Statically investigate the actual shipped APK at {{artifact_path}} using only the registered REA tools. Report the exact artifact SHA-256, package name, version name/code, every class-name match for the case-sensitive substring MainActivity, and all onCreate method descriptors reported for org.schabi.newpipe.MainActivity. Preserve reported signatures and explicit unknowns. For each onCreate entry include reported_signature, overload_index and dex_descriptor exactly as reported, preserving null. Final answer must be JSON with artifact_sha256, package_name, version_name, version_code, matches, onCreate, evidence_ids, limitations. Include real Evidence IDs supporting each result. Do not execute the APK or use shell, host file tools, network or other agents. Stop once these facts are supported.

When a client JavaScript executor is available, compose the required REA calls in one execution and return only selected facts from normalized_result, real Evidence IDs, target identity from subject.digest.sha256 and limitations. Parse original MCP text content if necessary. Do not return raw_result, whole Evidence or unrelated inventories. All matching classes and onCreate overloads must still be included.
