<objective>
Set up the Mill build system and create a working ZIO HTTP server with health endpoints and HOCON configuration.
Purpose: Establish the foundational build infrastructure and prove the ZIO HTTP stack works before adding database complexity.
Output: Running HTTP server accessible at localhost:8080 with /health endpoint.

Create Mill build file with Scala 3 and ZIO dependencies.
Use programmatic Mill config (build.mill not YAML) for assembly support:
- Scala version: 3.3.4 (LTS, better library compatibility than 3.8.x)
- Dependencies:
- dev.zio::zio:2.1.14
- dev.zio::zio-http:3.0.1 (stable release, not 3.8.x which is unreleased)
- dev.zio::zio-config:4.0.2

- org.postgresql:postgresql:42.7.4
- org.flywaydb:flyway-core:10.21.0
- org.flywaydb:flyway-database-postgresql:10.21.0
Include assembly configuration for fat JAR with:
- Service file merging for META-INF/services
- Exclude signature files (*.SF, *.DSA, *.RSA)
Note: Research suggested newer versions but use stable releases that exist on Maven Central.

src/db/QuillContext.scala:

- Export combined layer: dataSourceLayer >>> quillLayer
IMPORTANT: Never use "io" as a variable name in this file (Quill package conflict).
Configuration note: Quill reads HikariCP config from the "database" prefix in application.conf.
The existing database config structure should work, but may need adjustment to match HikariCP's expected format:
```hocon
database {
dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
dataSource {
serverName = "localhost"
portNumber = 5432
databaseName = "summercms"
user = "summercms"
password = "summercms"

Update HealthRoutes to include database connectivity check.

- Keep existing GET /health -> Response.text("ok") (always 200)
- Add GET /ready endpoint:
- Requires DataSource from ZLayer
- Attempts: ZIO.attempt(ds.getConnection.close())
- Success: Response.text("ready") with 200
- Failure: Response.status(Status.ServiceUnavailable) with 503

ZIO.attempt {
val conn = ds.getConnection
conn.close()
}.as(Response.text("ready"))
.catchAll(_ => ZIO.succeed(Response.status(Status.ServiceUnavailable)))
}

Update Main.scala to:
- Provide dataSourceLayer to the server
- On startup, run Migrator.migrate and log result
- Startup sequence: migrate -> start server
Note: The /ready endpoint will return 503 if no database is running, which is correct behavior.

3. Check database: `psql -d summercms -c "\\dt"` shows summer_users table
4. Check migrations table: `psql -d summercms -c "SELECT * FROM summer_migrations"`

email: String,
passwordHash: String,

case class Conflict(entity: String, message: String) extends RepositoryError
case class ValidationError(errors: List[String]) extends RepositoryError
case class DatabaseError(message: String, cause: Option[Throwable] = None) extends RepositoryError
```
3. src/repository/UserRepository.scala:
- Trait UserRepository with methods:
- def findById(id: Long): IO[RepositoryError, Option[User]]
- def findByEmail(email: String): IO[RepositoryError, Option[User]]
- def create(email: String, passwordHash: String): IO[RepositoryError, User]
- def update(user: User): IO[RepositoryError, User]
- def delete(id: Long): IO[RepositoryError, Unit]
- Object UserRepository with:
- val live: ZLayer[Quill.Postgres[SnakeCase], Nothing, UserRepository]
- Class UserRepositoryLive(quill: Quill.Postgres[SnakeCase]) extends UserRepository:
- import quill.*
- inline def users = quote(querySchema[User]("summer_users"))
- Implement all methods using Quill queries
- Use refineOrDie to convert SQLException to RepositoryError.DatabaseError
- Handle unique constraint violations as Conflict errors
Pattern for error handling:
```scala
def create(email: String, passwordHash: String): IO[RepositoryError, User] =
val now = Instant.now()
val user = User(0, email, passwordHash, now, now)
run(users.insertValue(lift(user)).returningGenerated(_.id))
.map(id => user.copy(id = id))
.refineOrDie {
case e: java.sql.SQLException if e.getSQLState == "23505" =>
RepositoryError.Conflict("User", s"Email $email already exists")
case e: java.sql.SQLException =>
RepositoryError.DatabaseError(e.getMessage, Some(e))

<name>Task 2: Create Pulumi infrastructure with Besom</name>
<files>
infra/project.scala
infra/Main.scala
</files>
<action>
Create Pulumi infrastructure using Besom (Scala Pulumi SDK).
IMPORTANT: Besom does NOT support Mill. Use Scala CLI for the infra/ directory.
1. infra/project.scala (Scala CLI project config):
```scala
//> using scala 3.3.4
//> using dep org.virtuslab::besom-core:0.4.0
//> using dep org.virtuslab::besom-aws:6.56.0
```
Note: Use Besom 0.4.0 (latest stable on Maven Central, not 0.5.0 from research).
2. infra/Main.scala:
```scala
import besom.*
import besom.api.aws
@main def main = Pulumi.run {
// Configuration
val config = besom.Config()
val environment = config.get("environment").getOrElse("dev")
// S3 bucket for assets (optional CDN origin)
val assetsBucket = aws.s3.Bucket(
s"summercms-assets-$environment",
aws.s3.BucketArgs()
)
// RDS PostgreSQL instance
val db = aws.rds.Instance(
s"summercms-db-$environment",
aws.rds.InstanceArgs(
engine = "postgres",
engineVersion = "16.4",
instanceClass = "db.t3.micro",
allocatedStorage = 20,
dbName = "summercms",
username = "summercms",
password = config.requireSecret("dbPassword"),
skipFinalSnapshot = environment == "dev",
publiclyAccessible = environment == "dev"
)
)
// ECS for container deployment (placeholder for now)
// Full ECS setup deferred to when we need actual deployment
Stack.exports(
assetsBucketName = assetsBucket.bucket,
dbEndpoint = db.endpoint,
dbPort = db.port
)
}
```
This provides:
- Multi-environment support via Pulumi config
- S3 bucket for future asset storage
- RDS PostgreSQL for database
- Secrets management for DB password
- Outputs for connecting the application
Note: Full ECS/container deployment is deferred. This establishes the pattern.

<action>
Create multi-stage Dockerfile for building and running SummerCMS.
Dockerfile:

# Stage 1: Build
FROM eclipse-temurin:21-jdk AS builder
# Install Mill
RUN curl -L https://github.com/com-lihaoyi/mill/releases/download/0.12.3/0.12.3 > /usr/local/bin/mill && \

EXPOSE 8080

Features:
- Multi-stage build (builder has JDK+Mill, runtime has only JRE)
- Uses Eclipse Temurin JDK 21 (LTS)
- Health check using /health endpoint
- Minimal runtime image size
- Environment variables configure the app (via application.conf ${?VAR} substitution)
Usage:
