> a structural map of the codebase to both constrain and validate what the model produces

I think this in apt and concise description of what this is trying to accomplish. I'm feeling like we had some really great gains in Model improvements both at the top end and the bottom over the last 6-7 months, but the next period is likely to be defined by harness improvements. I appreciate that your effort is being applied to this particular problem set because I think its far more fundamental to improving agentic performance in code bases than yet another memory framework.
