no aligned release found
No measured release of PyTorch Android lite is 16 KB-aligned. The newest measured version, 2.1.0, is still offending.
- Sampled, not exhaustive: 9 of 9 published versions were measured with native code; unmeasured versions in between are unknown.
Measured evidence
| Version | Library file | p_align | File date | Source | |
|---|---|---|---|---|---|

p_align is the smallest PT_LOAD segment alignment of the ELF. 16 KB-compatible needs at least 16384 (2^14). Method: min PT_LOAD p_align of arm64-v8a/x86_64 .so inside the published AAR/JAR; aligned = >=16384 for every lib. Dates are repository file times, not official release dates.

The Gradle change
no 16 KB-aligned release of org.pytorch:pytorch_android_lite measured (latest measured 2.1.0); ask the vendor, check for a fork, or re-link the .so yourself; replacing is the last resort
Confirm what Gradle actually resolves, since another dependency may pull an older version:
./gradlew :app:dependencyInsight --dependency pytorch_android_lite --configuration releaseRuntimeClasspathRe-verify it yourself
