Keep TCXO warm during owned dual-profile retunes, batch modulation setup, and enable guarded fast RX with buffered 8 MHz SPI on XIAO S3 WIO and Indicator LoRa. Preserve lifecycle invalidation, packet guards, rollback, and existing scheduling budgets. Add reliable sequence-scoped USB lab transport, native regression coverage, bounded channel and preamble diagnostics, and byte-exact measurement records including failed experiments and qualification limits.
