# Logging Improvements Summary

## Overview

This analysis identified **12 critical areas** where PropertyWebBuilder's error handling and logging could be significantly improved. The application has a `StructuredLogger` service in place but it is severely underutilized in critical operations.

## Key Findings

### What's Good
- Authentication audit logging is well-implemented (AuthAuditLog)
- StructuredLogger service exists with JSON formatting
- Some Firebase token verification has decent logging

### What's Missing
- **Silent failures** in provisioning pipeline
- **No logging context** in external API calls (Firebase, ntfy, MLS)
- **Broad exception handling** that swallows errors (`rescue => e` with minimal logging)
- **Multi-tenant context missing** from most logs
- **Email/async delivery failures** invisible to users
- **Step-by-step logging absent** from critical operations

## Priority Fix List

### CRITICAL (Do First) - 4 Items
1. **Firebase Auth Service** (HIGH) - `app/services/pwb/firebase_auth_service.rb` line 38-47
   - Missing error logging for user creation and membership grant
   - Impacts: Authentication flow, user provisioning
   - Fix: ~10 lines of code

2. **Signup/Provisioning Flow** (HIGH) - `app/services/pwb/provisioning_service.rb` line 139-165
   - No step-by-step logging, seed pack failures silent

   - Fix: ~40 lines of logging statements

3. **Contact Form** (HIGH) - `app/controllers/pwb/contact_us_controller.rb` line 64-75
   - Catches broad exceptions, loses error context
   - Impacts: Inquiry submissions, notification failures
   - Fix: ~15 lines of code

4. **ntfyService** (HIGH) - `app/services/ntfy_service.rb` line 199-205
   - Network errors not distinguished, no timeout handling
   - Impacts: Security notifications, operational visibility
   - Fix: ~20 lines of code

### IMPORTANT (Do Next) - 5 Items
5. **MLS Integration** - `app/services/pwb/mls_connector.rb`
   - No error handling for RETS operations
   - Impacts: Property imports, business-critical feature
   - Fix: ~30 lines of code

6. **User Membership Service** - `app/services/pwb/user_membership_service.rb`
   - Silent success/failure on all operations
   - Impacts: Access control auditing
   - Fix: ~20 lines of code

7. **Import Controllers** - `app/controllers/pwb/import/` files
   - No validation logging, CSV failures silent
   - Impacts: Data import tracking
   - Fix: ~25 lines of code

8. **Auth Audit Log** - `app/models/pwb/auth_audit_log.rb` line 198-200
   - Swallows creation failures silently
   - Impacts: Audit trail integrity
   - Fix: ~5 lines of code

9. **Firebase Token Verifier** - `app/services/pwb/firebase_token_verifier.rb` line 76-96
   - Certificate fetch not properly tracked
   - Impacts: Firebase auth reliability
   - Fix: ~25 lines of code

### GOOD TO HAVE (Do Later) - 3 Items
10. **Firebase Login Controller** - `app/controllers/pwb/firebase_login_controller.rb`
11. **User Model Callbacks** - `app/models/pwb/user.rb` line 94-115
12. **Email Delivery Monitoring** - `app/controllers/pwb/contact_us_controller.rb` line 55-62

## Implementation Approach

### Phase 1: Critical Path (1-2 days)
- Focus on signup/provisioning pipeline (most customer-impacting)
- Add step logging to ProvisioningService
- Add error context to Firebase auth service
- Fix contact form broad exception handling
- Fix ntfy service network error handling

### Phase 2: Support Systems (1 day)
- MLS/RETS error handling
- Import controller logging
- User membership service logging
- Auth audit log failure handling
- Firebase token verifier certificate logging

### Phase 3: Refinement (0.5 day)
- Firebase login controller
- User model callbacks
- Email delivery monitoring
- Add tests for error paths

## Testing Strategy

For each fix, add tests verifying:
1. StructuredLogger is called with correct context
2. Errors are logged before being re-raised or suppressed
3. Multi-tenant context (website_id, user_id) is included
4. Different error types logged distinctly (timeout vs auth vs network)
5. No sensitive data logged (passwords, tokens, etc.)

Example test pattern:
```ruby
describe 'error logging' do
  it 'logs provisioning failures with context' do
    expect(StructuredLogger).to receive(:error).with(
      hash_including(
        website_id: website.id,
        error_class: 'StandardError'
      )
    )
    
    service.provision_website(website: website)
  end
end
```

## Rollout Plan

1. **Week 1**: Implement Phase 1 fixes (critical path)
   - Deploy to staging, verify logs are captured
   - Test error scenarios manually
   - Deploy to production

2. **Week 2**: Implement Phase 2 fixes (support systems)
   - Same testing approach
   - Monitor log aggregator for new fields

3. **Week 3**: Polish and refinement
   - Implement Phase 3
   - Add comprehensive tests
   - Create runbooks for common error scenarios

## Monitoring & Alerting

Once logging is improved, set up alerts for:
- `provisioning_service.*failed` errors (immediate alert)
- `firebase_auth_service.*failed` errors (immediate alert)
- `contact_form.*failed` with `email_delivery` flag (daily digest)
- `mls_connector.*failed` errors (hourly digest)
- `auth_audit_log.*failed` errors (immediate alert)

   - Implementation guidance
   - Read this for full context

2. **logging_quick_reference.md** (8 KB)
   - Ready-to-use code examples

   - Common patterns
   - Field reference
   - Start here for implementation

3. **LOGGING_IMPROVEMENTS_SUMMARY.md** (this file)
   - Executive summary
   - Priority list
   - Timeline
   - Testing approach

## Next Steps

1. **Review** the detailed analysis in `error_handling_logging_analysis.md`
2. **Plan sprints** using the priority list and time estimates
3. **Use code examples** from `logging_quick_reference.md` for implementation
4. **Test thoroughly** - error paths are often untested
5. **Deploy gradually** to catch any issues early
