Crate cpop_jitter 

Proof-of-process primitive using timing jitter for human authorship verification.

Two engines: PureJitter (HMAC-based, economic security) and PhysJitter (hardware entropy, physics security). HybridEngine selects the best available source with automatic fallback.

use cpop_jitter::{HybridEngine, PureJitter, PhysJitter, Evidence};

let engine = HybridEngine::new(PhysJitter::default(), PureJitter::default());
let secret = [0u8; 32];
let (jitter, evidence) = engine.sample(&secret, b"keystroke data").unwrap();
println!("Jitter: {}us, Physics: {}", jitter, evidence.is_phys());

Supports no_std via PureJitter with explicit timestamps. The std feature enables HybridEngine, PhysJitter, and Session.
