Initial commit: Clean DSS implementation
Migrated from design-system-swarm with fresh git history.
Old project history preserved in /home/overbits/apps/design-system-swarm
Core components:
- MCP Server (Python FastAPI with mcp 1.23.1)
- Claude Plugin (agents, commands, skills, strategies, hooks, core)
- DSS Backend (dss-mvp1 - token translation, Figma sync)
- Admin UI (Node.js/React)
- Server (Node.js/Express)
- Storybook integration (dss-mvp1/.storybook)
Self-contained configuration:
- All paths relative or use DSS_BASE_PATH=/home/overbits/dss
- PYTHONPATH configured for dss-mvp1 and dss-claude-plugin
- .env file with all configuration
- Claude plugin uses ${CLAUDE_PLUGIN_ROOT} for portability
Migration completed: $(date)
🤖 Clean migration with full functionality preserved

# DSS Export/Import - Production Hardening Summary
|
||||
|
||||
## Status: ✅ PRODUCTION-READY (Hardened v1.0.1)
|
||||
|

Based on expert validation from **Gemini 3 Pro**, comprehensive security and reliability hardening has been implemented to address all critical production concerns before wider rollout.
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The DSS Export/Import system has been evolved from v1.0.0 (fully functional) to **v1.0.1 (production-hardened)** with:
|
||||
|
||||
- **6 new security/reliability modules** addressing Gemini's expert review findings
|
||||
- **Service layer architecture** for API integration with transaction safety
|
||||
- **Production readiness guide** with operational procedures
|
||||

|
||||
|
||||
## Production Deployment Steps
|
||||
|
||||
### Step 1: Code Review
|
||||
```
|
||||
[ ] Review security.py for threat model alignment
|
||||
[ ] Review service.py for API integration fit
|
||||
[ ] Review importer.py changes for impact
|
||||
[ ] Review merger.py changes for safety
|
||||
```
|
||||
|
||||
### Step 2: Configuration
|
||||
```python
|
||||
# In your app initialization
|
||||
from dss.export_import.service import DSSProjectService
|
||||
from dss.export_import.security import (
|
||||
MemoryLimitManager,
|
||||
DatabaseLockingStrategy
|
||||
)
|
||||
|
||||
# Configure for your environment
|
||||
service = DSSProjectService(
|
||||
busy_timeout_ms=5000 # Adjust for your load
|
||||
)
|
||||
|
||||
memory_mgr = MemoryLimitManager(
|
||||
max_file_size=100_000_000, # 100MB
|
||||
max_tokens=10000,
|
||||
max_components=1000
|
||||
)
|
||||
```
|
||||
|
||||
### Step 3: Testing
|
||||
```bash
|
||||
# Test with small archives
|
||||
python -m dss.export_import.examples
|
||||
|
||||
# Test memory limits with medium archive
|
||||
# Test background job detection
|
||||
# Test error scenarios (corrupt archive, etc)
|
||||
# Load test with your largest projects
|
||||
```
|
||||
|
||||
### Step 4: Integration
|
||||
```python
|
||||
# Wrap API endpoints with service layer
|
||||
# Implement background job handler (Celery/RQ)
|
||||
# Add operation result webhooks
|
||||
# Set up monitoring
|
||||
```
|
||||
|
||||
### Step 5: Documentation
|
||||
```
|
||||
[ ] Update API documentation
|
||||
[ ] Document supported archive versions
|
||||
[ ] Document configuration options
|
||||
[ ] Create user guide for workflows
|
||||
[ ] Document troubleshooting procedures
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Breaking Changes: NONE ✅
|
||||
|
||||
**Fully backward compatible:**
|
||||
- Old archive versions still supported (auto-migration)
|
||||
- Existing model fields unchanged
|
||||
- Optional new security features
|
||||
- Service layer is new (doesn't replace existing code)
|
||||
- No changes to database schema
|
||||
|
||||
---
|
||||
|
||||
## Quick Start for Developers
|
||||
|
||||
### Using the Service Layer
|
||||
|
||||
```python
|
||||
from dss.export_import import DSSProjectService
|
||||
from pathlib import Path
|
||||
|
||||
# Initialize service
|
||||
service = DSSProjectService(busy_timeout_ms=5000)
|
||||
|
||||
# Export
|
||||
result = service.export_project(my_project, Path("export.dss"))
|
||||
assert result.success, result.error
|
||||
|
||||
# Import
|
||||
result = service.import_project(Path("import.dss"))
|
||||
assert result.success, result.error
|
||||
|
||||
# Merge with analysis
|
||||
analysis = service.analyze_merge(local_project, Path("updates.dss"))
|
||||
result = service.merge_project(
|
||||
local_project,
|
||||
Path("updates.dss"),
|
||||
conflict_strategy='keep_local'
|
||||
)
|
||||
assert result.success, result.error
|
||||
```
|
||||
|
||||
### Using Security Utilities
|
||||
|
||||
```python
|
||||
from dss.export_import.security import (
|
||||
ZipSlipValidator,
|
||||
MemoryLimitManager,
|
||||
TimestampConflictResolver
|
||||
)
|
||||
|
||||
# Check archive for Zip Slip
|
||||
safe, unsafe = ZipSlipValidator.validate_archive_members(archive.namelist())
|
||||
if not safe:
|
||||
print(f"Unsafe paths: {unsafe}")
|
||||
|
||||
# Check memory limits
|
||||
mem = MemoryLimitManager()
|
||||
ok, error = mem.check_file_size(file_size)
|
||||
ok, error = mem.check_token_count(token_count)
|
||||
|
||||
# Resolve conflicts safely
|
||||
from datetime import datetime
|
||||
resolver = TimestampConflictResolver()
|
||||
winner, warning = resolver.resolve_conflict(
|
||||
datetime(2025, 1, 1),
|
||||
datetime(2025, 1, 2)
|
||||
)
|
||||
if warning:
|
||||
print(f"⚠️ {warning}") # Clock skew warning
|
||||
```
|
||||
|
||||

|
||||
|
||||
