# Sources

This pack paraphrases recurring ideas from Robert C. Martin's broader
engineering work. It does not reproduce source prose, and the sources are
inspiration rather than repository authority.

- Robert C. Martin, *Agile Software Development: Principles, Patterns, and
  Practices* (2002): SOLID principles, dependency management, and iterative
  design.
- Robert C. Martin, *Clean Code* (2008): readability, naming, functions,
  duplication, and tests.
- Robert C. Martin, *The Clean Coder* (2011): professional commitments,
  uncertainty, practice, and quality responsibility.
- Robert C. Martin, *Clean Architecture* (2017): policy/detail boundaries,
  dependency direction, and architectural trade-offs.
- Robert C. Martin, *Clean Agile* (2019): feedback, tests, refactoring, and
  disciplined incremental delivery.

Use repository evidence and current domain constraints to decide whether any
paraphrased heuristic applies.
