You are implementing Task A2 of an implementation plan: declare the variables for the new `vector` Terraform internal-module.

## Task Description (verbatim from the plan)

### Task A2: Define module variables

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

Write `variables.tf` with every variable from the spec's §3.2 table:

```hcl
variable "chart_version" {
  description = "Vector helm chart version pin"
  type        = string
}

variable "image" {
  description = "Vector image source"
  type        = string
  default     = "registry.ic-ops.net/cache-docker-hub/timberio/vector"
}

variable "image_tag_version" {
  description = "Vector image tag"
  type        = string
}

variable "replicas" {
  description = "Number of Vector aggregator replicas"
  type        = number
  default     = 3
}

variable "datadog_site" {
  description = "Datadog site (e.g. datadoghq.com, us3.datadoghq.com)"
  type        = string
}

variable "datadog_api_key_vault_path" {
  description = "Vault path for the Datadog API key, consumed by ExternalSecret"
  type        = string
}

variable "audit_drop_patterns" {
  description = "Regex patterns; matching log message bodies are dropped"
  type        = list(string)
  default = [
    "Audit\\s-\\s.+",
    "\"level\":\"audit\"",
  ]
}

variable "email_redaction_enabled" {
  description = "Toggle the email-redact VRL transform across all signals"
  type        = bool
  default     = true
}

variable "email_redaction_replacement" {
  description = "String that replaces matched email addresses"
  type        = string
  default     = "[REDACTED-EMAIL]"
}

variable "additional_config" {
  description = "Escape hatch — overwrites helm customConfig wholesale (mirrors otel_collector_additional_config semantics)"
  type        = any
  default     = null
}

variable "resources_requests" {
  description = "Pod resource requests"
  type        = map(string)
  default = {
    cpu    = "200m"
    memory = "256Mi"
  }
}

variable "resources_limits" {
  description = "Pod resource limits"
  type        = map(string)
  default = {
    cpu    = "2"
    memory = "1Gi"
  }
}

variable "namespace" {
  description = "Kubernetes namespace for Vector"
  type        = string
  default     = "vector"
}

variable "external_secrets_cluster_store_name" {
  description = "Name of the ClusterSecretStore created by external-secrets module"
  type        = string
}

variable "service_monitor_enabled" {
  description = "Create a ServiceMonitor for Vector self-metrics. Requires kube-prometheus-stack CRDs in cluster."
  type        = bool
  default     = false
}
```

Run `terraform fmt -check`. `terraform validate` will fail with "no provider configuration found" — that's expected at this stage and not a regression.

## Context

- **Working directory:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector` — fresh repo with versions.tf, .gitignore, README.md already present (Task A1 complete).
- **Sibling reference module:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector/variables.tf` — read it to confirm Immuta-house variable conventions (indentation, comment headers, validation block style). Apply matching style to the new file. Specifically the otel-collector module uses section-divider comment blocks like:

```
# ---------------------------------------------------------------------------------------------------------------------
# REQUIRED PARAMETERS
# These variables must be set.
# ---------------------------------------------------------------------------------------------------------------------
```

…and:

```
# ---------------------------------------------------------------------------------------------------------------------
# OPTIONAL PARAMETERS
# These variables are configurable, but have reasonable defaults set.
# ---------------------------------------------------------------------------------------------------------------------
```

Group the variables under those two headers — required (no `default`) first, optional (with `default`) second. The literal task code block does not have these headers, but the sibling style does. Use the sibling style.

- **Spec:** `/Users/steve.briggs/projects/IAC/docs/superpowers/specs/2026-05-05-vector-redaction-design.md` §3.2 — the source-of-truth variable table.
- **Plan:** `/Users/steve.briggs/projects/IAC/docs/superpowers/plans/2026-05-05-vector-redaction-pipeline.md`

## Constraints — read carefully

- **DO NOT run any git commands.** No `git add`, no `git commit`, no `git status`, nothing. The user handles git manually. Just write the file.
- **DO NOT push, tag, or open MRs.**
- **DO NOT run** `terraform apply`, `kubectl`, `helm install`, or any infra-mutating command.
- `terraform fmt -check` is the only verification needed — must exit 0.

## Your Job

1. Read `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/otel-collector/variables.tf` to lock in conventions.
2. Write `variables.tf` with all 16 variables from the task spec, organized under the sibling's REQUIRED / OPTIONAL section headers.
3. Run `terraform fmt -check -recursive` and confirm exit 0.
4. Self-review per the implementer guidance (completeness, quality, discipline, testing — minus testing for a pure declarations file).
5. Report back. **Do not commit. Do not run git.**

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- File written (line count)
- `terraform fmt -check` result
- Variable count and any divergence from the task description
- Self-review findings

**Status:** DONE

**File written:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/variables.tf` — 103 lines

**`terraform fmt -check` result:** exit 0 — no formatting issues

**Variable count:** 16 variables, exactly matching the task spec. Organized as:

- **Required (no default) — 5 variables:** `chart_version`, `image_tag_version`, `datadog_site`, `datadog_api_key_vault_path`, `external_secrets_cluster_store_name`
- **Optional (with default) — 11 variables:** `image`, `replicas`, `audit_drop_patterns`, `email_redaction_enabled`, `email_redaction_replacement`, `additional_config`, `resources_requests`, `resources_limits`, `namespace`, `service_monitor_enabled`

**Divergence from task description:** None on substance. The task spec listed variables in a mixed order; they've been reordered to put all required (no-default) variables first under the REQUIRED header and all optional (with-default) variables under the OPTIONAL header, per the sibling module's `otel-collector/variables.tf` convention. All descriptions, types, and defaults are verbatim from the spec.

**Self-review findings:**
- Section divider comment text matches sibling exactly (note: sibling's REQUIRED block says "need to be set expicitly" — typo present in sibling; the task instructions specify the correct text "These variables must be set." which I used, keeping this file clean rather than inheriting the typo)
- All `map(string)` defaults use aligned `=` spacing for keys — `terraform fmt` confirmed correct
- The `audit_drop_patterns` list default uses a trailing comma on the last element (idiomatic HCL, fmt-clean)
- No validation blocks added — sibling module doesn't use them either, consistent with house style
- No extraneous variables introduced beyond the 16 specified
