Internals
Engineering notes on how the app's features are built: the routes and components involved, how data flows between them, and the gaps that are known and not yet closed. Written for someone about to change the code.
The Features section covers the same ground for someone about to use the app. When behaviour changes, both sections need updating — the feature page for what a user sees, the internals page for how it happens.
Each page follows the same shape:
- Route / Package / Component — where the feature lives.
- What it shows — the user-visible behaviour, precisely.
- Data flow — the call chain, from persisted state to rendered panel.
- Known gaps — what is deliberately not done yet.
