- retire 0018 (upstream 67151dfaf73 locks the shared multi-heap) and the hal_espressif PSRAM-realloc backport (in the new hal pin) - 0001: add LR1110/LR2021 to LORA_MODULE_BACKEND_NATIVE's depends on; upstream 1263266b615 gated it on its own radios and LR boards silently fell to loramac-node - ble: build the persisted gatt_peer settings key ourselves in the old format; bt_addr_le_to_str() changed to "P:AA:.." and would have orphaned every key and sent every bonded phone a Service Changed Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Architecture decision records
One decision per file: Context / Decision / Consequences / Status. Recorded 2026-09-25 at the end of the restructure; most describe decisions taken earlier. The system view is in ../DESIGN.md.
| # | Decision |
|---|---|
| 0001 | ESP32 boot: simple boot for plain builds, MCUboot for OTA builds and releases |
| 0002 | ESP32-S3 companions use native USB; start dfu restores USB-Serial-JTAG |
| 0003 | Devicetree overlays: board.overlay first, conf-paired after it |
| 0004 | BLE privacy off on nRF/MG24, on for ESP32-S3 (identity advertising) |
| 0005 | Track Zephyr main, pinned; the migration changes not to undo |
| 0006 | SX126x RX duty cycle and four-layer RX-busy gating |
| 0007 | Adaptive contention window instead of static tx/rx delays |
| 0008 | Storage layout, power-loss writes, BLE bonds in NVS |
| 0009 | WiFi companion boards and contact counts |
