R47 Android (Core: 019203de)

• Sync to commit 019203de

This prerelease contains the debug-signed debug APK R47calculator-debug.apk
built by ./scripts/android/build_android.sh from GitHub commit e303945.

The calculator core was synchronized from https://gitlab.com/rpncalculators/c43.git at commit
019203dec5c884c0b25f66e2eaebc568cdb8a81e before the simulator and Android build steps ran.

The Linux host toolchain built xlsxio_xlsx2csv from https://github.com/brechtsanders/xlsxio.git at
commit a9016eb2eb46dcd613a68fcfcd1002b5adf64ae9 to satisfy the upstream font-generation
contract.

Included assets:

• R47calculator-debug.apk
• R47calculator-debug-packaging-evidence.zip

Notes:

• This is a main-branch snapshot prerelease, not a signed store release.
• The included APK is signed with a persistent key for updates.
• The workflow first sanity-checked the authoritative upstream
  simulator core with parallel make test.
• The Android lane rebuilt assets, reran the simulator-native suite
  from ./scripts/android/build_android.sh --run-sim-tests, and then
  packaged the debug APK.
• The workflow verified packaged ABIs and ran the Android 16 KB zip
  alignment check described in the Android docs.
• R47calculator-debug-packaging-evidence.zip preserves the compliance-assets/ directory,
  BUILD-METADATA.txt, SHA256SUMS.txt, ABI/alignment reports, and the
  packaged notice inventory exactly as collected by
  android/collect_packaging_evidence.sh.
