- Mesh, Dispatcher, Packet, packet pool and the core headers rebuilt from Arduino MeshCore's text; ZephCore changes re-applied, each fenced `// ZEPHCORE:` (diff vs upstream: 4540 -> 1147 lines) - upstream header layout; MainBoard gains handleCommand/loop and the other upstream members; RNG::nextInt back in Utils.cpp - packet logging moved to the roles' log hooks (helpers/PacketLog.h) - zero-hop direct ACKs deduplicated and length-checked as upstream - RadioIncludes.h -> src/, LoRaConfig.h -> helpers/ - .editorconfig: shared files keep upstream formatting Verified: 10 role builds, per-function disassembly review, bench DM/ACK regression (T1000-E, Wio L1, XIAO S3 on 1.17.4) incl. via live repeater.
