• Fix the release failure in run https://github.com/wizdom13/WizeFiles-Pro/actions/runs/36765431427: all three APKs build and sign successfully, but collection fails because SIGNED_RELEASE_FILES is empty.
• The r0adkll/sign-android-release@v1 bundled lib/main.js exports only the last signedReleaseFile, despite declaring a plural output in its metadata. Collect the actual *-signed.apk files from the freshly built staging directory instead.
• Remove the unavailable action-output dependency from both production and PR packaging workflows. Preserve the existing signing key, filenames, strict three-file requirement, package/architecture checks and signature verification.
• Add regression coverage for absent action outputs, unsigned/aligned files and signing-key exclusion, missing/unexpected/stale APKs, and propagation of signature-verification failures.
• Local validation: all 11 tests pass; shell syntax, workflow YAML parsing and whitespace checks pass. Android PR CI also passed. The full packaging run https://github.com/wizdom13/WizeFiles-Pro/actions/runs/36769648271 was cancelled during compilation before signing, collection or upload, so end-to-end validation remains pending a new run.
• Existing run measurements, before signing: universal 138,324,704 bytes (131.92 MiB), ARM64 78,029,242 bytes (74.41 MiB), ARM32 77,507,344 bytes (73.92 MiB). Final production-signed measurements remain pending a successful release run.
