## Patch Boundary

Keep nexo-specific changes outside this snapshot where possible. This app is a
Mattermost mobile reference clone for runtime verification, not the nexo
product app surface.

Do not add app-specific nexo product UI or business logic here. Prefer docs,
test evidence, wrapper scripts, or small compatibility patches when the clone
is needed for runtime validation.

## Update Gate

A Mattermost mobile snapshot update must stay separate from core and
push-proxy updates. Before a merge request, record the selected upstream
commit, review the snapshot diff, and run the relevant app smoke or test lane.

When app verification depends on local-only credentials or endpoints, record
only sanitized evidence in tracked docs and keep raw environment values outside
git.
