Purpose: single entry point for all project docs with live links to the current sources. This index reflects the codebase as implemented, not legacy placeholders.

Codebase Snapshot

Backend (Django/DRF): Multi-tenant models inherit AccountBaseModel/SiteSectorBaseModel for automatic tenant scoping (backend/igny8_core/auth/models.py). API namespaces are wired in backend/igny8_core/urls.py: /api/v1/auth/, /api/v1/account/, /api/v1/planner/, /api/v1/writer/, /api/v1/system/, /api/v1/billing/ (tenant billing/invoices/credits), /api/v1/admin/ (billing admin + credit costs/stats), /api/v1/automation/, /api/v1/linker/, /api/v1/optimizer/, /api/v1/publisher/, /api/v1/integration/.
Frontend (React/Vite): Routing lives in frontend/src/App.tsx with lazy-loaded pages; account/billing pages at /account/plans, /account/billing, /account/purchase-credits, /account/settings, /account/team, /account/usage, plus tenant billing module routes under /billing/* and admin billing under /admin/*. Sidebar labels/paths are defined in frontend/src/layout/AppSidebar.tsx.

Known Documentation Gaps to Close

App-level architecture summary sourced from code (backend modules and frontend routes), including tenant scoping rules.
Billing/account accuracy pass: align docs to current endpoints in igny8_core/urls.py and admin aliases in modules/billing/admin_urls.py, plus the active frontend routes in App.tsx.
Frontend route/UX map for account/billing/admin sections tied to sidebar paths.
Multi-tenancy guardrails doc (account/site/sector isolation, role expectations) based on auth/models.py.
