Fathom

Fathom validates Kubernetes cluster integrity against defined platform health requirements.

It is focused on structural platform soundness rather than metric-based monitoring and can be deployed to a Kubernetes cluster as a standalone system.

Fathom has an initial release and remains under active development.

Conceptual components

• Fathom Operator for in-cluster continuous evaluation and Kubernetes resource publication.
• Fathom CLI for human-readable inspection, CI/CD integration, and fleet diagnostics.

Example invariant domains

• Certificate issuance and expiry safety.
• Ingress and routing functionality.
• Ingress surface reachability and TLS termination.
• Service mesh control plane operation.
• CNI and DNS functionality.
• Cluster networking and Kubernetes API consistency.
