Missing prerequisites: python-easy-dataclass-parser

A webhook consumer needs to turn raw dictionaries into validated event objects. You are working inside a Python service repository, and the arena only clears when the result is safe, deterministic, and explainable.

Learning objective

Learn to apply dataclasses, validation, and structured parsing in a Python service repository while explaining the invariant, safety constraints, and hidden edge cases.

Mission order

Events include id, type, created_at, actor, and optional payload fields. Prove your approach, handle adversarial inputs, and leave the solution maintainable. Submit the solution plus enough reasoning to pass hidden edge cases.

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.

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.
