# GRASP Audit

A reusable audit and compliance testing tool for GRASP protocol implementations.

## Features

- ✅ **Isolated Testing**: Tests run in parallel with unique audit IDs
- ✅ **Production Audit**: Test live services with minimal impact
- ✅ **Clean Audit Events**: Special tags for easy cleanup (no deletion trails)
- ✅ **Spec-Mirrored Tests**: Test structure matches GRASP protocol exactly
- ✅ **Reusable**: Can test any GRASP implementation (Rust, Go, Python, etc.)

## Quick Start

### As a Library

```rust
use grasp_audit::*;

#[tokio::main]
async fn main() -> Result<()> {
    // Create audit client for CI testing
    let config = AuditConfig::ci();
    let client = AuditClient::new("ws://localhost:7000", config).await?;
    
    // Run NIP-01 smoke tests
    let results = specs::Nip01SmokeTests::run_all(&client).await;
    results.print_report();
    
    if !results.all_passed() {
        std::process::exit(1);
    }
    
    Ok(())
}
```

### As a CLI Tool

```bash
# Install
cargo install --path .

# Run smoke tests against local relay
grasp-audit audit --relay ws://localhost:7000 --mode ci --spec nip01-smoke

# Audit production server (read-only)
grasp-audit audit --relay wss://relay.example.com --mode production --spec all
```

## Test Specifications

### NIP-01 Smoke Tests (6 tests)

Basic Nostr relay functionality:

1. `websocket_connection` - Can connect to /
2. `send_receive_event` - Can send EVENT, get OK
3. `create_subscription` - Can subscribe with REQ
4. `close_subscription` - Can close subscriptions
5. `reject_invalid_signature` - Rejects bad signatures
6. `reject_invalid_event_id` - Rejects wrong IDs

**Why only smoke tests?** rust-nostr already has 1000+ tests for NIP-01 compliance. We focus on GRASP-specific behavior.

### GRASP-01 Tests (Coming Soon)

- Repository announcement acceptance
- State event handling
- Policy enforcement
- And more...

## Audit Event Strategy

All audit events include special tags:

```json
{
  "tags": [
    ["grasp-audit", "true"],
    ["audit-run-id", "ci-a1b2c3d4-e5f6-7890-abcd-ef1234567890"],
    ["audit-cleanup", "2025-11-03T12:00:00Z"]
  ]
}
```

This allows:
- **Isolation**: Each test run has unique ID
- **Cleanup**: Events marked for cleanup after timestamp
- **No deletion trails**: Direct database cleanup (no NIP-09 deletion events)

## Modes

### CI Mode (Default)

- Tests are isolated by unique run ID
- Tests only see their own events
- Full read/write access
- Cleanup after 1 hour

```rust
let config = AuditConfig::ci();
```

### Production Mode

- Tests see all events (including real ones)
- Read-only by default (minimal impact)
- Cleanup after 5 minutes

```rust
let config = AuditConfig::production();
```

## Examples

See `examples/` directory:

```bash
# Simple audit example
cargo run --example simple_audit
```

## Testing

### Unit Tests

```bash
# Enter dev environment (NixOS)
nix develop

# Run unit tests (no relay required)
cargo test
```

### Integration Tests Against ngit-relay

Test against the reference GRASP implementation to ensure compatibility.

**Automated Script (Recommended):**

```bash
# Handles setup, testing, and cleanup automatically
./test-ngit-relay.sh
```

See `test-ngit-relay.sh` for full setup/cleanup details.

**Manual One-Liner:**

```bash
# Start relay, then run: RELAY_URL="ws://localhost:$PORT" cargo test --lib -- --ignored --nocapture
```

**Note:** ngit-relay only accepts Git-related events (NIP-34). Some NIP-01 smoke tests will fail (expected). Validation tests should pass.

### Testing Against General-Purpose Relays

For full NIP-01 smoke test coverage (all 6 tests passing), test against a general-purpose relay:

```bash
# Start nostr-rs-relay (accepts all event kinds)
docker run --rm -d --name nostr-test-relay -p 7000:8080 scsibug/nostr-rs-relay

# Run tests (all should pass)
cargo test --lib -- --ignored --nocapture

# Cleanup
docker stop nostr-test-relay
```

Expected: 6/6 tests passed (100%)
