## Features Implemented

### 1. Audit Event Tagging System ✅

**Purpose:** Identify and clean up test events without deletion trails

**Implementation:**
- Automatic tag injection on all events
- Three tags: `grasp-audit`, `audit-run-id`, `audit-cleanup`
- Timestamp-based expiration
- No NIP-09 deletion events needed

**Example Event:**
```json
{
  "id": "abc123...",
  "kind": 1,
  "content": "Test event",
  "tags": [
    ["grasp-audit", "true"],
    ["audit-run-id", "ci-a1b2c3d4-e5f6-7890-abcd-ef1234567890"],
    ["audit-cleanup", "2025-11-04T13:00:00Z"]
  ]
}
```

### 2. Test Isolation ✅

**Purpose:** Run tests in parallel without interference

**CI Mode:**
- Unique UUID per run
- Tests only see their own events
- Full read/write access
- Cleanup after 1 hour
- Perfect for CI/CD pipelines

**Production Mode:**
- Timestamp-based run ID
- Tests see all events (real + audit)
- Read-only by default
- Cleanup after 5 minutes
- Minimal impact on live services

### 3. NIP-01 Smoke Tests ✅

**Purpose:** Verify basic Nostr relay functionality

**Tests Implemented:**

1. **websocket_connection** (NIP-01:basic)
   - Verifies WebSocket connection to /
   - Checks relay is responsive

2. **send_receive_event** (NIP-01:event-message)
   - Sends EVENT message
   - Receives OK response
   - Queries event back

3. **create_subscription** (NIP-01:req-message)
   - Creates REQ subscription
   - Receives EOSE
   - Gets subscribed events

4. **close_subscription** (NIP-01:close-message)
   - Tests subscription management
   - Verifies CLOSE handling

5. **reject_invalid_signature** (NIP-01:validation)
   - Sends event with wrong signature
   - Verifies relay rejects it

6. **reject_invalid_event_id** (NIP-01:validation)
   - Sends event with wrong ID
   - Verifies relay rejects it

**Why only 6 tests?** rust-nostr has 1000+ tests for NIP-01. We focus on smoke tests to verify the relay is working at all.

### 4. Test Result Framework ✅

**Purpose:** Collect and report test results

**Features:**
- Detailed test metadata (name, spec ref, requirement)
- Pass/fail status with error messages
- Timing information for each test
- Pretty-printed reports
- Summary statistics
- Exit code support for CI/CD

**Example Output:**
```
NIP-01 Smoke Tests
══════════════════════════════════════════════════════════

✓ websocket_connection (NIP-01:basic)
  Requirement: Can establish WebSocket connection to /
  Duration: 523ms

✓ send_receive_event (NIP-01:event-message)
  Requirement: Can send EVENT and receive OK response
  Duration: 1.2s

Results: 6/6 passed (100.0%)
```

### 5. CLI Tool ✅

**Purpose:** Run audits from command line

**Commands:**
- `audit` - Run compliance tests
- `cleanup` - Clean old audit events (planned)
- `list` - List audit events (planned)

**Usage:**
```bash
# CI mode
grasp-audit audit --relay ws://localhost:7000 --mode ci --spec nip01-smoke

# Production mode
grasp-audit audit --relay wss://relay.example.com --mode production --spec all
```

**Features:**
- Pretty output with emojis
- Multiple spec support
- Mode selection (ci/production)
- Proper exit codes
- Logging support

### 6. Library API ✅

**Purpose:** Use as a dependency in other projects

**Public API:**
```rust
pub use audit::{AuditConfig, AuditMode};
pub use client::AuditClient;
pub use result::{AuditResult, TestResult};
pub use specs::Nip01SmokeTests;
```

**Example:**
```rust
use grasp_audit::*;

let config = AuditConfig::ci();
let client = AuditClient::new("ws://localhost:7000", config).await?;
let results = specs::Nip01SmokeTests::run_all(&client).await;
results.print_report();
```

```

---

## Testing Status

### Unit Tests: ✅ Ready (Pending Build)

```bash
cd grasp-audit
nix-shell
cargo test --lib
```

**Expected Results:**
- 13 unit tests
- All should pass
- No relay needed

### Integration Tests: ✅ Ready (Pending Relay)

```bash
# Start relay first
cargo test --ignored
```

**Expected Results:**
- 6 smoke tests
- All should pass against working relay
- Requires relay at ws://localhost:7000

### CLI Tests: ✅ Ready (Pending Build)

```bash
cargo build --release
./target/release/grasp-audit audit \
  --relay ws://localhost:7000 \
  --mode ci \
  --spec nip01-smoke
```

**Expected Results:**
- Pretty output
- All tests pass
- Exit code 0

---

## Build Environment

### Issue

NixOS environment missing C compiler for build scripts.

### Solution Provided

Created `grasp-audit/shell.nix`:

```nix
{ pkgs ? import <nixpkgs> {} }:

pkgs.mkShell {
  buildInputs = with pkgs; [
    rustc cargo rustfmt clippy
    gcc pkg-config openssl git
  ];
}
```

### Usage

```bash
cd grasp-audit
nix-shell
cargo build
```

---

## Architecture Highlights

### Clean Separation of Concerns

```
Audit Config (audit.rs)
    ↓
AuditClient (client.rs)
    ↓
Test Specs (specs/*.rs)
    ↓
Test Results (result.rs)
```

### Extensibility

New specs can be added easily:

```rust
// src/specs/grasp_01_relay.rs (future)
pub struct Grasp01RelayTests;

impl Grasp01RelayTests {
    pub async fn run_all(client: &AuditClient) -> AuditResult {
        // 12+ tests for GRASP-01 compliance
    }
}
```

### Reusability

Can test ANY GRASP implementation:
- Rust (ngit-grasp)
- Go (ngit-relay)
- Python
- JavaScript
- Any language with a Nostr relay

---

## Next Steps

### Immediate (Unblock)

1. **Configure build environment:**
   ```bash
   cd grasp-audit
   nix-shell
   ```

2. **Build project:**
   ```bash
   cargo build
   ```

3. **Run unit tests:**
   ```bash
   cargo test --lib
   ```

4. **Verify all pass**

### Short Term (Complete Smoke Tests)

1. **Set up test relay:**
   - Use nostr-relay-builder example
   - Or any Nostr relay at ws://localhost:7000

2. **Run integration tests:**
   ```bash
   cargo test --ignored
   ```

3. **Test CLI:**
   ```bash
   cargo run --example simple_audit
   ```

4. **Document results**

### Medium Term (GRASP-01)

1. **Implement `specs/grasp_01_relay.rs`:**
   - Repository announcement tests
   - State event tests
   - Policy enforcement tests
   - Related event tests

2. **Test against ngit-grasp:**
   - Run audit during development
   - Fix issues found
   - Iterate until all pass

3. **Implement cleanup utilities:**
   - CLI cleanup command
   - Database cleanup script
   - Scheduled cleanup example

### Long Term (Full Compliance)

1. **GRASP-02 tests** (Proactive Sync)
2. **GRASP-05 tests** (Archive)
3. **Performance benchmarks**
4. **CI/CD templates**
5. **Publish to crates.io**

## Key Design Patterns

### 1. Builder Pattern
```rust
let event = client
    .event_builder(Kind::TextNote, "content")
    .tag(Tag::custom(...))
    .build(keys)
    .await?;
```

### 2. Async/Await
```rust
let results = futures::join_all(tests).await;
```

### 3. Result Types
```rust
pub type Result<T> = std::result::Result<T, anyhow::Error>;
```

### 4. Test Isolation
```rust
if config.mode == AuditMode::CI {
    filter = filter.custom_tag(..., [&run_id]);
}
```

      - name: Start Relay
        run: docker run -d -p 7000:7000 nostr-relay
      - name: Run Audit
        run: |
          cd grasp-audit

          cargo run -- audit --relay ws://localhost:7000
```

### For Production Monitoring

```bash
#!/bin/bash
# Daily audit of production relay

./grasp-audit audit \
  --relay wss://your-relay.com \
  --mode production \
  --spec all

if [ $? -ne 0 ]; then
  # Alert on failure
  curl -X POST https://hooks.slack.com/... \
    -d '{"text":"Production audit failed!"}'
