The second hash was a matter of expedience based on the incredibly limited amount of time I had to get a change done and in SCM. It fell deep into the land of "unforgiveable mess that I could be absolutely confident about, thereby making the business customer happy as a clam."

As my business customer is hands down the best one I've EVER had in my career I was able to have the "ok I can get this in for tomorrow. But that means that you get no changes next week while I fix what I had to do to do this" conversation with him. A condition which, along with the desperation on my face, compelled him to concede to.
