Harden protocol-based plugin typing
Hard Python arena: typing.Protocol, generics, and interface contracts
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: python-easy-typing-protocol
A CLI supports plugins and needs typed contracts without inheritance coupling. You are working inside a Python service repository, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply typing.Protocol, generics, and interface contracts in a Python service repository while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates typing.Protocol, generics, and interface contracts
- 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.
