This is a timeline of URSY feed observations and grouping corrections. It is not necessarily the chronology of the real-world event. Historical stories may have been grouped after their original first-seen time.
URSY groups publisher-feed metadata. It does not fetch or republish full article bodies. Read the original reporting through the publisher links above. Text and image rights stay with the publishers; API access grants no republication rights.
The label is a deterministically selected publisher headline. Group membership can be corrected, and changes remain visible in the observation log. The archive retains up to 400 items per configured source feed; a publisher may have several feeds; older member text may no longer be available.
