Struct RecallScoringConfig 

pub struct RecallScoringConfig {
    pub half_life_days_short: Option<f64>,
    pub half_life_days_mid: Option<f64>,
    pub half_life_days_long: Option<f64>,
    pub legacy_scoring: bool,
}

Per-tier half-life (days) overrides loaded from [scoring] section of config.toml.

The half-life is the number of days it takes for a memory’s recall score to drop to 50% of its undecayed value. Shorter half-lives prioritize fresh memories; longer half-lives give older memories more weight. Defaults are chosen so each tier’s decay curve matches its retention expectations: short memories decay quickly (7 d), mid moderately (30 d), long slowly (365 d).

Setting legacy_scoring = true disables the decay multiplier entirely, restoring the pre-v0.6.0.0 blended-score behavior for A/B comparison or if a recall-quality regression is reported.

Fields

half_life_days_short: Option<f64>

Half-life for short-tier memories, in days (default 7).

half_life_days_mid: Option<f64>

Half-life for mid-tier memories, in days (default 30).

half_life_days_long: Option<f64>

Half-life for long-tier memories, in days (default 365).

legacy_scoring: bool

When true, skip the decay multiplier entirely. Default false.
