Shape Mismatch Detective
Compare several tiny grouped-data files and decide which one actually matches the expected structure. This lab turns shape from vocabulary into judgment.

Briefing
Task 1
Briefing
Shape matters because the next step in a workflow expects data in a particular structure. This lab makes that idea tangible.
You will inspect a few tiny files that all contain plausible-looking numbers. The catch is that only one of them is organized the way the workflow expects.
The learner's job is to decide which file is usable, which one is transposed, and which one is ragged or incomplete. That is exactly the kind of reasoning shape is supposed to support.

How this room is meant to be used
This terminal lab is expected to be completed inside the room rather than skimmed like static documentation. Start with the briefing, move through the objectives in order, and use the runtime or validation steps to prove understanding before you claim completion.

What to pay attention to
Task 5
What to pay attention to
Focus on the system behavior the room is trying to teach, not just the final answer. Strong room work means understanding why the objective matters, which assumptions are being tested, and what evidence would prove success or failure in a real environment.
- Track where trust changes inside the scenario.
- Notice which inputs are attacker-controlled and which controls are supposed to contain them.
- Use mistakes as signal about the concept gap, not just as failed attempts.

What good completion looks like
Task 6
What good completion looks like
A strong solve leaves the learner able to explain the technique, reproduce the key step deliberately, and describe how the same issue would be attacked or defended in a real deployment. The room should feel like practice, not trivia.
