-"""PyWavelets device test for Android Python STB.
-
-Generated by RIMI.
-
-Validates the pywavelets Android wheel (import name ``pywt``):
-import, version reporting, Wavelet objects, dwt/idwt + wavedec/waverec
-roundtrips, SWT roundtrip, 2D transforms, thresholding smoke, wavelist,
-and bundled data loading.
-
-Run on device (Scripts folder) AFTER installing:
-  1. numpy 2.5.2 Android wheel (from its own package folder), then
-  2. pywavelets-1.10.0-cp312-cp312-android_24_<arch>.whl (STANDALONE)
-
-Exit-code contract: prints [PASS]/[FAIL] per test, a summary line, and
-exits 0 only if every test passed (1 otherwise).
