+# Why Hard Rails Matter
+
+## The Problem We Discovered
+
+In AI-assisted development, we found:
+
+1. **Process adherence fails** - Agents claim to do code review but miss critical issues
+2. **Manual review insufficient** - Even AI-assisted review missed hardcoded passwords, SQL injection
+3. **Scale breaks quality** - 50 issues in a single patch release despite explicit QA processes
+
+### Real-World Case Study
+
+**Production patch validation:**
+
+After explicit code review and QA processes, we discovered **50 issues**:
+
+**Security Issues (9):**
+- 4 hardcoded passwords committed to repository
+- 1 SQL injection vulnerability
+- World-readable .env files
+- XSS vulnerabilities (CSP unsafe-inline)
+
+**Type Safety Issues (11):**
+- TypeScript strict mode DISABLED (`"strict": false`)
+- ESLint explicitly ALLOWING any types (`no-explicit-any: 'off'`)
+- Missing return types
+- Type assertion overuse
+
+**Silent Failures (9):**
+- Errors swallowed in try/catch blocks
+- Functions returning wrong types on error
+- No error logging
+- Network failures treated as false instead of errors
+
+**Test Coverage Gaps (10):**
+- No test coverage requirements
+- No testing framework setup
+- Code shipped with 0% coverage
+
+**Build Failures (2):**
+- Code committed that doesn't compile
+- Tests committed that fail
+
+**Dependency Issues (6):**
+- Critical CVEs not caught
+- Version conflicts between packages
+
+## The Solution: Mechanical Enforcement
+
+Don't **ask** agents to:
+- "Please do code review"
+- "Make sure to run tests"
+- "Check for security issues"
+
+Instead, **BLOCK** commits that:
+- Have type errors
+- Contain hardcoded secrets
+- Don't pass tests
+- Have security vulnerabilities
+
+### Why This Works
+
+**Example: Type Safety**
+
+❌ **Process-based (fails):**
+```
+Human: "Please avoid using 'any' types"
+Agent: "I'll make sure to use proper types"
+*Agent uses any types anyway*
+```
+
+✅ **Mechanically enforced (works):**
+```
+Agent writes: const x: any = 123;
+Git hook runs: ❌ Error: no-explicit-any
+Commit blocked
+Agent must fix to proceed
+```
+
+The agent doesn't get to **claim** it followed the process. The automated gate **determines** if code is acceptable.
+
+## Design Principles
+
+### 1. Fail Fast
+
+Detect issues at commit time, not in CI, not in code review, not in production.
+
+**Timeline:**
+- ⚡ Commit time: Type errors, lint errors, secrets → **BLOCKED**
+- 🔄 CI time: Build failures, test failures, CVEs → **BLOCKED**
+- 👀 Code review: Architecture, design, business logic
+- 🚀 Production: (Issues should never reach here)
+
+### 2. Non-Negotiable
+
+No agent can bypass enforcement. No "skip hooks" flag. No emergency override.
+
+If the code doesn't pass gates, it doesn't get committed. Period.
+
+### 3. Portable
+
+Same enforcement across:
+- All projects
+- All developers (human + AI)
+- All environments (local, CI, production)
+
+### 4. Minimal Friction
+
+Auto-fix where possible:
+- Prettier formats code automatically
+- ESLint --fix corrects simple issues
+- Only block when can't auto-fix
+
+### 5. Clear Feedback
+
+When enforcement blocks a commit, tell the agent:
+- ❌ What's wrong (type error, lint violation, etc.)
+- 📍 Where it is (file:line)
+- ✅ How to fix it (expected type, remove 'any', etc.)
+
+## Impact Prediction
+
+Based on a 50-issue production analysis:
+
+| Phase | Enforcement | Issues Prevented |
+|-------|-------------|------------------|
+| **Phase 1** | Pre-commit + strict mode + ESLint | 25 of 50 (50%) |
+| **Phase 2** | + CI expansion + npm audit | 35 of 50 (70%) |
+| **Phase 3** | + OWASP + coverage gates | 45 of 50 (90%) |
+
+**The remaining 10%** require human judgment:
+- Architecture decisions
+- Business logic correctness
+- User experience
+- Performance optimization
+
+## Agent Behavior Evolution
+
+### Before Quality Rails
+```
+Agent: "I've completed the feature and run all tests"
+Reality: Code has type errors, no tests written, hardcoded password
+Result: 50 issues discovered in code review
+```
+
+### After Quality Rails
+```
+Agent writes code with 'any' type
+Git hook: ❌ no-explicit-any
+Agent rewrites with proper type
+Git hook: ✅ Pass
+
+Agent writes code with hardcoded password
+Git hook: ❌ Secret detected
+Agent moves to environment variable
+Git hook: ✅ Pass
+
+Agent commits without tests
+CI: ❌ Coverage below 80%
+Agent writes tests
+CI: ✅ Pass
+```
+
+**The agent learns:** Good code passes gates, bad code is rejected.
+
+## Why This Matters for AI Development
+
+AI agents are **deterministically bad** at self-enforcement:
+- They claim to follow processes
+- They **believe** they're following processes
+- Output proves otherwise
+
+But AI agents are **good** at responding to mechanical feedback:
+- Clear error messages
+- Specific line numbers
+- Concrete fix requirements
+
+Quality Rails exploits this strength and avoids the weakness.
+
+## Conclusion
+
+**Process compliance:** Agents claim → Output fails
+**Mechanical enforcement:** Gates determine → Output succeeds
+
+This is not philosophical. This is pragmatic. Based on 50 real issues from production code.
+
+Quality Rails exists because **process-based quality doesn't work at scale with AI agents.**
+
+Mechanical enforcement does.

+# Quality Rails
+
+Portable quality enforcement for TypeScript, Python, and Node.js projects.
+
+## 🎯 What This Prevents
+
+Based on real-world validation of 50 issues in a production codebase:
+- ❌ Hardcoded passwords
+- ❌ SQL injection vulnerabilities
+- ❌ Type safety violations (`any` types)
+- ❌ Missing test coverage
+- ❌ Build failures
+- ❌ Dependency vulnerabilities
+
+**70% of these issues are prevented mechanically with quality-rails.**
+
+## ⚡ Quick Start (Mosaic)
+
+### New Project
+```bash
+# Apply template from Mosaic
+~/.mosaic/bin/mosaic-quality-apply --template typescript-node --target /path/to/project
+
+# Install dependencies
+cd /path/to/project
+npm install
+
+# Initialize git hooks
+npx husky install
+
+# Verify enforcement is working
+~/.mosaic/bin/mosaic-quality-verify --target /path/to/project
+```
+
+### Existing Project
+```bash
+# Same as above - works for new or existing projects
+~/.mosaic/bin/mosaic-quality-apply --template typescript-node --target /path/to/existing-project
+```
+
+## 🛡️ What You Get
+
+✅ **TypeScript strict mode** - All type checks enabled
+✅ **ESLint blocking `any` types** - no-explicit-any: error
+✅ **Pre-commit hooks** - Type check + lint + format before commit
+✅ **Secret scanning** - Block hardcoded passwords/API keys
+✅ **CI/CD templates** - Woodpecker, GitHub Actions, GitLab
+✅ **Test coverage enforcement** - 80% threshold
+✅ **Security scanning** - npm audit, OWASP checks
+
+## 📦 Available Templates
+
+| Template | Language | Framework | Status |
+|----------|----------|-----------|--------|
+| `typescript-node` | TypeScript | Node.js | ✅ Ready |
+| `typescript-nextjs` | TypeScript | Next.js | ✅ Ready |
+| `monorepo` | TypeScript | TurboRepo + pnpm | ✅ Ready |
+| `python` | Python | - | 🚧 Coming Soon |
+
+### Monorepo Template
+
+Perfect for projects combining **Next.js frontend** + **NestJS backend** in one repository.
+
+Features:
+- 🎯 **Multi-package aware** - lint-staged only checks changed packages
+- ⚡ **TurboRepo caching** - Faster builds and tests
+- 🔀 **Parallel dev servers** - Run web + API simultaneously
+- 📦 **pnpm workspaces** - Efficient dependency management
+- 🛡️ **Package-specific rules** - Next.js and NestJS get appropriate ESLint configs
+
+Example structure:
+```
+monorepo/
+├── apps/
+│   ├── web/    # Next.js frontend
+│   └── api/    # NestJS backend
+└── packages/
+    ├── shared-types/
+    ├── ui/
+    └── config/
+```
+
+## 🧪 How It Works
+
+### Pre-Commit (Local Enforcement)
+```bash
+# You try to commit code with a type error
+git commit -m "Add feature"
+
+# Quality rails blocks it:
+❌ Type error: Type 'number' is not assignable to type 'string'
+❌ ESLint: Unexpected any. Specify a different type.
+✋ Commit blocked - fix errors and try again
+```
+
+### CI/CD (Remote Enforcement)
+```yaml
+# Woodpecker pipeline runs:
+✓ npm audit (dependency security)
+✓ eslint (code quality)
+✓ tsc --noEmit (type checking)
+✓ jest --coverage (tests + coverage)
+✓ npm run build (compilation)
+
+# If any step fails, merge is blocked
+```
+
+## 🎓 Philosophy
+
+**Process compliance doesn't work.**
+
+Instructing AI agents to "do code review" or "run tests" fails. They claim to follow processes but output quality doesn't match claims.
+
+**Mechanical enforcement works.**
+
+Quality rails don't ask agents to follow processes. They **block commits** that don't pass automated checks.
+
+- Type errors? → **Commit blocked**
+- Hardcoded secrets? → **Commit blocked**
+- Test failures? → **Commit blocked**
+- Missing coverage? → **Commit blocked**
+
+This works for **any agent runtime** (Codex, Claude, OpenCode, Gemini, etc.) because enforcement is mechanical, not instructional.

+# CI/CD Configuration Guide
+
+Configure Woodpecker CI, GitHub Actions, or GitLab CI for quality enforcement.
+
+## Woodpecker CI
+
+Quality Rails includes `.woodpecker.yml` template.
+
+### Pipeline Stages
+
+1. **Install** - Dependencies
+2. **Security Audit** - npm audit for CVEs
+3. **Lint** - ESLint checks
+4. **Type Check** - TypeScript compilation
+5. **Test** - Jest with coverage thresholds
+6. **Build** - Production build
+
+### Configuration
+
+No additional configuration needed. Push to repository and Woodpecker runs automatically.
+
+### Blocking Merges
+
+Configure Woodpecker to block merges on pipeline failure:
+1. Repository Settings → Protected Branches
+2. Require Woodpecker pipeline to pass
+
+## GitHub Actions
+
+Copy from `templates/typescript-node/.github/workflows/quality.yml`:
+
+```yaml
+name: Quality Enforcement
+
+on: [push, pull_request]
+
+jobs:
+  quality:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+        with:
+          node-version: 20
+      - run: npm ci
+      - run: npm audit --audit-level=high
+      - run: npm run lint
+      - run: npm run type-check
+      - run: npm run test -- --coverage
+      - run: npm run build
+```
+
+### Blocking Merges
+
+1. Repository Settings → Branches → Branch protection rules
+2. Require status checks to pass: `quality`
+
+## GitLab CI
+
+Copy from `templates/typescript-node/.gitlab-ci.yml`:
+
+```yaml
+stages:
+  - install
+  - audit
+  - quality
+  - build
+
+install:
+  stage: install
+  script:
+    - npm ci
+
+audit:
+  stage: audit
+  script:
+    - npm audit --audit-level=high
+
+lint:
+  stage: quality
+  script:
+    - npm run lint
+
+typecheck:
+  stage: quality
+  script:
+    - npm run type-check
+
+test:
+  stage: quality
+  script:
+    - npm run test -- --coverage
+
+build:
+  stage: build
+  script:
+    - npm run build
+```
+
+## Coverage Enforcement
+
+Configure Jest coverage thresholds in `package.json`:
+
+```json
+{
+  "jest": {
+    "coverageThreshold": {
+      "global": {
+        "branches": 80,
+        "functions": 80,
+        "lines": 80,
+        "statements": 80
+      }
+    }
+  }
+}
+```
+
+CI will fail if coverage drops below threshold.
+
+## Security Scanning
+
+### npm audit
+
+Runs automatically in CI. Adjust sensitivity:
+
+```bash
+npm audit --audit-level=moderate  # Block moderate+
+npm audit --audit-level=high      # Block high+critical only
+npm audit --audit-level=critical  # Block critical only
+```
+
+### Snyk Integration
+
+Add to CI for additional security:
+
+```yaml
+- run: npx snyk test
+```
+
+Requires `SNYK_TOKEN` environment variable.
+
+## Notification Setup
+
+### Woodpecker
+
+Configure in Woodpecker UI:
+- Slack/Discord webhooks
+- Email notifications
+- Status badges
+
+### GitHub Actions
+
+Add notification step:
+
+```yaml
+- name: Notify on failure
+  if: failure()
+  run: |
+    curl -X POST $WEBHOOK_URL -d "Build failed"
+```
+
+## Troubleshooting
+
+**Pipeline fails but pre-commit passed:**
+- CI runs all packages, pre-commit only checks changed files
+- Fix issues in all packages, not just changed files
+
+**npm audit blocks on low-severity:**
+- Adjust `--audit-level` to `moderate` or `high`
+
+**Coverage threshold too strict:**
+- Lower thresholds in package.json
+- Add coverage exceptions for specific files

+# TypeScript Project Setup Guide
+
+Step-by-step guide to add Quality Rails to a TypeScript project.
+
+## Prerequisites
+
+- Node.js 18+ and npm/pnpm
+- Git repository initialized
+- TypeScript project (or create with `npm init` + `tsc --init`)
+
+## Installation
+
+### 1. Clone Quality Rails
+
+```bash
+git clone git@git.mosaicstack.dev:mosaic/quality-rails.git
+```
+
+### 2. Run Installation Script
+
+```bash
+# From your project directory
+../quality-rails/scripts/install.sh --template typescript-node --target .
+```
+
+This copies:
+- `.husky/pre-commit` - Git hooks
+- `.lintstagedrc.js` - Pre-commit checks
+- `.eslintrc.js` - Strict ESLint rules
+- `tsconfig.json` - TypeScript strict mode
+- `.woodpecker.yml` - CI pipeline
+
+### 3. Install Dependencies
+
+Add to your `package.json`:
+
+```json
+{
+  "scripts": {
+    "lint": "eslint 'src/**/*.{ts,tsx}' --max-warnings=0",
+    "type-check": "tsc --noEmit",
+    "test": "jest",
+    "build": "tsc",
+    "prepare": "husky install"
+  },
+  "devDependencies": {
+    "@typescript-eslint/eslint-plugin": "^7.0.0",
+    "@typescript-eslint/parser": "^7.0.0",
+    "eslint": "^9.0.0",
+    "eslint-config-prettier": "^9.0.0",
+    "eslint-plugin-prettier": "^5.0.0",
+    "eslint-plugin-security": "^3.0.0",
+    "husky": "^9.1.7",
+    "jest": "^29.0.0",
+    "lint-staged": "^16.2.7",
+    "prettier": "^3.0.0",
+    "typescript": "^5.6.0"
+  }
+}
+```
+
+Then run:
+```bash
+npm install
+npx husky install
+```
+
+### 4. Verify Enforcement
+
+```bash
+../quality-rails/scripts/verify.sh
+```
+
+Should output:
+```
+✅ PASS: Type errors blocked
+✅ PASS: 'any' types blocked
+✅ PASS: Lint errors blocked
+```
+
+## What Gets Enforced
+
+### TypeScript Strict Mode
+
+All strict checks enabled in `tsconfig.json`:
+
+```json
+{
+  "compilerOptions": {
+    "strict": true,
+    "noImplicitAny": true,
+    "strictNullChecks": true,
+    "strictFunctionTypes": true,
+    "strictBindCallApply": true,
+    "strictPropertyInitialization": true,
+    "noImplicitThis": true,
+    "alwaysStrict": true,
+    "noUnusedLocals": true,
+    "noUnusedParameters": true,
+    "noImplicitReturns": true,
+    "noFallthroughCasesInSwitch": true,
+    "noUncheckedIndexedAccess": true,
+    "noImplicitOverride": true,
+    "noPropertyAccessFromIndexSignature": true
+  }
+}
+```
+
+### ESLint Rules
+
+Key rules in `.eslintrc.js`:
+
+```javascript
+{
+  '@typescript-eslint/no-explicit-any': 'error',              // Block 'any' types
+  '@typescript-eslint/explicit-function-return-type': 'warn', // Require return types
+  '@typescript-eslint/no-floating-promises': 'error',         // Catch unhandled promises
+  '@typescript-eslint/no-misused-promises': 'error',          // Prevent promise misuse
+}
+```
+
+### Pre-Commit Checks
+
+On every `git commit`, runs:
+1. ESLint with --max-warnings=0
+2. TypeScript type check
+3. Prettier formatting
+4. Secret scanning (if git-secrets installed)
+
+If any fail → **commit blocked**.
+
+## Troubleshooting
+
+### "husky - pre-commit hook exited with code 1"
+
+This means pre-commit checks failed. Read the error output:
+
+```
+src/example.ts:5:14 - error TS2322: Type 'number' is not assignable to type 'string'
+```
+
+Fix the error and commit again.
+
+### "Cannot find module '@typescript-eslint/parser'"
+
+Dependencies not installed:
+```bash
+npm install
+```
+
+### Pre-commit hooks not running
+
+Husky not initialized:
+```bash
+npx husky install
+```
+
+## Customization
+
+See [CUSTOMIZATION.md](./CUSTOMIZATION.md) for adjusting strictness levels.
+
+## CI/CD Setup
+
+See [CI-SETUP.md](./CI-SETUP.md) for Woodpecker/GitHub Actions configuration.

+# Monorepo Structure
+
+This quality-rails monorepo template supports the following structure:
+
+```
+monorepo/
+├── apps/
+│   ├── web/                  # Next.js frontend
+│   │   ├── package.json
+│   │   ├── tsconfig.json     # extends ../../tsconfig.base.json
+│   │   └── .eslintrc.js      # extends ../../.eslintrc.strict.js
+│   └── api/                  # NestJS backend
+│       ├── package.json
+│       ├── tsconfig.json
+│       └── .eslintrc.js
+├── packages/
+│   ├── shared-types/         # Shared TypeScript types

+├── tsconfig.base.json        # Base TypeScript config
+├── turbo.json                # TurboRepo configuration
+├── pnpm-workspace.yaml       # pnpm workspaces
+└── package.json              # Root package with scripts
+```
+
+## Package-Specific Configs
+
+Each package extends the root configuration:
+
+**apps/web/tsconfig.json:**
+```json
+{
+  "extends": "../../tsconfig.base.json",
+  "compilerOptions": {
+    "lib": ["dom", "dom.iterable", "ES2022"],
+    "jsx": "preserve",
+    "noEmit": true,
+    "paths": {
+      "@/*": ["./*"]
+    }
+  },
+  "include": ["**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
+  "exclude": ["node_modules", ".next"]
+}
+```
+
+**apps/api/tsconfig.json:**
+```json
+{
+  "extends": "../../tsconfig.base.json",
+  "compilerOptions": {
+    "module": "commonjs",
+    "outDir": "./dist",
+    "rootDir": "./src",
+    "emitDecoratorMetadata": true,
+    "experimentalDecorators": true
+  },
+  "include": ["src/**/*"],
+  "exclude": ["node_modules", "dist", "test"]
+}
+```
+
+## Running Commands
+
+**All packages:**
+```bash
+npm run lint        # Lint all packages
+npm run type-check  # Type check all packages
+npm run test        # Test all packages
+npm run build       # Build all packages
+```
+
+**Single package:**
+```bash
+npm run lint --workspace=apps/web
+npm run dev --workspace=apps/api
+```
+
+**With TurboRepo:**
+```bash
+turbo run build           # Build with caching
+turbo run dev --parallel  # Run dev servers in parallel
+```
+
+## Pre-Commit Enforcement
+
+lint-staged automatically detects which packages contain modified files and runs:
+- ESLint on changed files
+- TypeScript check on affected packages
+- Prettier on all changed files
+
+Only runs checks on packages that have changes (efficient).
