IO-001
Needs the native harness
Companion iOS harness — Standard merchant intent
pa — A payment needs a payee address. Nothing can be launched without pa.
This measures something a browser cannot observe — installed apps, an activity result, an app version. It needs the companion harness.
What would unblock it
The harness is specified in docs/NATIVE_HARNESS.md and has not been built. Until it exists this slot is planned, not runnable.
Parameters

The control. Every other profile is this one plus something, so a failure here is a failure of the destination or the app, never of an optional field.
Expected
Whether any installed app claims the upi:// scheme. Requires the scheme to be listed in LSApplicationQueriesSchemes; an undeclared scheme always answers false, which is indistinguishable from "not installed".
Limitations
- NOT RUNNABLE FROM A BROWSER, AND THE HARNESS DOES NOT EXIST YET. Counted in the planned 166 and excluded from the runnable count.
- iOS restricts scheme queries far more tightly than Android; several questions that are answerable on Android are not answerable at all here.
Prerequisites
- The companion iOS harness, which is SPECIFIED BUT NOT YET BUILT (docs/NATIVE_HARNESS.md).
- A physical iPhone with the payment apps installed.
- An Apple developer account to sideload it.
Notes
- This method has no browser launch mechanism.
