+# SPARC Implementation Plan for RvLite
+
+## Overview
+
+**RvLite** (RuVector-Lite) is a standalone, WASM-first vector database with graph and semantic capabilities that runs anywhere - browser, Node.js, Deno, Bun, edge workers - without requiring PostgreSQL.
+
+This document outlines the complete implementation using **SPARC methodology**:
+- **S**pecification - Requirements, features, constraints
+- **P**seudocode - High-level algorithms and data structures
+- **A**rchitecture - System design and component interaction
+- **R**efinement - Detailed implementation with TDD
+- **C**ompletion - Integration, optimization, deployment
+
+## Project Goals
+
+### Primary Objectives
+1. **Zero Dependencies** - No PostgreSQL, Docker, or native compilation required
+2. **Universal Runtime** - Browser, Node.js, Deno, Bun, Cloudflare Workers
+3. **Full Feature Parity** - All ruvector-postgres capabilities (SQL, SPARQL, Cypher, GNN, learning)
+4. **Lightweight** - ~5-6MB WASM bundle (gzipped)
+5. **Production Ready** - Persistent storage, ACID transactions, crash recovery
+
+### Success Metrics
+- Bundle size: < 6MB gzipped
+- Load time: < 1s in browser
+- Query latency: < 20ms for 1k vectors
+- Memory usage: < 200MB for 100k vectors
+- Browser support: Chrome 91+, Firefox 89+, Safari 16.4+
+- Test coverage: > 90%
+

+
+## Development Workflow
+
+### 1. Test-Driven Development (TDD)
+Every feature follows:
+```
+1. Write failing test
+2. Implement minimal code to pass
+3. Refactor for quality
+4. Document and review
+```
+
+### 2. Continuous Integration
+```
+On every commit:
+  ├─ cargo test (Rust unit tests)
+  ├─ wasm-pack test (WASM tests)
+  ├─ npm test (TypeScript integration tests)
+  ├─ cargo clippy (linting)
+  └─ cargo fmt --check (formatting)
+```
+
+### 3. Quality Gates
+- All tests must pass
+- Code coverage > 90%
+- No clippy warnings
+- Documentation complete
+- Performance benchmarks green
+
+## Key Technologies
+
+### Rust Crates
+- **wasm-bindgen** - WASM/JS interop
+- **serde** - Serialization
+- **dashmap** - Concurrent hash maps
+- **parking_lot** - Synchronization
+- **simsimd** - SIMD operations
+- **half** - f16 support
+- **rkyv** - Zero-copy serialization
+
+### JavaScript/TypeScript
+- **wasm-pack** - WASM build tool
+- **TypeScript 5+** - Type-safe API
+- **Vitest** - Testing framework
+- **tsup** - TypeScript bundler
+
+### Build Tools
+- **cargo** - Rust package manager
+- **wasm-pack** - WASM compiler
+- **pnpm** - Fast npm client
+- **GitHub Actions** - CI/CD
