Three-tier configuration hierarchy: - [env:base] — RadioLib + default LoRa parameters - [soc_esp32/esp32s3/nrf52] — platform + framework per SoC - [env:board_name] — board-specific pins + chip selection 20 boards across 4 vendors: - Heltec: 11 boards (T114, CT62, E213, E290, Mesh Solar, T190, Tracker, Tracker V2, V2, V3, V4) - LilyGo: 4 boards (T-Beam 1W, sx1262, sx1276, supreme) - Seeed: 1 board (Xiao S3 + Wio SX1262 with verified pins) - RAK: 4 boards (RAK11310, RAK3112, RAK3401, RAK3x72, RAK4631) Known/verified pins: Heltec V2/V3/V4, RAK4631, Seeed Xiao S3 FIXME pins: all others (placeholders for future research) Source skeleton: - config.h — compile-time defaults + pin validation (#error checks) - kiss.h/c — KISS protocol implementation (C99) - radio.h/cpp — RadioLib wrapper with C API (extern "C" boundary) - main.cpp — Arduino entry point All files pass pre-commit (prettier, markdownlint, YAML check).
