fix(multicall): resolve critical multicall parsing corruption issues
- Added comprehensive bounds checking to prevent buffer overruns in multicall parsing - Implemented graduated validation system (Strict/Moderate/Permissive) to reduce false positives - Added LRU caching system for address validation with 10-minute TTL - Enhanced ABI decoder with missing Universal Router and Arbitrum-specific DEX signatures - Fixed duplicate function declarations and import conflicts across multiple files - Added error recovery mechanisms with multiple fallback strategies - Updated tests to handle new validation behavior for suspicious addresses - Fixed parser test expectations for improved validation system - Applied gofmt formatting fixes to ensure code style compliance - Fixed mutex copying issues in monitoring package by introducing MetricsSnapshot - Resolved critical security vulnerabilities in heuristic address extraction - Progress: Updated TODO audit from 10% to 35% complete 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

|
||||
- `mev_bot_trade_error_rate`, `mev_bot_processing_latency_ms`, `mev_bot_successful_trades`
|
||||
- Track these in Grafana to watch hit rate, latency, and cumulative P&L during deployments.
|
||||
- **Historical replay harness**:
|
||||
- Run `make simulate-profit` (or `./scripts/run_profit_simulation.sh <report-dir>`) to analyse bundled vectors under `tools/simulation/vectors/`.
|
||||
- The CLI produces JSON and Markdown reports in `reports/simulation/latest/` summarising hit rate, gas burn, and per-exchange profitability.
|
||||
- **Runbook checklist**:
|
||||
1. Execute the profitability simulation ahead of staging/production releases and attach the Markdown summary to change records.
|
||||
2. During rollout, alert if `mev_bot_trade_error_rate` exceeds 0.25 for more than 10 minutes or if `mev_bot_net_profit_eth` trends negative across a 15-minute window.
|
||||
3. Archive both math audit (`reports/math/latest/`) and simulation (`reports/simulation/latest/`) artifacts with deployment notes.

> Tip: For a ready-to-use smoke test profile, source `env/smoke.env`. The sample file seeds a compliant encryption key, keystore paths, and metrics defaults so `./mev-bot start` can boot locally without exposing production secrets. Replace the placeholder RPC endpoints before connecting to real infrastructure.
|
||||
|
||||
Ensure the paths in `MEV_BOT_KEYSTORE_PATH`, `MEV_BOT_AUDIT_LOG`, and `MEV_BOT_BACKUP_PATH` exist on the host; the helper scripts (`scripts/run.sh`, `env/smoke.env`) create sane defaults under `keystore/`, `logs/`, and `backups/` if they are missing.
