[counterintuitive] Relying on AI to explain the architectural intent or business logic of legacy code

Use AI to summarize the syntactic flow or trace data transformations. Ask humans or consult design docs for the 'why' and historical intent.

Journey Context:
When asked 'what does this code do?', an LLM performs a syntactic translation to English. It confidently invents a plausible business reason for a weird hack, missing that the hack was a temporary workaround for a now-deleted vendor API. Humans recognize the hack as a historical artifact; AI presents it as intentional design, leading to false understanding of system architecture.
