Judge whether a service level objective can actually be observed, before any mea
Judge whether a service level objective can actually be observed, before any measurement exists. The central check: at the expected event volume, one failure may already exceed the whole budget, so the objective is met with zero failures and breached by one and measures nothing in between. Also reports a budget of fewer than ten events, where chance dominates service quality, and a burn-rate alert whose own window is longer than the time that burn takes to exhaust the budget.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
