Struct UserInjectionProfile 

pub struct UserInjectionProfile {
    pub user_id: String,
    pub effective_threshold: f32,
    pub positive_signals: u32,
    pub negative_signals: u32,
    pub updated_at: DateTime<Utc>,
}

Per-user adaptive injection profile

Fields

user_id: String

effective_threshold: f32

Effective threshold (starts at default, adapts over time)

positive_signals: u32

Count of positive signals received

negative_signals: u32

Count of negative signals received

updated_at: DateTime<Utc>

Last update timestamp

Implementations

impl UserInjectionProfile

pub fn new(user_id: String) -> Self

pub fn adjust(&mut self, signal: FeedbackSignal)

Adjust threshold based on feedback signal

• Positive: lower threshold by 0.01 (min 0.50)
• Negative: raise threshold by 0.02 (max 0.90)
• Neutral: no change

Asymmetric adjustment: we’re more cautious about noise

pub fn signal_ratio(&self) -> f32

Get signal ratio (positive / total)
