feat: add HumanUser auth primitive

[patrickleet]

What this changes

This adds the auth.hops.ops.com.ai/v1alpha1 HumanUser composite resource to auth-stack. It creates a Zitadel human identity declaratively while keeping generated organization and user IDs out of GitOps manifests.

It also updates Grant reference resolution so a Grant can consume the typed status exposed by the Hops HumanUser XR, while retaining support for raw Zitadel managed resources.

Why this belongs in auth-stack

HumanUser is an auth primitive, not an application-specific test fixture. Keeping it in the auth-stack package gives local and cloud environments the same API and lets downstream stacks compose users and grants without imperative Zitadel API calls.

Usage

Reference a managed Project to resolve its organization ID without committing a generated UUID:

apiVersion: auth.hops.ops.com.ai/v1alpha1
kind: HumanUser
metadata:
  name: alice
  namespace: default
spec:
  orgIdRef:
    name: platform
  firstName: Alice
  lastName: Example
  email: alice@example.com
  initialPasswordSecretRef:
    name: human-passwords
    key: alice
  providerConfigRef:
    name: default
    kind: ClusterProviderConfig

For adoption or an external organization, an explicit spec.orgId remains available. Existing users can be adopted with spec.humanUserId, and the initial password is accepted only through a namespaced Secret reference.

A Grant can reference the Hops XR directly:

spec:
  userIdRef:
    apiVersion: auth.hops.ops.com.ai/v1alpha1
    kind: HumanUser
    name: alice
  projectIdRef:
    name: platform
  roles: [user]

Implementation

• Adds the namespaced HumanUser XRD and pipeline composition.
• Resolves organization IDs through function-go-templating ExtraResources.
• Exposes typed status.userId, status.orgId, and status.loginName for downstream references.
• Preserves observed organization state during transient reference lookup gaps.
• Updates Grant composition and tests for Hops HumanUser status references.
• Adds examples and registers them in Make and CI validation.

Verification

• Package build completed successfully with DOCKER_HOST=unix:///Users/patrickleet/.dory/dory.sock.
• git diff --check passes.
• The local up test run was started with the Dory Docker context; function/package build completed, but the runner stalled while waiting for its test control plane and was interrupted. CI will run the full composition test matrix on this PR.

Release

After merge, publish the next auth-stack version (likely the next minor version because this adds a public API). Consumers that use HumanUser should pin that release; the currently published v1.8.x packages do not contain this API.

Summary by CodeRabbit

• New Features

  • Grant references now support HumanUser resources and resolve user and organization details automatically.
  • Added examples for both organization configuration options.

• Documentation

  • Updated documentation with HumanUser configuration and reference behavior.

• Validation

  • Added composition tests covering references, unresolved organizations, status fallback, and user adoption.

📝 Walkthrough

Walkthrough

The PR adds a namespaced HumanUser composite resource with organization resolution, provider-resource rendering, typed status, examples, and tests. Grant references now support typed Hops HumanUser status and shared ExtraResources resolution.

Changes

HumanUser composition

Layer / File(s)	Summary
HumanUser API contract and composition apis/humanusers/definition.yaml, apis/humanusers/composition.yaml, upbound.yaml, examples/humanusers/*	Defines the HumanUser XRD, organization-source validation, typed status, composition pipeline, function dependency, and explicit or referenced-organization examples.
HumanUser state and rendering functions/humanuser/*	Builds HumanUser state, resolves organization and observed values, renders the provider managed resource, and publishes userId, orgId, and loginName status.
Grant reference resolution apis/grants/composition.yaml, apis/grants/definition.yaml, functions/grant/*, tests/test-grant/main.k	Resolves Grant user and project references through shared ExtraResources context. Typed HumanUser status takes precedence over provider status fields.
Validation and project integration tests/test-humanuser/*, Makefile, .github/workflows/*, README.md, .gitignore	Adds HumanUser composition tests, registers examples for rendering and CI validation, documents the resource, and adds local or secret ignore rules.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 6ea7a

The PR adds HumanUser reference behavior, but the Grant API overview still describes all references as resolving from provider status, which may lead users to configure Hops HumanUser references incorrectly. The change is otherwise mergeable with owner awareness or a documentation follow-up.
