✨ Claude-Generated Content

Summary

Adds comprehensive CLAUDE.md documentation files across the monorepo to provide AI coding assistants with detailed context about the codebase architecture, patterns, and conventions.

Changes

• Root CLAUDE.md: Added monorepo-level documentation covering all 11 SDKs, dependency graph, architecture overview, development workflow, and common integration patterns
• sdk-core/CLAUDE.md: Detailed documentation for the foundational SDK including entity system, fraction mathematics, and multi-chain address registry
• v3-sdk/CLAUDE.md: Documentation for concentrated liquidity AMM including tick system, position management, and NFT handling
• v4-sdk/CLAUDE.md: Documentation for hooks-based AMM with native ETH support and action encoding patterns
• router-sdk/CLAUDE.md: Multi-protocol routing documentation for cross-version trade execution
• universal-router-sdk/CLAUDE.md: Unified interface documentation for batched swap operations
• uniswapx-sdk/CLAUDE.md: Comprehensive documentation for off-chain order protocol including Dutch auctions, limit orders, and MEV protection
• permit2-sdk/CLAUDE.md: Documentation for gasless approval patterns and EIP-712 signatures
• flashtestations-sdk/CLAUDE.md: TEE attestation verification documentation for Unichain
• tamperproof-transactions/CLAUDE.md: EIP-7754 signature verification documentation

How Has This Been Tested?

Documentation-only changes; verified file structure and markdown formatting.

Are there any breaking changes?

No breaking changes. These are new documentation files that do not affect runtime behavior.

Notes

These CLAUDE.md files follow the documentation hierarchy pattern established in the root file, with SDK-specific files providing detailed implementation guidance while the root file serves as an ecosystem overview and navigation guide.
