ADR-081: Implement 5-layer adaptive CSI mesh firmware kernel ( #404 )
...
* ADR-081: adaptive CSI mesh firmware kernel + scaffolding
Introduces a 5-layer firmware kernel that reframes the existing ESP32
modules as components of a chipset-agnostic architecture and authorizes
adaptive control + a compact feature-state stream as the default upstream.
Layers:
L1 Radio Abstraction Layer — rv_radio_ops_t vtable + ESP32 binding
L2 Adaptive Controller — fast/medium/slow loops (200ms/1s/30s)
L3 Mesh Sensing Plane — anchor/observer/relay/coordinator (spec)
L4 On-device Feature Extr. — rv_feature_state_t (magic 0xC5110006)
L5 Rust handoff — feature_state default; debug raw gated
Files:
docs/adr/ADR-081-adaptive-csi-mesh-firmware-kernel.md (new)
firmware/esp32-csi-node/main/rv_radio_ops.h (new)
firmware/esp32-csi-node/main/rv_radio_ops_esp32.c (new)

CHANGELOG.md (Unreleased)
Default policy is conservative: enable_channel_switch and
enable_role_change are off, so behavior matches today's firmware
unless an operator opts in via menuconfig. The pure
adaptive_controller_decide() is exposed for offline unit tests.
Reuses (does not rewrite): csi_collector, edge_processing (ADR-039),
swarm_bridge (ADR-066), secure_tdm (ADR-032), wasm_runtime (ADR-040).
* 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)

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);

* 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
* Add test_rv_mesh to host-test .gitignore
Fixes an untracked-file warning from the repo stop-hook: the compiled
binary was built by make but the .gitignore update was missed in
8dfb031 . No source changes.
* Fix implicit decl of emit_feature_state in adaptive_controller
fast_loop_cb calls emit_feature_state() at line 224, but the static
definition is at line 256. GCC treats the implicit declaration as
non-static, then the real static definition conflicts, and
-Werror=all promotes both to hard build errors.
Add a forward declaration above the first use. Unblocks ESP32-S3
firmware build and all QEMU matrix jobs.

fix(firmware): defensive node_id capture prevents runtime clobber ( #390 )
...
Users on multi-node ESP32 deployments have been reporting for months
that their provisioned `node_id` reverts to the Kconfig default of `1`
in UDP frames and the `csi_collector` init log, despite boot showing:
nvs_config: NVS override: node_id=4
main: ESP32-S3 CSI Node (ADR-018) - Node ID: 4
csi_collector: CSI collection initialized (node_id=1, channel=11)
See #232 , #375 , #385 , #386 , #390 . The root memory-corruption path for
the `g_nvs_config.node_id` byte has not been definitively isolated
(does not reproduce on my attached ESP32-S3 running current source
and the v0.6.0 release binary), but the UDP frame header can be made
tamper-proof regardless:
1. `csi_collector_init()` now captures `g_nvs_config.node_id` into a
module-local `static uint8_t s_node_id` at init time.
2. `csi_serialize_frame()` reads `buf[4]` from `s_node_id`, not from
the global - so any later corruption of `g_nvs_config` cannot
affect outgoing CSI frames.
3. All other consumers (`edge_processing.c` x3, `wasm_runtime.c`,
`display_ui.c`, `main.c swarm_bridge_init`) now go through a new
`csi_collector_get_node_id()` accessor instead of reading the
global directly.
4. A canary at end-of-init logs `WARN` if `g_nvs_config.node_id`
already diverges from the captured value - this will pinpoint
the corruption path if it happens on a user's device.
Hardware validation on attached ESP32-S3 (COM8):
- NVS loads node_id=2
- Boot log: `main: ... Node ID: 2`
- NEW log: `csi_collector: Captured node_id=2 at init (defensive
copy for #232/#375/#385/#390)`
- Init log: `csi_collector: CSI collection initialized (node_id=2)`
- UDP frame byte[4] = 2 (verified via socket sniffer, 15/15 packets)
This is defense in depth - it shields the UDP frame from whatever
upstream bug is clobbering the struct. When a user hits the original
bug, the canary WARN will help isolate the root cause.

feat: ESP32 CSI MAC address filtering with NVS/Kconfig support ( #101 )
...
* feat: add MAC address filter for ESP32 CSI collection
In multi-AP environments, CSI frames from different access points get
mixed together, corrupting the sensing signal. Add transmitter MAC
filtering so only frames from a specified AP are processed.
Implementation:
- csi_collector: filter in wifi_csi_callback by comparing info->mac
against configured MAC; log transmitter MAC in periodic debug output
- csi_collector_set_filter_mac(): runtime API to enable/disable filter
- Kconfig: CSI_FILTER_MAC option (format "AA:BB:CC:DD:EE:FF")
- NVS: "filter_mac" 6-byte blob overrides Kconfig at runtime
- nvs_config: parse Kconfig MAC string at boot, load NVS override
- main: apply filter from config after csi_collector_init()
When no filter is configured (default), behavior is unchanged —
all transmitter MACs are accepted for backward compatibility.
Fixes #98

feat: ADR-029/031 TDM sensing protocol, channel hopping, and NVS config
...
Implement the hardware and firmware portions of RuvSense (ADR-029) and
RuView (ADR-031) for multistatic WiFi sensing:
Rust (wifi-densepose-hardware):
- TdmSchedule: uniform slot assignments with configurable cycle period,
guard intervals, and processing window (default 4-node 20 Hz)
- TdmCoordinator: manages sensing cycles, tracks per-slot completion,
cumulative clock drift compensation (±10 ppm over 50 ms = 0.5 us)
- SyncBeacon: 16-byte wire format for cycle synchronization with
drift correction offsets
- TdmSlotCompleted event for aggregator notification
- 18 unit tests + 4 doctests, all passing
Firmware (C, ESP32):
- Channel-hop table in csi_collector.c (s_hop_channels, configurable
via csi_collector_set_hop_table)
- Timer-driven channel hopping via esp_timer at dwell intervals
- NDP frame injection stub via esp_wifi_80211_tx()
- Backward-compatible: hop_count=1 disables hopping entirely
- NVS config extension: hop_count, chan_list, dwell_ms, tdm_slot,
tdm_node_count with bounds validation and Kconfig fallback defaults

Esp32CsiParser, prints per-frame summary (node, seq, rssi, amp)
- UDP aggregator module with per-node sequence tracking and drop detection
- CsiFrame bridge to detection pipeline (amplitude/phase/SNR conversion)
- Python ESP32 binary parser with UDP reader
- Presence detection confirmed: motion score 10/10 from live CSI variance
Hardware verified: ESP32-S3-DevKitC-1 (CP2102, MAC 3C:0F:02:EC:C2:28),
