Struct LifecycleSection 

pub struct LifecycleSection {
    pub forget_enabled: bool,
    pub forget_min_age_days: u32,
    pub forget_usefulness_floor: f32,
    pub forget_protect_use_count: u32,
    pub regret_flag_threshold: u64,
    pub proposal_expiry_days: u32,
    pub proposal_auto_accept_confidence: f32,
}

F3 lifecycle / forgetting policy configuration.

All settings are gated behind forget_enabled = false by default so existing installs are completely unaffected until an operator opts in.

#[serde(default)] keeps all existing project.toml files loading cleanly.

Fields

forget_enabled: bool

Master opt-in switch. Default false — forgetting is NEVER triggered without the operator explicitly enabling it.

forget_min_age_days: u32

Minimum age (days) before a memory is eligible for archival. Only memories whose last_useful_at (or created_at when never cited) is older than this many days are considered. Default 90.

forget_usefulness_floor: f32

Usefulness floor: memories with usefulness_score / max(use_count, 1) <= this value are candidates. Default -0.1 (net-negative).

forget_protect_use_count: u32

Evergreen protection threshold. Memories with use_count >= forget_protect_use_count are NEVER archived regardless of their usefulness ratio. Default 10.

regret_flag_threshold: u64

Number of retrieval.regret events a memory must accumulate before it appears in the review list. Default 5.

proposal_expiry_days: u32

Number of days before a pending proposal is auto-expired (rejected with reason “expired”). Default 30. 0 disables expiry.

proposal_auto_accept_confidence: f32

Proposals with proposed_confidence >= this value are auto-accepted during the hygiene pass. Default 1.1 (disabled — threshold above the maximum possible confidence of 1.0).
