+# App Shell Manifest: linux_cardputer_zero
+
+## Role
+
+Product app shell / target app shell.
+
+## Target Family
+
+Cardputer Zero portable Linux device.
+
+## Renderer Family
+
+Linux device renderer. The first build slice uses the shared ASCII/runtime
+adoption path so target identity and UX selection are build-closed before the
+framebuffer and evdev owner are promoted into this shell.
+
+## Board Facts
+
+- board id: `cardputerzero`
+- display: 320 x 170 logical pixels
+- input: built-in keyboard, real key mapping still needs device sampling
+- pointer/touch/trackball: not present in current board facts
+
+## Build Entrypoint
+
+- `builds/linux_cmake`
+
+## Responsibilities
+
+May:
+
+- select the `cardputerzero` target profile
+- select the Cardputer Zero device UX profile
+- bind Cardputer Zero board facts into Linux runtime startup
+- own future framebuffer, evdev, packaging, and launch details for this device
+
+Must not:
+
+- identify itself as a Linux simulator
+- depend on simulator demo data as product truth
+- define protocol, chat, map, or storage semantics
+- absorb shared Linux runtime code that belongs in `platform/linux/common`
+- hide missing real-device hardware integration behind simulator naming
+
+## Thin App Shell Entrypoint Declaration
+
+```text
+trail_mate_linux_cardputer_zero_start(target_profile)
+```
+
+## Current Status
+
+Device app shell baseline. This establishes the product target, board facts, UX
+selection, and CMake wiring. Real framebuffer, evdev, and device packaging are
+the next hardware-closure slices.

+# Cardputer Zero Linux App Shell
+
+This app shell is the Trail Mate product route for the Cardputer Zero portable
+Linux device. It is not the Linux simulator.
+
+The first slice intentionally keeps the runtime entry small: the shell validates
+the `cardputerzero` target profile, consumes the `boards/cardputerzero` facts,
+selects the `cardputer_compact` UX pack, and builds through
+`builds/linux_cmake`. That gives the device a real product boundary before the
+framebuffer, evdev, launch, and package owners are filled in.
+
+Known hardware facts in this repo:
+
+- display: 320 x 170 logical pixels
+- input: built-in keyboard
+- touch, pointer, and trackball: absent in current board facts
+
+The simulator remains a separate development shell under `apps/linux_sim_shell`.

+# UX Profile: cardputer_compact
+
+## Screen Class
+
+Compact 320 x 170 landscape keyboard device.
+
+## Input Model
+
+Keyboard-first input. Pointer, touch, and trackball are absent in the current
+Cardputer Zero board facts.
+
+## Feature Set
+
+Compact chat/status workflow with compact map and practical GPS/team actions.
+
+## Screen Set
+
+Dashboard, Chat, Compact Map/GPS, Team, Settings.
+
+## Map Mode
+
+Compact 320 x 170 landscape map with offline tiles and current-position focus.
+
+## Chat Mode
+
+Quick message chat list and compose optimized for keyboard entry.
+
+## Team Action Mode
+
+Quick location plus compact command/status actions.
+
+## GPS Mode
+
+Compact GPS status with route/tracker surfaces deferred.
+
+## Modal/Picker Strategy
+
+Keyboard-first compact modals and list pickers.
+
+## Renderer Family
+
+Executable UX pack `cardputer_compact`; current first Linux device-shell slice
+uses ASCII renderer until framebuffer ownership is validated.
+
+## Deferred Decisions
+
+Real-device keyboard sampling, framebuffer handoff, launch, and packaging remain
+deferred.
+
+Board describes. Target chooses. UX Pack presents. Renderer draws.
