## Host Member Portal with SvelteKit: Tenant-Scoped Workspaces

### Summary
Deploy a member portal built with SvelteKit on Ample using the multi-tenant relational data pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL. Verified on SvelteKit: a tenant column on every row and query, with a cross-tenant read returning nothing (tenant_isolation=ok). Not separately tested: your tenant model, membership, and per-tenant authorization; treat the member portal-specific behavior as your application code.

### Representative Queries
- Host member portal with SvelteKit: tenant-scoped workspaces
- Where can I host Member portal built with SvelteKit?
- I need an explicit tenant model and application-enforced tenant isolation tests.

### Resource Requirements
- **Compute**
- **Postgres**

### Infrastructure Requirements
1. **Compute**
   - **Status**: verified  
   - **Summary**: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.

2. **Postgres**
   - **Status**: verified  
   - **Summary**: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.

### Prerequisites
- A SvelteKit project that builds and starts with the documented commands (vite build with @sveltejs/adapter-node then node build on the node-22 template)
- A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env)
- An Ample account token with servers:write, databases:read

### Workflow Steps
1. **Build and start** 
   - vite build with @sveltejs/adapter-node then node build on the node-22 template. The server must bind 0.0.0.0 on PORT.

2. **Implement the pattern on PostgreSQL** 
   - The fixture's module implements multi-tenant relational data: a tenant column on every row and query, with a cross-tenant read returning nothing (tenant_isolation=ok). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

3. **Deploy** 
   - Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked). Re-running with no change is a no-op.  
   - **Command**: ample deploy . --name --public

4. **Verify** 
   - Fetch the live URL and the pattern self-test route(s) (/p/multi-tenant-relational-data) from the example; then run your own checks. On failure read `ample logs --kind build` then `--kind runtime`.  
   - **Command**: ample logs --kind build

### Examples
- **SvelteKit pattern fixture**  
  Multi-pattern SvelteKit app whose multi-tenant relational data module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

- **Prepare a side-effect-free deployment plan for an authorized project**  
- **Read the existing agent authentication setup**  
- **Browse Member portal**  
- **Browse SvelteKit**  
- **Browse Multi-tenant relational data**  
- **Browse Deploy web app**

### Limitations
- Verified on the node-22 template at s-1vcpu-1gb with the example fixture; other sizes, templates and SvelteKit major versions are not verified.  
- The member portal itself (your tenant model, membership, and per-tenant authorization) is application code and was not separately tested; the pattern checks are what was verified.

### Cost Estimate
- **Monthly Amount**: $10.0 USD  
- **Components**:  
  - app server: size s-1vcpu-1gb, quantity 1.0, monthlyAmount $5.0  
  - managed PostgreSQL database: size s-1vcpu-1gb, quantity 1.0, monthlyAmount $5.0  
  **Note**: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

### Evidence Summary
- **Canary Run**  
  Summary: SvelteKit pattern fixture deployed on Ample (vite build with @sveltejs/adapter-node then node build on the node-22 template); checks passed for multi-tenant-relational-data and configuration-secrets.
