# Release: Zero-Touch Architecture CLI v2.0.0

## Summary
Complete restructuring of the CLI to support Zero-Touch Architecture - automatic API discovery and attachment without manual intervention.

## Major Changes

### Removed (Breaking Changes)
- ❌ Removed manual `promote` and `demote` commands - these violated Zero-Touch principles
- ❌ Removed `promote()` and `demote()` methods from `BillingService`
- ❌ Removed obsolete `customer` and `promotion` CLI commands
- ❌ Renamed `core/` module to `billing/` for clarity

### Added

#### Infrastructure Management (`infra/`)
- ✅ `status` - Check CloudFormation stack and component health
- ✅ `trigger-discovery` - Manually invoke API discovery Lambda
- ✅ `list-apis` - List discovered APIs and their attachment status
- ✅ `verify` - Verify API attachments match expectations
- ✅ `attach` - Emergency manual API attachment
- ✅ `detach` - Emergency manual API detachment  
- ✅ `pause` - Disable EventBridge rules
- ✅ `resume` - Re-enable EventBridge rules

#### Monitoring (`monitor/`)
- ✅ `dashboard` - Real-time monitoring with auto-refresh
  - EventBridge rule status
  - Lambda invocation counts
  - Recent API discoveries
  - API Gateway metrics

#### AWS Operations (`aws/`)
- ✅ `lambda` - List, invoke, view logs, check errors
- ✅ `eventbridge` - List rules, view schedules, check states
- ✅ `apigateway` - List APIs, usage plans, check attachments
- ✅ `cloudwatch` - View logs, metrics, set up alarms

### Philosophy
The Zero-Touch Architecture means:
- APIs are automatically discovered every 5 minutes
- APIs are automatically attached to the correct usage plans based on tags
- Usage is automatically reported hourly to Stripe
- Manual intervention is only needed for emergency overrides

## Testing
- ✅ All 178 unit tests passing
- ✅ 89% code coverage (exceeds 70% requirement)
- ✅ Type checking passes with mypy
- ✅ All linting and formatting checks pass
- ✅ Pre-commit hooks configured and passing

## Migration Guide
1. Stop using `ai-billing promote/demote` commands
2. Deploy infrastructure stack with EventBridge rules
3. Use `ai-billing infra status` to verify deployment
4. Use `ai-billing monitor dashboard` to observe automatic operations
5. Emergency overrides available via `infra attach/detach` if needed

## Breaking Changes
- `promote` and `demote` commands no longer exist
- `core` module renamed to `billing`
- Service layer no longer has `promote()` and `demote()` methods

## Next Steps
1. Push to repository: `git push origin feat/cli-revamp`
2. Create PR for review
3. Deploy infrastructure stack with EventBridge rules
4. Monitor automatic discovery with `ai-billing monitor dashboard`
