VKC Regulation / Knowledge Updater (P2)

Goal

Keep “규정/서류 요구사항/공식 공지” up-to-date as data, not code:

• fetch or ingest updates into snapshots
• detect changes
• require admin approval to activate
• feed active rulesets into visa assessment + doc templates

Core model (minimum)

• immigration_sources (allowlist)
• immigration_source_snapshots (hash + fetchedAt + raw text / attachment path)
• immigration_rulesets (structured JSON + version + status)

Admin workflow (required)

• sync job writes pending snapshots/rulesets
• admin reviews diffs and activates the new version

Implementation notes (practical)

• Treat “no official API” sources as best-effort:
  • low frequency + caching + allowlist
  • immediate fallback to manual admin upload if unstable
• Scheduler: external cron hits /api/admin/immigration/sync (authenticated)

STEP3 official sources (SoT)

• Source list (A/B/C) and update cadence: docs/STEP3_SOT_RESOURCES.md
