⚙️ Implementation Guide

1. Collect Events

// Scan events/ directory
const events = fs.readdirSync('events/')
  .filter(f => f.endsWith('.json'))
  .map(f => JSON.parse(fs.readFileSync(`events/${f}`)));

2. Classify by Priority

const urgent = events.filter(e => e.priority === 'urgent');
const important = events.filter(e => e.priority === 'important');
const info = events.filter(e => e.priority === 'info');

3. Duplicate Check

const sent = loadSentHistory(today);
const newEvents = events.filter(e => 
  !sent.notifications.some(n => n.id === e.id)
);

4. Deliver

// urgent → Immediate Discord DM
if (urgent.length > 0) {
  await sendDiscordDM(urgent);
}

// important → Add to heartbeat queue
if (important.length > 0) {
  await addToHeartbeatQueue(important);
}

// info → Add to daily-report queue
if (info.length > 0) {
  await addToDailyReportQueue(info);
}

5. Save History

saveSentHistory(today, newlySentNotifications);
