Sources and attribution
We prefer standards, issuer resources and official documentation for technical claims. Articles cite the relevant primary source. Articles are credited to the Editorial Team. This organizational byline does not imply professional certification.
Separate facts, models and opinions
A published specification is a source. An evidence ladder is our explanatory model. A service-selection recommendation is judgment. We label these distinctions and do not imply that a model is an official standard.
Research and service comparisons
Testing reports state the method, inputs, expected results and limitations. Service profiles distinguish provider statements from independently supported findings. A claim that cannot be verified stays unresolved.
Review and corrections
Published content has a review date only when it has actually been reviewed. A material correction changes the affected claim and records the change in context. See the corrections policy for how to submit an issue.
Independent educational scope
Commercial intent does not justify unsupported claims or instructions that facilitate document fraud. Educational examples must stay fictional and may not reproduce realistic government identification.
