GN-004
Not applicable here
Any installed UPI app — Category code and note
No mc and tn set, so this is the same payload as the plain control.
Why
Profile P04 is defined by mc and tn, and neither your UPI profile nor this run supplies one — so comparing P04 against P01 would be comparing a method against itself and reading the noise as a finding. Set mc and tn on the profile first, or run P01 and know what you measured.
pa — A payment needs a payee address. Nothing can be launched without pa.
You are on a desktop browser, which has no UPI app to open. The URI is still shown and can be copied.
What would unblock it

Limitations
- This group is the ONLY one that is meaningfully runnable on an iPhone, and even there it depends on an installed app claiming the upi:// scheme.
- Attribution is to whichever app the operator selected, which must be recorded with the result.
Prerequisites
- A saved UPI profile.
