Checkpoint 1

Separate the recorded fields from interpretation

Begin with the catalogue layer. Retain the stable record ID and read the raw date, place, names, and classification fields as recorded values—not as conclusions.

Checkpoint 2

Check how the point reached the map

A precise-looking marker can still rest on coarse or provisional geography. Check the coordinate tier, precision, source, and stated uncertainty before drawing spatial conclusions.

Checkpoint 3

Follow the APRO publication route

Open the reviewed archive route and note what the precision badge actually promises. A highlighted viewer page is a finding aid; verify the scan before quoting or attributing a claim.

Checkpoint 4

Compare an independent publication family

Now follow a Data-Net route for the same catalogue record. Distinct publication families are useful for source comparison, but source counts do not by themselves establish independence or truth.

Checkpoint 5

Carry the method into comparison

Add three reviewed dossiers to the research workspace. Compare dates, locations, source families, link counts, and evidence-status labels while leaving missing fields visible.

Interpretation boundary

The trail organizes checks; it does not decide the case.

Source-family counts describe archive coverage. Link-precision labels describe routing confidence. Neither substitutes for reading the scan, identifying dependence between publications, or evaluating a claim.
