Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: Improper reference counting (redundant Py_INCREF) and incomplete implementation of garbage collection hooks (tp_traverse, tp_clear) in the C extension lead to severe memory leaks and eventual application exhaustion during cyclic garbage collection.

Denial of Service: Accessing attributes on uninitialized Proxy objects leads to unhandled exceptions and crashes during attribute resolution. Ensuring safe attribute presence verification prior to extraction is critical to preventing runtime exceptions.
