## The short version

A client portal blueprint for video production built with Django on Ample. Domain schema: 
- **customer_workspaces** (client_name, project_count): client organizations;  
- **projects** (workspace_id, title, stage, delivery_due_at): productions in flight;  
- **cuts** (project_id, version, object_key, review_status, reviewed_at): versioned cuts for review;  
- **customer_assets** (workspace_id, project_id, object_key, visibility): final deliverables and raw footage access;  
- **document_access** (document_id, principal_reference, role, granted_at): who may read which document.  
Public information: showreel and services, production process, contact. Kept out of scope until handling is reviewed: unreleased footage, talent releases and contracts, client brand material. Footage is large and confidential; the storage checks here use small objects, so verify large-file behavior separately. Technical basis verified on Django: 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 Django project (pip install into .ample/python from requirements.txt, then waitress serving project.wsgi from run.py reading PORT on the python-3.12 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 video production data classes may be handled at all; this blueprint models public information only

## How to do it

1. **Model the video production domain**  
   Create the tables customer_workspaces, projects, cuts, customer_assets, document_access. Client organizations lives in customer_workspaces; keep the sensitive classes (unreleased footage, talent releases and contracts, client brand material) 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 --start "python3 run.py" --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 video production workflow.
   
   ```  
   ample logs <deployment_id> --kind build
   ```

## Tested examples

- **Django pattern fixture** (`tests/deploy-canaries/django-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 django patterns)
- private-document-library self-test from the example (`/p/private-document-library` on the live URL, expect 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

The blueprint's Video production schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-19T03:31:44Z)
