## Open Questions & Decisions Needed

### Architecture Decisions

1. **Self-Hosted vs Cloud:** What's the balance for infrastructure ownership?
   - **Options:** Full self-hosted (OSS stack) vs hybrid (OSS core + commercial integrations)
   - **Impact:** Cost, maintenance, data sovereignty

2. **Metadata Store:** DataHub vs OpenMetadata vs custom?
   - **Recommendation:** DataHub primary + OpenMetadata for lineage viz
   - **Rationale:** Best API, LinkedIn backing, proven at scale

3. **Event Bus:** NATS vs Kafka vs Redis Streams?
   - **Recommendation:** NATS JetStream (lightweight, persistent)
   - **Rationale:** Simpler than Kafka, more features than Redis

4. **Real-Time Sync:** CRDT vs OT vs polling?
   - **Recommendation:** Hybrid (CRDT for tasks, OT for docs)
   - **Rationale:** Best fit per use case

### Integration Priorities

5. **Which PM tool first?** ClickUp vs Asana?
   - **Recommendation:** ClickUp (better API flexibility)
   - **Fallback:** Asana (if enterprise procurement preferred)

6. **Observability: OSS only or add commercial APM?**
   - **Recommendation:** Start OSS, add Datadog if budget allows
   - **Rationale:** Prove value before cost commitment

7. **Documentation: MkDocs or Docusaurus?**
   - **Recommendation:** MkDocs (simpler, faster to implement)
   - **Alternative:** Docusaurus if React expertise available

### Deployment Decisions

8. **Container orchestration:** Kubernetes vs Docker Compose?
   - **Recommendation:** Docker Compose for MVP, K8s for scale
   - **Rationale:** Simplicity vs scalability trade-off

9. **Multi-region:** Single region vs global deployment?
   - **Recommendation:** Single region for MVP
   - **Future:** Multi-region if latency becomes issue

10. **Deployment strategy:** Blue/green vs rolling vs canary?
    - **Recommendation:** Rolling for services, blue/green for DB migrations
    - **Rationale:** Balance safety and simplicity
