Compose the CM0 fullscreen application and standard Debian package, align the Cardputer Zero shell, and share protocol, configuration, audio and storage services with embedded targets through existing platform seams. Add the paginated on-device TMAP creator using Center's published producer, private workspace recovery and direct keyboard shortcuts. Preserve unfinished management work behind its existing opt-in capability. Include native, ARM and shared-core regression fixtures, integration records, packaging helpers and dependency/license updates. Keep local build trees, device credentials, produced packages and validation logs outside version control. Validation before integration: ESP stack hygiene, Reticulum scope guard, staged whitespace checks and GitNexus scope audit. Prior device/build evidence and remaining hardware/package boundaries are recorded in the acceptance documents.

# Linux SDL pointer event delivery
|
|
|
|
The SDL host previously retained only the latest pointer position and pressed
|
|
state. A press and release arriving before the next LVGL sample therefore
|
|
looked like a release alone, losing quick clicks and taps. This was reproduced
|
|
both by a regression test and by a focused fullscreen application on the CM0:
|
|
an injected Wayland click on Chat left the application on the main menu.
|
|
|
|
The host now queues pointer samples and drains them through LVGL's
|
|
`continue_reading` mechanism. Press and release edges retain their positions;
|
|
only consecutive motion samples are coalesced. The queue is bounded to 64
|
|
samples. Overflow cancels the overloaded gesture with a release rather than
|
|
leaving the pointer held. Focus cancellation and rotation discard old samples.
|
|
This is a desktop input concern; shared pages and board profiles are unchanged.
|
|
|
|
The window regression first failed when a press/release pair produced no click.
|
|
After the fix, same-pump mouse clicks and finger taps pass under all four
|
|
rotations, alongside existing text, focus, PTT and window-exit checks. The platform
|
|
boundary check also passes. The updated armhf deb SHA-256 is
|
|
`03cf1ecd5742bcb28618b5a89cd4422f9ba422598f99a2dcf15e91a2de38eb59`.
|
|
It was installed and integrity-checked on CM0, preserving the original logo and
|
|
1232 by 568 P4 rendering. Repeating the same Wayland click now opens Messages;
|
|
the subsequent Menu click opens its Direct/Broadcast/Info popup. This establishes
|
|
the installed application/compositor/pointer path, not physical touchscreen
|
|
electrical or coordinate validation.
|
|
The final focused fullscreen Alt+F4 check exited with status zero in 0.749
|
|
seconds, and readback confirmed no application process remained after the
|
|
bounded navigation probes. Subsequent installed-page text entry, save and reload
|
|
verification is recorded in [Linux configuration persistence](linux-config-persistence.md);
|
|
the navigation probes above alone did not establish that behavior.
