Learning objectives​

  • Explain Technical-Debt Ledger — Not Everything Gets Fixed as the disciplined conversion of design intent into working software with evidence, not just feature completion.
  • Use Technical-Debt Ledger — Not Everything Gets Fixed to reason about feedback loops, test confidence, quality boundaries, and the cost of weak implementation discipline in a capstone project.
  • Use clean-code, good-code-bad-code, refactoring, software-engineering-at-google to connect the learner page to code structure, verification strategy, and the practical mechanics of shipping a reliable implementation.

Prerequisites​

  • Comfort with the capstone domain, architecture direction, and the need to prove behavior through repeatable tests and evidence.
