feat(phase-2): workstream 8 — Multi-Region Terraform Deployment

AWS environment:
- VPC (3-AZ, public + private subnets, NAT gateways, VPC endpoints for ECR/SM/CW)
- ECS Fargate service (sentryagent/agentidp) — secrets from Secrets Manager
- RDS PostgreSQL 14 (Multi-AZ, encrypted, VPC-internal, storage autoscaling)
- ElastiCache Redis 7 (primary + replica, at-rest + in-transit encryption)
- ALB with HTTPS/443, HTTP→HTTPS redirect, ACM certificate
- Route 53 alias record

GCP environment:
- VPC + private services access + Serverless VPC connector
- Cloud Run service — secrets from Secret Manager
- Cloud SQL PostgreSQL 14 (private IP, no public endpoint)
- Cloud Memorystore Redis 7 (VPC-internal, AUTH enabled)

Shared:
- 4 reusable modules: agentidp (dual AWS/GCP), rds, redis, lb
- No hardcoded secrets; all sensitive vars marked sensitive=true
- terraform.tfvars.example for both environments

+## 1. Prerequisites
+
+### Tools
+
+| Tool | Minimum Version | Install |
+|------|-----------------|---------|
+| Terraform | 1.6.0 | https://developer.hashicorp.com/terraform/install |
+| AWS CLI | 2.13 | https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html |
+| gcloud CLI | 460.0 | https://cloud.google.com/sdk/docs/install |
+| Docker | 24.0 | Required only for building and pushing images |
+| openssl | any | Required for generating JWT key pairs |
+
+Verify all tools are available:
+
+```bash
+terraform version
+aws --version
+gcloud version
+docker version
+openssl version
+```
+
+### Container Image
+
+Build and push the `sentryagent/agentidp` image to your registry before deploying. Terraform references the image by tag — it does not build it.
+
+```bash
+# From the project root
+docker build -t sentryagent/agentidp:1.0.0 .
+
+# Push to your registry (ECR example):
+aws ecr get-login-password --region us-east-1 \
+  | docker login --username AWS --password-stdin 123456789012.dkr.ecr.us-east-1.amazonaws.com
+
+docker tag sentryagent/agentidp:1.0.0 \
+  123456789012.dkr.ecr.us-east-1.amazonaws.com/sentryagent/agentidp:1.0.0
+
+docker push 123456789012.dkr.ecr.us-east-1.amazonaws.com/sentryagent/agentidp:1.0.0
+```
+
+Update `app_image_tag` in your `terraform.tfvars` to match.
+
+### JWT Key Pair
+
+Generate the RSA-2048 key pair used for signing and verifying JWTs:
+
+```bash
+openssl genrsa -out jwt_private.pem 2048
+openssl rsa -in jwt_private.pem -pubout -out jwt_public.pem
+
+# Verify
+openssl rsa -in jwt_private.pem -check -noout
+```
+
+Keep `jwt_private.pem` secure — treat it with the same sensitivity as a TLS private key. You will paste its contents into `terraform.tfvars`.
+
+---
+
+## 2. AWS Deployment
+
+### 2.1 Configure AWS CLI
+
+```bash
+aws configure
+# Provide: AWS Access Key ID, Secret Access Key, region (e.g. us-east-1), output format (json)
+
+# Verify credentials
+aws sts get-caller-identity
+```
+
+The IAM principal running Terraform requires permissions to manage: VPC, ECS, RDS, ElastiCache, ALB, IAM roles, Secrets Manager, Route 53, CloudWatch, and VPC endpoints.
+
+### 2.2 Provision an ACM Certificate
+
+The ALB requires an ACM certificate for your domain. Create it in the same region as your deployment.
+
+```bash
+aws acm request-certificate \
+  --domain-name idp.example.com \
+  --validation-method DNS \
+  --region us-east-1
+```
+
+Complete DNS validation by adding the CNAME record shown in the ACM console. Wait for the status to become `ISSUED` before proceeding.
+
+```bash
+# Monitor validation status
+aws acm describe-certificate \
+  --certificate-arn arn:aws:acm:us-east-1:123456789012:certificate/XXXX \
+  --region us-east-1 \
+  --query 'Certificate.Status'
+```
+
+### 2.3 Prepare tfvars
+
+```bash
+cd terraform/environments/aws
+cp terraform.tfvars.example terraform.tfvars
+```
+
+Edit `terraform.tfvars`. All fields marked `REPLACE_WITH_*` are required. Key fields:
+
+- `region` — AWS region (must match the ACM certificate region)
+- `domain_name` — your domain (e.g. `idp.example.com`)
+- `certificate_arn` — ARN from step 2.2
+- `app_image_tag` — tag of the image you pushed in step 1
+- `db_password` — strong random password (no `@`, `#`, `?`, `/` characters — they break URL parsing)
+- `redis_auth_token` — minimum 16 characters, no spaces
+- `jwt_private_key` — full PEM contents of `jwt_private.pem` with literal `\n` for newlines
+- `jwt_public_key` — full PEM contents of `jwt_public.pem` with literal `\n` for newlines
+
+Example for encoding PEM keys in tfvars:
+
+```bash
+# Output the private key as a single line with \n separators (for pasting into tfvars)
+awk 'NF {printf "%s\\n", $0}' jwt_private.pem
+```
+
+**Never commit `terraform.tfvars` to version control.**
+
+### 2.4 Configure Remote State (Recommended)
+
+Uncomment and configure the `backend "s3"` block in `terraform/environments/aws/main.tf`:
+
+```hcl
+backend "s3" {
+  bucket         = "your-terraform-state-bucket"
+  key            = "agentidp/aws/production/terraform.tfstate"
+  region         = "us-east-1"
+  encrypt        = true
+  dynamodb_table = "your-terraform-locks-table"
+}
+```
+
+Create the S3 bucket and DynamoDB table if they do not exist:
+
+```bash
+# S3 bucket with versioning and encryption
+aws s3api create-bucket --bucket your-terraform-state-bucket --region us-east-1
+aws s3api put-bucket-versioning \
+  --bucket your-terraform-state-bucket \
+  --versioning-configuration Status=Enabled
+aws s3api put-bucket-encryption \
+  --bucket your-terraform-state-bucket \
+  --server-side-encryption-configuration \
+  '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"AES256"}}]}'
+
+# DynamoDB table for state locking
+aws dynamodb create-table \
+  --table-name your-terraform-locks-table \
+  --attribute-definitions AttributeName=LockID,AttributeType=S \
+  --key-schema AttributeName=LockID,KeyType=HASH \
+  --billing-mode PAY_PER_REQUEST \
+  --region us-east-1
+```
+
+### 2.5 Terraform Init
+
+```bash
+cd terraform/environments/aws
+terraform init
+```
+
+Expected output: provider plugins downloaded, backend initialized.
+
+### 2.6 Terraform Plan
+
+```bash
+terraform plan -out=tfplan
+```
+
+Review the plan carefully before applying. Expected resources on first apply: ~50–60 resources (VPC, subnets, NAT gateways, VPC endpoints, IAM roles, secrets, RDS, ElastiCache, ALB, ECS cluster, task definition, service, Route 53 record).
+
+### 2.7 Terraform Apply
+
+```bash
+terraform apply tfplan
+```
+
+**First apply takes 20–30 minutes** — RDS Multi-AZ provisioning is the longest step (~15 min). Do not interrupt the apply.
+
+When complete, note the outputs:
+
+```bash
+terraform output
+```
+
+Key outputs:
+- `service_url` — the HTTPS URL of your deployed service
+- `alb_dns_name` — ALB DNS name (verify Route 53 alias is pointing here)
+- `ecs_service_name` — use for ECS deployment commands
+- `cloudwatch_log_group` — where container logs appear
+
+### 2.8 Run Database Migrations
+
+After first deploy, run migrations against the new RDS instance. The easiest approach is to exec into a running ECS task:
+
+```bash
+# Get a running task ARN
+TASK_ARN=$(aws ecs list-tasks \
+  --cluster sentryagent-agentidp-production \
+  --service-name sentryagent-agentidp-production \
+  --query 'taskArns[0]' \
+  --output text)
+
+# Run migrations via ECS Exec (requires enableExecuteCommand on the service)
+aws ecs execute-command \
+  --cluster sentryagent-agentidp-production \
+  --task $TASK_ARN \
+  --container agentidp \
+  --command "node scripts/db-migrate.js" \
+  --interactive
+```
+
+Alternatively, run a one-off ECS task with the migration command as the container override.
+
+---
+
+## 3. GCP Deployment
+
+### 3.1 Configure gcloud CLI
+
+```bash
+gcloud auth login
+gcloud config set project your-gcp-project-id
+gcloud auth application-default login
+```
+
+Verify:
+
+```bash
+gcloud config list
+gcloud projects describe your-gcp-project-id
+```
+
+The principal running Terraform requires the following roles on the project:
+- `roles/owner` or a custom role covering: Cloud Run Admin, Cloud SQL Admin, Redis Admin, Secret Manager Admin, IAM Admin, Compute Admin, Service Networking Admin.
+
+### 3.2 Prepare tfvars
+
+```bash
+cd terraform/environments/gcp
+cp terraform.tfvars.example terraform.tfvars
+```
+
+Edit `terraform.tfvars`. Key fields:
+
+- `project_id` — your GCP project ID
+- `region` — GCP region (e.g. `us-central1`)
+- `app_image_tag` — tag of the image you built
+- `db_password` — strong random password for Cloud SQL
+- `jwt_private_key` / `jwt_public_key` — same PEM keys used for AWS (same key pair for both regions)
+
+**Never commit `terraform.tfvars` to version control.**
+
+### 3.3 Configure Remote State (Recommended)
+
+Uncomment and configure the `backend "gcs"` block in `terraform/environments/gcp/main.tf`:
+
+```hcl
+backend "gcs" {
+  bucket = "your-terraform-state-bucket"
+  prefix = "agentidp/gcp/production"
+}
+```
+
+Create the GCS bucket:
+
+```bash
+gsutil mb -l us-central1 gs://your-terraform-state-bucket
+gsutil versioning set on gs://your-terraform-state-bucket
+```
+
+### 3.4 Terraform Init
+
+```bash
+cd terraform/environments/gcp
+terraform init
+```
+
+### 3.5 Terraform Plan
+
+```bash
+terraform plan -out=tfplan
+```
+
+Review the plan. Expected resources: ~35–45 resources (VPC, subnet, VPC connector, service accounts, secrets, Cloud SQL, Memorystore, Cloud Run service, IAM bindings, API enablement).
+
+### 3.6 Terraform Apply
+
+```bash
+terraform apply tfplan
+```
+
+**First apply takes 15–20 minutes** — Cloud SQL provisioning is the longest step.
+
+When complete:
+
+```bash
+terraform output
+```
+
+Key outputs:
+- `service_url` — Cloud Run HTTPS URL (Google-managed TLS, no cert setup required)
+- `cloud_sql_connection_name` — for Cloud SQL Proxy if needed
+- `memorystore_host` — Redis private IP
+
+### 3.7 Run Database Migrations
+
+Cloud Run does not support exec. Use a one-off Cloud Run Job for migrations:
+
+```bash
+gcloud run jobs create agentidp-migrate \
+  --image sentryagent/agentidp:1.0.0 \
+  --region us-central1 \
+  --command node \
+  --args "scripts/db-migrate.js" \
+  --set-secrets "DATABASE_URL=sentryagent-agentidp-production-database-url:latest" \
+  --vpc-connector sentryagent-agentidp-production-connector \
+  --service-account sentryagent-agentidp-production-run-sa@your-gcp-project-id.iam.gserviceaccount.com
+
+gcloud run jobs execute agentidp-migrate --region us-central1 --wait
+```
+
+---
+
+## 4. Post-Deploy Verification
+
+Run these checks after deploying to either environment. Replace `https://idp.example.com` with your actual service URL.
+
+### 4.1 Health Check
+
+```bash
+curl -si https://idp.example.com/health
+```
+
+Expected response:
+
+```
+HTTP/2 200
+content-type: application/json
+
+{"status":"ok"}
+```
+
+If you receive a 502 or 503, the load balancer has not yet registered healthy targets. Wait 60–90 seconds and retry — ECS tasks or Cloud Run instances take time to pass health checks.
+
+### 4.2 Metrics Endpoint
+
+```bash
+curl -si https://idp.example.com/metrics
+```
+
+Expected: HTTP 200 with Prometheus-format metrics text (lines beginning with `# HELP`, `# TYPE`, and metric values).
+
+### 4.3 Token Endpoint (Smoke Test)
+
+First, register a test agent client (requires a valid JWT or admin credentials — see [developers guide](../developers/)):
+
+```bash
+# Issue a client credentials token (replace CLIENT_ID and CLIENT_SECRET with real values)
+curl -s -X POST https://idp.example.com/api/v1/token \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "grant_type=client_credentials&client_id=test-client&client_secret=test-secret&scope=read"
+```
+
+Expected response (abbreviated):
+
+```json
+{
+  "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...",
+  "token_type": "Bearer",
+  "expires_in": 3600,
+  "scope": "read"
+}
+```
+
+### 4.4 JWKS Endpoint
+
+```bash
+curl -si https://idp.example.com/.well-known/jwks.json
+```
+
+Expected: HTTP 200 with a JSON object containing a `keys` array with at least one RSA public key entry.
+
+### 4.5 TLS Verification
+
+```bash
+# Verify TLS certificate is valid and matches your domain
+curl -vI https://idp.example.com 2>&1 | grep -E "(SSL|TLS|certificate|issuer|subject)"
+```
+
+Expected: TLS 1.2 or 1.3, certificate issued by a trusted CA, subject matching your domain.
+
+### 4.6 AWS-Specific: ECS Service Status
+
+```bash
+aws ecs describe-services \
+  --cluster sentryagent-agentidp-production \
+  --services sentryagent-agentidp-production \
+  --query 'services[0].{desired:desiredCount,running:runningCount,pending:pendingCount,status:status}'
+```
+
+Expected: `running` equals `desired`, `status` is `ACTIVE`.
+
+### 4.7 GCP-Specific: Cloud Run Service Status
+
+```bash
+gcloud run services describe sentryagent-agentidp-production \
+  --region us-central1 \
+  --format='value(status.conditions[0].type,status.conditions[0].status)'
+```
+
+Expected: `Ready True`.
+
+---
+
+## 5. Rollback Procedure
+
+### 5.1 Image Rollback (Recommended — fastest)
+
+To roll back to a previous image tag without modifying infrastructure:
+
+**AWS:**
+
+```bash
+# Find the previous task definition revision
+aws ecs list-task-definitions \
+  --family-prefix sentryagent-agentidp-production \
+  --sort DESC \
+  --query 'taskDefinitionArns[:5]'
+
+# Update the service to use the previous task definition
+aws ecs update-service \
+  --cluster sentryagent-agentidp-production \
+  --service sentryagent-agentidp-production \
+  --task-definition sentryagent-agentidp-production:PREVIOUS_REVISION \
+  --force-new-deployment
+
+# Monitor the rollout
+aws ecs wait services-stable \
+  --cluster sentryagent-agentidp-production \
+  --services sentryagent-agentidp-production
+```
+
+**GCP:**
+
+```bash
+# Deploy the previous image tag directly
+gcloud run services update sentryagent-agentidp-production \
+  --region us-central1 \
+  --image sentryagent/agentidp:PREVIOUS_TAG
+
+# Or route 100% of traffic to a specific revision
+gcloud run services update-traffic sentryagent-agentidp-production \
+  --region us-central1 \
+  --to-revisions PREVIOUS_REVISION_NAME=100
+```
+
+### 5.2 Infrastructure Rollback via Terraform
+
+If an infrastructure change (not an image update) caused the problem:
+
+```bash
+# Check the state and plan to understand what changed
+terraform show
+terraform plan
+
+# If you have a previous state file (S3/GCS versioning), restore it:
+# AWS:
+aws s3 cp s3://your-state-bucket/agentidp/aws/production/terraform.tfstate.PREVIOUS ./terraform.tfstate
+terraform apply -target=<affected_resource>
+
+# GCP:
+gsutil cp gs://your-state-bucket/agentidp/gcp/production/PREVIOUS_VERSION ./terraform.tfstate
+terraform apply -target=<affected_resource>
+```
+
+**Never run `terraform destroy` in production without CEO approval.**
+
+### 5.3 Database Rollback
+
+RDS (AWS) and Cloud SQL (GCP) both support point-in-time restore. Use this only as a last resort — it creates a new DB instance and requires updating the `DATABASE_URL` secret.
+
+**AWS:**
+
+```bash
+# Restore to a point before the problematic deployment
+aws rds restore-db-instance-to-point-in-time \
+  --source-db-instance-identifier sentryagent-agentidp-production \
+  --target-db-instance-identifier sentryagent-agentidp-production-restored \
+  --restore-time 2026-01-01T12:00:00Z
+```
+
+**GCP:**
+
+```bash
+# List available backups
+gcloud sql backups list --instance sentryagent-agentidp-production-pg14
+
+# Restore from a backup
+gcloud sql backups restore BACKUP_ID \
+  --restore-instance sentryagent-agentidp-production-pg14
+```
+
+---
+
+## 6. Environment Variable Reference
+
+All environment variables injected into the AgentIdP container are documented in full at:
+
+**[docs/devops/environment-variables.md](./environment-variables.md)**
+
+### Quick Reference
+
+| Variable | Required | Source (AWS) | Source (GCP) |
+|----------|----------|--------------|--------------|
+| `DATABASE_URL` | Yes | Secrets Manager: `/<project>/<env>/database-url` | Secret Manager: `<name-prefix>-database-url` |
+| `REDIS_URL` | Yes | Secrets Manager: `/<project>/<env>/redis-url` | Secret Manager: `<name-prefix>-redis-url` |
+| `JWT_PRIVATE_KEY` | Yes | Secrets Manager: `/<project>/<env>/jwt-private-key` | Secret Manager: `<name-prefix>-jwt-private-key` |
+| `JWT_PUBLIC_KEY` | Yes | Secrets Manager: `/<project>/<env>/jwt-public-key` | Secret Manager: `<name-prefix>-jwt-public-key` |
+| `PORT` | No | Task definition env var (default: 3000) | Cloud Run env var (default: 3000) |
+| `NODE_ENV` | No | Task definition env var (`production`) | Cloud Run env var (`production`) |
+| `CORS_ORIGIN` | No | Task definition env var | Cloud Run env var |
+| `POLICY_DIR` | No | Task definition env var (`/app/policies`) | Cloud Run env var (`/app/policies`) |
+| `VAULT_ADDR` | No | Task definition env var | Cloud Run env var |
+| `VAULT_TOKEN` | No | Secrets Manager: `/<project>/<env>/vault-token` | Secret Manager: `<name-prefix>-vault-token` |
+| `VAULT_MOUNT` | No | Task definition env var (default: `secret`) | Cloud Run env var (default: `secret`) |
+
+### Updating a Secret
+
+**AWS:**
+
+```bash
+# Update a secret value (e.g. rotate JWT keys)
+aws secretsmanager put-secret-value \
+  --secret-id /sentryagent-agentidp/production/jwt-private-key \
+  --secret-string "$(cat new_jwt_private.pem)"
+
+# Force new ECS deployment to pick up the new secret value
+aws ecs update-service \
+  --cluster sentryagent-agentidp-production \
+  --service sentryagent-agentidp-production \
+  --force-new-deployment
+```
+
+**GCP:**
+
+```bash
+# Add a new version of a secret
+gcloud secrets versions add sentryagent-agentidp-production-jwt-private-key \
+  --data-file=new_jwt_private.pem
+
+# Deploy a new Cloud Run revision to pick up the latest secret version
+gcloud run services update sentryagent-agentidp-production \
+  --region us-central1 \
+  --image sentryagent/agentidp:CURRENT_TAG
+```
+
+---
+
+## Architecture Summary
+
+### AWS
+
+```
+Route 53 (A alias)
+  └── ALB (public subnets, HTTPS/443, ACM cert, HTTP→HTTPS redirect)
+        └── Target Group
+              └── ECS Fargate Service (private subnets, 2+ tasks)
+                    ├── Secrets Manager (DATABASE_URL, REDIS_URL, JWT keys)
+                    ├── RDS PostgreSQL 14 (private subnets, Multi-AZ, encrypted)
+                    └── ElastiCache Redis 7 (private subnets, primary+replica, TLS)
+```
+
+### GCP
+
+```
+Internet → Cloud Run Service (Google-managed TLS, auto-scaling)
+                    ├── Secret Manager (DATABASE_URL, REDIS_URL, JWT keys)
+                    ├── Serverless VPC Connector
+                    │     ├── Cloud SQL PostgreSQL 14 (private IP, REGIONAL HA)
+                    │     └── Memorystore Redis 7 (STANDARD_HA, TLS)
+```
+
+Both environments share the same Docker image (`sentryagent/agentidp`) and the same JWT key pair — tokens issued in one region are verifiable in the other.
