Observability: The Prefect UI & Run States

Day 67 of 100 Days of MLOps. Every flow you've run has been recorded — today you see where, and learn to read it. Start the Prefect dashboard, understand the run states (Completed, Failed, Retrying, Cached, Crashed) that tell you what happened at a glance, and drill into any run's logs and parameters. When a pipeline runs unattended at 2am, this is how you know exactly what it did. Observability is what turns orchestration from a black box into a system you can trust. Runs 100% locally on any OS.
