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.
