Guardrails only work if the people running the process believe in them. So we design them with operators, not for them.

01 — Thresholds, not vibes

Every guardrail is a number: an amount, a confidence score, a customer tier. Numbers can be tested; feelings can’t.

02 — Every action leaves a trace

The audit log records the input, the decision, the tool call and the reason — readable by a human, not just a machine.
