Bumps microLXMF d7e05fd -> 82d2e54 (fork branch fix/sync-path-wait-backoff): LXMRouter::process_sync() PR_PATH_REQUESTED now re-polls Transport::has_path() at most once per PATH_REQUEST_WAIT instead of every main-loop iteration. In the CBA microStore-backed microReticulum fork has_path() is a FileStore exists() = a LittleFS read, so the old code issued a path-table read every ~2s for the whole 60s sync window while the propagation node was unreachable. Measured on the T-Deck: one destination fetched 293x in 600s (~every 2s), all on the same 2MB partition as message storage, with [DISP] flush stalls interleaved. Worst-case sync cycle cost drops from ~30 reads to ~3-4. The periodic message sync was already 4h default with a user setting (Settings 'Prop Sync Interval (hrs)', sync_int=14400) — unchanged. Adds tests/build_scripts/test_propagation_sync_poll_contract.py: pins the re-poll gate ordering, the PATH_REQUEST_WAIT window, the untouched one-shot check in request_messages_from_propagation_node, and enforces platformio.ini <-> audit-tool pin agreement.
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.
