01 / WHAT WE TRACK

How much can DNA tags reveal about which RNAs appeared in which cells?

03 / EDITORIAL READING

Known strains can be tested in parallel. A mammalian version could separately record viral RNA and the host response to help track recovery.

04 / WHAT REMAINS UNKNOWN

A general detection limit, time to result and Detectron performance in mammalian cells remain open.

05 / NEXT CHECK

Test rare infections, cross-reactivity with related sequences and single-cell tag recovery and retention.

A hypothesis to keep honest

HYPOTHESIS · NOT YET TESTED

Separate records of infection and immune response could help track which airway cells recover.

What would change our view: The approach would not resolve recovery if tags are lost or the sensor changes the immune response.

A prospective test proposal, not a prediction score. A graph connection does not validate this hypothesis.
