- reject overlong size varints with InvalidData instead of shift overflow - reserve result buffer incrementally and cap output at declared result size - reuse delta_decode in Pack::rebuild_delta_with_hash and return GitError - propagate delta rebuild failures from thread pool through SharedParams - add regression tests for varint overflow, unallocatable sizes, output-size overruns, and malformed pack delta objects
