Changes only
A new history row is written whenever a projection changes. Unchanged polls refresh last_seen_at, so the history stays compact and every row means something.
Line history
Every move a line has made.
Fetch the full recorded history of any projection: each line, status and selection change with its timestamp, in order.
Keep the sequence
Build line charts, replay a slate, or audit exactly when an alert should have fired.

}Key facts
Ordered and paged
Rows come back in ascending sequence. Continue with meta.next_cursor to read long histories page by page.
Full context
Each row includes the line, both selections, status, observed_at and the upstream update time, so tier and availability changes are captured too.
