[Phase 2.2] Synthesis activities (5 activities) (#13 )

## Changes - `activity/synthesis.go` — 5 synthesis pipeline activities - `activity/synthesis_test.go` — 10 unit tests ## Activities 1. **ChunkAndEmbedActivity** — deterministic chunk ID + memory service ingest 2. **ExtractEntitiesActivity** — wiki-link, proper noun, technical term extraction 3. **ExtractFactsActivity** — 6 verb patterns with entity-boosted confidence 4. **DetectContradictionsActivity** — query + pre-filter + severity classification 5. **PersistSynthesisActivity** — save entities + facts to memory service ## Validation - 10 unit tests pass - `go build ./...` clean - Full suite: 35 packages pass, 0 failures --------- Co-authored-by: poimen <[email protected]> Reviewed-on: #13

-✅ temporal-elasticsearch-pvc: 20Gi (ReadWriteOnce)
-
-volumeMountPaths:
-  - PostgreSQL: /var/lib/postgresql/data

-
-## 6. Resource Limits
-
-### PostgreSQL
-
-```yaml
-requests:
-  cpu: 250m
-  memory: 512Mi
-limits:
-  cpu: 500m
-  memory: 1Gi

-
-## 7. Configuration Completeness
-
-### Temporal Server ConfigMap
-
-```yaml
-✅ Persistence: postgres (event log)
-✅ Visibility: postgres (search backend)
-✅ Elasticsearch: configured at http://temporal-elasticsearch:9200
-✅ NumHistoryShards: 4

-✅ 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

-# 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
