# Tests for issue #91 — Android APK secrets lens.
#
# Behavioural contract:
#   - android/secrets-in-apk exists and is registered in config/domains.json.
#   - Shell examples use the exported runtime APK path variable, not direct
#     template interpolation of the APK path inside commands.
#   - Decode output goes under a private per-run scratch tree and is cleaned up,
#     never fixed shared paths for secret-bearing APK contents.
