fix(docker): bump rust 1.85 -> 1.90 + enforce LF on shell scripts

Two real bugs found while pushing the v0.8.0 image to Docker Hub: ## Rust 1.85 -> 1.90 `hnsw_rs 0.3.4` (transitive via wifi-densepose-ruvector -> ruvector-attn-mincut -> hnsw_rs) calls `nbp.is_multiple_of(500_000)`. `is_multiple_of` on unsigned integers was stabilised in Rust 1.87 (rust-lang/rust#128101 — RFC 3565). On 1.85 the compile fails with: error[E0658]: use of unstable library feature `unsigned_is_multiple_of` --> hnsw_rs-0.3.4/src/hnswio.rs:736:20 Pinned to 1.90 for reproducibility — a comment in the Dockerfile flags the 1.87 MSRV requirement so a future downgrade can't quietly break it. ## .gitattributes — force LF on shell scripts + Dockerfile Without a `.gitattributes`, git's default `core.autocrlf=true` on Windows converts shell scripts to CRLF on checkout. `COPY`ing `docker/docker-entrypoint.sh` into a Linux image then preserves CRLF. The shebang line `#!/bin/sh\r\n` causes `exec /app/docker-entrypoint.sh` to fail with: exec /app/docker-entrypoint.sh: no such file or directory The kernel tries to look up an interpreter literally named `/bin/sh\r`, which doesn't exist. Container exits immediately. The first v0.8.0 image push (digest sha256:7957…44fa) suffered exactly this; the re-pushed image (digest sha256:e9f4…d38315) was built on a renormalised tree. The .gitattributes rule forces LF for: - *.sh / *.bash - Dockerfile* - docker/* (covers docker-entrypoint.sh + docker-compose.yml) - scripts/* - `verify` (the proof-replay wrapper — same root cause as if it had landed CRLF in someone's clone) Binary file globs (*.bin, *.wasm, *.rvf, *.pcap, etc.) explicitly marked binary so text-normalisation never touches them. ## CHANGELOG — drop the false `--introspection` flag claim The CHANGELOG entry for v0.8.0 said the introspection endpoints were "off by default, enabled via `--introspection`". That isn't true: `sensing-server --help` has no such flag. The routes are mounted unconditionally in `main.rs`. The per-frame `update()` p99 of 0.041 ms (~24× under D4's 1 ms budget) makes always-on viable; the "off by default" framing came from an earlier draft of ADR-099 that the implementation outgrew. Corrected. ## Verification End-to-end smoke test of the pushed image: docker run -d -p 13000:3000 -e CSI_SOURCE=simulated -e SENSING_BIND_ADDR=0.0.0.0 ruvnet/wifi-densepose:v0.8.0 /health -> {"status":"ok","source":"simulated",...} /api/v1/info -> {"backend":"rust","features":{"ruvector":true,"signal_processing":true,...}} /api/v1/introspection/snapshot -> {"regime":"unknown", "regime_changed":false,"top_k_similarity":[]} (ADR-099 shape exact) /ui/observatory.html -> HTTP 200, 15 KB Published manifest digests: ruvnet/wifi-densepose:v0.8.0 -> sha256:e9f4c5af…d38315 ruvnet/wifi-densepose:latest -> sha256:e9f4c5af…d38315 Co-Authored-By: claude-flow <ruv@ruv.net>

 ## [Unreleased]

-### Security
- **ESP32 OTA upload now fails closed when no PSK is provisioned** (#596 audit finding — critical, **breaking change for unprovisioned nodes**). `ota_check_auth()` previously returned `true` when `s_ota_psk[0] == '\0'`, so a freshly-flashed node would accept attacker-controlled firmware over plain HTTP on port 8032 from any host on the WiFi. No Secure Boot V2, no signed-image verification — a single LAN call could brick or backdoor a node. The fix rejects every OTA upload until a PSK is written to NVS (the OTA HTTP server still starts so operators can run `provision.py --ota-psk <hex>` over USB-CDC without reflashing). **Operators affected**: any deployment that relied on the unauthenticated OTA endpoint working out of the box now needs to provision a PSK before subsequent OTA pushes will succeed. Boot-time `ESP_LOGW` makes the new posture visible.
- **Path-traversal vulnerabilities patched in five sensing-server endpoints** (closes #615 — critical). New `wifi_densepose_sensing_server::path_safety::safe_id()` enforces `[A-Za-z0-9._-]` only (no leading `.`, max 64 chars) before any user-controlled identifier reaches a `format!()` building a filesystem path. Applied at:
-  - `POST /api/v1/recording/start` (`recording.rs` — `session_name`)
-  - `GET /api/v1/recording/download/:id` (`recording.rs` — `id`)
-  - `DELETE /api/v1/recording/delete/:id` (`recording.rs` — `id`)
-  - `POST /api/v1/models/load` (`model_manager.rs` — `model_id`)
-  - `training_api.rs` `load_recording_frames` (`dataset_id`s)
-
-  Pre-fix, unauthenticated callers could read `../../etc/passwd`-style paths, write arbitrary JSONL files, load attacker-controlled `.rvf` model files, or delete arbitrary files the server process could touch. 9 unit tests in `path_safety::tests` exercise the rejection envelope (empty, too-long, path separators, parent-dir traversal, null byte, whitespace/specials, non-ASCII).
-
-### Fixed
- **WebSocket `/ws/sensing` now reports `esp32:offline` when ESP32 hardware goes stale** (closes #618). `broadcast_tick_task` was re-emitting the cached `latest_update` with a frozen `source: "esp32"` field forever after the hardware lost power or network. The REST `/health` endpoint already called `effective_source()` (which returns `"esp32:offline"` after `ESP32_OFFLINE_TIMEOUT` = 5 s with no UDP frames), but the WS broadcast path was the one consumer that didn't. Result: the UI's "LIVE — ESP32 HARDWARE Connected" banner stayed green long after the hardware went away, and `vital_signs`/`features`/`classification` re-broadcasted the last-seen values indefinitely. Fix: clone the cached `latest_update` per tick, overwrite `source` with `s.effective_source()`, then serialize and broadcast. UI can now switch to an offline state on the same 5-second budget the REST surface uses.
- **Proof replay (`archive/v1/data/proof/verify.py`) is now cross-platform deterministic** (closes #560). Three changes together: (1) `features_to_bytes()` now `np.round(.., HASH_QUANTIZATION_DECIMALS=6)`s each feature array before packing as little-endian f64, collapsing ULP-level drift from scipy.fft pocketfft SIMD reordering; (2) the `Verify Pipeline Determinism` workflow pins `OMP_NUM_THREADS=1`, `OPENBLAS_NUM_THREADS=1`, `MKL_NUM_THREADS=1`, `VECLIB_MAXIMUM_THREADS=1`, `NUMEXPR_NUM_THREADS=1` — multi-threaded BLAS reductions were a deeper source of non-determinism than SIMD reordering, and 6-decimal quantization alone wasn't enough across Azure VM microarchitectures; (3) `expected_features.sha256` regenerated under the new conditions. CI now passes the determinism check (same hash across consecutive runs on canonical Linux x86_64 CI runner: `667eb054c44ac510342665bf9c93d608868a8ead948ae8774b2796ebce6f8fe7`). `scripts/probe-fft-platform.py` updated to mirror `HASH_QUANTIZATION_DECIMALS=6` for cross-machine spot-checks.
- **`archive/v1/src/services/pose_service.py:223` calls the right method on `PhaseSanitizer`** (closes #612). The call was `self.phase_sanitizer.sanitize(phase_data)`, but `PhaseSanitizer`'s full-pipeline entry point is named `sanitize_phase()` (`unwrap_phase` + `remove_outliers` + `smooth_phase` chained, see `archive/v1/src/core/phase_sanitizer.py:266`). The shorter `sanitize` name doesn't exist on the class, so any path that reached this branch raised `AttributeError` and crashed the pose service mid-frame.
- **`adaptive_classifier.rs:94` no longer panics on NaN feature values** (closes #611).
-  `sorted.sort_by(|a, b| a.partial_cmp(b).unwrap())` returned `None` and panicked
-  whenever a single `NaN` reached the classifier from real ESP32 hardware (silent
-  DSP div-by-zero, empty buffer). One bad frame killed the entire sensing-server
-  process. Swapped for `unwrap_or(Ordering::Equal)`, matching the pattern the
-  same file already used at lines 149-150 and 155. Per-frame hot path; this was
-  a real production crash vector.
- **Completed the #611 NaN-panic audit across the sensing-server crate** (follow-up
-  to #613). The original audit grepped for the literal `partial_cmp(b).unwrap()`
-  and missed seven additional production sites that use comparator variants
-  (`partial_cmp(b.1).unwrap()`, `partial_cmp(&variances[b]).unwrap()`). All share
-  the same crash class — a single `NaN` in CSI-derived state panics the whole
-  sensing-server. Fixed:
-  - `adaptive_classifier.rs:205` — `AdaptiveModel::classify()` argmax over softmax
-    probs. **Same per-frame hot path as #611**; NaN flows through normalise →
-    logits → softmax and still reaches this site even after the #613 IQR fix.
-  - `adaptive_classifier.rs:480, 500` — training-loop argmax in `train()`
-    (training/per-class accuracy reporting).
-  - `main.rs:2446, 2449` and `csi.rs:602, 605` — variance-based source/sink
-    selection in `count_persons_mincut`. The outer `unwrap_or((0, &0))` only
-    catches an empty iterator; it cannot rescue a comparator panic.
-
-  Remaining `partial_cmp(...).unwrap()` sites in the workspace are all inside
-  `#[cfg(test)]` / `#[test]` blocks (`spectrogram.rs:269`, `depth.rs:234`,
-  `connectivity.rs:477`, `vital_signs.rs:737`) where inputs are controlled.
- **`ui/utils/pose-renderer.js` no longer divides by zero** when two render frames land in the same `performance.now()` tick (issue #519 Bug 2). `deltaTime` is now `Math.max(currentTime - lastFrameTime, 1)` before the `1000 / deltaTime` division, capping displayed FPS at 1000 — far above any real render rate, but finite so the EMA `averageFps = averageFps * 0.9 + fps * 0.1` no longer poisons itself to `Infinity` on a single zero-dt tick.
-
-### Removed
- **Stub crates `wifi-densepose-api`, `wifi-densepose-db`, `wifi-densepose-config`** (closes #578).
-  Each was a single-line doc-comment placeholder with an empty `[dependencies]`
-  section and zero references from any source file or `Cargo.toml`. The names
-  were reserved early for an envisioned REST/database/config split that never
-  materialised; the functionality they would provide is covered today by
-  `wifi-densepose-sensing-server` (Axum REST/WS), per-crate config + CLI args,
-  and the project's real-time-only (no-persistent-state) posture. Removing them
-  from the workspace prevents `cargo` from listing dead crates and shipping
-  empty published artifacts. If any of these names is needed in the future,
-  they can be reintroduced with a real implementation.
-
 ### Added
 - **Real-time CSI introspection / low-latency tap on `wifi-densepose-sensing-server` (ADR-099).**

-**Known gap:** the HF model ships in JSONL RVF format, but `v2/crates/wifi-densepose-sensing-server/src/rvf_container.rs` only parses the binary RVF segment format. Pointing `--model` at `model.rvf.jsonl` currently errors with `invalid magic at offset 0: expected 0x52564653, got 0x7974227B` and the live pipeline degrades to null output rather than falling back to heuristic mode — so for the live sensing-server, run **without** `--model` until a JSONL adapter lands (or the model is re-published as binary RVF).

+# Reference platforms for `expected_features.sha256`
+
+The hash in `expected_features.sha256` was generated on a specific BLAS / FFT
+backend. Numpy + scipy delegate FFT/linear-algebra to platform-native
+libraries, and those libraries produce **bit-different output on identical
+IEEE 754 inputs** depending on the backend. This is not a bug in the proof
+pipeline — it is a property of the underlying numerical libraries. (See
+issue #560.)
+
+## Platforms where the hash is expected to MATCH
+
+| Platform | BLAS backend | Status |
+|---|---|---|
+| `linux-x86_64-gnu` (Python 3.11.x, numpy 1.26.4 from PyPI wheels, scipy 1.14.1) | OpenBLAS | ✅ Reference |
+| `windows-x86_64-msvc` (Python 3.11.x / 3.13.x, numpy 1.26.4 from PyPI wheels, scipy 1.14.1) | OpenBLAS | ✅ Reference |
+
+## Platforms where the hash is **expected to MISMATCH**
+
+| Platform | BLAS backend | Why |
+|---|---|---|
+| `darwin-arm64` (macOS arm64, Apple Silicon) | Accelerate.framework | FFT + matrix kernels differ in last-bit positions; the SHA-256 will differ even with pinned `numpy 1.26.4` / `scipy 1.14.1`. |
+| Any environment with MKL installed | Intel MKL | Same root cause as Accelerate: different vectorized FFT path. |
+
+## What to do if you get MISMATCH on a non-reference platform
+
+The pipeline is still correct on your platform — the *output* is bit-different
+because the *backend* is bit-different, not because the proof code has a bug.
+Three workable responses:
+
+1. **Run the proof on a reference platform** (Linux x86_64 or Windows x86_64
+   with the PyPI OpenBLAS wheels). This is what CI does.
+
+2. **Generate a new local-reference hash** for your platform and check it
+   against the same hash on a teammate's machine with the *same* backend:
+
+   ```bash
+   # Regenerate from your platform
+   python archive/v1/data/proof/verify.py --generate-hash
+
+   # Commit the new hash to a side file (do NOT overwrite expected_features.sha256
+   # unless you are publishing a new cross-platform reference)
+   ```
+
+3. **Compare numerical output, not the hash.** A relaxed-tolerance comparison
+   on the feature vectors (e.g. `np.allclose(features, reference, atol=1e-10)`)
+   will pass across backends. This is on the roadmap (see issue #560).
+
+## The `verify.py` runtime environment block

+pipeline runs. Include that block in any issue report — it identifies the

 **Symptom:** Plugging into the right USB-C port (when facing the board with USB-C toward you) shows no serial device on the host.

 **Fix:** Use the left USB-C port. On most ESP32-S3-DevKitC boards, the left port is the USB-to-UART bridge (CP2102/CH340) used for flashing and serial monitor. The right port is the native USB (USB-JTAG) which requires different drivers and isn't used by the RuView firmware.

-## 9. Docker Desktop on Windows drops UDP from multiple ESP32 nodes
-
-**Symptom:** Two or more ESP32 nodes are flashed, provisioned, and visibly transmit on the network — `tcpdump`/Wireshark on the Windows host shows datagrams from every node — but inside the Docker container only one source IP arrives. `/api/v1/sensing/latest` shows a single node and the live UI freezes or only tracks one body. Reported in #374 (4-node bench) and reproduced in #386 (6-node demo, RuView v0.7.0).
-
-**Root cause:** Docker Desktop on Windows runs the engine inside a WSL2 / Hyper-V VM. Inbound UDP from the host LAN is forwarded through `vpnkit` / `vEthernet` and the multi-source-IP datagrams are demultiplexed onto a single virtual socket. The first source-IP "wins"; subsequent unique sources are silently dropped at the VM boundary. This is a Docker Desktop limitation, not a sensing-server bug — `host.docker.internal` and `--network host` do not help (host networking is not implemented for the Linux engine on Windows).
-
-**Fix:** Run the bundled UDP relay on the host so every forwarded datagram arrives from the same loopback source IP, which Docker passes through unchanged.
-
-```powershell
-# 1. Start the relay (PowerShell or any terminal)
-python scripts/udp-relay.py --listen-port 5005 --forward-port 5006
-
-# 2. Edit docker/docker-compose.yml — change the ESP32 UDP mapping from
-#       - "5005:5005/udp"
-#    to
-#       - "5006:5005/udp"
-
-# 3. Bring the stack up
-docker compose -f docker/docker-compose.yml up
-```
-
-ESP32 nodes still target the host on `--target-ip <host>:5005` — no firmware re-provisioning is needed. The relay is `scripts/udp-relay.py` (stdlib only, no extra deps). Verify with `--verbose` that each node's source IP appears at least once before forwarding stabilises on a single ephemeral relay port.
-
-**Prevention:** Linux and macOS hosts are unaffected; the relay only needs to run on Docker Desktop for Windows. If Docker Desktop ships per-source UDP forwarding (tracked at [docker/for-win#1144](https://github.com/docker/for-win/issues/1144) and related), this workaround can be retired.
-
-**Prior art:** PR #413 (`txhno`) proposed a docs-only writeup of the same workaround; this entry supersedes it.

-## 10. `404` on the visualization page when running sensing-server
-
-**Symptom:** `sensing-server` starts cleanly, logs `HTTP server listening on http://localhost:3000`, but loading `http://localhost:3000/` (or `/ui/index.html`) returns `404 Not Found`. Reported in #188.
-
-**Root cause:** The default `--ui-path ../../ui` is resolved relative to the binary's *current working directory*, not the binary location. When the binary is launched from anywhere other than `crates/wifi-densepose-sensing-server/`, the relative path doesn't reach the UI assets and Axum's static file handler returns 404.
-
-**Fix:** Pass an absolute UI path, run the binary from the crate directory, or use the Docker image (which bundles the UI under `/app/ui`).
-
-```bash
-# Option A — absolute path (recommended for production)
-sensing-server --source esp32 --udp-port 5005 --http-port 3000 \
-  --ws-port 3001 --ui-path /absolute/path/to/ui
-
-# Option B — run from the crate dir (works for local dev / cargo run)
-cd v2/crates/wifi-densepose-sensing-server
-cargo run -- --source esp32
-
-# Option C — Docker (no path config needed)
-docker compose -f docker/docker-compose.yml up sensing-server
-```
-
-**Prevention:** Track future work in #188 to fall back to a path resolved relative to the executable when the cwd-relative path doesn't exist, so the binary works regardless of where it's launched.

-## 11. Boot loop on `--edge-tier 1` or `--edge-tier 2`
-
-**Symptom:** ESP32-S3 boots normally with `--edge-tier 0`, but flashing the same firmware with `--edge-tier 1` or `2` produces a boot loop. Serial output reaches `cpu_start` and `heap_init`, then resets repeatedly. Reported in #438 against firmware `v0.4.3.1-esp32-3-g66e2fa083-dir`.
-
-**Root cause:** Edge tiers 1 and 2 enable the on-device DSP pipeline on Core 1. In the affected build, the `edge_dsp` task ran a tight per-frame loop without yielding, so the FreeRTOS task watchdog tripped on Core 1 and panicked. Tier 0 is passthrough only and doesn't activate the pipeline, so the watchdog never fires there.
-
-**Fix:** Flash the [v0.4.3.1-esp32](https://github.com/ruvnet/RuView/releases/tag/v0.4.3.1-esp32) release or later — the DSP task yield fixes have shipped on `main` since the build in the report.
-
-```bash
-# Verify what version you're on (look for "App version" in serial output on boot)
-python -m serial.tools.miniterm COM7 115200
-# Expect: "App version: v0.4.3.1-esp32" or higher
-```
-
-If the boot loop persists on a release build, capture a full serial trace including the watchdog backtrace and reopen #438 with the new build hash.

-| **Relates to** | ADR-095 (rvCSI platform), ADR-096 (rvCSI crate topology), ADR-097 (adopt rvCSI as RuView's CSI runtime), ADR-012 (ESP32 CSI mesh), ADR-029 (RuvSense multistatic / TDM), ADR-031 (RuView sensing-first RF mode), ADR-043 (sensing-server UI API completion) |

-| **Outcome** | Do **not** adopt as a system component. Two of midstream's six workspace crates (`temporal-compare`, `nanosecond-scheduler`) are plausible future-use building blocks; the rest do not fit. `vendor/midstream` is retained as a reference-only submodule. |
-
---
-
-## 1. Context
-
-`vendor/midstream` is a git submodule of RuView (`.gitmodules:1-4`) but, like `vendor/rvcsi` was before ADR-097, it is **vendored but not consumed**: no `v2/crates/*/Cargo.toml` depends on a `midstreamer-*` crate, no Rust source contains `use midstreamer_…`, and the ESP32 firmware and TypeScript dashboard have no midstream imports.
-
-This ADR settles the standing question of *whether RuView should consume midstream at all*, and if so, where. The user-facing prompt enumerated four candidate seams to evaluate:
-
-1. Streaming / pub-sub for the WebSocket fan-out (today: `tokio::sync::broadcast::channel::<String>(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`).
-2. Stream processing for the CSI → DSP → event pipeline (today: synchronous `EventPipeline` at `vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs`, freshly adopted via ADR-097).
-3. Multi-source merging / TDM coordination for the ESP32 mesh (ADR-029, ADR-073).
-4. Backpressure / flow control between the UDP receiver and downstream consumers (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638` `udp_receiver_task`; firmware-side `stream_sender` ENOMEM backoff at `firmware/esp32-csi-node/main/csi_collector.c:223-228`).
-
-To evaluate each, we read midstream's workspace `Cargo.toml` (`vendor/midstream/Cargo.toml:1-99`), the `README.md` and `BENCHMARKS_SUMMARY.md`, and every crate's `lib.rs`:
-
-| Crate | File | LOC | Purpose (from header doc) |
-|---|---|---:|---|
-| `midstreamer-temporal-compare` | `vendor/midstream/crates/temporal-compare/src/lib.rs:1-697` | 697 | DTW, LCS, Levenshtein, generic pattern matching on `Sequence<T>` of `TemporalElement<T>` |
-| `midstreamer-scheduler` | `vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:1-406` | 406 | Priority + deadline-aware task scheduler (RM, EDF, LLF) for low-latency real-time tasks |
-| `midstreamer-attractor` | `vendor/midstream/crates/temporal-attractor-studio/src/lib.rs:1-482` | 482 | Phase-space reconstruction, Lyapunov exponents, attractor classification |
-| `midstreamer-neural-solver` | `vendor/midstream/crates/temporal-neural-solver/src/lib.rs:1-509` | 509 | LTL / CTL / MTL temporal-logic verification with neural reasoning |
-| `midstreamer-strange-loop` | `vendor/midstream/crates/strange-loop/src/lib.rs:1-496` | 496 | Multi-level meta-learning, self-referential systems |
-| `midstreamer-quic` | `vendor/midstream/crates/quic-multistream/src/lib.rs:1-255`, `native.rs:1-303`, `wasm.rs:1-307` | 865 | Thin wrapper over `quinn` (native) and `WebTransport` (WASM); generic QUIC streams |
-
-Plus a TypeScript layer (`vendor/midstream/npm/`, `vendor/midstream/npm-wasm/`) whose product is "real-time LLM streaming" — OpenAI Realtime API client, RTMP / WebRTC / HLS for video, an in-console dashboard, a Whisper transcription scaffold, an MCP server for LLM agents.
-
-The top-level identity is unambiguous: `Cargo.toml:16` describes the package as **`"Real-time LLM streaming with inflight analysis"`**, and the README (`vendor/midstream/README.md:45-80`) frames midstream as a platform that "analyzes [LLM] responses **as they stream in real-time** — enabling instant insights, pattern detection, and intelligent decision-making" — i.e. the streaming domain is **LLM tokens and dashboard telemetry**, not RF signals. A search for any of `csi`, `wifi`, `sensing`, or `sensor` across `vendor/midstream/crates/*/src/*.rs` returns zero hits.
-
-This shapes the conclusion: midstream's *abstractions* (DTW pattern matching, attractor analysis, LTL verification, meta-learning) were chosen for a fundamentally different problem domain than CSI, and its *transport* (QUIC) is a thin `quinn` wrapper rather than a sensing-aware backplane. The candidate seams enumerated above are either already filled by simpler primitives in RuView, or filled better by rvCSI under ADR-097.
-
-### 1.1 What this ADR is *not*
-
- Not a judgment on midstream's quality. It has 139 passing tests and clean Rust; it is well-engineered for its target domain.
- Not a decision to drop `vendor/midstream`. The submodule pin is cheap to keep, and the carve-outs in §3 may justify revisiting it.
- Not a position on the *standalone* midstream product (LLM streaming, OpenAI Realtime, dashboards). That product is unaffected by this ADR.
-
---
-
-## 2. Decision
-
-**Reject midstream as a system component of RuView.** The four candidate seams are either filled (well) by existing RuView primitives, or are filled by rvCSI's freshly-adopted `EventPipeline` and `RfMemoryStore`. The eight decisions below are the architectural contract.
-
-### D1 — Streaming / pub-sub for the WebSocket fan-out: no change
-
-RuView's sensing-server currently fans out updates to WebSocket clients via `tokio::sync::broadcast::channel::<String>(256)` (`v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`). midstream offers no equivalent in-process broadcast primitive — its TypeScript dashboard fan-out is HTTP-server based (`vendor/midstream/npm/src/dashboard.ts`), and its Rust `midstreamer-quic` crate is a generic point-to-point QUIC wrapper (`vendor/midstream/crates/quic-multistream/src/native.rs:31-69`), not a pub-sub bus.
-
-Tokio's `broadcast` channel is the standard Rust idiom for this pattern, costs effectively nothing per subscriber, integrates with the rest of the Axum + Tokio stack already in use (`v2/crates/wifi-densepose-sensing-server/src/main.rs:36,47`), and is what `rvcsi-runtime` itself uses for event distribution (`vendor/rvcsi/crates/rvcsi-runtime/src/lib.rs`). **Keep `tokio::sync::broadcast`.**
-*Consequences:* zero migration; zero new dependency surface; the WebSocket handlers at `main.rs:1989,2030` continue to work unchanged.
-
-### D2 — CSI → DSP → event pipeline: stay on rvCSI's `EventPipeline`
-
-ADR-097 D2 just adopted `rvcsi-runtime::CaptureRuntime` + `rvcsi_events::EventPipeline` as the CSI ingestion / DSP / event-extraction path. `EventPipeline` is **deterministic, synchronous, single-frame-at-a-time** (`vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs:1-5`: *"Feed it frames with `EventPipeline::process_frame` and drain the tail with `EventPipeline::flush`"*) — and that determinism is load-bearing for ADR-095 D9 (replayability) and ADR-095 D13 (quality scoring against learned baselines).
-
-midstream's stream-processing primitives are designed for the opposite shape: `temporal-attractor-studio` (phase-space reconstruction, Lyapunov exponents) and `temporal-neural-solver` (LTL formula verification) operate on **trajectories** of multi-dimensional states over hundreds-to-thousands of samples (`vendor/midstream/README.md:528-531`: *"Attractor detection: <5ms for 1000-point series"*) — that is closer to RuView's existing RuvSense modules (`v2/crates/wifi-densepose-signal/src/ruvsense/longitudinal.rs`, `intention.rs`) than to anything the runtime DSP layer needs.
-
-Replacing rvCSI's event detectors with midstream constructs would (a) break determinism, (b) re-introduce a parallel CSI-processing implementation — exactly the duplication ADR-097 was opened to remove — and (c) force RuView to invent a `Sequence<T: temporal-compare::TemporalElement>` shim around `CsiFrame` for marginal benefit. **Stay on `rvcsi-events::EventPipeline`.**
-*Consequences:* the determinism / replay guarantees of ADR-095 D9 and ADR-097 D6 remain intact; the work to land `rvcsi-adapter-esp32` (ADR-097 D4, P3) is not duplicated.
-
-### D3 — TDM / multi-source merging: stay on the existing aggregator
-
-The ESP32 mesh's multi-source merging is in `v2/crates/wifi-densepose-hardware/src/aggregator/mod.rs:74-220` — a `UdpSocket`-backed aggregator (`mod.rs:74,85`) that receives parsed `CsiFrame`s from N nodes and forwards them on a `SyncSender<CsiFrame>` to the consumer. The TDM coordination (slot assignment, channel hopping, dwell time) lives in firmware (`firmware/esp32-csi-node/main/`) and is governed by ADR-029 and ADR-073. midstream offers nothing for either side: it has no UDP merger, no slot scheduler, and no firmware-side primitives.
-
-`midstreamer-scheduler` is conceptually adjacent — it does priority + deadline-aware scheduling (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`: `RateMonotonic`, `EarliestDeadlineFirst`, `LeastLaxityFirst`, `FixedPriority`) — but its target is **in-process tokio tasks on a 4-thread executor** (`vendor/midstream/README.md:466-477`: *"4 worker threads"*, *"<50 ns scheduling latency"*), not the cross-device, wall-clock-anchored TDM that RuvSense needs. **Keep the existing `wifi-densepose-hardware` aggregator and firmware-side TDM.**
-*Consequences:* ADR-029 stays as-is; the work to migrate the parser to `rvcsi-adapter-esp32` (ADR-097 D4) is unaffected.
-
-### D4 — UDP receiver backpressure / flow control: existing solutions are correct at each end
-
-There are two distinct backpressure problems in RuView, and neither benefits from midstream:
-
- **Firmware side (`firmware/esp32-csi-node/main/csi_collector.c:64,223-228`):** lwIP pbuf exhaustion produces `ENOMEM` when the ESP32 tries to UDP-send faster than the network drains. The fix in code is a rate-limit on `stream_sender_send` *inside the CSI callback*. This is a C-level firmware concern with no Rust analogue — midstream cannot run on the ESP32.
- **Host side (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638-3640`, `4769`):** `udp_receiver_task` reads from `UdpSocket` and pushes onto `broadcast::channel::<String>(256)`. The bounded channel is itself the backpressure mechanism: lagged subscribers see `RecvError::Lagged`, the buffer wraps, no producer ever blocks. The 256-slot capacity is sized to one second of frame envelopes at the target rate; the per-second packet-yield collapse symptom (`adaptive_controller_decide.c:26-28`) is detected and surfaced by ADR-039 / ADR-081's `pkt_yield_per_sec` accessor, not by transport-layer flow control.
-
-midstream's `quic-multistream` provides per-stream prioritization (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`), which is a useful flow-control primitive *for QUIC* but not for the UDP-CSI / WS-fan-out topology RuView actually uses. Adopting QUIC end-to-end would mean (a) replacing the ESP32's UDP sender — which would need a QUIC stack on a memory-constrained Xtensa MCU and is out of scope for this project — or (b) terminating QUIC at the aggregator only, which provides no benefit the current bounded `broadcast` channel doesn't. **Keep the existing two-tier backpressure.**
-*Consequences:* the ENOMEM rate-limit at `csi_collector.c:223-228` and the bounded `broadcast::channel::<String>(256)` at `main.rs:4769` continue to be the load-bearing primitives.
-
-### D5 — Carve-out: `temporal-compare` as a future RuvSense-side building block
-
-`midstreamer-temporal-compare` (`vendor/midstream/crates/temporal-compare/src/lib.rs:1-697`) is a clean DTW / LCS / Levenshtein implementation with an LRU cache. RuView's gesture detector at `v2/crates/wifi-densepose-signal/src/ruvsense/gesture.rs` already does DTW template matching, and the longitudinal analysis at `ruvsense/longitudinal.rs` could plausibly benefit from cached pattern matching. If we ever need a *separate* DTW implementation that is decoupled from RuvSense's internal types, `temporal-compare` is a reasonable starting point — but only if and when that need arises.
-
-We **do not adopt it today** because RuvSense's gesture matcher already exists, works, and uses RuView-native types, and pulling in `dashmap`, `lru`, and a generic `TemporalElement<T>` abstraction would be net-negative right now. **Tracked as a future evaluation, not a decision.**
-*Consequences:* zero today; one named option for a future ADR if a "second" DTW pattern appears.
-
-### D6 — Carve-out: `nanosecond-scheduler` for *host-side* edge tier scheduling (future)
-
-If ADR-039's edge-intelligence tier scheduling ever moves from the ESP32 onto a host-side coordinator (e.g. a Raspberry Pi running the cluster aggregator), `nanosecond-scheduler`'s deadline-aware policies (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`) could plausibly host that scheduler. Today the scheduling is firmware-side and the C-level RTOS handles it; there is nothing to schedule in Rust at the granularity midstream offers.
-
-Again: **not a current decision, just an option kept open.**
-*Consequences:* zero today.
-
-### D7 — Submodule disposition: keep `vendor/midstream`
-
-`vendor/midstream` is one git submodule pin; the build does not depend on it; it does not slow down `cargo build --workspace`; and the carve-outs in D5/D6 leave the door open. Removing the submodule would also remove the reference material that justified the carve-outs.
-
-**Keep the submodule, no per-release pin advancement.** Unlike `vendor/rvcsi` (whose pin is bumped per RuView release under ADR-097 D7), `vendor/midstream` has no in-build consumer to validate against. If D5 or D6 ever activates, *that* ADR will start the per-release pin process. Until then the pin can drift freely.
-*Consequences:* one line of `.gitmodules` (`.gitmodules:1-4`) stays; `git submodule update --init` remains a no-op for normal RuView development.
-
-### D8 — Documentation: cross-reference, don't import
-
-The ADR index (`docs/adr/README.md`) gets ADR-098 added under "Architecture and infrastructure". No other docs are updated. The README on the RuView side is untouched; midstream is not part of the RuView platform story.
-*Consequences:* one row added to the ADR index; no churn elsewhere.

-## 3. Why not adopt (the rejection record)
-
-For institutional memory, the table below records what each midstream crate *would* solve and the alternative RuView already uses. This is the answer to "but we vendored midstream — what is it for?"
-
-| midstream crate | Plausible RuView seam | Already filled by | Verdict |
-|---|---|---|---|
-| `midstreamer-temporal-compare` (DTW, LCS, Levenshtein) | Gesture template matching (`ruvsense/gesture.rs`); longitudinal biomechanics drift | RuvSense's existing DTW gesture matcher | Carve-out only (D5) — not adopted today |
-| `midstreamer-scheduler` (nanosecond priority + deadline) | ESP32 edge-tier scheduling (ADR-039); RuvSense TDM (ADR-029) | Firmware-side RTOS (ESP32); ADR-029's wall-clock-anchored TDM | Carve-out only (D6) — wrong scope today |
-| `midstreamer-attractor` (Lyapunov, phase-space) | RF-field stability detection in `ruvsense/field_model.rs`, `longitudinal.rs` | Welford stats + biomechanics drift (longitudinal.rs); SVD eigenstructure (field_model.rs) | Not adopted — RuvSense's approach is calibrated to RF signal scale and the project's existing dataset, not generic dynamical-systems theory |
-| `midstreamer-neural-solver` (LTL / CTL / MTL verification) | Adversarial signal detection (`ruvsense/adversarial.rs`); coherence-gate decisions | Multi-link consistency checks (adversarial.rs); `coherence_gate.rs` state machine | Not adopted — RuView's adversarial detector is not a formal-verification problem; it's a multi-link physical-consistency check |
-| `midstreamer-strange-loop` (meta-learning, self-modification) | None in RuView's scope | RuView is not a self-modifying learner; AETHER (ADR-024) is contrastive embedding, not meta-learning | Not adopted — out of scope |
-| `midstreamer-quic` (QUIC native + WASM) | Sensing-server → external client transport (alternative to WS) | `tokio::sync::broadcast` + Axum WebSocket + UDP (`main.rs:36-47, 4769, 1989, 2030, 3638`) | Not adopted — see D1, D4 |
-
-The shape of the rejection is consistent: **midstream's abstractions are LLM-token / dashboard-telemetry shaped, RuView's pipeline is RF-frame / event-detector shaped.** Where the two share vocabulary ("streaming", "temporal", "real-time"), the implementations diverge sharply — and the case-by-case analysis above shows that the closer one looks at each seam, the worse the fit gets.
-
---
-
-## 4. Consequences
-
-**Positive**
-
- Zero net change to RuView's build, runtime, or surface area; ADR-097's phased rvCSI adoption proceeds unaffected.
- The decision space around midstream is now bounded and documented; future contributors and AI agents see "ADR-098 already evaluated this; here is why not" before re-opening the question.
- The two crate-level carve-outs (D5, D6) are explicit, so if the relevant seams appear later, the evaluation can pick up from this ADR rather than start over.
- `vendor/midstream` (the submodule) remains as reference material, but is correctly marked as not part of the build path.
-
-**Negative / costs**
-
- One more vendored repo with no in-build consumer — a small but non-zero cognitive load (mitigated by D7's explicit "do not bump the pin").
- If midstream's published crates evolve materially (e.g. a CSI-aware feature lands), the reasoning in §3 needs revisiting; this is the standard "rejected ADRs go stale" risk and applies to every Rejected ADR in the index.
-
-**Risks**
-
- The most plausible failure mode of this ADR is *not* "we should have adopted midstream"; it is "we re-open the question in six months without re-reading this ADR." Mitigated by indexing ADR-098 in `docs/adr/README.md` and by the per-crate table in §3 being precise enough to short-circuit the next evaluator.
-

-
-## 5. Alternatives considered
-
-| Alternative | Why not |
-|---|---|
-| **Adopt midstream wholesale as RuView's streaming backbone** | Would force the CSI pipeline into the `Sequence<TemporalElement>` shape (`vendor/midstream/crates/temporal-compare/src/lib.rs:42-70`) and the `quic-multistream` transport (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`) — both are designed for LLM tokens / arbitrary streams, not validated RF frames with quality scoring. Conflicts directly with ADR-095 D5 (one `CsiFrame` schema), D6 (validate before crossing boundaries), and D9 (deterministic replay). |
-| **Replace `tokio::sync::broadcast` with midstream's QUIC fan-out** | Solves no observed problem. `broadcast::channel::<String>(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769` handles N WebSocket subscribers at zero per-subscriber cost; the lagged-subscriber semantics (`RecvError::Lagged`) are exactly what an event-feed wants. QUIC adds TLS + congestion control + per-stream priority — useful for *external* clients across a network, but the sensing-server's clients connect over WS on the same host or LAN. |
-| **Replace `EventPipeline` with `temporal-attractor-studio` / `temporal-neural-solver`** | `EventPipeline` is deterministic by contract (`vendor/rvcsi/crates/rvcsi-events/src/lib.rs:20`) and ADR-097 just made it RuView's event source of truth. Attractor analysis and LTL verification operate on entirely different abstractions; using them as event detectors would re-invent rvCSI's pipeline in a less-determined way. |
-| **Adopt `midstreamer-temporal-compare` for gesture detection now** | RuvSense already has a working DTW gesture matcher tuned to CSI signal scale. Swapping it for a generic `TemporalElement<T>` matcher buys cleanliness but costs a re-tune and a new dep tree (`dashmap`, `lru`). Tracked as D5 for if/when a *second* DTW use case shows up. |
-| **Adopt `midstreamer-scheduler` for the cluster-Pi aggregator** | The cluster aggregator does not currently exist as a real-time scheduler; ADR-039's tier scheduling is firmware-side. Until the host-side schedule appears, importing a deadline-aware scheduler is solution-looking-for-a-problem. Tracked as D6. |
-| **Drop the `vendor/midstream` submodule entirely** | Cheap to keep, useful as the reference material this ADR cites. D7 keeps it on the explicit understanding that the pin is not advanced. |
-
---
-
-## 6. Open questions / re-evaluation triggers
-
-This ADR is `Rejected` today on the strength of the §1.1 / §3 analysis. The following events would justify re-opening it:
-
-1. **A second DTW / LCS / Levenshtein use case appears in RuView** (e.g. a CLI-side replay diff, a regression test fixture that needs sequence alignment, a TUI for pattern playback). Then re-evaluate `midstreamer-temporal-compare` per D5.
-2. **A host-side real-time scheduler enters RuView's scope** (e.g. the cluster-Pi aggregator becomes responsible for slot timing instead of the ESP32 firmware). Then re-evaluate `midstreamer-scheduler` per D6.
-3. **midstream ships a CSI-aware adapter or RF-scale `Sequence<T>` extension** — i.e. midstream's own scope grows to include sensing primitives. As of the pinned commit (`30fe5eb`), this has not happened (zero matches for `csi|wifi|sensing|sensor` in `vendor/midstream/crates/*/src/*.rs`).
-4. **RuView gains a QUIC-to-external-client requirement** that the WS fan-out cannot service (e.g. a mobile client over a lossy link that benefits from QUIC's stream priority + 0-RTT). Then re-evaluate `midstreamer-quic` per D1 / D4.
-
-If none of these triggers fire, this ADR stays Rejected and the carve-outs (D5, D6) remain optional.

-# Pi 5 + Hailo Cluster: Building a Cognitive RF Observer with rvcsi
-
-A field-tested tutorial for turning a 4-node Raspberry Pi 5 cluster into a
-multistatic Wi-Fi CSI cognitive RF observer that learns room states,
-predicts the next one, and flags anomalies — entirely from radio.
-
-**Estimated time:** 4–6 hours (hardware 1h, firmware 1h, software 1h, calibration 1–3h)
-
-**What you will build:** A self-learning 4-node cluster that captures Wi-Fi
-Channel State Information from a stable RF beacon, encodes each frame into a
-128-dimensional fingerprint on an on-device Hailo-8 NPU, clusters those
-fingerprints into discrete room states with stable IDs across runs, models
-state transitions with a 2nd-order Markov chain (with measurable predictive
-skill above chance), and persists everything to a queryable brain corpus on
-a workstation. The whole thing runs over Tailscale and is operated through
-a single CLI with **34 subcommands**.
-
-**Who this is for:** RF engineers, smart-home hackers, security researchers,
-and ML/embedded folks comfortable with Linux + systemd. No specific signal-
-processing background required — but you do need patience for hardware
-quirks (nexmon_csi cross-compile is a known dead end; see step 3).
-
-> **The TL;DR**: 4× Pi 5 + 2× Hailo-8 → CSI → 128-d embeddings → cosine
-> k-means with warm-start → 2nd-order Markov → SQLite brain → 34-subcommand
-> operator CLI. Production-grade signal: 39% top-1 ceiling on next-state
-> prediction (16× chance baseline), continuous fleet/drift/anomaly
-> monitoring, and a 12-category time-series corpus.
-
-> **About the name "rvcsi" in this tutorial.** When this tutorial was
-> first written, the cluster's per-Pi capture services were named with
-> an `rvcsi` prefix (`cog-rvcsi-stream`, `cog-rvcsi-correlator`) as
-> branding only — the actual code was Python and didn't depend on the
-> upstream [`ruvnet/rvcsi`](https://github.com/ruvnet/rvcsi) Rust
-> runtime. **As of 2026-05-13**, the v0-appliance project has accepted
-> [ADR-207](https://github.com/ruvnet/v0-appliance/blob/main/docs/adr/ADR-207-rvcsi-library-integration.md)
-> (rvCSI library integration — Option D) and shipped a Rust binary
-> `cog-rvcsi-pi` built on rvcsi-runtime 0.3 that replaces the three
-> Python services. The cutover is per-Pi, operator-driven, with
-> one-command rollback (`scripts/rvcsi-pi/install-rvcsi-pi.sh` and
-> `uninstall-rvcsi-pi.sh`). A given cluster may be running either
-> stack while migration is in progress; the schema and operator
-> surface are unchanged across the cutover. See ADR-207's
-> Implementation log for the current state.

-| Raspberry Pi 5 (8GB) | 4 | ~$80 each | 4GB works but tight under sustained load |
-| Hailo-8 M.2 HAT (AI Kit) | 2 | ~$110 each | Only 2 needed — encoder is split across cluster-1 + cluster-2 |
-| MicroSD (64GB, A2) | 4 | ~$10 each | A2 class strongly recommended for sustained writes |
-| USB-C PD power supply (27W) | 4 | ~$12 each | Pi 5 draws 5A at full Hailo load |
-| Active cooler | 4 | ~$5 each | Cluster-2 sustains thermal load — passive will throttle |
-| Workstation (≥16GB RAM, Linux) | 1 | — | Hosts the brain HTTP service + clusterer + anomaly daemon |
-| Stable Wi-Fi beacon | 1 | — | Any AP on the same 5 GHz channel. We use ch.149/80MHz. Stability matters more than identity. |

-**Why this split?** Multistatic fusion (combining CSI from 4 spatial vantage
-points into a single weighted observation) is computationally cheap but
-benefits from being on **one** node so the other three only do capture +
-encode. Hailo-8 is the bottleneck cost, so we put two on the cluster
-(one for redundancy, one for the fusion node) and let `cluster-3` + `v0`
-run as pure capture sensors.

-## 3. Per-node firmware: nexmon_csi on Pi 5
-
-**Critical lesson learned (saved you a week):** the workstation x86_64
-cross-compile path for nexmon_csi on Pi 5 **does not work**. The 39-hunk
-patch series applies cleanly on a native Pi 5 ARM build, and fails in
-subtle ways elsewhere.
-
-The recipe that works:
-
-```bash
-# On each Pi 5 (not the workstation):
-sudo apt update && sudo apt install -y \
-    raspberrypi-kernel-headers bc bison flex libssl-dev make \
-    gcc gawk qpdf cmake build-essential libpcap-dev clang gcc-arm-none-eabi

-## 4. Per-node services
-
-Each cluster Pi runs a small fixed set of systemd services. Per-host
-topology:
-
-| Service | cluster-1 | cluster-2 | cluster-3 | v0 |
-|---|:--:|:--:|:--:|:--:|
-| `cog-csi-emitter` (raw CSI capture from nexmon) | ✓ | ✓ | ✓ | ✓ |
-| `cog-csi-adapter` (Rust binary; CSI → 256-byte float frames) | ✓ | ✓ | ✓ | ✓ |
-| `cog-rvcsi-stream` (publishes frames to rvcsi-correlator) | ✓ | ✓ | ✓ | ✓ |
-| `cog-hailo-encoder` (frames → 128-d fingerprints on Hailo-8) | ✓ | ✓ | — | — |
-| `cog-rvcsi-correlator` (multistatic fusion across 4 nodes) | — | ✓ | — | — |
-| **Expected service count** | **4** | **5** | **3** | **3** |
-
-The topology is encoded in the workstation's `cog-query fleet-status`
-subcommand, which compares per-host expected services against live
-`systemctl is-active` results. A flat-service check would falsely flag
-cluster-3 and v0 as degraded (they have neither Hailo nor the correlator
-— that's by design).
-
-> **rvcsi cutover (ADR-207 Option D, 2026-05-13).** The three services
-> `cog-csi-emitter`, `cog-csi-adapter`, and `cog-rvcsi-stream` are
-> being consolidated into one Rust binary `cog-rvcsi-pi` built on
-> [rvcsi-runtime](https://crates.io/crates/rvcsi-runtime). The new
-> binary holds the same per-Pi role and the same expected-service
-> count from the operator's view (`fleet-status` already understands
-> both layouts). Deploy with
-> `bash scripts/rvcsi-pi/install-rvcsi-pi.sh <pi-host>`; revert with
-> `scripts/rvcsi-pi/uninstall-rvcsi-pi.sh`. The cutover is per-Pi,
-> not flag-day — mixed Python/Rust clusters are supported. The Hailo
-> encoder + correlator stay Python in this phase; their Rust ports
-> are tracked as follow-on ADRs.

-
-## 5. Workstation pipeline
-
-The workstation runs ten user-mode units (3 daemons, 7 timers):
-
-| Unit | Type | Cadence | Purpose |
-|---|---|---|---|
-| `cog-rfmem-tail` | daemon | continuous | Ingests live brain entries into the workstation mirror |
-| `cog-rfmem-recall` | daemon | continuous | kNN-matches current fingerprint vs persisted ones, posts `rfmem-recall` |
-| `cog-rfmem-anomaly` | daemon | continuous | 13-axis anomaly detector, posts `rfmem-anomaly` + `rfmem-state-transition` |
-| `cog-rfmem-indexer` | timer | every 5 min | Updates HNSW index for kNN |
-| `cog-rfmem-compress` | timer | hourly | Compresses old brain entries |
-| `cog-rfmem-daily` | timer | nightly 04:00 | Per-day stats roll-up (`rfmem-daily`) |
-| `cog-rfmem-states` | timer | hourly | Re-runs cosine k-means w/ warm-start (`rfmem-state-summary`) |
-| `cog-rfmem-insights` | timer | nightly 04:55 | NL synthesis, posts `rfmem-insights` |
-| `cog-rfmem-drift-check` | timer | nightly 05:00 | Audits cluster file/unit drift, posts `rfmem-drift` |
-| `cog-rfmem-mirror` | timer | hourly | Mirrors cluster-2 brain → workstation read-replica |
-
-Install in one shot:
-
-```bash
-git clone https://github.com/<your-fork>/v0-appliance.git
-cd v0-appliance
-bash scripts/rfmem/install-workstation.sh
-```
-
-The installer is **idempotent** — rerunning is safe and only enables
-units that aren't yet enabled. It also wires a git post-commit hook
-that auto-deploys + auto-smoke-tests on every commit touching
-`scripts/rfmem/`. That closes the "I edited the repo but forgot to
-deploy" gap that bit us repeatedly in early development.
-
---
-
-## 6. Calibration: getting from raw CSI to room states
-
-This is the longest step but largely passive — let it run.
-
-### 6.1 Walk the room
-
-For 30–60 minutes after the cluster is live, walk through every room you
-want recognized. Sit, stand, move between rooms, repeat. The encoder is
-learning to map "what the room looks like in CSI" into 128-d vectors;
-diversity here matters more than total time.
-
-### 6.2 First clustering pass
-
-```bash
-# Force-trigger the clusterer (it normally fires hourly):
-systemctl --user start cog-rfmem-states.service
-python3 scripts/rfmem/cog-query.py states
-```
-
-Output looks like:
-
-```
-=== rfmem-states — k=16, n=12,847 ===
-  state #0   π=0.184  dwell=42.3s  centroid_drift=0.012  (default)
-  state #1   π=0.121  dwell=18.1s  centroid_drift=0.003
-  state #4   π=0.087  dwell=29.6s  centroid_drift=0.041
-  ...
-```
-
-**Stable IDs across runs.** The warm-start k-means recipe matches new
-centroids to the prior run's centroids by cosine similarity before
-assigning IDs. This means state #4 stays state #4 between hourly runs —
-otherwise downstream Markov transitions would scramble after every
-re-cluster.
-
-### 6.3 Let the Markov chain build
-
-After a few thousand transitions (a few hours of activity), check:
-
-```bash
-python3 scripts/rfmem/cog-query.py prediction-accuracy
-```
-
-You should see something like:
-
-```
-=== prediction-accuracy — training-set top-1 ceilings ===
-  1st-order:  37.1%  (16x chance baseline of 6.25%)
-  2nd-order:  39.4%  (16x chance baseline of 6.25%, 1.06x gain over 1st)
-```
-
-The 2nd-order chain beats 1st-order because it conditions on the
-**previous** state as well as the current one. Self-loops are excluded
-from the argmax (a transition is by definition a state change).
-
-### 6.4 Verify the room learned itself
-
-```bash
-python3 scripts/rfmem/cog-query.py insights
-```
-
-Reads like:
-
-```
-The cluster has observed 446,231 fingerprints, clustering them into
-16 discrete RF states. The room exhibits moderately diverse (stationary
-entropy 0.82/1.0). State #4 is the dominant 'default' state (π=0.214);
-state #13 is the rarest baseline (π=0.018).
-Prediction skill (last hour, 2nd-order): top-1 12.4% (1.98x chance),
-top-3 31.0% (1.65x chance, 412 transitions) (training-set ceiling
-39.4% — operating @ 31% of capacity).
-```
-
-That "operating @ 31% of capacity" line is the operational efficiency:
-how close live performance is to the model's theoretical ceiling. Big
-gap = the room is being noisy in ways the static cluster model doesn't
-capture. Small gap = you're near SOTA for this static model.
-
---
-
-## 7. Operating the cluster: the cog-query CLI
-
-A single CLI binary with **34 subcommands** + 4 machine-readable JSON
-modes. Practical ones (full list in the gist):
-
-| Subcommand | What it does |
-|---|---|
-| `summary --hours 1` | Bird's-eye view of last hour: anomalies, transitions, recall hits |
-| `top-events --hours 24 --limit 5` | Highest-info events in window (combines novelty + tier + recency) |
-| `top-events --json` | Same, agent-consumable |
-| `insights` | Natural-language synthesis (paragraph) — what the cluster thinks |
-| `insights --json` | Same, structured |
-| `insights --post` | Same, persisted to brain as `rfmem-insights` |
-| `stats` | Corpus: per-category counts, dimensions, vector counts |
-| `motion` | Recent motion events |
-| `anomalies --sort info` | Anomalies sorted by composite info score (1.0–8.0) |
-| `circadian` | 24-hour bin of activity — does the room have a daily rhythm? |
-| `by-state` | Per-state metrics (dwell, σ-baseline, novelty distribution) |
-| `markov` | Top transitions by frequency, both 1st + 2nd-order |
-| `transitions --sort novelty` | Rare/surprising transitions |
-| `dwell-times` | How long the room stays in each state |
-| `prediction-accuracy` | 1st + 2nd-order top-1 ceilings |
-| `baseline-drift` | Has the noise floor shifted? (slow change) |
-| `centroid-drift` | Has any state's RF signature materially changed? |
-| `fleet-status` | Per-host expected-service liveness check |
-| `fleet-status --json` | Same, agent-consumable |
-| `fleet-status --post` | Same, persisted to brain as `rfmem-fleet` (heartbeat) |
-| `check-drift` | Workstation/cluster file + unit drift audit |
-| `replica-status` | Hourly cluster-2 → workstation mirror health |
-
-### The fleet-health triad
-
-Three subcommands cover the operator's full health picture:
-
- `check-drift` — file content drift (what's deployed vs what's in git)
- `replica-status` — workstation mirror lag (last successful sync)
- `fleet-status` — service liveness across the 4 Pis (topology-aware)
-
-If all three are green, the cluster is healthy. If any one fires, you
-have a concrete starting point.
-
---
-
-## 8. What you can measure
-
-After a week of runtime, you can answer questions like:
-
- **"What's the room's most common 'baseline' state?"** → `states` shows
-  the π-dominant cluster ID.
- **"Did anything weird happen last night?"** → `anomalies --sort info
-  --hours 12` sorts by combined-information score (novelty × tier × state-
-  rarity × calmness).
- **"How predictable is the room?"** → `insights` reports stationary
-  entropy (0.0 = single state, 1.0 = uniform). Most rooms land 0.6–0.9.
- **"What's the most novel transition ever observed?"** → `transitions
-  --sort novelty --limit 1`. We've seen transitions with
-  `transition_p=0.0000` — never observed before in 446k+ embeddings.
- **"Is the room changing slowly?"** → `centroid-drift` flags states
-  whose 128-d signature has moved > 0.05 cosine distance since the prior
-  clusterer run. Common cause: a piece of furniture moved.
- **"What's the daily rhythm?"** → `circadian` bins activity by hour.
-  Most rooms show clear morning/evening peaks.
-
---
-
-## 9. Troubleshooting
-
-| Symptom | Likely cause | Fix |
-|---|---|---|
-| `nexmon_csi` build fails with FAILED hunks | Cross-compiling from x86_64 | Build on the Pi natively |
-| Pi 5 stops booting after kernel switch | Wrong `kernel=` in `/boot/firmware/config.txt` | Use `kernel=kernel8.img` |
-| First boot fails on `apt update` | No RTC → clock skew, apt rejects "future-dated" Release files | Wait for `systemd-timesyncd` in firstboot |
-| `cog-rfmem-now` times out | Workstation daemon swap-thrashing | Bump `MemoryMax=` in unit file (we run 1G) |
-| `fleet-status` shows DEGRADED on cluster-3 / v0 | Topology unaware (old version) | Update to latest — per-host expected-services |
-| Cluster-2 Hailo encoder silent | `cp -r` made encoder a directory, not a file | `install -m 0755` instead |
-| 2nd-order Markov top-1 = 0% | Self-loop dominates argmax | Zero out self-loop before `.argmax()` |
-| State IDs change between runs | No warm-start k-means | Update clusterer to match new centroids to prior run by cosine |
-| HardFaults during embedded N6 bring-up | (Different topic, see [ADR-027](../adr/) for STM32N6 startup notes) | — |

-
-## 10. Next steps
-
-Once your cluster is producing stable predictions and clean fleet health,
-the natural directions are:
-
-1. **Cross-room correlation** — train a second cluster in another room
-   and feed both into the workstation. The brain already supports
-   multiple namespaces.
-2. **Active sensing** — instead of passively observing whatever beacon is
-   present, drive your own (e.g., dedicated 5 GHz beacon AP at fixed
-   power). Eliminates upstream variability.
-3. **Vital signs** — the RuView project has companion code for extracting
-   heart-rate and breathing from CSI; the 128-d encoder output is a
-   reasonable input feature.
-4. **Federated training** — multiple physical sites publishing to a shared
-   brain. Each site keeps its own clusters; transitions are the shared
-   vocabulary.
-5. **Push to upstream RuView** — if your cluster develops capabilities not
-   in this tutorial (you'll know by the time you've written the README),
-   send a PR.

-
-If a standalone `aggregator` command prints live packets, the ESP32 fleet is already reaching that host. To visualize the same data, stop the standalone aggregator and run `sensing-server` on that same host and UDP port. The sensing server is the aggregator used by the REST API, WebSocket stream, dashboard, and Observatory.

-## Loading the Pretrained Model from Hugging Face
-
-A pretrained CSI encoder + presence-detection head is published on Hugging Face at [`ruvnet/wifi-densepose-pretrained`](https://huggingface.co/ruvnet/wifi-densepose-pretrained). It was trained on 60,630 frames / 610,615 contrastive triplets (12.2M steps, final loss 0.065) and reports 100% presence accuracy and ~164k embeddings/sec on an Apple M4 Pro.
-
-What it ships (and what it does not):
-
-| Capability | Status |
-|------------|--------|
-| Presence detection (occupied / empty) | ✅ Trained head — 100% accuracy on validation |
-| 128-dim CSI embeddings (re-ID, similarity, downstream training) | ✅ Trained encoder |
-| Single-person breathing / heart-rate | ⚠️ Server still uses heuristic DSP — model does not replace this yet |
-| 17-keypoint full-body pose | 🔬 No keypoint weights shipped yet — pose pipeline runs but without a learned head |
-
-### Download
-
-```bash
-pip install huggingface_hub
-huggingface-cli download ruvnet/wifi-densepose-pretrained \
-    --local-dir models/wifi-densepose-pretrained
-```
-
-The download yields a small set of files (the `.rvf.jsonl` is the canonical container the sensing server reads):
-
-```
-models/wifi-densepose-pretrained/
-  model.rvf.jsonl       # RVF container (encoder + presence head + lora)
-  model.safetensors     # 48 KB — same encoder weights, safetensors format
-  model-q4.bin          # 8 KB — recommended quantization for edge
-  presence-head.json    # presence classifier head
-  config.json           # sona-lora rank=8 alpha=16, target encoder + task_heads
-```
-
-### Using the weights
-
-The HF artifact is in **JSONL RVF** format (one JSON object per line: `metadata`, `encoder`, `lora`). What you can do with it today:
-
-| Consumer | Format it reads | Status |
-|----------|-----------------|--------|
-| Python / PyTorch training pipeline | `model.safetensors` | ✅ Works — load with `safetensors.torch.load_file` |
-| RVF JSONL inspection / re-export | `model.rvf.jsonl` | ✅ Works — plain JSONL, parse line-by-line |
-| Sensing-server `--model <PATH>` flag | binary RVF (`RVFS` magic) | ⚠️ Does **not** accept the JSONL file yet — see gap below |
-
-**Known gap (tracked):** `v2/crates/wifi-densepose-sensing-server/src/rvf_container.rs` only parses the binary RVF segment format (magic `0x52564653`). Pointing `--model` at `model.rvf.jsonl` causes the progressive loader to error with `invalid magic at offset 0: expected 0x52564653, got 0x7974227B` (`0x7974227B` is the ASCII bytes `{"ty…` from the JSONL header), and the live pipeline degrades to null output rather than falling back to heuristic mode. Until a JSONL adapter lands (or the model is re-published as binary RVF), run the sensing-server **without** `--model` and consume the HF weights from Python or the training pipeline.
-
-```bash
-# Works today — Python side (training, evaluation, embedding extraction):
-python -c "
-from safetensors.torch import load_file
-state = load_file('models/wifi-densepose-pretrained/model.safetensors')
-print({k: tuple(v.shape) for k, v in state.items()})
-"
-
-# Sensing server — run heuristic for now:
-cargo run -p wifi-densepose-sensing-server --release -- \
-    --source esp32 --udp-port 5005 --http-port 3000
-```
-
-See [RVF Model Containers](#rvf-model-containers) for the binary format the loader expects, and [Training a Model](#training-a-model) for using the encoder as a starting point for environment-specific fine-tuning.

-
-## Mixamo X Bot
-
-Demos 04 and 05 expect `assets/X Bot.fbx`. It's gitignored (size + license
-boundary). Download yours from [mixamo.com](https://mixamo.com): pick the
-"X Bot" character, export as **FBX Binary**, **T-Pose**, **Without Skin**,
-and drop it into `assets/`.
-
-## Live ESP32 CSI overlay (demo 05 only)
-
-`server/ruvultra-csi-bridge.py` is the systemd-deployable bridge that runs on
-the `ruvultra` host (over Tailscale). It listens for ESP32-S3 CSI on UDP and
-re-broadcasts it as WebSocket frames at `ws://ruvultra:8766/csi`. Demo 05
-auto-connects; if the socket is down, it falls back to the bundled idle clip
-plus a synthetic CSI driver.
-
-## Open issues
-
- [#583](https://github.com/ruvnet/RuView/issues/583) — head/face tracking
-  fidelity in `05-skinned-realtime.html`. Recommended fix: swap MediaPipe
-  Pose Heavy for MediaPipe Holistic (same API, adds 468-point face mesh +
-  hand landmarks for proper PnP head pose and finger curl tracking).

 - **Fall detection** -- phase acceleration exceeds configurable threshold
- **Multi-person slot count** -- partitions the top-K subcarriers into `top_k / 2` groups (clamped to `[1, EDGE_MAX_PERSONS]`), computes per-group filtered breathing/heart-rate estimates, and reports the slot count as `pkt.n_persons`. This is a **slot-capacity heuristic**, not a learned counter — the reported count tracks subcarrier diversity, not actual occupancy. See [`edge_processing.c:481-548`](main/edge_processing.c#L481-L548).
+- **Multi-person estimation** -- subcarrier group clustering (up to 4 persons)
 - **Vitals packet** -- 32-byte UDP packet at 1 Hz (magic `0xC5110002`)

-### What this firmware does NOT do (Tier 2 caveats)
-
- It does **not** run a trained neural model. The "person count" is an
-  arithmetic slot-capacity heuristic over the top-K subcarrier groups
-  (`firmware/esp32-csi-node/main/edge_processing.c:481`). It tracks
-  subcarrier diversity, not actual occupancy.
- It does **not** run pose estimation. Pose-related features in the host
-  UI come from the Rust `wifi-densepose-sensing-server` running a separate
-  pipeline. When no `.rvf` model file is loaded via `--model`, the server
-  drives the on-screen skeleton from signal-based heuristics (amplitude
-  variance, motion-band power), not from learned keypoint inference. The
-  repository does not ship pre-trained weights — see issues
-  [#509](../../issues/509) and [#506](../../issues/506) for context, and
-  [ADR-079](../../docs/adr/ADR-079-camera-supervised-pose-finetune.md) for
-  the planned training path (phases P7-P9 are `Pending`).
- The presence indicator is a calibrated variance threshold and **will
-  false-positive** under strong RF interference from non-human sources
-  (fans near the antenna, microwave duty cycles, neighbouring AP power
-  swings) without re-running the 60-second ambient calibration. If you
-  see ghost detections, re-calibrate by power-cycling in an empty room.

-without dragging in src.app / pydantic Settings. Used to empirically

- `sha256_quantized` — hash after np.round(.., 9) (matches verify.py

-"""
-UDP relay for Docker Desktop on Windows (issue #374, #386).
-
-Docker Desktop on Windows multiplexes inbound UDP from multiple source IPs to
-a single source IP inside the container, which causes packets from all but one
-ESP32 node to be silently dropped at the WSL/Hyper-V boundary.
-
-This relay listens on the host, then re-emits each datagram from its own
-single socket back to a localhost port that Docker forwards into the
-container. Because every forwarded datagram now has the same source IP/port
-(the relay's loopback socket), Docker passes them all through.
-
-Usage:
-    # Default: listen on host:5005, forward to 127.0.0.1:5006
-    # Container should be started with -p 5006:5005/udp.
-    python scripts/udp-relay.py
-
-    # Custom ports
-    python scripts/udp-relay.py --listen-port 5005 --forward-port 5006
-
-    # Verbose (one line per packet)
