### Fixed

- **security:** treat legacy `httplib` pickle globals the same as `http.client`, including import-only and `REDUCE` findings in standalone and archived payloads
- **security:** detect import-only pickle `GLOBAL`/`STACK_GLOBAL` references while preserving safe constructor imports and avoiding mislabeling executed call chains as import-only
- **security:** harden TensorFlow weight extraction limits to bound actual tensor payload materialization, including malformed `tensor_content` and string-backed tensors, and continue scanning past oversized `Const` nodes
- **security:** stream TAR members to temp files under size limits instead of buffering whole entries in memory during scan
- **security:** inspect TensorFlow SavedModel function definitions when scanning for dangerous ops and protobuf string abuse, with function-aware finding locations
