ADR-081: Layer 3 mesh plane + Rust mirror trait — all 5 layers landed
Fully implements the remaining deferred pieces of the adaptive CSI mesh
firmware kernel. All 5 layers (Radio Abstraction, Adaptive Controller,
Mesh Sensing Plane, On-device Feature Extraction, Rust handoff) are
now implemented and host-tested end-to-end.
Layer 3 — Mesh Sensing Plane (firmware/esp32-csi-node/main/rv_mesh.{h,c}):
* 4 node roles: Unassigned / Anchor / Observer / FusionRelay / Coordinator
* 7 message types: TIME_SYNC, ROLE_ASSIGN, CHANNEL_PLAN,
CALIBRATION_START, FEATURE_DELTA, HEALTH, ANOMALY_ALERT
* 3 auth classes: None / HMAC-SHA256-session / Ed25519-batch
* Payload types: rv_node_status_t (28 B), rv_anomaly_alert_t (28 B),
rv_time_sync_t (16 B), rv_role_assign_t (16 B),
rv_channel_plan_t (24 B), rv_calibration_start_t (20 B)
* 16-byte envelope + payload + IEEE CRC32 trailer
* Pure rv_mesh_encode()/rv_mesh_decode() plus typed convenience encoders
* rv_mesh_send_health() + rv_mesh_send_anomaly() helpers
Controller wiring (adaptive_controller.c):
* Slow loop (30 s default) now emits HEALTH
* apply_decision() emits ANOMALY_ALERT on transitions to ALERT /
DEGRADED
* Role + mesh epoch tracked in module state; epoch bumps on role
change
Layer 5 — Rust mirror (crates/wifi-densepose-hardware/src/radio_ops.rs):
* RadioOps trait mirrors rv_radio_ops_t vtable
* MockRadio backend for offline tests
* MeshHeader / NodeStatus / AnomalyAlert types mirror rv_mesh.h
* Byte-identical IEEE CRC32 (poly 0xEDB88320) verified against
firmware test vectors (0xCBF43926 for "123456789")
* decode_mesh / decode_node_status / decode_anomaly_alert / encode_health
* 8 unit tests, including mesh_constants_match_firmware which asserts
MESH_MAGIC/VERSION/HEADER_SIZE/MAX_PAYLOAD match rv_mesh.h
byte-for-byte
* Exported from lib.rs
* signal/ruvector/train/mat crates untouched — satisfies ADR-081
portability acceptance test
Tests (all passing):
test_adaptive_controller: 18/18 (C, decide() 3.2 ns/call)
test_rv_feature_state: 15/15 (C, CRC32 87 MB/s)
test_rv_mesh: 27/27 (C, roundtrip 1.0 µs)
radio_ops::tests (Rust): 8/8
--- total: 68/68 assertions green ---
Docs:
* ADR-081 status flipped to Accepted
* Implementation-status matrix updated; L3 + Rust mirror both
marked Implemented
* Benchmarks table extended with rv_mesh encode+decode roundtrip
* Verification section updated with cargo test invocation
* CHANGELOG: two new entries for L3 mesh plane + Rust mirror
Remaining follow-ups (Phase 3.5 polish, not blocking):
* Mesh RX path (UDP listener + dispatch) on the firmware
* Ed25519 signing for CHANNEL_PLAN / CALIBRATION_START
* Hardware validation on COM7

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/test_rv_feature_state.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);
verification section
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
sizeof(rv_feature_state_t) == 60 asserted
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.
