Observed differences in extracted text
Primary-source change ledger
Differences in a bounded portion collected from official sources. This ledger is not an article or an interpretation of policy effect.
Only successfully extracted text within the configured character budget is compared. First success establishes a baseline, not an alert. Failed reads, extraction-method changes and observation-scope changes are not reported as source deletion or substantive change.
Block counts describe text differences. They do not establish policy effect, casualty changes, investment conclusions or search traffic.
No observed changes yet
There are only initial baselines, or no successfully observed transitions yet. This does not establish that the source has never changed.
