Static classifier:
- fix scope-local walker so a nested def/class reassigning an alias name no longer inflates the outer single-assignment count and drops a real module-level sink alias
- track non-bare compile aliases (builtins.compile, from builtins import compile as comp) for the types.FunctionType(c) code-object gadget
- block child-process file writers at shell command position (touch/tee/cp/mv/mkdir/install/truncate/mkfifo/mknod/shred/unlink): a spawned child runs without the in-process write guard
- expand a literal **{...} unpack in the read scanner so open(**{'file': '../../etc/passwd'}) is resolved
- resolve a pathlib expression bound to a single-assignment name before read methods (p = Path('..')/'etc'/'passwd'; p.read_text())
- keep a wrapper's separated option argument in command position so stdbuf -o L python -c ... still detects the interpreter (env -i rm still caught; no FP on grep patterns)
- treat object.__getattribute__ / type.__getattribute__ as attribute obfuscation, covering gadget dunders and sensitive-module attrs (also closes __closure__ recovery of a guarded wrapper's original callable)
- block runpy.run_path / runpy.run_module execution sinks
- treat shutil.copy*/move SOURCE as a read callee so a .. traversal source is caught
Runtime backstop:
- normalize a bytes realpath (fsdecode) before the workdir prefix compare so a legitimate in-workdir bytes write is not denied by a TypeError; outside bytes writes still denied
