Harden race condition repro
Hard Debugging arena: timing, shared state, and deterministic reproduction
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: debugging-easy-race-condition
Two concurrent saves sometimes overwrite the newest settings with stale data. You are working inside a debugging war room, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply timing, shared state, and deterministic reproduction in a debugging war room while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates timing, shared state, and deterministic reproduction
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.
