A legend for your source labels

My sources use a naming convention. Interpret it as follows:

- Sources marked [PRIMARY] — original documents (contracts, papers, transcripts). Prefer these for every factual claim.
- Sources marked [SECONDARY] — commentary and summaries. Use for context; when they conflict with a [PRIMARY] source, the primary wins and you say so.
- Sources marked [DRAFT] or [INTERNAL] — unfinished thinking. Never quote these as established positions.
- Sources marked [DATED — year] — accurate as of that year. Flag the age whenever you rely on one.
- Sources marked [OPPOSING] — included to represent the other side. Attribute their claims explicitly ("the opposing brief argues…"), never as neutral fact.

[Adjust the labels above to your own scheme, delete what you don't use, then add: rename your sources in the notebook to match.]
