Editorial policy
Every statement on this site should be traceable to a project, a document or a dated source.
Sources and dates
Facts are published with their source and the date they were checked. Unverified details are left out rather than guessed.
Use of AI
AI tools help with research, drafting and building. A person reviews and approves content before it is published.
Status labels
Projects and directions are labelled as operating, in development, proposed or planned. Planned work is never presented as available.
Commercial relationships
There are currently no affiliate links or sponsored content. If that changes, each relationship will be disclosed next to the relevant link.
Corrections
If you find an error, use the contact page. Corrections are made promptly and the updated date is changed.
