You are implementing Task A1 of the "DD Agent Logs via Vector" plan.

## Task Description

Create a new VRL test directory with four files for verifying the email-redaction transform on Datadog-Agent-shape log events.

**Files to create:**
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/inputs.ndjson`
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/expected.ndjson`
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/program.vrl`
- `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/run.sh`

### Step 1: inputs.ndjson

Five DD-Agent-shape events (top-level `.message` string + DD-attached metadata: `ddtags`, `service`, `hostname`, sometimes `attributes`):

```
{"message": "user alice@example.com signed in", "ddtags": "env:prod,service:api", "service": "api", "hostname": "ip-10-0-1-23"}
{"message": "no email here", "ddtags": "env:prod", "service": "worker", "hostname": "ip-10-0-1-24"}
{"message": "multiple a@b.com and c.d+tag@sub.example.co.uk", "service": "api", "hostname": "ip-10-0-1-25"}
{"message": "ok", "attributes": {"user.email": "bob@x.io", "request.id": "abc-123"}, "ddtags": "env:staging", "service": "auth", "hostname": "ip-10-0-2-99"}
{"message": "json blob {\"email\":\"x@y.com\"}", "service": "api", "hostname": "ip-10-0-1-50"}
```

### Step 2: expected.ndjson

Emails in `.message` and string `.attributes.*` values become `[REDACTED-EMAIL]`. Metadata fields untouched. Object keys must be alphabetized (jq canonicalizes for diff):

```
{"ddtags": "env:prod,service:api", "hostname": "ip-10-0-1-23", "message": "user [REDACTED-EMAIL] signed in", "service": "api"}
{"ddtags": "env:prod", "hostname": "ip-10-0-1-24", "message": "no email here", "service": "worker"}
{"hostname": "ip-10-0-1-25", "message": "multiple [REDACTED-EMAIL] and [REDACTED-EMAIL]", "service": "api"}
{"attributes": {"request.id": "abc-123", "user.email": "[REDACTED-EMAIL]"}, "ddtags": "env:staging", "hostname": "ip-10-0-2-99", "message": "ok", "service": "auth"}
{"hostname": "ip-10-0-1-50", "message": "json blob {\"email\":\"[REDACTED-EMAIL]\"}", "service": "api"}
```

### Step 3: program.vrl

Identical to existing `redact_emails_logs/program.vrl` (the transform is source-agnostic; we want a per-source test):

```
email_re = r'[\w._%+\-]+@[\w.-]+\.[A-Za-z]{2,}'

if is_string(.message) {
  .message = replace(string!(.message), email_re, "[REDACTED-EMAIL]")
}

if is_object(.attributes) {
  attrs, _err = object(.attributes)
  if is_object(attrs) {
    .attributes = map_values(attrs) -> |v| {
      if is_string(v) { replace(string!(v), email_re, "[REDACTED-EMAIL]") } else { v }
    }
  }
}
.
```

### Step 4: run.sh (must be chmod +x)

```
#!/usr/bin/env bash
set -euo pipefail
DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
ACTUAL="$DIR/.actual.ndjson"
vector vrl -p "$DIR/program.vrl" -i "$DIR/inputs.ndjson" -q -o > "$ACTUAL"
diff -u <(jq -c . "$DIR/expected.ndjson") <(jq -c . "$ACTUAL")
echo "redact_emails_dd_agent_logs VRL OK"
```

### Step 5: Run the test, expect pass

```
cd /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector
./tests/vrl/redact_emails_dd_agent_logs/run.sh
```

Must print `redact_emails_dd_agent_logs VRL OK` and exit 0. If diff fails, the most likely cause is object-key ordering in expected.ndjson — `jq -c .` sorts keys alphabetically.

## Context

This is the first task of a multi-phase plan to wire Datadog Agent → Vector via the OPW intake protocol. The Vector module already has `redact_emails_logs`/`redact_emails_traces`/`redact_emails_metrics` VRL tests for OTLP-shape events; this task adds a per-source test for DD-Agent-shape events to lock in source-agnostic redaction behavior.

Sibling test patterns to mirror: `tests/vrl/redact_emails_logs/`, `tests/vrl/drop_audit/`. Use the same file naming and run.sh shape.

The VRL transform is byte-identical to the existing logs program — that's intentional, the transform doesn't care about the source. The test's value is asserting the behavior holds for DD-Agent-shape events with ddtags/service/hostname metadata that the OTLP test doesn't have.

## CRITICAL — No git operations

**Do NOT run any git commands. Do NOT `git add`, `git commit`, or `git push`.** Sir Charles handles all git operations himself per durable project policy. Make file edits, run validation, and report. Skip the "Commit" step in any plan reference — it's the user's responsibility, not yours.

## Your Job

1. Create the four files exactly as specified above.
2. Make run.sh executable (`chmod +x`).
3. Run the test (Step 5 above). Confirm it prints "redact_emails_dd_agent_logs VRL OK".
4. Self-review: re-read the four files, confirm content matches the spec.
5. Report back.

If the test fails because `vector` or `jq` aren't on PATH, that's a tooling issue — report as DONE_WITH_CONCERNS and we'll handle.

## Report Format

- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- Files created (with full paths)
- Test output (full output of run.sh)
- Self-review findings (any issues you fixed)
- Any concerns

Working directory for any cd commands: `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector`


I'll implement Task A1 by creating the four VRL test files and running the validation. Let me start by examining the existing test structure to understand the pattern.


Bash

find /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl -type f | head -20


Good. The test directory structure exists. Now let me check one of the existing tests to understand the exact pattern:


Error: EISDIR: illegal operation on a directory, read '/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_logs'


Let me read the individual files:


1	email_re = r'[\w._%+\-]+@[\w.-]+\.[A-Za-z]{2,}'
2
3	if is_string(.message) {
4	  .message = replace(string!(.message), email_re, "[REDACTED-EMAIL]")
5	}
6
7	if is_object(.attributes) {
8	  attrs, _err = object(.attributes)
9	  if is_object(attrs) {
10	    .attributes = map_values(attrs) -> |v| {
11	      if is_string(v) { replace(string!(v), email_re, "[REDACTED-EMAIL]") } else { v }
12	    }
13	  }
14	}
15	.
16


Perfect. Now let me check the run.sh pattern:


1	#!/usr/bin/env bash
2	set -euo pipefail
3	DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
4	ACTUAL="$DIR/.actual.ndjson"
5	vector vrl -p "$DIR/program.vrl" -i "$DIR/inputs.ndjson" -q -o > "$ACTUAL"
6	diff -u <(jq -c . "$DIR/expected.ndjson") <(jq -c . "$ACTUAL")
7	echo "redact_emails_logs VRL OK"
8


Now let me create the new test directory and files. First, I'll create the directory:


(Bash completed with no output)


Now let me create the inputs.ndjson file:


Write

{"message": "user alice@example.com signed in", "ddtags": "env:prod,service:api", "service": "api", "hostname": "ip-10-0-1-23"}
{"message": "no email here", "ddtags": "env:prod", "service": "worker", "hostname": "ip-10-0-1-24"}

{"message": "ok", "attributes": {"user.email": "bob@x.io", "request.id": "abc-123"}, "ddtags": "env:staging", "service": "auth", "hostname": "ip-10-0-2-99"}
{"message": "json blob {\"email\":\"x@y.com\"}", "service": "api", "hostname": "ip-10-0-1-50"}


File created successfully at: /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/inputs.ndjson (file state is current in your context — no need to Read it back)


Now let me create the expected.ndjson file with alphabetized keys:


{"ddtags": "env:prod,service:api", "hostname": "ip-10-0-1-23", "message": "user [REDACTED-EMAIL] signed in", "service": "api"}
{"ddtags": "env:prod", "hostname": "ip-10-0-1-24", "message": "no email here", "service": "worker"}
{"hostname": "ip-10-0-1-25", "message": "multiple [REDACTED-EMAIL] and [REDACTED-EMAIL]", "service": "api"}
{"attributes": {"request.id": "abc-123", "user.email": "[REDACTED-EMAIL]"}, "ddtags": "env:staging", "hostname": "ip-10-0-2-99", "message": "ok", "service": "auth"}
{"hostname": "ip-10-0-1-50", "message": "json blob {\"email\":\"[REDACTED-EMAIL]\"}", "service": "api"}

Now let me create the program.vrl file:


email_re = r'[\w._%+\-]+@[\w.-]+\.[A-Za-z]{2,}'

if is_string(.message) {
  .message = replace(string!(.message), email_re, "[REDACTED-EMAIL]")
}

if is_object(.attributes) {
  attrs, _err = object(.attributes)
  if is_object(attrs) {
    .attributes = map_values(attrs) -> |v| {
      if is_string(v) { replace(string!(v), email_re, "[REDACTED-EMAIL]") } else { v }
    }
  }
}
.


File created successfully at: /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/program.vrl (file state is current in your context — no need to Read it back)


Now let me create the run.sh file:


#!/usr/bin/env bash
set -euo pipefail
DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
ACTUAL="$DIR/.actual.ndjson"
vector vrl -p "$DIR/program.vrl" -i "$DIR/inputs.ndjson" -q -o > "$ACTUAL"
diff -u <(jq -c . "$DIR/expected.ndjson") <(jq -c . "$ACTUAL")
echo "redact_emails_dd_agent_logs VRL OK"


File created successfully at: /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/run.sh (file state is current in your context — no need to Read it back)


Now let me make run.sh executable:


Now let me run the test:


2026-05-06T16:21:36.544921Z  INFO vector::app: Log level is enabled. level="info"
redact_emails_dd_agent_logs VRL OK


Excellent! The test passed. Now let me verify the generated output by checking the .actual.ndjson file to ensure the transformation is correct:


1	{ "ddtags": "env:prod,service:api", "hostname": "ip-10-0-1-23", "message": "user [REDACTED-EMAIL] signed in", "service": "api" }
2	{ "ddtags": "env:prod", "hostname": "ip-10-0-1-24", "message": "no email here", "service": "worker" }
3	{ "hostname": "ip-10-0-1-25", "message": "multiple [REDACTED-EMAIL] and [REDACTED-EMAIL]", "service": "api" }
4	{ "attributes": { "request.id": "abc-123", "user.email": "[REDACTED-EMAIL]" }, "ddtags": "env:staging", "hostname": "ip-10-0-2-99", "message": "ok", "service": "auth" }
5	{ "hostname": "ip-10-0-1-50", "message": "json blob {\"email\":\"[REDACTED-EMAIL]\"}", "service": "api" }
6


Perfect! Let me verify each of the created files to confirm they match the specification:


1	{"message": "user alice@example.com signed in", "ddtags": "env:prod,service:api", "service": "api", "hostname": "ip-10-0-1-23"}
2	{"message": "no email here", "ddtags": "env:prod", "service": "worker", "hostname": "ip-10-0-1-24"}
3	{"message": "multiple a@b.com and c.d+tag@sub.example.co.uk", "service": "api", "hostname": "ip-10-0-1-25"}
4	{"message": "ok", "attributes": {"user.email": "bob@x.io", "request.id": "abc-123"}, "ddtags": "env:staging", "service": "auth", "hostname": "ip-10-0-2-99"}
5	{"message": "json blob {\"email\":\"x@y.com\"}", "service": "api", "hostname": "ip-10-0-1-50"}

5	vector vrl -p "$DIR/program.vrl" -i "$DIR/inputs.ndjson" -q -o > "$ACTUAL"
6	diff -u <(jq -c . "$DIR/expected.ndjson") <(jq -c . "$ACTUAL")
7	echo "redact_emails_dd_agent_logs VRL OK"
8


Perfect! Let me verify that run.sh is executable:

.rw-r--r-- steve.briggs staff 616 B Wed May  6 12:21:36 2026 .actual.ndjson


Perfect. Let me run the test one more time to confirm everything is working properly:


Bash

cd /Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector && ./tests/vrl/redact_emails_dd_agent_logs/run.sh 2>&1


2026-05-06T16:22:10.920603Z  INFO vector::app: Log level is enabled. level="info"
redact_emails_dd_agent_logs VRL OK


Excellent! All files have been created and tested successfully. Let me provide a summary.

---

## Status: DONE

### Files Created

1. `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/inputs.ndjson`
2. `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/expected.ndjson`
3. `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/program.vrl`
4. `/Users/steve.briggs/projects/IAC/terraform/internal-modules/kubernetes/monitoring/vector/tests/vrl/redact_emails_dd_agent_logs/run.sh` (executable)

### Test Output

```
2026-05-06T16:22:10.920603Z  INFO vector::app: Log level is enabled. level="info"
redact_emails_dd_agent_logs VRL OK
```

### Self-Review Findings

All four files match the specification exactly:

- **inputs.ndjson**: Five DD-Agent-shape events with `.message`, `ddtags`, `service`, `hostname`, and one with `.attributes`
- **expected.ndjson**: All email addresses replaced with `[REDACTED-EMAIL]` in both `.message` strings and nested `.attributes` string values; metadata fields (`ddtags`, `service`, `hostname`) unchanged; object keys alphabetically ordered
- **program.vrl**: Email regex transform applied to `.message` and `.attributes.*` string values; identical to existing `redact_emails_logs/program.vrl` (as intended—the transform is source-agnostic)
- **run.sh**: Follows the same pattern as existing tests; executable flag set; successfully runs `vector vrl`, applies the transform, canonicalizes JSON via `jq -c`, diffs against expected output

The test validates that the email-redaction VRL transform works correctly on Datadog Agent-shape events with DD-specific metadata, complementing the existing OTLP-shape tests. No concerns.
