Struct L0Snapshot 

pub struct L0Snapshot {
    pub pins: Vec<(String, String)>,
    pub pick_counts: Vec<(String, String, u32)>,
    pub layer_prefs: [f64; 6],
}

Persistent state of the L0 layer. Caller serializes / deserializes this however it likes (TOML, MessagePack, sqlite, …) — the crate intentionally has no serde dependency.

Fields

pins: Vec<(String, String)>

(code, word) pairs the user has pinned (manually or via record_pick reaching threshold).

pick_counts: Vec<(String, String, u32)>

(code, word, count) — pending pick counts that haven’t yet reached PROMOTE_THRESHOLD. Snapshot semantics are best-effort; a count of threshold - 1 restored after restart needs only one more pick to promote.

layer_prefs: [f64; 6]

Layer multipliers, indexed by Layer as usize.
