From d53e29506ebd8c82ad152bef6d4ec0aed15d886a Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 19 Apr 2026 03:43:08 +0000 Subject: [PATCH] ADR-081: implement Layers 1/2/4 end-to-end + host tests + QEMU hooks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Turns the ADR-081 scaffolding into a working adaptive CSI mesh kernel: Layer 1 radio abstraction has an ESP32 binding and a mock binding; Layer 2 adaptive controller runs on FreeRTOS timers; Layer 4 feature-state packet is emitted at 5 Hz by default, replacing raw ADR-018 CSI as the default upstream.
