Target time
15m
A CLI command started failing sometime in the last 80 commits. You are working inside a collaborative Git repository, and the arena only clears when the result is safe, deterministic, and explainable.
Learning objective
Learn to apply git bisect, reproducible tests, and commit isolation in a collaborative Git repository while explaining the invariant, safety constraints, and hidden edge cases.
Mission order
A test command exits 0 for good commits and 1 for bad commits. 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 git bisect, reproducible tests, and commit isolation
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution

Complexity target
Command sequence preserves work, history intent, and verification signal
Git final state
Repository state demonstrates git bisect, reproducible tests, and commit isolation and includes verification notes.

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.
