stores

Defines user-managed S3 buckets for application data. Unlike other composites, stores has no app code — it creates only infrastructure.

Configuration

{
  "stores": [
    {"name": "images", "versioning": false, "ttl_days": 0},
    {"name": "notes", "versioning": true, "ttl_days": 30}
  ]
}

Field	Description
`name`	Bucket identifier. Used in resource naming and as the `{PREFIX}_BUCKET` env var (e.g., `IMAGES_BUCKET`).
`versioning`	Enable S3 versioning on this bucket.
`ttl_days`	Lifecycle rule: automatically delete objects after this many days. `0` means no expiration.

An empty array ("stores": []) means no store buckets are created.

Each store bucket is automatically exposed as an environment variable to Lambda services:

{NAME}_BUCKET=images-dev-ral-us-east-1-059279877465

The IAM policy generated from deployiam.json grants services read/write access to all store buckets.
