ADR-081: implement Layers 1/2/4 end-to-end + host tests + QEMU hooks
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.
New files:
firmware/esp32-csi-node/main/adaptive_controller_decide.c (pure policy)
firmware/esp32-csi-node/main/rv_radio_ops_mock.c (QEMU binding)
firmware/esp32-csi-node/tests/host/Makefile (host tests)
firmware/esp32-csi-node/tests/host/test_adaptive_controller.c

firmware/esp32-csi-node/tests/host/esp_err.h (shim)
firmware/esp32-csi-node/tests/host/.gitignore
Modified:
adaptive_controller.c — includes pure decide.c; emit_feature_state()
wired into fast loop (200 ms = 5 Hz)
rv_radio_ops_esp32.c — get_health() fills pkt_yield + send_fail
csi_collector.{c,h} — pkt_yield/send_fail accessors (ADR-081 L1)
rv_feature_state.h — packed size corrected to 60 bytes
(was incorrectly 80 in initial commit)
main.c — mock binding registered under mock CSI
CMakeLists.txt — rv_radio_ops_mock.c under CSI_MOCK_ENABLED
scripts/validate_qemu_output.py — 3 new ADR-081 checks (17/18/19)
docs/adr/ADR-081-*.md — status → Accepted (partial);
implementation-status matrix; measured
benchmarks (decide 3.2 ns, CRC32 614 ns);
bandwidth 300 B/s @ 5 Hz (99.7% vs raw);

CHANGELOG.md — artifact-level entries
Tests (host, gcc -O2 -std=c11):
test_adaptive_controller: 18/18 pass, decide() = 3.2 ns/call
test_rv_feature_state: 15/15 pass, CRC32(56 B) = 614 ns/pkt, 87 MB/s

IEEE CRC32 known vectors verified
Deferred (tracked in ADR-081 roadmap Phase 3/4):
Layer 3 mesh-plane message types, role-assignment FSM, Rust-side mirror
trait in crates/wifi-densepose-hardware/src/radio_ops.rs.

slower for bit-by-bit CRC and broadly comparable for the decide

function after inlining.
