+# Code Style & Conventions
+
+## TypeScript Standards
+- **Target**: ES2022
+- **Module System**: ESM with NodeNext resolution
+- **Decorators**: Experimental decorators enabled
+- **Strict Mode**: Implied through TypeScript configuration
+
+## Naming Conventions
+- **Interfaces**: Prefix with `I` (e.g., `IUserData`, `IConfig`)
+- **Types**: Prefix with `T` (e.g., `TResponseType`, `TQueryResult`)
+- **Classes**: PascalCase (e.g., `SmartdataDb`, `SmartDataDbDoc`)
+- **Files**: All lowercase (e.g., `classes.doc.ts`, `plugins.ts`)
+- **Methods**: camelCase (e.g., `findOne`, `saveToDb`)
+
+## Import Patterns
+- All external dependencies imported in `ts/plugins.ts`
+- Reference as `plugins.moduleName.method()`
+- Use full import paths for internal modules
+- Maintain ESM syntax throughout
+
+## Class Structure
+- Use decorators for MongoDB document definitions
+- Extend base classes (SmartDataDbDoc, SmartDataDbCollection)
+- Static methods for factory patterns
+- Instance methods for document operations
+
+## Async Patterns
+- Preserve Promise-based patterns
+- Use async/await for clarity
+- Handle errors appropriately
+- Return typed Promises
+
+## MongoDB Specifics
+- Use `@unify()` decorator for unique fields
+- Use `@svDb()` decorator for database fields
+- Implement proper serialization/deserialization
+- Type-safe query construction with DeepQuery<T>
+
+## Testing Patterns
+- Import from `@git.zone/tstest/tapbundle`
+- End test files with `export default tap.start()`
+- Use descriptive test names
+- Cover edge cases and error conditions

+# Project Overview: @push.rocks/smartdata
+
+## Purpose
+An advanced TypeScript-first MongoDB wrapper library providing enterprise-grade features for distributed systems, real-time data synchronization, and easy data management.
+
+## Tech Stack
+- **Language**: TypeScript (ES2022 target)
+- **Runtime**: Node.js >= 16.x
+- **Database**: MongoDB >= 4.4
+- **Build System**: tsbuild
+- **Test Framework**: tstest with tapbundle
+- **Package Manager**: pnpm (v10.7.0)
+- **Module System**: ESM (ES Modules)
+
+## Key Features
+- Type-safe MongoDB integration with decorators
+- Document management with automatic timestamps
+- EasyStore for key-value storage
+- Distributed coordination with leader election
+- Real-time data sync with RxJS watchers
+- Deep query type safety
+- Enhanced cursor API
+- Powerful search capabilities
+
+## Project Structure
+- **ts/**: Main TypeScript source code
+  - Core classes for DB, Collections, Documents, Cursors
+  - Distributed coordinator, EasyStore, Watchers
+  - Lucene adapter for search functionality
+- **test/**: Test files using tstest framework
+- **dist_ts/**: Compiled JavaScript output
+
+## Key Dependencies
+- MongoDB driver (v6.18.0)
+- @push.rocks ecosystem packages
+- @tsclass/tsclass for decorators
+- RxJS for reactive programming

+# Suggested Commands for @push.rocks/smartdata
+
+## Build & Development
+- `pnpm build` - Build the TypeScript project with web support
+- `pnpm buildDocs` - Generate documentation using tsdoc
+- `tsbuild --web --allowimplicitany` - Direct build command
+
+## Testing
+- `pnpm test` - Run all tests in test/ directory
+- `pnpm testSearch` - Run specific search test
+- `tstest test/test.specific.ts --verbose` - Run specific test with verbose output
+- `tsbuild check test/**/* --skiplibcheck` - Type check test files
+
+## Package Management
+- `pnpm install` - Install dependencies
+- `pnpm install --save-dev <package>` - Add dev dependency
+- `pnpm add <package>` - Add production dependency
+
+## Version Control
+- `git status` - Check current changes
+- `git diff` - View uncommitted changes
+- `git log --oneline -10` - View recent commits
+- `git mv <old> <new>` - Move/rename files preserving history
+
+## System Utilities (Linux)
+- `ls -la` - List all files with details
+- `grep -r "pattern" .` - Search for pattern in files
+- `find . -name "*.ts"` - Find TypeScript files
+- `ps aux | grep node` - Find Node.js processes
+- `lsof -i :80` - Check process on port 80
+
+## Debug & Development
+- `tsx <script.ts>` - Run TypeScript file directly
+- Store debug scripts in `.nogit/debug/`
+- Curl endpoints for API testing

+# Task Completion Checklist
+
+When completing any coding task in this project, always:
+
+## Before Committing
+1. **Build the project**: Run `pnpm build` to ensure TypeScript compiles
+2. **Run tests**: Execute `pnpm test` to verify nothing is broken
+3. **Type check**: Verify types compile correctly
+4. **Check for lint issues**: Look for any code style violations
+
+## Code Quality Checks
+- Verify all imports are in `ts/plugins.ts` for external dependencies
+- Check that interfaces are prefixed with `I`
+- Check that types are prefixed with `T`
+- Ensure filenames are lowercase
+- Verify async patterns are preserved where needed
+- Check that decorators are properly used for MongoDB documents
+
+## Documentation
+- Update relevant comments if functionality changed
+- Ensure new exports are properly documented
+- Update readme.md if new features added (only if explicitly requested)
+
+## Git Hygiene
+- Make small, focused commits
+- Write clear commit messages
+- Use `git mv` for file operations
+- Never commit sensitive data or keys
+
+## Final Verification
+- Test the specific functionality that was changed
+- Ensure no unintended side effects
+- Verify the change solves the original problem completely
