Coulson is a robot

[kathrum.livejournal.com]

I'm having a hard time trying to find a fic that I never bookmarked for some reason. I remember that it takes place in the past when it is revealed that Coulson is being built by Stark as a project for the military. The project gets shut down, but Couslon is smuggled out so he is not destroyed. It ends with the team discovering the truth because he is injured so much he shuts down for a while while on a mission. Any help finding this would be very much appreciated!
