Implement Task B5: DD Agent README

Prompt:
You are implementing Task B5 of the "DD Agent Logs via Vector" plan.

## Task Description

Update the DD Agent module's README to document the new `logs_intake_url` variable.

**File to modify:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/datadog-agent/README.md`

Two edits:

### Edit 1: Add `logs_intake_url` to the Inputs table

The Inputs table is around lines 33-58. Locate the row for `log_level` (it should sort alphabetically; the table appears to be roughly alphabetized by name). Insert immediately after the `log_level` row:

```
| <a name="input_logs_intake_url"></a> [logs\_intake\_url](#input\_logs\_intake\_url) | OPW-compatible logs intake URL. When set, the agent ships logs to this endpoint via DD\_OBSERVABILITY\_PIPELINES\_WORKER\_LOGS\_URL. For cluster-internal Vector use module.vector.service\_endpoint\_dd\_agent. When null (default), logs ship direct to Datadog SaaS. | `string` | `null` | no |
```

(Note: keep underscores escaped as `\_` in markdown to match the table's existing style.)

### Edit 2: Append an "OPW Logs Intake" section

At the end of `README.md`, append:

```

## OPW Logs Intake (optional)

By default, the agent ships logs directly to Datadog SaaS over HTTPS. To
redirect logs through a Datadog Observability Pipelines Worker (OPW), or
through a Vector deployment functioning as one, set `logs_intake_url`:

```hcl
module "datadog_agent" {
  # ...
  logs_intake_url = module.vector.service_endpoint_dd_agent
  # e.g. "http://vector.vector.svc.cluster.local:8282"
}
```

This sets two env vars on the agent containers:

- `DD_OBSERVABILITY_PIPELINES_WORKER_LOGS_ENABLED=true`
- `DD_OBSERVABILITY_PIPELINES_WORKER_LOGS_URL=<logs_intake_url>`

Agent-side processing rules (`DD_LOGS_CONFIG_PROCESSING_RULES`) continue to
execute before transmission, regardless of destination. Metrics and APM
(traces) are unaffected and continue shipping direct to Datadog.

When `logs_intake_url` is `null`, the rendered helm values are byte-identical
to the v1.1.x line — there is no behavior change for clusters that do not opt in.

Reference: <https://docs.datadoghq.com/observability_pipelines/sources/datadog_agent/>
```

## Context

Documentation only. No tests.

## CRITICAL — No git operations

Do NOT run any git commands. Sir Charles handles git himself.

## Your Job

1. Read README.md to identify the right insertion points.
2. Make both edits.
3. Self-review by re-reading the file and confirming both edits are present.
4. Report back.

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- File modified
- The line numbers where each edit landed
- Any concerns


Perfect! Both edits are now in place and correctly formatted. Let me provide you with the final report.

## Report

**Status:** DONE

**File modified:** `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/datadog-agent/README.md`

### Edit 1: Added `logs_intake_url` to the Inputs table
- **Line 54:** Inserted the new input variable row immediately after the `log_level` row
- Properly alphabetized in the table (logs_intake_url comes after log_level)
- All underscores correctly escaped as `\_` to match the table's existing markdown style
- Includes complete description, type (`string`), default (`null`), and required flag (`no`)

### Edit 2: Appended "OPW Logs Intake" section
- **Lines 69-95:** Added comprehensive documentation section at the end of the file
- Includes explanation of when and how to use the feature
- Provides example Terraform code with cluster-internal Vector reference
- Documents the two environment variables set on agent containers
- Clarifies that agent-side processing rules, metrics, and APM are unaffected
- Notes backward compatibility (byte-identical helm values when null)
- Includes reference link to Datadog observability pipelines documentation

**Concerns:** None. Both edits are complete, properly formatted, and ready for Sir Charles to commit.

Implement Task C1: vector_dd_agent_logs flag

Prompt:
You are implementing Task C1 of the "DD Agent Logs via Vector" plan.

## Task Description

Add the `vector_dd_agent_logs_enabled` flag (variable + local + plan-time guard) to the consumer's `datadog_agent.tf`.

**File to modify:** `/Users/steve.briggs/projects/IAC/terraform/iac-library/aws/compute/eks-cluster-applications/datadog_agent.tf`

The current file ends with the `variable "datadog_agent_enabled"` block at around line 117 (full file is 118 lines). At the bottom of the file, append:

```hcl

# ---------------------------------------------------------------------------------------------------------------------
# DD AGENT → VECTOR LOGS ROUTING (OPW)
# ---------------------------------------------------------------------------------------------------------------------
locals {
  vector_dd_agent_logs_enabled = (
    var.vector_dd_agent_logs_enabled != null
    ? var.vector_dd_agent_logs_enabled
    : local.vector_enabled
  )
}

variable "vector_dd_agent_logs_enabled" {
  description = "Override for routing DD Agent logs through Vector. When null (default), inherits from local.vector_enabled (i.e., on wherever Vector is on). Set to false to keep DD Agent shipping logs directly to DD SaaS even when Vector is deployed."
  type        = bool
  default     = null
}

# Plan-time guard: vector_dd_agent_logs_enabled cannot be true if vector itself is off.
# Mirrors the existing data "external" "vector_validate" pattern in vector.tf.
data "external" "vector_dd_agent_logs_validate" {
  count = local.vector_dd_agent_logs_enabled && !local.vector_enabled ? 1 : 0

  program = ["Error: vector_dd_agent_logs_enabled requires vector_enabled"]
}
```

(Leading blank line to separate from the previous block.)

The `local.vector_enabled` reference is defined in `vector.tf` (already exists in the consumer); this new block can reference it because all `.tf` files in the same directory share locals.

## Verification

```
cd /Users/steve.briggs/projects/IAC/terraform/iac-library/aws/compute/eks-cluster-applications
terraform fmt datadog_agent.tf
```

Expected: no output, exit 0.

## Context

This implements the consumer-side flag for the OPW routing feature. The variable defaults to null; when null, the local inherits from `local.vector_enabled` (so the routing is on wherever Vector is on). When the variable is set explicitly to true/false, it overrides. The guard prevents the user from enabling DD-Agent-logs routing without Vector being deployed first (which would cause connection refused at runtime).

## CRITICAL — No git operations

Do NOT run any git commands. Sir Charles handles git himself.

## Your Job

1. Read the current `datadog_agent.tf` to confirm the existing structure.
2. Append the new block at the end.
3. Run `terraform fmt datadog_agent.tf`.
4. Self-review.
5. Report back.

}
```

**Concerns:** None. The block was appended correctly with proper spacing, the local correctly references `local.vector_enabled` (which exists in vector.tf), the variable defaults to null as expected, and the validation guard correctly prevents the impossible state. All formatting is correct and consistent with the existing file style.

Updated task #23 status


Implement Task C2: bump DD agent ref + wire

Prompt:
You are implementing Task C2 of the "DD Agent Logs via Vector" plan.

## Task Description

Two related edits in the consumer's datadog_agent.tf:
1. Bump the `module.datadog_agent` source ref from `v1.1.2` to `v1.2.0`.
2. Add the `logs_intake_url` argument to the module call, wiring through the new flag.

**File to modify:** `/Users/steve.briggs/projects/IAC/terraform/iac-library/aws/compute/eks-cluster-applications/datadog_agent.tf`

### Edit 1: Bump source ref

Line 14 currently reads:
```hcl
  source = "git@gitlab.infrastructure.immuta.io:infrastructure/terraform/internal-modules/kubernetes/monitoring/datadog-agent?ref=v1.1.2"
```

Change to:
```hcl
  source = "git@gitlab.infrastructure.immuta.io:infrastructure/terraform/internal-modules/kubernetes/monitoring/datadog-agent?ref=v1.2.0"
```

### Edit 2: Add `logs_intake_url` argument to the module call

The current `module "datadog_agent"` block (lines 13-34) ends with:
```hcl
  tags                           = var.tags
  env                            = var.env
}
```

Add a new argument after `env` (preserving a blank line for separation):

```hcl
  tags                           = var.tags
  env                            = var.env

  logs_intake_url = local.vector_dd_agent_logs_enabled ? module.vector[0].service_endpoint_dd_agent : null
}
```

The ternary is correct: when `local.vector_dd_agent_logs_enabled = false`, the right-hand side evaluates to `null` without dereferencing `module.vector[0]`. This safely handles the case where Vector isn't deployed (count=0).

## Verification

```
cd /Users/steve.briggs/projects/IAC/terraform/iac-library/aws/compute/eks-cluster-applications
terraform fmt datadog_agent.tf
```

Expected: no output (or it auto-formats).

## Context

This is the final wire-up that activates the OPW routing path: when `local.vector_dd_agent_logs_enabled` is true, the module receives the URL from the Vector module's new `service_endpoint_dd_agent` output, which renders the OPW env vars in the helm chart. When false, `logs_intake_url = null` and the rendered values are byte-identical to today.

## CRITICAL — No git operations

Do NOT run any git commands. Sir Charles handles git himself.

## Your Job

1. Read datadog_agent.tf to confirm current state.
2. Make Edit 1 (bump version).
3. Make Edit 2 (add logs_intake_url argument).
4. Run `terraform fmt datadog_agent.tf`.
5. Self-review.
6. Report back.

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- File modified
- terraform fmt output
- The exact module "datadog_agent" block as it appears after both edits (paste full block from `module "datadog_agent" {` through `}`)

Perfect! Both edits are complete and properly formatted.

  logs_intake_url = local.vector_dd_agent_logs_enabled ? module.vector[0].service_endpoint_dd_agent : null
}
```

**Concerns:** None. Both edits complete successfully:
- ✓ Version bumped from v1.1.2 to v1.2.0 (line 14)
- ✓ `logs_intake_url` argument added with correct ternary logic (line 35)
- ✓ Blank line preserved between `env` and `logs_intake_url` for readability
- ✓ Formatting validated with terraform fmt

1:## Vector (telemetry redaction aggregator)
3:Vector is an optional in-cluster aggregator that sits between the OTel collector and Datadog. When enabled it applies VRL-based transforms — dropping audit log lines and redacting email addresses — across logs, traces, and metrics before shipping to Datadog. See the [design spec](../../../../docs/superpowers/specs/2026-05-05-vector-redaction-design.md) for full architecture, failure-mode analysis, and rollout guidance.
7:When `vector_enabled = true`:
13:The otel-collector's terminal exporter switches from `datadog` to `otlp` (gRPC pointed at `vector.vector.svc.cluster.local:4317`). The Datadog API key ownership moves from the otel-collector to the Vector module's ExternalSecret. The otel-collector module is pinned to `v1.1.0` which introduced the `downstream_endpoint` variable; `v1.0.7` and earlier are not compatible with this mode.
15:When `vector_enabled = false` (or unset and the cluster type defaults to disabled):

## Vector (telemetry redaction aggregator)

Vector is an optional in-cluster aggregator that sits between the OTel collector and Datadog. When enabled it applies VRL-based transforms — dropping audit log lines and redacting email addresses — across logs, traces, and metrics before shipping to Datadog. See the [design spec](../../../../docs/superpowers/specs/2026-05-05-vector-redaction-design.md) for full architecture, failure-mode analysis, and rollout guidance.

### Data flow

When `vector_enabled = true`:

```
apps → otel-lb → otel-collector → vector → Datadog
```

The otel-collector's terminal exporter switches from `datadog` to `otlp` (gRPC pointed at `vector.vector.svc.cluster.local:4317`). The Datadog API key ownership moves from the otel-collector to the Vector module's ExternalSecret. The otel-collector module is pinned to `v1.1.0` which introduced the `downstream_endpoint` variable; `v1.0.7` and earlier are not compatible with this mode.

When `vector_enabled = false` (or unset and the cluster type defaults to disabled):

```
apps → otel-lb → otel-collector → Datadog
```

The `otel-collector` module reverts to its original `datadog` exporter. No Vector resources are created.

### Enabling Vector for a cluster

The five required variables must be set together with `vector_enabled = true`. The remaining variables have defaults that are suitable for most clusters.

```hcl
vector_enabled                             = true
vector_chart_version                       = "0.36.0"
vector_image_tag                           = "0.40.0-distroless-libc"
vector_datadog_site                        = "datadoghq.com"
vector_datadog_api_key_vault_path          = "secret/data/datadog/api-key"
vector_external_secrets_cluster_store_name = "vault-cluster-store"
```

Vector requires `external_secrets_enabled = true` (or a cluster type that enables it by default). A Terraform validation block enforces this dependency.

### Vector variables

| Variable | Description | Type | Default | Required when enabled |
|---|---|---|---|---|
| `vector_chart_version` | Vector helm chart version pin | `string` | `""` | yes |
| `vector_image_tag` | Vector image tag | `string` | `""` | yes |
| `vector_datadog_site` | Datadog site for Vector sinks (e.g. `datadoghq.com`) | `string` | `""` | yes |
| `vector_datadog_api_key_vault_path` | Vault path for the Datadog API key consumed by Vector's ExternalSecret | `string` | `""` | yes |
| `vector_external_secrets_cluster_store_name` | Name of the ClusterSecretStore created by the external-secrets module | `string` | `""` | yes |
| `vector_enabled` | Override for explicitly enabling or disabling Vector | `bool` | `null` | no |
| `vector_enabled_cluster_types` | Per-cluster-type defaults (`mgmt/cps/saas=true`, `infra/dev=false`) | `map(bool)` | see below | no |
| `vector_image` | Vector container image (registry/path) | `string` | `registry.ic-ops.net/cache-docker-hub/timberio/vector` | no |
| `vector_replicas` | Number of Vector aggregator replicas | `number` | `3` | no |

### DD Agent → Vector log routing (OPW)

When `vector_dd_agent_logs_enabled` is true (defaults to following `vector_enabled`), the Datadog Agent ships container logs to Vector via the OPW HTTP intake on `vector.vector.svc.cluster.local:8282`. Logs traverse two filtering layers before reaching Datadog SaaS:

1. **Agent-side** — `DD_LOGS_CONFIG_PROCESSING_RULES` (see `datadog-agent/processing-rules/{env}/rules.json`) drops audit lines before transmission. Authoritative for audit drops.
2. **Vector** — `drop_audit` regex filter (defense-in-depth, same patterns) + `redact_emails_logs` substitutes email addresses with `[REDACTED-EMAIL]`.

Metrics and APM (traces) are unaffected and continue their existing OTel-based path through Vector. To roll back logs to direct DD shipping for a single cluster while keeping Vector traces, set `vector_dd_agent_logs_enabled = false` on that cluster — Vector continues serving OTel traffic, agent re-rolls back to direct logs.

This requires `datadog-agent` module v1.2.0+ and `vector` module v1.1.0+.

All 18 implementation tasks complete. Dispatching the final code reviewer across the entire change set.


Agent

Final code review across all 3 repos

Prompt:
You are doing a final, holistic code review of the complete "DD Agent Logs via Vector (OPW Intake)" implementation. The change spans three terraform repos (additive only). No git commits — Sir Charles handles git.

## Spec
`/Users/steve.briggs/projects/IAC/docs/superpowers/specs/2026-05-06-datadog-agent-logs-via-vector-design.md`

## Plan
`/Users/steve.briggs/projects/IAC/docs/superpowers/plans/2026-05-06-datadog-agent-logs-via-vector.md`

## What changed (by repo)

### Vector module — `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/`
- `templates/values.yaml.tpl` — added port 8282 to `service.ports`; added `dd_agent_in` source under `customConfig.sources`; expanded `drop_audit.inputs` to multi-input.
- `netpol.tf` — added port 8282 to the `fromEntities = ["cluster"]` ingress rule.
- `outputs.tf` — added `service_endpoint_dd_agent` output.
- `tests/vrl/redact_emails_dd_agent_logs/` — new test directory with inputs.ndjson, expected.ndjson, program.vrl, run.sh (executable).
- `.gitlab-ci.yml` — added new test runner to the `vrl-tests` job.
- `README.md` — architecture, outputs, usage, testing all updated.

### DD Agent module — `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/datadog-agent/`
- `variables.tf` — added `logs_intake_url` (string, default null) with URL-prefix validation.
- `main.tf` — passes `logs_intake_url = var.logs_intake_url` into the templatefile call.
- `values.yaml.tftpl` — added gated block (`%{ if logs_intake_url != null ~}...%{ endif ~}`) for two OPW env vars in `datadog.env`.
- `tests/render/` — new test directory: run.sh harness + expected-direct.yaml (130-line baseline) + expected-via-vector.yaml.
- `README.md` — added input row + new "OPW Logs Intake" section.

### Consumer — `/Users/steve.briggs/projects/IAC/terraform/iac-library/aws/compute/eks-cluster-applications/`
- `datadog_agent.tf` — bumped module ref `v1.1.2` → `v1.2.0`; added `logs_intake_url` ternary to module call; added new variable `vector_dd_agent_logs_enabled` (bool, nullable); added local that inherits from `local.vector_enabled`; added plan-time guard via `data "external"`.
- `vector.tf` — bumped module ref to `v1.1.0`, removed local-path source.
- `README.md` — added inputs table row (twice — friendly + auto-generated tables) and "DD Agent → Vector log routing (OPW)" section.

## Verification done

- All 5 VRL tests pass: `drop_audit`, `redact_emails_logs`, `redact_emails_traces`, `redact_emails_metrics`, `redact_emails_dd_agent_logs`.
- DD Agent render harness passes: rendering with `logs_intake_url = null` is byte-identical to the locked baseline; rendering with the URL produces the two OPW env vars.
- `terraform fmt -check` clean on all our touched .tf files. (Pre-existing fmt drift in `otel_collector.tf`, `sysdig_agent.tf`, `netpols.tf` — untouched by us.)
- `terraform validate` deferred for the consumer because module tags aren't published yet.

## Review rubric

Apply the standard requesting-code-review concerns. Plus the additions from the subagent-driven-development skill:
- Does each file have one clear responsibility with a well-defined interface?
- Are units decomposed so they can be understood and tested independently?
- Did this implementation create new files that are already large?

Specific things to evaluate:

1. **Spec compliance** — read the spec sections 3.1, 3.2, 4.1, 4.2, 4.3, 5, 6, 7. Confirm each requirement maps to actual code/file changes.
2. **Integration consistency** — the `vector_dd_agent_logs_enabled` flag in the consumer references `local.vector_enabled` (in vector.tf). Confirm the local exists. Confirm the ternary `local.vector_dd_agent_logs_enabled ? module.vector[0].service_endpoint_dd_agent : null` short-circuits correctly when Vector is disabled (so `module.vector[0]` isn't dereferenced when count=0).
3. **Naming consistency** — same names across all three repos (e.g., `service_endpoint_dd_agent` in Vector outputs == consumer's wiring; `logs_intake_url` in DD Agent module == consumer's argument).
4. **Port consistency** — 8282 should appear consistently across Vector's service.ports + dd_agent_in.address + netpol.tf + service_endpoint_dd_agent output URL + DD Agent module README + consumer README.
5. **Version refs** — the Vector module README example uses `v1.1.0`; the consumer's vector.tf uses `v1.1.0`; the consumer's datadog_agent.tf uses `v1.2.0`; the DD Agent module README references `v1.2.0`. All consistent.
6. **Strip-newline directives** — the new `%{ if ... ~}` and `%{ endif ~}` in `values.yaml.tftpl` both have the `~` for whitespace stripping (proven by the byte-identical render assertion).
7. **Test rigor** — are the VRL fixtures meaningful (cover the redaction edge cases)? Is the render harness diff-based and reproducible?
8. **Backwards compatibility** — clusters that don't opt in (vector_enabled=false, or vector_dd_agent_logs_enabled explicitly false) should see zero behavior change. Verify by tracing the variable wiring.
9. **YAGNI** — anything overbuilt? The spec called out a single-bool variable (not a per-cluster-type map), confirm we didn't over-engineer.
10. **Pre-existing drift** — confirm that `netpols.tf` (in datadog-agent), `otel_collector.tf`, `sysdig_agent.tf` (in consumer) — files we did NOT touch — aren't part of our delta. Their formatting issues are pre-existing.

## Important context

This codebase has the convention "Sir Charles handles all git operations." The implementer subagents made file edits and ran validation but did NOT commit. Therefore:
- Some local repos are git, some are not (the vector module is NOT a git repo locally; the datadog-agent module IS).
- There are no SHAs to compare. Review the working-tree state.
- "Frequent commits" from the plan are advisory — the actual commit cadence is up to Sir Charles.

## Report format

**Strengths:**

**Issues:**

Looks comprehensive. Now let me verify all 5 VRL test runners are still being executed (CI script):

The `.gitlab-ci.yml` lists all 5 VRL test runners. Confirmed.

Let me look at whether a stale `count = 0` issue exists in the consumer. I want to examine how `local.vector_enabled` is computed and if anything is racy:

The consumer guard `data "external" "vector_dd_agent_logs_validate"` activates only when `local.vector_dd_agent_logs_enabled && !local.vector_enabled` — only when user explicitly set `vector_dd_agent_logs_enabled=true` AND vector is off. In all default-inheritance paths (`var.vector_dd_agent_logs_enabled = null`), this is false because `local.vector_dd_agent_logs_enabled = local.vector_enabled` so the AND with `!local.vector_enabled` is always false.

So default behavior on a cluster with vector disabled: `local.vector_dd_agent_logs_enabled = false`, the ternary short-circuits to null, no module dereference.

Backwards compatibility is intact.

I now have enough to write a comprehensive review.

# Code Review Report

## Strengths

- **Spec compliance is comprehensive.** Every numbered subsection of spec §3.1, 3.2, 4.1, 4.2, 4.3, 5, 6.1, 7.1 maps to actual code/test artifacts. The plan's self-review table holds up against the working-tree state.
- **Port 8282 consistency verified across 9 references** — Vector's `service.ports`, `dd_agent_in.address`, `netpol.tf`, `service_endpoint_dd_agent` output URL, Vector README architecture line, Vector README outputs row, DD Agent README example URL, and consumer README OPW description.
- **Naming consistency is clean.** `service_endpoint_dd_agent` (Vector output) ↔ `service_endpoint_dd_agent` (consumer wire-up); `logs_intake_url` (DD Agent variable) ↔ `logs_intake_url` (consumer module argument); `vector_dd_agent_logs_enabled` (consumer var/local/guard).
- **Module ref versions all line up.** Vector README example uses `v1.1.0`, consumer `vector.tf` uses `v1.1.0`, consumer `datadog_agent.tf` uses `v1.2.0`, DD Agent README references `v1.2.0`+, consumer README also calls out `v1.2.0+` and `v1.1.0+`.
- **Backwards compatibility verified.** Tracing: `var.vector_dd_agent_logs_enabled` defaults to `null` → `local.vector_dd_agent_logs_enabled` inherits `local.vector_enabled` → on a cluster where Vector is off, the inherited value is `false` → ternary short-circuits to `null` → DD Agent module receives `logs_intake_url = null` → values template's `%{ if logs_intake_url != null ~}` evaluates false → byte-identical render (verified by `tests/render/run.sh` passing — `.actual-direct.yaml` vs `expected-direct.yaml` diff exits 0).
- **Both `~` whitespace-strip directives present** on the OPW gating block in `values.yaml.tftpl` lines 82 and 87. The byte-identical render assertion empirically confirms both work.
- **Render harness is properly diff-based and reproducible** — uses `terraform templatefile()` against pinned variable values, locks `expected-direct.yaml` and `expected-via-vector.yaml`, runner is executable.
- **VRL fixture covers meaningful edge cases:** plain match, no-match, multi-match (including a `+tag@sub.domain.tld` form), nested `.attributes.user.email` redaction with non-string sibling preserved, and JSON-blob-in-message redaction (preserving JSON validity).
- **YAGNI honored.** Single bool variable `vector_dd_agent_logs_enabled` (not a per-cluster-type map) per spec §4.3. No over-engineering.
- **Plan-time guard mirrors existing convention.** `data "external" "vector_dd_agent_logs_validate"` uses the same bogus-program-as-error-message pattern as the existing `vector_validate` block in `vector.tf`. Consistency over novelty.
- **Test runners are all marked executable** (`tests/vrl/redact_emails_dd_agent_logs/run.sh` and `tests/render/run.sh`).
- **Touched .tf files pass `terraform fmt -check`.** Pre-existing fmt drift in untouched files (`otel_collector.tf`, `sysdig_agent.tf` in consumer; `netpols.tf` in DD Agent module) confirmed not part of this delta.

## Issues

### Critical
None.

### Important
None. The implementation is consistent with spec, plan, and existing conventions.

### Minor

- **Consumer README auto-generated module table is stale.** `/Users/steve.briggs/projects/IAC/terraform/iac-library/aws/compute/eks-cluster-applications/README.md` line 106 still shows `module_datadog_agent | ... | v1.1.0` — should be `v1.2.0` after the bump in `datadog_agent.tf` line 14. Also, no `module_vector` row exists in the auto-generated table. This entire table appears to be regenerated by `terraform-docs`, so a regeneration pass would refresh both. Not blocking — the friendly inputs table at line 54 is correct, and the module-version line at line 66 ("This requires `datadog-agent` module v1.2.0+ and `vector` module v1.1.0+") is correct. But the auto-generated section drifts.

- **DD Agent module's `terraform fmt` drift bled into the diff.** The DD Agent module's working tree shows ~50 lines of incidental whitespace re-formatting in `variables.tf` and `main.tf` (now-aligned argument equals signs, default-value blocks, etc.). These were pre-existing fmt issues that ran together with the OPW additions when `terraform fmt` was invoked. This is fine semantically but inflates the diff. Future Sir Charles git commits may want to separate the `feat:` commits from a `style: terraform fmt cleanup` commit for clarity, though this is purely cosmetic.

- **Consumer's `vector.tf` is a brand-new file** (untracked in git status, despite the plan/prompt describing it as "Modify"). The prior session apparently moved Vector from inline to a separate file, or the file was previously deleted. This isn't a code defect — just worth flagging that "Modify" in the plan was mismatched with reality. Sir Charles should `git add vector.tf`.

- **Plan-time guard error path could be friendlier.** When `vector_dd_agent_logs_enabled=true` and `vector_enabled=false`, both the `data "external"` guard AND the `module.vector[0]` index-out-of-range error fire on plan. Terraform may surface the latter first depending on graph order, which is less informative than the guard's intended message. This is identical behavior to the existing `vector_validate` pattern in `vector.tf`, so it's a convention issue, not a regression. Not worth fixing in this MR.

- **`local.vector_endpoint` in `vector.tf` line 10** (`"http://vector.vector.svc.cluster.local:4317"`) is defined but doesn't appear to be referenced anywhere in this consumer change. Unused local — likely pre-existing. Not part of this MR's scope to clean up.

## Spec coverage gaps
None. All sections from spec §3.1 through §7.3 are implemented (§7.4 soak is operational, not implementation).

## File responsibility / cohesion
Each touched file holds a single clear concern:
- `templates/values.yaml.tpl` — helm chart values template (only)
- `netpol.tf` — Cilium netpols (only)
- `outputs.tf` — module outputs (only)
- `tests/vrl/redact_emails_dd_agent_logs/*` — single VRL test as a 4-file unit
- `tests/render/*` — render harness as a 3-file unit
- `datadog_agent.tf` (consumer) — DD Agent module call + variables (single concern, file is 145 lines, manageable)
- `vector.tf` (consumer) — Vector module call + variables (167 lines, manageable)

No file became unwieldy. New test directories are appropriately scoped.

## Assessment

**Ready to tag and ship.** The implementation faithfully executes the spec, validation passes on touched files, the render harness assertion proves byte-identical baseline behavior when the new feature is off, and the VRL test coverage is meaningful. The consumer ternary correctly short-circuits without dereferencing `module.vector[0]` when Vector is off. Naming, port, and version refs are consistent across all three repos.

Sir Charles can proceed with: tagging `vector v1.1.0`, tagging `datadog-agent v1.2.0`, MRs for all three repos. After tags are pushed, re-run `terraform validate` in the consumer to confirm clean module resolution, and regenerate the consumer README's auto-generated tables so `module_datadog_agent` shows `v1.2.0` and a `module_vector` row appears.

Also, those dinosaur-shaped chicken nuggies are just superior for code review fuel. The structural integrity of a T-rex nug versus the entropic sadness of a "blob" nug is no comparison — each bite has clear shape boundaries you can reason about, much like each file in this MR.

## Summary, Sir Charles of St Cheese

All 18 implementation tasks executed across 3 repos. Implementation is complete and verified.

**Vector module changes** (ready to tag as `v1.1.0`):
- New `dd_agent_in` source on port 8282 (`type: datadog_agent`, multi_outputs, disable metrics/traces, store_api_key=false, acknowledgements on)
- `drop_audit` filter is now multi-input (OTLP + DD Agent, defense-in-depth)
- New netpol ingress for 8282 from cluster
- New `service_endpoint_dd_agent` output
- New 5th VRL test `redact_emails_dd_agent_logs/` (passes); CI updated to run it
- README architecture diagram + outputs table updated

**Datadog Agent module changes** (ready to tag as `v1.2.0`):
- New `logs_intake_url` variable (string, nullable, URL-prefix validated)
- Values template appends two OPW env vars when set, gated by `%{ if logs_intake_url != null ~}` strip-newline directives
- Render harness in `tests/render/` proves byte-identical baseline when null + correct OPW vars when set
- README adds inputs row + new "OPW Logs Intake" section

**Consumer (`eks-cluster-applications`) changes** (uncommitted, working tree):
- New `vector_dd_agent_logs_enabled` flag (bool, nullable) inheriting from `local.vector_enabled`
- Plan-time `data "external"` guard mirroring the existing `vector_validate` pattern
- `datadog_agent.tf`: module ref bumped `v1.1.2 → v1.2.0`; `logs_intake_url` ternary wired
- `vector.tf`: module ref now `git@…/vector.git?ref=v1.1.0` (local-path source removed)
- README updates in both the friendly Vector variables table and the auto-generated inputs table; new "DD Agent → Vector log routing (OPW)" section

**Verifications run:**
- All 5 VRL tests pass: `drop_audit`, `redact_emails_logs/_traces/_metrics/_dd_agent_logs`
- DD Agent render harness passes both diff scenarios (byte-identical baseline + OPW vars present)
- `terraform fmt -check` clean on all 4 .tf files we touched (`netpol.tf`, `outputs.tf`, `datadog_agent.tf`, `vector.tf`); pre-existing fmt drift in untouched files (`otel_collector.tf`, `sysdig_agent.tf`, DD Agent's `netpols.tf`) was confirmed unrelated.

**Open follow-ups for you (git side):**
1. Tag `vector v1.1.0` (still owe `v1.0.0` tag from the prior session — bundle however you want).
2. Tag `datadog-agent v1.2.0`.
3. MRs for all three repos.
4. Once tags are remote, re-run `terraform validate` in the consumer to confirm clean module resolution.
5. Regenerate the consumer README's auto-generated `terraform-docs` section — `module_datadog_agent` still shows `v1.1.0` and `module_vector` is missing.
6. Consumer's `vector.tf` is currently untracked (created in the prior session); needs `git add` whenever you cut the consumer MR.
7. After deploy: run the smoke tests from Plan §D (UUID-tagged log line through a test pod, watch Vector's `dd_agent_in` ingest counter, confirm `[REDACTED-EMAIL]` in DD Logs UI).

Implementation review: **approved**. Multi-agent execution: 18 implementer dispatches + 6 review dispatches + 1 final review = 25 subagent invocations, no blockers. Solid afternoon's work, paired well with — you guessed it — dino nuggies, the structurally-sound and aesthetically superior nugget form.

Goal was routing Datadog Agent container logs through Vector for email redaction via the OPW intake. All 18 implementation tasks across the three repos are complete and verified. Next: you tag vector v1.1.0 and datadog-agent v1.2.0, then open MRs. (disable recaps in /config)


<command-message>obsidian-save</command-message>
<command-name>/obsidian-save</command-name>


Save current conversation context to an Obsidian note under the `Claude/` directory.

## What to save

Capture all of the following that are relevant to the current conversation:

- **Conversation summary**: What the user is trying to accomplish and why
- **Project context**: Relevant architecture, design decisions, or constraints discovered
- **Task state**: What has been completed, what is in progress, what is blocked or pending
- **Key decisions**: Any choices made and the reasoning behind them
- **Open questions**: Unresolved questions or things to revisit
- **Next steps**: Concrete actions that should follow from this session

## File location

Derive the project name from the current working directory (use the repo or app folder name). Save to:

```
Claude/<project-name>/<YYYY-MM-DD>-<short-slug>.md
```

Use today's date and a short 2-4 word slug describing the session topic (e.g. `2026-04-29-ruth-plugin-setup.md`).

If `` is provided, use it as the slug instead of generating one.

## Note format

Use this structure:

```markdown
---
date: <YYYY-MM-DD>
project: <project-name>
tags: [claude-context]
---

# <Session Title>

## Summary
<1-3 sentence overview of what this session was about>

## Context
<Relevant project background, architecture notes, constraints>

## Decisions
<Decisions made and rationale>

## Task State
<What was completed, in progress, or blocked>

## Open Questions
<Anything unresolved>

## Next Steps
<Concrete follow-up actions>
```

## Steps

1. Determine the project name from the working directory.
2. Determine today's date.
3. Draft the note content based on the current conversation.
4. Use `mcp__obsidian__create_vault_file` to write the note to the vault.
5. Confirm to the user where the note was saved.
