…usResearch#77780) os.open() raises ValueError when the path contains an embedded NUL byte, but _read_referenced_script only caught OSError. Add ValueError to the except clause to prevent the guard from crashing.

Fixes #77780
_read_referenced_script()incron/lifecycle_guard.pycallsos.open(path, flags)but only catchesOSError. When the path contains an embedded NUL byte (from binary content tokenized as a script path),os.open()raisesValueError: embedded null bytewhich propagates uncaught throughcontains_gateway_lifecycle_command_or_referenced_script→terminal_tool, blocking all subsequent terminal commands.The caller at line 318 already handles
ValueErrorforscript_path.resolve(), but theos.open()call at line 260 was missed.Fix
Add
ValueErrorto theexceptclause atlifecycle_guard.py:261, matching the existing pattern at line 318.
