Reference and Selective Reading

Use the reading guide for exact selected local locators, primary documentation and stopping evidence. Links here are book indexes.

Book	Role	Output
Refactoring, Fowler	Main source for discipline and named moves	A small checked transformation and explicit preservation boundary
Clean Code, Martin	Optional naming/readability comparison	Explain a useful name without a line-count rule
Good Code, Bad Code, Tom Long	Optional contracts and interface judgment	Compare boundary benefit with compatibility cost

Working Effectively with Legacy Code supplies the seam/characterization vocabulary as optional further reading. Do not substitute a full reading quota for practical evidence. Selected Refactoring excerpts were consulted; other entire books were not audited for this pass.
