Propagation sync (microReticulum submodule):
- Fix msgpack interop: send nil (not 0) for per_transfer_limit so
Python server doesn't reject all messages as exceeding "0 KB limit"
- Fix Resource response routing: extract request_id from packed data
when not present in Resource advertisement, route to pending request
callback instead of generic concluded handler
- Fix Link::request() to manually build packed arrays, avoiding
Bytes::to_msgpack() BIN-wrapping that breaks protocol interop
UI enhancements:
- PropagationNodesScreen: manual node entry via 32-char hex hash in
search field, with paste support and radio button selection
- StatusScreen: display stamp cost from propagation node
- UIManager: NVS persistence for selected propagation node, proactive
path request on node selection, sync state machine with timeout
handling

Only destinations that have exchanged messages are written to SPIFFS.
UIManager marks destinations as persistent on send_message() and
on_message_received(). Reduces persist time from 40-50s to <1s.

Reduces crash rate from every 60-85s to 1 reboot per 6+ minutes.
Zero WDT triggers in 10-minute stability test.
BLE mutex fixes (BLEInterface.cpp):
- Release _mutex before blocking GATT ops in onConnected() and
onServicesDiscovered() — prevents 5-30s main-loop stalls during
service discovery, notification subscribe, identity exchange
- Non-blocking try_lock() for peerCount(), getConnectedPeerSummaries(),
get_stats() — returns empty/default if BLE task holds mutex
- Write-without-response in initiateHandshake()
WDT and persistence (main.cpp, sdkconfig.defaults, microReticulum):
- 30s WDT timeout (up from 10s) for SPIFFS flash I/O headroom
- Register Identity::set_persist_yield_callback() to feed WDT every
5 entries during save_known_destinations() (70+ entries = 30-50s)
- WDT feeds between reticulum and identity persist calls
BLE host desync recovery (NimBLEPlatform):
- Time-based desync tracking instead of aggressive counter-based reboot
- 60s tolerance without connections, 5 minutes with active connections
(data still flows over existing BLE mesh links)
- Remove immediate recoverBLEStack() from 574 handler and
enterErrorRecovery() — let startScan() manage reboot decision
- Increase CONNECTION_COOLDOWN from 3s to 10s to reduce 574 risk
- Increase SCAN_FAIL_RECOVERY_THRESHOLD from 5 to 10

NimBLE crash fix:
- Patch ble_hs.c assert(0) in BLE_HS_SYNC_STATE_BRINGUP timer handler
via pre-build script (patch_nimble.py). The assert fires when a timer
callback races with host re-sync — harmless, but kills the ESP32 and
corrupts any file writes in progress.
Persistence fixes (in microReticulum submodule):
- Atomic save: write to temp file then rename, protecting existing data
- Fast persist: 5s after dirty flag instead of waiting 60s interval
- Corrupt file recovery: delete invalid files, recover from temp files
- INFO-level logging for load/save visibility
Other:
- Wrap LXMF announce in try/catch for crash safety
- Call Identity::should_persist_data() from main loop

Fix systemic One Definition Rule violation where BLEInterface.h included
headers from deps/microReticulum/src/BLE/ while .cpp files compiled
against local lib/ble_interface/ versions, causing struct layout mismatches
(PeerInfo field shifting corrupted conn_handle/mtu) and class layout
mismatches (BLEPeerManager member differences caused LoadProhibited crash).
Key fixes:
- Include local BLE headers instead of deps versions in BLEInterface.h
- Sync PeerInfo keepalive tracking fields and BLETypes constants with deps
- Shutdown re-entrancy guard and proper client cleanup via deinit(true)
- Host sync checks before scan, advertise, and connect operations
- Avoid deadlock by deferring _on_connected from NimBLE host task
- Duplicate identity detection, stale handle cross-check in keepalives
- Bounds validation on conn_handle in setPeerHandle/promoteToIdentityKeyed
- Periodic persist_data() call for display name persistence across reboots

- Fix link packet routing in microReticulum to only transmit on the
link's attached interface (was flooding all interfaces including LoRa)
- Batch up to 8 Codec2 frames per Reticulum packet to reduce per-packet
encryption/transport overhead (~3 packets/sec instead of 25)
- Add TX diagnostics: hex dump of first 2 packets, per-interval stats
with link status, idle/drop warnings
- Audio now reaches remote end (TX=325 frames in 12s test call)

Replace custom ES7210 register-level driver with the verbatim LilyGO
T-Deck Plus ES7210 library. The custom driver was writing MODE_CONFIG
and clock doubler registers (master mode path) which broke the ES7210's
clock chain, causing all-zero PCM output. The LilyGO library in slave
mode leaves those registers at power-on defaults, which is correct since
the ESP32 I2S master provides MCLK/BCLK/LRCK.
Also includes LXST voice call protocol improvements:
- LXST IN destination for receiving calls
- Announce handler for tracking voice-capable peers
- Path request before outgoing calls
- Throttled SPIFFS saves in microReticulum (dirty flag)

- Fix slow screen wake: track screen_off_time and wake on any activity
newer than when screen turned off (was requiring activity <1s ago)
- Add MEMORY_MONITOR_POLL() to main loop for deferred logging
- Add NVS crash breadcrumb system for LXST call debugging
- Update microReticulum submodule (memory stability fixes)

- Replace std::map and std::vector with fixed-size pools in
BLEInterface (fragmenters, pending handshakes, pending data)
- Track keepalive failures and disconnect after 3 consecutive
- Force-disconnect zombie peers detected by BLEPeerManager
- Add periodic advertising refresh (every 60s) to combat silent stops
- Buffer incoming data when identity not yet mapped instead of dropping
- Subtract ATT_OVERHEAD from MTU in NimBLEPlatform connection setup

Update microReticulum submodule: static pool arrays (~20 pools) moved
from BSS segment to PSRAM via heap_caps_aligned_alloc at startup.
Before: boot heap ~116KB, steady-state max_block 7.6KB, constant skipped announces
After: boot heap ~161KB, steady-state max_block 65KB, zero skipped announces

- activate_link null guard and copy-before-remove
- Known destinations pool increased to 2048 slots
- Proactive culling at 90% threshold
- Low-memory guard for resource retries on ESP32

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.
