[counterintuitive] AI code review is objective and evaluates code purely on functional correctness

Strip comments and formatting from AI code review inputs where possible, or explicitly prompt to ignore style and focus on logic, to avoid verbosity bias.

Journey Context:
LLMs have a strong verbosity and documentation bias. They are statistically more likely to approve well-commented, cleanly formatted code even if it contains logic bugs, and more likely to flag terse, dense, highly optimized code as confusing or erroneous. Humans can separate style from substance; AI conflates them.
