Target time
18m
During an outage you need dashboards, logs, and a scratch shell visible without losing context. You are working inside a high-speed terminal dojo, and the arena only clears when the result is safe, deterministic, and explainable.
Learning objective
Learn to apply session layout, pane naming, logs, tests, and command ergonomics in a high-speed terminal dojo while explaining the invariant, safety constraints, and hidden edge cases.
Mission order
Commands tail logs, run health checks, watch queue depth, and keep notes. Implement the direct solution first, then document the one edge case that can break it. Submit the solution plus enough reasoning to pass hidden edge cases.Visible checks
uses safe command composition
Expected: deterministic command sequence
handles ordinary filenames
Expected: stable output
Clear requirements
- Demonstrates session layout, pane naming, logs, tests, and command ergonomics
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids destructive host commands
Secure validation contract
Judge type
LINUX
Complexity target
Linear scan over simulated files/log rows with deterministic output
Simulated lab
3 files/directories, allowed commands: awk, cat, cut, du, df, find, grep, head

Terminal lab

Test Results
Run the visible checks when your first pass is ready.
Clear Protocol
1Read the scenario and restate the expected output shape.
2Run visible checks before chasing hidden edge cases.
3Use Genie for one nudge if stuck, then explain the invariant.
4Submit only when the result is deterministic and safe.
