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.

Display and LoRa were creating separate SPIClass(HSPI) instances which
claimed GPIO pins via the matrix, preventing SD card (on FSPI) from
accessing MISO after Display init. Now all three peripherals use the
global SPI (FSPI) instance, eliminating GPIO routing conflicts.
- Display: use &SPI instead of new SPIClass(HSPI)
- SX1262Interface: use &SPI instead of new SPIClass(HSPI)
- SDAccess: enable format_if_empty for unformatted cards
Verified on device: SD (128GB SDHC), display, and LoRa all coexist.

The T-Deck Plus shares HSPI across the display (CS=12), LoRa (CS=9),
and SD card (CS=39). Previously SD logging was disabled because
SD.begin() reconfigured the SPI bus and blanked the display.
This introduces a FreeRTOS mutex created in main.cpp and injected into
Display, SX1262Interface, and a new SDAccess class so all three
peripherals serialize their SPI transactions safely.
- Add SDAccess class wrapping SD.begin() and file ops with mutex
- Add set_spi_mutex() to Display and SX1262Interface
- Wrap Display flush, fill, draw, and power ops in mutex
- Refactor SDLogger to use SDAccess mutex instead of owning SD.begin()
- Wire up mutex creation and injection order in setup()

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.
