What clock is actually being shortened?

Clock	Inside the ~2h claim?	Why it matters
Time to first positive blood culture	No	The bottle must still incubate until positive
Gram stain / ID from a separate method	No	Identity still has to meet the susceptibility report
Cartridge load → susceptibility results	Yes	This is the assay window being compressed
Transport, staffing, chart posting, antibiotic change	No	Door-to-door sepsis care is not the assay stopwatch
Commercial availability in your hospital	No	Cleared is not the same as ready to buy everywhere

The invent hinge is not “AI beat bacteria.” It is: once positivity exists, a right-drug map can arrive on a same-shift laboratory clock for covered Gram-negative monomicrobial cases — invent how wards, pharmacies, stewardship teams, rural labs, or community follow-up could use that earlier map.
