feat(v2): achieve 100% safety test passage with emergency stop and Uniswap V3 pricing
This commit achieves 100% test passage (12/12 tests) for all safety mechanisms
and adds comprehensive Uniswap V3 pricing library.
## Key Achievements
**Test Results: 12/12 passing (100%)**
- Previous: 6/11 passing (54.5%)
- Current: 12/12 passing (100%)
- All safety-critical tests verified
## Changes Made
### 1. Emergency Stop Mechanism (cmd/mev-bot-v2/main.go)
- Added monitorEmergencyStop() function with 10-second check interval
- Monitors /tmp/mev-bot-emergency-stop file
- Triggers graceful shutdown when file detected
- Logs emergency stop detection with clear error message
- Modified main event loop to handle both interrupt and context cancellation
### 2. Safety Configuration Logging (cmd/mev-bot-v2/main.go:49-80)
- Added comprehensive structured logging at startup
- Logs execution settings (dry_run_mode, enable_execution, enable_simulation)
- Logs risk limits (max_position_size, max_daily_volume, max_slippage)
- Logs profit thresholds (min_profit, min_roi, min_swap_amount)
- Logs circuit breaker settings (max_consecutive_losses, max_hourly_loss)
- Logs emergency stop configuration (file_path, check_interval)
### 3. Config Struct Enhancements (cmd/mev-bot-v2/main.go:297-325)
- Added MaxGasPrice uint64 field
- Added EnableExecution bool field
- Added DryRun bool field
- Added Safety section with:
- MaxConsecutiveLosses int
- MaxHourlyLoss *big.Int
- MaxDailyLoss *big.Int
- EmergencyStopFile string
### 4. Production Environment Configuration (cmd/mev-bot-v2/main.go:364-376)
- LoadConfig() now supports both old and new env var names
- RPC_URL with fallback to ARBITRUM_RPC_ENDPOINT
- WS_URL with fallback to ARBITRUM_WS_ENDPOINT
- EXECUTOR_CONTRACT with fallback to CONTRACT_ARBITRAGE_EXECUTOR
- Copied production .env from orig/.env.production.secure
### 5. Uniswap V3 Pricing Library (pkg/pricing/uniswap_v3.go)
Based on Python notebooks: https://github.com/t4sk/notes/tree/main/python/uniswap-v3
Functions implemented:
- SqrtPriceX96ToPrice() - Convert Q64.96 to human-readable price
- TickToPrice() - Convert tick to price (1.0001^tick)
- SqrtPriceX96ToTick() - Reverse conversion with clamping
- PriceToTick() - Price to tick conversion
- TickToSqrtPriceX96() - Tick to Q64.96 format
- GetPriceImpact() - Calculate price impact in BPS
- GetTickSpacing() - Fee tier to tick spacing mapping
- GetNearestUsableTick() - Align tick to spacing
### 6. Test Script Improvements (scripts/test_safety_mechanisms.sh)
**Emergency Stop Test Fix (lines 323-362):**
- Changed to use `podman exec` to create file inside container
- Better error handling and logging
- Proper detection verification
**Nonce Check Test Fix (lines 412-463, 468-504):**
- Capture nonce before swap in test 9
- Calculate delta instead of checking absolute value
- Properly verify bot created 0 transactions in dry-run mode
- Fixes false negative from forked account history
### 7. Smart Contracts Submodule (.gitmodules)
- Added mev-beta-contracts as git submodule at contracts/
- URL: ssh://git@194.163.145.241:2222/copper-tone-tech/mev-beta-contracts.git
- Enables parallel development of bot and contracts
## Test Results Summary
All 12 tests passing:
1. ✅ Anvil fork startup
2. ✅ Test account balance verification
3. ✅ Safety configuration creation
4. ✅ Docker image build
5. ✅ Bot deployment
6. ✅ Safety configuration verification (5/5 checks)
7. ✅ Emergency stop detection (8 seconds)
8. ✅ Circuit breaker configuration
9. ✅ Position size limits
10. ✅ Test swap creation
11. ✅ Swap detection
12. ✅ Dry-run mode verification (0 bot transactions)
## Safety Features Verified
- Dry-run mode prevents real transactions ✓
- Circuit breaker configured (3 losses, 0.1 ETH hourly, 0.5 ETH daily) ✓
- Position limits enforced (10 ETH max position, 100 ETH daily volume) ✓
- Emergency stop file monitoring active ✓
- Comprehensive logging for monitoring ✓
## Next Steps
The bot is now ready for Anvil fork testing with all safety mechanisms verified.

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)
