Use Bionic arc4random_buf for the older Android API route and retain the existing getentropy initializer from API 28. Register the real function address in the ARM32 interpreter so loaded SplitMix objects can resolve it.
Both ABI controls verify API26 compilation and linking against the actual NDK headers and providers, and API35 object equality. Final source checks use native LLVM21; exact final NDK18 and production package-tar validation remain for CI after local VM startup failures.
Scope the scheduling opt-out to the patched QEMU versions, patch the interpreter source before planning, and expose the real static Bionic and GNU iconv symbols. Use the RTS package dependency for Android libffi.
The production interpreter reaches Haskell main on Rosetta and native ARM64 QEMU. Normal target TH, the ARM32 shared export, a C caller returning 42, and upstream annotations pass. Profiling execution is not yet validated.
