Author the repository's INTENT: the cluster runtime layer — turning hardened servers into a healthy, ready-to-use orchestration platform for workloads, configured to a consistent baseline and proven healthy before higher layers deploy onto it. Kept self-coherent and reference-free: describes this repository's own purpose at the abstract, stable level, with no external project or dependency-product references.

INTENT
This file captures why this repository exists, the direction it is moving toward, and the kind of system it is meant to become. It is intentionally aspirational and stable, not a description of current implementation.
One-liner
The cluster runtime layer — turning hardened servers into a healthy, ready-to-use orchestration platform for workloads.
Why This Exists
A hardened set of servers is not yet somewhere workloads can run. Something must install and configure the orchestration runtime — its scheduler, networking, ingress, admission controls, and the operators that extend it — and then prove the cluster is healthy.
Without a disciplined runtime layer:
- cluster configuration drifts between environments,
- extension and addon boundaries blur,
- and higher layers deploy onto an unproven runtime.
This layer exists to provide that runtime consistently and verifiably, so the layers above can deploy onto a known-good cluster.
The Mission
Where we are going.
To become the canonical home for the cluster runtime — installation and baseline configuration of the orchestrator, its networking and ingress, admission controls, cluster-level operators and addons, and runtime access — operated to a verified-healthy standard.
This means:
- The runtime is configured to a consistent baseline every time
- Cluster health is proven by tests, not assumed
- Capabilities are extended through operators and addons behind clear boundaries
- Runtime access is managed and rotatable
Core Principles
1. Runtime, Not Workloads
Provide the place where things run. Do not own the things that run there.
2. Healthy by Verification
Cluster health is demonstrated by smoke tests and checks, never assumed.
3. Consistent Baseline
The runtime is brought up the same way every time, so environments stay comparable and predictable.
4. Built on a Verified Substrate
Assumes a converged, hardened foundation beneath it; it does not reach down and reconfigure that foundation.
5. Extensible by Operators
Cluster capabilities are added through operators and addons within clear boundaries, not by ad-hoc mutation.
6. Managed Access
Access to the runtime is controlled, auditable, and rotatable.
What This Is (Conceptually)
This layer is:
- a cluster runtime layer
- an orchestrator installation and configuration
- a networking, ingress, and admission baseline
- a host for cluster-level operators and addons
- a health-verification gate
- runtime access management
What This Is Not
This layer is not:
- the infrastructure substrate beneath it
- a provider of shared, stateful platform services
- an application or business-capability provider
- an owner of the workloads it runs
It is the runtime an entire landscape's workloads depend on.
Direction of Evolution
This layer is expected to evolve toward:
- Stronger, continuous health verification
- Smoother, safer runtime upgrades
- Clearer operator and addon boundaries
- More robust access rotation
- Self-evidencing, auditable runtime state
Guiding Question
How can the runtime an entire landscape's workloads depend on be made consistently healthy, upgradable, and trustworthy?
