RPE-CIDM-002 · UNKNOWN CALIBRATION
What does “Pathogen: Not specified / mixed” actually mean?
We test whether “unknown” belongs to Reality, the paper's scope, or the current representation/classifier.

no safe title-level signalCritical distinction: “Not specified / mixed” is not one kind of unknown. It can mean classifier-missed pathogen, genuinely multi-pathogen scope, method/system paper, or insufficient metadata.

Experimental propagation
Applying only single clear title signals in a cloned branch changed 240 records, produced 552 pathogen×technology route membership changes, and altered 42 aggregate pathogen Journey signatures. Canonical records remain untouched.
Unknown taxonomy v0.1
U1 Representation Unknown — evidence is visible but classifier missed it.
U2 Mixed Reality — multiple pathogens legitimately coexist.
U3 Scope-Not-Applicable — a pathogen label may be inappropriate.
U4 Evidence-Insufficient — metadata cannot safely resolve it.
U5 Reality Unknown — the underlying scientific question itself remains unresolved.
