Secondary source

Also called: secondary sources, summary, summaries, second-hand source

A description of the original material rather than the material itself, such as a summary, a README or a compaction note. It is cheap to load but always leaves things out and can go stale, so important decisions should be checked against the primary source.

For example: A handoff note says the payment bug is fixed, but the agent checks the code before telling the founder, because the note is only a secondary source.
