Dataset changelog
Harpd publishes one immutable snapshot per closed calendar month. This page reports what changed between consecutive snapshots. Every row is computed by diffing two snapshot files — nothing on this page is written by hand.
Immutable. A published snapshot is never rewritten. If Harpd has to correct a figure, the correction ships as a new snapshot plus an entry here — the old file keeps saying what it said.
Computed, not authored. The changelog has no editor. An entry omits additions and removals when no previous snapshot exists, because a missing baseline is not evidence that nothing changed.
Rank Points are promotional placement. A change in rank or Rank Points reflects Credits spent on the board, not an editorial quality judgement. See the methodology.
Snapshots
Each snapshot is a frozen file. Fetch it directly, or read the index at/data/rank/snapshots.json.
/data/rank/latest.jsonresolves to the newest closed snapshot
Changes by snapshot
No snapshot transitions have been computed yet. Harpd publishes a snapshot once a calendar month closes with published ranking data — until two such months exist, there is nothing honest to diff.
