Research prototypes and engineering debt: Lab, Review, and Transfer
This is 55AA-019, week 13, session 2. It focuses on "Research prototypes and engineering debt" and turns the weekly plan into discussable, practicable, and reviewable class artifacts.
Learning Objectives
- Explain where "Research prototypes and engineering debt" fits in this course and what core problem it addresses.
- Analyze a case or system related to "Research prototypes and engineering debt" using today's method.
- Connect the session task to the course outcome: Extract problems, assumptions, methods, and evidence chains from papers.
- Complete the questions, notes, and synthesis required by workshop, exercise, and review.
Prerequisites
- At least one systems or security course.
- Have read the weekly task: Clean code, scripts, and reproduction instructions.
- Be able to record assumptions, evidence, risks, and questions to validate in class.
Preparation
- Open the 55AA-019 course repository, readings, and this week's task brief.
- Write two true/false claims or open questions about "Research prototypes and engineering debt" before class.
- Be ready to show questions, lab notes, or project fragments from the previous meeting.
Class Flow

review
Quickly review the concept framework and unresolved questions for "Research prototypes and engineering debt".
When judging "Research prototypes and engineering debt", what fact should be confirmed first?
Expected answer: First confirm the object, boundary, attacker or user capability, observable evidence, and evaluation criteria.
Follow-up: If that fact is not directly observable, what minimal experiment would you design?
Opening
Today's session focuses on "Research prototypes and engineering debt". We will not treat it as an isolated topic. We place it in the course workflow: define the object and boundary, gather evidence, and turn the result into engineering action.

Review
Return to the previous discussion. State one important conclusion in a sentence, then state one remaining uncertainty. We will carry those uncertainties into today's analysis.

demo
Demonstrate how to turn the method into reproducible steps or a project fragment.
Where is the weekly task "Clean code, scripts, and reproduction instructions." most likely to fail?
Expected answer: Common failures include unclear goals, insufficient evidence, unreproducible environment, and conclusions without process.
Follow-up: What checklist item would reveal this failure early?
Guided question
Here is the first judgment question: if we know only the conclusion but not the environment, inputs, or evidence, can that conclusion guide engineering decisions? Answer yes or no first, then name your assumptions.

Follow-up: What checklist item would reveal this failure early?
Explanation
For "Research prototypes and engineering debt", the key is not memorizing definitions but following an analysis order: define the object, list boundaries, state who can do what, find observable evidence, and turn the conclusion into a task or test.

Exchange results and check reproducibility, explanation quality, and missed risks.
What makes a lab result reviewable by someone else?
Expected answer: It needs environment, commands, inputs, outputs, failure conditions, screenshots or logs, and explanations for anomalous results.
Follow-up: How would you write this requirement into homework or project acceptance criteria?
Practice transition
Now apply that order to the weekly task: Clean code, scripts, and reproduction instructions. Do not write only the final answer; preserve how you ruled out alternatives.
