 ## [Unreleased]

+### Community batch (PRs #2100-#2157 by aepod, reviewed and integrated)
+
+Integrated as one set: conflicts resolved, review findings fixed, validated on the integrated branch. Hardware figures cited by the PRs are the author's own live runs on ESP32-S3 nodes and were not independently reproduced here.
+
+- **Security and honest status.** Refuse a routable HTTP bind when API auth is off (#2134). `--privacy-mode` now strips biometrics from REST, WebSocket and recordings, not only MQTT (#2125; the stripped-key list is an exact-match allowlist, so a new biometric field must be added to it). `/api/v1/status` waits for a real frame and unknown `--source` values are rejected (#2126; breaking for `--source macos|linux|windows`). A stale `/sensing/latest` reports `{"status":"stale"}` after 10 s (#2119). Measured stream fps and real WebSocket client counts (#2127). Absent nodes no longer count as one person (#2132). ESP32 frames with zero antennas or subcarriers are dropped (#2118). Dead nodes are evicted on a timer (#2120). Recordings and models stay under `--data-dir` (#2129). Boolean env flags accept 1/0/yes/no/on/off (#2108). Docker UDP ingest posture is explicit (#2107).
+- **CSI pipeline.** The grid gate locks on the majority frame shape and `/health` reports a stalled pipeline (#2157; a partial fix, mixed 192/306 frame shapes still drop frames, so it does not close #1894). Phase is combined across nodes only when they declare a shared reference (#2156). Point-cloud and hardware parsers use the ADR-018 layout and accept more than 256 subcarriers (#2155; the bandwidth rule for counts above 64 is CLAIMED, inferred from the datasheet). Per-node adaptive training from real recordings (#2101, #2103); a run that fell back to the live buffer now reports `degraded: true`. Gaussian decay no longer compounds across calls (#2140).
+- **MediaTek (ADR-266/267).** Legacy and unknown PPDU types in MTC1 (#2112), per-device ingest capped at 64 devices (#2113), a labelled amplitude heuristic and activity index (#2114; CLAIMED, not an occupancy estimate), an MT7981 bridge (#2115), and the OpenWrt WN586X3 patch set and guide (#2116; the vendored CSI patch is BSD-3-Clause-Clear, see `NOTICE`).
+- **MQTT / Home Assistant.** Semantic states wired into the publisher, entities announced only when sourced, persisted client id (#2117). Existing Home Assistant installs keep retained discovery configs for the six removed entities until they are cleared manually.
+- **Provisioning and firmware.** Wi-Fi password kept owner-only and out of argv and `--state` (#2153); state keyed by board MAC (#2152); `--dry-run` and a failed `--reset` leave state intact (#2111); OTA images confirmed by a bounded health check, which means only "reached the network and sent CSI" (#2100, ADR-379).
+- **Ground truth and spatial.** Radar window adapter and auto-labeller with a session-disjoint split and a median count baseline; radar labels carry `evidence: CLAIMED` (#2143, #2144). Node self-survey, check-only (#2145, ADR-381). The `spatial.evidence.v1` export defaults to the CODE proof grade and MEASURED requires a reproducer (#2141, ADR-382). Loopback UDP tee (#2102, ADR-380).
+- **Tooling.** `prove.sh` reports INCOMPLETE instead of PASS when a gate is skipped (#2130); ADR-018 capture scripts (#2131); API token on the ground-truth script (#2104); the UI asks for the API token instead of retrying forever (#2128); macOS redacted-link handling (#2105).
+- **Not included:** #2106 (MacWifi.app, draft) and #2142 (MR60 probe change, needs a captured MR60BHA2 boot log). `v2/data/adaptive_model.json` (41.5% training accuracy) is no longer tracked (#2135).

+**Symptom:** ESP32-S3 node associates with WiFi, LED blinks, but no CSI frames arrive at the server. Node missing from `/api/v1/nodes`.
+
+**Check the server first:** the UDP receiver listens on `127.0.0.1` by default (ADR-296), so a natively run `sensing-server` never hears nodes on your network unless it was started with `--udp-bind 0.0.0.0 --udp-allow <node-ip-or-cidr>` (or `--udp-insecure-lan`). The startup log line for the UDP receiver says `loopback-only` when this is the problem. For Docker, see "Receiving ESP32 frames in Docker" in the [user guide](user-guide.md).

 - Issue [#56](https://github.com/ruvnet/wifi-densepose/issues/56): macOS support request
+
+---
+
+## Amendment 1 (2026-10-01): SSID is also redacted; keep the connected link
+
+**Observed on macOS 27 (M-series Mac, CoreWLAN, unsigned CLI helper).** Without Location Services, `mac_wifi --scan-once` returns `"ssid":""` and `"bssid":"00:00:00:00:00:00"`, while `rssi`, `noise`, `channel` and `tx_rate` are real. The §1 assumption that "SSID + RSSI + channel" survive no longer holds. An unsigned CLI helper never calls `CLLocationManager`, so it never appears in Location Services and cannot be granted access.
+
+Before this amendment, `resolve_bssid` abstained when both identities were blank (to avoid merging unrelated networks), so every macOS scan was dropped and `--source wifi` produced nothing, with no error.
+
+**Change.**
+1. `--scan-once` marks its single sample `"connected": true`. It is always the one connected link, so it cannot collide with another network.
+2. A redacted sample marked `connected` gets a stable, locally administered synthetic BSSID derived from a reserved key plus the channel. The SSID stays empty; none is invented. Unmarked redacted lines still abstain.
+3. `--source auto` that resolves to host WiFi now also binds the UDP receiver, and `wifi_task` yields while the source is a live `esp32`. ESP32 nodes that start after the 2 s boot probe still promote the source, matching the #1004 rule for the simulator.
+4. A missing helper logs one clear error with the build command instead of a warning on every tick.
+
+**Measured (2026-10-01, this change):** `--source wifi` → source `wifi:unnamed`, sensing ticks advance. `--source auto` on a quiet port → `wifi` with `udp_receiver=true`; relaying real ADR-018 frames promoted the source to `esp32`, with all 5 nodes listed.
+
+**Still open:** real BSSID/SSID would need a signed `.app` helper with `NSLocationWhenInUseUsageDescription` that requests authorization. The helper still lives under `archive/v1` with no build step.

+## 11. Status note: P4.5 semantic states on the live publisher (2026-10-02)
+
+Issues [#2085](https://github.com/ruvnet/RuView/issues/2085) and [#2093](https://github.com/ruvnet/RuView/issues/2093) found that discovery announced 20 entities per device while only 6 ever received state, that `presence/state` was published on every CSI frame, and that HA device ids changed on every restart. The FSMs in `crate::semantic` existed but had no caller outside their tests. This note records what is now wired and what is not.
+
+### 11.1 What changed
+
+- **Semantic primitives run on the live path.** `mqtt::planner` holds one `SemanticBus` per node, sampled at 1 Hz (the rate the FSM constants assume). The bus feeds only the MQTT publisher. Matter does not consume it yet, so the "output broadcast channel shared with Matter" in P4.5 is not built.
+- **Announce only what has a source.** Six primitives are announced: `room_active`, `no_movement`, `elderly_inactivity_anomaly`, `someone_sleeping`, `possible_distress` and `fall_risk_elevated`. Four are not: `meeting_in_progress` needs a 1–20 % motion level, but per-node motion is a three-level classification; `bathroom_occupied`, `bed_exit` and `multi_room_transition` need zones, and the broadcast carries none (the §3.12.5 zone file is not implemented). For the same reason `zone_occupancy` (§3.1) and `pose` are not announced: `pose_keypoints` is never populated on the broadcast, and `persons[].keypoints` are synthesized.
+- **Per-entity availability (§3.6).** An announced entity is `online` only while its input exists: vitals while the calibration-gated estimate is published, `fall` while the node sends `edge_vitals`, `motion_energy` and `rssi` while present, and semantic primitives after the 60 s warmup (sleeping and distress also need breathing or heart rate, fall risk needs the fall detector). Otherwise it is `offline` and no state is sent. Transitions publish at once; all availability topics are re-sent every 30 s.
+- **No default values.** `motion_energy` was always `0.0` (MEASURED: 176 of 176 samples) because the bridge never set it. It now carries the node's `motion_band_power`, or the room value, or nothing. `fall` is driven by the rising edge of `edge_vitals.fall_detected`. Only `sensing_update` produces snapshots, which removes the phantom aggregate device that `edge_vitals` frames created. `present_still` now maps to 0 % motion instead of 100 %.
+- **Rates (§3.7).** Binary states publish on change, plus a 60 s retained heartbeat, as §3.5 already specified. Sensors keep their configured rates.
+- **Stable device identity (§3.8).** The default client id is now `wifi-densepose-<8 hex>`, persisted in `<data-dir>/mqtt_client_id`. §3.8 specified `wifi-densepose-<hostname>`; a persisted random id avoids a hostname dependency and survives hostname changes. `--mqtt-client-id` still overrides it.
+
+### 11.2 Evidence
+
+Unit tests (CODE-DERIVED, run with `cargo test -p wifi-densepose-sensing-server --features mqtt --lib -- mqtt:: semantic::`): `mqtt::planner::tests` covers the entity → state mapping, unavailable-without-source, warmup, on-change with heartbeat at a 73 frame/s input, sensor rates, reset and privacy mode. `mqtt::bridge::tests` covers message-type filtering, fall edges and motion energy. `mqtt::config::tests` covers client-id persistence across two "restarts" in a temp dir, override and malformed-file recovery.
+
+Live measurement (MEASURED, 2026-10-02): one ESP32 node streaming CSI and `edge_vitals` over UDP to a macOS host; `sensing-server --source esp32 --mqtt` against `eclipse-mosquitto:2` in Docker on a non-default port; every topic captured with a `paho-mqtt` subscriber on `#`. "Before" is `03a89793` (main), "after" is this change, built `--release --features mqtt`, same command and window.
+
+```bash
+# Broker: mosquitto.conf = "listener 1883 0.0.0.0 / allow_anonymous true / persistence false"
+docker run -d --rm -p 127.0.0.1:18830:1883 \

+# A paho-mqtt subscriber on '#' starts 2 s before each run.

+  --no-mdns --data-dir <dir> --mqtt --mqtt-host 127.0.0.1 --mqtt-port 18830
+```
+
+| Measure (180 s window unless noted) | Before (`03a89793`) | After |
+|---|---|---|
+| HA devices announced in run A | 2 (one phantom aggregate + `-node1`) | 1 (`-node1`) |
+| Entities announced per device | 20 | 15 |
+| Entities that received state (node device) | 6 | 10 |
+| Announced entities without state that still reported `online` | 14 | 1 (`fall`: an event, and no fall occurred) |
+| `presence/state` messages (node device) | 6,814 (37.9 / s) | 4 (one per change, plus 60 s heartbeat) |
+| `motion_energy` values | `0.0` in 176 of 176 | node band power, 177 samples |
+| Device id, run A → run B (restart, same `--data-dir`) | `wifi-densepose-<pid A>` → `<pid B>` (4 devices on the broker after B) | same persisted id in both runs (1 device) |
+| `offline` published on SIGTERM | no | no (unchanged; see 11.3) |
+| Same, plus `--privacy-mode` (75 s, fresh `--data-dir`) | — | 13 entities announced; no `heart_rate`, `breathing_rate` or `pose` topic for that device |
+
+After the change, five announced entities had no state: `heart_rate` and `breathing_rate`, because no calibration had been run; `someone_sleeping` and `possible_distress`, which depend on them; and `fall`, which is an event and no fall occurred. The first four were `offline`. `fall` was `online`, because the node sent `edge_vitals`. Before the change all 14 entities without state still reported `online`. Only one node was streaming during this measurement. #2085 used five nodes and measured about 73 `presence` messages per second per node.
+
+### 11.3 Not done
+
+- Semantic precision/recall on real captures. The figures in `semantic-primitives-metrics.md` have no reproducer in the repository and stay CLAIMED.
+- Zone and threshold files, `--semantic*` / `--no-semantic` flags on `sensing-server`, the `reason` attribute (§3.12.4), and `semantic_events.jsonl`.
+- MQTT last-will and offline-on-shutdown (§3.6). The server registers no LWT and SIGTERM does not publish `offline`, so availability stays as last published after the server stops.
+- Matter consumption of the semantic states.

+## Amendment 1 — vendor CSI on MT7981, still unvalidated
+
+- **Date**: 2026-09-19, recorded here 2026-10-01
+- **Status**: proposed. One board model (two units). The hardware gates below are still open.
+
+The 2026-07-18 decision said the public `mt76` tree has no supported CSI export,
+and that a firmware change might be required before physical CSI exists. Both
+statements need a narrower reading.
+
+Mainline `openwrt/mt76` still has no CSI export. MediaTek's public OpenWrt feed
+does: vendor id `0x0ce7`, MCU event `0xc2`, patch
+`1001-wifi-mt76-mt7915-csi-implement-csi-support`. On a Wavlink WL-WN586X3
+Rev A (MT7981BA + MT7976CN + MT7531AE) that patch, rebased onto the `mt76`
+revision pinned by OpenWrt 24.10.8, produced complex samples without a firmware
+blob swap. The `0xc2` hook is already in the MT7981 firmware that the OpenWrt
+24.10.8 image carries. The
+rebased patch and the two userspace fixes are in `firmware/openwrt-wn586x3/`.
+
+What the first capture was: one record, 2.4 GHz, 20 MHz, legacy OFDM, 64
+subcarriers, a single chain. CSI arrived only while a client sent frames.
+The rate is client traffic, not a sensor sample clock. The capture is not in
+this repository.
+
+What it was not:
+
+- Not a calibration, a sequence check, a timestamp check, or a repeatability run.
+  The label on the wire is `mediatek:physical-unvalidated`. Plain `mediatek` stays
+  reserved for a frame that has passed those gates.
+- Not a 4x4 array. Each radio is two chains. The four antennas are a 2.4 GHz pair
+  and a 5 GHz pair. Two routers are two receivers. Cross-box phase is not a
+  shared local oscillator, so it is not a beam.
+- Not the OpenWrt One or the BPI-R3. Those remain the upstream-friendly targets
+  in the original decision. The WN586X3 is the board this path was actually run on.
+
+`wifi-densepose-mtk-bridge` translates `mt76-vendor` JSON, or an MtkCSIdump
+datagram, into ADR-267 MTC1 and sends it to the sensing server. The server keeps
+one snapshot and a bounded ring of per-subcarrier amplitude and phase per
+`device_id`. It runs `mediatek-amplitude-heuristic-v0` on mean and peak amplitude,
+and `activity-index-v0` on per-subcarrier fluctuation. Both are `CLAIMED`. Neither
+is the ESP32 vital-sign path.
+
+One measured property supports further work, and nothing more. Offline, on six
+local dump captures from two units (2.4 GHz, HT20, chains rx0 and rx1 of transmit
+stream 0), the cross-chain phase `arg(H0·conj(H1))`, summed over subcarriers,
+moved 0.014-0.039 rad (p50) between adjacent frames for well-sampled
+transmitters. Raw per-chain phase moved about 1.56 rad (p50), which is what
+uniformly random phase gives (MEASURED; reproducer
+`scripts/mediatek-csi-phase-stability.py`). That shows a stable observable inside
+one radio. It does not show that the observable tracks people.
+
+The operator guide is [`docs/mediatek-router-csi.md`](../mediatek-router-csi.md).

+## Amendment 1 — PPDU types `Legacy` and `Unknown`
+
+- **Date**: 2026-09-19
+- **Status**: proposed. Demonstrated on one WL-WN586X3 capture. Not a maintainer acceptance.
+- **Scope**: `PpduType` discriminants only. The 72-byte header layout, CRC,
+  payload ordering, flags, and caps are unchanged.
+
+### What changed
+
+`PpduType` gains two variants:
+
+| Value | Name | Meaning |
+|---|---|---|
+| 6 | `Legacy` | Pre-HT: 802.11b CCK or 802.11a/g OFDM |
+| 7 | `Unknown` | A PPDU format the producer could not classify |
+
+Values 1-5 (`Ht`, `Vht`, `HeSu`, `HeMu`, `Eht`) are untouched.
+
+### Why
+
+The original set assumed every CSI report would be HT or later. The first real
+MT7981 capture disproved that. A Wavlink WL-WN586X3 (MT7981B + MT7976C) running
+an OpenWrt 24.10.8 image built with the patches in `firmware/openwrt-wn586x3/`
+reported `rx_mode = 1` (`MT_PHY_TYPE_OFDM`) for a client associated on 2.4 GHz
+channel 6 at 20 MHz. The bridge had no way to express it and dropped the frame.
+
+That was a real data loss, not a corner case. MediaTek's CSI driver treats legacy
+OFDM as a first-class mode: `mt7915_vendor_csi_tone_mask` skips only
+`MT_PHY_TYPE_CCK`, and its `mode_map` is keyed by `MT_PHY_TYPE_OFDM`, `_HT`,
+`_VHT` and `_HE_SU`, giving OFDM its own tone-mask group
+(`1001-wifi-mt76-mt7915-csi-implement-csi-support.patch:1070-1088`). Association
+and management exchanges are legacy-rate by design, so a sensing deployment will
+see these continuously.
+
+`Unknown` exists so the enum's gaps (5-7 and 12 in `mt76_phy_type`) and future
+modes are carried explicitly rather than guessed at or dropped. It also covers
+transports that omit the field: the MtkCSIdump UDP datagram carries no `rx_mode`,
+and reporting `Unknown` there is honest where defaulting to a concrete format was
+not.
+
+### Compatibility
+
+- **Forward, not backward.** A decoder built before this amendment rejects
+  discriminants 6 and 7 with `UnknownPpduType`, because the original parser
+  rejects unknown types by design. `TryFrom<u8>` returns `Err` rather than
+  panicking, so an old decoder fails safely — it just drops legacy frames, and
+  does so silently. **Rebuild MTC1 consumers after this codec change.**
+- **Scope is narrower than "the workspace".** `wifi-densepose-hardware` defines
+  three independent `PpduType` enums — `csi_frame.rs` (ESP32),
+  `qualcomm_csi.rs`, and `mediatek_csi.rs` — and this amendment touches only the
+  MediaTek one. Neither of the others changes, so no other vendor bridge is
+  affected. The complete set of `mediatek_csi::PpduType` consumers is:
+  `wifi-densepose-hardware`'s own `mediatek-csi-sim` binary,
+  `wifi-densepose-mtk-bridge`, and `wifi-densepose-sensing-server`, which renders the
+  value with `{:?}` and so needed no code change. In particular the
+  `ppdu_type > 3` bound in `bootstrap_baseline.rs` is fed from the **ESP32**
+  enum via `CsiGridKey::from_frame(&Esp32Frame)`, not from MediaTek frames, so
+  `Legacy` and `Unknown` cannot reach it.
+- Because the variants were added rather than renumbered, and Rust requires
+  exhaustive matches, the compiler locates any consumer that must be updated.
+  Nothing outside the files above needed one.
+- Producers must emit 6 only for frames that genuinely are pre-HT, and 7 only
+  where the format is truly unclassified. Neither is a dumping ground for a
+  mapping the producer has not done.
+- The mapping from `rx_mode` to `PpduType` is now infallible, so no MTC1 producer
+  may drop a frame on PPDU grounds.
+- Unchanged: synthetic provenance still cannot be cleared by downstream code.
+
+### Observed dimensions
+
+The same capture assembled to 1x1x64. That is the client's behaviour, not a
+protocol limit: the handset sent single-stream frames to a 2.4 GHz 20 MHz AP.
+Expect 1x2 or 2x2 on 5 GHz, and size consumers for the chipset profile's
+`max_chains` rather than for what one capture happened to show.

+# ADR-379: An OTA'd image confirms itself with a bounded health check, or rolls back
+
+**Status:** Proposed. Hardware-verified on 2026-09-29 on an ESP32-S3 (node 4) and an ESP32-C6 (node 5).
+**Date:** 2026-09-29
+**Numbering:** On 2026-10-02 `main` had up to ADR-378 and open PRs claimed
+nothing higher. If another branch also takes 379, renumber whichever merges
+second.
+
+## Context
+
+Every 16 MB node was flashed with `CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE=y`
+(`sdkconfig.defaults.16mb`). With that option the bootloader starts a freshly
+OTA'd image in `ESP_OTA_IMG_PENDING_VERIFY`. The app must then call
+`esp_ota_mark_app_valid_cancel_rollback()`. If it doesn't, the bootloader marks
+the image `ABORTED` at the next reset and boots the previous slot.
+
+Nothing in `firmware/esp32-csi-node/main` made that call, and `nm` on the ELF
+confirmed the symbol was not linked. RUNBOOK.md said an
+`ota_rollback_boot_check()` "sits in the app", but no such function existed
+anywhere in the tree. The consequences:
+
+- An image delivered by `POST /ota` ran until the next reset, then reverted
+  silently. OTA updates were not durable.
+- While the image was pending, `esp_ota_begin()` refused a second OTA with
+  `ESP_ERR_OTA_ROLLBACK_INVALID_STATE`.
+- Nothing checked health, so a bad image was never rolled back on purpose. It
+  only reverted if it happened to crash or be power-cycled.
+
+A second defect meant none of this was ever reached: **OTA never succeeded
+on this firmware before this change.** MEASURED on 2026-09-29, on node 4 (an
+ESP32-S3 running the v0.8.12 16 MB build, with the OTA key provisioned):
+
+- A `POST /ota` of a valid 1,228,672 B image logged `OTA update started`, then
+  `stack overflow in task httpd`, then `rst:0xc RTC_SW_CPU_RST`. The node came
+  back on its old slot. Both attempts failed the same way.
+- The cause: the server used `HTTPD_DEFAULT_CONFIG()`, which gives a 4096 B
+  task stack. The handler held a 1 KB receive buffer on that stack, while
+  calling `esp_ota_*` and formatting a float progress log.
+
+## Decision
+
+At boot, `ota_health_start()` (in `main/ota_health.c`, called early in
+`app_main`) reads the running partition's state:
+
+| state | meaning here | action |
+|---|---|---|
+| `PENDING_VERIFY` | just OTA'd, rollback armed | run the health check |
+| `VALID` | USB-flashed with `ota_data_initial.bin` (the bootloader writes VALID), or already confirmed | nothing |
+| `UNDEFINED` | selected by a build without rollback; boots unconditionally | nothing |
+| `NEW` | bootloader lacks rollback, so it never promoted the image | nothing |
+| error (`NOT_FOUND`/`NOT_SUPPORTED`) | no otadata entry, or factory partition | nothing |
+
+For this table I read the ESP-IDF v5.5 source: `bootloader_utility.c`
+(`set_actual_ota_seq`, the NEW to PENDING_VERIFY to ABORTED transitions) and
+`esp_ota_ops.c`.
+
+**The health check.** A low-priority task polls once a second and feeds
+`ota_health_step()`, which is a pure function in `ota_health.h`:
+
+- **Signals, both latched:** the STA got an IP (`IP_EVENT_STA_GOT_IP`, via
+  `ota_health_note_got_ip()` in `main.c`'s handler), and the stream sender
+  accepted at least one CSI frame (`csi_collector_get_send_ok_count() > 0`).
+  The second signal covers driver callback, serialization and `sendto()`
+  together.
+- **Minimum uptime** `CONFIG_OTA_HEALTH_MIN_UPTIME_S` (default 30 s): the image
+  is not confirmed before this point even with both signals present. An image
+  that crashes soon after starting its pipelines still reverts, because a crash
+  while pending is a rollback.
+- **Deadline** `CONFIG_OTA_HEALTH_TIMEOUT_S` (default 120 s, measured from
+  boot). Both signals are required by then. The minimum uptime is clamped to
+  the deadline.
+- **Pass:** `esp_ota_mark_app_valid_cancel_rollback()`, which logs
+  `marked valid after <reason> in <ms> ms`.
+- **Fail:** logs `health check failed: <reason>, rolling back`, then calls
+  `esp_ota_mark_app_invalid_rollback_and_reboot()`. If no other bootable slot
+  exists, that call returns an error. The node then logs and stays up rather
+  than reboot-looping.
+- **Terminal verdict:** once the check has confirmed or rolled back, it never
+  changes.
+
+**Negative-test hook.** `CONFIG_OTA_HEALTH_FORCE_FAIL` (default n, test only)
+makes the check roll back at the point where it would have confirmed. Use it to
+prove rollback end to end.
+
+**Remote visibility.** `GET /ota/status` now includes `ota_state` (`valid`,
+`pending_verify`, `new`, `undefined`, `other`, or `none`). An operator can
+confirm durability without a serial console.
+
+**The httpd stack.** The OTA/WASM HTTP server now sets `config.stack_size =
+CONFIG_OTA_HTTPD_STACK_SIZE`, which defaults to 8192. Three smaller changes go
+with it:
+
+- The OTA receive buffer is static rather than on the stack. Handlers run one
+  at a time on the single httpd task, so one buffer is enough.
+- The progress log prints an integer percent instead of a float.
+- `GET /wasm/list` keeps its 2 KB JSON buffer on the heap, not the stack.
+
+`recv_wait_timeout` stays at 30 s. Each `POST /ota` and `POST /wasm/upload` now
+logs `httpd stack after <handler>: N of M bytes never used`, so the size can
+be re-tuned from device measurements.
+
+Sizing: this is an estimate from static data, not a device measurement. It
+comes from a `-fstack-usage` build of the S3 16 MB configuration with IDF v5.5.
+
+- **Frame sizes along the OTA path** (bytes):
+
+  | function | bytes |
+  |---|---|
+  | `httpd_thread` | 144 |
+  | `httpd_sess_process` | 32 |
+  | `httpd_req_new` | 176 |
+  | `httpd_uri` | 64 |
+  | `ota_upload_handler` | 192 (1,216 with the old 1 KB buffer) |
+  | `esp_ota_end` | 48 |
+  | `image_validate` | 304 |
+  | `esp_image_verify` | 32 |
+  | `image_load` | 80 |
+  | `process_segments` | 112 |
+  | SHA-256 | about 110 |
+  | mmap/flash read | about 190 |
+
+- That chain comes to about 1.5 KB now, and about 2.5 KB with the old buffer.
+- Two things are not in the static data:
+  - libc's `vfprintf` behind every `ESP_LOG`. This build uses full newlib,
+    not nano, and the old progress line formatted a float.
+  - The flash-chip driver, which is reached through function pointers.
+
+  Together they plausibly add 1 to 1.5 KB. That explains an overflow at 4096
+  with the old handler.
+- The WASM upload path adds `wasm_upload_process` (336) and
+  `rvf_verify_signature` (352), plus a wasm3 module load that wasn't measured.
+- 8192 leaves roughly 4 to 5 KB above the estimated worst case, and costs
+  4 KB of internal RAM. The high-water-mark log is the check on that estimate.
+
+When the build has no `CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE` (the 8 MB S3 and
+4 MB C6 CI lanes), both entry points compile to no-ops.
+
+## Consequences
+
+- OTA updates become durable on rollback-enabled nodes once the image passes
+  the check. A second OTA is accepted after confirmation, which can come as
+  early as `MIN_UPTIME_S`.
+- A bad image now reverts instead of limping, but "bad" only means it failed
+  to reach the network or deliver CSI. An image that passes and then
+  misbehaves later is not caught.
+- If the AP is down when a node boots an OTA'd image, a good image rolls back.
+  That is the safe direction: push it again later.
+- Mock/QEMU builds that skip Wi-Fi can never pass. They must not enable
+  bootloader rollback, and none do today.
+- Bootloader capability is still invisible remotely (RUNBOOK §2). A node
+  whose bootloader lacks rollback reports `ota_state: "new"` after an OTA. That
+  is the first remote hint of which bootloader a board has.
+
+## Evidence
+
+- Host test `firmware/esp32-csi-node/test/test_ota_health.c` runs in
+  `make host_tests`, which CI runs. It covers pass, each timeout reason, the
+  terminal verdict, force-fail, the clamp, and zero soak. SYNTHETIC: it

+# ADR 380: Loopback UDP tee for second consumers of the CSI stream
+
+## Status
+
+Proposed. Unit tested, and smoke tested on loopback: a datagram sent to the
+server arrived byte for byte at the tee target. Not yet exercised against a
+live multi node fleet.
+
+Date: 2026-09-28
+
+Numbering: On 2026-10-02 `main` had up to ADR 378 and open PRs claimed nothing
+higher; ADR 379 is the OTA first-boot health check. If another branch also
+takes 380, renumber whichever merges second.
+
+## Context
+
+A five node deployment (four ESP32 S3, one ESP32 C6) streams ADR 018 frames to
+one sensing server. A second consumer cannot see the raw stream.
+
+Each node sends to a single `target_ip` (`firmware/esp32-csi-node/main/stream_sender.c`).
+The server's WebSocket and REST outputs carry per node amplitude only: no
+phase, no I/Q, no sequence number, and no `0xC511A110` sync packets. A fusion
+host that aligns CSI with camera, radar, or lidar needs all of those. Binding a
+second listener to the CSI port is not an option, and an external relay in
+front of the port would make every source loopback, which the ADR 296
+allowlist always admits.
+
+## Decision
+
+`--udp-tee` (env `RUVIEW_UDP_TEE`) copies every datagram the source allowlist
+admits, byte for byte, to up to four `ip:port` targets.
+
+- Targets must be loopback, so raw CSI never leaves the host through the tee.
+- A target may not use port 0 or the listener's own port, which would loop.
+- Sends are non blocking. A copy that cannot be queued is dropped and counted,
+  so a slow consumer never stalls the receive loop.
+- The copy happens after the ADR 296 allowlist check and before any parsing,
+  so consumers see exactly what the server admitted, in every wire format.
+- The tee is off unless configured.
+
+## Consequences
+
+A fusion host or Cognitum cog can subscribe to the full data plane by reading
+a loopback port. A consumer that today binds the CSI port itself can keep its
+code and move to the tee port instead.
+
+The tee is byte transparent, so it needs no change when the ADR 018 header or
+a later wire version changes.
+
+Each target costs one `send_to` per admitted datagram. Four targets is the
+limit.

+# ADR-381: Node self-survey from pairwise ranging (check mode first)
+
+- **Status**: Proposed
+- **Date**: 2026-10-04
+- **Deciders**: RuView maintainers; acceptance pending
+- **Tags**: node-positions, ranging, ftm, uwb, multistatic, least-authority
+- **Related**: ADR-018 (ESP32 wire format), ADR-110 (ESP-NOW time sync),
+  ADR-141 (privacy control plane), ADR-144 (UWB range-constraint fusion),
+  ADR-281 (BLE Channel Sounding ranging evidence), ADR-308 (placement
+  optimizer), rufield ADR-261 (BLE evidence and Channel Sounding adapter
+  boundary, `vendor/rufield/docs/ADR-261-ble-evidence-and-channel-sounding.md`)
+- **Issues and PRs**: #1804, #1866, #2109 (show which nodes use the default
+  position), #2133 (give the governed fuser the configured node positions)
+
+## Context
+
+Node positions reach the sensing server only through `--node-positions`. The
+operator types it by hand, keyed by node id (`id:x,y,z;...`) or by list index
+when the prefix is omitted. Three kinds of mistake pass silently today:
+
+- **Wrong ids.** A config keyed by ids that do not match the live nodes looks
+  applied and does nothing (#1804, #1866). #2109 makes the fallback to the
+  default position visible, and #2133 makes sure both fusers receive the
+  map. Neither can tell whether a correctly-keyed position is *right*.
+- **Wrong units.** Positions measured in feet and typed as metres are 3.28×
+  too large. Nothing checks the scale.
+- **Stale positions.** A node moved after setup keeps its old coordinates.
+
+Each one degrades multistatic fusion without an error. The repository has no
+node-to-node ranging and no anchor-free solver. ADR-144 models
+anchor-to-*tag* UWB ranges for people tracking
+(`wifi-densepose-mat/src/localization/range_constraint.rs`), not ranges
+between the fixed nodes themselves. ADR-281 computes BLE Channel Sounding
+ranging evidence, but there is no CS-capable radio in the fleet: rufield
+ADR-261 notes that the ESP32-S3 does not implement CS.
+
+The ESP32-S3 and C6 nodes do support Wi-Fi Fine Timing Measurement (802.11mc
+RTT, station initiator ↔ SoftAP responder) in mainline ESP-IDF. So a ranging
+source exists on hardware we already have. The question is how good it is.
+
+### What FTM measured
+
+Bench, 2026-10-04 (UTC): two ESP32-S3 boards (rev v0.2), ESP-IDF v5.5
+`examples/wifi/ftm`, SoftAP responder on channel 1 at 20 MHz, 32 FTM frames
+per session, line of sight, tape ground truth. All rows MEASURED; the
+reproducer is in Appendix A.
+
+| Tape (m) | Result |
+|---|---|
+| 0.00 | median 0.00 m |
+| 0.76 | median 0.00 m. Readings clamp to 0 below about 0.8 m. The first three sessions after a responder start read 1.8 to 3.0 m |
+| 1.14 | five responder starts: medians 0.60, 1.50, 2.25 and 3.08 m, plus a 7.7 m run at −68 dBm with a 1.92 m session spread (placement outlier) |
+| 3.71 | median 7.80 m (one start) |
+
+- **Precision within one responder start:** ±0.2 to 0.4 m (standard
+  deviation 0.19 to 0.31 m). A 40-session run over about two minutes showed
+  no drift beyond that.
+- **Bias between responder starts:** −0.5 to +1.9 m at 1.14 m, with the
+  boards untouched. A plain-versus-auto-start responder A/B test showed the
+  responder build is not the cause.
+- **Quantisation:** every distance is a multiple of 0.15 m (1 ns of RTT).
+- **Not tested:** 40 MHz, other channels, `ftm -R -o` offset calibration, a
+  second pair, non-line-of-sight, CSI coexistence, raw t1..t4 timestamps.
+
+FTM is precise inside one start and inaccurate across starts. It can catch
+mistakes worth metres. It cannot place a node to decimetres. UWB (Qorvo
+DW3000 family) is the expected accuracy path: about 0.1 m line of sight is
+CLAIMED by the vendor, and we have no measurement of our own yet.
+
+## Decision
+
+### 1. A source-agnostic `RangeObservation` record
+
+```text
+RangeObservation {
+    initiator: u8,             // node_id, as in --node-positions
+    responder: u8,
+    range_m: f64,              // session median
+    sigma_m: f64,              // session spread, 0 if unknown
+    method: Ftm | Uwb | BleCs | Manual,
+    samples: u16,              // valid frames / exchanges
+    rssi_dbm: Option<i16>,
+    bandwidth_mhz: Option<u16>,
+    at_us: u64,                // host receive time
+    responder_boot: Option<u32>,  // boot counter or nonce of the responder
+    calibrated: bool,          // set only by the host calibration step
+}
+```
+
+`responder_boot` is required for calibration. The FTM bias moved with every
+responder start, so an offset is only valid within the boot it was measured
+in.
+
+On the wire, nodes report ranges either in a new ADR-018-style packet with
+its own magic, or as an extension of the existing sync packet. This ADR does
+not choose between them. The host-side record and solver come first. The
+wire format follows the first firmware that emits ranges.
+
+### 2. Host-side check mode (warn-only)
+
+Given the configured positions and a batch of observations, check mode
+reports:
+
+- **Per-link residuals.** `measured − ‖p_a − p_b‖`, with a tolerance of
+  `floor + k·σ`. σ is the larger of the median session sigma and the spread
+  across sessions. Each link is `ok`, `outlier`, `too_short` (configured
+  length below the source's minimum), `weak` (every session below the RSSI
+  gate), or `noisy` (σ above the source's maximum).
+- **Unit mismatch.** A least-squares scale `s` in `measured ≈ s·expected`.
+  If `s` sits within a band of 0.3048 (feet), 0.0254 (inches), 0.01 (cm) or
+  0.001 (mm), and rescaling removes outliers, the check reports the unit.
+- **Id swap.** For up to 8 ranged nodes, it scores every assignment of the
+  configured positions to ids. The cost is a truncated quadratic in residual
+  over tolerance, so one bad link cannot dominate. If another assignment
+  cuts the cost to at most half and the configured cost is material, the
+  check suggests that assignment, reported as `(node, position_of)` pairs.
+- **Moved node.** If most of a node's links are outliers (at least 2, and a
+  strict majority), the node was probably moved. Outlier links left over are
+  reported one at a time as possible bias, a body or wall in the path, or a
+  bad session, and not as a configuration error.
+- **Unknown and unranged nodes.** Observations naming unconfigured ids, and
+  configured nodes that no scored link reaches.
+
+Distances do not change under rotation, reflection or translation, so check
+mode compares distances and never coordinates. Where the layout is
+symmetric, it says so instead of guessing:
+
+- A relabelling that is a symmetry of the layout is **invisible**. For
+  example, ids rotated 180° in a rectangle of corner nodes. Check mode
+  reports such a layout as consistent.
+- When several assignments fit equally well, check mode prefers the one that
+  changes the fewest ids, since a typo moves few. It reports how many
+  assignments tied. If the fewest-changes assignments are themselves tied,
+  as with a swap along one wall of a rectangle (its mirror image is the
+  opposite wall's swap), it reports `id_swap_ambiguous` and names nothing.
+
+Corner-mounted nodes in a rectangular room are the common case and are
+nearly symmetric. Operators should expect ambiguity reports there, and a
+fifth node off the axes removes most of them.
+
+**Authority.** Check mode never writes positions, never edits config, and
+never changes fusion. Its output is a report for the startup log and a
+read-only status field. The report shape is JSON-serialisable; the field
+name follows #2109's `node_positions` block once that lands.
+
+**Tolerances come from measured data:**
+
+| Source | `floor_m` | `calibrated_floor_m` | `max_sigma_m` | `min_expected_m` | Basis |
+|---|---|---|---|---|---|
+| FTM, ESP32-S3, 20 MHz | 2.0 | 0.6 | 1.0 | 1.0 | MEASURED, bench above: bias −0.5 to +1.9 m between starts; spread ≤ 0.31 m within a start (the 1.92 m outlier excepted); clamp below about 0.8 m |
+| UWB | 0.3 | 0.3 | 0.3 | 0.0 | ESTIMATE until our own UWB bench. Vendor accuracy is CLAIMED |
+
+With `floor_m = 2.0`, the one 3.71 m start (+4.1 m) would be flagged as a
+single-link outlier. That is uncalibrated FTM as it stands. Single-link
+outliers stay low-severity on purpose, and the strong findings (unit, swap,
+moved node) need several links to agree.
+
+### 3. Per-boot calibration
+
+An offset is recorded per `(initiator, responder, responder_boot)` from
+sessions at a known reference distance of at least 1.0 m:
+`offset = median(range) − reference`. It applies only to observations with
+the same key. After a responder reboot, observations pass through
+uncalibrated and get the wider floor.
+
+Zero-separation calibration (ESP-IDF's `cm0` / `ftm -R -o`) is not used,
+because short ranges clamp to 0 on this hardware. In practice, the reference
+is one tape-measured link per responder per boot, or a UWB link once UWB
+exists. That the bias is stable over a whole boot, and not only for two
+minutes, is untested (ESTIMATE). Measuring it is the first FTM follow-up.
+
+### 4. Fill mode, gated off
+
+Fill mode (solve positions with classical-MDS initialisation, weighted
+robust SMACOF and gauge fixing, then write a file the operator passes to
+`--node-positions`) is **not implemented** and stays disabled for a source
+until all of these hold:
+
+- the source has **MEASURED** link-error evidence with a reproducer;
+- the evidence covers at least 6 ground-truth links;
+- the p90 link error is **≤ 0.3 m**.
+
+FTM's measured errors are metres, so it fails this gate. UWB is expected to
+pass it, but that is unproven. Even when the gate opens, fill mode writes a
+proposal file. The server never rewrites its own positions.
+
+### 5. Pluggable sources
+
+Every source produces `RangeObservation`, and check mode does not care which
+one did. Only the tolerance profile changes.
+
+| Source | Status | How it plugs in |
+|---|---|---|
+| **FTM** (ESP32-S3/C6) | Now, for check mode | APSTA node runs a short scheduled survey window. One node is the SoftAP responder and the others initiate a directed session. `rtt_ns`, RSSI and session spread map to `range_m`, `rssi_dbm`, `sigma_m`. Airtime cost on the CSI channel is unmeasured |
+| **UWB** (DW3000 family, e.g. DWM3001CDK over USB) | After its own bench | Two-way ranging between nodes. Shares hardware with ADR-144's anchor-tag model, but node↔node ranges feed this ADR and anchor↔tag ranges keep feeding ADR-144 |
+| **BLE CS** | When a CS-capable radio exists | Through the rufield ADR-261 adapter boundary, using ADR-281's cross-validated phase/RTT ranging. A `Divergent` anomaly drops the observation. Single-mechanism evidence gets the wider floor |
+| **Manual** | Now | A taped distance entered by the operator. Mainly useful as the per-boot calibration reference |
+
+### 6. Prototype
+
+`v2/crates/ruview-survey` implements sections 1 to 4 on the host, with no
+I/O, no clock and no randomness, and bounded inputs: 64 nodes, 10 000
+observations, 100 m range, and the swap search capped at 8 nodes.
+Integration with the sensing server is a follow-up and depends on #2109 for
+where the report surfaces. The crate's tests are SYNTHETIC: generated layouts
+with FTM-like bias and noise from the envelope above. They cover consistent
+configs, feet and centimetre mistakes, a two-id swap, a three-id rotation,
+symmetric invisibility and ambiguity, a moved node, a bench-style single-link
+outlier, a noisy link, per-boot calibration, and the fill gate.
+`examples/check_ranges.rs` runs check mode on a JSONL file.
+
+## Consequences
+
+- An operator gets a warning when ranges and `--node-positions` disagree
+  grossly, with no new authority: check mode is read-only.
+- FTM on nodes needs APSTA and a SoftAP beacon on the sensing channel. Its
+  cost to CSI yield must be measured before the firmware side ships.
+- The FTM tolerances rest on one evening with one pair. They are parameters,
+  not constants, and must be revised from more data (40 MHz, more pairs,
+  non-line-of-sight).
+- Ranges between fixed nodes are not person data. Ranges to phones or tags
+  are, and remain under ADR-141 and ADR-144.
+- A symmetric layout can hide a relabelling entirely. Check mode documents
+  this and does not claim to catch it.
+
+## Evidence rule
+
+No self-survey accuracy claim without a MEASURED reproducer: tape or laser
+ground truth, at least 4 nodes, line of sight plus at least one
+non-line-of-sight case, every number tagged. The prototype's tests are
+SYNTHETIC and show logic, not radio performance.
+
+## Alternatives considered
+
+- **Treat FTM as accurate enough to fill positions.** Rejected: the measured
+  bias between starts (−0.5 to +1.9 m at 1.14 m) and the +4.1 m at 3.71 m
+  rule it out.
+- **Drop FTM.** Rejected for now. It costs nothing on existing hardware, it
+  catches metre-scale mistakes, and it may suit coarse gating, calibrated
+  pairs within a boot, and time sync. It is parked and revisited after UWB.
+- **Zero-separation `cm0` calibration.** Rejected: readings clamp to 0 below
+  about 0.8 m.
+- **Server auto-corrects positions.** Rejected under least authority. Fill
+  mode, when enabled, writes a proposal file only.
+- **LoRa SX1280 ranging, router (MT7981) FTM, raw I/Q phase ranging,
+  CSI-amplitude ranging.** Rejected or deferred: wrong distance regime, no
+  driver support, unproven, or too inaccurate respectively.
+
+## Open questions
+
+- Does one calibration offset hold for a whole responder boot? For both
+  roles? For other initiators against the same responder?
+- Is the post-start transient (1.8 to 3.0 m in the first three sessions at
+  0.76 m) real, and how long does it last?
+- Does 40 MHz shrink the bias between starts?
+- What does an FTM survey window cost in CSI frames on the same channel?
+- Can FTM t1..t4 timestamps be tied to the CSI timestamp clock for sync?
+- The wire format: new magic, or an extension of the sync packet?

+# ADR-382: `spatial.evidence.v1` export of RF Gaussians and link observations
+
+- **Status**: proposed
+- **Date**: 2026-10-03
+- **Deciders**: RuView maintainers
+- **Tags**: rf, gaussian, spatial, evidence, wire-format, interop
+- **Related**: ADR-273 (unified RF world model), ADR-275 (RF-aware Gaussian
+  memory), ADR-142 (temporal voxel evidence). Origin of the wire format:
+  WeftOS ADR-107 §7 ("Spatial evidence engine and workspace"), amended
+  2026-10-03.
+- **Crate**: `v2/crates/ruview-spatial-evidence`
+
+Numbering: on 2026-10-03 `main` had up to ADR-378, open PRs claimed 379
+and 380, and 381 was taken by another branch.
+
+## Context
+
+`ruview-unified` keeps a map of RF Gaussians (ADR-275) and a Friis channel
+model that turns a TX/RX link into an expected amplitude. A spatial evidence
+engine fuses many sensor types (tape measurements, radar, ToF, UWB, RF) into
+an occupancy octree and promotes stable geometry (walls, furniture) into room
+models. That engine reads a versioned JSONL format, `spatial.evidence.v1`,
+specified in WeftOS ADR-107 §7.
+
+RuView should be able to feed it without depending on it, and without a
+reader of this repository having to go to another project to learn what the
+export writes. This ADR records the part of the contract RuView emits.
+
+## Decision
+
+1. A leaf crate, `ruview-spatial-evidence`, converts `ruview-unified` output
+   to `spatial.evidence.v1` lines. Its only internal dependency is
+   `ruview-unified`. The wire shapes are local serde structs; the contract is
+   the JSON, not a shared crate.
+2. It emits two record types, `rf_gaussian` and `rf_link_observation`. It
+   does not mirror the other v1 types and rejects them as unknown when
+   parsing.
+3. Every record is validated against the v1 rules below before it is
+   serialised, so a bad value fails in RuView rather than in the consumer.
+4. If WeftOS ADR-107 §7 changes the envelope or either RF body, this ADR is
+   amended in the same change that updates the crate.
+
+### Envelope (every record)
+
+| Field | Rule |
+|---|---|
+| `schema` | exactly `spatial.evidence.v1` |
+| `type` | `rf_gaussian` or `rf_link_observation` here |
+| `t_ns` | u64, ns since the Unix epoch |
+| `frame` | `room_enu` |
+| `region` | region id, e.g. `region/urth/meso/<room>` |
+| `source_id` | device or operator id, never a person |
+| `uncertainty_m` | 1σ position uncertainty, metres, in (0, 100] |
+| `provenance` | `{receipt, producer, proof}`; `proof` is `MEASURED`, `CODE` or `SYNTHETIC` |
+
+Ids (`region`, `source_id`, `receipt`, `producer`) match
+`[A-Za-z0-9._:/-@]{1,128}`. A line is at most 16 KiB.
+
+**Frame.** `room_enu` is room-local, origin at the room's SW floor corner,
+x east, y north, z up, metres. Coordinates are within ±1000 m.
+
+**Angles.** Every yaw in v1 is degrees counter-clockwise from room +x
+(east): 0 faces +x, 90 faces +y. The two RF types have no yaw field. The
+`rf_gaussian` orientation is a body-to-room quaternion, and a positive
+rotation about +z turns the Gaussian's local x axis counter-clockwise from
+east, the same sense.
+
+### `rf_gaussian`
+
+| Field | Rule |
+|---|---|
+| `position` | [x, y, z] m |
+| `scale` | per-axis σ, m, each in [1e-6, 1e4] |
+| `orientation` | quaternion `[w, x, y, z]`, finite, norm > 1e-6 |
+| `occupancy` | peak extinction, nepers/m, in [0, 1e6] |
+| `confidence` | [0, 1] |
+| `motion` | `static`, `slow` or `fast` |
+| `role`? | `absorber` or `reflector`; set only on priors sent back to RuView |
+
+The exporter maps `RfGaussian` field for field. `uncertainty_m` is the
+geometric mean of the three σ, clamped to the envelope range, because
+`RfGaussian` has no separate position covariance. The receipt is
+`gauss:<device>:<t_ns>:<index>`. A Gaussian whose provenance is `synthetic`
+is always tagged `SYNTHETIC`; a caller can lower the proof tag, never raise
+it.
+
+### `rf_link_observation`
+
+| Field | Rule |
+|---|---|
+| `tx`, `rx` | antenna positions, m |
+| `freq_hz` | [1e8, 3e11] |
+| `excess_loss_db` | `20·log10(free / measured)`, in [−60, 200]; negative is constructive multipath |
+
+The free-space reference comes from `ruview-unified`'s channel model with an
+empty map, so it is the same Friis amplitude the ADR-275 inverse update uses.
+
+### Examples
+
+These two lines are the WeftOS ADR-107 §7 examples. The crate's tests parse
+them and check that its own output has the same shape.

+
+Additive optional fields may appear inside v1 and older readers ignore them.
+New record types may also be added inside v1 (the 2026-10-03 amendment added
+`tof_depth` and `radar_range`, and an optional `sensor` block on
+`radar_track_point`); a reader that does not know a type rejects it as
+unknown rather than misreading it. Removing, renaming or changing the
+meaning of a field requires `spatial.evidence.v2`, and the parser reports a
+v2 line as a version mismatch.
+
+## Consequences
+
+- RuView output can feed a spatial evidence engine with no new runtime
+  dependency, and the contract is readable from this repository.
+- The engine can send promoted walls and objects back as `rf_gaussian`
+  priors with a `role`. That gives ADR-275's inverse update a geometric
+  starting point instead of an empty map.
+- The struct definitions are duplicated between the two projects. The
+  golden-line tests catch drift in the RF types; a change on the WeftOS side
+  still needs someone to amend this ADR and the crate.
+
+## Limitations
+
+- Nothing calls the crate yet. The sensing server does not export records,
+  and there is no adapter that turns an inbound `rf_gaussian` prior into an
+  `RfGaussian` in the live map.
+- The tests are CODE-level (deterministic conversions and validation). No
+  MEASURED claim is made about what the exported evidence does to a room
+  model.
+- `uncertainty_m` for a Gaussian is a stand-in derived from its extent.

+# ADR-383: Reject malformed HTTP request targets without stopping the transport
+
+Status: Proposed; maintainer acceptance pending
+
+## Context
+
+ADR-375 introduces the authenticated Streamable HTTP transport. Node accepts an HTTP request target that the WHATWG URL parser rejects. The current request listener lets that parser exception escape, terminating the process before route selection. A bounded loopback fixture using the public `startMcpHttp` API reproduces this with `http://[`; the original code resets the connection and exits.
+
+## Decision
+
+Catch URL construction failures at the request boundary and return HTTP 400 with the generic `invalid_request_target` error. Do not include the request target or parser exception in the response, since the target can carry a secret path. Keep route selection, token checks, origin policy, grants, protocol negotiation and JSON handling unchanged.
+
+## Alternatives
+
+Relying on Node's HTTP parser does not suffice: a syntactically accepted request target can still fail URL construction. A process-level exception handler would obscure unrelated faults and would not provide a request-specific response.
+
+## Verification
+
+MEASURED software fixture: the actual child-process HTTP transport fails the new regression on the original source (nine existing controls pass); the patched transport passes all ten focused tests. The new test also verifies subsequent health, rejected unauthenticated calls and successful authenticated initialization. Broader package checks are recorded separately against the final implementation revision. No external service, device, hardware, throughput or production deployment claim is made.

+# ADR-386: Recover CSI packet loss by missing sequence identity
+
+Status: Proposed; maintainer acceptance pending
+
+## Context
+
+The RF capture diagnostics report CSI packet loss and account for UDP reordering. The existing tracker decrements its gap count for any late sequence while gaps exist. A duplicated recovery or previously received packet therefore erases a different missing packet. For example, sequences 100, 103, 101, 101 leave 102 missing but currently report zero loss. Accurate loss diagnostics matter when distinguishing transport problems from healthy sensing input.
+
+## Decision
+
+Retain the identities of counted missing sequences within the existing 1024-sequence reorder window. Recover a gap only when deleting its identity succeeds, so a duplicate cannot recover it twice. Prune identities outside the window without erasing their historical gap counts. A confirmed counter reset clears recovery identities but preserves accumulated loss. Keep the existing frame count/rate, loss denominator, stray/reset classification and packet format unchanged.

+- Status: proposed
+- Date: 2026-10-11
+- Related: ADR-373 (bounded device readers)
+
+## Context
+
+The iPhone reader completes at its packet limit, timeout, or pre-open failure.
+After an opened WebSocket closes normally, however, it keeps the capture timer
+running despite having no remaining source of frames. A one-frame stream that
+closes immediately waits the entire requested window; an empty normal stream
+also delays its no_frames result. This wastes the user's capture time and uses
+the idle post-close interval in its reported receive rate.
+
+## Decision
+
+Finish on every close event. Retain accepted depth statistics. Preserve the
+existing relay_closed refusal for abnormal empty streams, pre-open connection
+failure, and max_frames termination. A normal empty stream still returns
+no_frames; a stream with valid depth frames remains a successful capture. The
+requested seconds field retains its existing meaning.

+## Verification
+
+An owned loopback HTTP server performs a real WebSocket upgrade and sends a
+valid one-pixel depth frame followed by a normal close handshake. The public
+reader must return promptly instead of waiting its two-second capture timeout.
+A normal empty stream and abnormal empty code1008 stream check refusal behavior;

+Small finite-state machines run inside the server, one set per node, sampled once per second ([ADR-115 §3.12](../adr/ADR-115-home-assistant-integration.md#312-semantic-automation-primitives-ha-mind), P4.5). All of them are unavailable for the first 60 s after start (warmup). After that each publishes its current state, then on every change.

+| Someone sleeping | `someone_sleeping` | `binary_sensor` | presence + motion <5% + BR ∈ [8,20] bpm for 5 min | after warmup, while breathing rate is available |
+| Possible distress | `possible_distress` | `binary_sensor` | HR ≥ 1.5× resting baseline + motion >20% + no fall, for 60 s | after warmup, while heart rate is available |
+| Fall risk elevated | `fall_risk_elevated` | `sensor` | 0–100 score: 10 per fall in 24 h + 50 × motion variance over 60 s | after warmup, while the fall detector is available |

-Heart rate, breathing rate, and pose are **biometric** entities — they are stripped from MQTT (and never published over Matter) when `--privacy-mode` is set. See [Privacy](#privacy) below.
+Per-node motion is a three-level classification, so the motion thresholds above effectively mean "moving" or "not moving". The precision and recall figures in [`semantic-primitives-metrics.md`](./semantic-primitives-metrics.md) are CLAIMED: the replay tooling they cite is not in the repository. No `reason` attribute is published yet; the explanation tags stay server-side.

-### Semantic automation primitives (10 entities)
+### Not announced

-These are the inferred high-level states that customer automations actually use. Each one is a small finite-state machine running server-side with explicit warmup, hysteresis, and refractory windows. Per-primitive precision/recall is published in [`semantic-primitives-metrics.md`](./semantic-primitives-metrics.md).
+These entities from ADR-115 §3.1 and §3.12 are not announced, because the sensing broadcast has nothing to drive them. Announcing them only produced entities stuck at "unknown" ([#2085](https://github.com/ruvnet/RuView/issues/2085)).

-| HA entity | Slug | HA component | What it fires on |
-|---|---|---|---|
-| Someone sleeping | `someone_sleeping` | `binary_sensor` | presence + motion<5% + BR ∈ [8,20] bpm sustained for 5 min |
-| Possible distress | `possible_distress` | `binary_sensor` | HR > 1.5× baseline + motion >20% + no fall, sustained 60 s |
-| Room active | `room_active` | `binary_sensor` | motion >10% in a 30-s rolling window |
-| Elderly inactivity anomaly | `elderly_inactivity_anomaly` | `binary_sensor` | idle > 2× observed-max-idle baseline |
-| Meeting in progress | `meeting_in_progress` | `binary_sensor` | ≥2 persons + low-amplitude motion for 10 min |
-| Bathroom occupied | `bathroom_occupied` | `binary_sensor` | presence + active zone tagged `bathroom` |
-| Fall risk elevated | `fall_risk_elevated` | `sensor` | 0–100 score; event fires on ≥70 crossing |
-| Bed exit (overnight) | `bed_exit` | `event` | sleeping → presence leaves bed zone between 22:00–06:00 |
-| No movement (safety) | `no_movement` | `binary_sensor` | presence + motion <1% for 30 min |
-| Multi-room transition | `multi_room_transition` | `event` | zone X exit + zone Y enter within 10 s |
+| Slug | Why not |
+|---|---|
+| `zone_occupancy`, `bathroom_occupied`, `bed_exit`, `multi_room_transition` | the broadcast carries no zones, and the server loads no zone-tag map |
+| `meeting_in_progress` | needs a 1–20 % motion level; per-node motion is three-level |
+| `pose` | `pose_keypoints` is never populated on the broadcast, and the `persons[].keypoints` skeletons are synthesized. `--mqtt-publish-pose` is accepted but logs a warning and announces nothing |

-Every state change carries a `reason` attribute (e.g. `["motion<5%", "br=12bpm", "presence=true"]`) so you can template against it in HA automations to understand why an automation triggered.
+### Publish rates and retention
+
+| Entity kind | When it publishes | QoS / retain |
+|---|---|---|
+| `presence` and semantic `binary_sensor`s | on change, plus a heartbeat every 60 s if unchanged | 1 / retained |
+| `person_count`, `motion_level`, `motion_energy`, `presence_score`, `fall_risk_elevated` | at most `--mqtt-rate-motion` / `--mqtt-rate-count` (default 1 Hz) | 0 / not retained |
+| `heart_rate`, `breathing_rate` | at most `--mqtt-rate-vitals` (default 0.2 Hz) | 0 / not retained |
+| `rssi` | at most `--mqtt-rate-rssi` (default 0.1 Hz) | 0 / not retained |
+| `fall` | once per detected fall | 1 / not retained |
+| availability | on every transition, and all topics every 30 s | 1 / retained |
+
+Before [#2093](https://github.com/ruvnet/RuView/issues/2093), `presence` was published on every CSI frame (MEASURED 37.9 msg/s with one node, 1 msg per ~45 s after the fix; see [ADR-115 §11](../adr/ADR-115-home-assistant-integration.md#11-status-note-p45-semantic-states-on-the-live-publisher-2026-10-02)).
+
+### Device identity
+
+Each node's HA device id is `wifi_densepose_<client-id>-node<N>`, where `<N>` is the node id from the CSI frames. Without `--mqtt-client-id`, the server creates `wifi-densepose-<8 hex digits>` on first start and keeps it in `<data-dir>/mqtt_client_id`, so device ids survive restarts. Keep `--data-dir` on persistent storage (a Docker volume, for example). If the file cannot be written, the server logs a warning and falls back to a per-process id for that run. `--mqtt-client-id` overrides the persisted id. Use it to pin ids across reinstalls or to run two servers against one broker.
+
+Releases before this change used `wifi-densepose-<pid>`, so every restart created a new set of devices. To remove the leftovers, publish an empty retained message to each stale `homeassistant/+/wifi_densepose_<old-id>…/+/config` topic, or delete the devices in Home Assistant.

 ### What about regulated environments?

-Run RuView with `--privacy-mode` and only the 10 inferred semantic states reach Home Assistant — heart rate, breathing rate, and pose values are stripped at the MQTT wire. Per ADR-115 §6, this passes:
+With `--privacy-mode`, heart rate and breathing rate never reach the broker; their entities are not even announced. The semantic states still reach Home Assistant, and two of them (`someone_sleeping`, `possible_distress`) are derived from those vitals inside the server, so their ON/OFF values are themselves health-related information.

- **HIPAA-style minimum-necessary** (no biometric numbers leave the device)
- **GDPR purpose-limitation** (the inferred states are the smallest dataset that supports the automation)
- **CCPA "sensitive personal information"** (no health data crosses the wire)
-
-The fall-risk-elevated / possible-distress / someone-sleeping flags still work — they're computed *inside* the sensor pipeline and only the boolean outputs are published. That's the architectural win that makes RuView deployable in care homes, hospitals, schools, and shared-housing scenarios where raw biometrics would be a non-starter.
+Privacy mode narrows what crosses the MQTT wire. It is not a compliance certification, and RuView makes no HIPAA, GDPR or CCPA compliance claim. Whether a deployment meets a regulation depends on the whole system: broker access control and TLS, Home Assistant's recorder retention, who can see the dashboards, consent, and local law. Assess that with whoever is responsible for compliance in your setting.

+
+RuView can take channel state information (CSI) from a MediaTek Filogic
+router, such as an MT7981B with an MT7976C radio running OpenWrt with
+MediaTek's vendor CSI patch. The router reports CSI. A host-side bridge
+converts it to RuView's MTC1 wire format (ADR-267). The sensing server ingests
+it like any other UDP source.
+
+**Status: experimental.** This page documents a working data path, measured
+on one board model. It makes no sensing-quality claim. Frames from this path
+carry the provenance label `mediatek:physical-unvalidated`. The ADR-266
+hardware gates are still open: calibration, sequence, timestamp, and
+repeatability.
+
+Developed in whitsentry, a RuView-based project.
+
+Evidence tags used below: **MEASURED** (with a reproducer), **CODE-DERIVED**

+| Other MT7981/MT7986 boards | — | Untested. The CSI patch targets the `mt7915` driver family, so other Filogic radios may work, but nothing here shows that. |
+
+The board patch in `firmware/openwrt-wn586x3/` is specific to the WN586X3
+**Rev A**. The CSI driver patch and the two userspace fixes do not depend on
+the board.
+
+Each MT7976C radio has **two receive chains**. The WN586X3's four external
+antennas are a 2.4 GHz pair and a 5 GHz pair. It is not a 4x4 array, and two
+routers are two independent receivers, not one phased array.

+
+The route that produced the tested image (CODE-DERIVED from its build scripts)
+used the stock OpenWrt **24.10.8** `mediatek/filogic` SDK and ImageBuilder in
+an x86_64 Linux container:
+
+1. **SDK.** Unpack `openwrt-sdk-24.10.8-mediatek-filogic`, then run
+   `./scripts/feeds update -a && ./scripts/feeds install -a`.
+2. **CSI driver.** Copy the rebased `1001-...` patch into
+   `feeds/base/package/kernel/mt76/patches/`. Raise `PKG_RELEASE` in that
+   package's `Makefile` (the tested build used `99`) so the ImageBuilder
+   prefers your build over the CDN package of the same version.
+3. **mt76-vendor.** Add MediaTek's `mt76-vendor` package from
+   `mtk-openwrt-feeds` as `package/mt76-vendor`, with the bounds patch applied
+   to `src/csi.c`.
+4. **Configure and compile.** Select `CONFIG_TARGET_mediatek_filogic_DEVICE_wavlink_wl-wn586x3`,
+   `kmod-mt7915e`, `mt76-vendor`, and `libnl-tiny`. Then run
+   `make package/feeds/base/mt76/compile package/mt76-vendor/compile`.
+5. **Image.** Copy the built `.ipk` files into the ImageBuilder's `packages/`
+   and run:
+   ```bash
+   make image PROFILE=wavlink_wl-wn586x3 \
+     PACKAGES="kmod-mt7915e kmod-mt7981-firmware mt7981-wo-firmware mt76-vendor libnl-tiny"
+   ```
+6. **Check the manifest.** The image's `.manifest` must list `kmod-mt7915e`
+   at your raised release (for example `-r99`) and `mt76-vendor`. If it lists
+   the CDN release, the image has no CSI.
+
+**Rev A board patch.** An ImageBuilder cannot compile a device tree, and its
+`make image` reuses the prebuilt DTB and FIT kernel. The tested Rev A build
+compiled the patched DTB itself, rebuilt the FIT kernel around it, added the
+patched `lib/upgrade/platform.sh` as a rootfs overlay, then checked that the
+final sysupgrade image embedded that DTB. A full OpenWrt buildroot applies
+`target/` patches directly and avoids those steps. That route was not tested
+here.
+
+Flash only a Rev A unit, keep the stock firmware backup, and follow the
+OpenWrt wiki and forum thread for this board. Neither this guide nor the patch
+set names a LAN, an account, or a password.
+
+**Firmware blobs.** The CSI report is MCU event `0xc2`. The MT7981 firmware in
+the tested image (`kmod-mt7981-firmware`, `mt7981-wo-firmware` from OpenWrt
+24.10.8) already emits it, so no firmware blob swap was needed on the tested
+board. Other firmware versions are untested.
+
+## Arm CSI on the router
+
+CSI follows traffic from **associated clients**. With nothing associated and
+transmitting, there is no CSI. Run these on the router, as root, against the AP
+interface (`phy0-ap0` was the 2.4 GHz AP on the tested board). The sequence
+below is CODE-DERIVED from the capture scripts used on the tested board:
+
+```sh
+mt76-vendor phy0-ap0 set csi ctrl=0,0,0,0      # disarm and reset
+mt76-vendor phy0-ap0 set csi interval=1000
+mt76-vendor phy0-ap0 set csi ctrl=2,3,0,34     # frame-type filter, as used on
+mt76-vendor phy0-ap0 set csi ctrl=2,9,1,0      # the tested board (data frames)
+mt76-vendor phy0-ap0 set csi ctrl=1,0,0,0      # arm
+```
+
+Check that the driver is collecting:
+
+```sh
+cat /sys/kernel/debug/ieee80211/phy0/mt76/csi_stats   # data_cnt should climb
+iw dev phy0-ap0 station dump | grep -E "Station|signal"
+```
+
+Pull a batch:
+
+```sh
+rm -f /tmp/csi.json                         # the tool APPENDS; remove first
+mt76-vendor phy0-ap0 dump csi 64 /tmp/csi.json
+```
+
+`dump csi` needs the filename argument. Without it, the tool returns nothing.
+
+## Run the bridge
+
+```bash
+cd v2
+cargo build --release -p wifi-densepose-mtk-bridge
+B=./target/release/wifi-densepose-mtk-bridge
+```
+
+**Dump path (recommended).** Copy `/tmp/csi.json` to the host, then replay it.
+A file cannot prove it came off a radio, so `--replay` refuses to start until
+you either attest the hardware or declare the file synthetic:
+
+```bash
+$B --replay csi.json --captured-on <model>/<firmware> \
+   --node <node-name> --center-freq-khz <khz> --sink 127.0.0.1:5005
+```
+
+- `--node` is hashed into the 64-bit `device_id`. Give each router its own name.
+- `--center-freq-khz` is the AP channel's centre frequency, for example
+  `2437000` for 2.4 GHz channel 6.
+- `--captured-on` takes `<model>/<firmware>`, for example
+  `WN586X3-RevA/openwrt-24.10.8-csi`. It is logged at startup.
+
+For a continuous feed, repeat dump, copy, and replay in a loop, one loop per
+router. Keep a copy of each dump only if you need it, and never commit one
+(see below).
+
+**Streaming path (CSIdump).** Start `CSIdump phy0-ap0 <rate> 8888` on the
+router. Then, on the host:
+
+```bash
+$B --listen 0.0.0.0:8888 --csidump <router-ip>:8888 --listen-allow <router-ip> \
+   --node <node-name> --center-freq-khz <khz> --sink 127.0.0.1:5005 \
+   --record captures/<node-name>.mtkcap
+```
+
+`--listen-allow` is mandatory. Datagrams from any other source are dropped and
+counted. CSIdump disarms CSI when it receives SIGTERM. The dump path and
+CSIdump cannot share the driver's ring, so run one or the other.
+
+**No router.** The fabricated fixture exercises the whole host path. It must
+be replayed with `--synthetic`, and the server labels it `mediatek:simulated`:
+
+```bash
+$B --replay crates/wifi-densepose-mtk-bridge/fixtures/FABRICATED-mt76-vendor-dump-mt7981-bw80.synthetic.json \
+   --synthetic --node demo --sink 127.0.0.1:5005
+```
+
+The ADR-266 simulator is another synthetic source:
+
+```bash
+cargo run -p wifi-densepose-hardware --bin mediatek-csi-sim -- \
+  --profile mt7981 --udp 127.0.0.1:5005 --frames 1000 --realtime
+```
+
+Full flag reference: [`v2/crates/wifi-densepose-mtk-bridge/README.md`](../v2/crates/wifi-densepose-mtk-bridge/README.md).
+
+## Start the sensing server
+
+```bash
+cd v2
+cargo run --release -p wifi-densepose-sensing-server -- --source mediatek \
+  --activity-state <state-dir>/activity-floor.json
+```
+
+- `--source mediatek` binds the UDP receiver (loopback by default, ADR-296) and
+  does **not** start the ESP32-shaped simulator. Before this source existed,
+  `--source mediatek` bound nothing.
+- If the bridge runs on another host, bind a routable address with
+  `--udp-bind` and name the bridge host in `--udp-allow`.
+- `--activity-state` is optional. It persists each device's learned
+  quiet-room activity floor so that a restart does not relearn it.
+- `--csi-ring <n>` sets frames retained per device for inspection (default
+  256, about 0.5 MiB per 2x2 device at 64 subcarriers).
+
+Endpoints:
+
+| Route | Returns |
+|---|---|
+| `GET /api/v1/csi/mediatek/latest` | Last MTC1 snapshot, any device |
+| `GET /api/v1/csi/mediatek/devices` | One snapshot per `device_id`, with `age_ms`. Devices silent for over 30 s are omitted. |
+| `GET /api/v1/csi/mediatek/devices/:device_id/frames?n=&fields=amp,phase` | Newest `n` frames of per-chain, per-subcarrier amplitude and phase |
+| `GET /api/v1/csi/mediatek/devices/:device_id/summary` | Per-chain amplitude mean/std per subcarrier, RSSI per Rx chain, frame rate, heuristic window stats |
+| `GET /api/v1/csi/mediatek/activity?seconds=300` | About 1 Hz history of the relative activity index |
+| `GET /api/v1/sensing/latest` | Room update. On this source, `classifier` is `mediatek-amplitude-heuristic-v0`. |
+
+Check the label on every snapshot:
+
+| `source` | Meaning |
+|---|---|
+| `mediatek:simulated` | `SYNTHETIC` flag set. Nothing downstream can clear it. |
+| `mediatek:physical-unvalidated` | Real silicon, not calibrated. Everything this path produces today. |
+| `mediatek` | Real and calibrated. Reserved. Nothing emits it yet. |
+
+## What the data is, and is not
+
+**It is** complex channel estimates per receive chain from a real MT7976C
+radio, carried end to end with provenance intact.
+
+**It is not:**
+
+- **A sensor with its own clock.** The report rate is the clients' traffic
+  rate. An idle phone gives a few frames per second, and a busy one gives
+  hundreds. With no associated, transmitting client, there is no data. A
+  stationary device that keeps transmitting to the AP (an "illuminator", for
+  example an ESP32 sending a steady packet stream) gives a regular rate
+  (CLAIMED: the 09-20 and 09-24 captures below include an illuminator's
+  frames; transmitter identity was not re-checked in this analysis).
+- **Calibrated.** `scale` is 1.0 in raw firmware units. Nothing has been
+  checked against a reference. The ADR-266 gates are open.
+- **Validated for presence, motion, or vital signs.** The room output on this
+  source comes from `mediatek-amplitude-heuristic-v0` (presence and motion from
+  mean amplitude) and `activity-index-v0` (fluctuation against a learned
+  floor). Both are **CLAIMED**. Neither has been scored against labelled ground
+  truth. `activity` blocks carry `is_occupancy_estimate: false`. These outputs
+  do not feed the validated ESP32 vital-sign pipeline.
+- **Coherent across routers.** Each radio has its own oscillator. Cross-chain
+  phase is meaningful within one radio, not between two boxes.
+- **Free of personal data.** A raw dump holds client transmitter addresses
+  (MACs) and channel samples that encode movement. RuView policy (ADR-299)
+  forbids committing captures. Keep them out of the repository, and run
+  `scripts/csi-data-policy-check.sh --staged` before committing near capture
+  directories.
+
+## Evidence
+
+| Claim | Tag | Basis |
+|---|---|---|
+| A real WL-WN586X3 frame decodes and reaches the server as `mediatek:physical-unvalidated` | MEASURED (path) | First record, 2026-09-19: legacy OFDM, 20 MHz, 64 subcarriers, one chain. Its shape is pinned by `wifi-densepose-mtk-bridge/tests/hardware_capture.rs`, which uses a fabricated record. The capture itself is not in the tree. |
+| Cross-chain phase is steady frame to frame on one MT7976C radio, and raw per-chain phase is not | MEASURED (offline) | See below |
+| `mediatek-amplitude-heuristic-v0`, `activity-index-v0` | CLAIMED | No labelled evaluation |
+| ADR-266 simulator and bridge fixtures | SYNTHETIC | Labelled on the wire |
+
+**Cross-chain phase stability.** Six local dump captures from two WN586X3 units,
+2.4 GHz, 20 MHz HT frames carrying chains (tx0, rx0) and (tx0, rx1), adjacent
+frames under 100 ms apart, 56 subcarriers (DC and guard bins excluded). The
+two 2026-09-19 captures were analysed whole; the four 09-20 and 09-24 captures
+by their first 20 MB each.
+
+| Quantity, per adjacent-frame step | Well-sampled transmitters (6, at 825 to 14,104 frames each) |
+|---|---|
+| Raw per-chain phase `arg(H0[k])`, per bin, p50 | 1.557 to 1.601 rad, with 49.6 to 50.9 % of steps over π/2 |
+| Cross-chain phase `arg(H0[k]·conj(H1[k]))`, per bin, p50 | 0.023 to 0.056 rad |
+| Cross-chain phase summed coherently over bins, p50 / p90 / p99 | 0.014–0.039 / 0.205–0.358 / 0.437–0.820 rad |
+
+Uniformly random phase gives a step p50 of π/2 = 1.571 rad, and half of all
+steps exceed π/2. Raw per-chain phase is indistinguishable from that, as
+expected with per-packet CFO and phase offset. In the cross-chain term those
+offsets cancel, and the step drops to hundredths of a radian. Steps are
+wrapped, so p99 can never exceed π, and is not evidence by itself.
+
+Transmitters with few, irregular frames (229 to 595 frames) were much worse:
+coherent-sum p50 0.177 to 0.456 rad, p99 1.857 to 2.849 rad. So the result
+holds only with a steady frame rate.
+
+This shows a **stable phase observable exists** within one radio. It does
+**not** show that the observable tracks people, breathing, or anything else.
+
+Reproduce it on your own capture (one `dump csi` array per line):
+
+```bash
+python3 scripts/mediatek-csi-phase-stability.py <capture.jsonl> [max_MB]
+```
+
+The script prints transmitters as `TX-A`, `TX-B`, and so on, never addresses.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `csi_stats` `data_cnt` stays at 0 | No associated client transmitting, or CSI not armed | Associate a client and generate traffic, then re-run the arm sequence |
+| `data_cnt` stopped after a client roamed or the filter changed | Changing the CSI filter stops capture | Re-run the arm sequence ending in `ctrl=1,0,0,0`. Re-arming periodically is a reasonable guard. |
+| `mt76-vendor dump csi` prints nothing | No filename argument | Use `dump csi <n> <file>` |
+| `mt76-vendor dump csi` segfaults | Unpatched tool: the driver can return n+1 records | Rebuild with `mt76-vendor-csi-dump-bounds.patch` |
+| Bridge warns about repeated `(ta, ts, tx_idx, rx_idx)` chains | The dump file was not removed between dumps, and the tool appends | `rm -f` the file before every dump |
+| `--replay` refuses to start | Provenance not declared | Add `--captured-on <model>/<firmware>`, or `--synthetic` for fabricated input |
+| `--captured-on` is rejected | The input declares itself synthetic (sidecar, `.synthetic.` name, or capture header) | Expected. Synthetic is sticky. Use `--synthetic`. |
+| `--listen` refuses to start | No `--listen-allow` | Name the router's address or subnet |
+| `rejected_source` counts climb on `--listen` | The router's address is not in `--listen-allow` | Fix the allowlist |
+| CSIdump runs but nothing arrives | Unpatched CSIdump uses an off-by-one netlink attribute enum against this driver | Rebuild with `csidump-nl80211-attr-enum.patch` |
+| CSI stopped after CSIdump exited | CSIdump disarms CSI on SIGTERM | Re-run the arm sequence |
+| `/api/v1/csi/mediatek/devices` is empty | Server not on `--source mediatek` (or `auto` without UDP), wrong `--sink` port, or a non-loopback bridge not in `--udp-allow` | Check `--source`, port 5005, `--udp-bind`, and `--udp-allow` |
+| Two routers show as one device | Same `--node` on both bridges | Give each router its own `--node` (or `--device-id`) |
+| A frame shows `ppdu_type: legacy` | Normal. Association and management traffic is pre-HT. | None. ADR-267 Amendment 1 carries these frames rather than dropping them. |
+| Room status reads `unknown` for a device | The heuristic abstains below its confidence threshold | Expected with sparse frames. It is not an "absent" call. |
+| Room reads `absent` with `confidence: 0.0` | Every device abstained, so there is no evidence either way | Treat confidence 0 as "no information", not as an empty room |
+| Image flashes, but there is no `mt76-vendor` or CSI | The ImageBuilder used the CDN `kmod-mt7915e` | Check the manifest for your raised `PKG_RELEASE` |
