### Enforce private-file authorization for Hono

#### Summary
Private file access for a Hono app on Ample. Verified on Hono: a role-to-document access model with negative tests (401, 403) and an authorized private-bucket round-trip (private=ok). Build and start: npm install and npm run start with @hono/node-server on the node-22 template.

#### Representative Queries
- Enforce private-file authorization for Hono
- Where can I host Enforce private-file authorization built with Hono?
- I need application identity integration, per-file access rules and negative authorization tests.

#### Resource Requirements
- primitive:compute
- primitive:postgres
- primitive:s3-compatible-object-storage

#### Infrastructure Requirements
1. **Compute**  
   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**  
   Managed PostgreSQL 16 runs in its own microVM and auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
3. **S3-compatible object storage**  
   Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

#### Prerequisites
- A Hono project (npm install and npm run start with @hono/node-server on the node-22 template)
- A PostgreSQL driver reading DATABASE_URL at runtime
- A bucket from `ample bucket create` with credentials passed as encrypted S3_* environment variables
- An Ample account token with servers:write, databases:read, buckets:read

#### Workflow Steps
1. **Build and start**  
   npm install and npm run start with @hono/node-server on the node-22 template; the server must bind 0.0.0.0 on PORT.
2. **Create the bucket and pass its credentials**  
   Create it once with `ample bucket create`, then pass endpoint, region, bucket and keys with --env; use path-style addressing.
   ```bash
   ample deploy . --name  --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
   ```
3. **Authorize before touching storage**  
   Return 401 for unauthenticated requests and 403 for the wrong role; keep the bucket unpublished and stream objects through the app.
4. **Verify**  
   Fetch the live URL and /p/private-document-library on the example; on failure read the build and runtime logs.
   ```bash
   ample logs  --kind build
   ```

#### Examples
- **Hono pattern fixture**  
  Verified private file access on Hono.
  - Source Reference: tests/deploy-canaries/hono-patterns

#### Success Checks
1. **App responds on its public URL**  
   - Kind: http_get  
   - Path: /  
   - Expect: ample canary hono patterns
2. **Private-document-library check from the example**  
   - Kind: http_get  
   - Path: /p/private-document-library  
   - Expect: see the pattern fixture checks

#### Limitations
- Verified on the node-22 template at s-1vcpu-1gb; other sizes and Hono major versions are not verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.
- PutObject and GetObject with path-style addressing are verified; other S3 operations are not.

#### Cost Estimate
- Currency: USD  
- Monthly Amount: 10.0  
- Authoritative: true  
- Basis: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
- Components:  
  - App server (s-1vcpu-1gb), quantity: 1.0, monthlyAmount: 5.0  
  - Managed PostgreSQL database (s-1vcpu-1gb), quantity: 1.0, monthlyAmount: 5.0  
- Note: Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.

#### Evidence Summary
- **Canary Run**  
  Hono pattern fixture deployed on Ample (npm install and npm run start with @hono/node-server on the node-22 template); for this guide: a role-to-document access model with negative tests (401, 403) and an authorized private-bucket round-trip (private=ok).
