Validate EdgeGenBench on an Android 16 KB runtime

[triasha72]

Summary

• run EdgeGenBench v0.1.7 through the Kotlin/JNI/reference path on an Android 15 API 35 ARM64 emulator reporting PAGE_SIZE=16384
• retain ten cold-launch evidence runs with logcat, launch, memory, thermal, CSV, and screenshot artifacts
• verify every machine-readable result reports runtime_page_size_bytes=16384, zero preprocessing/output drift, the reference backend, and disabled fallback
• fix the repeated-profile collector to match the stable v0.1.7 backend log and wait for benchmark_json before retaining each run
• promote the portfolio lane from runtime-pending to validated_16kb_emulator_runtime

Verification

• zipalign -c -P 16 -v 4 app-debug.apk: passed
• arm64-v8a and x86_64 ELF PT_LOAD alignment: 0x4000
• Android runtime: adb shell getconf PAGE_SIZE → 16384
• ten of ten retained logcat files contain runtime_page_size_bytes=16384
• five portfolio acceptance tests passed
• repository-wide Ruff format and lint passed
• Android lint, JVM tests, native builds, and APK assembly passed

Claim boundary

This closes the Android 16 KB runtime-compatibility gap for the reference APK/JNI path. It is emulator compatibility evidence, not physical-device performance, Qualcomm QNN APK placement, thermal, energy, or power evidence. The supported-Snapdragon APK run and calibrated power measurement remain hardware-only gaps.
