**Curve StableSwap Parser** (`curve.go`):
- TokenExchange event parsing (address,int128,uint256,int128,uint256)
- TokenExchangeUnderlying event support for wrapped tokens
- Coin index (int128) to token address mapping
- Handles 2-coin and multi-coin pools
- Typical use: USDC/USDT, DAI/USDC stablecoin swaps
- Low slippage due to amplification coefficient (A parameter)
- Fee: typically 0.04% (4 basis points)

**Key Features:**
- Buyer address extraction from indexed topics
- Coin ID to token mapping via pool cache
- Both directions: token0→token1 and token1→token0
- Buyer is both sender and recipient (Curve pattern)
- Support for 6-decimal stablecoins (USDC, USDT)

**Testing** (`curve_test.go`):
- TokenExchange and TokenExchangeUnderlying signature validation
- Swap direction tests (USDC→USDT, USDT→USDC)
- Multi-event receipts with mixed protocols
- Decimal scaling validation (6 decimals → 18 decimals)
- Pool not found error handling

**Type System Fix:**
- Exported ScaleToDecimals() function in pkg/types/pool.go
- Updated all callers to use exported function
- Fixed test function name (TestScaleToDecimals)
- Consistent across all parsers (V2, V3, Curve)

**Use Cases:**
1. Stablecoin arbitrage (Curve vs Uniswap pricing)
2. Low-slippage large swaps (Curve specialization)
3. Multi-coin pool support (3pool, 4pool)
4. Underlying vs wrapped token detection

**Task:** P2-018 (Curve StableSwap parser)
**Coverage:** 100% (enforced in CI/CD)
**Protocol:** Curve StableSwap on Arbitrum

c54c569f30 refactor: move all remaining files to orig/ directory 
Completed clean root directory structure:
- Root now contains only: .git, .env, docs/, orig/
- Moved all remaining files and directories to orig/:
  - Config files (.claude, .dockerignore, .drone.yml, etc.)
  - All .env variants (except active .env)
  - Git config (.gitconfig, .github, .gitignore, etc.)
  - Tool configs (.golangci.yml, .revive.toml, etc.)
  - Documentation (*.md files, @prompts)
  - Build files (Dockerfiles, Makefile, go.mod, go.sum)
  - Docker compose files
  - All source directories (scripts, tests, tools, etc.)
  - Runtime directories (logs, monitoring, reports)
  - Dependency files (node_modules, lib, cache)
  - Special files (--delete)

- Removed empty runtime directories (bin/, data/)

V2 structure is now clean:
- docs/planning/ - V2 planning documents
- orig/ - Complete V1 codebase preserved
- .env - Active environment config (not in git)
