Alerts that resolve themselves, or page with a tested hypothesis
The agent never acts on a hunch. It tests the hypothesis on a copy first, and when it cannot fix the problem the human still starts ahead: the page arrives with the hypothesis and the evidence.
Requirement
Incidents where the first responder is an agent arriving with a hypothesis already tested, and alerts that resolve themselves.
Design choices
Triage is read-only (T0) and cheap, so it can run on every page.
Fixes run only through pre-approved runbooks and the gateway; a failed verify escalates, it does not retry blindly.
Auto-close requires the verify contract, not the absence of an alert.
Evidence and gap
Built in Hangar: HolmesGPT triage and Sloth-based SLOs. Proposal only: sandboxed hypothesis replay and runbook execution through the gateway.
