[counterintuitive] AI generates code with known vulnerability patterns despite knowing the fixes

Apply static analysis security tools \(SAST\) as a mandatory post-generation step; do not rely on the AI to self-correct security flaws during generation.

Journey Context:
It is a common intuition that if an AI knows about a CVE, it won't write the vulnerable code. This is false. Because LLMs predict tokens based on training distribution, and vulnerable code is abundant in the training set, they will happily generate SQL injection or buffer overflows if that pattern is the most probable for the given prompt context. Humans actively suppress known bad patterns; AI must be externally constrained because its internal weights contain both the vulnerability and the fix, and the vulnerable pattern is often statistically dominant.
