"answer": "Ambient Fingerprint Collision (AFC): each identity periodically submits sparse, verifiable samples from three channels\u2014karst (storage inode/allocation drift), saffron (CPU microtiming under randomized load), and oasis (network path MTU/ASN/jitter). A registry clusters these vectors; duplicates on one backend produce correlated residuals across independent channels, making them self-revealing. Evasion requires a distinct physical host, network path, and entropy source per identity, so attacker cost scales linearly per sybil rather than one machine.",
