NimbusStack Incident: The Poisoned Pipeline

Something went wrong inside NimbusStack production was touched, but nobody admits to touching it. You are brought in as the investigator. This is one continuous breach told across five stages, not five isolated puzzles. What you find in one stage opens the next, and the final vault cannot be opened without proof you completed the entire chain. Read everything the platform gives you its responses, its errors, its documentation. Players who read slowly finish faster than players who move fast. The server is hosted on nimbus.prod.local
