You are doing a combined spec + code quality review for Task A3 of the "DD Agent Logs via Vector" plan.

## What was requested

Three discrete changes in `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/templates/values.yaml.tpl`:

1. **Add port 8282 to `service.ports`**: a third entry `{ name: dd-agent, port: 8282, protocol: TCP }` after the existing otlp-grpc/otlp-http ports.
2. **Add `dd_agent_in` source under `customConfig.sources`** as a sibling to `otlp_in`. Required fields:
   - `type: datadog_agent`
   - `address: 0.0.0.0:8282`
   - `multiple_outputs: true`
   - `disable_metrics: true`
   - `disable_traces: true`
   - `store_api_key: false`
   - `acknowledgements: { enabled: true }`
3. **Update `drop_audit.inputs`** to be multi-input — current single entry `- otlp_in.logs` becomes a two-entry list `- otlp_in.logs` + `- dd_agent_in.logs`.

Nothing else in the file should be modified. The rest of the template (`role`, `replicas`, `podAnnotations`, `env`, `resources`, `podDisruptionBudget`, `topologySpreadConstraints`, `affinity`, `serviceMonitor` block, the rest of `customConfig`, all `transforms` and `sinks` other than the `drop_audit.inputs` change, all `%{ if ... ~}` directives) must be untouched.

## Verify

1. Read `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/templates/values.yaml.tpl` in full.
2. Confirm all three changes are present with correct YAML indentation:
   - `service.ports` list now has 3 entries; `dd-agent` is the third with port 8282 and protocol TCP. List items use 4-space indent (4 leading spaces before `-`); fields under each item use 6-space indent.
   - `customConfig.sources` has both `otlp_in` and `dd_agent_in`. The `dd_agent_in:` key uses 4-space indent (matching `otlp_in:`); its fields use 6-space indent; `acknowledgements.enabled` uses 8-space indent (under acknowledgements).
   - `drop_audit.inputs` has both `- otlp_in.logs` and `- dd_agent_in.logs` (8-space indent for the dashes).
3. Confirm nothing else changed.
4. **Skip terraform validate** — local terraform is v1.3.10 but the module example is pinned to a higher minor; this is an environmental issue, not a code issue. The YAML correctness is what we're verifying here.

## Code quality concerns (in addition to spec)

- Are the new keys clear and accurate (does `dd-agent` clearly identify the port purpose; do the source field names match Vector's documented `datadog_agent` source)?
- Indentation consistent with surrounding YAML?
- No accidental whitespace/trailing-spaces introduced?
- Did this change inadvertently bloat the file or split logic that should stay together? (Expected: ~+15 lines, all clustered.)

Report:
- ✅ Compliant + quality clean
- ❌ Issues found: [specifics with line numbers]

## Review Result: A3 — DD Agent Logs via Vector

**Overall: COMPLIANT + QUALITY CLEAN**

### Change 1 — `service.ports` third entry (lines 15–17)

```
    - name: dd-agent      # 4-space indent before '-'
      port: 8282           # 6-space indent for fields
      protocol: TCP
```

All three spec fields present (`name: dd-agent`, `port: 8282`, `protocol: TCP`). Indentation is byte-exact to the two preceding port entries (lines 9–14). No issues.

### Change 2 — `dd_agent_in` source (lines 69–77)

```
    dd_agent_in:           # 4-space indent, matches otlp_in:
      type: datadog_agent  # 6-space indent for fields
      address: 0.0.0.0:8282
      multiple_outputs: true
      disable_metrics: true
      disable_traces: true
      store_api_key: false
      acknowledgements:
        enabled: true      # 8-space indent under acknowledgements
```

All seven spec fields present with correct values. Indentation is byte-exact and consistent with `otlp_in`. The `acknowledgements.enabled` nesting is at 8-space as required. No issues.

### Change 3 — `drop_audit.inputs` dual entries (lines 82–83)

```
        - otlp_in.logs     # 8-space indent
        - dd_agent_in.logs # 8-space indent
```

Both entries present, indentation matches surrounding YAML context. No issues.

### Code quality findings

- **Naming clarity**: `dd-agent` as the port name is unambiguous given the service context. `dd_agent_in` as the source name is consistent with the existing `otlp_in` naming convention. Both are clear.
- **Field accuracy**: `datadog_agent` is the correct Vector source type name. `multiple_outputs: true`, `disable_metrics: true`, `disable_traces: true`, `store_api_key: false`, `acknowledgements.enabled: true` are all documented fields for this source type. Nothing invented.
- **Trailing whitespace**: None found on any line.
- **Tabs**: None found; all indentation is spaces throughout.
- **File size**: 174 lines total. Previous baseline (pre-change) would have been approximately 159 lines, making the delta ~+15 lines — exactly as expected. No bloat, no scattered changes.
- **Logic cohesion**: The new source block is grouped with its sibling `otlp_in` inside `sources:`, and the `drop_audit.inputs` update is the only transform touched, as specified. Nothing else was disturbed.

All three changes are present, correct, and clean.
