Struct Historical 

pub struct Historical<'a, 'token> {
    pub index: usize,
    pub current: &'a CheckedTimestamp<'token>,
    pub selection: &'a Selection<'token>,
    pub following: Option<&'a Evidence>,
    pub following_chain: Option<&'a Evidence>,
    pub verification_time: Instant,
}

Facts for historical validation, never a request to infer trust from genTime.

Fields

index: usize

Original flat timestamp ordinal.

current: &'a CheckedTimestamp<'token>

Complete common result for the actual selected original token.

selection: &'a Selection<'token>

Candidate/key used by this same common check.

following: Option<&'a Evidence>

Next token’s successful mathematical facts, when present.

following_chain: Option<&'a Evidence>

First token of the next chain: the tree algorithm must remain suitable through this renewal, even for earlier tokens in the current chain.

verification_time: Instant

Explicit current verification reference for the final timestamp.
