Recent Decisions
2025-10-11: RFC-0001 - Foundation Model Strategy - ✅ Adopted hybrid approach (Option 3) - Launch with Sentence-BERT + simple model (Weeks 1-3) - Train custom model in parallel (Weeks 2-6) - Deploy custom when it beats baseline
2025-10-11: ADR-0002 - Free Tier First - ✅ Committed to $0 infrastructure cost for MVP - Start with free tier, upgrade based on revenue - Target: < $0.05/user/month at scale
2025-10-11: ADR-0003 - Cloudflare-Native Stack - ✅ Cloudflare Workers for compute - Qdrant for vector database - Supabase for PostgreSQL - Fly.io for Python ML
Risks & Blockers
Current Risks
🟡 Medium Risk: Custom Model Quality - Risk: Custom foundation model may not outperform simple model - Mitigation: A/B test before full deployment, keep simple model as fallback - Owner: TBD
🟡 Medium Risk: Free Tier Limits - Risk: May hit Qdrant 1GB limit sooner than expected - Mitigation: Monitor usage, optimize embeddings, plan upgrade at 1K users - Owner: TBD
No Current Blockers 🎉
