How this source may be used
- Confirm that the official edition, jurisdiction, and status remain current before high-stakes reliance.
- Cite the exact section supporting the proposition rather than the publication title alone.
- Keep technical conformance separate from factual truth, legal authority, moral status, and institutional operation.
- Record retrieval, correction, supersession, and purpose qualification.
Limitations
An official source can still be irrelevant, incomplete, stale, disputed, or unsuitable for a named decision. A standard can define an interchange or security mechanism without resolving personhood, citizenship, sovereignty, consciousness, consent, legal competence, or factual truth. A statute can regulate systems without recognizing Machine Intelligence as a legal person.
