I don't think OP is looking for context from the AI model perspective but rather a process for maintaining a mental picture of the system architecture and managing complexity.
I'm not sure I've seen any good vendors but I remember seeing a reverse devops tool posted a few days ago that would reverse engineer your VMs into Ansible code. If that got extended to your entire environment, that would almost be an auto documenting process.
Context rots when it stays implicit. Make the system model an explicit artifact with fixed inputs and checkpoints, then update it on purpose. Otherwise you keep rebuilding the same picture from scratch.
