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.

CRED

CR-007 Android only

CRED — Minimum amount

No mam set, so this is the same payload as the plain control.
Why
Profile P07 is defined by mam, and neither your UPI profile nor this run supplies one — so comparing P07 against P01 would be comparing a method against itself and reading the noise as a finding. Set mam 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.
Addressing one named app from a browser needs an Android intent URI, and you are not on Android. There is no iOS equivalent for this app.
What would unblock it
Open the lab on an Android phone, or use the Generic UPI (GN) group here.

mam constrains an amount the payer may edit. Beside a fixed am it is contradictory, and WHICH ONE each app honours is the finding. The lab warns about the contradiction and sends it anyway — that is the experiment.

Expected

CRED opens on its payment confirmation screen showing the payee and ₹2.00. mam constrains an amount the payer may edit. Beside a fixed am it is contradictory, and WHICH ONE each app honours is the finding. The lab warns about the contradiction and sends it anyway — that is the experiment.

Limitations

  • A browser cannot tell you whether an app is installed. "App did not open" and "app is not installed" look identical from here; AN-004 in the Android harness is what separates them.
  • Not runnable on iOS at all through this method.

Prerequisites

  • A saved UPI profile with a payee address.
  • On iOS: not addressable — CRED publishes no URI scheme the lab is willing to claim. Use the Generic UPI group (GN) on iPhone.
  • On Android: CRED installed (com.dreamplug.androidapp).

Notes

  • CRED publishes no URI scheme the lab is willing to claim, so it cannot be addressed directly from a non-Android browser.

How the lab runs it

Android: an intent:// URI naming com.dreamplug.androidapp, with no browser_fallback_url so a failure to open stays visible. iOS: not implemented, because no scheme exists to implement.
