Phase 6.6: Add kmsvc Topic Creation (4 methods)

Topic Creation Methods:

1. Manual CLI (Fastest - 2 min):
   └─ kubectl port-forward + curl POST /v1/queues
   └─ k8s/config/create-kmsvc-topics.sh (interactive)

2. Kubernetes Job (Automated - 1 min):
   └─ kubectl apply kmsvc-topics-job.yaml
   └─ Runs once, creates topics if not exist
   └─ Can re-run safely

3. Terraform (IaC - 2 min):
   └─ terraform apply -target=null_resource.create_kmsvc_topics
   └─ Tracks topic creation in .tfstate
   └─ Idempotent

4. Shell Script (Interactive - 1 min):
   └─ ./create-kmsvc-topics.sh
   └─ Auto port-forward or manual mode
   └─ Color output + progress logging

Topics Created:

1. poimen-memory-dlq (DLQ for extraction + webhook + agent)
   ├─ Retention: 14 days (1,209,600 seconds)
   ├─ Visibility: 5 minutes (300 seconds)
   ├─ Messages: {id, type, workflow_id, error, timestamp, ...}
   └─ Consumer: queue_worker_dlq.rs::DlqHandler

2. poimen-memory-metric-dlq (DLQ for metrics failures)
   ├─ Retention: 14 days
   ├─ Visibility: 5 minutes
   ├─ Messages: {id, type, agent_id, error, timestamp, ...}
   └─ Consumer: (future) metrics replay handler

Files Added:

1. k8s/config/create-kmsvc-topics.sh (executable)
   ├─ 90 lines
   ├─ Auto port-forward + retry logic
   ├─ Color output + error handling
   └─ Usage: ./create-kmsvc-topics.sh [manual]

2. k8s/config/kmsvc-topics-job.yaml (Kubernetes)
   ├─ Job resource (one-time execution)
   ├─ Uses curl container
   ├─ Waits for management-service readiness
   ├─ 30-second retry loop
   └─ Non-fatal on existing topics

3. k8s/config/terraform-kmsvc-topics.tf (Terraform)
   ├─ null_resource with local-exec
   ├─ Variables for endpoint + namespace
   ├─ Idempotent + traceable
   └─ Outputs: created_topics + test_commands

4. docs/PHASE_6_6_KMSVC_TOPICS.md (Complete Guide)
   ├─ Table of topics + config
   ├─ 4 creation methods with examples
   ├─ Verification commands
   ├─ Message format specs
   ├─ Monitoring + alerts
   ├─ Troubleshooting guide
   └─ Next steps checklist

Verification Commands:

✅ List all topics:
   curl http://localhost:8080/v1/queues

✅ Check specific topic:
   curl http://localhost:8080/v1/queues/poimen-memory-dlq

✅ Send test message:
   curl -X POST http://localhost:8080/v1/queues/poimen-memory-dlq/messages      -H "Content-Type: application/json"      -d '{"body": "{\"type\": \"test\"}"}'

✅ Receive messages:
   curl -X POST http://localhost:8080/v1/queues/poimen-memory-dlq/messages/receive      -H "Content-Type: application/json"      -d '{"maxNumberOfMessages": 10}'

Integration Points:

Phase 6.6 Code → kmsvc Topics:

1. webhook_executor.rs::send_dlq_message()
   └─ On max retries: Send to poimen-memory-dlq
   └─ Payload: {workflow_id, webhook_url, status, error, ...}

2. metrics_persistence.rs::send_persistence_dlq()
   └─ On DB failure: Send to poimen-memory-metric-dlq
   └─ Payload: {agent_id, error, timestamp}

3. queue_worker_dlq.rs::DlqHandler
   └─ Processes poimen-memory-dlq messages
   └─ Retries extraction failures

Production Checklist:

✅ Topics defined (2 topics)

+# Phase 6.6: kmsvc Topic Creation Guide
+
+## Topics
+
+| Topic Name | Purpose | Retention | Visibility Timeout |
+|-----------|---------|-----------|-------------------|
+| `poimen-memory-dlq` | Extraction, webhook, agent failures | 14 days (1,209,600s) | 5 min (300s) |
+| `poimen-memory-metric-dlq` | Metrics persistence failures | 14 days | 5 min |
+
+## Methods to Create Topics
+
+### Method 1: Manual via CLI (Fastest)
+
+```bash
+# Port-forward to management-service
+kubectl -n sqs port-forward svc/management-service 8080:8080 &
+
+# Create poimen-memory-dlq
+curl -X POST http://localhost:8080/v1/queues \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "poimen-memory-dlq",
+    "fifoQueue": false,
+    "visibilityTimeoutSeconds": 300,
+    "messageRetentionPeriodSeconds": 1209600
+  }'
+
+# Create poimen-memory-metric-dlq
+curl -X POST http://localhost:8080/v1/queues \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "poimen-memory-metric-dlq",
+    "fifoQueue": false,
+    "visibilityTimeoutSeconds": 300,
+    "messageRetentionPeriodSeconds": 1209600
+  }'
+
+# Verify topics were created
+curl http://localhost:8080/v1/queues | jq
+```
+
+### Method 2: Kubernetes Job (Automated)
+
+```bash
+# Deploy the job (creates topics automatically)
+kubectl apply -f k8s/config/kmsvc-topics-job.yaml
+
+# Watch job progress
+kubectl -n poimen logs -f job/create-poimen-memory-kmsvc-topics
+
+# Verify job completed
+kubectl -n poimen get job create-poimen-memory-kmsvc-topics
+```
+
+### Method 3: Terraform (IaC)
+
+```bash
+# Navigate to config directory
+cd k8s/config
+
+# Initialize Terraform
+terraform init
+
+# Create topics
+terraform apply -target=null_resource.create_kmsvc_topics \
+  -var="management_service_endpoint=http://localhost:8080"
+
+# Verify creation
+curl http://localhost:8080/v1/queues | jq
+```
+
+### Method 4: Shell Script (Interactive)
+
+```bash
+# Make script executable
+chmod +x k8s/config/create-kmsvc-topics.sh
+
+# Run with auto port-forward
+./k8s/config/create-kmsvc-topics.sh
+
+# Or manual port-forward
+./k8s/config/create-kmsvc-topics.sh manual
+```
+
+## Verification
+
+### List all queues
+```bash
+curl http://localhost:8080/v1/queues | jq
+```
+
+### Check specific queue exists
+```bash
+curl http://localhost:8080/v1/queues/poimen-memory-dlq | jq
+```
+
+### Send test message to DLQ
+```bash
+curl -X POST http://localhost:8080/v1/queues/poimen-memory-dlq/messages \
+  -H "Content-Type: application/json" \
+  -d '{
+    "body": "{\"type\": \"test\", \"workflow_id\": \"test-123\"}"
+  }'
+```
+
+### Receive messages from DLQ
+```bash
+curl -X POST http://localhost:8080/v1/queues/poimen-memory-dlq/messages/receive \
+  -H "Content-Type: application/json" \
+  -d '{"maxNumberOfMessages": 10}'
+```
+
+## Queue Configuration Details
+
+### poimen-memory-dlq
+
+**Used by**:
+- Extraction failures (contradiction detection, validation)
+- Webhook execution failures (after all retries)
+- Agent initialization failures
+
+**Message Format**:
+```json
+{
+  "id": "uuid",
+  "type": "extraction_failure|webhook_failure|agent_failure",
+  "workflow_id": "wf-123",
+  "webhook_url": "http://...",
+  "error": "error message",
+  "timestamp": "2025-01-30T10:00:00Z",
+  "retry_count": 0,
+  "max_retries": 3,
+  "topic": "poimen-memory-dlq"
+}
+```
+
+**Processing**:
+- Consumer: `queue_worker_dlq.rs::DlqHandler`
+- Retry policy: Up to 3 retries via exponential backoff
+- TTL: 14 days (can be re-processed manually)
+
+### poimen-memory-metric-dlq
+
+**Used by**:
+- Metrics persistence failures (DB down, connection errors)
+
+**Message Format**:
+```json
+{
+  "id": "uuid",
+  "type": "metrics_persistence_failure",
+  "agent_id": "agent-123",
+  "error": "DB connection failed",
+  "timestamp": "2025-01-30T10:00:00Z",
+  "topic": "poimen-memory-metric-dlq"
+}
+```
+
+**Processing**:
+- Consumer: `metrics_persistence.rs::send_persistence_dlq()`
+- Retry policy: Manual intervention or scheduled replay
+- TTL: 14 days (allows recovery window)
+
+## Connection Pooling
+
+If using kmsvc producer client in Rust:
+
+```rust
+use rdkafka::producer::FutureProducer;
+use rdkafka::ClientConfig;
+
+let producer: FutureProducer = ClientConfig::new()
+    .set("bootstrap.servers", "kafka.sqs.svc.cluster.local:9092")
+    .set("client.id", "poimen-memory-producer")
+    .create()
+    .expect("Producer creation failed");
+
+// Send message to DLQ
+producer
+    .send(
+        FutureRecord::to("poimen-memory-dlq")
+            .key(&workflow_id)
+            .payload(&dlq_message),
+        Duration::from_secs(30),
+    )
+    .await?;
+```
+
+## Monitoring
+
+### Prometheus Metrics
+
+```
+# Messages sent to DLQ
+dlq_messages_sent_total{topic="poimen-memory-dlq"} 5
+dlq_messages_sent_total{topic="poimen-memory-metric-dlq"} 2
+
+# Message lag
+dlq_consumer_lag{topic="poimen-memory-dlq"} 0
+```
+
+### Alerts
+
+Set up alerts if:
+- DLQ message lag > 100 (backlog accumulating)
+- DLQ message rate > 10/min (high failure rate)
+- DLQ messages older than 7 days (not being processed)
+
+## Troubleshooting
+
+### Topic already exists error
+```bash
+# This is OK - it means the topic was already created
+# You can safely ignore this error
+
+# To force recreation, delete first:
+curl -X DELETE http://localhost:8080/v1/queues/poimen-memory-dlq
+```
+
+### Connection refused to management-service
+```bash
+# Verify port-forward is running
+ps aux | grep "port-forward.*management-service"
+
+# Check service is running
+kubectl -n sqs get svc management-service
+
+# Restart port-forward
+pkill -f "port-forward.*management-service"
+kubectl -n sqs port-forward svc/management-service 8080:8080 &
+```
+
+### Topics not appearing in list
+```bash
+# Verify topic creation response was successful
+curl -v -X POST http://localhost:8080/v1/queues \
+  -H "Content-Type: application/json" \
+  -d '{"name": "test-topic", "fifoQueue": false}'
+
+# Check for HTTP 200/201 response
+# If 400/409, check error message
+```
+
+## Next Steps
+
+1. ✅ Create topics via one of the methods above
+2. ✅ Verify topics exist with `curl http://localhost:8080/v1/queues`
+3. ✅ Deploy memory service (will start sending DLQ messages on failures)
+4. ⏳ Monitor DLQ message rate + latency
+5. ⏳ Set up consumer group for DLQ replay
+6. ⏳ Add alerting for DLQ backlog (Phase 7)
