danielhanchen ccac1f0293 Studio sandbox: close ninth-round review bypasses (module table, exec sinks, aliases, budget)
Static classifier:
- deny sys.modules Store/Del: del sys.modules['posix']; import posix drops the guard-patched module for a fresh unwrapped C module
- flag code.InteractiveInterpreter().runcode / InteractiveConsole().runsource as code-object execution sinks (opaque compile results run un-analyzed)
- resolve indirect read-only open callees: from os/io/builtins import open as X (os.open read-only is deliberately allowed outside the workdir, so traversal must be caught statically)
- fold os.path.normpath / abspath on literals so a traversal that only emerges after normalization is scanned
- resolve inline-container-hidden exec/eval: ({'e': exec}['e'])(...) / [exec][0](...)
- normalize the bound one-arg __getattribute__ form obj.__getattribute__('name') (builtins.open.__getattribute__('__closure__'))
- descend into a literal list/tuple argv so subprocess.run(['cat', '/etc/passwd']) is caught
- enforce the analyzer node budget: charge each tree's node count against _MAX_ANALYZER_NODES and fail closed above it (parent-process DoS guard)

Runtime backstop:
- capture and re-pin os.lstat / os.readlink / os.getcwd / os.stat before realpath, since it consults the live symlink helpers -- monkeypatching os.lstat to fail could stop realpath following an in-workdir symlink that points outside
