Why it matters
It is the only way to reach these profiles and results from another device. The lab stores a hash of it, so nobody here can recover it for you.

Any installed UPI app

GN-002 Not applicable here

Any installed UPI app — With transaction note

No tn set, so this is the same payload as the plain control.
Why
Profile P02 is defined by tn, and neither your UPI profile nor this run supplies one — so comparing P02 against P01 would be comparing a method against itself and reading the noise as a finding. Set 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
Open this page on the phone you want to test, or use a QR-scan method (QR group) which is designed for exactly this situation.

Whether a note is displayed, truncated, stripped or rejected. Note length limits differ sharply between apps.

Expected

The OS offers the installed UPI apps; the one you pick opens on its payment screen. Whether a note is displayed, truncated, stripped or rejected. Note length limits differ sharply between apps.

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.

How the lab runs it

An anchor whose href is upi://pay?… built from P02.
