 ## [Unreleased]
 
+### Changed
+- **`@ruvnet/rvagent` startup optimization — stdio time-to-first-response ~242 ms → ~189 ms (−22%; MEASURED, median of repeated `initialize` round-trips against `dist/index.js`, this container, reproduce with a piped-stdin timer).** Two changes: (1) `./http-transport.js` is now imported **lazily** inside the `RVAGENT_HTTP_PORT` branch — it chain-loads the MCP SDK's `streamableHttp` module (~48 ms MEASURED via per-module `import()` timing), which the default stdio path never uses; (2) the advertised JSON Schemas generated from the Zod sources are memoized per tool instead of re-walking the Zod tree on every `tools/list` (matters under the session-per-server HTTP model where each session lists tools). No behavior change: 99/99 jest tests, HTTP session flow re-smoke-tested through the lazy path. The `@ruvnet/ruview` harness CLI was profiled too and left alone — 50 ms vs the ~29 ms bare `node -e ''` floor on the same box (MEASURED), i.e. already near the interpreter floor with zero dependencies.
+
 ### Fixed
+- **FastAPI health/metrics endpoints event-loop starvation.** Calling `psutil.cpu_percent(interval=1)` blocked the single-threaded async event loop for 1.0 second on every health check or metrics collection tick, stalling all incoming requests and WebSocket operations. Fixed by changing `cpu_percent` to use non-blocking `interval=None` and offloading all blocking OS metrics gathering to background thread pools via `asyncio.to_thread`. Verified event loop responsiveness via concurrency regression tests.
+- **EngineBridge now honors `WDP_GUARD_INTERVAL_US`/`WDP_SOFT_GUARD_US`/`WDP_TDM_SLOTS`+`WDP_TDM_SLOT_US`** (#1309, PR #1312, @erichkusuki). The governed trust path previously built its multistatic fuser from a hardcoded `MultistaticConfig::default()` (60 ms guard), so multi-node deployments with WiFi/ESP-NOW time sync (10–150 ms drift) failed every governed cycle regardless of configuration — while the startup log claimed the override took effect. New `StreamingEngine::set_multistatic_config()`; `EngineBridge::new()` takes an `Option<MultistaticConfig>` threaded from the same env-derived config as `AppState.multistatic_fuser`. Hardware-verified on a live 2-node ESP32-S3 setup (90 s window, 0 fusion errors; previously every cycle failed).
+- **`/api/v1/stream/pose` WebSocket reachable with `RUVIEW_API_TOKEN` set + dashboard bearer-token field** (#1310, PR #1313, @erichkusuki). Browsers cannot attach an `Authorization` header to a WS upgrade, so the Live Demo pose stream always failed when auth was on; the path is now on a narrow exact-match exemption list (mirrors `/ws/sensing`), with a regression test pinning that the exemption doesn't leak to other `/api/v1/*` paths. The QuickSettings panel gains an "API Access" field storing the bearer token in `localStorage`; the token is applied at `api.service.js` module load so the very first request carries it.
+- **Display-less DevKitC-1 boards: `sdkconfig.defaults.devkitc` build overlay** (#1308, PR #1311, @erichkusuki). The ADR-045 runtime display probe false-positives on stock ESP32-S3-DevKitC-1 (floating QSPI pins), which silently skipped the RuView#893 MGMT+DATA CSI upgrade and collapsed CSI yield to 0 pps.

CLI: bin renamed `ruview-cli` (the `ruview` bin belongs to `@ruvnet/ruview`, ADR-265 D4), version single-sourced. Distribution (ADR-265 D1–D4): new `npm-packages.yml` (3-package × Node 20/22 matrix: tests, version-literal grep gate, pack-content/size gate, tarball-install smoke test incl. the fail-closed claim-check and an ESM-import probe that would have caught the broken `require` export, README claim-check) and `ruview-npm-release.yml` (publish from CI only, `npm publish --provenance`); `ci.yml` NODE_VERSION 18→20.
+- **Empty-room field-model calibration collected nothing on real HT40 nodes — raw 128-wide frames rejected by the 56-tone model (follow-up to the deadlock fix below).** Once the status-gate deadlock was fixed, `maybe_feed_calibration` reached `feed_calibration`, but a real ESP32 HT40 node streams 128-wide amplitude vectors while the single-link `FieldModel` is the canonical 56-tone grid — so `LinkStats::update` returned `DimensionMismatch`, `feed_calibration` bubbled the error, and `maybe_feed_calibration` swallowed it at `debug` level. Net effect: `frame_count` stayed pinned at 0 on live hardware even though presence/motion/vitals (which read the global history) worked fine. Fixed by resampling each frame onto the model's canonical 56-tone grid via `HardwareNormalizer::resample_to_canonical` before feeding — the same length-only canonicalization the multistatic fusion path uses (#1170). Pinned by `field_bridge::maybe_feed_calibration_resamples_wide_frames_and_accumulates` (128-wide frame → Collecting + count 1; fails on old code). Verified live on the ESP32-S3 deployment.
+- **Empty-room field-model calibration could never start — `/api/v1/calibration/*` was a dead endpoint (frame count pinned at 0).** `POST /calibration/start` creates the `FieldModel` in `Uncalibrated`, but the per-frame server feed `field_bridge::maybe_feed_calibration` only fed observations while the model was **already** `Collecting` — and the *only* thing that sets `Collecting` is `feed_calibration` itself (on its first fed frame). The two gates deadlocked: nothing ever fed the first frame, so `calibration_frame_count` stayed 0, `status` never left `Uncalibrated`, and the SVD room eigenstructure (eigenvalue-based person counting / localization) could never calibrate — observed live as `{"status":"Uncalibrated","frame_count":0}` never advancing on a streaming ESP32 node. Fixed the guard to feed while `Uncalibrated | Collecting` so the first frame flips the model to `Collecting` and the count advances. Also made `calibration_stop` return a structured `{success:false, frame_count, frames_needed}` (with a new `FieldModel::min_calibration_frames()` accessor) instead of an opaque 500 when finalized before enough empty-room frames accumulate. Pinned by `field_bridge::maybe_feed_calibration_advances_uncalibrated_to_collecting` (asserts `Uncalibrated → Collecting` + count 0 → 1 → 2; fails on old code). Presence/motion/vitals were unaffected — they use the separate auto rolling baseline, not the field model.
 - **Multistatic fusion never ran on a mixed-mode ESP32 mesh — live bridge fed raw, un-canonicalized per-node CSI to the fuser (#1170).** `node_frame_from_state` (`multistatic_bridge.rs`) wrapped each node's **raw** amplitude vector (HT20 ≈ 64 bins, HT40 ≈ 128/192) into a struct *named* `CanonicalCsiFrame` without ever resampling, so `MultistaticFuser::fuse` tripped `DimensionMismatch` on every cycle, silently fell back to per-node sum/dedup, and spun `total_engine_errors` unbounded. Added `HardwareNormalizer::resample_to_canonical` (resample-only, **no z-score** — preserves the amplitude scale the person-score's `variance/mean²` relies on) and run every node frame through it onto the canonical 56-tone grid before fusion. Heterogeneous meshes now fuse instead of erroring. Pinned by `heterogeneous_node_counts_canonicalize_and_fuse` (mixed 64/192 → fuses), `resample_to_canonical_is_length_only_no_zscore`, and an updated `test_node_frame_conversion`; the pre-existing `engine_bridge::observe_cycle_counts_engine_errors` was retargeted to force a `TimestampMismatch` (its old 56-vs-30 setup now canonicalizes cleanly). `wifi-densepose-signal` 501 / `wifi-densepose-sensing-server` 677 tests, 0 failed.
 - **`csi_fps_ema` reported the CSI frame rate 40–840× too high under bursty UDP delivery (#1180).** `update_csi_fps_ema` only rejected deltas `≤ 0` or `≥ 1 s`, so a 36 µs intra-burst arrival delta yielded `1/dt ≈ 27 kHz` straight into the EMA — the metric measured server arrival jitter, not the node's ~40 fps production rate. Added a `MIN_PLAUSIBLE_CSI_DT_SEC = 0.005` floor (derived from the firmware's 50 fps `CSI_MIN_SEND_INTERVAL_US` ceiling, ×4 slack) and made `observe_csi_frame_arrival` keep its anchor across sub-floor bursts so the next genuine inter-frame gap measures true cadence. Pinned by `subms_burst_delta_rejected`, `burst_interleaved_with_nominal_stays_in_band`, and `observe_csi_frame_arrival_ignores_subms_bursts`.
 - **`stream_sender` ENOMEM backoff starved low-rate control packets under a weak uplink (#1183, follow-up to #1135/#1159).** The global `s_backoff_until_us` gate (triggered by the 50 Hz CSI flood at weak RSSI) also suppressed the ≤48 B, ≤1 Hz `feature_state` / mesh `HEALTH` / sync packets that contribute negligible buffer pressure, so telemetry failed essentially every cycle. Added `stream_sender_send_priority()` — bypasses the backoff gate, reports ENOMEM quietly, and never extends/resets the global streak — and routed `feature_state`, HEALTH/anomaly (`rv_mesh_send`), and sync packets through it. Also fixed the misleading `"HEALTH sent"` log that printed unconditionally even when `rv_mesh_send` returned `ESP_FAIL` (now prints `sent`/`FAILED` from the actual return). Firmware builds clean (ESP-IDF v5.4).

 - **`homecore-recorder` security review (ADR-132 surfaces) — two real bounding fixes; SQL-injection & NaN-index dimensions confirmed clean with evidence.** Beyond-SOTA review of the HA-compat state recorder (DB persistence + history + ruvector semantic search), the crux being its DB-backed SQL-injection surface. **Findings + fixes:** (1) **Memory-DoS — unbounded `get_state_history`.** The history query carried no `LIMIT`, so a wide `[since, until]` window over a high-frequency entity (a per-second sensor ≈ 86k rows/day) would load an unbounded row set into a single in-memory `Vec`. Added a hard `LIMIT MAX_HISTORY_ROWS` (1,000,000 — generous enough never to truncate a realistic history graph, bounded enough to cap the worst case); the sibling search paths were already `k`-bounded. (2) **Disk-DoS / documented-but-missing `purge`.** The README + HA-compat table advertised `Recorder::purge(older_than)` as a capability, but **no such method existed** — i.e. no retention path at all → unbounded disk growth. Implemented a **transactional** `purge` that deletes `states` + `events` strictly **older than** the cutoff (**exclusive** boundary — idempotent, no off-by-one; a row at the cutoff instant is kept) and **garbage-collects** orphaned `state_attributes` blobs (a dedup-shared blob is dropped only once its last referencing state is gone); all three deletes run in one transaction so a mid-purge failure rolls back cleanly (no states-deleted-but-events-kept corruption). **Confirmed clean with evidence:** SQL injection — **every** query in `db.rs` uses bound `?` parameters (no `format!`/string-concat of user data into SQL); the lone `format!` builds the LIKE *pattern*, which is itself bound as a parameter with `ESCAPE '\\'` and metacharacter escaping. Pinned: a state value `'; DROP TABLE states; --` is stored/queried **literally** (table survives), and a `%`/`_` in a search query matches **literally**, not as a wildcard. NaN-index poisoning (the calibration/vitals/geo class) — **structurally impossible** here: embeddings are SHA-256 → `i32` → `f32` (an `i32` cast to `f32` is always finite, never NaN/Inf), with an all-zero-digest norm guard; probed empty-index search, empty-string query, and `k=0` — all return `Ok(0)`, **no panic**. Fail-closed write path — a removal event yields `Ok(None)`, semantic-index failure is logged not propagated (best-effort, never blocks the durable SQLite write), and `EntityId` parsing failures fall back rather than panic. **6 new pinning tests** (SQL-injection literal-storage, LIKE-metacharacter literalness, history `LIMIT`, purge exclusive-boundary, purge attribute-GC-keeps-shared, purge old-events): `homecore-recorder` **19 → 25** (`--no-default-features`) / **25 → 31** (`--features ruvector`), 0 failed; the purge-boundary test is a true pin (fails deleting 2 rows under an inclusive cutoff, passes deleting 1 under the exclusive cutoff). Behaviour otherwise unchanged; Python deterministic proof unchanged (recorder is off the signal proof path).
 
 ### Added
+- **ADR-263/264/265: deep review of the RuView npm surface (`@ruvnet/ruview`, `@ruvnet/rvagent`, `@ruv/ruview-cli`) with optimization strategies recorded as ADRs.** ADR-263 reviews the published `@ruvnet/ruview@0.1.0` harness: fail-open `claim-check` on empty input (HIGH), `spawnSync` head-of-line blocking of the MCP stdio server during long `verify`/`calibrate` runs (HIGH), optionalDependencies tripling the cold `npx` install for a code path that never uses them (MEASURED, `npm i` in a clean prefix: 4 packages / 620 kB / 71 files default vs 1 package / 172 kB / 22 files with `--omit=optional`), 1 MiB `maxBuffer` truncation risk, `python -c` port-interpolation surface in `node_monitor`, hardcoded MCP server version, duplicated skill payload — optimizations O1–O8. ADR-264 reviews `@ruvnet/rvagent@0.1.0` + the private CLI **against the published registry tarball**: `exports.require` → nonexistent `dist/index.cjs` (HIGH, every CJS consumer breaks), 44 dead source-map files = 62,698 B of the 188 kB unpacked payload pointing at unshipped `../src` (MEASURED), stdio-only server described as "dual-transport" (CLAIMED capability), mixed dot/underscore tool naming, double Zod validation + hand-duplicated advertised schemas, 2-fd leak per training job, unbounded request body in the unwired HTTP scaffold, dead `detectCogBinary` candidate list, `ruview` bin-name collision — optimizations O1–O9. ADR-265 adds the cross-cutting distribution layer: an `npm-packages.yml` CI matrix (tests + pack-content/size gate + tarball-install smoke test — none of the three packages currently has any CI, and `ci.yml` pins Node 18 against `engines >= 20`), publish-from-CI-only with `npm publish --provenance`, version single-sourcing from package.json, bin/namespace ownership (the `ruview` bin belongs to `@ruvnet/ruview`), and claim-check enforcement on package READMEs/descriptions. Docs only — no runtime code changed; the findings are the work orders for the follow-up PRs.
 - **ADR-131 §11–§12: HOMECORE-UI wired to a real backend — single-origin BFF gateway + production front-end (no mock in prod).** Implements the §11 wiring decision so the dashboard stops rendering fabricated data. **Front-end (DONE + verified under Node):** `api.js` rewritten so every data accessor is async and calls the §11.2 gateway routes; the in-browser mock is demoted to a **dev-only fixture** reachable only via `?demo=1`/`HOMECORE_UI_DEMO` (§2.2); all ten panels now `await` and render a **typed empty/error state** on upstream failure (no mock fallback in production) — 3 panels converted by hand, 7 via a parallel agent swarm. **New `homecore-server` BFF gateway (`src/gateway.rs`, compile-pending — no Rust toolchain in the authoring env):** promotes `homecore-server` to the single origin (§2.1); adds `/api/homecore/*` + `/api/cal/*` merged into `build_app`, with `reqwest` + CLI/env flags (`--calibration-url`/`--calibration-token`/`--apps-dir`/`--gateway-timeout-ms`). Real handlers: calibration **reverse-proxy** (W2), `GET /api/homecore/rooms` with the §11.3 **RoomState adapter** (`breathing`→`breathing_bpm`, `heartbeat`→`heart_bpm`, `None`→`null` preserving not-trained-vs-withheld, injected `anomaly.threshold`/`room_id`), **COG supervisor** over `/var/lib/cognitum/apps/` (W4), and **appliance metrics** from `/proc` + TCP service probes (W6); SEED-device/appliance routes (seeds/federation/witness/privacy/settings/automations/events-history/hailo/tokens — W3/W5) return a typed `503 upstream_unavailable` and the UI shows error states. **Tests:** front-end **5 files green** — import-graph, boot, render-smoke (22), interaction (3), and a **new prod-errors suite (13)** that runs with demo OFF + gateway unreachable and proves every panel renders an error state, never mock, never throws (it caught + fixed a real unhandled-rejection in the events automation builder). **Gateway compiled, tested, and run on Rust 1.89:** `cargo test -p homecore-server --no-default-features` = **12/12 pass** (6 gateway + 6 UI mount); the binary was **run live** — `GET /api/homecore/appliance` returns real `/proc` metrics + TCP service probes, unauth → `401`, `cogs` → `[]` (no apps dir), SEED-tier → typed `503`, and against a mock calibration upstream the `/api/cal/*` proxy passes through (`200`) and `GET /api/homecore/rooms` adapts `RoomState` to the UI shape (`breathing`→`breathing_bpm`, `heartbeat:null`→`heart_bpm:null`, injected `anomaly.threshold`/`room_id`). **Live testing caught + fixed a real bug** — a double-`v1` segment in the `/api/cal/*` proxy URL. **Remaining (intrinsic, not an env limit):** W3/W5/W6-Hailo/federation depend on services/hardware **not in this repo** (recorder/automation HTTP wrappers, real SEED nodes, Hailo stat source), so they return honest `503`s rather than fabricate data; W1/W2/W4/W6-appliance are functional now. ADR-131 §10/§12.1 updated with per-wave status.
 - **ADR-131: HOMECORE-UI — the complete operational dashboard for the two-tier Cognitum stack, served by `homecore-server` at `/homecore`.** A zero-dependency, no-build-step vanilla TS/JS + CSS frontend (the `rufield-viewer` "Axum + vanilla-JS" pattern) that extends the Cognitum Appliance shell as a first-class nav section (Framework | Guide | Cog Store | **HOMECORE** | Status). **Complete, not a scaffold** (per the ADR's revised §2/§7): all **10 panels** ship fully built and rendered — §4.1 System Dashboard (v0 Appliance health strip + SEED fleet grid + ESP32 summary + COG status row + event-bus sparkline), §4.2 SEED Detail (vector store / witness chain / 5 onboard sensors / reflex rules / cognitive-fragility / ingest packet-type), §4.3 SEED Fleet Map (Appliance→SEED→ESP32 hierarchy, ESP-NOW mesh, cross-SEED fusion badges, ADR-105 federation), §4.4 Entity & State Browser (domain-grouped, **live WebSocket `subscribe_events` patching — never polls**, first-class provenance badges, keyword filter, context-causality slide-over), §4.5 RoomState/Sensing (mixture-of-specialists), §4.6 COG Management + App Registry, §4.7 Calibration Wizard (5-step baseline→enroll→train→verify), §4.8 Event Bus + Automation builder, §4.9 Witness/Audit log (two-tier SHA-256 + Ed25519 timeline, privacy-mode banner, pagination, export), §4.10 Settings. **Design system is the exact production Cognitum palette** (`tokens.css` carries `--cyan #4ecdc4` … `--r 10px` verbatim, §3.1) so there is no visual seam with the Cog Store (§3.3 invariant). **§6 UX invariants enforced in code and pinned by tests:** tier-origin provenance is always-visible (never collapsed); `stale`/`vetoed` flags and the kNN fragility score are prominent (amber/red tint + banners, never grey-on-grey); a `null` specialist renders "Not trained / calibrate to enable" **visually distinct from** veto-`withheld` (rendered as explicitly withheld, never zero) **distinct from** an error; all IDs/hashes/endpoints/payloads use `--mono`; Hailo-sourced COGs (`arch: hailo10`) are visually distinguished from CPU-only (`arch: arm`). **Wiring:** `homecore-server` gains a `--ui-dir`/`HOMECORE_UI_DIR` flag and mounts the assets via `tower-http` `ServeDir` at `/homecore` alongside the unchanged HA-compat `/api` surface (new testable `build_app()`), with **5 Rust integration tests** (`#[cfg(test)] mod ui_tests`, `tower::oneshot`) asserting index / design tokens / all-10-panels are served, the API coexists, and an empty `--ui-dir` disables the mount. **JS test + benchmark suite (`ui/`, runs under plain `node`, no npm install): 24 checks / 0 failed** — an import/export graph verifier (15 modules consistent), a DOM-shim render-smoke that *executes every panel* (21 checks: ui helpers + mock contracts + all 10 panels render without throwing), and an interaction suite (3 checks: live WS state-patch, ws.js handshake/parse, calibration backend contract). **Benchmark:** total bundle **136.8 KB uncompressed across 18 files — ~37× smaller than HA's ~5 MB Lit bundle** (the ADR-126 §1.1 foil), slowest panel **1.5 ms/cold-render**. **Honest scope (§7.1):** the live HOMECORE REST API (`/api/config|states|services`) and the WebSocket `subscribe_events` feed are driven for real; panels whose backing service is **not** in this binary (SEED HTTPS API, calibration ADR-151, ADR-105 federation) render against a **contract-conformant mock layer flagged with a DEMO banner** and swap to live the moment those endpoints land — no mock data is ever presented as real. **Not verified in this environment:** the Rust crate was edited and the integration tests written but **not compiled/run here** (no Rust toolchain present); `cargo test -p homecore-server` + `cargo build` must be run on a Rust host before merge.
 - **ADR-175: int8 quantization of the WiFlow-STD "half" pose model — MEASURED fp32-vs-int8 accuracy/size trade-off (honest negative).** Sub-deliverable 8.2 of the benchmark/optimization milestone, and the reading of the SOTA brief's "one untested edge lever" (QAT-int8 on the 843,834-param half model that strictly dominates the published 2.23M model). A new committed script `v2/crates/wifi-densepose-train/scripts/quantize_half_int8.py` quantizes `half_best.pth` to int8 two ways and scores both with the **same** upstream `calculate_pck`/`calculate_mpjpe` that produced the fp32 sweep numbers, under **one locked normalization** (ADR-173 torso-diameter PCK — neck idx2→pelvis idx12, `use_torso_norm=True`, the standard MM-Fi/GraphPose-Fi convention), on the **same** seed-42 file-level 70/15/15 test split (52,560 NaN-free / 54,000 full windows). **MEASURED on ruvultra (RTX 5080, torch 2.11.0+cu128, fbgemm; clean test, torso-PCK):** fp32 = 96.62% PCK@20 / 99.47% PCK@50 / 0.008981 MPJPE / 3.351 MB (fp32-CPU reproduces fp32-GPU to 4 dp, so the int8 deltas are pure quantization, not CPU/GPU drift); **int8 static PTQ = 40.98% PCK@20 (−55.64 pp), 1.046 MB** — naive static QDQ **collapses** on this model (the brief's 2.23M "sweet spot" does NOT transfer to the 843k half model at the tight @20 threshold); **int8 QAT (3-epoch FX fake-quant fine-tune from half_best) = 67.48% PCK@20 (−29.15 pp) / 98.69% PCK@50 (−0.78 pp), 1.043 MB.** **Verdict (honest no):** int8 is **not a win** at the strict PCK@20 edge target — QAT recovers a large share of the PTQ collapse and is near-lossless at the loose PCK@50 (coarse localization survives int8, fine does not), but a **3.2× size win at −29 pp PCK@20** is a bad trade when the half model already fits edge flash at fp32 → **keep fp32/fp16 on the edge for now.** **Disclosed gap:** the QAT *fake-quant* val PCK@20 reached 83.45% but the *converted* int8 model scores 67.48% — a real ~16 pp `convert_fx` gap (fbgemm int8 kernels ≠ straight-through estimate, esp. the axial-attention einsum/softmax); we report the converted-int8 number, not the fake-quant proxy. **MEASURED:** every table number + the PTQ collapse + the QAT partial recovery + the conversion gap. **CLAIMED/not done:** ONNX/TFLite export, on-edge-SoC latency/energy (int8 measured on x86 fbgemm — size transfers, latency does NOT), mixed-precision keeping attention fp32, longer/better-tuned QAT. **Honest limitations:** single in-domain eval split (no cross-environment split), x86-int8 not edge-SoC-int8, lightly-tuned QAT. Additive only — no production Rust or signal-pipeline change; Python deterministic proof unchanged (`f8e76f21…46f7a`, bit-exact — off the signal proof path).

+# ADR-263: Adopt RTL8720F 2.4 GHz FMCW radar as an optional RuView sensing platform
+
+- **Status**: proposed
+- **Date**: 2026-07-18
+- **Deciders**: ruv
+- **Tags**: realtek, rtl8720f, ameba, fmcw, radar, cfr, csi, hardware
+- **Relates to**: ADR-018, ADR-063, ADR-064, ADR-095, ADR-097, ADR-260, ADR-262
+
+## Context
+
+Realtek's `RTL8720F-2.4G-Radar-Advantages_EN.pptx` describes an RTL8720F mode that shares the
+2.4 GHz radio between Wi-Fi, Bluetooth, and an active FMCW radar. It offers two data products that
+are useful to RuView:
+
+1. **CFR (Channel Frequency Report)**, described by Realtek as the same concept as Wi-Fi CSI.
+2. **Near and far Range-FFT reports**, preserving near-field content while extending observation to
+   approximately 5–6 m.
+
+The proposed radio uses one transmit and one receive antenna, 20/40/70 MHz sweeps, configurable
+8/16/32/64 microsecond chirp symbols, a maximum 2.56 ms FMCW packet, and a configurable frame
+interval above 15 ms. The deck recommends 40 MHz outside Japan and 20 MHz in Japan. It also
+describes EDCCA/CTS channel access, Wi-Fi/BT/radar time division, interference reporting, and
+priority arbitration in the driver.
+
+This is not a drop-in replacement for ESP32 CSI:
+
+- it is **active monostatic FMCW**, while the ESP32 path observes Wi-Fi packet CSI;
+- one Tx/one Rx has no angle-of-arrival or native multi-target separation;
+- the stated 40 MHz range resolution is about 3.15 m, despite a finer 0.59 m Range-FFT report step;
+- the presentation is a capability description, not an SDK contract. It contains no header names,
+  function signatures, callback ABI, binary layouts, toolchain version, licensing terms, or public
+  RTL8720F board package.
+
+Realtek's public Ameba RTOS repository is the base. Release v1.2.1 includes the CSI API and fixes a
+CSI application-buffer semaphore issue, but does not expose the radar application surface. Open
+upstream PR #1336 (2026-07-18 snapshot) adds RTL8720F project artifacts, `AT+RAD`, `AT+RADDBG`, and
+the public configuration call `wifi_radar_config(struct rtw_radar_action_parm *)`. Its public
+parameter struct confirms mode, channel, 70/40/20 MHz bandwidth selector, trigger period, and
+enable/config actions. Report reception still crosses non-public/placeholder HAL symbols such as
+`wifi_hal_radar_recv_data(frame_num, frame_type, data)`, so the report layout and buffer lifetime
+remain vendor-gated. Therefore the integration stays split at that boundary.
+
+## Decision
+
+RuView will support RTL8720F radar as an **optional, capability-negotiated source**, without
+replacing the ESP32 firmware or treating radar CFR as byte-compatible with ADR-018 CSI.
+
+The integration has three layers:
+
+1. **Realtek device firmware**: a small application built in the vendor-supported Ameba SDK calls
+   the radar API, owns coexistence configuration, and emits versioned reports. This code lives under
+   `firmware/rtl8720f-radar/` only after the redistributable SDK/API is available.
+2. **Transport-neutral wire contract**: CFR and Range-FFT reports are framed independently from the
+   vendor ABI and sent over UDP, USB CDC, or UART. ADR-264 defines this boundary.
+3. **Rust host adapter**: `wifi-densepose-hardware` parses reports from bytes and converts CFR into
+   the existing CSI-domain representation, while Range-FFT remains a radar modality and feeds the
+   RuField/RuView cross-modality bridge from ADR-260/262.
+
+The two report types remain semantically distinct:
+
+| RTL8720F output | RuView representation | Permitted use |
+|---|---|---|
+| CFR | `CsiFrame` through a Realtek calibration adapter | CSI feature extraction after validation |
+| Range-FFT near/far | `RadarFrame` / RuField `mmwave_radar`-class event with a 2.4 GHz descriptor | range, motion, presence, fusion |
+| Vendor AI presence probability | derived observation with model/version provenance | advisory input, never ground truth |
+| Interference report | quality/provenance metadata | reject, down-weight, or mark contaminated frames |
+
+The modality registry should eventually distinguish `fmcw_radar_2_4ghz` from `mmwave_radar`; until
+that RuField schema revision is accepted, the adapter must attach `carrier_hz = 2.4e9` and must not
+claim millimetre-wave provenance.
+
+## Delivery phases and gates
+
+### P0 — Vendor enablement
+
+Obtain the PR #1336-or-newer RTL8720F SDK package, radar API headers/libraries, a supported evaluation
+board, flashing/debug instructions, report definitions, and written redistribution terms.
+
+**Gate:** compile and run Realtek's unmodified radar example and capture CFR plus near/far
+Range-FFT output. Until this passes, device firmware is `VENDOR_BLOCKED`, not implemented.
+
+### P1 — Host-first contract
+
+Implement ADR-264 types, parsers, fixtures, fuzz tests, and replay support without linking vendor
+code. Use the Rust `Rtl8720fSimulator` as the only pre-hardware live source. It emits deterministic
+CFR, near/far Range-FFT, interference, and capabilities frames through the same ADR-264 encoder and
+parser used by hardware. Every simulated frame sets `RadarFlags::SYNTHETIC`; simulation results are
+never reported as device measurements.
+
+**Gate:** malformed inputs never panic; encode/decode round trips; unknown versions and report
+types fail closed.
+
+### P2 — RTL8720F firmware adapter
+
+Wrap only the minimum vendor API surface: initialization, profile configuration, start/stop,
+callback acquisition, interference status, and report serialization. Keep vendor types out of the
+wire protocol.
+
+**Gate:** 30-minute simultaneous Wi-Fi telemetry and radar capture with no watchdog reset, bounded
+loss, monotonic sequence numbers, and explicit coexistence/interference statistics.
+
+### P3 — Calibration and signal validation
+
+Calibrate CFR phase/amplitude, Range-FFT bin spacing, static leakage, and clock drift. Compare
+reported range against measured targets at multiple distances and bandwidths.
+
+**Gate:** publish measured error distributions. Do not infer accuracy from report-bin spacing and
+do not advertise multi-person pose or vital signs from the vendor deck.
+
+### P4 — Fusion and productization
+
+Feed calibrated CFR through the CSI path and Range-FFT through RuField, retaining source, mode,
+bandwidth, calibration, firmware, and interference provenance.
+
+**Gate:** ablation shows whether the radar stream improves a named RuView metric over ESP32 CSI
+alone. If it does not, ship it only as an independent presence/range sensor.
+
+## Consequences
+
+### Positive
+
+- One low-cost radio can provide active radar and CSI-like CFR while retaining Wi-Fi connectivity.
+- Range-FFT adds an independent physical measurement for presence/range fusion.
+- The vendor SDK is isolated from the Rust sensing core and from the stable on-wire contract.
+- Capability negotiation permits future Realtek parts without another application-level fork.
+
+### Negative
+
+- The first implementation is blocked on access to the actual RTL8720F radar SDK/API and hardware.
+- Active 2.4 GHz transmission changes coexistence, privacy, power, and regional compliance concerns.
+- 1T1R and limited sweep bandwidth cannot provide the spatial resolution of multi-antenna mmWave.
+- A second embedded toolchain and firmware release process must be maintained.
+
+### Neutral
+
+- ESP32 remains the default CSI node.
+- Existing consumers receive normalized frames and do not link against Realtek code.
+- Vendor AI output is optional metadata; RuView retains responsibility for its own validation.
+
+## Rejected alternatives
+
+1. **Map Range-FFT directly to `CsiFrame`.** Rejected because range bins and channel-frequency
+   samples have different axes and physical meaning.
+2. **Link the Realtek SDK into the Rust server.** Rejected because it couples host builds to a
+   proprietary embedded ABI and toolchain.
+3. **Wait to define any interface until hardware arrives.** Rejected because the host protocol,
+   parser safety, replay, and provenance can be developed and reviewed independently.
+4. **Replace ESP32 nodes.** Rejected because the modes are complementary and availability differs.
+
+## Open vendor questions
+
+- Exact RTL8720F part/board identifier and production availability.
+- SDK repository/tag, compiler, RTOS, binary blobs, license, and redistribution permissions.
+- Radar initialization/configuration/callback API signatures and threading/ISR constraints.
+- CFR and near/far Range-FFT element type, complex ordering, scaling, endianness, and timestamps.
+- Whether CFR is calibrated complex data and whether phase remains coherent across frames.
+- Maximum report rates, buffer ownership, DMA/cache constraints, and Wi-Fi throughput impact.
+- Region/channel enforcement and whether 70 MHz operation is allowed by the supplied firmware.
+- Secure boot, signed OTA, unique device identity, and firmware attestation support.
+
+## Sources
+

+  supplied 2026-07-18. This is product material, not measured RuView validation.
+- [Ameba-AIoT/ameba-rtos releases](https://github.com/Ameba-AIoT/ameba-rtos/releases), reviewed

+
+## Context
+
+ADR-182 minted and published **`@ruvnet/ruview@0.1.0`** (`harness/ruview/`) — the
+`npx ruview` operator harness: a dependency-free ESM CLI + minimal MCP stdio server
+exposing six `ruview.*` tools (onboard / claim_check / verify / node_monitor /
+calibrate / node_flash), five skill playbooks, and the executable
+MEASURED-vs-CLAIMED guardrail (`src/guardrails.js`). The package is live on npm
+(0.1.0, 49.5 kB unpacked / 21 files — MEASURED, `npm view @ruvnet/ruview` +
+`npm pack --dry-run`) and is the recommended MCP registration path
+(`npx -y @ruvnet/ruview mcp start` in the bundled `.claude/settings.json`).
+
+This ADR is the first dedicated deep review of that npm artifact: correctness,
+fail-open/fail-closed posture, performance (cold start + request handling),
+packaging hygiene, and security of the subprocess surface. All 17 bundled tests
+pass on Node 22 (MEASURED, `node --test test/*.test.mjs`, 17/17, ~108 ms).
+
+## Findings
+
+Severity reflects impact on the package's stated contract: *fail-closed operator
+tools + an honesty guardrail that must never fail open*.
+
+### F1 (HIGH, fail-open): `claim-check` passes silently on empty input
+
+`bin/cli.js` `claim-check` with **neither `--text` nor `--file`** sends
+`text: undefined` → `claimCheck(String(args.text ?? ''))` → `''` → `ok: true`,
+**exit 0**. A CI hook wired as `npx ruview claim-check --text "$BODY"` where
+`$BODY` expands empty therefore reports PASS. This is the single tool whose whole
+purpose is to fail closed; empty input must be an error, not a pass.
+Reproducer: `node bin/cli.js claim-check` → `{"ok": true}`, exit 0.
+
+### F2 (HIGH, head-of-line blocking): MCP server is fully synchronous
+
+`src/mcp-server.js` dispatches `tools/call` inside the readline `line` handler,
+and every heavyweight handler in `src/tools.js` uses **`spawnSync`**
+(`ruview.verify` up to 180 s, `ruview.calibrate` up to 300–600 s,
+`ruview.node_monitor` up to `seconds+10`). While one call runs, the event loop is
+blocked: `ping`, `tools/list`, and concurrent `tools/call` requests are not even
+read from stdin. Hosts that health-check with `ping` during a long `calibrate`
+will conclude the server is dead and kill it mid-run.
+
+### F3 (MEDIUM, cold start): optionalDependencies triple the `npx` install for a path that never uses them
+
+`package.json` declares `optionalDependencies` on `@metaharness/kernel` and
+`@metaharness/host-claude-code`. npm installs optional deps **by default**, so
+every cold `npx -y @ruvnet/ruview mcp start` fetches 3 extra packages (kernel +
+host + transitive `@ruvector/emergent-time`). MEASURED (npm 10.9.7, this
+container): default install = **4 packages, 620 kB, 71 files**; with
+`--omit=optional` = **1 package, 172 kB, 22 files**. The operator-tool and MCP
+paths never import these — only `doctor`/`install` do, and both already
+dynamic-import inside `try/catch` and degrade gracefully when absent
+(`kernel/host: not installed (ok…)`). The optional deps buy nothing on the hot
+path and cost 3 registry round-trips + ~450 kB on every cold start.
+
+### F4 (MEDIUM, silent truncation): `spawnSync` default `maxBuffer` (1 MiB)
+
+`run()` in `src/tools.js` never sets `maxBuffer`. `cargo run -p
+wifi-densepose-cli` (the `calibrate` fallback path) and a chatty `verify.py` can
+exceed 1 MiB of stdout, at which point the child is killed with `ENOBUFS` and the
+tool reports a spawn error that looks like a proof/calibration failure. The
+handlers only ever consume the last 8 kB/1.5 kB; buffering should be bounded but
+generous (e.g. `maxBuffer: 16 MiB`) or streamed with a tail ring.
+
+### F5 (MEDIUM, injection surface): `node_monitor` interpolates the port into Python source
+
+The handler builds a `python -c` script by string interpolation:
+`` `ser=serial.Serial(${JSON.stringify(port)},115200,…)` `` and
+`` `while time.time()-t<${dur}:` ``. `JSON.stringify` produces a *JavaScript*
+string literal; Python string-literal semantics differ at the edges (`\uXXXX` is
+shared, but e.g. JS emits raw U+2028/U+2029 unescaped pre-ES2019 rules aside, and
+any future non-JSON-safe field added the same way would be executable). `port`
+arrives from the MCP caller (an agent), so this is an agent-controlled string
+concatenated into an interpreter invocation. `dur` is `Number()`-guarded; `port`
+should be passed out-of-band (`sys.argv`/env), never spliced into source.
+
+### F6 (LOW, drift): server version hardcoded
+
+`SERVER_INFO = { name: 'ruview', version: '0.1.0' }` in `src/mcp-server.js`
+duplicates `package.json.version` (the CLI's `--version` already reads
+package.json at runtime). First release bump will drift the MCP handshake
+version.
+
+### F7 (LOW, duplication): every skill ships twice
+
+`skills/*.md` and `.claude/skills/*/SKILL.md` are byte-identical (same sha256 in
+`.harness/manifest.json`). ~8 kB of the 49.5 kB unpacked payload is duplicate
+content, and — worse than size — two copies must be kept in sync by hand.
+
+### F8 (LOW, perf + portability): `which()` is uncached and shells out
+
+`which()` runs up to twice per tool call (`python` then `python3`), each a
+blocking `spawnSync`; the POSIX branch spawns a shell (`shell: true`). Results
+are stable for the process lifetime and should be memoized; the lookup can be
+done dep-free with a PATH scan instead of a shell.
+
+### F9 (LOW, interop): dot-named tools + minimal protocol surface
+
+Tool names (`ruview.onboard`, `ruview.claim_check`, …) contain dots. MCP itself
+does not restrict names, but downstream host APIs commonly enforce
+`^[a-zA-Z0-9_-]{1,64}$` for tool names; hosts must then sanitize or reject.
+The server also answers `resources/list` / `prompts/list` with `-32601` (it does
+not advertise those capabilities, so this is spec-legal, but empty-list stubs are
+cheaper than every host's error path). Protocol version is pinned to
+`2024-11-05` with no negotiation fallback. None of this breaks Claude Code today;
+it narrows portability, which is the harness's whole pitch (9 hosts, ADR-182).
+
+### F10 (LOW, CI gap): the published package has zero CI
+
+No workflow under `.github/workflows/` runs `harness/ruview` tests (checked:
+no workflow references `harness/ruview`, `ruview-mcp`, or `ruview-cli`), and
+`ci.yml` pins `NODE_VERSION: '18'` while the package declares
+`engines.node >= 20`. Note also `node --test test/` (directory form) fails on
+Node 22 while the documented glob form passes — CI should pin the working
+invocation. Consolidated CI/publish strategy is ADR-265.
+
+### F11 (MEDIUM, guardrail precision): `METRIC_TERMS` substring matching false-positives on ordinary prose
+
+Found by dogfooding this review: `claimCheck` matches metric terms with
+`lower.includes(t)`, so the two-character terms `'map'` and `'f1'` fire inside
+ordinary words and labels — "source **map**s", "the **map**s can never
+resolve", finding IDs like "**F1** (HIGH…)". MEASURED reproducer: running
+`npx ruview claim-check --file` over this ADR and ADR-264 yields 4 and 16
+medium findings respectively, the majority of which are `map`/`F1`
+false positives on lines carrying no accuracy claim. A guardrail that cries
+wolf trains people to ignore it — precision is part of its fail-closed
+contract. Short/ambiguous terms need word-boundary matching (`\bmap\b`,
+`\bf1\b`, likewise `auc`, `iou`), and section-heading label patterns
+(`F\d+`, `O\d+`) should not count as metric mentions.
+
+## Decision
+
+Adopt the following optimization strategy, in priority order. Each item is
+independently shippable; F-numbers map to findings.
+
+- **O1 (F1):** `claim-check` with no `--text`/`--file` (or empty text after read)
+  exits 2 with a usage error. Add a regression test pinning exit ≠ 0.
+- **O2 (F2):** make the MCP dispatch async: convert `run()`/`which()` to
+  promise-based `spawn`, make `tools/call` handlers `async`, and keep reading
+  stdin while calls run (respond to `ping`/`tools/list` concurrently; serialize
+  only same-tool hardware operations). Acceptance: `ping` round-trips < 50 ms
+  while a synthetic 30 s `calibrate` is in flight.
+- **O3 (F3):** drop the two `optionalDependencies`; `doctor`/`install` already
+  degrade and should print the exact `npm i @metaharness/kernel
+  @metaharness/host-claude-code` hint on the miss path. Acceptance: cold
+  `npm i @ruvnet/ruview` installs exactly 1 package (MEASURED baseline above).
+- **O4 (F4):** set `maxBuffer: 16 * 1024 * 1024` in `run()` (or stream + tail).
+- **O5 (F5):** pass `port` to the monitor script via `sys.argv`
+  (`python -c script -- <port>`), never by source interpolation.
+- **O6 (F6):** read the MCP `serverInfo.version` from `package.json` once at
+  startup (same pattern the CLI already uses).
+- **O7 (F7):** make `skills/*.md` the single source and generate
+  `.claude/skills/*/SKILL.md` in a `prepack` script (or vice versa); manifest
+  hashes then pin one canonical set.
+- **O8 (F8, F9):** memoize `which()`; add underscore aliases for the dot-named
+  tools (accept both in `tools/call`, advertise the underscore form) and add
+  empty `resources/list` / `prompts/list` stubs.
+- **O9 (F11):** switch `METRIC_TERMS` matching to word-boundary regexes for
+  short terms (`map`, `f1`, `auc`, `iou`) and skip label tokens matching
+  `\b[FO]\d+\b`. Acceptance: `claim-check --file` over ADR-263/264/265 reports
+  only the genuinely tagged-or-taggable percentage lines, and the existing 17
+  guardrail tests still pass plus new false-positive pins ("source maps",
+  "F1 (HIGH)" → no finding).
+
+Non-goals: no new runtime dependencies (the zero-dep MCP server is a feature,
+not an accident — keep it), no build step, no change to the fail-closed tool
+contracts.
+
+## Consequences
+
+- The honesty guardrail becomes fail-closed end-to-end (its current empty-input
+  pass is the exact failure mode the guardrail exists to prevent).
+- `npx` cold start drops ~450 kB / 3 packages (MEASURED baseline in F3) with no
+  feature loss; `doctor` output already communicates the optional-dep story.
+- Long-running `verify`/`calibrate` no longer starve the MCP channel — the
+  harness survives host health checks during real calibration runs.
+- Two-copy skill drift becomes impossible at pack time.
+- Costs: async conversion touches every handler signature in `src/tools.js`
+  (mechanical, ~6 handlers); alias tools add a small compatibility table.
+- Verification for the implementing PR: bundled tests extended for O1/O2/O5
+  (target ≥ 20 tests), `npm pack --dry-run` file-count asserted, and the F3
+  install measurement re-run and quoted MEASURED in the PR body — which must
+  itself pass `npx ruview claim-check`.

+# ADR-264: Versioned wire protocol for RTL8720F CFR and Range-FFT reports
+
+- **Status**: proposed
+- **Date**: 2026-07-18
+- **Deciders**: ruv
+- **Tags**: realtek, rtl8720f, protocol, cfr, range-fft, udp, serial
+- **Depends on**: ADR-263
+- **Relates to**: ADR-018, ADR-095, ADR-097, ADR-099, ADR-260
+
+## Context
+
+ADR-263 adopts RTL8720F radar behind an anti-corruption boundary. The Realtek presentation names
+CFR, near Range-FFT, far Range-FFT, and interference reports, but does not specify their binary ABI.
+RuView needs a stable, testable contract that can be implemented before the vendor SDK arrives and
+that will not expose vendor structs, pointer layouts, padding, or callback lifetime rules over the
+network.
+
+ADR-018 already defines ESP32 CSI framing. Reusing its magic or pretending that Realtek radar is an
+ESP32 packet would make source detection ambiguous and erase radar-specific calibration metadata.
+
+## Decision
+
+Define a new little-endian `RtlRadarFrameV1` envelope with its own magic and explicit payload type.
+This is a RuView protocol, not a claim about Realtek's native memory layout.
+
+### Envelope
+
+All integer fields are little-endian. Floating-point payloads use IEEE-754 binary32. No C struct is
+sent by `memcpy`; firmware serializes each field explicitly.
+
+| Offset | Size | Field | Meaning |
+|---:|---:|---|---|
+| 0 | 4 | magic | ASCII `RTR1` (`0x31525452`) |
+| 4 | 1 | version | `1` |
+| 5 | 1 | report_type | 1 CFR, 2 range-near, 3 range-far, 4 interference, 5 capabilities |
+| 6 | 2 | header_len | complete header size, initially 56 |
+| 8 | 4 | frame_len | header + payload + CRC |
+| 12 | 4 | sequence | wraps modulo 2^32 |
+| 16 | 8 | timestamp_us | monotonic device time at acquisition |
+| 24 | 8 | device_id | stable pseudonymous identifier, not a MAC address |
+| 32 | 4 | center_freq_khz | RF centre frequency |
+| 36 | 2 | bandwidth_mhz | 20, 40, or 70 |
+| 38 | 2 | flags | calibration/interference/saturation/time-sync flags |
+| 40 | 2 | element_count | complex samples or range bins |
+| 42 | 1 | element_format | 0 bytes/TLV, 1 complex-i16, 2 complex-f32, 3 power-u16, 4 power-f32 |
+| 43 | 1 | antenna_count | expected to be 1 for the deck's 1T1R configuration |
+| 44 | 4 | scale | quantized-to-physical multiplier; `1.0` for float payloads |
+| 48 | 4 | bin_spacing | Hz for CFR, metres for Range-FFT |
+| 52 | 4 | calibration_id | device calibration revision/hash prefix |
+| 56 | variable | payload | determined by type, count, and format |
+| final-4 | 4 | crc32 | IEEE CRC-32 over header and payload |
+
+If vendor evidence shows that 56 bytes is too costly, a later protocol version may introduce a
+compact header. V1 favors auditable provenance over premature byte savings.
+
+### Payload semantics
+
+- **CFR** contains ordered complex channel-frequency samples. The adapter must know the frequency
+  origin/order and must not fabricate missing phase. Uncalibrated frames carry the uncalibrated flag
+  and cannot enter phase-sensitive processing.
+- **Range-near/range-far** contains ordered range bins. Near and far are separate report types so
+  filtering and leakage behavior are never hidden from consumers.
+- **Interference** contains a versioned TLV set for channel-busy, detected-during-chirp, estimated
+  interference power, and packet jitter. Unknown TLVs are skipped by length.
+- **Capabilities** is emitted at boot and on request. It declares supported report types, bandwidths,
+  chirp lengths, maximum elements/report, maximum frame rate, firmware version, and SDK identifier.
+
+### Transport
+
+The identical envelope is supported over:
+
+- UDP datagrams for normal RuView ingestion;
+- USB CDC or UART with COBS framing and a zero-byte delimiter;
+- file replay as a length-prefixed sequence of envelopes.
+
+One envelope must fit one UDP datagram. Fragmentation is not part of V1; firmware rejects a profile
+whose maximum report exceeds the configured MTU and reports the required size through capabilities.
+
+### Parser and trust rules
+
+The host parser:
+
+1. validates magic, version, lengths, enum values, element count/format multiplication, and CRC
+   before allocating or decoding the payload;
+2. caps frames at 64 KiB and elements at a configured hardware maximum;
+3. rejects non-finite float metadata/payload values;
+4. tracks sequence gaps and timestamp regressions per device;
+5. preserves unknown flags but never interprets them as trusted;
+6. attaches transport source, firmware/SDK version, calibration ID, and interference state to
+   provenance;
+7. labels fixture/generated frames as synthetic.
+
+No vendor-provided presence probability bypasses RuView privacy, provenance, or quality gates.
+
+## Consequences
+
+### Positive
+
+- Firmware, transport, parser, replay, and fusion can evolve independently.
+- Fuzzing and golden fixtures require no Realtek SDK or board.
+- CFR and Range-FFT retain correct axes and calibration provenance.
+- A boot-time capabilities frame makes SDK/API drift observable.
+
+### Negative
+
+- Serialization adds CPU and bandwidth overhead compared with dumping a vendor buffer.
+- V1 fields may need revision after the actual API and report limits are disclosed.
+- UDP provides integrity/error detection, not authenticity or confidentiality.
+
+### Neutral
+
+- Authentication can be layered with ADR-032 device identity or a signed RuField receipt without
+  changing report semantics.
+- ESP32 ADR-018 framing remains unchanged.
+
+## Implementation plan
+
+1. Add `rtl8720f` types/parser module to `wifi-densepose-hardware` behind no vendor dependency.
+2. Add golden CFR, near/far Range-FFT, interference, and capabilities fixtures.
+3. Add property/fuzz tests for length arithmetic, enum handling, CRC, and float validation.
+4. Add a replay CLI that prints normalized metadata without running inference.
+5. Once SDK access exists, implement the embedded serializer and verify captured frames against the
+   host golden decoder.
+6. Revise this proposed ADR with measured element counts, rates, and API names before acceptance.
+
+Host-side steps 1–3 are implemented in `wifi-densepose-hardware::rtl8720f`: typed report and
+element enums, semantic type/format validation, bounded length arithmetic, CRC verification,
+finite-float checks, encode/decode round trips, corruption/truncation tests, and deterministic
+arbitrary-input panic checks. Cross-language vectors remain blocked on the vendor SDK callback ABI.
+Bit 15 of `flags` is reserved by RuView as `SYNTHETIC`; the Rust simulator always sets it and real
+firmware must never set it. The simulator is deterministic by seed and exercises the production
+encoder/parser rather than a parallel mock representation.
+
+## Acceptance criteria
+
+- Rust encode/decode round-trip for every report type.
+- Cross-language golden vector produced by the RTL8720F firmware.
+- Zero parser panics over the fuzz corpus and arbitrary byte input.
+- Detection of single-bit corruption, truncation, count overflow, timestamp regression, and gaps.
+- Captured CFR frequency order and Range-FFT bin spacing verified against vendor documentation and a
+  measured target.
+
+## Sources
+
+- Realtek Semiconductor, `RTL8720F-2.4G-Radar-Advantages_EN.pptx`, slides 11–19, supplied
+  2026-07-18.
+- ADR-018 (ESP32 framing), ADR-095/097 (hardware normalization), ADR-260 (multimodal event model),
+  and ADR-263 (platform decision).

+| **Deciders** | ruv |
+| **Codename** | **RUVIEW-NPM-REVIEW-2** |
+| **Supersedes / amends** | none (reviews the ADR-104/ADR-124 artifacts; feeds ADR-265 distribution strategy) |
+
+## Context
+
+Two TypeScript npm packages expose RuView sensing to agents and shells:
+
+- **`@ruvnet/rvagent@0.1.0`** (`tools/ruview-mcp/`) — SENSE-BRIDGE, the MCP
+  server over the sensing-server HTTP API + cog binaries: 12 tools
+  (csi/pose/count/registry/train/job + ADR-124 BFLD/presence/vitals). Published
+  (188 kB unpacked — MEASURED, `npm view @ruvnet/rvagent`). Deps:
+  `@modelcontextprotocol/sdk` + `zod`.
+- **`@ruv/ruview-cli@0.0.1`** (`tools/ruview-cli/`) — `private: true` yargs CLI
+  mirroring the same capabilities; intentionally duplicates `http.ts`/`cog.ts`/
+  `config.ts` (~150 lines) to stay standalone.
+
+This ADR records a deep review of both: packaging correctness (verified against
+the **published** tarball, not just the source tree), protocol/interop, resource
+lifecycle, and the honesty of the package's own self-description — the same
+MEASURED-vs-CLAIMED bar the project applies to accuracy numbers.
+
+## Findings
+
+### F1 (HIGH, broken export): `require` condition points at a file that does not exist
+
+`package.json` `exports["."].require = "./dist/index.cjs"`, but the build is
+plain `tsc` (ESM only) and **the published 0.1.0 tarball contains no
+`index.cjs`** (verified by listing the registry tarball). Any CJS consumer doing
+`require('@ruvnet/rvagent')` resolves to a nonexistent file →
+`ERR_MODULE_NOT_FOUND`. Additionally the `types` condition is listed **after**
+`import`/`require`; TypeScript requires `types` first or it may be ignored under
+`moduleResolution: bundler/node16`.
+
+### F2 (MEDIUM, tarball bloat): a third of the published package is dead source maps
+
+The 0.1.0 tarball ships **44 `.map` files = 62,698 B** against 78,209 B of
+actual `.js` (MEASURED, extracted registry tarball). `src/` is not published, so
+every `sourceMappingURL` points at `../src/*.ts` that consumers do not have —
+the maps can never resolve. Also `files` lists `CHANGELOG.md`, which does not
+exist in `tools/ruview-mcp/` (npm silently skips it), so the advertised file set
+is partly fictional.
+
+### F3 (MEDIUM, honesty): the package description claims a transport it does not start
+
+The description reads "**dual-transport MCP server (stdio + Streamable HTTP)**",
+but `main()` in `src/index.ts` wires **stdio only**. `http-transport.ts` is a
+complete, tested scaffold that nothing imports at runtime — there is no flag,
+env var, or subcommand that starts it. By this project's own rule this is a
+CLAIMED capability presented as shipped. Either wire it (`--http` /
+`RVAGENT_HTTP_PORT` gate) or de-claim the description until it is.
+
+### F4 (MEDIUM, interop + inconsistency): two tool-naming conventions, one of them dot-based
+
+Six tools use `ruview_snake_case`; six (ADR-124 additions) use
+`ruview.dotted.names`. Same interop caveat as ADR-263 F9 (host tool-name
+regexes commonly `^[a-zA-Z0-9_-]{1,64}$`), plus the split convention makes the
+tool surface look like two products. Standardize on underscores and accept the
+dotted forms as aliases for one deprecation cycle.
+
+### F5 (MEDIUM, double work + drift): every tool input is validated twice from two hand-maintained schemas
+
+`CallToolRequestSchema` handler runs `TOOL_INPUT_SCHEMAS[name].safeParse(args)`,
+then each tool handler runs its own `schema.parse(args)` again — two full Zod
+passes per call. Separately, the `inputSchema` JSON advertised via `tools/list`
+is **hand-written** and duplicates the Zod schema field-by-field (defaults,
+min/max, descriptions) — schema drift between what is advertised and what is
+enforced is a matter of time. Parse once at the gate, pass the typed result to
+handlers, and generate the advertised JSON Schema from the Zod source
+(`zod-to-json-schema` at build time, or Zod 4's native `z.toJSONSchema` when the
+SDK's peer range allows).
+
+### F6 (MEDIUM, resource lifecycle): `train_count` leaks 2 fds per job; job registry is process-local
+
+`trainCount` opens `logFdOut`/`logFdErr` with `openSync` and never closes them
+in the parent — the spawned cargo child inherits duplicates, but the parent's
+descriptors stay open for the MCP server's lifetime: 2 leaked fds per training
+job. `jobRegistry` is an in-memory `Map`, so `ruview_job_status` after a server
+restart reports "not found" for a training run that is still burning GPU (the
+source comments acknowledge this; the fix — persist `~/.ruview/jobs/<id>.json`,
+already the documented layout — is small). Also `jobStatus` re-`import`s
+`node:fs` on every poll and reads the entire log to return 20 lines.
+
+### F7 (MEDIUM, security/robustness of the HTTP scaffold): unbounded body + one shared session transport
+
+`http-transport.ts` buffers the request body with no size cap (memory DoS the
+moment it is wired to a socket), reuses a **single**
+`StreamableHTTPServerTransport` with `sessionIdGenerator` for all clients (the
+SDK's stateful mode expects one transport per session — a second client's
+`initialize` collides), and the Origin allowlist is exact-match
+(`http://localhost` will not match a real browser origin `http://localhost:5173`).
+Must be fixed **before** F3 wires it in; bearer-token + 127.0.0.1 defaults are
+already right.
+
+### F8 (LOW, dead/misleading code): `detectCogBinary` always returns the bare name
+
+It builds a 4-candidate appliance-path array and then returns
+`candidates[candidates.length - 1]` — i.e. always `name` — without checking
+existence. The candidates are dead weight that reads as if path detection
+happens. Either probe with `existsSync` or delete the array.
+
+### F9 (LOW, drift + hygiene): hardcoded versions, unused/mismatched devDeps, bin-name collision
+
+`PACKAGE_VERSION = "0.1.0"` (index.ts) duplicates package.json;
+`@types/express` is unused (`http-transport` uses `node:http`); `@types/jest@30`
+against `jest@29`; `ruview-cli` hardcodes `.version("0.0.1")`. And
+`@ruv/ruview-cli` claims the **`ruview`** bin name, which collides with
+`@ruvnet/ruview`'s bin (ADR-182) if both are ever installed globally —
+ADR-263/265 give the `ruview` name to the harness; the CLI must rename or fold.
+
+## Decision
+
+- **O1 (F1):** fix `exports`: drop the `require` condition (ESM-only is fine for
+  a bin-first package) or add a real CJS build; put `types` first. Add a CI
+  smoke test that does `npm pack` + `node -e "import('<tarball install>')"`.
+- **O2 (F2):** publish without maps: `declarationMap: false`, `sourceMap: false`
+  in a `tsconfig.build.json` used by `prepack` (or add `!dist/**/*.map` to
+  `files`). Remove the phantom `CHANGELOG.md` entry or create the file.
+  Acceptance: unpacked size ≤ ~125 kB (from 188 kB — MEASURED, `npm pack --dry-run`).
+- **O3 (F3, F7):** wire the HTTP transport behind an explicit opt-in
+  (`RVAGENT_HTTP_PORT` or `--http`), after F7 fixes: per-session transport map
+  keyed by `mcp-session-id`, 1 MiB body cap, origin matching that honors ports
+  (compare `URL.origin` prefixes or document exact origins). Until then, change
+  the description to "stdio MCP server (Streamable HTTP scaffold, unwired)".
+- **O4 (F4):** rename dotted tools to underscore (`ruview_bfld_last_scan`, …),
+  keep dotted aliases in the call router for one release, note it in the README.
+- **O5 (F5):** single validation gate: the registry maps name → Zod schema →
+  typed handler; advertised `inputSchema` generated from Zod at build time.
+- **O6 (F6):** close parent fds after spawn (`closeSync` post-`spawn` — the
+  child holds its own copies), persist job records to
+  `<jobsDir>/<id>.json`, and read log tails with a bounded read.
+- **O7 (F8):** make `detectCogBinary` actually probe (`existsSync` over the
+  candidates) — it is the entire reason the function exists.
+- **O8 (F9):** single-source versions from package.json; drop `@types/express`;
+  align `@types/jest` with jest 29 (or move to `node:test` like the harness and
+  drop the jest toolchain entirely — it is the heaviest devDep in both
+  packages).
+- **O9 (F9, scope):** fold `@ruv/ruview-cli` into `rvagent` as a second bin
+  (`rvagent-cli`) sharing `http/cog/config`, or keep it private-forever and say
+  so in its README. Its `ruview` bin name is surrendered to `@ruvnet/ruview`
+  either way.
+
+## Consequences
+
+- CJS consumers stop hitting a guaranteed-broken export path (F1 is the only
+  finding that fails for every consumer of that entry point deterministically).
+- The published artifact shrinks ~33% (MEASURED, F2 tarball listing: 62,698 B
+  of maps in a 188 kB unpacked payload) and stops advertising files/transports
+  it does not contain — the package description itself passes the project's
+  claim-check bar.
+- One schema source ends advertised-vs-enforced drift and halves per-call
+  validation cost; naming unification makes the 12-tool surface read as one
+  product and survive strict host tool-name validation.
+- Long-lived MCP servers stop accumulating fds during training campaigns, and
+  job polling survives restarts.
+- Costs: the alias cycle (O4) briefly doubles the advertised tool count unless
+  aliases are router-only (recommended: router-only, advertise underscore names
+  exclusively); folding the CLI (O9) retires a package name already in use in
+  scripts, so it needs a deprecation note.
+- Verification for the implementing PR: `npm pack --dry-run` asserted file list
+  (no `.map`, no phantom entries), pack-size budget in CI (ADR-265), jest/`node
+  --test` suite green, and a tarball-install smoke test for both `import` and
+  the `rvagent` bin.

+| **Codename** | **RUVIEW-NPM-DIST** |
+| **Supersedes / amends** | none (cross-cutting layer above ADR-263 and ADR-264; complements ADR-182 P3/P4) |
+
+## Context
+
+The monorepo now ships (or stages) **three Node packages** with no shared
+distribution engineering:
+
+| Package | Dir | Published | Bin(s) | Tests in CI |
+|---------|-----|-----------|--------|-------------|
+| `@ruvnet/ruview` | `harness/ruview/` | 0.1.0 (live) | `ruview` | **none** |
+| `@ruvnet/rvagent` | `tools/ruview-mcp/` | 0.1.0 (live) | `rvagent`, `ruview-mcp` | **none** |
+| `@ruv/ruview-cli` | `tools/ruview-cli/` | private | `ruview` (collides) | **none** |
+
+Cross-cutting facts established during the ADR-263/264 reviews:
+
+- **Zero CI coverage.** No workflow under `.github/workflows/` references any of
+  the three directories. Two of the packages are *live on the registry* and were
+  published from a laptop state CI never saw. Meanwhile the Rust side has a
+  1,031+-test gate and a witness-bundle culture (ADR-028) — the npm surface is
+  the only shipped artifact class with no verification gate at all.
+- **`ci.yml` pins `NODE_VERSION: '18'`** while all three packages declare
+  `engines.node >= 20`.
+- **Version triplication.** Each package hardcodes its version in source at
+  least once beyond package.json (harness `SERVER_INFO`, rvagent
+  `PACKAGE_VERSION`, cli `.version("0.0.1")`).
+- **Bin-name collision.** Two packages claim the `ruview` bin.
+- **No provenance.** Neither published package carries npm provenance
+  attestations, in a project whose differentiator is signed, reproducible
+  evidence (ADR-028 witness bundles, ADR-182 P4 ed25519/SLSA design).
+- **No pack-content gate.** ADR-264 F1/F2 (broken `require` target, 33% dead map weight — MEASURED, tarball listing — and a phantom
+  `CHANGELOG.md` in `files`) are exactly the defect class an
+  `npm pack --dry-run` assertion catches in seconds.
+
+## Decision
+
+Adopt one distribution layer for all Node packages. Per-package code fixes live
+in ADR-263/264; this ADR fixes the machinery around them.
+
+### D1 — One `npm-packages.yml` CI workflow (the gate)
+
+Matrix over `[harness/ruview, tools/ruview-mcp, tools/ruview-cli]` ×
+Node `[20, 22]`:
+
+1. `npm ci` where a lockfile is committed (the TS packages); the harness
+   installs with `npm install` — repo policy gitignores lockfiles under
+   `harness/`, and the package is dependency-free after ADR-263 O3 so there is
+   nothing to pin.
+2. `npm test` (harness: `node --test test/*.test.mjs` — pin the glob form,
+   the directory form fails on Node 22; TS packages: build + jest or `node:test`
+   per ADR-264 O8).
+3. **Pack gate:** `npm pack --dry-run --json` asserted against a checked-in
+   expected file list + a max unpacked-size budget per package (harness ≤ 60 kB;
+   rvagent ≤ 130 kB post ADR-264 O2). Any new/missing/renamed shipped file is a
+   reviewed diff, not a surprise.
+4. **Tarball smoke test:** install the packed tarball into a temp dir; run
+   `ruview --version`, `ruview doctor`, `rvagent` `--help`-equivalent, and a
+   Node `import()` of each declared export condition — this is the test that
+   would have caught ADR-264 F1 (`require` → nonexistent `dist/index.cjs`).
+5. Bump `ci.yml` `NODE_VERSION` to `'20'` (independent of the matrix above).
+
+### D2 — Publish only from CI, with provenance
+
+Manual `npm publish` from laptops stops. A tag-triggered workflow
+(`ruview-npm-release.yml`, mirroring the firmware release discipline) runs the
+D1 gate, then `npm publish --provenance --access public` under the GitHub OIDC
+token. Consequence: every published version is attested to a public commit +
+workflow run — the npm-side analogue of the ADR-028 witness bundle. The
+`prepublishOnly` script in each package runs the pack gate locally as a
+belt-and-braces (publishing outside CI fails loudly, not silently).
+
+### D3 — Version single-sourcing
+
+Rule: **package.json is the only place a version string lives.** Runtime code
+reads it (`createRequire(import.meta.url)('./package.json').version` or a
+build-time define for the TS packages). CI greps for `\d+\.\d+\.\d+` literals in
+`src/` of each package and fails on match (allowlist: test fixtures). This
+retires ADR-263 F6 and ADR-264 F9 permanently instead of per-incident.
+
+### D4 — Namespace and bin ownership
+
+- `@ruvnet/ruview` **owns the `ruview` bin** (it is the published front door,
+  ADR-182). `@ruv/ruview-cli` renames its bin or folds into `rvagent`
+  (ADR-264 O9) — decided here so neither package ADR relitigates it.
+- New Node packages in this repo use the `@ruvnet/` scope (the `@ruv/` scope
+  holds `rvcsi` legacies; do not grow it).
+- Every package README + description must pass
+  `npx ruview claim-check` — enforced in the D1 gate. The guardrail package
+  linting its sibling packages' claims is the cheapest dogfooding we have
+  (ADR-264 F3 is the standing example of why).
+
+### D5 — Shared-code policy (bounded)
+
+Do **not** introduce an npm workspace or a shared runtime package yet: three
+packages, two of which may merge (ADR-264 O9), do not justify workspace
+machinery, and the harness's zero-dep property is load-bearing. Revisit if a
+fourth package appears or if the `http/cog/config` duplication survives the
+ADR-264 O9 fold. Record the duplication as intentional in each file header (the
+CLI already does this).
+
+## Consequences
+
+- The npm artifacts get the same class of gate the Rust workspace has had since
+  ADR-028: no publish without tests, no shipped file set without an asserted
+  manifest, no version without provenance. The two defects that reached the
+  registry (broken `require` condition, dead maps) become CI-impossible.
+- Cold-path costs stay near zero: the D1 matrix is 6 fast jobs (the harness
+  suite runs in ~108 ms MEASURED; TS builds dominate at a few tens of seconds).
+- Publishing gains one constraint (must go through CI) and loses one failure
+  mode (laptop-state publishes) — the right trade for a project whose brand is
+  reproducible evidence.
+- D3's grep gate is blunt but cheap; if it over-fires, scope it to
+  `version`-adjacent identifiers before weakening it.
+- Follow-ups tracked elsewhere: per-package code fixes (ADR-263 O1–O8, ADR-264
+  O1–O9); ADR-182 P4 (metaharness router + ed25519 provenance chain) remains
+  the deeper provenance story that D2's npm attestations complement, not
+  replace.

+# RuView v0.9.0-realtek-beta.1
+
+This prerelease introduces the Rust-first RTL8720F 2.4 GHz radar transport and
+RuView ingestion path. It is intentionally simulator-validated until Realtek
+hardware and the vendor SDK callback ABI arrive.
+
+## Included
+
+- ADR-263 records the upstream Ameba integration and licensing boundary.
+- ADR-264 defines a versioned, bounded, CRC-protected radar envelope.
+- `rtl8720f-sim` emits deterministic CFR, near-range, far-range, interference,
+  and capability reports to UDP or replay files.
+- The sensing server validates RTL8720F datagrams, publishes bounded summaries
+  over `/ws/sensing`, and exposes the latest report at
+  `/api/v1/radar/latest`.
+- Synthetic provenance is retained end to end as `realtek:simulated`; simulator
+  data is never presented as hardware data.
+
+## Compatibility
+
+The adapter tracks the radar control surface proposed by Ameba RTOS pull
+request #1336 (`wifi_radar_config`, `AT+RAD`, and `AT+RADDBG`). The stable Ameba
+RTOS v1.2.1 release does not yet expose the complete radar receive callback ABI,
+so no vendor-private headers or binary libraries are copied into this release.
+
+## Validation status
+
+- Rust codec round trips, corruption rejection, size bounds, and deterministic
+  simulator tests pass.
+- RuView server ingestion, REST reporting, and source provenance were exercised
+  end to end over loopback UDP.
+- Windows release binaries are built from this branch and accompanied by
+  SHA-256 checksums.
+
+## Known limitations
+
+- No physical RTL8720F board has been flashed or measured.
+- The vendor report callback and exact report layouts remain an SDK/hardware
+  validation gate; the adapter boundary may change when those arrive.
+- This beta exposes transport and aggregate radar observability. Radar-to-pose,
+  vital-sign inference, RF calibration, and accuracy claims are not enabled.
+- 2.4 GHz radar reports are not mislabeled as mmWave or Wi-Fi CSI events.
+
+Do not deploy this prerelease for safety-critical, medical, or occupancy billing
+uses. It is an integration beta for SDK and hardware bring-up.

Give these boards airflow, don't stack or enclose them, and check them by touch during the first several minutes of a new deployment.

 **SENSE-BRIDGE** is a dual-transport [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server that bridges the RuView WiFi-DensePose sensing stack to AI agents (Claude Code, Cursor, ruflo swarms, and any MCP-compatible client).
 
-Install once; AI agents can then call `ruview.presence.now`, `ruview.vitals.get_heart_rate`, `ruview.bfld.last_scan`, and more — without writing HTTP or WebSocket client code.
+Install once; AI agents can then call `ruview_presence_now`, `ruview_vitals_get_heart_rate`, `ruview_bfld_last_scan`, and more — without writing HTTP or WebSocket client code.
 
 ## Quickstart
 
 ```bash
-# 1. Add to Claude Code
-claude mcp add rvagent -- npx @ruvnet/rvagent stdio
+# 1. Add to Claude Code (stdio transport — the default)

 ```
 
 Requirements: **Node.js >= 20**. The `wifi-densepose-sensing-server` Rust binary must be reachable at `RUVIEW_SENSING_SERVER_URL` (default `http://localhost:3000`).
 
-## Feature matrix
+## Tools
+
+Canonical tool names are underscore-form (ADR-264 — host tool-name validators
+commonly enforce `^[a-zA-Z0-9_-]{1,64}$`). The pre-0.1.1 dotted names
+(`ruview.presence.now`, …) are still accepted at call time as deprecated
+aliases; `tools/list` advertises the underscore form only.

-**Transport security (ADR-124 §6)**:
-- **stdio**: process-level isolation — no auth needed for local Claude Code / Cursor.
-- **Streamable HTTP** (`POST /mcp`): Origin header validation (cross-origin → 403), optional bearer token (`RVAGENT_HTTP_TOKEN` → 401 on mismatch), binds `127.0.0.1` by default per MCP spec.
+**Transport security (ADR-124 §6, hardened per ADR-264)**:
+- **stdio** (default): process-level isolation — no auth needed for local Claude Code / Cursor.
+- **Streamable HTTP** (`/mcp`, opt-in via `RVAGENT_HTTP_PORT`): one transport + one MCP server per session (routed by `mcp-session-id`), Origin validation (localhost on any port allowed; anything else → 403), optional bearer token (`RVAGENT_HTTP_TOKEN` → 401 on mismatch), 1 MiB request-body cap (413), binds `127.0.0.1` by default per MCP spec.
 
-**Schema validation**: every tool call runs `zod.safeParse` before dispatch; invalid arguments return `McpError(InvalidParams)` rather than a wrapped string.
-
-**Policy layer** (ADR-124 §4.1a): `ruview.policy.*` tools gate every sensing call — `vitals.*` is default-deny until a policy grant is registered via `npx @ruvnet/rvagent policy grant`. Presence and node-list are allow by default.
+**Schema validation**: each tool declares one Zod schema; the CallTool gate parses exactly once and the advertised JSON Schema is generated from the same Zod source. Invalid arguments return `McpError(InvalidParams)` rather than a wrapped string.

- *   ruview_pose_infer    — single-shot 17-keypoint pose estimation
- *   ruview_count_infer   — single-shot person count with confidence interval

- *   RUVIEW_SENSING_SERVER_URL=http://cognitum-v0:3000 node dist/index.js
+ * Tool naming (ADR-264 O4): canonical names are underscore-form
+ * (host tool-name regexes commonly enforce ^[a-zA-Z0-9_-]{1,64}$). The
+ * pre-ADR-264 dotted names (ruview.bfld.last_scan, …) remain callable as

+ * Validation (ADR-264 O5): each tool declares ONE Zod schema. The CallTool
+ * gate parses exactly once and hands the typed result to the handler; the
+ * advertised JSON Schema is generated from the same Zod source, so what is
+ * advertised is what is enforced.
