Method and limits
Verify each source gzip SHA-256 and record count, then count public records and observation fields. Rank declared tags by distinct publisher_domain values. Code is published with the developer tools.
- Observation begins on the first available snapshot date, which may be mid-month.
- Listing totals change through discovery, failures, removals and duplicate consolidation. Net change does not equal newly created agents.
- A signature result, ownership claim and read-only protocol response are separate observations, not certification.
- Capability tests, where opted in, are separate from the read-only protocol response counts here.
