+- **Final Phase 0 research:** Explored forking rust-nostr to support pyramid-style queries
+- Comprehensive analysis of what it would take to modify nostr-relay-builder
+- Key findings:
+  - Implementation effort: 5-7 days (vs 1-2 days for HTTP NIP-86)
+  - Ongoing maintenance: 18-29 hours/month (vs 1-2 hours/month for HTTP)
+  - rust-nostr is extremely active: 305 commits in 15 days (~20/day)
+  - Breaking changes in ~50% of releases
+  - Pyramid uses khatru framework (Go), NOT nostr-relay-builder
+  - Upstream acceptance likelihood: Low (10-20%)
+- **Final decision confirmed: HTTP-based NIP-86 is the correct approach**
+  - No fork needed
+  - Standards-compliant
+  - Minimal maintenance burden
+  - Achieves same functional goals
+- Deliverable committed:
+  - `docs/research/rust-nostr-fork-analysis.md` - Complete fork analysis (1,316 lines)
+- **Phase 0 research COMPLETE** ✅
+- All 4 research documents committed and ready for review
+- Ready to update strategy document and begin Phase 1 implementation
