Be honest — when did your architecture diagram last match the code?

Every team I've been on has had "the diagram" somewhere — a Miro board, a Lucid file, a photo of a whiteboard — and on every team it was quietly wrong within a month or two. Nobody updates it, so eventually nobody trusts it, and new engineers just re-derive the system in their heads.

• How do you document your system's architecture today — and does it stay accurate?

• Have you just given up on diagrams and rely on reading the code?

• If a diagram could stay in sync automatically, what would it need to do for you to actually keep it around?

Not looking for validation — I want the honest version, including "diagrams are a waste of time." Curious what's worked and what hasn't for you.
