematical verification)

Persistence Security Theorem:
∀adversary A with computational_power < 2^256:
