Trail Mate Dev
6e613e382e
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 application configuration ownership
|
|
|
|
An installed CM0 form test exposed Reticulum group edits disappearing after Save.
|
|
The SDL input path displayed the exact mixed-case/punctuation text, but the
|
|
group did not survive the apply operation. The service regression reproduced
|
|
the same loss without the UI: `applyMeshConfig()` reloaded the legacy TSV file
|
|
over the just-edited application configuration.
|
|
|
|
The application snapshot is now the runtime owner of Reticulum groups, matching
|
|
the production configuration model. Applying mesh configuration never reloads
|
|
the old file. Snapshot version 3 records this ownership, including an intentionally
|
|
empty group list. Version 2 snapshots remain readable. At startup, an old empty
|
|
snapshot can import the legacy TSV once; an already populated snapshot takes
|
|
precedence. The migration also works while another mesh protocol is active.
|
|
The legacy source is retained, and an unavailable load is not marked migrated
|
|
by the startup loader. A version 3 empty list does not resurrect deleted old groups.
|
|
|
|
The explicit SDL and Cardputer loops call `updateCoreServices()` rather than the
|
|
convenience `tick()` entry point. Debounced persistence now runs in that common
|
|
update path, so both loop styles save while the app is running. Shutdown retains
|
|
the existing immediate-flush behavior.
|
|
|
|
On 22 October 2026 native loading was changed to distinguish a missing working
|
|
value from invalid or unavailable storage. Only a missing value admits the
|
|
first-start defaults and legacy migration. Wrong kind/size, unsupported header
|
|
or version, and storage errors stop initialization without replacing the
|
|
working value. Supported version-2 migration remains covered. Reset-marker
|
|
reads also use the strict boolean port, preventing malformed metadata from
|
|
authorizing a discarded group source. See
|
|
[strict native settings reads](linux-strict-settings-reads.md) for the current
|
|
regressions, installed package and incomplete TMS integration scope.
|
|
|
|
## Regression verification
|
|
|
|
The new service test first failed because applying settings restored the old
|
|
group name. It now verifies live edits, durable storage before shutdown through
|
|
the explicit loop, process-owner reconstruction, modern snapshot precedence,
|
|
intentional deletion, and version 2-to-3 migration. The rebuilt native suite
|
|
passed 110/110 tests and Cardputer passed 14/14. Platform UI boundaries and ESP
|
|
stack hygiene passed. The standard armhf deb uses the target Raspbian C++ ABI
|
|
overlay; its SHA-256 is
|
|
`a0bb12f044bdd7d12a952c6280ce3dd7781a09d4aba74fe7b8ce6e54152ba636`.
|
|

|
## Installed CM0 form verification
|
|
|
|
The exact package was installed and passed `dpkg -V`. In an isolated local-mode
|
|
Wayland session, Tab/Enter opened Contacts, pointer actions selected Groups and
|
|
Add Group, and virtual keyboard input entered `CM0 Ab!9` plus a test destination
|
|
hash. The actual form displayed the expected case and punctuation. Before the
|
|
fix, Save closed the form but the record disappeared and the isolated database
|
|
contained no matching name. After the fix, the list displayed the new record and
|
|
the isolated SQLite database contained the exact name. A fresh application process
|
|
with no diagnostic preload displayed the same saved group again. Settings, cache
|
|
and SD roots were isolated for the successful save/reload test. No chat or radio
|
|
message was sent. This verifies the installed compositor/input/editor/config
|
|
path, not physical keyboard switches or touchscreen electrical behavior.
|
|
|
|
The saved group then opened the shared Chat compose screen, where `Draft Ab!9`
|
|
was entered and visually confirmed in the actual text area without pressing
|
|
Send. Final focused fullscreen Alt+F4 exited with status zero in 1.132 seconds.
|
|
RTC readiness/system-source remained valid with a zero-second UTC difference;
|
|
no device reboot was performed for this change.
