 - Deliverable: `docs/research/nip-86-implementation-options.md` committed
 - Next: Phase 0 Track B (nostr-relay-builder user storage events) - deferred for now

+- **Critical architectural decision:** Identified gap in design - NIP-86 is for actions, not queries
+- Researched how to return sensitive data to authenticated users (admins and regular users)
+- Launched 3 parallel research subagents:
+  1. NIP-86 query response patterns in spec and rust-nostr
+  2. Pyramid relay admin patterns (real-world implementation)
+  3. Feasibility of pyramid-style approach with rust-nostr
+- Key findings from research:
+  - ✅ NIP-86 spec uses HTTP POST/response (NOT Nostr events for query results)
+  - ✅ Pyramid uses ephemeral events to specific WebSocket connections for queries
+  - ❌ nostr-relay-builder does NOT support connection-specific messaging
+  - ❌ Pyramid approach requires forking nostr-relay-builder or custom WebSocket handler
+- **Decision: Use HTTP-based NIP-86 for all queries and actions**
+  - Queries: HTTP GET/POST with NIP-98 auth → JSON response
+  - Actions: HTTP POST with NIP-98 auth → JSON response
+  - Both admin and user queries use same pattern
+  - Simpler, standard, no framework modifications needed
+- Deliverables committed:
+  - `docs/research/nip-86-query-responses.md` - NIP-86 spec analysis
+  - `docs/research/pyramid-admin-patterns.md` - Pyramid implementation study
+  - `docs/research/pyramid-style-queries-design.md` - Feasibility analysis for rust-nostr
+- **Next:** Update strategy document to reflect HTTP-based approach for queries
+- Phase 0 research complete, ready to finalize architecture and proceed to Phase 1
