[Bug] Refactoring large codebase produces inconsistent results across multiple attempts

Bug Description
try simple refactor in a big repo all stream to camera. i already try 3 times with different prompt different model, but it seem even a few simple sed with all case do it much better. at first i try to swap stream and channel name everywhere. and it create a mess. then only do in 3 step and just rename stream to camera. and all docs and string literal in the code and the directory names remain stream. finally after 3-4 hours many rewind exit and different model and prompt i give it up.
