The β€œProof-of-State” Trap

Why your agent dies after every restart. Four real production autopsies (#113434, #114234, #114255, #115326) that look unrelated but share one root cause β€” and the invariant that kills the whole family.

The Four Pillars

πŸ›‘

Idempotency Guard

Prevents duplicate tool execution. Same call twice? Only runs once. Stripe-grade safety for your agents.

⚑

Circuit Breaker

Auto-meltdown β†’ safe fallback. GPT-4 fails 3 times? ARK switches to Claude. Your agent never crashes.

πŸ”§

Output Validator

Validates every agent output against a schema. Catches "the agent said it charged $10 but actually wrote 'hello world'".
