Critical Path Summary

The minimum viable path to a working Intelligence Platform:

1. Platform Core (shared types, Location, Contact)
2. DMC Vertical (post-spike: enrichment, quality, extraction)
3. Dining Vertical (acquisition, schema, MCP tools)
4. MCP Server Production Transport (HTTP/SSE)
5. Crawler Framework Enhancements (incremental crawl)
6. Observability Pipeline (metrics, logging, alerts)
7. Data Quality Monitoring
8. Production Deployment

Estimated critical path: ~10-12 weeks if fully staffed and unblocked.

Risk Areas

Risk	Impact	Mitigation
Partner API access delays	High	Start with public sources, escalate API access
JS-rendered pages block extraction	Medium	Use Playwright for specific sources, or accept lower coverage
Data quality regressions	Medium	Implement quality monitoring early, alert on regressions
SQLite scaling limits	Low	Monitor growth, plan Postgres migration at 10x
Cross-vertical search complexity	Medium	Start with simple ranking, iterate based on agent feedback
OAuth requirements for Transportation	High	Start OAuth flows early, escalate partner conversations
