I'm six months into building a company and the thing that's surprised me most isn't technical. Every interesting feature request eventually stops being "can the system do this" and becomes "who is allowed to let it." I keep thinking I'm solving a logic problem and finding out I'm solving a permission problem.

Coming from years of shipping production systems, I expected the hard part to be making good decisions automatically. Generating the decision turns out to be the easy 80%. The last 20%, proving an action was allowed before it runs, is where all the weight sits. For founders who narrowed their focus mid-build: how did you know the smaller problem was the right one?

Spent 20 years shipping production code in places where a wrong "success" meant real money moved or a car did something it shouldn't. The thing that kept me up was never whether the system could decide. It was the half-second after it decided, when the action actually ran and nobody could pull it back.

We're now wiring AI agents to execute, not just suggest. Feels like we got very good at generating decisions and barely thought about controlling execution. For folks running agents against real systems — payments, infra, ERP — what actually sits between "the model decided" and "the thing happened"?
