+
+## New Documents Created
+
+### CURRENT_STATUS.md
+
+**Purpose:** Single source of truth for project state
+
+**Content:**
+- Quick summary
+- Project structure
+- What works
+- What's next
+- Development workflow
+- Key technologies
+- Important gotchas
+- Recent milestones
+- Success metrics
+- Resources
+
+**Replaces:** Multiple status reports and session summaries
+
+---
+
+### AGENTS.md (Updated)
+
+**Purpose:** AI agent documentation guidelines
+
+**Already existed but now enforced:**
+- Documentation structure
+- Document lifecycle
+- Cleanup process
+- Common gotchas
+- Writing guidelines
+- AI agent responsibilities
+- Quality checklist
+
+---
+
+### docs/archive/README.md
+
+**Purpose:** Archive organization and usage guide
+
+**Content:**
+- Archive organization
+- Document index by date/topic
+- When to reference archives
+- Extracting learnings
+- Archive principles
+- Quick find by topic/date
+
+---
+
+## Benefits Achieved
+
+### 1. Clarity
+
+✅ **Easy to find current information**
+- `CURRENT_STATUS.md` - where we are
+- `README.md` - what the project is
+- `AGENTS.md` - how to document
+
+✅ **Easy to find historical information**
+- `docs/archive/` - organized by date
+- `docs/archive/README.md` - searchable index
+
+---
+
+### 2. Maintainability
+
+✅ **Clear document lifecycle**
+- Working docs in root
+- Permanent docs in docs/
+- Learnings extracted
+- Completed work archived
+
+✅ **No more sprawl**
+- Root directory stays clean
+- Archive grows but stays organized
+- Learnings get updated, not duplicated
+
+---
+
+### 3. Reusability
+
+✅ **Learnings are accessible**
+- Organized by topic, not session
+- Include code examples
+- Link to historical context
+- Living documents that evolve
+
+✅ **Patterns are documented**
+- Nix flake patterns
+- nostr-sdk patterns
+- grasp-audit patterns
+- Testing patterns
+
+---
+
+### 4. Onboarding
+
+✅ **New developers (human or AI) can:**
+1. Read `README.md` - understand project
+2. Read `CURRENT_STATUS.md` - know where we are
+3. Read `AGENTS.md` - learn documentation practices
+4. Read `docs/learnings/` - avoid known pitfalls
+5. Reference `docs/archive/` - understand history
+
+---
+
+## Cleanup Statistics
+
+### Before
+
+```
+Root directory:
+- 32 markdown files
+- Mix of status, reports, plans, summaries
+- Hard to find current information
+- Duplicate information
+- No clear organization
+
+docs/ directory:
+- 7 permanent docs
+- 0 learnings
+- 0 archived docs
+```
+
+### After
+
+```
+Root directory:
+- 3 markdown files (README, AGENTS, CURRENT_STATUS)
+- Clean and focused
+- Clear purpose for each file
+
+docs/ directory:
+- 7 permanent docs (unchanged)
+- 3 learnings (NEW)
+- 30 archived docs (NEW)
+- 1 archive index (NEW)
+```
+
+---
+
+## Document Count
+
+| Location | Count | Purpose |
+|----------|-------|---------|
+| Root | 3 | Essential project files |
+| docs/ | 7 | Permanent documentation |
+| docs/learnings/ | 3 | Reusable knowledge |
+| docs/archive/ | 30 | Historical records |
+| **Total** | **43** | **Well-organized docs** |
+
+---
+
+## Maintenance Going Forward
+
+### Daily Development
+
+**Create working docs in root:**
+- Session notes
+- Status updates
+- Temporary planning
+
+**Keep root clean:**
+- Max 5-10 working docs
+- Archive when complete
+- Extract learnings first
+
+---
+
+### Weekly Cleanup
+
+**Trigger:** Root has >10 markdown files
+
+**Process:**
+1. Review completed working docs
+2. Extract learnings to `docs/learnings/`
+3. Archive to `docs/archive/YYYY-MM-DD-topic.md`
+4. Delete obsolete duplicates
+5. Update `CURRENT_STATUS.md`
+6. Commit changes
+
+---
+
+### Guidelines
+
+**Follow `AGENTS.md` for:**
+- When to create new documents
+- Where to put documents
+- How to name documents
+- When to archive
+- How to extract learnings
+
+---
+
+## Commit Message
+
+```
+docs: major cleanup and reorganization
+
+- Archive 30 completed session documents to docs/archive/
+- Extract learnings to docs/learnings/ (nix-flakes, nostr-sdk, grasp-audit)
+- Create CURRENT_STATUS.md as single source of truth
+- Create docs/archive/README.md for archive organization
+- Clean root directory: 32 files → 3 files
+- Enforce AGENTS.md documentation guidelines
+
+Root directory now contains only:
+- README.md (project overview)
+- AGENTS.md (documentation guidelines)
+- CURRENT_STATUS.md (current state)
+
+All historical documents preserved in docs/archive/ with proper dating.
+All reusable knowledge extracted to docs/learnings/.
+
+Benefits:
+- Easy to find current information
+- Clear document lifecycle
+- No more documentation sprawl
+- Learnings are accessible and reusable
+- Better onboarding for new developers/agents
+```
+
+---
+
+## Verification
+
+```bash
+# Verify structure
+ls -la *.md
+# Should show: README.md, AGENTS.md, CURRENT_STATUS.md
+
+ls -la docs/learnings/
+# Should show: nix-flakes.md, nostr-sdk.md, grasp-audit.md
+
+ls -la docs/archive/ | wc -l
+# Should show: 31 (30 files + README.md)
+
+# Verify no broken links (manual check)
+grep -r "\.md" docs/ | grep -v ".git"
+```
+
+---
+
+## Next Steps
+
+1. ✅ Cleanup complete
+2. ✅ Learnings extracted
+3. ✅ Archive organized
+4. 🔜 Commit changes
+5. 🔜 Start NIP-01 relay implementation
+
+---
+
+**Cleanup completed:** November 4, 2025  
+**Files organized:** 43 total  
+**Root cleaned:** 32 → 3 files  
+**Status:** ✅ Ready for next phase
