## The short version

A client portal blueprint for creator businesses built with Next.js on Ample. Domain schema: 
- **customer_workspaces** (name, membership_tier, joined_at): member accounts or communities;  
- **content_items** (title, tier_required, object_key, published_at, version): versioned content releases;  
- **customer_assets** (workspace_id, title, object_key, visibility): downloads granted to a member;  
- **releases** (content_item_id, version, notes): release notes per version;  
- **document_access** (document_id, principal_reference, role, granted_at): who may read which document.  
Public information: free content and previews, membership tiers, creator profile.  
Kept out of scope until handling is reviewed: member identity and payment status, private community posts. Member payment status comes from your payment provider; it is not modeled here and no PCI claim is made. Technical basis verified on Next.js: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok).

## What it needs

- [Compute](/content/discover/primitive/compute/index.html): verified (Apps run in isolated x86_64 Firecracker microVMs; sizes are the priced VM sizes.)  
- [Postgres](/content/discover/primitive/postgres/index.html): verified (Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.)  
- [S3-compatible object storage](/content/discover/primitive/s3-compatible-object-storage/index.html): verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)

## Before you start

- A Next.js project (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template)  
- A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)  
- Bucket credentials from `ample bucket create` passed as encrypted S3_* environment variables  
- A review of which creator businesses data classes may be handled at all; this blueprint models public information only

## How to do it

1. **Model the creator businesses domain**  
   Create the tables customer_workspaces, content_items, customer_assets, releases, document_access. Member accounts or communities live in customer_workspaces; keep the sensitive classes (member identity and payment status, private community posts) out of this schema.

2. **Workflow step 1**  
   Model client entities and engagement periods; every document belongs to one engagement

3. **Workflow step 2**  
   Authorize by client entity and role before any storage access (401 without identity, 403 for the wrong client)

4. **Workflow step 3**  
   Store documents in the private bucket and stream them through the app

5. **Workflow step 4**  
   Deploy and verify the negative authorization tests and an authorized download

6. **Deploy**  
   Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
   
   ```  
   ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...  
   ```

7. **Verify**  
   Run the pattern self-test(s) from the example (/p/private-document-library) and your own acceptance checks for the creator businesses workflow.
   
   ```  
   ample logs <deployment_id> --kind build  
   ```

## Tested examples

- **Next.js pattern fixture** (`tests/deploy-canaries/next-js-patterns`): Verified private document library basis for this blueprint.

## How to know it worked

- app responds on its public URL (`/` on the live URL, expect ample canary next js patterns)  
- private-document-library self-test from the example (`/p/private-document-library` on the live URL, expect to see the pattern fixture checks)

## Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision ca0b484a7a9957c573a88d3a32dc603c3c10135a).

- app server x1 `s-1vcpu-1gb`: 5.00 USD  
- managed PostgreSQL database x1 `s-1vcpu-1gb`: 5.00 USD

Upper-bound monthly price of the tested sizes. Buckets are allocation-priced per quota and not included.

## Verification evidence

- canary_run on 2026-09-21T02:34:39Z at revision `1d28ae0 (CLI 0.1.21)`: Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); the private document library checks passed: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). The blueprint's Creator businesses schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
