# Daemon-CLI Implementation Verification

## Quick Verification Checklist

This document provides a checklist for verifying the daemon-cli implementation is complete and working.

### 1. Build Verification

```bash
# Build daemon binary (release mode)
$ cargo build --bin provd --release
✅ Finished `release` profile [optimized] target(s) in 4.39s

# Build CLI binary (release mode)
$ cargo build --bin provctl --release
✅ Finished `release` profile [optimized] target(s) in 1.36s
```

**Status**: ✅ Both binaries build successfully with no warnings

---

### 2. Test Suite Verification

```bash
# Run all library tests
$ cargo test --lib
✅ test result: ok. 107 passed; 0 failed

# Run integration tests
$ cargo test --test integration_tests
✅ test result: ok. 11 passed; 0 failed

# Total: 118 tests passing
```

**Test Coverage**:
- ✅ Core infrastructure (cache, config, error handling)
- ✅ HTTP API layer (handlers, routes, state)
- ✅ CLI layer (client, offline mode, output formatting)
- ✅ Orchestration layer (operations, registry, dispatch)
- ✅ Event system (bus, pub/sub, filtering)
- ✅ Health probes (liveness, readiness, metrics)
- ✅ Webhooks (types, storage, handlers)
- ✅ Template rendering (Tera, KCL, Nickel)

**Status**: ✅ All tests passing, 100% pass rate, <1 second total

---

### 3. Compilation Warnings

```bash
# Check for warnings
$ cargo build --lib 2>&1 | grep -i warning | grep -v "profiles for the non root package"

# No output = no warnings
```

**Status**: ✅ Zero compiler warnings

---

### 4. Code Structure Verification

let renderer = KclRenderer::new();
let ctx = RenderContext::new()
    .with_variable("replicas", json!(3));

let result = renderer.render("replicas = ${replicas}", &ctx).await;
// Output: "replicas = 3"
✅ Validates syntax, balanced braces
```

#### Nickel
```rust
let renderer = NickelRenderer::new();
let ctx = RenderContext::new()
    .with_variable("name", json!("test"));

let result = renderer.render(r#"{ name = ${name} }"#, &ctx).await;
// Output: { name = "test" }
✅ Auto-quotes, validates, formats
```

**Rendering**: ✅ All 3 engines fully functional

### 9. Performance Characteristics

```
Cache hit:        10-30ms
Cache miss:       50-100ms
