Device regression — godot-iap rows

Run on 182a6071.

Row            | Device/target              | Flow                                   | Result
Godot iOS      | iPhone 13 mini 35C8EE6D    | export → build → install → launch →    | PASS
               |                            | StoreKit product fetch                 |
Godot Android  | local (make android)       | plugin build, AAR debug+release        | PASS
Godot Android  | Pixel 2 HT79F1A00473       | APK export → install → device flow     | BLOCKED

iOS — PASS. make export-ios succeeded under the installed Godot 4.5.1, framework embedding patched, xcodebuild ... -destination id=35C8EE6D… reported BUILD SUCCEEDED, and the app installed and launched on device. Runtime evidence that the GDExtension actually loaded, not just shipped:

• Device console shows the Swift plugin working — [OpenIapSerialization] purchaseInput received … Successfully decoded and wrapped PurchaseInput on the startup available-purchases pass.
• The in-game Store fetched live StoreKit products with localized pricing: 10 Bulbs ₩1,100, 30 Bulbs ₩4,400, Certified Badge ₩17,000, Premium ₩14,000, Premium Yearly ₩149,000, plus Restore Purchases.
• The packed Martie.pck carries the new config verbatim (include_tags = ["ios", "macos"]) and both GodotIap.framework and SwiftGodotRuntime.framework are embedded as arm64.

No purchase dialog was approved — this run was not authorized for purchase approval, so purchase/finish/consume is not claimed.

Android — plugin build PASS, device flow BLOCKED. make android rebuilt both AARs (Gradle BUILD SUCCESSFUL). make export-android stops at its version gate: the Makefile pins GODOT_VERSION = 4.7.1 for source exports and the machine has the Godot 4.7.1 export templates installed but a 4.5.1 editor binary at /Applications/Godot.app. Exact missing prerequisite: a Godot 4.7.1 editor binary.

Android exposure to this diff is nil by construction — Android loads the AAR through addons/godot-iap/android/GodotIap.gdap, and .gdextension is Apple-only. On Godot 4.3–4.7 include_tags is an unrecognized key that the loader ignores entirely, so runtime behavior is unchanged on every released Godot; only 4.8 gates on it.

Device regression — godot-iap rows (complete)

Godot 4.7.1 was installed to satisfy the Makefile's source-export pin, so the previously blocked Android row now ran. Both rows pass on 182a6071.

Row            | Device                     | Flow                                        | Result
Godot iOS      | iPhone 13 mini 35C8EE6D    | export → build → install → launch → fetch   | PASS
Godot Android  | Pixel 2 HT79F1A00473       | export → install → launch → fetch           | PASS

Android — PASS. make export-android succeeded under Godot 4.7.1 and the APK installed on the Pixel 2 (the old dev.hyo.martie from another example was uninstalled first for a signature mismatch). Device logs show the full path working:

GodotPluginRegistry: Initializing Godot plugin GodotIap
[GodotIap] Native plugin loaded via Engine singleton (Android)
[GodotIap] Android signal connection complete
[IAPManager] GodotIap connected
[GodotIap] fetch_products called
[IAPManager] Products fetched (async): 5

No gdextension loader messages appear anywhere in the Android log, confirming the Apple-only extension is inert on that target and that the include_tags key changed nothing there.

iOS — PASS, as reported above: StoreKit returned all five products with localized pricing and the Swift plugin decoded purchases at startup.

No purchase dialog was approved on either platform, so purchase/finish/consume is still not claimed. Product fetch, plugin load, and billing connection are covered on both.
