Probabilistic Resilience Engineering

Adaptive Resilience Operations

Chaos Engineering for the Age of Agentic AI

AI doesn't break — it drifts... and drift kills silently.

"Because the future is probabilistic, our operations must be adaptive."

What is Probabilistic Resilience Engineering?

A paradigm shift from testing binary failures to measuring distribution drift in AI systems.

🎯

The New Question

Stop asking "Does it break?" Start asking "How does the probability distribution shift when X becomes unreliable?"

Semantic Circuit Breakers

Circuit breakers that trip not because the server crashed, but because the physics of the conversation became unstable.

📊

Physics of Failure

Measure cascade entropy, amplification ratios, and coherence tension — the thermodynamics of agentic systems.

The Metrics That Matter

AC < 1
Cascade Amplification
Did the system amplify the error, or contain it? The new SLA.
Hcascade
Cascade Entropy
Shannon entropy applied to error propagation. Not metaphor — measurement.
CTI
Coherence Tension Index
The stress fracture before the break. High CTI = destined to fail.

AI Resilience for Everyone

For Platform Teams

Test Before Failures Cascade

Inject hallucinations, simulate drift, stress multi-agent coordination. Find the failure modes before your users do.

For AI Engineers

Build Systems That Adapt

Circuit breakers for confidence. Containment for cascades. Systems that detect and respond, not just fail.

For Engineering Leaders

Understand Operational Risk

Cost as a reliability metric. Trust tiers for AI dependencies. A framework for reasoning about probabilistic systems.
