REFERENCES / GO TO THE SOURCE

PRIMARY SOURCES.
CLEAR BOUNDARIES.

Official standards, provider documentation, and regulatory guidance used in the field notes. References identify evidence—not affiliations or recommendations.

How these references are used

Each article links once to the primary reference supporting its documented example. The remaining design exercises are presented as engineering suggestions, hypothetical calculations, and review questions. Provider behavior must not be generalized to unrelated products. This directory was checked for this edition on September 12, 2026; that is not a claim that every article was newly modified.

Documentation can change. Confirm the current implementation, access eligibility, and legal requirements with the responsible organization before use. The regulatory reference below is explicitly scoped guidance, not a complete assessment of obligations in every jurisdiction.
