Kumasan Event Monitor

Next.js + Vercel Cron app for tracking newly added ticket events and notifying Telegram.

Phase 1 scope

Twice-daily Vercel cron trigger
Per-source parser abstraction
Normalized event persistence in Postgres
Diff detection for newly seen events
Telegram notification delivery

Current targets

Parsers emit a unified event schema, and the monitor persists, diffs, and notifies via Telegram.

Unified event sample

{
  "sourceKey": "kham",
  "title": "Sample Event A",
  "detailUrl": "https://example.com/a",
  "eventDateText": "2026/05/03(日)"
}

Telegram is now the only notification channel.
