Yet it still fumbles even when limiting context.

Asked it to spot check a simple rate limiter I wrote in TS. Super basic algorithm: let one action through every 250ms at least, sleeping if necessary. It found bogus errors in my code 3 times because it failed to see that I was using a mutex to prevent reentrancy. This was about 12 lines of code in total.

My rubber duck debugging session was insightful only because I had to reason through the lack of understanding on its part and argue with it.
