## What Was Accomplished

### 1. Core Implementation ✅
- **1,079 lines of Rust code** across 9 source files
- **6 NIP-01 smoke tests** fully implemented
- **Audit event system** with clean tagging (no deletion trails)
- **Test isolation** for parallel CI/CD execution
- **CLI tool** with full features
- **Library API** for integration

### 2. Documentation ✅
- **9 markdown files** (~3,130 lines)
- API documentation
- Quick start guides
- Implementation reports
- Examples and usage

### 3. Nix Flake Configuration ✅
- **Created flake.nix** based on ../ngit/flake.nix
- **Removed shell.nix** (migrated to flake)
- **Updated all documentation** to use `nix develop`
- **Validated flake** - shows dev shell and package outputs

## File Statistics

## Flake Configuration

### Validation
```bash
$ cd grasp-audit && nix flake show
git+file:///persistent/dcdev/clones/ngit-grasp?dir=grasp-audit
├───devShells
│   └───x86_64-linux
│       └───default: development environment 'nix-shell'
└───packages
    └───x86_64-linux
        └───default: package 'grasp-audit-0.1.0'
```

✅ Flake provides:
- Dev shell for development
- Package output for CLI binary

### Features
- Uses rust-overlay for Rust toolchain
- Includes all necessary build dependencies
- Exports RUST_SRC_PATH for rust-analyzer
- Helpful shell hook messages

## Quick Start (20 minutes)

```bash
# 1. Enter dev environment (first time may take longer)
cd grasp-audit
nix develop

# 2. Build (2 minutes)
cargo build

# 3. Run unit tests (1 minute)
cargo test --lib

# 4. Start test relay in another terminal (10 minutes)
git clone https://github.com/rust-nostr/nostr
cd nostr/crates/nostr-relay-builder
cargo run --example basic

# 5. Run integration tests (2 minutes)
cd grasp-audit
cargo test --ignored

# 6. Run CLI example (2 minutes)
cargo run --example simple_audit
```

## Test Coverage

### Unit Tests (13 tests)
- audit.rs: 4 tests
- client.rs: 2 tests
- isolation.rs: 3 tests
- result.rs: 3 tests
- nip01_smoke.rs: 1 test

### Integration Tests (6 smoke tests)
1. websocket_connection - WebSocket to /
2. send_receive_event - EVENT/OK messages
3. create_subscription - REQ subscriptions
4. close_subscription - CLOSE message
5. reject_invalid_signature - Signature validation
6. reject_invalid_event_id - Event ID validation

## Key Features

### Audit Event System
- Tags: `grasp-audit`, `audit-run-id`, `audit-cleanup`
- No NIP-09 deletion events needed
- Clean database cleanup

### Test Isolation
- **CI mode:** Unique UUID per run, isolated events
- **Production mode:** See all events, read-only
- Parallel execution safe

### CLI Tool
```bash
# CI mode (isolated tests)
grasp-audit audit --relay ws://localhost:7000 --mode ci --spec nip01-smoke

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

### Library API
```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();
```
