Research direction
Start with the crash path at filesystem/compressed/sevenz/LZMA2Decoder.java:39 and follow it through SevenZFile.java, SevenZipExtractor.kt:69, and ExtractService.java:318. Reproduce 7zip extraction on Android and determine where memory usage exceeds the limit. Done means the reported archive can be decompressed without an OutOfMemoryError.
