Enum ForgettingModel 

pub enum ForgettingModel {
    Ebbinghaus,
    Linear,
}

Which forgetting curve drives confidence decay (#1).

Variants

Ebbinghaus

Exponential retention R = exp(-Δt / S) with spacing-boosted stability S (Ebbinghaus forgetting curve + SM-2 spacing). Deterministic, the default: durable memories fade gracefully, rehearsed ones persist.

Linear

Legacy linear subtraction, kept for reproducibility / explicit opt-out.
