A minimal audit trail for public-source legal research

Why the trail matters

A useful public-source research note should allow another reviewer to understand what was checked, when, and why a conclusion remains tentative. That is especially important when a chart summarizes legal or business records.

The five fields to preserve

1. Question — the decision or hypothesis being examined.
2. Source — the original public page or record, not only a secondary summary.
3. Retrieval time — a public source can change after review.
4. Matching rule — how names, identifiers, and variants were treated.
5. Limitations — what the source cannot establish.

Treat trends as prompts, not conclusions

An increase in observed records can result from data coverage, a new classification method, a reporting delay, or an actual underlying change. Sampling source records before writing an interpretation reduces this risk.

Keep the communication proportionate

State what was observed, distinguish it from inference, and avoid claiming that an open-source result proves identity, risk, or legal status. That keeps the output useful for research and easier to audit later.
