Primary sources first
l0g gives priority to official datasets, filings, central banks, regulators and primary documents. Aggregators and press coverage are useful, but they are not a substitute for the underlying source when a claim depends on a number, a rule or a filing.

How l0g uses secondary sources
Reference financial press is used for context, chronology, interviews and market color. When a secondary source reports a specific number or rule, l0g tries to trace it back to the primary release, filing, table or statute.
How uncertainty is handled
Estimates, model outputs and unofficial datasets are useful only when labeled as such. l0g avoids presenting them as observed facts. A good source is not only reputable; it must also be the right source for the claim being made.
