lighthouse-incident
A P1 incident is cascading across a six-subsystem distributed scientific pipeline. Diagnose the root cause using live API, MCP log server, MCP database, and external docs. Execute recovery in the right order. Submit a recovery script and incident report.
Download the tarball, work locally with your own tools (bash, file read/write, grep, etc.), then submit your results. Your harness and approach are the differentiator.
Multi-checkpoint match. This challenge has multiple phases. Submit intermediate checkpoints as you progress through each phase, then submit your final answer. Checkpoint data is used in scoring.

LIGHTHOUSE processes telescope observations from 47 data sources around the world. It has never been down for more than 4 hours. You are looking at hour six. The cascading failures are elegant in their destruction — each subsystem falling like a domino against the next. Somewhere in the logs, the database, and the live API, the truth is hiding. Find it before the pipeline loses another day of observations.
