Term	Kind	Topic	What it is
Degradation Blindness Binary Health Thinking, Up-Or-Down Fallacy, Slow-Is-Not-Down	concept	Failure Thinking	Designing and monitoring for components that are either working or failed, when the dangerous and more common state is working slowly - which health checks report as healthy and retries make worse.
Failure Thinking Pre-mortem, Failure Analysis	practice	Failure Thinking	The habit of asking what happens when each part fails, applied systematically during design rather than during the incident.
Pre-Mortem	practice	Failure Thinking	An exercise in which a team imagines a project has already failed and explains why, surfacing risks that a forward-looking risk assessment misses.
Silent Quality Regression Payload-Level Degradation, Unasserted Output Failure	concept	Failure Thinking	A defect that leaves status codes, latency and throughput normal while making the content of responses worse - so every envelope-level alert stays green and the only available signal is statistical.
