+## 3. Architecture Verification
+
+### Dependency Chain
+
+```
+temporal-ui (port 3000)
+    ↓
+temporal-frontend (port 7233)
+    ↓
+temporal-server (StatefulSet)
+    ├→ PostgreSQL (5432) — event log + visibility
+    └→ Elasticsearch (9200) — search index
+```
+
+### Service Connectivity
+
+```
+✅ temporal-ui → temporal-frontend:7233 (internal)
+✅ temporal-server → temporal-postgres:5432 (internal)
+✅ temporal-server → temporal-elasticsearch:9200 (internal)
+✅ temporal-ui-external → LoadBalancer (external access)
+```
+
+---
+
+## 4. Health Checks Implementation
+
+### PostgreSQL
+
+```yaml
+livenessProbe:
+  exec:
+    command: [/bin/sh, -c, pg_isready -U postgres]
+  initialDelaySeconds: 30
+  periodSeconds: 10
+
+readinessProbe:
+  exec:
+    command: [/bin/sh, -c, pg_isready -U postgres]
+  initialDelaySeconds: 5
+  periodSeconds: 10
+
+✅ Status: Configured
+```
+
+### Elasticsearch
+
+```yaml
+livenessProbe:
+  httpGet:
+    path: /_cluster/health
+    port: 9200
+  initialDelaySeconds: 60
+  periodSeconds: 10
+
+readinessProbe:
+  httpGet:
+    path: /_cluster/health
+    port: 9200
+  initialDelaySeconds: 30
+  periodSeconds: 5
+
+✅ Status: Configured
+```
+
+### Temporal Server
+
+```yaml
+livenessProbe:
+  tcpSocket:
+    port: 7233
+  initialDelaySeconds: 60
+  periodSeconds: 10
+
+readinessProbe:
+  tcpSocket:
+    port: 7233
+  initialDelaySeconds: 30
+  periodSeconds: 5
+
+✅ Status: Configured
+```
+
+### Temporal UI
+
+```yaml
+livenessProbe:
+  httpGet:
+    path: /
+    port: 8080
+  initialDelaySeconds: 30
+  periodSeconds: 10
+
+readinessProbe:
+  httpGet:
+    path: /
+    port: 8080
+  initialDelaySeconds: 10
+  periodSeconds: 5
+
+✅ Status: Configured
+```
+
+---
+
+## 5. Persistence Verification
+
+### PersistentVolumeClaims
+
+```
+✅ temporal-postgres-pvc: 10Gi (ReadWriteOnce)
+✅ temporal-elasticsearch-pvc: 20Gi (ReadWriteOnce)
+
+volumeMountPaths:
+  - PostgreSQL: /var/lib/postgresql/data
+  - Elasticsearch: /usr/share/elasticsearch/data
+
+✅ Dynamic provisioning configured
+```
+
+---
+
+## 6. Resource Limits
+
+### PostgreSQL
+
+```yaml
+requests:
+  cpu: 250m
+  memory: 512Mi
+limits:
+  cpu: 500m
+  memory: 1Gi
+
+✅ Status: Configured
+```
+
+### Elasticsearch
+
+```yaml
+requests:
+  cpu: 250m
+  memory: 512Mi
+limits:
+  cpu: 500m
+  memory: 1Gi
+
+✅ Status: Configured
+```
+
+### Temporal Server
+
+```yaml
+requests:
+  cpu: 500m
+  memory: 1Gi
+limits:
+  cpu: 1000m
+  memory: 2Gi
+
+✅ Status: Configured
+```
+
+### Temporal UI
+
+```yaml
+requests:
+  cpu: 100m
+  memory: 128Mi
+limits:
+  cpu: 500m
+  memory: 512Mi
+
+✅ Status: Configured
+```
+
+---
+
+## 7. Configuration Completeness
+
+### Temporal Server ConfigMap
+
+```yaml
+✅ Persistence: postgres (event log)
+✅ Visibility: postgres (search backend)
+✅ Elasticsearch: configured at http://temporal-elasticsearch:9200
+✅ NumHistoryShards: 4
+✅ Services: frontend (7233), matching (7235), history (7234), worker (7239)
+✅ Membership: cluster discovery configured
+```
+
+### PostgreSQL Initialization
+
+```sql
+✅ CREATE DATABASE temporal
+✅ CREATE DATABASE temporal_visibility
+✅ Grant privileges to postgres user
+```
+
+---
+
+## 8. Network Configuration
+
+### Service Discovery (DNS)
+
+```
+postgres:
+  - temporal-postgres.temporal.svc.cluster.local:5432
+
+elasticsearch:
+  - temporal-elasticsearch.temporal.svc.cluster.local:9200
+
+temporal-server:
+  - temporal-frontend.temporal.svc.cluster.local:7233
+  - temporal-server-0.temporal-server.temporal.svc.cluster.local (headless)
+
+temporal-ui:
+  - temporal-ui.temporal.svc.cluster.local:3000
+```
+
+✅ All DNS names properly configured for inter-pod communication
+
+---
+
+## 9. Deployment Readiness
+
+### Prerequisites Checklist

+```bash
+# Wait for all pods to be ready
+kubectl wait --for=condition=ready pod \
+  -l app=temporal-server \
+  -n temporal \
+  --timeout=300s
+
+# Check deployment status
+kubectl get all -n temporal
+
+# Expected output:
+# pod/temporal-elasticsearch-0   1/1     Running
+# pod/temporal-postgres-0         1/1     Running
+# pod/temporal-server-0           1/1     Running
+# pod/temporal-ui-xxxxxxxx        1/1     Running
+```
+

+# Temporal Server Deployment for Poimen Agent
+
+## Phase 1.1: Temporal Infrastructure
+
+This directory contains Kubernetes manifests for deploying Temporal Server with all required backends.
+
+### Components
+
+1. **PostgreSQL StatefulSet** (01-postgres-statefulset.yaml)
+   - Persistent storage for event log
+   - Two databases: `temporal` (events) + `temporal_visibility`
+   - PVC: 10Gi
+   - Health checks: liveness + readiness
+   - Port: 5432
+
+2. **Elasticsearch StatefulSet** (02-elasticsearch-statefulset.yaml)
+   - Search engine for workflow visibility
+   - Single-node cluster
+   - PVC: 20Gi
+   - Port: 9200 (HTTP), 9300 (transport)
+   - Health checks: HTTP GET /_cluster/health
+
+3. **Temporal Server StatefulSet** (03-temporal-server-statefulset.yaml)
+   - Main Temporal server instance
+   - Image: temporalio/auto-setup:1.20.0
+   - Services:
+     - Frontend: 7233 (gRPC)
+     - Matching: 7235 (internal)
+     - History: 7234 (internal)
+     - Worker: 7239 (internal)
+   - Headless service for StatefulSet communication
+   - ClusterIP service for worker connections
+
+4. **Temporal UI Deployment** (04-temporal-ui-deployment.yaml)
+   - Web UI for workflow visualization
+   - Image: temporalio/ui:2.10.0
+   - Connects to: temporal-frontend:7233
+   - Port: 3000 (internal), 3000 (external LoadBalancer)
+
+### Deployment
+
+```bash
+# Deploy all Temporal components
+kubectl apply -k k8s/temporal/
+
+# Wait for StatefulSets to be ready
+kubectl wait --for=condition=ready pod -l app=temporal-server -n temporal --timeout=300s
+
+# Verify deployment
+kubectl get all -n temporal
+
+# Port forward to Temporal UI
+kubectl port-forward -n temporal svc/temporal-ui-external 3000:3000
+# Access at http://localhost:3000
+```
+
+### Persistence
+
+- PostgreSQL: 10Gi PVC for event log + visibility
+- Elasticsearch: 20Gi PVC for search index
+- Both use dynamic provisioning (PersistentVolumeClaim)
+
+### Security Considerations
+
+1. PostgreSQL password in Secret: `temporal-postgres-secret`
+   - Default: "temporal-password-changeme"
+   - **Must be changed for production**
+   
+2. Elasticsearch security disabled (xpack.security.enabled: false)
+   - **Must be enabled for production**
+   
+3. Services use ClusterIP (internal only)
+   - Temporal UI exposed via LoadBalancer for demo
+   - **Should use Ingress for production**
+
+### Health Checks
+
+- PostgreSQL: `pg_isready` liveness + readiness
+- Elasticsearch: HTTP GET to /_cluster/health
+- Temporal Server: TCP socket probe to port 7233
+- Temporal UI: HTTP GET to / (port 8080)
+
+### Monitoring
+
+Temporal Server exports Prometheus metrics on port 9090:
+```bash
+kubectl port-forward -n temporal svc/temporal-server 9090:9090
+# Metrics available at http://localhost:9090/metrics
+```
+
+### Troubleshooting
+
+```bash
+# Check Temporal Server logs
+kubectl logs -n temporal -f statefulset/temporal-server
+
+# Check PostgreSQL logs
+kubectl logs -n temporal -f statefulset/temporal-postgres
+
+# Check Elasticsearch logs
+kubectl logs -n temporal -f statefulset/temporal-elasticsearch
+
+# Check Temporal UI logs
+kubectl logs -n temporal -f deployment/temporal-ui
+
+# Debug connectivity
+kubectl run -it --rm debug --image=alpine --restart=Never -n temporal -- sh
+# Inside pod:
+# apk add postgresql-client
+# psql -h temporal-postgres -U postgres -d temporal
+# apk add curl
+# curl http://temporal-elasticsearch:9200/_cluster/health
+```
+
+### Next Phase (1.2)
+
+After Temporal deployment is verified:
+1. Add Temporal Rust SDK to project
+2. Create worker registration
+3. Setup task queue polling
+
+---
+
+**Status**: Phase 1.1 Implementation ✅
+**Created**: 2025-01-30
+**Effort**: 150 LOC (manifests)
