From fb2d1afb0ce96e3609402eb5cfe282c9de0ac35b Mon Sep 17 00:00:00 2001 From: ruv Date: Sat, 14 Mar 2026 11:08:59 -0400 Subject: [PATCH] feat(firmware): complete ADR-061 QEMU testing platform (all 9 layers) Fix 9 bugs (LFSR bias, MAC filter init, scenario loop, NVS boundary values), add 7 new files completing Layers 3 (mesh), 4 (GDB), 5 (coverage), 8 (snapshots), 9 (chaos testing), expand CI with fuzz and NVS validation jobs, update README with full platform overview.
