Enum Observation 

pub enum Observation {
    Corroborating,
    Contradicting,
}

What one observation says about a claim.

The two directions differ by more than the sign of a count. Corroboration is the belief being seen again, so it restarts temporal decay; a contradiction is not, so it must leave the decay anchor exactly where it stands. Carrying that as a value — rather than leaving each write site to remember it — is what stops “this is wrong” from making a stale edge more visible than it was: an edge stored at 0.6 and decayed to 0.3 would otherwise come back at 0.545, undecayed, because it was corrected.

Variants

Corroborating

The claim was stated again.

Contradicting

The claim was denied.

Implementations

impl Observation

pub fn renews_decay_anchor(self) -> bool

Whether recording this observation restarts temporal decay.

Only corroboration does. This is the single place that rule lives.
