Stage STM32 preference prefixes and checked footers in one atomic image, reject declared tails that encounter premature EOF, and share the typed CLI rollback helper. Use the proven Wio Mini code-layout flags on Wio E5 and Tiny Relay without changing features or memory boundaries. All four STM32 targets and RAK4631 Full pass at the full 1.18.0.1 release version length.
Deduplicate validation and preserve the published preference bytes and transactional saves. Correct Ikoka Handheld Companion flash bounds and document QSPI Room migration. Qualify STM32 and RAK4631 at the full 1.18.0.1 release version length.
Adapt the optional onboard-radio probe for RAK3401 and RAK4631 cores using the external RAK13302 image. Preserve SPI1 radio ownership, external FEM startup, and ordinary RAK4631 primary-radio operation.
Probe before boot voltage protection, bound missing-chip waits, release temporary pads, and confirm cold sleep without waking the chip. Add sanitizer-backed host regression tests and CI coverage.
Provide canonical Full recipes for Waveshare S3 LR1121 and Wio Tracker L2 while retaining directly buildable USB and BLE compatibility recipes. Cover hardware inheritance, menu selection, and exact Full mappings in the release profile tests.
Bring in Wio Tracker L2 Pro, RAK3401/TrackerV2 RS232 recipes and explicit FEM-on defaults. Keep qualified runtime FEM ownership and GPS semantics; retain old V4 target aliases and Bash build entry points. Pin the upstream RadioLib 7.8.1 release exactly instead of an open-ended dependency range.
Integrate upstream 1.18.0, delayed direct ACK forwarding, zero-scope routing, Waveshare LR1121 and dynamic WiFi variants. Preserve fork chemistry-aware power management and bounded multi-interface UI; retain retry/dedup safety while adding upstream ACK delay. Qualify LR1121 band power and HP-only Morse handling with native regressions.
Preserve observer discovery when forwarding is disabled while honoring hidden-node settings. Keep GPS power ownership paired and incorporate upstream GPS diagnostics.
