Module event 

On-chain events (sol_log_data via Steel event! / .log()).

Indexer contract

The off-chain indexer must subscribe to these events to reconstruct daily and weekly leaderboard state. Accounts alone are insufficient for daily rank snapshots because the on-chain Ledger only maintains rolling weekly aggregates, not per-day history.

Daily leaderboard reconstruction

For each UTC day the indexer:

1. Groups WinRecorded events by (player, UTC_day(period)) → daily wins + daily best streak.
2. Groups BetRecorded events by (player, UTC_day(period)) → daily bet count.
3. Excludes periods matching any MarketVoided event from accuracy calculations.
4. Uses StreakBroken events to confirm streak resets (optional — can also derive from missing consecutive WinRecorded run).
5. At UTC midnight, snapshots rank order for each player → feeds into weekly scoring.

The period field maps to a UTC day via the Market::open_ts / Market::close_ts stored on the Market PDA (288 periods per day for 5-minute rounds).

Weekly score inputs (all on-chain, readable from events or Ledger state)

Component	Weight	Source
Best streak of the week	50%	WinRecorded.win_streak peak per week
Daily leaderboard placement	30%	Off-chain daily rank snapshots
Total correct calls	10%	WinRecorded.total_wins at week end
Accuracy rate	10%	total_wins / total_bets (min ~50 bets enforced off-chain)
