Two final bypass classes from the round-5 follow-up list are now
closed (552 tests passing):
1. Bash glob under a sensitive root. ``cat /etc/sha*ow``, ``cat
/etc/sh?dow``, ``cat /etc/*``, ``cat ~/.ssh/id_*`` -- the shell
expands ``*`` / ``?`` against the filesystem at runtime, so the
literal-path scan never sees ``/etc/shadow``. A new
``_SENSITIVE_ROOT_WITH_GLOB_RE`` mirrors the existing
``_SENSITIVE_ROOT_WITH_EXPANSION_RE`` (which gates ``$(...)`` /
backtick substitutions) for the ``*`` / ``?`` family. The
``[^\s'\";&|`$]*`` literal-text-only constraint keeps the match
attached to the sensitive root token, so ``find /etc/ -name
'*.conf'`` (whitespace between root and glob) and project-local
globs like ``./src/*.py`` stay allowed.
2. Ternary ``IfExp`` branches. ``open('/etc/shadow' if cond else
'data.txt')`` previously slipped because
``_extract_string_from_node`` had no ``ast.IfExp`` handler.
Either branch can execute at runtime; the gate now resolves both
branches and prefers the sensitive one (via the same
``_looks_sensitive`` check that backs the binding-bias) so the
downstream check fires. Falls back to whichever branch resolved
when neither is sensitive.
24 new regression tests cover the glob class (10 blocked, 6 allowed)
and ternary (6 blocked, 2 allowed).
