 ## Features
 
 - **Auto-provisioning hook** — Wraps `create*` mutations on tables tagged with `@storageBuckets` to automatically provision S3 buckets after row creation
+- **CORS update hook** — Wraps `update*` mutations to detect `allowed_origins` changes and re-apply CORS rules to the S3 bucket
+- **3-tier CORS resolution** — Bucket-level `allowed_origins` → storage module-level `allowed_origins` → plugin config `allowedOrigins`
+- **Wildcard CORS** — Set `allowed_origins = ['*']` on a bucket for fully open CDN/public deployments
 - **Explicit `provisionBucket` mutation** — GraphQL mutation for manual/retry provisioning of any bucket
-- **Per-database overrides** — Reads `endpoint`, `provider`, and `public_url_prefix` from the `storage_module` table for multi-tenant setups

 - **Lazy S3 config** — Connection config can be a function (evaluated once, cached) to avoid eager env-var reads at import time
-- **Graceful error handling** — Provisioning failures are logged but never fail the mutation (admin can retry via `provisionBucket`)
