# PR: PM Mode as Default - Phase 1 Implementation

**Status**: ✅ Ready for Review
**Test Coverage**: 26 tests, all passing
**Breaking Changes**: None

---

## 📋 Summary

This PR implements **Phase 1** of the PM-as-Default architecture: **PM Mode Initialization** and **Validation Infrastructure**.

### What This Enables

- ✅ **Automatic Context Contract generation** (project-specific rules)
- ✅ **Reflexion Memory system** (learning from mistakes)
- ✅ **5 Core Validators** (security, dependencies, runtime, tests, contracts)
- ✅ **Foundation for 4-phase workflow** (PLANNING/TASKLIST/DO/ACTION)

---

## 🎯 Problem Solved

### Before
- PM Mode was **optional** and rarely used
- No enforcement of project-specific rules (Kong, Infisical, .env禁止)
- Same mistakes repeated (no learning system)
- No pre-execution validation (implementations broke rules)

### After
- PM Mode **initializes automatically** at session start
- Context Contract **enforces rules** before execution
- Reflexion Memory **prevents recurring mistakes**
- Validators **block problematic code** before execution

---

## 🏗️ Architecture

### 1. PM Mode Init Hook

**Location**: `superclaude/core/pm_init/`

```python
from superclaude.core.pm_init import initialize_pm_mode

# Runs automatically at session start
init_data = initialize_pm_mode()
# Returns: Context Contract + Reflexion Memory + Project Structure
```

**Features**:
- Git repository detection
- Lightweight structure scan (paths only, no content reading)
- Context Contract auto-generation
- Reflexion Memory loading

---

### 2. Context Contract

**Location**: `docs/memory/context-contract.yaml` (auto-generated)

**Purpose**: Enforce project-specific rules

```yaml
version: 1.0.0
principles:
  use_infisical_only: true
  no_env_files: true
  outbound_through: kong
runtime:
  node:
    manager: pnpm
    source: lockfile-defined
validators:
  - deps_exist_on_registry
  - tests_must_run
  - no_env_file_creation
  - outbound_through_proxy
```

**Detection Logic**:
- Infisical → `no_env_files: true`
- Kong → `outbound_through: kong`
- Traefik → `outbound_through: traefik`
- pnpm-lock.yaml → `manager: pnpm`

---

### 3. Reflexion Memory

**Location**: `docs/memory/reflexion.jsonl`

**Purpose**: Learn from mistakes, prevent recurrence

```jsonl
{"ts": "2025-10-19T...", "task": "auth", "mistake": "forgot kong routing", "rule": "all services route through kong", "fix": "added kong route", "tests": ["test_kong.py"], "status": "adopted"}
```

**Features**:
- Add entries: `memory.add_entry(ReflexionEntry(...))`
- Search similar: `memory.search_similar_mistakes("kong routing")`
- Get rules: `memory.get_rules()`

---

### 4. Validators

**Location**: `superclaude/validators/`

#### ContextContractValidator
- Enforces project-specific rules
- Checks .env file creation (禁止)
- Detects hardcoded secrets
- Validates Kong/Traefik routing

#### DependencySanityValidator
- Validates package.json/pyproject.toml
- Checks package name format
- Detects version inconsistencies

#### RuntimePolicyValidator
- Validates Node.js/Python versions
- Checks engine specifications
- Ensures lockfile consistency

#### TestRunnerValidator
- Detects test files in changes
- Runs tests automatically
- Fails if tests don't pass

#### SecurityRoughcheckValidator
- Detects hardcoded secrets (Stripe, Supabase, OpenAI, Infisical)
- Blocks .env file creation
- Warns on unsafe patterns (eval, exec, shell=True)

---

## 📊 Test Coverage

**Total**: 26 tests, all passing

### PM Init Tests (11 tests)
- ✅ Git repository detection
- ✅ Structure scanning
- ✅ Context Contract generation (Infisical, Kong, Traefik)
- ✅ Runtime detection (Node, Python, pnpm, uv)
- ✅ Reflexion Memory (load, add, search)

### Validator Tests (15 tests)
- ✅ Context Contract validation
- ✅ Dependency sanity checks
- ✅ Runtime policy validation
- ✅ Security roughcheck (secrets, .env, unsafe patterns)
- ✅ Validator chain (all pass, early stop)

```bash
# Run tests
uv run pytest tests/core/pm_init/ tests/validators/ -v

# Results
============================== 26 passed in 0.08s ==============================

## 🚀 Usage

### Automatic Initialization

```python
# Session start (automatic)
from superclaude.core.pm_init import initialize_pm_mode

init_data = initialize_pm_mode()

# Returns
{
    "status": "initialized",
    "git_root": "/path/to/repo",
    "structure": {...},  # Docker, Infra, Package managers
    "context_contract": {...},  # Project-specific rules
    "reflexion_memory": {
        "total_entries": 5,
        "rules": ["all services route through kong", ...],
        "recent_mistakes": [...]
    }
}
```

### Manual Validation

```python
from superclaude.validators import (
    ContextContractValidator,
    SecurityRoughcheckValidator,
    ValidationStatus
)

# Create validator
validator = SecurityRoughcheckValidator()

# Validate changes
result = validator.validate({
    "changes": {
        ".env": "SECRET_KEY=abc123"
    }
})

# Check result
if result.failed:
    print(result.message)  # "CRITICAL security issues detected"
    print(result.details)  # {"critical": ["❌ .env file detected"]}
    print(result.suggestions)  # ["Remove hardcoded secrets", ...]
```

### Reflexion Memory

```python
from superclaude.core.pm_init import ReflexionMemory, ReflexionEntry

memory = ReflexionMemory(git_root)

# Add entry
entry = ReflexionEntry(
    task="auth implementation",
    mistake="forgot kong routing",
    evidence="direct connection detected",
    rule="all services must route through kong",
    fix="added kong service in docker-compose.yml",
    tests=["test_kong_routing.py"]
)
memory.add_entry(entry)

# Search similar mistakes
similar = memory.search_similar_mistakes("kong routing missing")
# Returns: List[ReflexionEntry] with similar past mistakes

# Get all rules
rules = memory.get_rules()
# Returns: ["all services must route through kong", ...]
```
