Struct FingerprintEngine 

pub struct FingerprintEngine { /* private fields */ }

Engine that ingests behavior samples and computes agent fingerprints.

Implementations

impl FingerprintEngine

pub fn new() -> Self

Create an empty fingerprint engine.

pub fn ingest(&mut self, sample: BehaviorSample)

Ingest a new behavior sample.

pub fn get_fingerprint(&self, agent_id: &str) -> Option<AgentFingerprint>

Compute the fingerprint for a given agent, or None if no samples exist.

pub fn detect_anomaly( &self, agent_id: &str, sample: &BehaviorSample, ) -> AnomalyResult

Detect whether a new sample is anomalous relative to the agent’s baseline.

Checks:

• Response time > 2x the baseline mean
• Error rate > 3x the baseline rate (inferred from a single failing sample)
• Confidence drop > 0.2 below the baseline mean

pub fn similarity(&self, a: &str, b: &str) -> f64

Compute a similarity score (0.0 to 1.0) between two agents.

Compares evidence distribution, confidence mean, error rate, and average response time. Returns 0.0 if either agent has no samples.
