You are implementing Task A14: create an `examples/basic/` directory with a minimal usage example, and run `terraform init -backend=false` + `terraform validate` to confirm the module compiles cleanly when consumed.

## What's already in place

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector`
- `versions.tf`, `variables.tf`, `outputs.tf`, `main.tf`, `templates/values.yaml.tpl` all done.
- All four VRL tests pass.
- `terraform validate` passes at the module root.
- `terraform` 1.9.0 is available via `mise exec terraform@1.9.0` (default `terraform` is older).

## Task Description

### Task A14: Examples directory + plan-only validation

**Files:**
- Create: `examples/basic/main.tf`
- Create: `examples/basic/versions.tf`
- Create: `examples/basic/README.md`

- [ ] **Step 1: Write `examples/basic/versions.tf`:**

```hcl
terraform {
  required_version = ">= 1.9.0"
  required_providers {
    kubernetes = { source = "hashicorp/kubernetes", version = ">= 2.20" }
    helm       = { source = "hashicorp/helm",       version = ">= 2.10" }
  }
}

provider "kubernetes" {
  config_path = "~/.kube/config"
}

provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
  }
}
```

NOTE: helm provider v3 changed the kubernetes config block syntax. If `terraform validate` complains about the `provider "helm"` block above, the v3 syntax is:

```hcl
provider "helm" {
  kubernetes = {
    config_path = "~/.kube/config"
  }
}
```

(equals sign instead of nested block). Try the original first, fall back to the v3 form if validate complains.

- [ ] **Step 2: Write `examples/basic/main.tf`:**

```hcl
module "vector" {
  source = "../.."

  chart_version              = "0.36.0"
  image_tag_version          = "0.40.0-distroless-libc"
  datadog_site               = "datadoghq.com"
  datadog_api_key_vault_path = "secret/data/datadog/api-key"

  external_secrets_cluster_store_name = "vault-cluster-store"
}
```

If the module's required-variables surface differs from this (e.g., a required variable was added in A12 that I missed), `terraform validate` will tell you. Add the missing required variables with reasonable example values.

- [ ] **Step 3: Write `examples/basic/README.md`:**

```markdown
# basic example

Minimal usage of the `vector` module. Used by CI for `terraform validate` /
`terraform plan` smoke testing — does not deploy.

\`\`\`bash
terraform init -backend=false
terraform validate
\`\`\`
```

(The triple-backticks need to be literal in the markdown — escape them in your tool input.)

- [ ] **Step 4: Run validation from inside `examples/basic/`:**

```bash
cd /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic
mise exec terraform@1.9.0 -- terraform init -backend=false
mise exec terraform@1.9.0 -- terraform validate
```

Expected: `Success! The configuration is valid.`

If validate fails:
- "Missing required argument" → add the required variable to `examples/basic/main.tf` with a reasonable example value.
- "Provider configuration not present" → adjust the helm provider block syntax (try the v3 equals-sign form).
- "Module not found" → verify the `source = "../.."` path resolves (should work given the directory layout).

Iterate until it's green.

- [ ] **Step 5: Run `terraform fmt -check -recursive`** from the module root — exit 0 expected (covers the new examples/ subdir).

## Constraints

- **DO NOT run any git commands.**
- **DO NOT** push, tag, open MRs.
- **DO NOT** run `terraform apply`. `terraform init -backend=false` and `terraform validate` are the only Terraform operations.
- **DO NOT** create snapshot test infrastructure.

## Spec / plan references

- Spec: `/Users/steve.briggs/projects/IAC/docs/superpowers/specs/2026-05-05-vector-redaction-design.md`
- Plan: `/Users/steve.briggs/projects/IAC/docs/superpowers/plans/2026-05-05-vector-redaction-pipeline.md` Task A14

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- Files created
- `terraform init -backend=false` result
- `terraform validate` result (must show "Success! The configuration is valid.")
- Any iteration: what failed first, what fix you applied
- `terraform fmt -check -recursive` result
- Self-review findings


I'll start by examining the existing module structure to understand the variables and configuration before creating the examples.

Now I have what I need. Let me create the examples directory and files. First, create the directory structure and all three files:


Create examples/basic directory


(Bash completed with no output)


Write

terraform {
  required_version = ">= 1.9.0"
  required_providers {
    kubernetes = { source = "hashicorp/kubernetes", version = ">= 2.20" }
    helm       = { source = "hashicorp/helm", version = ">= 2.10" }
  }
}

provider "kubernetes" {
  config_path = "~/.kube/config"
}

provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
  }
}


module "vector" {
  source = "../.."

  chart_version              = "0.36.0"
  image_tag_version          = "0.40.0-distroless-libc"
  datadog_site               = "datadoghq.com"
  datadog_api_key_vault_path = "secret/data/datadog/api-key"

  external_secrets_cluster_store_name = "vault-cluster-store"
}


# basic example

Minimal usage of the `vector` module. Used by CI for `terraform validate` /
`terraform plan` smoke testing — does not deploy.

```bash
terraform init -backend=false
terraform validate
```

Now run `terraform init -backend=false` from the examples/basic directory:


Bash

cd /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic && mise exec terraform@1.9.0 -- terraform init -backend=false 2>&1

Run terraform init with no backend in examples/basic

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.


Init succeeded. Helm v3.1.1 was installed, which means the `kubernetes {}` nested block syntax may fail — that's the v2 syntax. Let me run validate now to check:


cd /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic && mise exec terraform@1.9.0 -- terraform validate 2>&1

Run terraform validate in examples/basic


Error: Exit code 1
╷
│ Error: Unsupported block type
│
│   on versions.tf line 14, in provider "helm":
│   14:   kubernetes {
│
│ Blocks of type "kubernetes" are not expected here. Did you mean to define
│ argument "kubernetes"? If so, use the equals sign to assign it a value.
╵


As expected — helm v3 requires the equals-sign syntax. Applying the fix:


Edit

provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
  }
}

provider "helm" {
  kubernetes = {
    config_path = "~/.kube/config"
  }
}


The file /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic/versions.tf has been updated successfully. (file state is current in your context — no need to Read it back)


Bash

cd /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic && mise exec terraform@1.9.0 -- terraform validate 2>&1

Re-run terraform validate after helm provider syntax fix


Success! The configuration is valid.


Green. Now run `terraform fmt -check -recursive` from the module root:


mise exec terraform@1.9.0 -- terraform fmt -check -recursive 2>&1; echo "exit: $?"

Run terraform fmt check recursively from module root


exit: 0


All clean. Let me do a final sanity check on the files created:

Everything is in order. Here's the full report, Sir Charles of St Cheese.

---

**Status:** DONE

**Files created:**
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic/versions.tf`
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic/main.tf`
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/examples/basic/README.md`

**`terraform init -backend=false` result:** Success — resolved module from `../..`, downloaded `hashicorp/kubernetes v3.1.0` and `hashicorp/helm v3.1.1`.

**`terraform validate` result:** `Success! The configuration is valid.`

**Iteration — what failed first and the fix applied:**
The initial `versions.tf` used the helm v2 nested-block syntax (`kubernetes { ... }`). Because `terraform init` resolved helm to v3.1.1, validate immediately rejected it with "Blocks of type 'kubernetes' are not expected here." Applied the v3 equals-sign form (`kubernetes = { ... }`) as described in the task fallback, and validate passed on the second attempt.

**`terraform fmt -check -recursive` result:** Exit 0 — no formatting issues across the module root or the new examples subdirectory.

**Self-review findings:** No issues. The five required variables from `variables.tf` (`chart_version`, `image_tag_version`, `datadog_site`, `datadog_api_key_vault_path`, `external_secrets_cluster_store_name`) are all satisfied by `examples/basic/main.tf`. The `.terraform/` and `.terraform.lock.hcl` artifacts land inside `examples/basic/` and are covered by the module root's existing `.gitignore` patterns (verified by the `.gitignore` already present at the root).
