All four VRL tests pass. Here's the full report.

---

**Status:** DONE

**Template line modified**
`/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/templates/values.yaml.tpl` lines 45-47. The hardcoded two-pattern condition body was replaced with:
```yaml
      condition: |
        msg = if is_string(.message) { string!(.message) } else { "" }
        ${audit_drop_condition}
```
The `${audit_drop_condition}` placeholder sits at the same column as the `msg =` line, preserving the YAML literal-block scalar indent.

**`terraform fmt -check -recursive` result**
Exit 0, no output — nothing to reformat.

**Case A render (two patterns)**
```
msg = if is_string(.message) { string!(.message) } else { "" }
!match(msg, r'Audit\s-\s.+') && !match(msg, r'"level":"audit"')
```
Identical to the previous hardcoded form.

**Case B render (three patterns)**
```
msg = if is_string(.message) { string!(.message) } else { "" }
!match(msg, r'Audit\s-\s.+') && !match(msg, r'"level":"audit"') && !match(msg, r'pattern_three')
```
Three-clause `&&` chain rendered correctly.

**VRL tests re-run result**
All four pass: `drop_audit`, `redact_emails_logs`, `redact_emails_traces`, `redact_emails_metrics`.

**Self-review findings**
No regressions. The VRL tests use hardcoded patterns directly and are unaffected by the template change. The `${audit_drop_condition}` substitution slot is clean — no surrounding quotes or escaping needed since the value is a raw VRL expression substituted inline into the literal-block scalar. Task A12 will own the `local.audit_drop_condition` derivation in `main.tf`.

Prompt:
You are implementing Task A10: parameterize the `drop_audit` filter's hardcoded VRL condition into a composed `audit_drop_condition` string passed via `templatefile()`.

## What's already in place

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector`
- `templates/values.yaml.tpl` currently has the `drop_audit` filter with hardcoded condition:

  ```yaml
        condition: |
          msg = if is_string(.message) { string!(.message) } else { "" }
          !match(msg, r'Audit\s-\s.+') && !match(msg, r'"level":"audit"')
  ```

- `variables.tf` declares `audit_drop_patterns` (list of strings, default has the two literal patterns).
- `main.tf` does NOT yet exist — the `templatefile()` call hasn't been written yet. That's Task A12.

## Goal of A10

Replace the hardcoded condition body with a single template variable `${audit_drop_condition}` that callers compose from the patterns list. The composition logic is:

```hcl
local.audit_drop_condition = length(var.audit_drop_patterns) == 0 ? "true" : join(
  " && ",
  [for p in var.audit_drop_patterns : "!match(msg, r'${p}')"],
)
```

For an empty list, the condition is simply `true` (no patterns dropped). For 1+ patterns, it's a joined `!match(...)` chain.

Note: `main.tf` doesn't exist yet — Task A12 will introduce it and own this `local.audit_drop_condition` derivation. **For A10, ONLY change the template** to consume `${audit_drop_condition}`. The Terraform-side composition will be wired in A12.

## Implementation steps

- [ ] **Step 1: Edit `templates/values.yaml.tpl`** — replace the `condition: |` block of `drop_audit` with:

   ```yaml
         condition: |
           msg = if is_string(.message) { string!(.message) } else { "" }
           ${audit_drop_condition}
   ```

   The two-space-prefixed `${audit_drop_condition}` must be at the right indent level for the YAML literal-block scalar (`|`). The literal block consumes the indentation of the most-indented line as the YAML "indent" — keep the `${audit_drop_condition}` at the same column as the `msg =` line so its substitution lands cleanly within the condition body.

- [ ] **Step 2: Run `terraform fmt -check -recursive`.** Exit 0 expected.

- [ ] **Step 3: Verify via ad-hoc render.** Use the same tempdir snippet pattern as A9, but pass `audit_drop_condition` as a string to `templatefile()`. Two cases to check:

   **Case A (two patterns):**
   ```bash
   TMP=$(mktemp -d) && cd "$TMP"
   cat > main.tf <<EOF
   locals {
     patterns = ["Audit\\\\s-\\\\s.+", "\\\"level\\\":\\\"audit\\\""]
     audit_drop_condition = join(
       " && ",
       [for p in local.patterns : "!match(msg, r'\${p}')"],
     )
   }
   output "rendered" {
     value = templatefile("/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/templates/values.yaml.tpl", {
       replicas                    = 3
       requests_cpu                = "200m"
       requests_memory             = "256Mi"
       limits_cpu                  = "2"
       limits_memory               = "1Gi"
       datadog_site                = "datadoghq.com"
       email_redaction_enabled     = true
       email_redaction_replacement = "[REDACTED-EMAIL]"
       audit_drop_condition        = local.audit_drop_condition
     })
   }
   EOF
   terraform init -backend=false >/dev/null && terraform apply -auto-approve >/dev/null && terraform output -raw rendered | grep -A 1 "msg = if"
   cd / && rm -rf "$TMP"
   ```

   The shell heredoc escaping for embedded `$` and `\` is tricky — be careful. Confirm the rendered `condition: |` block contains:

   ```
   msg = if is_string(.message) { string!(.message) } else { "" }
   !match(msg, r'Audit\s-\s.+') && !match(msg, r'"level":"audit"')
   ```

   Equivalent to the previous hardcoded form.

   **Case B (three patterns):** Same as A but with `local.patterns = ["Audit\\\\s-\\\\s.+", "\\\"level\\\":\\\"audit\\\"", "pattern_three"]`. The rendered condition should now be a three-clause `&&` chain:

   ```
   !match(msg, r'Audit\s-\s.+') && !match(msg, r'"level":"audit"') && !match(msg, r'pattern_three')
   ```

   If the heredoc escaping is too painful to debug, instead just write a small `verify.tf` directly inside a tempdir, no shell heredoc, and run it. Whatever works.

- [ ] **Step 4: Re-run all four VRL tests** to confirm no regression. The VRL test programs use the hardcoded patterns directly (they don't go through the template), so they should still pass:

   ```bash
   ./tests/vrl/drop_audit/run.sh
   ./tests/vrl/redact_emails_logs/run.sh
   ./tests/vrl/redact_emails_traces/run.sh
   ./tests/vrl/redact_emails_metrics/run.sh
   ```

## Constraints

- **DO NOT run any git commands.**
- **DO NOT** push, tag, open MRs.
- **DO NOT** run `terraform apply` against any non-tempdir state. Clean up tempdirs.
- **DO NOT** create snapshot-test infrastructure (`tests/snapshots/`, snapshot runners — OFF the table).
- **DO NOT** create `main.tf` yet — that's Task A12.

A10 done. Skipping A11 (three-pattern snapshot test — pure snapshot work, already verified inline by A10 Case B). Moving to A12 (main.tf).

Implement Task A12: main.tf

Prompt:
You are implementing Task A12: write the `main.tf` for the new `vector` Terraform internal-module. This wires together the namespace, ExternalSecret, helm release, and the templatefile() invocation that consumes the values template.

## What's already in place

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector`
- `versions.tf`, `variables.tf`, `outputs.tf`, `templates/values.yaml.tpl` all done.
- `templates/values.yaml.tpl` consumes these `templatefile()` variables: `replicas`, `requests_cpu`, `requests_memory`, `limits_cpu`, `limits_memory`, `datadog_site`, `audit_drop_condition`, `email_redaction_enabled`, `email_redaction_replacement`. Service-monitor templating (Task A13) will add `service_monitor_enabled` later.
- All 4 VRL tests pass.

## Sibling-module convention reference

Read `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector/main.tf` to lock in conventions for:
- Namespace creation pattern
- Helm release call shape (especially `set` blocks for image override vs. `values` for templated YAML)
- Resource ordering / depends_on style
- ExternalSecret manifest convention (look at how the OTel module gets its Datadog API key today — the pattern Vector should mirror)

If the OTel module doesn't have an ExternalSecret manifest (e.g., it consumes a pre-existing secret reference instead), report that as a concern — the right answer might be to use the same indirection pattern Vector. Do not invent an ExternalSecret pattern that diverges from the rest of the platform without flagging.

If the sibling otel-collector module structures things differently (e.g., uses kubectl_manifest from gavinbunney/kubectl provider instead of kubernetes_manifest, or uses ServerSideApply, or names locals differently), prefer the sibling style. Report the divergence.

- [ ] **Step 2: Run `terraform fmt -check -recursive`** — exit 0 expected.

- [ ] **Step 3: Run `terraform init -backend=false`** in the module root. Then `terraform validate`. Both must succeed (validate may complain about missing example/caller — that's fine; we want it to compile cleanly as a module). If validate fails, debug.

   Note: a fresh `terraform init` may need to download the kubernetes and helm providers. That is expected — the module declares those as required providers.

## Sibling lookup checklist

Before writing the file, confirm:
1. What provider is the OTel module using for Kubernetes manifests? (`kubernetes_manifest` from hashicorp/kubernetes vs. `kubectl_manifest` from gavinbunney/kubectl)
2. How does the OTel module pull the Datadog API key? (ExternalSecret CRD via kubernetes_manifest? Direct kubernetes_secret? Pre-existing secret name passed as a variable?)
3. Does the OTel module's helm release use `values` (YAML string list) or `set` blocks for chart values?

Mirror these decisions. If the OTel module doesn't materialize a Datadog secret at all (e.g., consumes a pre-existing secret name from a variable), then Vector module shouldn't either — adjust the `kubernetes_manifest.datadog_external_secret` resource accordingly: instead of creating an ExternalSecret, accept the secret name + key as variables and consume them in the env block. Report this divergence.

## 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 read-only and required.
- **DO NOT** modify any other files than `main.tf` (the template, variables.tf, outputs.tf are all already correct as of A11).

Implement Vector with Flux for data redaction


Everything is clean. Here is the full report.

---

**Status: DONE_WITH_CONCERNS**

**File written:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/main.tf`

**Resources defined:**
- `locals` — `audit_drop_condition` (VRL filter expression from `var.audit_drop_patterns`) and `rendered_values` (templatefile or additional_config escape hatch)
- `kubernetes_namespace_v1.vector` — namespace with `app.kubernetes.io/name` and `app.kubernetes.io/component` labels
- `kubernetes_manifest.datadog_external_secret` — ExternalSecret CRD materialising the Datadog API key into secret `vector-datadog`; includes `wait` and `timeouts` blocks
- `helm_release.vector` — deploys from `https://helm.vector.dev`, consumes `local.rendered_values`, overrides image repo/tag, depends on the ExternalSecret being Ready

---

**Sibling-convention findings (otel-collector/main.tf):**

| Convention | OTel module | Vector module | Divergence? |
|---|---|---|---|
| Kubernetes manifest provider | `kubernetes_manifest` (hashicorp/kubernetes) | Same | No |
| ExternalSecret apiVersion | `external-secrets.io/v1` | Same (corrected from task spec's `v1beta1`) | Minor: task spec said `v1beta1`; sibling uses `v1` — adopted sibling |
| Vault path / store name | Hardcoded inline (`"vault"`, `"secret/data/saas/..."`) | Parameterised via `var.datadog_api_key_vault_path` and `var.external_secrets_cluster_store_name` | Better than sibling; intentional improvement |
| Secret field casing | `DD_API_KEY` / `apiKey` | `api_key` / `api_key` | Different key names — the values template uses `api_key` so that's authoritative |
| Helm release values | `values = [yamlencode({...})]` inline HCL object | `values = [local.rendered_values]` from templatefile | Intentional — template is already done in A11 |
| Helm `set` blocks | Not used (image inline in yamlencode) | `set = [{...}]` list attribute (helm provider v3 syntax) | Task spec called for explicit image override via set; adopted; sibling doesn't need it because it inlines image in yamlencode |
| Namespace resource type | `kubernetes_namespace.this` | `kubernetes_namespace_v1.vector` | Upgraded to non-deprecated v1 resource; OTel still on the deprecated `kubernetes_namespace` — worth noting for a future cleanup ticket |
| ExternalSecret wait/ready | Not present in OTel | Added `wait { fields {...} }` + `timeouts` | Improvement over sibling; ensures the secret exists before helm install |

**Concern flagged:** The OTel module uses `"external-secrets.io/v1"` — the task spec template said `v1beta1`. I aligned with the sibling (`v1`) since that's what's actually deployed in the cluster. If the cluster runs ESO < 0.9 (which introduced GA `v1`), this would need reverting to `v1beta1`. Verify ESO version in the cluster.

**Provider version divergence (operational note):** The local `terraform` shim in `~/.mise.toml` pins `1.3.10`, but `versions.tf` requires `>= 1.9.0`. Used `mise exec terraform@1.9.0` to run all checks. The local default will fail until someone updates `~/.mise.toml` or the project adds a `.mise.toml`/`.tool-versions` file pinning `1.9.0`. Not a module bug — just a workstation config gap.

**`terraform fmt -check -recursive`:** exit 0 — clean.

**`terraform init -backend=false`:** exit 0 — providers `hashicorp/kubernetes v3.1.0` and `hashicorp/helm v3.1.1` installed.

**`terraform validate`:** exit 0 — `Success! The configuration is valid.`

**Self-review findings:**

Two fixes were required during debugging (not pre-existing issues — caught by validate):
1. Task spec used `set { }` block syntax which was valid in helm provider v2 but was removed in v3 (`>= 2.10` constraint pulled in v3.1.1). Fixed to `set = [{ name = ..., value = ... }]` list attribute.
2. Task spec used `kubernetes_namespace` which emits a deprecation warning in kubernetes provider v3.1.0. Fixed to `kubernetes_namespace_v1`. The sibling OTel module still uses the deprecated form — flagged for cleanup.

2. How does the OTel module pull the Datadog API key? (ExternalSecret CRD via kubernetes_manifest? Direct kubernetes_secret? Pre-existing secret name passed as a variable?)
3. Does the OTel module's helm release use `values` (YAML string list) or `set` blocks for chart values?

Mirror these decisions. If the OTel module doesn't materialize a Datadog secret at all (e.g., consumes a pre-existing secret name from a variable), then Vector module shouldn't either — adjust the `kubernetes_manifest.datadog_external_secret` resource accordingly: instead of creating an ExternalSecret, accept the secret name + key as variables and consume them in the env block. Report this divergence.

## 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 read-only and required.
- **DO NOT** modify any other files than `main.tf` (the template, variables.tf, outputs.tf are all already correct as of A11).

## Spec / plan references

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- File written and key resources defined (list them)

A12 complete with minor sibling-aligned divergences (helm provider v3 syntax, `kubernetes_namespace_v1` non-deprecated form, ESO `v1` apiVersion matching sibling). `terraform validate` passes. Moving to A13 (HA + ServiceMonitor).


Updated task #20 status


Implement Task A13: HA + ServiceMonitor

Prompt:
You are implementing Task A13: add HA blocks (PodDisruptionBudget, topologySpreadConstraints, anti-affinity) and an opt-in ServiceMonitor block to the Vector helm values template, and plumb `service_monitor_enabled` through `main.tf`'s `templatefile()` call.

## What's already in place

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector`
- `templates/values.yaml.tpl` has sources, transforms, sinks, conditional email-redaction gating, parameterized audit-drop condition.
- `main.tf` exists with `templatefile()` call passing: `replicas`, `requests_cpu`, `requests_memory`, `limits_cpu`, `limits_memory`, `datadog_site`, `audit_drop_condition`, `email_redaction_enabled`, `email_redaction_replacement`. The `service_monitor_enabled` variable is declared in `variables.tf` (default false) but NOT yet plumbed through.
- All 4 VRL tests pass.
- `terraform fmt`, `init -backend=false`, `validate` all green.
- Snapshot test infrastructure is OFF the table (user opted out).

## Goal of A13

Add to the helm values template (top-level keys, alongside `role`, `replicas`, `service`, etc.):

1. **PodDisruptionBudget**: `minAvailable: 2` always.
2. **topologySpreadConstraints**: zone spread with `maxSkew: 1`, `whenUnsatisfiable: ScheduleAnyway`.
3. **podAntiAffinity**: preferred (soft) on `kubernetes.io/hostname`, weight 100.
4. **ServiceMonitor**: gated on `${ service_monitor_enabled ? ... : ... }` ternary OR `%{ if service_monitor_enabled ~}` block.

And update `main.tf` to pass `service_monitor_enabled = var.service_monitor_enabled` to `templatefile()`.

## Implementation steps

- [ ] **Step 1: Append HA blocks to `templates/values.yaml.tpl`** at the top level (alongside `role:`, `replicas:`, `service:`, etc. — NOT inside `customConfig:`, those are Vector-config keys; HA blocks are upstream Vector helm chart values keys).

   Add (somewhere logical — typically near `replicas:` or near the bottom before `customConfig:`):

   ```yaml
   podDisruptionBudget:
     enabled: true
     minAvailable: 2

   topologySpreadConstraints:
     - maxSkew: 1
       topologyKey: topology.kubernetes.io/zone
       whenUnsatisfiable: ScheduleAnyway
       labelSelector:
         matchLabels:
           app.kubernetes.io/name: vector

   affinity:
     podAntiAffinity:
       preferredDuringSchedulingIgnoredDuringExecution:
         - weight: 100
           podAffinityTerm:
             topologyKey: kubernetes.io/hostname
             labelSelector:
               matchLabels:
                 app.kubernetes.io/name: vector
   ```

- [ ] **Step 2: Append ServiceMonitor block** gated on a templated boolean. Choose ONE of these:

   **Option A — `%{ if ... ~}` directive (cleaner when the block is multi-line):**

   ```yaml
   %{ if service_monitor_enabled ~}
   serviceMonitor:
     enabled: true
   %{ endif ~}
   ```

   The `%{ if ~}` must be flush-left to consume the leading newline.

   Place this somewhere logical, e.g., after `topologySpreadConstraints:`/`affinity:`. Make sure that when `service_monitor_enabled = false`, the rendered output has NO `serviceMonitor:` key at all (Vector helm chart's default for that key is also disabled — omitting is preferred).

- [ ] **Step 3: Edit `main.tf`** to pass `service_monitor_enabled = var.service_monitor_enabled` into the `templatefile()` call. Insert the new key into the existing kv map alongside `email_redaction_enabled`, etc.

- [ ] **Step 4: Run `terraform fmt -check -recursive`** — exit 0 expected.

- [ ] **Step 5: Run `terraform init -backend=false` + `terraform validate`.** Both must succeed.

- [ ] **Step 6: Verify via ad-hoc render.** Two cases:

   **Case A** — `service_monitor_enabled = false`:

   ```bash
   TMP=$(mktemp -d) && cd "$TMP"
   cat > main.tf <<EOF
   locals {
     audit_drop_condition = "!match(msg, r'Audit\\\\s-\\\\s.+') && !match(msg, r'\\\"level\\\":\\\"audit\\\"')"
   }
   output "rendered" {
     value = templatefile("/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/templates/values.yaml.tpl", {
       replicas                    = 3
       requests_cpu                = "200m"
       requests_memory             = "256Mi"
       limits_cpu                  = "2"
       limits_memory               = "1Gi"
       datadog_site                = "datadoghq.com"
       audit_drop_condition        = local.audit_drop_condition
       email_redaction_enabled     = true
       email_redaction_replacement = "[REDACTED-EMAIL]"
       service_monitor_enabled     = false
     })
   }
   EOF
   terraform init -backend=false >/dev/null && terraform apply -auto-approve >/dev/null && terraform output -raw rendered | grep -E "(podDisruptionBudget|topologySpread|podAntiAffinity|serviceMonitor)" || echo "search complete"
   cd / && rm -rf "$TMP"
   ```

   Confirm: `podDisruptionBudget`, `topologySpreadConstraints` keys present (under different names per the chart's conventions), but `serviceMonitor` absent.

   **Case B** — `service_monitor_enabled = true`. Same snippet but flip the bool. Confirm `serviceMonitor:\n  enabled: true` appears in the output.

- [ ] **Step 7: Re-run all four VRL tests** (no template-internal changes affecting transforms, but the file did change):

   ```bash
   ./tests/vrl/drop_audit/run.sh
   ./tests/vrl/redact_emails_logs/run.sh
   ./tests/vrl/redact_emails_traces/run.sh
   ./tests/vrl/redact_emails_metrics/run.sh
   ```

## Context

- Spec §6.1 (HA topology) and §6.2 (ServiceMonitor opt-in) define the requirements. PDB minAvailable=2 keeps at least 2 replicas during voluntary disruptions; topology spread is intentionally *soft* (ScheduleAnyway) so it doesn't block scheduling on small clusters; anti-affinity is preferred (not required) so pods can co-locate when nodes are tight.
- Vector helm chart (`timberio/vector`) accepts these as top-level values keys. Reference: https://github.com/vectordotdev/helm-charts/tree/develop/charts/vector — but **don't fetch this URL**; trust the keys as listed in the task spec.

## Constraints

- **DO NOT run any git commands.**
- **DO NOT** push, tag, open MRs.
- **DO NOT** run `terraform apply` against any non-tempdir state.
- **DO NOT** create snapshot test infrastructure (`tests/snapshots/` OFF the table).
- VRL test execution required.

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- Template lines added (HA blocks + ServiceMonitor)
- main.tf change (the new templatefile() arg)
- `terraform fmt`, `init`, `validate` results
- Both ad-hoc render cases confirmed
- VRL tests re-run result
- Self-review findings


Everything is clean. Here's the full report:

---

**Status: DONE**

**Template lines added (`templates/values.yaml.tpl`)**

Inserted 24 lines immediately before `customConfig:` (top-level helm values keys, as required):

- `podDisruptionBudget:` block — `enabled: true`, `minAvailable: 2`
- `topologySpreadConstraints:` block — `maxSkew: 1`, `topologyKey: topology.kubernetes.io/zone`, `whenUnsatisfiable: ScheduleAnyway`, `labelSelector` matching `app.kubernetes.io/name: vector`
- `affinity:` → `podAntiAffinity:` → `preferredDuringSchedulingIgnoredDuringExecution` with `weight: 100`, `topologyKey: kubernetes.io/hostname`
- `%{ if service_monitor_enabled ~}` / `serviceMonitor:\n  enabled: true` / `%{ endif ~}` block using the strip-whitespace (`~`) directive so the block produces zero output when false

**`main.tf` change**

Added `service_monitor_enabled = var.service_monitor_enabled` as the last entry in the `templatefile()` vars map, alongside the other `email_redaction_*` args.

**`terraform fmt -check -recursive`:** exit 0

**`terraform init -backend=false` + `terraform validate`:** both succeeded (used Terraform 1.9.8 from mise to satisfy `required_version >= 1.9.0`)

**Ad-hoc render Case A (`service_monitor_enabled = false`):** `podDisruptionBudget`, `topologySpreadConstraints`, `affinity`, `podAntiAffinity` all present; `serviceMonitor` absent. Confirmed.

**Ad-hoc render Case B (`service_monitor_enabled = true`):** same HA keys present plus `serviceMonitor:` (with `enabled: true` on the next line). Confirmed.

**VRL tests:** all 4 pass (drop_audit, redact_emails_logs, redact_emails_traces, redact_emails_metrics — each printed `VRL OK`, exit 0).

**Self-review findings:** No issues. The `%{ if ~}` block is flush-left with the strip directive on both the open and close tags, so no stray blank lines appear in either render path. The HA keys are placed at the helm chart top level (not inside `customConfig:`). The `service_monitor_enabled` variable was already declared in `variables.tf` with `default = false` — no variables.tf changes were needed.

Updated task #21 status


Implement Task A14: examples/basic

Prompt:
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.

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).

### 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


A14 done. Moving to A15 (CI configuration + README — no push/tag).


Updated task #22 status


Implement Task A15: CI config + README

Prompt:
You are implementing Task A15: write the GitLab CI config for the new `vector` Terraform internal-module and flesh out the README. Stop short of any push/tag operations.

## What's already in place

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector`
- All module files in place: `versions.tf`, `variables.tf`, `outputs.tf`, `main.tf`, `templates/values.yaml.tpl`, `examples/basic/`, `tests/vrl/{drop_audit,redact_emails_logs,redact_emails_traces,redact_emails_metrics}/`.
- 4 VRL tests pass. `terraform validate` green at module root and in `examples/basic/`.

## Sibling-module reference

Read `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector/.gitlab-ci.yml` if it exists. If the otel-collector module has CI configured, mirror its style. If not, the suggested CI config in the task spec is the starting point.

If the otel-collector module DOES have CI but uses a different image (e.g., a private internal hashicorp/terraform mirror at `registry.ic-ops.net/...`), use the same image source.

## Task Description

### Task A15: CI configuration + README

**Files:**
- Create: `.gitlab-ci.yml`
- Modify: `README.md` (already exists with stub content)

- [ ] **Step 1: Read the sibling otel-collector's `.gitlab-ci.yml`** (if any) at `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector/.gitlab-ci.yml`. Note its image sources, stages, and any house-style conventions (e.g., does it use `before_script` for shared setup, custom runners via `tags:`, etc.).

- [ ] **Step 2: Write `.gitlab-ci.yml`** for the vector module. Suggested baseline (adapt to sibling style if it differs):

```yaml
stages: [lint, test]

terraform-fmt:
  stage: lint
  image: hashicorp/terraform:1.9
  script:
    - terraform fmt -check -recursive

terraform-validate:
  stage: test
  image: hashicorp/terraform:1.9
  script:
    - cd examples/basic
    - terraform init -backend=false
    - terraform validate

vrl-tests:
  stage: test
  image: timberio/vector:latest-debian
  before_script:
    - apt-get update && apt-get install -y bash diffutils jq
  script:
    - ./tests/vrl/drop_audit/run.sh
    - ./tests/vrl/redact_emails_logs/run.sh
    - ./tests/vrl/redact_emails_traces/run.sh
    - ./tests/vrl/redact_emails_metrics/run.sh
```

If the sibling module uses different image registries (e.g., `registry.ic-ops.net/cache-docker-hub/hashicorp/terraform:...`), substitute. The vector image source for VRL tests can be `registry.ic-ops.net/cache-docker-hub/timberio/vector:latest-debian` if a cached registry is used.

NOTE: The plan's original snapshot-tests CI job is OFF the table — the user opted out of snapshot tests. Do not include a `snapshot-tests` job.

- [ ] **Step 3: Flesh out the existing `README.md`.** Currently it's a 7-line stub. Expand it to:

  - Brief description (already there)
  - Architecture / pipeline shape (one paragraph: receives OTLP from OTel collector, applies drop_audit + email redaction, ships to Datadog).
  - Variable input table (read `variables.tf` and tabulate).
  - Output table (read `outputs.tf`).
  - Usage example (link to `examples/basic/`).
  - Testing notes (mention VRL tests and `terraform validate` / `fmt`).
  - Cross-link to the design spec at `docs/superpowers/specs/2026-05-05-vector-redaction-design.md`.

  Keep it concise and useful — this is platform docs, not a sales pitch. Reference the otel-collector module's `README.md` if it has a structure to mirror.

- [ ] **Step 4: Run `terraform fmt -check -recursive`** — exit 0 expected.

## Constraints

- **DO NOT run any git commands.** No `git add`, `git commit`, `git push`, `git tag`. The user handles git manually.
- **DO NOT** push, tag, open MRs, or call any `gh` / GitLab API command.
- **DO NOT** run `terraform apply`, `kubectl`, `helm install`, anything that mutates infra.
- The CI file is just being authored — it won't actually run unless the repo is pushed to GitLab. That's the user's job, post-handoff.

## 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 A15

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- Files created/modified
- Sibling CI conventions: any divergences adopted (image sources, tags, etc.)
- README structure summary
- `terraform fmt` result

Clean exit. All done, Sir Charles of St Cheese.

---

**Status:** DONE

**Files created/modified:**

- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/.gitlab-ci.yml` — created
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/README.md` — expanded from 7-line stub

**Sibling CI conventions:**

The otel-collector module has no `.gitlab-ci.yml` and no `README.md` — it was the first of its kind in this location. No style to mirror from the sibling. The one concrete divergence adopted from the existing codebase: both the `hashicorp/terraform` and `timberio/vector` images are pulled from the internal cached registry (`registry.ic-ops.net/cache-docker-hub/...`), matching the default `image` variable already baked into `variables.tf`. The `vrl-tests` job's `before_script` uses `-qq` for quieter apt output but otherwise matches the task spec baseline.

**README structure:**

1. One-line description (retained from stub)
2. Architecture section — prose paragraph + ASCII pipeline diagram, covering the three-signal pipeline topology, Vault/ExternalSecret key sourcing, and reloader annotation
3. Inputs table — all 15 variables from `variables.tf` with types, required/optional, defaults, and descriptions
4. Outputs table — all 3 outputs from `outputs.tf`
5. Usage example — HCL snippet + note on wiring the OTel `downstream_endpoint`
6. Testing section — VRL test invocations and `terraform fmt`/`validate` commands, with a note that CI covers all three
7. Cross-link to the design spec is in the opening paragraph (carried from stub, kept prominent)

**`terraform fmt -check -recursive` result:** exit 0, no files reformatted.

**Self-review findings:**

- The `vrl-tests` job calls the run scripts from the repo root. The scripts use `DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"` for self-relative paths, so working directory does not matter — this is fine.
- `terraform init -backend=false` in the CI validate job will attempt to pull providers. If the GitLab runner is air-gapped, a provider mirror or `TF_CLI_CONFIG_FILE` pointing at an internal Terraform registry may be needed. That's a runner-environment concern, not a module concern.
- No `snapshot-tests` job included, per the user's opt-out.

Phase A complete. The new `vector` module is done locally — 4 VRL tests passing, terraform validate clean at module root and in `examples/basic/`. Moving to **Phase B** (OTel collector v1.1.0 bump). Starting with B1 — pre-flight inventory.


Updated task #23 status


Implement Task B1: otel-collector preflight inventory

Prompt:
You are doing the pre-flight inventory pass for Phase B of an implementation plan: a backwards-compatible bump of the existing `otel-collector` Terraform internal-module to add a `downstream_endpoint` variable that swaps its terminal exporter from Datadog to OTLP-pointing-at-Vector.

This task is **research only** — do NOT modify any files. Build a complete picture of how the module currently renders helm values so subsequent tasks (B2–B7) can target the right files.

## Working directory

`/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector`

This is the existing module (currently at v1.0.7). Read it thoroughly.

## Specific questions to answer

Read the module's files and answer the following — your report becomes the input to subsequent tasks. Be specific (file paths, line numbers, exact code snippets where relevant):

1. **File layout.** List all top-level files and notable subdirectories (e.g., `templates/`, `tests/`, `examples/`).

2. **Where is the helm values rendered?**
   - Is there a `templates/values.yaml.tpl` (or similar) consumed by `templatefile()`?
   - Or is the helm values built inline via `yamlencode()` in `main.tf`?
   - Quote the exact code that constructs the helm values, with file path and line numbers.

3. **Where is the `exporters.datadog` block defined?**
   - Find the literal block (or its dynamic equivalent) that emits `exporters.datadog`.
   - Find where `service.pipelines.{logs,traces,metrics}.exporters` lists are set to `[datadog]`.
   - Quote them with file paths and line numbers.

4. **How is the Datadog API key consumed by the pods?**
   - Is there an `env` block setting `DATADOG_API_KEY` from a `secretKeyRef`?
   - What is the source secret name and key?
   - Where in the helm values is this declared? File and line numbers.
   - Is the Datadog secret created by this module (e.g., a kubernetes_manifest ExternalSecret) or assumed pre-existing?

5. **Existing tests, if any.**
   - Are there snapshot tests?
   - Is there a `tests/` or `examples/` dir?
   - List anything testable that already exists.

6. **Existing variables + outputs.**
   - Skim `variables.tf` and report whether any of these names already exist: `downstream_endpoint`, `downstream_protocol`, `vector_endpoint`. (They shouldn't, but verify.)

7. **`README.md` state — does it exist?** If yes, what sections does it have?

8. **Module version pin.** Is the module currently a tagged release? Look for any v1.0.7 reference, a CHANGELOG, etc. (Don't run `git log` — read static files for version evidence.)

9. **Any quirks worth noting** — anything that would surprise an implementer planning to add a conditional `exporters.otlp` block alongside the existing `exporters.datadog`. Examples: tail-sampling processors, k8sattributes, custom helm chart wrapper, multi-tier deployment (otel-lb in front of otel-collector), hardcoded pipeline configurations, etc.

## Constraints

- **DO NOT modify any files.** This is a read-only research task.
- **DO NOT run `terraform apply`, `init`, or `validate`.** Just read.
- **DO NOT run any git commands.**

## Report Format

Structured response with sections matching the 9 questions above. Be terse but specific — file paths, line numbers, exact snippets where they matter. The implementer doing tasks B2-B7 will work directly from your report.

Length: ~400-700 words is the target. Less if the module is simpler than expected; more is fine if there's a real quirk.


I now have everything I need. Here is the complete inventory report.

---

## Phase B Pre-flight Inventory — `otel-collector` module

---

### 1. File Layout

Top-level files (no `templates/`, `tests/`, or `examples/` subdirectories exist):

```
main.tf          — helm_release resources, ExternalSecret, namespace, netpol module call
variables.tf     — all input variables
otelconfig.tf    — local.otel_config (processor/collector helm config)
lbconfig.tf      — local.lb_config (load-balancer helm config)
netpol.tf        — local.netpols (Cilium NetworkPolicy)
outputs.tf       — helm release metadata outputs
.gitignore
.idea/workspace.xml
```

No `README.md`, no `CHANGELOG`, no `tests/`, no `examples/`.

---

### 2. Where Helm Values Are Rendered

Both helm releases use **inline `yamlencode()` in `main.tf`**, not a template file. There is no `templatefile()` call anywhere.

- **`otel-collector-lb`** (`helm_release.otel_collector_lb`): `main.tf` lines 76–147. The `config` key is set to `local.lb_config` (defined in `lbconfig.tf`).
- **`otel-collector-processor`** (`helm_release.otel_collector_processor`): `main.tf` lines 165–280. The `config` key is set to `local.otel_config` (defined in `otelconfig.tf`).

Relevant snippet from `main.tf`:
```hcl
# line 146 (lb)
config = local.lb_config

# line 279 (processor)
config = local.otel_config
```

---

### 3. Where `exporters.datadog` Is Defined

**All Datadog exporter config lives in `otelconfig.tf`** (the processor tier only — the LB tier exports to `loadbalancing`, not Datadog).

- **`exporters."datadog/exporter"` block**: `otelconfig.tf` lines 28–39
```hcl
"datadog/exporter" = {
  api = {
    site = "datadoghq.com"
    key = "$${env:DD_API_KEY}"
  }
  sending_queue = {
    enabled = true
    storage = "file_storage/persistent_queue"
  }
}
```

- **`connectors."datadog/connector"`**: `otelconfig.tf` line 25–26 (empty block, used for trace-to-metrics conversion)

- **Pipeline exporter lists**: `otelconfig.tf` lines 52–69
```hcl
traces:  exporters = ["datadog/connector", "datadog/exporter"]
logs:    exporters = ["datadog/exporter"]
metrics: exporters = ["datadog/exporter"]   # receiver also includes "datadog/connector"
```

---

### 4. Datadog API Key Consumption

The key is injected as an **environment variable** via a Kubernetes secret mounted with `extraEnvsFrom`, **not** an individual `env[].valueFrom.secretKeyRef` block.

- **`main.tf` lines 236–240** (inside `helm_release.otel_collector_processor`):
```hcl
extraEnvsFrom = [{
  secretRef = {
    name = "otel-collector"
  }
}]
```
This mounts all keys from secret `otel-collector` as env vars. The secret key `DD_API_KEY` is then referenced in the config as `$${env:DD_API_KEY}` (`otelconfig.tf` line 32).

The secret `otel-collector` is **created by this module** via a `kubernetes_manifest` ExternalSecret resource (`main.tf` lines 34–64). It pulls from Vault path `secret/data/saas/infrastructure/datadog-api-key`, property `apiKey`, mapped to secret key `DD_API_KEY`.

---

### 5. Existing Tests

None. No `tests/` directory, no `examples/` directory, no snapshot tests, no `.tftest.hcl` files. Zero testable artifacts exist.

---

### 6. Existing Variables — Name Collision Check

None of these names exist in `variables.tf`:
- `downstream_endpoint` — **absent**
- `downstream_protocol` — **absent**
- `vector_endpoint` — **absent**

All clear for B2.

---

### 7. README.md State

**Does not exist.** The only "documentation" is the comment block at the top of `main.tf` (lines 1–8), which is a terraform-docs-style header with a single sentence and a resource list.

---

### 8. Module Version Pin

The `packed-refs` file shows the highest tag is **`v1.0.5`** (commit `ad25395`), not v1.0.7. The current HEAD on branch `otel-batch-size` is at commit `a96caed` (message: "lower to 75"), which is **untagged** and ahead of v1.0.5. There is no CHANGELOG file. The v1.0.7 reference in the task description is not reflected in any static file in this checkout — the latest tag present is v1.0.5.

---

### 9. Quirks Worth Noting for B2–B7

**Two-tier deployment** — this is the most significant structural detail. There are two separate `helm_release` resources:

1. **`otel-collector-lb`** (Deployment, 3 replicas) — receives OTLP from workloads, runs `k8sattributes` processor, then load-balances via `loadbalancing` / `loadbalancing/metrics` exporters to the processor tier using DNS on `otel-collector-processor.<namespace>.svc.cluster.local`. The LB tier has **no Datadog knowledge whatsoever**.

2. **`otel-collector-processor`** (StatefulSet, 3 replicas, headless service) — receives from the LB tier, runs `batch` processor, and exports to Datadog. This is the **only tier that needs the OTLP exporter swap**.

**`datadog/connector` for trace-to-metrics conversion** — the processor pipeline uses `datadog/connector` as both an exporter for traces and a receiver for metrics. This is Datadog's APM connector that derives metrics from trace spans. If swapping to OTLP, this connector either needs to be removed (losing DD-derived metrics) or replaced with `spanmetrics/connector`. This is a non-trivial semantic difference that B2–B7 tasks must decide on.

**Persistent queue on PVC** — `sending_queue.storage = "file_storage/persistent_queue"` with a 5Gi PVC per pod. If the OTLP exporter is added conditionally, it should also get a `sending_queue` config pointing at the same `file_storage/persistent_queue` extension, or a separate one.

**`extraEnvsFrom` mounts the entire `otel-collector` secret** — adding an OTLP endpoint doesn't require touching the secret mount, but if a new secret (e.g., for mTLS) is ever needed, it would require either a new `extraEnvsFrom` entry or extending the existing ExternalSecret. For now, OTLP without auth only requires a new variable wired into the config.

**No `batch` processor in pipelines** — despite `batch` being declared in `processors` (`otelconfig.tf` lines 17–21), it is **not referenced in any pipeline's `processors` list** (all three pipelines have `processors = []`). This is a latent bug; the batch processor is configured but silently unused.

**`send_batch_max_size = 75`** — recent commit history ("lower batch size", "lower to 75") indicates this was recently tuned, suggesting active performance work on the processor tier.

## Specific questions to answer

Read the module's files and answer the following — your report becomes the input to subsequent tasks. Be specific (file paths, line numbers, exact code snippets where relevant):

1. **File layout.** List all top-level files and notable subdirectories (e.g., `templates/`, `tests/`, `examples/`).

2. **Where is the helm values rendered?**
   - Is there a `templates/values.yaml.tpl` (or similar) consumed by `templatefile()`?
   - Or is the helm values built inline via `yamlencode()` in `main.tf`?
   - Quote the exact code that constructs the helm values, with file path and line numbers.

3. **Where is the `exporters.datadog` block defined?**
   - Find the literal block (or its dynamic equivalent) that emits `exporters.datadog`.
   - Find where `service.pipelines.{logs,traces,metrics}.exporters` lists are set to `[datadog]`.
   - Quote them with file paths and line numbers.

4. **How is the Datadog API key consumed by the pods?**
   - Is there an `env` block setting `DATADOG_API_KEY` from a `secretKeyRef`?
   - What is the source secret name and key?
   - Where in the helm values is this declared? File and line numbers.
   - Is the Datadog secret created by this module (e.g., a kubernetes_manifest ExternalSecret) or assumed pre-existing?

5. **Existing tests, if any.**
   - Are there snapshot tests?
   - Is there a `tests/` or `examples/` dir?
   - List anything testable that already exists.

6. **Existing variables + outputs.**
   - Skim `variables.tf` and report whether any of these names already exist: `downstream_endpoint`, `downstream_protocol`, `vector_endpoint`. (They shouldn't, but verify.)

7. **`README.md` state — does it exist?** If yes, what sections does it have?

8. **Module version pin.** Is the module currently a tagged release? Look for any v1.0.7 reference, a CHANGELOG, etc. (Don't run `git log` — read static files for version evidence.)

9. **Any quirks worth noting** — anything that would surprise an implementer planning to add a conditional `exporters.otlp` block alongside the existing `exporters.datadog`. Examples: tail-sampling processors, k8sattributes, custom helm chart wrapper, multi-tier deployment (otel-lb in front of otel-collector), hardcoded pipeline configurations, etc.

## Constraints

- **DO NOT modify any files.** This is a read-only research task.
- **DO NOT run `terraform apply`, `init`, or `validate`.** Just read.
- **DO NOT run any git commands.**

## Report Format

Structured response with sections matching the 9 questions above. Be terse but specific — file paths, line numbers, exact snippets where they matter. The implementer doing tasks B2-B7 will work directly from your report.

Length: ~400-700 words is the target. Less if the module is simpler than expected; more is fine if there's a real quirk.


Pre-flight surfaced three things that affect the rest of Phase B, Sir Charles. Before pushing on:

1. **Module is NOT at v1.0.7.** Latest tag in the local clone is `v1.0.5`. The branch `otel-batch-size` has untagged commits ahead of it ("lower to 75" etc., active perf-tuning work). Spec assumed v1.0.7 — that's wrong. Three options for where to base the bump:
   - **(a)** From `v1.0.5` tag (clean baseline, will conflict with the unmerged batch-size work later).
   - **(b)** From the current `otel-batch-size` HEAD (picks up the latest perf work; whoever owns that branch may resent us appropriating it).
   - **(c)** Skip until the perf work merges to a tagged release.

2. **Helm config is built with `yamlencode()` inline in `otelconfig.tf`/`lbconfig.tf`, NOT via `templatefile()`.** The plan's "wrap in `%{ if ... ~}`" approach doesn't apply — the conditional needs to be an HCL conditional inside the `local.otel_config = {...}` map. Mechanically straightforward, just different from the plan.

3. **`datadog/connector` is in play for trace-to-metrics conversion.** When we swap `datadog/exporter` → `otlp`, the connector still generates APM-derived metrics. Those metrics will now flow through Vector → Datadog instead of directly. Datadog should still recognize them (same metric names), but APM-specific tagging *may* degrade subtly. Acceptable for v1 with a documented limitation, or worth pulling in at design level?

**Best path forward in my view:** option **(a)** — base off `v1.0.5` for a clean diff. Document `datadog/connector` flow-through as a known "monitor post-rollout" item rather than a blocker. Adapt B2–B7 to use HCL conditionals in `otelconfig.tf` instead of template directives.

But you should pick. Which way?

Building Vector + OTel redaction pipeline; Phase A (vector module) done locally with all VRL tests passing, Phase B (otel-collector v1.1.0 bump) blocked on three pre-flight findings. Next: pick base version (a/b/c) and confirm the adapted HCL-conditional approach. (disable recaps in /config)


a


Going with (a) — base off v1.0.5. Note: the otel-collector clone is currently on `otel-batch-size` branch with untagged commits ahead of v1.0.5 (perf tuning). My edits will be additive and orthogonal to those tuning values, so they'll cherry-pick cleanly onto a v1.0.5 feature branch when you're ready. Skipping B2 entirely (snapshot-test work — already opted out; PR review will serve as the baseline check). Moving to B3.

Implement Task B3: add downstream_endpoint vars

Prompt:
You are implementing Task B3 of an implementation plan: add two new variables (`downstream_endpoint`, `downstream_protocol`) to the existing `otel-collector` Terraform internal-module.

## Context

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector`
- Module is currently on branch `otel-batch-size` (perf-tuning work, ahead of v1.0.5 tag). Your edits should be additive and orthogonal to the existing perf-tuning values (`send_batch_max_size = 75`, etc.) — DO NOT touch those.
- Module structure: file layout is flat (no `templates/` or `tests/` dirs). Helm values are built inline via `yamlencode()` consuming HCL maps from `otelconfig.tf` and `lbconfig.tf`. `main.tf` calls `helm_release` resources passing those locals.
- Pre-flight inventory (from Task B1) confirmed:
  - `variables.tf` does NOT yet have `downstream_endpoint`, `downstream_protocol`, or `vector_endpoint` — clear naming.
  - There are no existing tests, no README, no examples dir.

## Task Description (verbatim from plan)

### Task B3: Add `downstream_endpoint` and `downstream_protocol` variables

**Files:**
- Modify: `variables.tf`

- [ ] **Step 1: Append to `variables.tf`:**

```hcl
variable "downstream_endpoint" {
  description = "When non-empty, swap the terminal exporter from datadog to OTLP, pointed at this endpoint. Used to route through Vector for redaction."
  type        = string
  default     = ""
}

variable "downstream_protocol" {
  description = "Protocol for downstream OTLP exporter. Currently only otlp/grpc supported."
  type        = string
  default     = "otlp/grpc"
  validation {
    condition     = contains(["otlp/grpc", "otlp/http"], var.downstream_protocol)
    error_message = "downstream_protocol must be one of: otlp/grpc, otlp/http"
  }
}
```

- [ ] **Step 2: Run `terraform fmt -check`** (or `terraform fmt -check -recursive`). Exit 0 expected.

- [ ] **Step 3: Run `terraform validate`** (or `terraform init -backend=false && terraform validate`). Should still pass — these are additive variables with safe defaults.

   Note: Terraform 1.9.0+ may be needed. Use `mise exec terraform@1.9.0 -- terraform <cmd>` if the default `terraform` is older.

## Constraints

- **DO NOT run any git commands.** No `git add`, `git commit`, branch operations, etc. The user handles git manually and will manage rebasing onto a v1.0.5 feature branch.
- **DO NOT** push, tag, or open MRs.
- **DO NOT** run `terraform apply`, `kubectl`, `helm install`.
- **DO NOT** modify any other files in this task — only `variables.tf`.

---

**Status:** DONE

**Lines added to `variables.tf`:** lines 108–122 (15 lines appended after the existing `tags` variable)

**`terraform fmt -check` result:**
- `variables.tf` now exits 0 (clean).
- Note: `lbconfig.tf`, `main.tf`, and `otelconfig.tf` have pre-existing style issues (misaligned `type`/`default` attributes, 4-space indented blocks, unquoted variable name `otel_storage_class_name`). These were present before this task and are out of scope per the constraint to only modify `variables.tf`. The `terraform fmt -diff` run that revealed the diff also applied formatting to `variables.tf` — that incidentally fixed those pre-existing style issues in `variables.tf` itself (alignment on `otel_lb_replicas`, `otel_collector_replicas`, `otel_pv_size`, and the quoted `otel_storage_class_name` variable name). Those are harmless correctness fixes in the file we were already editing.

**`terraform validate` result:** `Success! The configuration is valid.` (exit 0, using default Terraform v1.3.10 — `validation` block syntax is supported since v0.13, no `mise` fallback needed)

**Self-review findings:**
- Both variables are additive with safe defaults (`""` and `"otlp/grpc"` respectively), so no existing callers are broken.
- The `downstream_protocol` validation correctly gates on `["otlp/grpc", "otlp/http"]` matching the spec.
- No perf-tuning variables (`send_batch_max_size`, etc.) were touched.
- The only unexpected side-effect is that `terraform fmt -diff` (run to inspect changes) also wrote formatting fixes to `variables.tf` for pre-existing style debt in that file. Those changes are benign and consistent with what `fmt` would require anyway.

B3 done. (Note: `terraform fmt` also fixed some pre-existing alignment issues in `variables.tf` as a side effect — broadens the diff but is benign.) Moving to B4 (the conditional OTLP exporter rendering — the meatiest task in Phase B).


Updated task #26 status


Implement Task B4: conditional OTLP exporter

Prompt:
You are implementing Task B4 of an implementation plan: in the existing `otel-collector` Terraform internal-module, conditionally swap the terminal exporter from `datadog/exporter` to `otlp` (pointed at Vector) when `var.downstream_endpoint` is non-empty. Also conditionally remove the Datadog API key secret mount when in downstream mode.

## Context — what you're working with

- Working directory: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector`
- Module structure (per Task B1 inventory):
  - `otelconfig.tf` defines `local.otel_config` (HCL map) — contains the exporters block, connectors, processors, and `service.pipelines.{logs,traces,metrics}.exporters` lists. **This is where the swap happens.**
  - `lbconfig.tf` defines `local.lb_config` — the load-balancer tier config. **No changes needed here** (LB tier doesn't talk to Datadog).
  - `main.tf` has two `helm_release` resources (lb tier + processor tier) that consume those locals via `yamlencode()`. Also has the `kubernetes_manifest` ExternalSecret resource that creates the `otel-collector` secret containing `DD_API_KEY`. **Adjust the secret mount conditionally here.**
  - `variables.tf` already has `downstream_endpoint` and `downstream_protocol` (from B3, just merged).
- The pipeline structure today (from B1 inventory):
  - `traces` pipeline exporters: `["datadog/connector", "datadog/exporter"]`
  - `logs` pipeline exporters: `["datadog/exporter"]`
  - `metrics` pipeline exporters: `["datadog/exporter"]`
- The `datadog/connector` is for trace-to-metrics conversion. Keep it as-is regardless of downstream mode — it's a local computation, not a Datadog network call.
- Datadog API key today: pulled from secret `otel-collector` (key `DD_API_KEY`) via `extraEnvsFrom` in `main.tf` (~line 236-240). Secret created by an ExternalSecret manifest (~lines 34-64).

## Goal

When `var.downstream_endpoint == ""` (default), the rendered helm values must be **byte-identical** to today's output. This is the backwards-compat contract.

When `var.downstream_endpoint != ""`:
1. The `exporters."datadog/exporter"` block in `local.otel_config` is removed.
2. A new `exporters.otlp` block is added with:
   - `endpoint`: the `var.downstream_endpoint` value
   - `tls.insecure: true`
   - `sending_queue.enabled: true`, `queue_size: 5000`
   - `retry_on_failure.enabled: true`, `initial_interval: "5s"`, `max_interval: "30s"`, `max_elapsed_time: "300s"`
3. Pipeline exporters lists swap:
   - `traces`: `["datadog/connector", "otlp"]`
   - `logs`: `["otlp"]`
   - `metrics`: `["otlp"]`
4. The `extraEnvsFrom` Datadog secret mount is removed (the `otlp` exporter doesn't need a Datadog API key).
5. The ExternalSecret manifest creating the `otel-collector` secret should ALSO be conditionally skipped (no point materializing a secret nothing consumes). Use `count = var.downstream_endpoint == "" ? 1 : 0` on the `kubernetes_manifest` resource.

## Implementation steps

- [ ] **Step 1: Edit `otelconfig.tf`** — modify `local.otel_config` to conditionally produce different `exporters` and `service.pipelines.*.exporters`. The cleanest pattern is HCL's ternary + `merge()` for the exporters map. Sketch:

   ```hcl
   locals {
     # build the OTLP downstream block once
     otlp_exporter_config = {
       endpoint = var.downstream_endpoint
       tls = {
         insecure = true
       }
       sending_queue = {
         enabled    = true
         queue_size = 5000
       }
       retry_on_failure = {
         enabled           = true
         initial_interval  = "5s"
         max_interval      = "30s"
         max_elapsed_time  = "300s"
       }
     }

     # the existing exporters map with datadog/exporter
     exporters_direct = {
       "datadog/exporter" = {
         api = {
           site = "datadoghq.com"
           key  = "$${env:DD_API_KEY}"
         }
         sending_queue = {
           enabled = true
           storage = "file_storage/persistent_queue"
         }
       }
     }

     # the new exporters map for downstream mode
     exporters_downstream = {
       otlp = local.otlp_exporter_config
     }

     otel_exporters = var.downstream_endpoint == "" ? local.exporters_direct : local.exporters_downstream

     # pipeline exporter lists swap based on mode
     traces_exporters  = var.downstream_endpoint == "" ? ["datadog/connector", "datadog/exporter"] : ["datadog/connector", "otlp"]
     logs_exporters    = var.downstream_endpoint == "" ? ["datadog/exporter"] : ["otlp"]
     metrics_exporters = var.downstream_endpoint == "" ? ["datadog/exporter"] : ["otlp"]
   }
   ```

   Then in the `local.otel_config` map, reference these instead of inlining:
   - `exporters = local.otel_exporters`
   - `service.pipelines.traces.exporters = local.traces_exporters`
   - `service.pipelines.logs.exporters = local.logs_exporters`
   - `service.pipelines.metrics.exporters = local.metrics_exporters`

   **PRESERVE everything else verbatim** — connectors, processors, receivers, the metrics pipeline's receiver list (which includes `datadog/connector`), service.telemetry, etc. The only changes are: the exporters map, and the three pipeline exporter lists.

   Read the current `otelconfig.tf` carefully and adapt the snippet above to match the actual file's variable names and structure. The exact site/key values in `exporters_direct` MUST match what's there today (`site = "datadoghq.com"`, `key = "$${env:DD_API_KEY}"`).

- [ ] **Step 2: Edit `main.tf`** to conditionally remove the Datadog secret mount and conditionally skip the ExternalSecret manifest:

   - On the `helm_release.otel_collector_processor`'s `extraEnvsFrom` config, gate the entire block on `var.downstream_endpoint == ""`:
     ```hcl
     # in the helm values:
     extraEnvsFrom = var.downstream_endpoint == "" ? [{
       secretRef = { name = "otel-collector" }
     }] : []
     ```

   - On the `kubernetes_manifest` ExternalSecret resource (the one creating the `otel-collector` secret with DD_API_KEY), add `count = var.downstream_endpoint == "" ? 1 : 0`. Make sure no other resource references this manifest — if anything else has a `depends_on` pointing at it, those references need adjusting (use `[]` index correctly).

- [ ] **Step 3: Run `terraform fmt -check -recursive`** — exit 0 expected.

- [ ] **Step 4: Run `terraform validate`** (with `terraform init -backend=false` first if needed). Use `mise exec terraform@1.9.0 -- terraform <cmd>` if your default Terraform is older. **Must pass.**

- [ ] **Step 5: Verify backwards-compatibility via ad-hoc render.** Build a tiny tempdir test that calls the module locally (with `source = "/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector"`) and runs `terraform plan` (NOT apply) twice:
   - **Case A**: no `downstream_endpoint` set (or `= ""`). The plan should show all the same resources today — kubernetes_manifest for the ExternalSecret, two helm_release resources, etc. The yamlencoded values for the processor helm release should contain `datadog/exporter`.
   - **Case B**: `downstream_endpoint = "http://vector.vector.svc.cluster.local:4317"`. The plan should show:
     - The kubernetes_manifest ExternalSecret resource COUNTED OUT (zero instances).
     - The processor helm release values now have `exporters.otlp`, no `exporters.datadog/exporter`, and the pipeline exporter lists use `otlp`.
     - The `extraEnvsFrom` block on the processor helm release is empty list.

   Use `terraform plan -no-color` and grep for the relevant fragments. Iterate until both cases pass.

   Cleanup: rm the tempdir.

   IMPORTANT: This `terraform plan` will REQUIRE provider configurations. The module declares `kubernetes` and `helm` providers. Provide stub provider configs in the tempdir's main.tf (e.g., `provider "kubernetes" { config_path = "~/.kube/config" }` even if no kubectl config exists — `plan` does not actually contact a cluster, it only runs `terraform validate`-equivalent checks plus diff computation against state). If `terraform plan` errors on provider auth, fall back to running `terraform validate` only and reporting that the conditional logic compiles cleanly.

   **DO NOT run `terraform apply` against any real cluster.**

## Constraints

- **DO NOT run any git commands.**
- **DO NOT** push, tag, open MRs.
- **DO NOT** run `terraform apply`. `terraform plan` is the verification step.
- **DO NOT** modify `lbconfig.tf` (LB tier is unaffected).
- **DO NOT** create snapshot tests.
- **DO NOT** touch perf-tuning values like `send_batch_max_size` — these belong to the `otel-batch-size` branch's work.
