The discipline first

Rigorous systems analysis is a documented practice you can do by hand: frame the question, type every connection, source every claim, attack the model, then decide. Drawing the model is the cheap half. Keeping it true is the expensive half: finding the sources, arguing the numbers, chasing the units, and re-testing when the world moves.

That is the work SOSX carries, with more than fifty specialised AI agents, so every value keeps its source and its confidence. And the decision stays with you, with the reasoning kept beside it.
