```bash
# Show 6 service plugins
clnrm plugins

# ✅ Generic containers, databases, network tools
```

## 🚀 **Version 1.0.0 Features (Current)**

### **✅ No-Prefix Tera Templating (Implemented)**

Create clean, readable templates with no complex namespaces:

```toml
[meta]
name = "{{ svc }}_otel_proof"
version = "1.0.0"
description = "Telemetry-only validation"

[vars]                # authoring-only; runtime ignores this table
svc = "{{ svc }}"
env = "{{ env }}"
endpoint = "{{ endpoint }}"
exporter = "{{ exporter }}"
freeze_clock = "{{ freeze_clock }}"
image = "{{ image }}"

[otel]
exporter = "{{ exporter }}"
endpoint = "{{ endpoint }}"
protocol = "http/protobuf"
sample_ratio = 1.0
resources = { "service.name" = "{{ svc }}", "env" = "{{ env }}" }

[service.clnrm]
plugin = "generic_container"
image = "{{ image }}"
args = ["self-test", "--otel-exporter", "{{ exporter }}", "--otel-endpoint", "{{ endpoint }}"]
env = { "OTEL_TRACES_EXPORTER" = "{{ exporter }}", "OTEL_EXPORTER_OTLP_ENDPOINT" = "{{ endpoint }}" }
wait_for_span = "clnrm.run"

[[scenario]]
name = "otel_only_proof"
service = "clnrm"
run = "clnrm run --otel-exporter {{ exporter }} --otel-endpoint {{ endpoint }}"
artifacts.collect = ["spans:default"]

[[expect.span]]
name = "clnrm.run"
kind = "internal"
attrs.all = { "result" = "pass" }

[[expect.span]]
name = "clnrm.step:hello_world"
parent = "clnrm.run"
kind = "internal"
events.any = ["container.start", "container.exec", "container.stop"]

[expect.graph]
must_include = [["clnrm.run", "clnrm.step:hello_world"]]
acyclic = true

[expect.status]
all = "OK"

[expect.hermeticity]
no_external_services = true
resource_attrs.must_match = { "service.name" = "{{ svc }}", "env" = "{{ env }}" }

[determinism]
seed = 42
freeze_clock = "{{ freeze_clock }}"

[report]
json = "report.json"
digest = "trace.sha256"
```

### **Rust-Based Variable Resolution**

Variables are resolved in Rust with clear precedence:
- **Template variables** (highest priority)
- **Environment variables** (e.g., `$SERVICE_NAME`, `$OTEL_ENDPOINT`)
- **Defaults** (lowest priority)

**Available Variables:**
- `svc` - Service name (default: "clnrm")
- `env` - Environment (default: "ci")
- `endpoint` - OTEL endpoint (default: "http://localhost:4318")
- `exporter` - OTEL exporter (default: "otlp")
- `image` - Container image (default: "registry/clnrm:1.0.0")
- `freeze_clock` - Deterministic time (default: "2025-01-01T00:00:00Z")
- `token` - OTEL auth token (default: "")

### **Template Generation**

```bash
# Generate OTEL validation template
clnrm template otel > my-test.clnrm.toml

# The generated template uses no-prefix variables
# Variables are resolved in Rust: template vars → ENV → defaults
```

## 🎯 Legacy v0.6.0 Features

### **Property-Based Testing with Fake Data**

Generate test scenarios with fake data generators:

```toml
# tests/load-test.clnrm.toml.tera
{% for i in range(end=1000) %}
[[steps]]
name = "load_test_{{ i }}"
command = ["curl", "http://api:8080/users",
           "-d", '{"name":"{{ fake_name() }}","email":"{{ fake_email() }}"}']
expected_output_regex = "success"
{% endfor %}
```

**Key Features:**
- **50+ fake data generators** - UUIDs, names, emails, timestamps, IPs, etc.
- **Deterministic seeding** - Reproducible tests with `fake_uuid_seeded(seed=42)`
- **Matrix testing** - Generate all combinations of parameters
- **Property-based testing** - Validate properties across generated data

**Example: 1000 unique API tests generated from 10 lines of template code!**

### **Telemetry-Only Validation (OTEL)**

Prove system correctness using OpenTelemetry spans exclusively:

```toml
# tests/otel-validation.clnrm.toml
[services.otel_collector]
plugin = "otel_collector"
image = "otel/opentelemetry-collector:latest"

[services.app_under_test]
plugin = "generic_container"
image = "myapp:latest"
env.OTEL_EXPORTER_OTLP_ENDPOINT = "http://otel_collector:4318"

[[scenario]]
name = "otel_self_validation"
service = "app_under_test"
run = "myapp --otel-endpoint http://otel_collector:4318"

# Validate spans prove correct behavior
[[expect.span]]
name = "myapp.request"
kind = "server"
duration_ms = { min = 10, max = 5000 }

[[expect.span]]
name = "myapp.db_query"
parent = "myapp.request"
kind = "client"

[expect.graph]
must_include = [["myapp.request", "myapp.db_query"]]
acyclic = true

[expect.hermeticity]
no_external_services = true
resource_attrs_must_match = { "service.name" = "myapp" }
```

**Key Features:**
- **Zero flakiness** - Deterministic validation across environments
- **5-Dimensional validation** - Structural, temporal, cardinality, hermeticity, attribute
- **Span validators** - Existence, count, attributes, hierarchy, events, duration
- **Graph validators** - Parent-child relationships and cycle detection
- **Hermeticity validators** - External service detection and resource validation

**Example: Framework validates itself using its own telemetry - 100% deterministic!**

### **Advanced Validation Framework**

The framework provides comprehensive validation across multiple dimensions:

- **Structural Validation** - Span hierarchy and relationships
- **Temporal Validation** - Execution time windows and containment
- **Cardinality Validation** - Count constraints across execution paths
- **Hermeticity Validation** - Isolation and contamination detection
- **Attribute Validation** - Semantic metadata validation

**Result:** Proven correctness with zero false positives.

### **Fake-Green Detection** *(v1.0)*

**The Problem:** Tests that report "PASS" but never actually executed code.

**The Solution:** OTEL-first validation with 7 independent detection layers:

```toml
# Tests must PROVE they executed by generating telemetry
[[expect.span]]
name = "container.exec"
events.any = ["container.start", "container.exec", "container.stop"]

[expect.graph]
must_include = [["test.run", "container.exec"]]

[expect.counts]
spans_total.gte = 2

[expect.status]
all = "OK"
```

**7 Detection Layers:**
1. **Lifecycle Events** - Container operations generated events
2. **Span Graph** - Parent-child relationships exist
3. **Span Counts** - Expected number of operations occurred
4. **Temporal Ordering** - Operations occurred in correct sequence
5. **Window Containment** - Child operations within parent timeframes
6. **Status Validation** - All operations completed successfully
7. **Hermeticity** - Tests run in isolation without external dependencies

**Analyze Traces:**
```bash
# Run test with OTEL
clnrm run test.toml --otel-endpoint http://localhost:4318

# Validate telemetry evidence
clnrm analyze test.toml traces.json
```

**Result:**
- ✅ **PASS** = Code actually executed with proof
- ❌ **FAIL** = Fake-green test detected (no evidence)

**Documentation:**

- [Developer Guide](docs/FAKE_GREEN_DETECTION_DEV_GUIDE.md) - How to extend it
- [TOML Schema](docs/FAKE_GREEN_TOML_SCHEMA.md) - Configuration reference
- [CLI Reference](docs/CLI_ANALYZE_REFERENCE.md) - Command usage

## 🎯 **Real Evidence - Not Claims**

### **Container Execution Works**
```bash
$ clnrm run
🚀 Executing test: basic_test
📋 Step 1: hello_world
🔧 Executing: echo Hello from cleanroom!
📤 Output: Hello from cleanroom!
✅ Output matches expected regex
✅ Step 'hello_world' completed successfully
🎉 Test 'basic_test' completed successfully!
```

### **Framework Self-Tests Work**
```bash
$ clnrm self-test
Framework Self-Test Results:
Total Tests: 5
Passed: 5
Failed: 0
✅ All framework functionality validated
```

### **Plugin Ecosystem Works**
```bash
$ clnrm plugins
📦 Available Service Plugins:
✅ generic_container (alpine, ubuntu, debian)
✅ surreal_db (database integration)
✅ network_tools (curl, wget, netcat)
```

## 🎯 **What Makes This Special**

### **Framework Self-Testing**
The framework tests itself through the "eat your own dog food" principle. Every feature is validated by using the framework to test its own functionality.

### **Hermetic Container Testing**
Unlike traditional testing frameworks, clnrm provides **true hermetic testing** where each test runs in completely isolated, real containers with no test interference.

### **Universal Test Definition**
Single `.clnrm.toml` files can test any technology stack - databases, APIs, microservices - all through containerized execution.
