Primary documents
Official documentation, fee schedules, risk parameters, and named announcements are preferred where available.
Sources
Our pages should be checkable, not merely persuasive. We prefer primary documentation and label the difference between a source, a summary, and an editorial interpretation.
Dates and revisions
Every record should show when it was reviewed. When terms change, the source link—not an old summary—remains the reference.
Disclosure and corrections
Material commercial relationships should be disclosed on the relevant page. Factual errors should be corrected with a dated note.
