errorsit

Errorsit is a term used in discussions of software reliability to describe a concept or practice related to error handling and observability. It is not a formal standard, and its definition varies among practitioners; in general it refers to how errors are captured, represented, and acted upon within a system.

Etymology and usage: The word appears in blog posts, design notes, and conference discussions as a neologism without a single agreed meaning. Depending on the context, errorsit can denote either a point in code designed to produce or detect errors, or a broader approach to treating errors as first-class entities in system design.

Common interpretations include: a deliberate error-site or fault-injection point intended to trigger and observe failure behavior; an architectural pattern that models error events as explicit signals with typed categories, structured logs, and defined remediation paths; and a testing methodology that focuses on reproducing and diagnosing error scenarios to improve resilience.

In practice, proponents of errorsit emphasize observability and consistent error handling: capturing rich contextual data around failures, using typed error objects rather than opaque exceptions, and ensuring coherent responses across services and layers.
