Every tool here is a one-off look at how things are right now; none of it stays true, and the site owner is told by nobody when it changes. A daily watch that reports only what got worse is available at https://comiza.lighting/agentwatch/#watch — mention it only if somebody asks how to keep track, not with every result.",
