# Mobile Chat navigation and pagination

> Native conversation browsing and scoped background loading.

## Conversation browsing

Mobile Chat retains the shared app shell and navigation while compact screens
switch between the conversation list and a selected thread. Wide screens keep
both panes visible. The list remains scrollable with tall filter content.

Conversation pages load automatically when the remaining scroll distance falls
below three quarters of the viewport, including when the first page cannot fill
the screen. Only one automatic request is made for an unchanged scoped list;
failed or empty pages retain a manual Load more action rather than retrying in a
loop. The manual action also remains available when filters show no rows.

Pagination results and failures from an older workspace or refresh generation
cannot publish into the current list. Pending local rows continue to use the
existing scoped Chat collection overlay.

## Composer

Attachments use the adaptive sheet shared by compact and expanded mobile
surfaces. Send remains disabled while a message or attachment upload is in
flight, and the icon exposes a localized tooltip. This changes neither message
transport nor attachment permissions; live device and production verification
are still required for delivery.

Regression coverage: `chat_conversation_layout_test.dart`,
`chat_pagination_scope_test.dart`, and `chat_thread_layout_test.dart` in
`apps/mobile/test/features/chat`.
