From 5a7f431b0e4f2d5864a522146b07c1702e7797e2 Mon Sep 17 00:00:00 2001 From: rUv Date: Mon, 20 Apr 2026 10:38:23 -0400 Subject: [PATCH] ADR-081: Implement 5-layer adaptive CSI mesh firmware kernel (#404) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * 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) firmware/esp32-csi-node/main/rv_feature_state.{h,c} (new) firmware/esp32-csi-node/main/adaptive_controller.{h,c} (new) firmware/esp32-csi-node/main/main.c (wire L1+L2) firmware/esp32-csi-node/main/CMakeLists.txt (add 4 sources) firmware/esp32-csi-node/main/Kconfig.projbuild (controller knobs) 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.

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.

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.

The primary flash command was already correct. - **`provision.py` silent NVS wipe** (#391) — The script replaces the entire `csi_cfg` NVS namespace on every run, so partial invocations were silently erasing WiFi credentials and causing `Retrying WiFi connection (10/10)` in the field. Now refuses to run without `--ssid`, `--password`, and `--target-ip` unless `--force-partial` is passed. `--force-partial` prints a warning listing which keys will be wiped. diff --git a/docs/adr/ADR-081-adaptive-csi-mesh-firmware-kernel.md b/docs/adr/ADR-081-adaptive-csi-mesh-firmware-kernel.md new file mode 100644 index 00000000..3b3afda1 --- /dev/null +++ b/docs/adr/ADR-081-adaptive-csi-mesh-firmware-kernel.md @@ -0,0 +1,503 @@ +# ADR-081: Adaptive CSI Mesh Firmware Kernel + +| Field | Value | +|-------------|-----------------------------------------------------------------------| +| **Status** | Accepted — Layers 1/2/3/4/5 implemented and host-tested; mesh RX path and Ed25519 signing tracked as Phase 3.5 polish | +| **Date** | 2026-04-19 | +| **Authors** | ruv | +| **Depends** | ADR-018, ADR-028, ADR-029, ADR-031, ADR-032, ADR-039, ADR-066, ADR-073 | + +## Context + +RuView's firmware grew bottom-up. ADR-018 defined a binary CSI frame, ADR-029 +added channel hopping and TDM, ADR-039 added a tiered edge-intelligence +pipeline, ADR-040 added programmable WASM modules, ADR-060 added per-node +channel and MAC overrides, ADR-066 added a swarm bridge to a coordinator, and +ADR-073 added multifrequency mesh scanning. Each one was a sound local +decision. Together they produced a firmware that works on ESP32-S3 but is +**implicitly coupled** to that chipset through `csi_collector.c` calling +`esp_wifi_*` directly and through hard-coded assumptions about the WiFi driver +callback shape. + +This is a problem for three reasons: + +1. **Portability.** Espressif exposes CSI through an official driver API. On + locked Broadcom and Cypress chips, projects like Nexmon achieve the same + thing by patching the firmware blob — but only for specific chip and + firmware build combinations. Future RuView nodes will likely span both + models plus eventually a custom silicon path. Today, none of the modules + above can be reused unchanged on any non-ESP32 chip. + +2. **Adaptivity.** The current firmware reacts to configuration, not to + conditions. Channel hop intervals, edge tier, vitals cadence, top-K + subcarriers, fall threshold, and power duty are all read from NVS at boot + and never revisited. There is no closed-loop control: if a channel becomes + congested, if motion spikes, if inter-node coherence drops, or if the + environment is stable enough to coast at lower cadence, nothing changes + onboard. The adaptive classifier in `wifi-densepose-sensing-server` does + adapt — but only on the host side, after the data has already traversed the + network at fixed rate. + +3. **Mesh as an afterthought.** ADR-029 wired in a `TdmCoordinator` and ADR-066 + added a swarm bridge to a Cognitum Seed, but there is no first-class node + role enumeration (anchor / observer / fusion-relay / coordinator), no + role-assignment protocol, no `FEATURE_DELTA` message type, no + coordinator-driven channel plan, and no automatic role re-election when a + node drops. Multi-node deployments today are stitched together by manual + per-node NVS provisioning. + +The hard truth is that the firmware hack — getting raw CSI off a radio — is +not the moat. The moat is **adaptive control, multi-node fusion, compact +state encoding, persistent memory, and contrastive reasoning on top of the +radio layer**.

Each `rv_feature_state_t` represents the most recent state of +all three; mode field tells the receiver which window dominates this +update. + +`rv_feature_state_t` does not replace ADR-039's `edge_vitals_pkt_t` +(0xC5110002) or ADR-063's `edge_fused_vitals_pkt_t` (0xC5110004). Those +remain the wire format for vitals-specific consumers. `rv_feature_state_t` +is the **default upstream payload** for the sensing pipeline; vitals +packets are now an alternate emission mode for backward compatibility. + +### Layer 5 — Rust handoff + +The Rust side sees only two streams from a node: + +1. **`feature_state` stream** — `rv_feature_state_t`, default-on, 1–10 Hz. +2. **`debug_csi_frame` stream** — ADR-018 raw frames (magic 0xC5110001), + default-off, opt-in via NVS or `CHANNEL_PLAN`. Used for calibration, + debugging, training-set capture. + +The Rust handoff is mirrored as a trait in +`crates/wifi-densepose-hardware/src/radio_ops.rs` so test harnesses (and +eventually the Rust-side controller for centralized coordinator nodes) can +swap radio backends without touching `wifi-densepose-signal`, +`wifi-densepose-ruvector`, `wifi-densepose-train`, or +`wifi-densepose-mat`. Rust-side mirror trait is **out of scope for the +firmware-only PR** that ships this ADR; tracked as Phase 4 follow-up. + +## State Machine + +``` +BOOT → SELF_TEST → RADIO_INIT → TIME_SYNC → CALIBRATION → SENSE_IDLE + ↓ ↑ + SENSE_ACTIVE + ↓ + ALERT + ↓ + DEGRADED +``` + +Transitions: + +- **CALIBRATION** on boot, on role change, on sustained inter-node + disagreement. +- **SENSE_ACTIVE** when motion or anomaly score crosses threshold. +- **DEGRADED** when packet yield, sync quality, or memory pressure drops + below threshold; falls back to ADR-039 Tier-0 raw passthrough as the + last-resort survivable mode. + +## Data budgets + +| Stream | Default rate | Notes | +|-------------------------|-----------------------------|----------------------------------------------| +| Raw capture (internal) | 50–200 pps per observer | Stays on-device unless debug stream enabled | +| `rv_feature_state_t` | 1–10 Hz per node | Default upstream | +| `ANOMALY_ALERT` | event-driven | Burst-bounded | +| Debug ADR-018 raw CSI | 0 (off by default) | Burst-only via `CHANNEL_PLAN` debug flag | + +ADR-039 measured raw CSI at ~5 KB/frame and ~100 KB/s per node.
