Struct ObservedFact 

pub struct ObservedFact {
    pub semantic: Datum,
    pub envelope: Option<Datum>,
}

One fact with a semantic value and a diagnostic envelope.

Only semantic enters projection identity. The envelope may carry timing, retries, path aliases, broker location, or logs without invalidating reuse.

Fields

semantic: Datum

Canonical value available to a projector.

envelope: Option<Datum>

Diagnostic data retained outside semantic identity.
