Activity (30-day lookback)
One cell per day, oldest on the left. Filled cells indicate the source delivered new content that day. Lighter cells mean the pipeline checked but the upstream content was unchanged.
Reference feeds
NOAA buoy and tide-station data are shown on the dashboard view only. They are not part of the daily risk-score pipeline, so their fetch cadence is not tracked here.
Sample dates from the underlying datasets can be older than "last fetched". For example, an upstream agency may publish a PDF on Tuesday that only contains samples through the previous Wednesday. This page reflects when our pipeline saw a content change, not when the agency actually collected the sample.
