Scope-aware alias resolution (replaces the flat, module-wide alias maps):
- A new per-scope index resolves shell-sink, exec-builtin and compiled-code aliases
with Python lexical scoping. This fixes two problems the flat maps had: a safe
`c = compile('1+1')` in one function no longer shadows a dynamic `exec(c)` in
another (a real bypass), and a `s = os.system` in one function no longer makes a
benign `s = print` call in another look like a shell sink (a false positive), while
still catching a genuine function-local sink and honoring local shadowing of a
module-level alias.
Runtime realpath backstop:
- io.FileIO now passes the MATERIALIZED fspath to the real constructor (a stateful
__fspath__ could otherwise return an outside path to the C constructor).
- Deny an integer fd path for the mutating single-path wrappers (os.chmod(fd) etc.):
a read-only fd opened on an outside file could otherwise mutate host metadata.
Constant-folder allocation DoS:
- Refuse dynamic printf widths/precisions ('%*s', '%.*f') that draw their size from a
runtime argument.
- Bound str.replace / str.join output before it allocates (a long replacement over
many occurrences, or joining many long parts, can build a multi-gigabyte string).
Static classifier:
- Flag builtins / a sensitive module reached through the namespace dict:
globals()['__builtins__'], locals()[...] and globals()['os'].
Adds regression tests across the aliasing, runtime-backstop, const-fold and classifier
suites for every item above.
