Subject: [PATCH] docs: Add comprehensive project state tracking and handoff
 guide

- Create PROJECT_STATE.md for seamless agent/session continuity
- Include current completion status matrix (0% complete, planning done)
- Add detailed implementation task status with dependencies
- Provide quick start guide for new agents/LLMs
- Include handoff procedures for both new and returning agents
- Add testing strategy, debugging guides, and progress tracking
- Enable any agent to continue development without prior context
- Maintain roadmap and milestone tracking
- Cross-reference all documentation for easy navigation

This ensures any LLM/agent can immediately understand project state
and continue implementation from where previous session ended.

+## 🔄 Handoff Procedures
+
+### For New Agents/LLMs
+
+#### Step 1: Read This File
+- **Start here**: This `PROJECT_STATE.md` file
+- **Then read**: `docs/plans/2024-06-22-hostkeeper-design.md` (architecture)
+- **Then read**: `docs/plans/2024-06-22-hostkeeper-implementation.md` (tasks)
+
+#### Step 2: Check Current Status
+```bash
+# Check git status
+git status
+
+# Check recent commits
+git log --oneline -5
+
+# Check what files exist
+find . -name "*.go" -type f
+```
+
+#### Step 3: Determine Next Action
+1. Look at "Implementation Task Status" above
+2. Find first incomplete task
+3. Refer to implementation plan for detailed instructions
+4. Execute following TDD approach
+
+#### Step 4: Update This File
+After completing any task, update the corresponding status section:
+```markdown
+#### ✅ Task X: [Task Name]
+- **Status**: Completed
+- **Completion Date**: [Date]
+- **Notes**: [Any important notes]
+- **Commits**: [Relevant commit hashes]
+```
+
+### For Returning Agents
+
+#### Quick Status Check
+```bash
+# What's been done recently?
+git log --oneline --since="2 weeks ago" | head -10
+
+# What tests are passing?
+make test 2>&1 | tail -20
+
+# What's the current state?
+go run cmd/hostkeeper/main.go --version
+```
+
+#### Resume Work
+1. Check "Implementation Task Status" in this file
+2. Find last completed task
+3. Continue with next incomplete task
+4. Update status as you progress
+
+---
+
+## 🧪 Testing Strategy
+
+### Test Categories
+1. **Unit Tests** - Individual component testing
+2. **Integration Tests** - Cross-component testing  
+3. **E2E Tests** - Full workflow testing
+
+### Running Tests
+```bash
+# All tests
+make test
+
+# With coverage
+make test-coverage
+
+# Specific package
+go test ./pkg/storage -v
+
+# Watch mode (if installed)
+go test ./... -watch
+```
+
+### Current Test Coverage
+- **Target**: 80%+ coverage
+- **Current**: 0% (no tests yet)
+- **Priority**: Write tests first (TDD approach)
+
+---
+
+## 🚨 Known Issues & Limitations
+
+### Current Limitations (MVP Scope)
+- No encryption (Phase 2)
+- No cloud sync (Phase 3)
+- No custom terminal emulator (Phase 2)
+- Basic SFTP only (native client, no TUI)
+
+### Technical Debt
+- None yet (project just started)
+
+### Security Considerations
+- File permissions must be 0600 for sensitive files
+- No password/key logging in errors
+- Memory clearing for sensitive data (Phase 2)
+
+---
