Struct FoldResult 

pub struct FoldResult {
    pub head: Option<usize>,
    pub gap: bool,
    pub anchored: bool,
}

The outcome of folding one entity’s editions.

Fields

head: Option<usize>

Index (into the input slice) of the chosen head edition, or None if nothing ≥ floor.

gap: bool

A higher version exists but doesn’t link contiguously to the head — withheld prereqs. The caller fails CLOSED for the entity (suspends its authority) and refetches (H1/M8).

anchored: bool

The BASE anchor test passed: the lowest ≥-floor edition is a genesis, our exact held floor edition, or chains directly to it. When true, head is a chain-verified extension of the committed floor even if gap flags withheld versions ABOVE it — adopting that verified prefix is sound (refuse-downgrade holds). When false, head is unanchored: do not adopt.
