Recurring patterns

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

Denial of Service: NaN propagation in model operations leads to invalid floating-point results, causing out-of-bounds indexing on pre-computed sigmoid/log lookup tables and resulting in application crashes.

Denial of Service: Failure to decrement Python object reference counts when converting strings in pybind functions causes a cumulative memory leak, eventually leading to process exhaustion.
