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
