• log_security_event() - Security event logging (authentication, authorization)

Technical Details

This phase standardized logging across the application for better observability:

1. Consistent Logger Initialization: Every module uses logging.getLogger(__name__)
2. Centralized Utilities: Structured logging functions in apps.core.logging
3. Contextual Logging: All logs include relevant context (user, request, operation)
4. Security Logging: Dedicated logging for security events
5. Performance Logging: Query performance and cache hit/miss tracking

Logging Patterns:

• Exception handlers use log_exception() with context
• FSM transitions use log_business_event()
• Authentication events use log_security_event()
• Never log sensitive data (passwords, tokens, PII)

Benefits:

• Easier debugging with consistent log format
• Better production monitoring with structured logs
• Security audit trail for compliance
• Performance insights from cache and query logs

Technical Details

This phase focused on documentation-only changes to align all project documentation with the actual Django + HTMX architecture. No code changes were made.

Key Corrections:

• The project uses Django templates with HTMX for interactivity, not a Vue.js SPA
• There is no separate frontend build process - static files are served by Django
• The API serves both JSON (for mobile/integrations) and HTML (for HTMX partials)
• Authentication uses JWT for API access and sessions for web browsing
