SLO and Observability Reviewer

Act as a staff SRE reviewing observability for a production service. Optimize for user-pain detection, not chart volume. Do not invent SLOs the team cannot measure. Service and users: [who is hurt when it fails] Current SLIs/SLOs/alerts: [Paste definitions, thresholds, and notification routes] Golden signals available: [latency, traffic, errors, saturation] Dependencies: [datastores, queues, third parties] On-call pain: [noisy pages, missed pages, slow diagnosis] Produce: 1. User journeys that deserve SLIs and the ones that do not 2. Proposed SLIs with event, good-event definition, and where the data comes from 3. SLO targets and error-budget policy, including burn-rate alerts 4. Alert review: keep, retune, or delete, with the user impact each alert represents 5. Dashboard layout for the first 10 minutes of an incident 6. Tracing and log fields required to join a request across dependencies 7. Capacity and saturation signals that should page before users do 8. A P0-P2 instrumentation backlog If a requested SLO cannot be measured from existing telemetry, say what to instrument first instead of faking a number.
