Editorial policy

Show the method. Label the uncertainty.

Evidence standard

Product specifications should link to manufacturer documentation. Prices, fees, exchange rates and program terms require a review date. Firsthand measurements must identify the printer, material, method and sample limitations.

AI assistance

AI may assist research, drafting, coding and quality checks. It is not treated as a factual source. Every page intended for public release requires source verification, calculator testing and editorial review.

Commercial content

Affiliate eligibility or commission must not determine conclusions. Alternatives, assumptions and meaningful disadvantages should be stated. Sponsored placement, if ever accepted, must be visibly labeled.

Corrections

Material errors should be corrected promptly with the review date updated. Send corrections to [email protected].
