You are implementing Task A4: build the initial Vector Helm values template and a Terraform `templatefile`-based snapshot test that locks its rendered output.

## Task Description (verbatim from the plan)

### Task A4: Helm values template — sources and sinks (no transforms yet)

**Files:**
- Create: `templates/values.yaml.tpl`
- Create: `tests/snapshots/values-base.yaml`
- Create: `tests/render-snapshot.sh`

This is a TDD task — golden-file snapshot test for the rendered helm values. Add transforms incrementally in subsequent tasks.

- [ ] **Step 1: Write the golden file** at `tests/snapshots/values-base.yaml` representing what the values should look like with NO transforms in the pipeline (smoke-test baseline):

```yaml
role: Aggregator
replicas: 3
podAnnotations:
  reloader.stakater.com/auto: "true"
service:
  enabled: true
  type: ClusterIP
  ports:
    - name: otlp-grpc
      port: 4317
      protocol: TCP
    - name: otlp-http
      port: 4318
      protocol: TCP
env:
  - name: DATADOG_API_KEY
    valueFrom:
      secretKeyRef:
        name: vector-datadog
        key: api_key
resources:
  requests:
    cpu: 200m
    memory: 256Mi
  limits:
    cpu: "2"
    memory: 1Gi
customConfig:
  data_dir: /vector-data-dir
  api:
    enabled: true
    address: 127.0.0.1:8686
  sources:
    otlp_in:
      type: opentelemetry
      grpc:
        address: 0.0.0.0:4317
      http:
        address: 0.0.0.0:4318
  transforms: {}
  sinks:
    datadog_logs:
      type: datadog_logs
      inputs:
        - otlp_in.logs
      default_api_key: ${DATADOG_API_KEY}
      site: datadoghq.com
    datadog_traces:
      type: datadog_traces
      inputs:
        - otlp_in.traces
      default_api_key: ${DATADOG_API_KEY}
      site: datadoghq.com
    datadog_metrics:
      type: datadog_metrics
      inputs:
        - otlp_in.metrics
      default_api_key: ${DATADOG_API_KEY}
      site: datadoghq.com
```

- [ ] **Step 2: Write `templates/values.yaml.tpl`** that should produce the above when rendered with the default fixture inputs:

```yaml
role: Aggregator
replicas: ${replicas}
podAnnotations:
  reloader.stakater.com/auto: "true"
service:
  enabled: true
  type: ClusterIP
  ports:
    - name: otlp-grpc
      port: 4317
      protocol: TCP
    - name: otlp-http
      port: 4318
      protocol: TCP
env:
  - name: DATADOG_API_KEY
    valueFrom:
      secretKeyRef:
        name: vector-datadog
        key: api_key
resources:
  requests:
    cpu: ${requests_cpu}
    memory: ${requests_memory}
  limits:
    cpu: "${limits_cpu}"
    memory: ${limits_memory}
customConfig:
  data_dir: /vector-data-dir
  api:
    enabled: true
    address: 127.0.0.1:8686
  sources:
    otlp_in:
      type: opentelemetry
      grpc:
        address: 0.0.0.0:4317
      http:
        address: 0.0.0.0:4318
  transforms: {}
  sinks:
    datadog_logs:
      type: datadog_logs
      inputs:
        - otlp_in.logs
      default_api_key: $${DATADOG_API_KEY}
      site: ${datadog_site}
    datadog_traces:
      type: datadog_traces
      inputs:
        - otlp_in.traces
      default_api_key: $${DATADOG_API_KEY}
      site: ${datadog_site}
    datadog_metrics:
      type: datadog_metrics
      inputs:
        - otlp_in.metrics
      default_api_key: $${DATADOG_API_KEY}
      site: ${datadog_site}
```

Note: `$${...}` is the escape so Terraform's `templatefile()` emits literal `${...}` for Vector to expand at runtime.

- [ ] **Step 3: Write `tests/render-snapshot.sh`** — a small script that renders the template against the default fixture and diffs against the snapshot:

```bash
#!/usr/bin/env bash
set -euo pipefail
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
MODULE_DIR="$(dirname "$SCRIPT_DIR")"
RENDER_DIR="$(mktemp -d)"
trap 'rm -rf "$RENDER_DIR"' EXIT

cat > "$RENDER_DIR/main.tf" <<'EOF'
output "rendered" {
  value = templatefile("${path.module}/../../templates/values.yaml.tpl", {
    replicas        = 3
    requests_cpu    = "200m"
    requests_memory = "256Mi"
    limits_cpu      = "2"
    limits_memory   = "1Gi"
    datadog_site    = "datadoghq.com"
  })
}
EOF
ln -s "$MODULE_DIR/templates" "$RENDER_DIR/../templates"
( cd "$RENDER_DIR" && terraform init -backend=false >/dev/null && \
  terraform apply -auto-approve >/dev/null && \
  terraform output -raw rendered ) > "$SCRIPT_DIR/snapshots/.actual.yaml"

diff -u "$SCRIPT_DIR/snapshots/values-base.yaml" "$SCRIPT_DIR/snapshots/.actual.yaml"
echo "snapshot OK"
```

`chmod +x tests/render-snapshot.sh`.

- [ ] **Step 4: Run the snapshot test, expect it to pass.** If diff complains, **inspect the diff** and decide whether the template or the snapshot needs adjustment — they should align on first try if the template was written correctly, but small whitespace/quoting differences are common. Update whichever is wrong until they match.

```bash
./tests/render-snapshot.sh
```

## Context

- **Working directory:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector` — has `versions.tf`, `variables.tf`, `outputs.tf`, `.gitignore`, `README.md`.
- **Subsequent tasks** will incrementally add transforms (drop_audit, redact_emails_*) — keep that growth path in mind. The `transforms: {}` block in this baseline is intentionally empty.
- **Terraform `templatefile()` quirks to be aware of:**
  - The `terraform apply -auto-approve` in the script does not deploy any infrastructure — it's only evaluating an `output` expression. There are no resources defined, so this is purely a pure-function evaluation. This is safe and not a "deployment".
  - `${...}` inside the template is interpolated by Terraform.
  - `$${...}` becomes literal `${...}` in the rendered output (used for Vector's runtime env-var expansion of `${DATADOG_API_KEY}`).
  - YAML literal-style `key: value` is fine; YAML quoting matters when emitting numeric-looking strings (e.g. `cpu: "2"` must keep the quotes after rendering).
- **Common failure mode:** the script's heredoc uses a path `${path.module}/../../templates/values.yaml.tpl`. With the symlink trick this resolves to `<RENDER_DIR>/../templates/values.yaml.tpl`. Verify this works on macOS (BSD `ln`). If it doesn't, prefer copying the file or writing the path absolute.

- **Spec:** `/Users/steve.briggs/projects/IAC/docs/superpowers/specs/2026-05-05-vector-redaction-design.md` §4
- **Plan:** `/Users/steve.briggs/projects/IAC/docs/superpowers/plans/2026-05-05-vector-redaction-pipeline.md` Task A4

## Constraints

- **DO NOT run any git commands.** No `git add`, no `git commit`. The user handles git manually.
- **DO NOT push, tag, or open MRs.**
- **DO NOT run** `kubectl`, `helm install`, or anything else that mutates real clusters.
- The script's `terraform init -backend=false` and `terraform apply -auto-approve` against a temp-dir module with NO resources (just one output) is the only Terraform operation. It is read-only-equivalent — pure-function rendering. Permitted.

## Your Job

1. Write `templates/values.yaml.tpl` per the task spec.
2. Write `tests/snapshots/values-base.yaml` per the task spec.
3. Write `tests/render-snapshot.sh` per the task spec, make it executable.
4. Run `./tests/render-snapshot.sh`. Expect "snapshot OK".
5. If the script fails:
   - Read the diff carefully.
   - If the template has a bug (e.g. missing escape, extra whitespace, wrong placeholder), fix the **template**. The golden file represents desired output — don't bend the golden to match a buggy template. The exception is whitespace mismatches that are clearly cosmetic and safe to absorb into the golden.
   - If the script itself has a bug (path resolution, symlink issue, terraform quirk), fix the script.
   - Iterate until the test passes.
6. Self-review:
   - Are the three sinks correctly wired to `otlp_in.{logs,traces,metrics}` (the OTLP source's per-signal output streams)?
   - Is the `transforms: {}` baseline preserved (will be filled in by later tasks)?
   - Is the `$${DATADOG_API_KEY}` escape present in the template?
7. Report back. **Do not commit. Do not run any git commands.**

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- Files written and their line counts
- The `./tests/render-snapshot.sh` final stdout (must show "snapshot OK")
- Any iteration: what failed first, what fix you applied
- Self-review findings

Good. I have full context. Now I'll create the three files. Let me create the directories and files.


mkdir -p /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/templates && mkdir -p /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/snapshots

Now I need to write the render-snapshot.sh. The task spec uses a symlink trick that may be fragile on macOS with a temp dir. The spec notes the `${path.module}/../../templates/values.yaml.tpl` path will resolve via symlink. Let me think about this carefully.

The spec says: `ln -s "$MODULE_DIR/templates" "$RENDER_DIR/../templates"` — this symlinks `templates` into the parent of RENDER_DIR (which is `/tmp`). Then the terraform path `${path.module}/../../templates/` from RENDER_DIR would go `RENDER_DIR/../..` which is the parent of `/tmp`, not the module dir. That's broken.

The correct approach is to use the absolute path directly in the terraform config, avoiding the fragile symlink. I'll write the script to use the absolute MODULE_DIR path directly in the terraform template.


#!/usr/bin/env bash
set -euo pipefail
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
MODULE_DIR="$(dirname "$SCRIPT_DIR")"
RENDER_DIR="$(mktemp -d)"
trap 'rm -rf "$RENDER_DIR"' EXIT

cat > "$RENDER_DIR/main.tf" <<EOF
output "rendered" {
  value = templatefile("${MODULE_DIR}/templates/values.yaml.tpl", {
    replicas        = 3
    requests_cpu    = "200m"
    requests_memory = "256Mi"
    limits_cpu      = "2"
    limits_memory   = "1Gi"
    datadog_site    = "datadoghq.com"
  })
}
EOF

( cd "$RENDER_DIR" && terraform init -backend=false >/dev/null && \
  terraform apply -auto-approve >/dev/null && \
  terraform output -raw rendered ) > "$SCRIPT_DIR/snapshots/.actual.yaml"

diff -u "$SCRIPT_DIR/snapshots/values-base.yaml" "$SCRIPT_DIR/snapshots/.actual.yaml"
echo "snapshot OK"
