The rebase onto upstream 3.1 (mypy + ruff I001/F401 waves) left the tree short of the newly enforced baselines in three ways: * contextlib / UbridgeError imports dropped as false duplicates during conflict resolution left NameErrors in iou_vm and qemu_vm (F821); the Dynamips router grabbed the compute-level NIOTAP instead of the hypervisor one, breaking TAP anchoring (test failure). * unused imports (KERNEL_UNSUPPORTED_FILTERS, UbridgeError, List) and unsorted blocks left behind where the stack's later commits moved the last usage elsewhere — ruff I001/F401/RUF022 now enforce these. * mypy, now baseline-free: cache dict annotations in tc_probe, the locators candidate list, the resolved-params None branch in the MCP runner, and validate_bpf_syntax keeps the upstream Dict[str, Any] return (the strict Optional[str] was wrong for the "valid" bool entry). The e2e raw-frame probe resolves its compiler via shutil.which (S607) and zips with strict= (B905); the remaining subprocess call is S603 by nature and gets a per-file ignore like other test files. ruff check/format clean, mypy at upstream parity (no new errors), full unit suite 2167 passed.
