- AnnounceListScreen::tick(): drop the pre-sort 64-item gather cap so the sort
always sees the true newest destinations (the path table is bounded by
USTORE_DEFAULT_MAX_RECS=400 and items allocate in PSRAM, so the gather is
bounded); only the render stays capped at MAX_DISPLAY.
- tick() now re-adds the freshly rendered item containers to the focus group and
focuses the first. The deferred gather meant show() (which adds widgets to the
group) ran before the containers existed and lv_obj_clean dropped the old ones,
so trackball navigation couldn't reach the list items.

Pins microReticulum to the fork's pyxis-fixes-on-0.4.1 @ b582986 (three 0.4.1-graft
regression fixes) and adds the pyxis-side pieces.
microReticulum fixes (via the pin):
- Identity::recall now accounts for the announce ratchet (matches validate_announce)
— it read app_data 32 bytes early for ratchet-bearing announces (Sideband/Columba),
garbling peer display names.
- DestinationEntry caps persisted random_blobs to PERSIST_RANDOM_BLOBS (16); the set
was never trimmed, growing path entries ~12B/re-announce past microStore's 1024B
ceiling so put() rejected them (empty path table) — and under a raised ceiling
bloated the FS until compaction crashed.
- Transport mirrors learned paths into _path_table so path_table() (the UI announce
list + T:PATHS) reflects them; the microStore migration stopped populating it.
pyxis pieces:
- -DUSTORE_DEFAULT_MAX_RECS=400 caps the live path-store record count (defense-in-depth).
- AnnounceListScreen::refresh() defers to a main-loop tick(): the gather (path-table
iteration + per-entry recall/app_data) runs off the LVGL lock, serialized with the
main-loop path-table writes, instead of racing them on the LVGL task and blocking
past the 5s lock timeout — which hung/crashed on open once the table was non-empty.
Verified on device: display names correct, T:PATHS 0 -> 11, no rejections, no
crashes, announce list opens cleanly.

Repins microReticulum + microLXMF onto the upstream-0.4.1 graft and adapts
pyxis to the new src/microReticulum/ layout and 0.4.x APIs. The far-diverged
0.3.0 fork's Resource/Transport/Identity work is subsumed by upstream's
reimplementation; only the still-needed fixes ride on the pinned branches
(PKCS7/HMAC/X25519 crypto -- proven byte-identical to python RNS 1.3.1 --
Packet link-proof callback, Identity short-sig guard, and the bz2 layer +
decompress-on-receive in Resource::assemble()).
Consumer-side changes:
- platformio.ini: pin microReticulum @2f21fee (pyxis-fixes-on-0.4.1) and
microLXMF @33760d0 (chore/microreticulum-0.4.1-layout); bump microStore
ceea8f5 -> c5fb69d (0.4.x requires the new BasicFileStore::init API);
-std=gnu++11 -> gnu++17 (upstream requires C++17).
- Namespace all microReticulum includes (angle + quote) to <microReticulum/...>
for the relocated layout; shim-local Utilities/Stream.h|Print.h preserved.
- Interface::send_outgoing now returns bool: update TCP/BLE/SX1262/Auto
overrides with correct success/failure returns.
- SDArchiveFileSystem::init(bool reformatOnFail=true) to match new microStore.
- Static Transport::get_path_table() -> path_table(); instance getter unchanged.
- Remove duplicate shim Cryptography/BZ2 (microReticulum provides it now; keep
lib/libbz2 as the ESP32 bzlib provider).
- patch_littlefs_paths.py: normalize microStore's LittleFS adapter paths to a
leading "/" -- ESP32 Arduino LittleFS rejects "./"-prefixed paths, which
silently broke the path store (no peer paths learned, all messaging blocked).
Validated on T-Deck Plus: builds (RAM 27.5% / Flash 77.7%), boots stable
(no WDT/panic), and a full on-device LXMF e2e (DIRECT + OPPORTUNISTIC +
bz2-compressed-Resource receive) passes 5/5.

relocate shim to lib/; pyxis lib API renames
Compile-tier graft progress on top of 40e561f. Key changes:
- Re-vendor lib/microreticulum-shim/ (was src-shim/) from the *actual*
ca355e5 commit content rather than the stale "feat/t-deck HEAD"
/tmp clone the previous commit pulled from. Recovers process_sync()
on LXMRouter and MEMORY_MONITOR_POLL macro that were missing.
- Move src-shim/ → lib/microreticulum-shim/ + add library.json so
PlatformIO discovers the .cpp files and links them. Was previously
only on the include path; the .cpps weren't in the build.
(This unblocks the 30+ undefined-reference linker errors for LXMF
and Instrumentation symbols.)
- Drop -Isrc-shim/Utilities (/Cryptography/Instrumentation) from
build_flags — they were over-broad and put our Stream.h on the
GLOBAL header path, breaking Arduino's Wire.cpp which has
`class TwoWire: public Stream`. -Ilib/microreticulum-shim alone
resolves subdir lookups via <Cryptography/X.h>, <Utilities/Y.h>.
- UniversalFileSystem migrated to microStore::Adapters::SPIFFSFileSystem
(activated by -DUSTORE_USE_SPIFFS). Vanilla upstream microReticulum
@ 0.3.0 deleted RNS::FileSystem in favor of microStore. Pyxis's
lib/universal_filesystem/ is now dead code on this build path.
- pyxis lib API renames for the post-graft world:
SDLogger.cpp: RNS::setLogCallback -> RNS::set_log_callback
AnnounceListScreen: Transport::get_destination_table ->
Transport::get_path_table
Transport::DestinationEntry ->
RNS::Persistence::DestinationEntry
UIManager.cpp: _lxst_destination ctor explicit RNS::Type::NONE
(vanilla Destination has no default ctor)
Identity::mark_persistent calls disabled w/
restoration TODO
ConversationListScreen: Interface::get_rssi/get_stats calls
disabled (the methods are non-virtual
on BLEInterface/SX1262Interface post
de-virtualization in a0ff631)
Compile is clean against the fixed-cryptography submodule pin; current
failure layer is fork-only Type::Channel constants referenced by the
vendored shim's Buffer/ChannelData files. That's the next session's
problem — see pyxis_microReticulum_graft_spike_findings.md for the
plan options (most likely: remove Channel/Buffer/ChannelData/Ratchet
from the shim, since LXMF doesn't use Channel anyway per the 2026-05-04
investigation).
Split T-Deck firmware from microReticulum examples/lxmf_tdeck/ into its
own repo. microReticulum is consumed as a git submodule dependency pinned
to feat/t-deck. All include paths updated from relative symlinks to bare
includes resolved via library build flags.
Both tdeck (NimBLE) and tdeck-bluedroid environments compile successfully.
