Greptile round on ba5af76 (4/5) correctly rejected the first attempt:
the submitted-text marker was assigned in ChatScreen::on_send_clicked
AFTER the mailbox publish returned, so the main loop could take() +
admit the send and enter clear_composer() while the marker was still
empty — neither clearing the submitted text nor associating the commit
with its submission.
The marker is now recorded by the send callback itself
(UIManager::on_send_message_from_chat) immediately after the mailbox
accept, in the same LVGL lock section as the publish. The click handler
runs on the LVGL task with the LVGL mutex held (LVGLInit.cpp:160-179
wraps the whole lv_task_handler in the recursive mutex), so the marker
is visible to the main loop only after the mailbox entry is — the
take() + admit + clear sequence can never observe an empty marker for
an accepted send. clear_composer() additionally no-ops on an empty
marker, which is the retained-text path for rejected/retry sends.
The contract test is tightened to assert the marker is NOT assigned in
the click handler and IS assigned in the callback, so the race cannot
silently regress.
Verification: 181/181 contracts, tdeck + tdeck-release green.
Pyxis Tests
Three test surfaces, each runnable independently.
1. Pyxis-unique pytest suite
Native C++ tests of pyxis-unique code (BLE fragmenter, HDLC, etc.) and Python tests of build scripts.
/usr/bin/python3 -m pytest tests/build_scripts tests/native -v
System Python 3.9 has pytest pre-installed; Homebrew Python does not.

Adding a new native C++ test
Pattern: pure C++ unit + thin pytest wrapper.
- Write
tests/native/test_<thing>.cpp— include from../../{src,lib/...}for the unit under test, use the existingEXPECT_EQ/EXPECT_TRUE/RUN(name)framework, return non-zero on any failure. - If the unit pulls in microReticulum types, the shims in
tests/native/cover what's been needed so far:Bytes.h→bytes_shim.h(minimalRNS::Bytes— append/data/size/writable/resize/mid)Log.h(no-opTRACE/WARNING/INFO/ERRORmacros)Utilities/OS.h(OS::time()withset_fake_time()/clear_fake_time())
- Write
tests/native/test_<thing>.py— copy thetest_hdlc.pytemplate, swap source/include paths, run. - Confirm:
/usr/bin/python3 -m pytest tests/native/test_<thing>.py -v
2. LXST audio interop tests
Python tests verifying wire format and codec compatibility between pyxis (C++), Python LXST, and LXST-kt (Kotlin).
/usr/bin/python3 -m pytest tests/interop -v
Requires pycodec2 and access to $HOME/repos/public/LXST.
3. microReticulum native unit tests (PlatformIO)
The fork's microReticulum tests live under deps/microReticulum/test/ and run via PlatformIO Unity.
cd deps/microReticulum && pio test -e native17
Use native17, not native — the C++11 env is broken (static-constexpr ODR-use). Baseline as of 2026-05-02: 94/114 PASS, 7 FAIL, 5 SKIPPED, 7 suites ERRORED. The clean suites are
test_os, test_bytes, test_msgpack, test_crypto, test_filesystem, test_objects, test_interop, test_general, test_reference, test_example, test_collections.
