+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Holos is a configuration management tool for Kubernetes that implements the rendered manifests pattern using CUE. It unifies Helm charts, Kustomize bases, and raw Kubernetes manifests into a single, declarative pipeline.
+
+### Core Flow
+```
+Platform → Components → BuildPlan → Generators → Transformers → Validators → Manifests
+```
+
+## Key Commands
+
+```bash
+# Development
+make build         # Build the binary
+make install       # Install binary (REQUIRED before testing holos commands)
+make test          # Run all tests
+make fmt           # Format Go code
+make lint          # Run linters
+make coverage      # Generate coverage report
+
+# Documentation
+make update-docs   # Update generated docs
+make website       # Build the documentation website
+
+# Usage (run 'make install' first to test code changes)
+holos render platform    # Render entire platform
+holos render component   # Render single component
+holos show buildplans    # Show build plans
+holos init platform      # Initialize new platform
+```
+
+## Architecture
+
+### Directory Structure
+- `/api/` - API definitions (v1alpha5 stable, v1alpha6 in development)
+- `/cmd/` - CLI entry point
+- `/internal/cli/` - Command implementations
+- `/internal/component/` - Component handling logic
+- `/internal/platform/` - Platform handling logic
+- `/internal/generate/` - Code generation
+
+### Key Files
+- `/internal/cli/render/render.go` - Core render logic
+- `/internal/component/component.go` - Component processing
+- `/api/core/v1alpha*/types.go` - API type definitions
+
+### Component Types
+1. **Helm** - Wraps Helm charts
+2. **Kustomize** - Wraps Kustomize bases  
+3. **Kubernetes** - Raw Kubernetes manifests
+
+## CUE Patterns
+
+Components are defined in CUE:
+```cue
+package holos
+
+holos: Component.BuildPlan
+
+Component: #Helm & {
+    Name: "example"
+    Chart: {
+        version: "1.0.0"
+        repository: {
+            name: "example"
+            url:  "https://charts.example.com"
+        }
+    }
+}
+```
+
+## Testing
+
+- Unit tests: `*_test.go` files colocated with source
+- Integration tests: `/cmd/holos/tests/`
+- Example platforms: `/internal/testutil/fixtures/`
+- Run single test: `go test -run TestName ./path/to/package`
+
+## Development Patterns
+
+1. Error handling: Prefer `errors.Format()` from `/internal/errors/` over `fmt.Errorf()`
+2. Logging: Use structured `slog`, get logger with `logger.FromContext(ctx)`
+3. CLI commands: Follow Cobra patterns in `/internal/cli/`
+4. CUE formatting: Always run `cue fmt` on CUE files
+5. Go formatting: Always run `go fmt` on go files
+6. Develop against v1alpha6 packages.
+7. Commits: Use the package name as the first word in the commit, lower case.  Commit without asking permission.  Always run `make lint` and `make test` before committing.
+
+## Version Management
+
+- Version files: `/version/embedded/{major,minor,patch}`
+- Bump version: `make bump`
+- API versions: v1alpha5 (stable), v1alpha6 (development)
+
+## Key Concepts
+
+- **Platform**: Top-level configuration containing all components
+- **Component**: Unit of configuration (DAG of Tasks producing deployment configs for one component)
+- **TaskSet**: DAG of Tasks (Similar to how make tasks behave)
+- **BuildPlan**: Instructions for building a component.  Deprecated in v1alpha6, use TaskSet instead.
+- **Generator**: Creates manifests (Helm, Kustomize, etc.) author schema only in v1alpha6
+- **Transformer**: Modifies generated manifests, author schema only in v1alpha6
+- **Validator**: Validates final manifests, author schema only in v1alpha6
+
+## Resources
+
+- Tutorials: `/doc/md/tutorial/`
+- Platform templates: `/internal/generate/platforms/`
+- Test fixtures: `/internal/testutil/fixtures/`
+- Core schemas: `/api/core/` (Abstraction over low level data pipeline tasks)
+- Author schemas: `/api/author/` (User facing abstractions over core Schemas)

-Building and maintaining a software development platform is a complex and time
-consuming endeavour.  Organizations often dedicate a team of 3-4 who need 6-12
-months to build the platform.
+[Holos] is a configuration management tool for Kubernetes implementing the
+[rendered manifests pattern]. It handles configurations ranging from single
+resources to multi-cluster platforms across regions.
 
-Holos is a tool and a reference platform to reduce the complexity and speed up
-the process of building a modern, cloud native software development platform.
+Key components:
+- Platform schemas defining component integration
+- Building blocks unifying Helm, Kustomize and Kubernetes configs with CUE
+- BuildPlan pipeline for generating, transforming and validating manifests
 
-- **Accelerate new projects** - Reduce time to market and operational complexity by starting your new project on top of the Holos reference platform.
-- **Modernize existing projects** - Incrementally incorporate your existing platform services into Holos for simpler integration.
-- **Unified configuration model** - Increase safety and reduce the risk of config changes with CUE.
-- **First class Helm and Kustomize support** - Leverage and reuse your existing investment in existing configuration tools such as Helm and Kustomize.
-- **Modern Authentication and Authorization** - Holos seamlessly integrates platform identity and access management with zero-trust beyond corp style authorization policy.

+
+## Organizational Role
+
+Platform engineers use Holos to generate Kubernetes manifests, both locally and
+in CI pipelines. The manifests are committed to version control and deployed via
+GitOps tools like ArgoCD or Flux.
+
+Holos integrates seamlessly with existing Helm charts, Kustomize bases, and
+other version-controlled configurations.
+
+## Advantages of Holos
+
+### Safe
+
+Holos leverages [CUE] for strong typing and validation of configuration data,
+ensuring consistent output from Helm and other tools.
+
+### Consistent
+
+A unified pipeline processes all configurations - whether from CUE, Helm, or
+Kustomize - through the same well-defined stages.
+
+### Flexible
+
+Composable building blocks for generation, transformation, validation and
+integration let teams assemble workflows that match their needs.
+
+The core is intentionally unopinionated about platform configuration patterns.
+Common needs like environments and clusters are provided as customizable
+[topics] recipes rather than enforced structures.

+Get support through our [Discord] channel or [GitHub discussions]. Configuration
+challenges arise at all experience levels - we welcome your questions and are

+
+Package author contains a standard set of schemas for component authors to generate common [core](<https://holos.run/docs/api/core/>) BuildPlans.
+
+Holos values stability, flexibility, and composition. This package intentionally defines only the minimal necessary set of structures. Component authors are encouraged to define their own structures building on our example [topics](<https://holos.run/docs/topics/>).
+
+The Holos Maintainers may add definitions to this package if the community identifies nearly all users must define the exact same structure. Otherwise, definitions should be added as a customizable example in [topics](<https://holos.run/docs/topics/>).

+For example, structures representing a cluster and environment almost always need to be defined. Their definition varies from one organization to the next. Therefore, customizable definitions for a cluster and environment are best maintained in [topics](<https://holos.run/docs/topics/>), not standardized in this package.

+## Constants
+
+<a name="BuildContextTag"></a>BuildContextTag represents the cue tag holos render component uses to inject the json representation of a [BuildContext](<#BuildContext>) for use in a BuildPlan.
+
+```go
+const BuildContextTag string = "holos_build_context"
+```
+
+<a name="ComponentAnnotationsTag"></a>ComponentAnnotationsTag represents the tag holos uses to inject the json representation of [Component](<#Component>) metadata annotations from the holos render platform command to the holos render component command.
+
+```go
+const ComponentAnnotationsTag = "holos_component_annotations"
+```
+
+<a name="ComponentLabelsTag"></a>ComponentLabelsTag represents the cue tag holos uses to inject the json representation of [Component](<#Component>) metadata labels from the holos render platform command to the holos render component command.
+
+```go
+const ComponentLabelsTag string = "holos_component_labels"
+```
+
+<a name="ComponentNameTag"></a>ComponentNameTag represents the cue tag holos uses to inject a [Component](<#Component>) name from the holos render platform command to the holos render component command.
+
+```go
+const ComponentNameTag string = "holos_component_name"
+```
+
+<a name="ComponentPathTag"></a>ComponentPathTag represents the cue tag holos uses to inject a [Component](<#Component>) path relative to the cue module root from the holos render platform command to the holos render component command.
+
+```go
+const ComponentPathTag string = "holos_component_path"
+```
+
+<a name="Artifact"></a>
+## type Artifact {#Artifact}
+
+Artifact represents one fully rendered manifest produced by a [Transformer](<#Transformer>) sequence, which transforms a [Generator](<#Generator>) collection. A [BuildPlan](<#BuildPlan>) produces an [Artifact](<#Artifact>) collection.
+
+Each Artifact produces one manifest file or directory artifact. Generator Output values are used as Transformer Inputs. The Output field of the final [Transformer](<#Transformer>) should have the same value as the Artifact field.
+
+When there is more than one [Generator](<#Generator>) there should be at least one [Transformer](<#Transformer>) to combine outputs into one Artifact file, or the final artifact should be a directory containing the outputs of the generators. If there is a single Generator, it may directly produce the Artifact output.
+
+An Artifact is processed concurrently with other artifacts in the same [BuildPlan](<#BuildPlan>). One Artifact must not use an output of another Artifact as an input. Each [Generator](<#Generator>) within an artifact also runs concurrently with generators of the same artifact. Each [Transformer](<#Transformer>) is executed sequentially starting after all generators have completed.
+
+Output fields are write\-once. It is an error for multiple Generators or Transformers to produce the same Output value within the context of a [BuildPlan](<#BuildPlan>).
+
+When directories are used as inputs or outputs, they behave similar to how \`git\` works with directories. When the output field references a directory, all files within the directory are recursively stored using their relative path as a key. Similar to git add . When the input field references an absent file, a / is appended and the resulting value is used as a prefix match against all previous task outputs.
+
+```go
+type Artifact struct {
+    Artifact     FileOrDirectoryPath `json:"artifact,omitempty" yaml:"artifact,omitempty"`
+    Generators   []Generator         `json:"generators,omitempty" yaml:"generators,omitempty"`
+    Transformers []Transformer       `json:"transformers,omitempty" yaml:"transformers,omitempty"`

+    Skip         bool                `json:"skip,omitempty" yaml:"skip,omitempty"`
+}
+```
+
+<a name="Auth"></a>
+## type Auth {#Auth}
+
+Auth represents environment variable names containing auth credentials.
+
+```go
+type Auth struct {
+    Username AuthSource `json:"username" yaml:"username"`
+    Password AuthSource `json:"password" yaml:"password"`
+}
+```
+
+<a name="AuthSource"></a>
+## type AuthSource {#AuthSource}
+
+AuthSource represents a source for the value of an [Auth](<#Auth>) field.
+
+```go
+type AuthSource struct {
+    Value   string `json:"value,omitempty" yaml:"value,omitempty"`
+    FromEnv string `json:"fromEnv,omitempty" yaml:"fromEnv,omitempty"`
+}
+```
+
+<a name="BuildContext"></a>
+## type BuildContext {#BuildContext}
+
+BuildContext represents build context values owned by the holos render component command. End users should not manage context field values. End users may reference fields from within CUE to refer to late binding concrete values defined just before holos executes a [BuildPlan](<#BuildPlan>).
+
+Holos injects build context values by marshalling this struct to json through the holos\_build\_context cue tag.
+
+Example usage from cue to produce a [BuildPlan](<#BuildPlan>):
+
+```
+package holos

+}
+```
+
+<a name="BuildPlan"></a>
+## type BuildPlan {#BuildPlan}
+
+BuildPlan represents an implementation of the [rendered manifest pattern](<https://akuity.io/blog/the-rendered-manifests-pattern>). Holos processes a BuildPlan to produce one or more [Artifact](<#Artifact>) output files. BuildPlan artifact files usually contain Kubernetes manifests, but they may have any content.
+
+A BuildPlan usually produces two artifacts. One artifact contains a manifest of resources. A second artifact contains a GitOps resource to manage the first, usually an ArgoCD Application resource.
+
+Holos uses CUE to construct a BuildPlan. Holos injects late binding values such as the build temp dir using the [BuildContext](<#BuildContext>).
+
+```go
+type BuildPlan struct {
+    // APIVersion represents the versioned schema of the resource.
+    APIVersion string `json:"apiVersion" yaml:"apiVersion" cue:"\"v1alpha6\""`
+    // Kind represents the type of the resource.
+    Kind string `json:"kind" yaml:"kind" cue:"\"BuildPlan\""`
+    // Metadata represents data about the resource such as the Name.
+    Metadata Metadata `json:"metadata" yaml:"metadata"`
+    // Spec specifies the desired state of the resource.
+    Spec BuildPlanSpec `json:"spec" yaml:"spec"`
+    // BuildContext represents values injected by holos just before evaluating a
+    // BuildPlan, for example the tempDir used for the build.
+    BuildContext BuildContext `json:"buildContext" yaml:"buildContext"`
+}
+```
+
+<a name="BuildPlanSpec"></a>
+## type BuildPlanSpec {#BuildPlanSpec}
+
+BuildPlanSpec represents the specification of the [BuildPlan](<#BuildPlan>).
+
+```go
+type BuildPlanSpec struct {
+    // Artifacts represents the artifacts for holos to build.
+    Artifacts []Artifact `json:"artifacts" yaml:"artifacts"`
+    // Disabled causes the holos render platform command to skip the BuildPlan.
+    Disabled bool `json:"disabled,omitempty" yaml:"disabled,omitempty"`
+}
+```
+
+<a name="Chart"></a>
+## type Chart {#Chart}
+

+    Repository Repository `json:"repository,omitempty" yaml:"repository,omitempty"`
+}
+```
+
+<a name="Command"></a>
+## type Command {#Command}
+
+Command represents a [BuildPlan](<#BuildPlan>) task implemented by executing an user defined system command. A task is defined as a [Generator](<#Generator>), [Transformer](<#Transformer>), or [Validator](<#Validator>). Commands are executed with the working directory set to the platform root.
+
+```go
+type Command struct {
+    // DisplayName of the command.  The basename of args[0] is used if empty.
+    DisplayName string `json:"displayName,omitempty" yaml:"displayName,omitempty"`
+    // Args represents the argument vector passed to the os. to execute the
+    // command.
+    Args []string `json:"args,omitempty" yaml:"args,omitempty"`
+    // IsStdoutOutput captures the command stdout as the task output if true.
+    IsStdoutOutput bool `json:"isStdoutOutput,omitempty" yaml:"isStdoutOutput,omitempty"`
+}
+```
+
+<a name="Component"></a>
+## type Component {#Component}
+
+Component represents the complete context necessary to produce a [BuildPlan](<#BuildPlan>) from a path containing parameterized CUE configuration.
+
+```go
+type Component struct {

+    // parameter that should always be user defined, never defined by Holos.
+    Parameters map[string]string `json:"parameters,omitempty" yaml:"parameters,omitempty"`
+    // Labels represent selector labels for the component.  Holos copies Labels
+    // from the Component to the resulting BuildPlan.

+    // `app.holos.run/description` to customize the log message of each BuildPlan.
+    Annotations map[string]string `json:"annotations,omitempty" yaml:"annotations,omitempty"`
+}
+```
+
+<a name="File"></a>
+## type File {#File}
+
+File represents a simple single file copy [Generator](<#Generator>). Useful with a [Kustomize](<#Kustomize>) [Transformer](<#Transformer>) to process plain manifest files stored in the component directory. Multiple File generators may be used to transform multiple resources.
+
+```go
+type File struct {
+    // Source represents a file sub-path relative to the component path.
+    Source FilePath `json:"source" yaml:"source"`
+}
+```
+

+
+FileContent represents file contents.
+
+```go
+type FileContent string
+```
+
+<a name="FileContentMap"></a>
+## type FileContentMap {#FileContentMap}
+
+FileContentMap represents a mapping of file paths to file contents.
+
+```go
+type FileContentMap map[FilePath]FileContent
+```
+
+<a name="FileOrDirectoryPath"></a>
+## type FileOrDirectoryPath {#FileOrDirectoryPath}
+
+FileOrDirectoryPath represents a file or a directory path.
+
+```go
+type FileOrDirectoryPath string
+```
+
+<a name="FilePath"></a>
+## type FilePath {#FilePath}
+
+FilePath represents a file path.
+
+```go
+type FilePath string
+```
+
+<a name="Generator"></a>
+## type Generator {#Generator}
+
+Generator generates Kubernetes resources. [Helm](<#Helm>) and [Resources](<#Resources>) are the most commonly used, often paired together to mix\-in resources to an unmodified Helm chart. A simple [File](<#File>) generator is also available for use with the [Kustomize](<#Kustomize>) transformer.
+
+Each Generator in an [Artifact](<#Artifact>) must have a distinct Output value for a [Transformer](<#Transformer>) to reference.
+
+1. [Resources](<#Resources>) \- Generates resources from CUE code.
+2. [Helm](<#Helm>) \- Generates rendered yaml from a [Chart](<#Chart>).
+3. [File](<#File>) \- Generates data by reading a file from the component directory.
+4. [Command](<#Command>) \- Generates data by executing an user defined command.
+
+```go
+type Generator struct {
+    // Kind represents the kind of generator.  Must be Resources, Helm, or File.
+    Kind string `json:"kind" yaml:"kind" cue:"\"Resources\" | \"Helm\" | \"File\" | \"Command\""`
+    // Output represents a file for a Transformer or Artifact to consume.
+    Output FileOrDirectoryPath `json:"output" yaml:"output"`
+    // Resources generator. Ignored unless kind is Resources.  Resources are
+    // stored as a two level struct.  The top level key is the Kind of resource,
+    // e.g. Namespace or Deployment.  The second level key is an arbitrary
+    // InternalLabel.  The third level is a map[string]any representing the
+    // Resource.
+    Resources Resources `json:"resources,omitempty" yaml:"resources,omitempty"`
+    // Helm generator. Ignored unless kind is Helm.
+    Helm Helm `json:"helm,omitempty" yaml:"helm,omitempty"`
+    // File generator. Ignored unless kind is File.

+    // Command generator. Ignored unless kind is Command.
+    Command Command `json:"command,omitempty" yaml:"command,omitempty"`
+}
+```
+
+<a name="Helm"></a>
+## type Helm {#Helm}
+
+Helm represents a [Chart](<#Chart>) manifest [Generator](<#Generator>).
+
+```go
+type Helm struct {
+    // Chart represents a helm chart to manage.
+    Chart Chart `json:"chart" yaml:"chart"`
+    // Values represents values for holos to marshal into values.yaml when
+    // rendering the chart.  Values follow ValueFiles when both are provided.
+    Values Values `json:"values" yaml:"values"`
+    // ValueFiles represents hierarchial value files passed in order to the helm
+    // template -f flag.  Useful for migration from an ApplicationSet.  Use Values
+    // instead.  ValueFiles precede Values when both are provided.
+    ValueFiles []ValueFile `json:"valueFiles,omitempty" yaml:"valueFiles,omitempty"`

+    // KubeVersion represents the helm template --kube-version flag
+    KubeVersion string `json:"kubeVersion,omitempty" yaml:"kubeVersion,omitempty"`
+}
+```
+
+<a name="InternalLabel"></a>
+## type InternalLabel {#InternalLabel}
+
+InternalLabel is an arbitrary unique identifier internal to holos itself. The holos cli is expected to never write a InternalLabel value to rendered output files, therefore use a InternalLabel when the identifier must be unique and internal. Defined as a type for clarity and type checking.
+
+```go
+type InternalLabel string
+```
+
+<a name="Join"></a>
+## type Join {#Join}
+
+Join represents a [Transformer](<#Transformer>) using [bytes.Join](<https://pkg.go.dev/bytes#Join>) to concatenate multiple inputs into one output with a separator. Useful for combining output from [Helm](<#Helm>) and [Resources](<#Resources>) together into one [Artifact](<#Artifact>) when [Kustomize](<#Kustomize>) is otherwise unnecessary.
+

+## type Kustomization {#Kustomization}
+
+Kustomization represents a kustomization.yaml file for use with the [Kustomize](<#Kustomize>) [Transformer](<#Transformer>). Untyped to avoid tightly coupling holos to kubectl versions which was a problem for the Flux maintainers. Type checking is expected to happen in CUE against the kubectl version the user prefers.

+```
+
+<a name="Platform"></a>
+## type Platform {#Platform}
+
+Platform represents a platform to manage. A Platform specifies a [Component](<#Component>) collection and integrates the components together into a holistic platform. Holos iterates over the [Component](<#Component>) collection producing a [BuildPlan](<#BuildPlan>) for each, which holos then executes to render manifests.
+
+Inspect a Platform resource holos would process by executing:
+
+```
+cue export --out yaml ./platform
+```
+
+```go
+type Platform struct {
+    // APIVersion represents the versioned schema of this resource.
+    APIVersion string `json:"apiVersion" yaml:"apiVersion" cue:"string | *\"v1alpha6\""`

-
-Package v1alpha2 contains the core API contract between the holos cli and CUE configuration code. Platform designers, operators, and software developers use this API to write configuration in CUE which \`holos\` loads. The overall shape of the API defines imperative actions \`holos\` should carry out to render the complete yaml that represents a Platform.
-
-[Platform](<#Platform>) defines the complete configuration of a platform. With the holos reference platform this takes the shape of one management cluster and at least two workload cluster. Each cluster has multiple [HolosComponent](<#HolosComponent>) resources applied to it.
-
-Each holos component path, e.g. \`components/namespaces\` produces exactly one [BuildPlan](<#BuildPlan>) which in turn contains a set of [HolosComponent](<#HolosComponent>) kinds.
-
-The primary kinds of [HolosComponent](<#HolosComponent>) are:
-
-1. [HelmChart](<#HelmChart>) to render config from a helm chart.
-2. [KustomizeBuild](<#KustomizeBuild>) to render config from [Kustomize](<#Kustomize>)
-3. [KubernetesObjects](<#KubernetesObjects>) to render [APIObjects](<#APIObjects>) defined directly in CUE configuration.
-
-Note that Holos operates as a data pipeline, so the output of a [HelmChart](<#HelmChart>) may be provided to [Kustomize](<#Kustomize>) for post\-processing.

-
-<a name="APIObject"></a>
-## type APIObject {#APIObject}
-
-APIObject represents the most basic generic form of a single kubernetes api object. Represented as a JSON object internally for compatibility between tools, for example loading from CUE.
-
-```go
-type APIObject structpb.Struct
-```
-
-<a name="APIObjectMap"></a>
-## type APIObjectMap {#APIObjectMap}
-
-APIObjectMap represents the marshalled yaml representation of kubernetes api objects. Do not produce an APIObjectMap directly, instead use [APIObjects](<#APIObjects>) to produce the marshalled yaml representation from CUE data, then provide the result to [HolosComponent](<#HolosComponent>).

-type APIObjectMap map[Kind]map[Label]string
-```
-
-<a name="APIObjects"></a>
-## type APIObjects {#APIObjects}
-
-APIObjects represents Kubernetes API objects defined directly from CUE code. Useful to mix in resources to any kind of [HolosComponent](<#HolosComponent>), for example adding an ExternalSecret resource to a [HelmChart](<#HelmChart>).
-
-[Kind](<#Kind>) must be the resource kind, e.g. Deployment or Service.
-
-[Label](<#Label>) is an arbitrary internal identifier to uniquely identify the resource within the context of a \`holos\` command. Holos will never write the intermediate label to rendered output.

-<a name="BuildPlan"></a>
-## type BuildPlan {#BuildPlan}
-
-BuildPlan represents a build plan for the holos cli to execute. The purpose of a BuildPlan is to define one or more [HolosComponent](<#HolosComponent>) kinds. For example a [HelmChart](<#HelmChart>), [KustomizeBuild](<#KustomizeBuild>), or [KubernetesObjects](<#KubernetesObjects>).
-
-A BuildPlan usually has an additional empty [KubernetesObjects](<#KubernetesObjects>) for the purpose of using the [HolosComponent](<#HolosComponent>) DeployFiles field to deploy an ArgoCD or Flux gitops resource for the holos component.
-
-```go
-type BuildPlan struct {

-type FilePath string
-```
-
-<a name="HelmChart"></a>
-## type HelmChart {#HelmChart}
-
-HelmChart represents a holos component which wraps around an upstream helm chart. Holos orchestrates helm by providing values obtained from CUE, renders the output using \`helm template\`, then post\-processes the helm output yaml using the general functionality provided by [HolosComponent](<#HolosComponent>), for example [Kustomize](<#Kustomize>) post\-rendering and mixing in additional kubernetes api objects.
-
-```go

-Kind is a kubernetes api object kind. Defined as a type for clarity and type checking.
-
-```go
-type Kind string
-```
-
-<a name="KubernetesObjects"></a>
-## type KubernetesObjects {#KubernetesObjects}
-
-KubernetesObjects represents a [HolosComponent](<#HolosComponent>) composed of Kubernetes API objects provided directly from CUE using [APIObjects](<#APIObjects>).
-
-```go
-type KubernetesObjects struct {
-    HolosComponent `json:",inline"`
-    Kind           string `json:"kind" cue:"\"KubernetesObjects\""`
-}
-```
-
-<a name="Kustomize"></a>
-## type Kustomize {#Kustomize}
-
-Kustomize represents resources necessary to execute a kustomize build. Intended for at least two use cases:
-
-1. Process a [KustomizeBuild](<#KustomizeBuild>) [HolosComponent](<#HolosComponent>) which represents raw yaml file resources in a holos component directory.
-2. Post process a [HelmChart](<#HelmChart>) [HolosComponent](<#HolosComponent>) to inject istio, patch jobs, add custom labels, etc...
-
-```go
-type Kustomize struct {
-    // KustomizeFiles holds file contents for kustomize, e.g. patch files.
-    KustomizeFiles FileContentMap `json:"kustomizeFiles,omitempty"`

-    Kind           string `json:"kind" cue:"\"KustomizeBuild\""`
-}
-```
-
-<a name="Label"></a>
-## type Label {#Label}
-
-Label is an arbitrary unique identifier internal to holos itself. The holos cli is expected to never write a Label value to rendered output files, therefore use a [Label](<#Label>) then the identifier must be unique and internal. Defined as a type for clarity and type checking.
-
-A Label is useful to convert a CUE struct to a list, for example producing a list of [APIObject](<#APIObject>) resources from an [APIObjectMap](<#APIObjectMap>). A CUE struct using Label keys is guaranteed to not lose data when rendering output because a Label is expected to never be written to the final output.
-
-```go
-type Label string
-```
-
-<a name="Metadata"></a>
-## type Metadata {#Metadata}
-
-Metadata represents data about the holos component such as the Name.
-
-```go
-type Metadata struct {
-    // Name represents the name of the holos component.
-    Name string `json:"name"`
-    // Namespace is the primary namespace of the holos component.  A holos
-    // component may manage resources in multiple namespaces, in this case
-    // consider setting the component namespace to default.
-    //
-    // This field is optional because not all resources require a namespace,
-    // particularly CRD's and DeployFiles functionality.
-    // +optional
-    Namespace string `json:"namespace,omitempty"`
-}
-```
-
-<a name="Platform"></a>
-## type Platform {#Platform}
-
-Platform represents a platform to manage. A Platform resource informs holos which components to build. The platform resource also acts as a container for the platform model form values provided by the PlatformService. The primary use case is to collect the cluster names, cluster types, platform model, and holos components to build into one resource.
-
-```go
-type Platform struct {
-    // Kind is a string value representing the resource this object represents.
-    Kind string `json:"kind" cue:"\"Platform\""`
-    // APIVersion represents the versioned schema of this representation of an object.

-```
-
-<a name="PlatformSpec"></a>
-## type PlatformSpec {#PlatformSpec}
-
-PlatformSpec represents the specification of a Platform. Think of a platform specification as a list of platform components to apply to a list of kubernetes clusters combined with the user\-specified Platform Model.
-
-```go
-type PlatformSpec struct {
-    // Model represents the platform model holos gets from from the
-    // PlatformService.GetPlatform rpc method and provides to CUE using a tag.

-    Components []PlatformSpecComponent `json:"components"`
-}
-```
-
-<a name="PlatformSpecComponent"></a>
-## type PlatformSpecComponent {#PlatformSpecComponent}
-
-PlatformSpecComponent represents a holos component to build or render.
-
-```go
-type PlatformSpecComponent struct {
-    // Path is the path of the component relative to the platform root.
-    Path string `json:"path"`
-    // Cluster is the cluster name to provide when rendering the component.

-## type APIObject {#APIObject}
-
-APIObject represents the most basic generic form of a single kubernetes api object. Represented as a JSON object internally for compatibility between tools, for example loading from CUE.
-
-```go
-type APIObject structpb.Struct
-```
-
-<a name="APIObjectMap"></a>
-## type APIObjectMap {#APIObjectMap}
-
-APIObjectMap represents the marshalled yaml representation of kubernetes api objects. Do not produce an APIObjectMap directly, instead use [APIObjects](<#APIObjects>) to produce the marshalled yaml representation from CUE data, then provide the result to [Component](<#Component>).
-
-```go
-type APIObjectMap map[Kind]map[InternalLabel]string
-```
-
-<a name="APIObjects"></a>
-## type APIObjects {#APIObjects}
-
-APIObjects represents Kubernetes API objects defined directly from CUE code. Useful to mix in resources to any kind of [Component](<#Component>), for example adding an ExternalSecret resource to a [HelmChart](<#HelmChart>).
-
-[Kind](<#Kind>) must be the resource kind, e.g. Deployment or Service.
-
-[InternalLabel](<#InternalLabel>) is an arbitrary internal identifier to uniquely identify the resource within the context of a \`holos\` command. Holos will never write the intermediate label to rendered output.
-
-Refer to [Component](<#Component>) which accepts an [APIObjectMap](<#APIObjectMap>) field provided by [APIObjects](<#APIObjects>).
-
-```go
-type APIObjects struct {
-    APIObjects   map[Kind]map[InternalLabel]APIObject `json:"apiObjects"`
-    APIObjectMap APIObjectMap                         `json:"apiObjectMap"`
-}
-```
-
-<a name="BuildPlan"></a>
-## type BuildPlan {#BuildPlan}
-
-BuildPlan represents a build plan for the holos cli to execute. The purpose of a BuildPlan is to define one or more [Component](<#Component>) kinds. For example a [HelmChart](<#HelmChart>), [KustomizeBuild](<#KustomizeBuild>), or [KubernetesObjects](<#KubernetesObjects>).
-
-A BuildPlan usually has an additional empty [KubernetesObjects](<#KubernetesObjects>) for the purpose of using the [Component](<#Component>) DeployFiles field to deploy an ArgoCD or Flux gitops resource for the holos component.
-
-```go
-type BuildPlan struct {
-    Kind       string        `json:"kind" cue:"\"BuildPlan\""`

-## type FileContentMap {#FileContentMap}
-
-FileContentMap represents a mapping of file paths to file contents.

-
-```go
-type FilePath string
-```
-
-<a name="HelmChart"></a>
-## type HelmChart {#HelmChart}
-
-HelmChart represents a holos component which wraps around an upstream helm chart. Holos orchestrates helm by providing values obtained from CUE, renders the output using \`helm template\`, then post\-processes the helm output yaml using the general functionality provided by [Component](<#Component>), for example [Kustomize](<#Kustomize>) post\-rendering and mixing in additional kubernetes api objects.
-
-```go
-type HelmChart struct {

-    // EnableHooks enables helm hooks when executing the `helm template` command.
-    EnableHooks bool `json:"enableHooks" cue:"bool | *false"`
-}
-```
-
-<a name="InternalLabel"></a>
-## type InternalLabel {#InternalLabel}
-
-InternalLabel is an arbitrary unique identifier internal to holos itself. The holos cli is expected to never write a InternalLabel value to rendered output files, therefore use a [InternalLabel](<#InternalLabel>) when the identifier must be unique and internal. Defined as a type for clarity and type checking.
-
-A InternalLabel is useful to convert a CUE struct to a list, for example producing a list of [APIObject](<#APIObject>) resources from an [APIObjectMap](<#APIObjectMap>). A CUE struct using InternalLabel keys is guaranteed to not lose data when rendering output because a InternalLabel is expected to never be written to the final output.
-
-```go
-type InternalLabel string
-```
-
-<a name="Kind"></a>
-## type Kind {#Kind}
-
-Kind is a kubernetes api object kind. Defined as a type for clarity and type checking.
-
-```go
-type Kind string
-```
-
-<a name="KubernetesObjects"></a>
-## type KubernetesObjects {#KubernetesObjects}
-
-KubernetesObjects represents a [Component](<#Component>) composed of Kubernetes API objects provided directly from CUE using [APIObjects](<#APIObjects>).

-}
-```
-
-<a name="Kustomize"></a>
-## type Kustomize {#Kustomize}
-
-Kustomize represents resources necessary to execute a kustomize build. Intended for at least two use cases:
-
-1. Process a [KustomizeBuild](<#KustomizeBuild>) [Component](<#Component>) which represents raw yaml file resources in a holos component directory.
-2. Post process a [HelmChart](<#HelmChart>) [Component](<#Component>) to inject istio, patch jobs, add custom labels, etc...
-
-```go
-type Kustomize struct {
-    // KustomizeFiles holds file contents for kustomize, e.g. patch files.
-    KustomizeFiles FileContentMap `json:"kustomizeFiles,omitempty"`
-    // ResourcesFile is the file name used for api objects in kustomization.yaml
-    ResourcesFile string `json:"resourcesFile,omitempty"`
-}
-```
-
-<a name="KustomizeBuild"></a>
-## type KustomizeBuild {#KustomizeBuild}
-
-KustomizeBuild represents a [Component](<#Component>) that renders plain yaml files in the holos component directory using \`kubectl kustomize build\`.

-## type Metadata {#Metadata}
-
-Metadata represents data about the object such as the Name.
-
-```go
-type Metadata struct {
-    // Name represents the name of the holos component.
-    Name string `json:"name"`
-    // Namespace is the primary namespace of the holos component.  A holos
-    // component may manage resources in multiple namespaces, in this case
-    // consider setting the component namespace to default.
-    //
-    // This field is optional because not all resources require a namespace,
-    // particularly CRDs and DeployFiles functionality.
-    // +optional
-    Namespace string `json:"namespace,omitempty"`
-}
-```
-
-<a name="Platform"></a>
-## type Platform {#Platform}
-
-Platform represents a platform to manage. A Platform resource informs holos which components to build. The platform resource also acts as a container for the platform model form values provided by the PlatformService. The primary use case is to collect the cluster names, cluster types, platform model, and holos components to build into one resource.
-
-```go
-type Platform struct {
-    // Kind is a string value representing the resource this object represents.
-    Kind string `json:"kind" cue:"\"Platform\""`
-    // APIVersion represents the versioned schema of this representation of an object.

-}
-```
-
-<a name="PlatformSpec"></a>
-## type PlatformSpec {#PlatformSpec}
-
-PlatformSpec represents the specification of a Platform. Think of a platform specification as a list of platform components to apply to a list of kubernetes clusters combined with the user\-specified Platform Model.
-
-```go
-type PlatformSpec struct {
-    // Model represents the platform model holos gets from from the
-    // PlatformService.GetPlatform rpc method and provides to CUE using a tag.

-# Backstory
-
-Holos is a tool intended to lighten the burden of managing Kubernetes resources.  In 2020 we set out to develop a holistic platform composed from open source cloud native components.  We quickly became frustrated with how each of the major components packaged and distributed their software in a different way.  Many projects choose to distribute their software with Helm charts, while others provide plain yaml files and Kustomize bases.  The popular Kube Prometheus Stack project provides Jsonnet to render and update Kubernetes yaml manifests.

-# Concepts
-
-## Introduction
-
-This page is intended as a high level conceptual overview of the key concepts in
-Holos.  Refer to the [Core API](/docs/api/core/) for low level reference
-documentation.
-
-Holos is a tool built for platform engineers.  The Holos authors share three
-core values which guide our design decisions for the tool.
-
-1. Safety
-2. Ease of use
-3. Consistency
-
-Each of the following concepts are intended to support and strengthen one or
-more of these core values.  In this way we hope to lighten the burden carried by
-platform engineers.
-
-## Concepts
-
-- [Component](<#component>) - The primary building block in Holos, wraps a Helm chart, Kustomize base, or plain resources defined in CUE.
-- [Platform](<#platform>) - A collection of Components integrated into a software development platform.
-- [Model](<#model>) - Structured data included in the Platform specification, available to all Components.  For example, your organization's domain name.
-- [Rendering](<#rendering>) - Holos is a tool that makes the process of rendering Kubernetes manifests safer, easier, and consistent.

-## Component
-
-A Component is the primary building block when managing software with Holos.  A
-software project you wish to integrate into your platform, for example ArgoCD,
-is managed using one or more components.
-
-The primary Component kinds are:
-
-1. **HelmChart** to render config provided by Helm.
-2. **KustomizeBuild** to render config provided by Kustomize.
-3. **KubernetesObjects** to render config provided by CUE.
-
-Components are intended to integrate unmodified upstream software releases into
-your Platform.  In this way, the focus of a Component is more about the unique
-differentiating aspects of your platform than the upstream software contained in
-the Component.
-
-#### Example HelmChart Component
-
-The ArgoCD Component is a good example of a HelmChart component because it takes
-advantage of most of the key features that empower you to focus on the key
-differentiators of your unique platform.
-
-Take note of the following key points in this example ArgoCD Component:
-
-1. The Component wraps the ArgoCD Helm Chart in a way that's easy to upgrade and maintain over time.
-2. Newer Gateway API resources are mixed-in replacing the older Ingress resource included in the chart.
-3. Helm output is passed through Kustomize to configure secure mutual TLS encryption.
-4. Helm values are easier and safer to manipulate with CUE instead of text markup.
-5. Kustomize is easier and safer to manipulate with CUE instead of text markup.
-6. Platform data Model values are easily accessible, for example the OIDC issuer and the organizations's domain name.
-
-The Component wraps around the unmodified upstream ArgoCD helm chart
-providing easier upgrades as new versions are released.
-
-Note how the Component facilitates composition by allowing us to mix-in new
-functionality from the ecosystem without modifying the upstream chart.  The
-Platform this Component integrates with uses the new Gateway API, but the
-upstream helm chart does not yet support Gateway API.  See how the Resources
-field is used to mix-in a ReferenceGrant from the Gateway API without modifying
-the upstream helm chart.
-
-The Platform uses Istio to implement service to service encryption with mutual
-TLS.  The Component passes the Helm output to Kustomize to integrate with Istio.
-Kustomize is used to patch the argocd-server Deployment resource to inject the
-Istio sidecar for mutual TLS.
-
-Helm values are safer and easier to work with in CUE.  Note how you can modify
-helm values using well defined data instead of manipulating text yaml files.
-Similarly, the yaml files used for Kustomize are produced by CUE, which is again
-safer and easier because the Kustomize spec has been imported into CUE and is

-## Platform
-
-A Platform refers to all of the software and services integrated together to
-provide your organization's software development platform.  Holos is designed to
-manage all of the resources that compose your Platform using the [Kubernetes
-Resource Model][krm] (KRM).  Nearly all platforms are larger than Kubernetes
-itself.  For example, your developers likely need a GCS or S3 bucket to store
-data.  Holos takes advantage of Crossplane to manage resources in a consistent
-way.
-
-Holos defines a [Platform][Platform] object which collects multiple Components
-together along with organizational data defined by your Model.  Consider the
-following example, which is a Platform that manages a single Component which
-manages namespaces for each cluster in the Platform.
-
-```cue
-package holos
-
-import v1 "github.com/holos-run/holos/api/v1alpha2"
-
-v1.#Platform & {
-	metadata: name: "example"
-
-	spec: components: [{
-		path:    "components/namespaces"
-		cluster: "cluster1"
-	}]
-}
-```
-
-This platform is rendered by the command:
-
-```bash
-holos render platform ./platform
-```
-
-When Holos renders the platform, it iterates over each component, generates and
-executes a [BuildPlan][BuildPlan], then writes the fully rendered output of the
-component to the filesystem.  In this simple example, two files are produced:
-
-1. `deploy/clusters/cluster1/components/namespaces/namespaces.gen.yaml`
-2. `deploy/clusters/cluster1/gitops/namespaces.application.gen.yaml`
-
-The first file is a plain kubernetes manifest containing Namespace resources.
-The second file is an ArgoCD Application resource to deploy and manage the
-resources defined in the first file.
-
-## Model
-
-The Platform Model is where you store top-level data values used throughout
-multiple components in your Platform.  Your organization's domain name is a
-prime example of the kind of data stored in the Model.  Many components derive
-host names from your organization's domain name.  CUE makes this process safe,
-easy, and consistent.  For example:
-
-```cue
-hostname: "argocd.\(_Platform.Model.org.domain)"
-```
-
-When Holos renders a Platform, the model is loaded from a JSON file in the local
-filesystem.  The platform model file is intended to be committed to version
-control along with the rest of the Holos Platform and Component code.
-
-Holos additionally provides a web ui and form to make it easy to enter and
-validate top level configuration data.  You have complete control over the web
-form, it's rendered from JSON data defined by CUE.  Customizing the web form is
-an advanced topic, the key concept to take away is the Model is for top level,
-platform-wide data.  You control the shape and structure of the Model, and you
-have the ability to collect Model values using a simple web form.
-
-## Rendering
-
-Holos uses the Kubernetes resource model to manage configuration.  The Holos
-command line interface is the primary method you'll use to manage your platform.
-Holos uses CUE to provide a unified configuration model of the platform.  This
-unified configuration is built up from components packaged with Helm, Kustomize,
-CUE, or any other tool that can produce Kubernetes resource manifests as output.
-
-This process can be thought of as a data **rendering pipeline**.  The key
-concept is that Holos will always produce fully rendered output, but delegates
-the _application_ of the configuration to other tools like kubectl apply,
-ArgoCD, or Flux.
