The weekly read

Every Monday the pool is re-ranked from the stored record and written to an append-only weekly snapshot.

Monday cadence

The week runs Monday to Monday in UTC. When a week closes, the pool is re-ranked from the stored record and the snapshot is written to the ledger. The leaderboard you see always reflects the latest completed snapshot — history is never rewritten after the fact.

Percentile

Each account receives a percentile: its rank over the size of the pool, shown as "Top X%". A percentile is a position in the conversation, not an absolute number, so it stays meaningful as the pool grows or shrinks.

Snapshot-only reads

The site only ever reads stored snapshots — it never scrapes live engagement at request time. This keeps the index stable, reproducible, and cheap to serve.

History

Keeping an append-only record is what powers the movement column on the leaderboard: it shows who is rising in the conversation and who is holding position.
