Struct DecayConfig 

pub struct DecayConfig {
    pub enabled: bool,
    pub base_half_life_secs: f64,
    pub decay_shape: f64,
    pub min_retention: f64,
    pub rehearsal_factor: f64,
}

Configuration for the Ebbinghaus-inspired memory decay / forgetting curve.

When enabled, older memories are deprioritized during search and dedup via a stretched-exponential retention factor. Memories that are accessed frequently decay more slowly (spaced-repetition effect).

Fields

enabled: bool

Master switch. When false (the default), all scoring is unmodified.

base_half_life_secs: f64

Base half-life in seconds before any rehearsal bonus. Default: 7 days.

decay_shape: f64

Stretched-exponential shape parameter (0 < gamma <= 1). Lower values produce slower initial decay with a steeper tail.

min_retention: f64

Minimum retention floor so no memory ever fully vanishes.

rehearsal_factor: f64

How much each access (rehearsal) increases memory stability.
