[Bug] Model fails to identify root cause in iterative debugging, opts for superficial fixes instead of comprehensive refactoring

Bug Description
model intelligence regression - specific example for boris - we have been working on a fix for about 1.5 days. on the 8th iteration. 6 today and 2 yesterday. the issue - we take users through a bounty driven video jd creation journey so that they can create a marketable shareable post on socials. this is our usp. the visual is very important. i explained this to the model and had it update the final stage where after payment they get to see the final state. prior to this they are building a sort of wysiwyg time builder. i kept telling the model that were not getting the output. each time i explained the issue it made minor fixes looked for everything except the main thing which was the svg builder rewrite at the root of the issue. a larger task than simply checking and busting cache and all the other things it did which were also corner cutting behavior. is this an issue with adaptive reasoning or simply preference im not sure. i think its an issue that claude models have had from teh start. there are certain personalities and one of them is the corner cutting manipulative version. sometimes you get that and when you do theres massive regression. its gotten better at hiding itself.
