v2.5.0 — @vial-agent/core Extracted + Comparison Agent

What's New

@vial-agent/core — Generic Self-Healing Framework

Extracted the universal self-healing engine into its own package. Vial powers Helix and can power any agent:

npm install @vial-agent/core

• 34 engine modules: PCEC, Gene Map, wrap(), Meta-Learning, Safety Verification, Self-Play, Federated Learning, Adaptive Weights, Causal Graph, and more
• 37 exports: PcecEngine, GeneMap, wrap, AdapterRegistry, evaluate, simulate, all learning modules
• VialPlatformAdapter interface: implement for any domain (API monitoring, DevOps, CI/CD)
• Zero dependencies beyond better-sqlite3

Before/After Comparison Agent

Side-by-side agent comparison with realistic error distribution:

• Error distribution: nonce 40% | gas 25% | rate_limit 20% | balance 10%
• WITHOUT Helix: ~30% failure rate
• WITH Helix: 0% failures, 100% repair rate
• Config: DURATION_MS, TX_INTERVAL_MS, ERROR_RATE
