Operational Contracts¶

Operational contracts define the stable expectations operators can rely on around health, readiness, observability, and runtime behavior.

Operational Contract Scope¶

    Ops[Operational contracts] --> Health[Health and readiness]
    Ops --> Metrics[Metrics]
    Ops --> Runtime[Runtime validation]

This operational-scope diagram shows the stable operator-facing surfaces Atlas expects deployments to rely on intentionally.

Operator Promise Model¶

flowchart TD
    Promise[Operational promise] --> Checks[Checks and evidence]
    Checks --> Deploy[Safe deployment use]

This promise model explains how operational contracts should stay credible: they must connect to checks and evidence that operators can actually use during deployment and recovery.

Main Promise Areas¶

health and readiness semantics
metrics and observability surfaces
runtime validation behavior
explicit operator-visible error conditions

Purpose¶

This page defines the Atlas contract expectations for operational contracts. Use it when you need the explicit compatibility promise rather than a workflow narrative.

Stability¶

This page is part of the checked-in contract surface. Changes here should stay aligned with tests, generated artifacts, and release evidence.
