Operations testing: Encryption/decryption, homomorphic add/mul, and dual-track RNS operations all passed across multiple configs.
Audit remediation (2026-02-06): All prior audit caveats have been resolved. Floating-point usage has been fully eliminated from the entire stack (zero f64/f32 anywhere). Auto mod-switch now enables deeper public-mode circuits at level 3+. The nine65-python and nine65-wasm FFI crates have been added and validated.

Bootstrap-Free Advantage: Traditional FHE requires bootstrapping every 5-10 multiplications (100-1000ms each). NINE65's exact K-Elimination rescaling eliminates this entirely.

Post-Quantum: LWE-based security is resistant to Shor's algorithm. These estimates represent rough Core-SVP + GSA bounds. For formal guarantees, independent audits are recommended.
V5 Architecture
Key Features
- CSPRNG: OS-seeded cryptographically secure RNG for all key generation

- Dual-RNS: Main + anchor primes for exact rescaling after tensor products
- Auto Mod-Switch: Automatic modulus switching at level 3+ for deeper public-mode circuits
- Zero Float: Entire stack verified free of f64/f32 usage after audit remediation
Test Environment (Baseline 2026-02-06)
- OS: Debian Linux 6.12.48, x86_64
- CPU: Intel Core i7-3632QM @ 2.20GHz (4C/8T)
- Rust: 1.90.0, release mode

Comparison Notes
- Traditional FHE comparisons based on published SEAL/OpenFHE benchmarks
- Bootstrapping overhead estimates: 100-1000ms per bootstrap in traditional systems
- Results vary by hardware; production configs (secure_128+) have different timing profiles
