+
+---
+
+## 📋 Summary
+
+This action plan covers:

+# Commit with clear message
+git commit -m "docs: archive completed phase documents and future planning roadmaps
+
+- Moved 22 documents to docs/archived/ (planning & phases)
+- Preserves git history with git mv
+- Phase 1-10 are 100% complete, these are historical records
+- Roadmap v2.0 documents are future planning, not current TODOs
+
+Related: Documentation audit DOCUMENTATION_AUDIT_2026.md"
+```
+
+**Day 3: Delete Redundant Documents (5 files)**
+
+```bash
+# Delete duplicate/obsolete files
+git rm docs/scdb/IMPLEMENTATION_STATUS.md  # Superseded by PROJECT_STATUS.md
+git rm docs/graphrag/TEST_EXECUTION_REPORT.md  # Temporary test output
+git rm docs/proposals/ADD_IN_PATTERN_SUMMARY.md  # Implementation detail
+git rm docs/proposals/VISUAL_SUMMARY.md  # Duplicate of README
+git rm docs/proposals/QUICK_REFERENCE.md  # Duplicate of main docs
+
+git commit -m "docs: remove 5 redundant/obsolete documents
+
+- IMPLEMENTATION_STATUS.md → use PROJECT_STATUS.md instead
+- Removed temporary test reports and duplicate content
+- All information preserved in canonical locations"
+```
+
+**Day 4-5: Update Key Documents**
+
+Files to update:
+1. `README.md` - Add server section, clarify Phase 9/10 complete
+2. `docs/PROJECT_STATUS.md` - Mark all phases 100%, add server planning
+3. `docs/INDEX.md` - Add server docs section, update feature matrix link
+4. `docs/analytics/README.md` - Mark Phase 9 100% complete (not 29%)

+4. **Create feature matrix** - Clear table of implemented vs planned
+
+### For Server Implementation (Start Week 4)
+
+1. **Review server plan** - `docs/server/IMPLEMENTATION_PLAN.md`
+2. **Create project skeleton** - 5 new .csproj files

+
+---
+
+## 📝 Questions to Answer
+
+1. **Server Protocols**: Implement all 3 (binary/HTTP/gRPC) in v1.5.0 or start with binary only?
+   - **Recommendation**: Binary + HTTP in v1.5.0, gRPC in v1.6.0
+
+2. **Authentication**: JWT default or certificate-based?
+   - **Recommendation**: JWT for HTTP, certificate for binary
+
+3. **Licensing**: Server requires separate license?
+   - **Recommendation**: Keep MIT for all (open-source)
+
+4. **Release Schedule**: v1.5.0 target date?
+   - **Recommendation**: Q2 2026 (14 weeks from now = end of April 2026)
