Source and fact-checking policy

Evidence hierarchy

1. Primary authority. Legislation, government guidance, official standards documentation, scheme-owner documentation and manufacturer technical specifications.
2. Primary research. Relevant peer-reviewed studies, systematic reviews and datasets with a method that can be inspected.
3. Professional body. Guidance from an organisation with a clear remit and accountable authorship.
4. Transparent industry evidence. Reports with identifiable funding, sample and methodology.
5. Secondary explanation. Reputable editorial sources used for context, never to override the primary material.

Fact-checking rules

• Search snippets and AI outputs are discovery aids, not final evidence.
• Every important statistic needs a source, population and date.
• Legal or technical guidance is labelled by jurisdiction and checked for current editions or transitional provisions.
• Conflicting credible sources are described rather than averaged into false certainty.
• Experience, inference and recommendation are separated from documented fact.
• No quote, DOI, credential, test result, case study or bibliographic item is created when the evidence is absent.

Source notes on each guide

Primary sources are linked close to the reference section, with an access date and a short explanation of what they support. Readers should be able to distinguish the official material from Roomology's original method. External links open as ordinary web links and are not affiliate redirects.

First-hand evidence

A future article may use site observations, photographs, interviews, tests or case studies only when the contributor supplies them and the method, date, conditions, consent and limits can be described. Synthetic imagery may illustrate a design concept but will not be presented as a real project, person, property or test.

When a page is held

If the available material supports only a generic summary, the page remains outside the public site. The editorial record identifies the missing source, expert input, original media or first-hand evidence required before work resumes.
