Use compact scalar crypto, reviewed GNSS version parsing and shared CLI reply copies for RAK3401/RAK4631 repeaters. Preserve keys, protocols, commands and configured capacities.
Both Reduced images save 11,580 bytes. SWD measurements on the RAK3401 found scalar-only signing still near 50.9 ms and key exchange near 38 ms. Keep compact field arithmetic off: its extra 4.3 KiB saving adds about a quarter second and delays radio servicing.
Validate Full and Reduced production OTA packages on both boards, focused crypto/GPS/CLI tests, and linked ARM crypto outputs. Include the RAM benchmark harness and scoped results. No live RF packet-loss qualification is claimed.
Remove unrelated ecosystem comparisons and software citations while retaining hardware links, measured model names, and required license notices.
Preserve stock-peer runners and tests in a verified local validation package. Keep shared Companion USB transport in the firmware repository for the raw-radio sweep and OTA seeder, with focused CI coverage. Restore missing hosted documentation links.
Forward --inplace-memory only when explicitly supplied, preserving authenticated layout bounds and the conservative legacy fallback.
Validation: MOTATOOL_TEST_BIN=/home/mesh/git/motatool/target/release/motatool python3 -m unittest test_lora_ota (318 passed). Both new auto-sizing regressions fail against the prior runner.
Add receive-only same-image display, SPI, modem/IQ-cache and scoped-priority experiments with checkpointed collectors. Keep rejected clock-phase correction and elevated-priority experiments out of production.
Publish sanitized timing data, Full Companion/Bluetooth/USB checks and redraw measurements with their limits. Wire the new behavioral checks into CI.
Run DHCP and renewal in a cooperative worker, bound socket commands, and retain SPI ownership until cleanup is safe. Preserve framing deadlines, response ownership and whole-frame replay, including pending-ACK queue pinning.
Budget the worker additively and retain all OTA names with an exact-checked Full-only compact index. Add full-driver, sanitizer, queue, shutdown, storage and memory regression coverage.
