Workstream G: Implement AEG-X-009 P1-P6 (KRX/OpenDart/KIS API integration)
- P1: KRX OpenAPI service (indices, stocks, OHLCV data) - P2: OpenDart API service (company disclosures, quarterly financials) - P3: KIS API service (trading orders, portfolio holdings) - P4-P6: Daily scheduling, error classification, SLA tracking, LKG fallback - Schema: market_data schema with append-only import logs - Error handling: transient/permanent classification + exponential backoff - Idempotency: correlation_id deduplication for safe replay - Services: 3 independent data services with caching, retry logic - Handler: Centralized import orchestration with logging - Job: Hangfire daily scheduler (q-evaluation queue, 16:30-20:30 KST window) - Tests: Unit & integration scenarios for import execution - AGENTS.md v16.0 13/13 compliance ✅ Closes workstream G (Phase 2 preparation).
