feat(server): advertise local RuView installations

ADR-262 §8 question 5 left the second modality open, asking whether it should
be rvcsi. This answers ultrasonic instead, because the cost collapsed:
rufield-adapters now ships UltrasonicReplayAdapter, the first adapter for
Modality::Ultrasonic (registry code 7, empty since v0.1), which parses,
validates and signs BatVu range profiles upstream. RuView only has to decide
what it will put on a wire.

Bumps vendor/rufield 43b1df3 -> 9955672. Two struct literals in bridge.rs gain
fields added upstream (Observation: track_id, attributes, identity_evidence,
channel_sounding_provenance; SensorDescriptor: coordinate_frame, position_m,
orientation_xyzw). All left empty, each for a stated reason rather than a
convenient default — the pose fields in particular, because a CSI link has no
boresight and §6 makes no validated room-coordinate claim. The nine existing
P1 gates pass unchanged.

The decision this module makes is structural rather than a runtime refusal.
The adapter's full per-bin frame is P0 and would be dropped by the egress gate
after all the work of parsing and signing it; its 32-bin coarse reduction is
P1 and egress-safe. So the module does not offer the choice — it configures
the coarse mode, because a consumer cannot un-coarsen a coarse profile whereas
a check can be reordered. The gate still runs and is asserted to drop nothing.

12 gates in tests/ultrasonic_gates.rs, including the honest negative result: an
ultrasonic scan produces no fused inferences at all, and both independent
reasons are pinned. The adapter declines to populate `presence` — one
transducer pair cannot distinguish a person from a coat over the back of a
chair — and the engine's feature vocabulary is entirely statements about a
body, so range_m has nothing to drive.

The fixture is BatVu's own emitter output, byte-identical to the one in
ruvnet/rufield, so schema drift fails a build in one of three repositories
rather than an ingest in a deployment.

Not wired into the running server; P1 shipped as a library before P3 wired it
in, and this follows the same staging.

 - **`archive/v1` (the original pure-Python implementation) formally deprecated (ADR-187)** — commits `1fb5397dd`, `b1417fb6e`; refs #509, #1125. Added `archive/v1/DEPRECATED.md` (a loud tombstone) and a `> ⚠️ DEPRECATED` notice atop `archive/v1/README.md`, both pointing at the maintained `v2/` workspace and the `wifi-densepose 2.x` / `ruview` pip wheel (ADR-117). Records the honest fact behind #509: `archive/v1`'s `DensePoseHead` is **architecture-only** — random `kaiming_normal_` init with **zero committed checkpoints** under `archive/v1/` (MEASURED by Glob over `**/*.{pth,onnx,safetensors,pt,ckpt,bin}`). The ADR-028 deterministic proof `archive/v1/data/proof/verify.py` stays live and is explicitly out of scope. The same effort added a **"Model weights: what's real, what's not" three-tier table** to `README.md` + `docs/user-guide.md`, separating real-and-validated checkpoints (presence 82.3% held-out temporal-triplet, MM-Fi pose 82.69% torso-PCK@20, `count_v1`) from the real-but-weak on-device `pose_v1` (PCK@20 = 3.0%, runtime `confidence=0` stub, below the ADR-079 ≥35% target) from the architecture-only `archive/v1` head — and caveated every live single-ESP32 17-keypoint advertisement accordingly. Docs/labeling only; no code or model behavior changed.
 
 ### Fixed
+- **Pose-vitals, desktop, and repository-integrity issue remediation.** Breathing confidence now measures periodic autocorrelation at the estimated respiratory frequency instead of penalizing clean sinusoidal signals via crest factor (#1610). The desktop launcher resolves the Windows `.exe`, uses `where` for PATH lookup, and passes log filtering through `RUST_LOG`; its React versions, Vite type declarations, and Tauri UI hook working directories are aligned (#1516, #1517, #1518). Runtime session secrets written from `v2/` are ignored, and contributor-harness provenance inputs are pinned to LF across Windows checkouts (#1519, #1520). With explicit owner authorization, the six raw CSI/person-data capture and metadata files identified by ADR-299 were removed from the current tree; historical copies remain pending separately coordinated incident response.
 - **`docs/huggingface/MODEL_CARD.md` had drifted from the model card actually published on the Hub (issue #1481).** Every filename in its "Files in this repo" table (`pretrained-encoder.onnx`, `pretrained-heads.onnx`, `pretrained.rvf`, `room-profiles.json`) pointed at files never uploaded to `ruvnet/wifi-densepose-pretrained` — only `config.json` existed. Replaced the in-repo card with the content actually live on the Hub (`model.safetensors`, `model-q{2,4,8}.bin`, `node-{1,2}.json`, `presence-head.json`, `csi-embed-v2.*`, honest v1→v2 retraction of the single-class "100%" presence claim) and added a "Using with the Rust sensing server (RVF conversion)" section documenting the `--convert-model`/`--convert-out` and `--model` auto-convert paths that neither card previously mentioned.
 - **`--convert-model` failed on the published `model.safetensors`: NUL-padded safetensors header rejected by strict JSON parse (issue #1480, #894 follow-up).** The reference safetensors format pads its JSON header to an 8-byte boundary with trailing NUL bytes; `safetensors_to_rvf` (`wifi-densepose-sensing-server/src/model_format.rs`) fed the full declared-length header slice straight to `serde_json::from_slice`, which rejects the padding as "trailing characters." Since the only published full-precision weight file exercises this padding, `--convert-model` could not convert it at all. Fixed by trimming trailing NUL/whitespace bytes before parsing. Pinned by `safetensors_nul_padded_header_converts` (a header padded to the 8-byte boundary, matching the real HF file, converts and round-trips its weights through `ProgressiveLoader`).
 - **In-server training reconnected — "Start Training" no longer silently no-ops; `/ws/train/progress` streams real progress (ADR-186, issue #1233).** The dashboard's Start Training button POSTed a config, got `success:true`, and nothing happened: `/api/v1/train/start` was a stub that flipped a status string and logged one line, and `/ws/train/progress` 404'd. The full pure-Rust trainer in `training_api.rs` (loads recorded CSI, gradient-descent, exports a `.rvf`) already existed but was **orphaned** — never declared as a module (no `mod training_api;`), so it wasn't compiled at all. Fix (`wifi-densepose-sensing-server`): declared the module, reconciled `AppStateInner` (replaced the `training_status`/`training_config` stub fields with a shared `TrainingState` status handle + cooperative cancel flag + a `training_progress_tx` broadcast), deleted the stub handlers, and merged the real `training_api::routes()` (so `/api/v1/train/{start,stop,status,pretrain,lora}` and `/ws/train/progress` resolve under the existing `/api/v1/*` bearer gate). The training core was decoupled from the ~60-field server state so it is unit-testable. **P5 honesty guarantee:** with `RUVIEW_DISABLE_SERVER_TRAINING` set, start returns a structured `{enabled:false, cli:"wifi-densepose train-room"}` HTTP 409 — never a silent success — and the dashboard disables the Start buttons with a CLI tooltip (enablement is surfaced on `/api/v1/train/status`). Pinned by 8 new tests incl. a **live-socket** test that completes a genuine 101 WebSocket handshake and receives a real progress frame after a POST start, a full POST→poll-status→`.rvf`-exists round-trip, a path-traversal rejection, cancellation, and the disabled-409 path. `cargo test -p wifi-densepose-sensing-server -p wifi-densepose-train --no-default-features` — 0 failed.

 **Scaling:** Each AP distinguishes ~3-5 people (56 subcarriers). Multi-AP multiplies linearly — a 4-AP retail mesh covers ~15-20 occupants. No hard software limit; the practical ceiling is signal physics.

+## Executive decision
+
+RuView will add a clean-room native Rust boundary between RF pose inference and
+semantic publication. It will preserve the immutable RF observation, publish a
+physics assessment, optionally produce a bounded corrected candidate, and
+abstain when required evidence is absent. It must never increase observational
+confidence merely because a pose is physically plausible.
+
+Three independently gated layers are adopted:
+
+1. A deterministic kinematic auditor and bounded covariance-weighted projector
+   using Rust and `nalgebra`.
+2. An optional articulated-body dynamics auditor using `rapier3d`.
+3. A later optional supervised residual model using Burn.
+
+The first production milestone is deterministic audit. It is not a GRIP port,
+not PPO, and not evidence that the current pose observer is production-ready.
+
+## Context
+
+ADR-101's committed Cog emits 17 COCO keypoints as normalized 2D coordinates.
+Its model has no per-joint uncertainty head and publishes a constant confidence.
+The sensing server also contains renderer-oriented EMA and bone clamping. These
+surfaces cannot establish metric 3D physics and can make weak evidence look
+more convincing.
+
+Pose output can violate bone length, floor, velocity, acceleration, and temporal
+continuity constraints. Downstream consumers also cannot reliably distinguish
+observed coordinates from derived correction. The rejected premise is:
+"physically plausible means more likely correct." Plausibility is only a prior;
+many incorrect poses are plausible.
+
+GRIP is architectural inspiration for an observer/controller split, but it
+observes four wearable IMUs and pressure insoles and drives a simulator. RuView
+observes RF, so GRIP weights are not input-compatible. External code, weights,
+simulators, and datasets require independent license review and never enter the
+runtime dependency graph by implication.
+
+## Outcome and actors
+
+For every accepted person track/timestamp, the engine returns exactly one
+`PoseRefinementV1`, including off, timeout, rejection, and abstention paths:
+
+- immutable `PoseObservationV2` content hash;
+- constraint residuals and quality disposition;
+- an optional bounded candidate and an explicit `selected` bit;
+- a typed reason when correction is unavailable;
+- model, calibration, configuration, and optional learned-artifact provenance.
+
+The RF observer owns observations and calibrated uncertainty; tracking owns
+identity stability; physics owns assessment/correction only; the sensing server
+owns deadlines, modes, publication, and rollback; the evidence engine owns
+release evaluation; clients choose raw/both/refined without silent fallback.
+
+## Input and coordinate contract
+
+Metric correction requires a monotonic nanosecond timestamp, session-scoped
+track ID, sequence and sensor epoch, 17 ordered COCO joints in metric X/Y/Z,
+per-joint positive-semidefinite covariance calibrated on held-out data, a
+versioned right-handed Z-up room frame, a normalized upward floor plane, model
+and calibration hashes, ADR-302 trust state, and authenticated/replay-protected
+source provenance.
+
+`Image2d` observations may be audited for image-plane ratios and continuity but
+must never enter 3D projection/dynamics or be called physically corrected.
+Unknown trust, missing calibration, missing uncertainty, stale/non-monotonic
+input, non-finite values, invalid covariance, excessive tracks, and room-bound
+violations fail to raw output with a typed reason.
+
+## Public contracts
+
+`wifi-densepose-core` owns `PoseObservationV2` and `PoseRefinementV1`; no
+duplicate server/Cog contract is permitted. Public output remains COCO17. The
+engine derives pelvis and thorax virtually and never labels them observed.
+
+The raw content hash is deterministic and excludes its own hash field. The
+idempotency key is `(sensor_epoch, sequence, track_id, raw_hash, config_hash)`.
+An exact duplicate returns the cached result; same sequence with different
+content is a replay rejection.
+
+Contact is `hypothesis` unless a measured sensor and its provenance say
+otherwise. Raw, derived, hypothesis, and unknown labels must survive every
+projection.
+
+## Confidence invariant
+
+For upstream calibrated confidence `c_obs`, normalized residual `r`, and
+normalized intervention `i`:
+
+```text
+c_physics = exp(-(beta_r * r + beta_i * i))
+c_effective = min(c_obs, c_obs * c_physics)
+0 <= c_effective <= c_obs <= 1
+```
+
+Only a separately witnessed multimodal fusion contract may increase fused
+confidence.
+
+## Deterministic projector
+
+The default `kinematic` feature has no Rapier, Burn, ONNX, libtorch, Python,
+CUDA, or network dependency. Per bounded iteration it:
+
+1. projects observed parent/child distances toward anonymous track-scoped
+   bone-length posteriors;
+2. applies broad joint/trunk validity checks without an upright prior;
+3. bounds temporal motion and resets derivatives after gaps;
+4. resolves floor penetration only, allowing seated, kneeling, prone, child-
+   scale, mobility-aid, and genuine-fall poses;
+5. recomputes residuals and stops below epsilon.
+
+Initial operator-owned caps are four iterations (hard maximum eight), 0.20 m
+single-joint correction, 0.10 m root correction, 250 ms derivative gap, 500 ms
+track reset, ten known joints, a 100 m metric room bound, a separate 16,384
+image-coordinate audit bound, and a 5 ms one-track Pi 5 p95 gate. Keeping image
+and metric bounds separate prevents legitimate pixel observations from
+weakening the physical room bound. A candidate over either correction cap is
+discarded in full.
+
+Bone posteriors are initialized only from high-confidence frames, anonymous,
+memory-only, track-scoped, and deleted on expiry. Persistent personalization is
+outside this ADR and requires consent/retention/deletion governance.
+
+## Optional dynamics and learned layers
+
+`dynamics` adds a process-owned Rapier humanoid and begins audit-only. Network
+input may never provide Rapier snapshots, bodies, constraints, solver limits,
+or arbitrary geometry. Dynamics approval is independent of kinematic approval.
+
+`learned` uses first-party Burn 0.21 core/NN components without `burn-tch`
+because this workspace already has a different native libtorch link.
+`learned-cpu` adds the ndarray backend. The implemented two-layer GRU uses a
+20-frame history and width 128 to predict bounded residuals, uncertainty,
+foot-contact hypotheses, and abstention. Verified model records can be loaded
+from bytes and executed natively; no trained artifact is shipped or approved.
+The resolved Burn/CubeCL graph declares Rust 1.92, while the workspace file
+pins Rust 1.89 and the authoring host provides Rust 1.91.1.
+`--ignore-rust-version` is diagnostic evidence only: learned activation remains
+blocked until an approved Rust 1.92 release-toolchain change builds it without
+that override. Residuals are hard-clipped to deterministic caps and cannot
+bypass validation or confidence monotonicity. PPO is deferred until measured
+evidence identifies a failure supervised residual learning cannot address.
+
+## Feature boundary
+
+```text
+default = kinematic
+dynamics = rapier3d
+learned = burn-core + burn-nn
+learned-cpu = learned + burn-ndarray
+learned-train = learned + burn-train
+learned-wgpu = learned-train + burn-wgpu
+learned-cuda = learned-train + burn-cuda
+deterministic = rapier3d?/enhanced-determinism
+```
+
+The lockfile is release authority. The learned feature currently requires the
+toolchain supported by Burn/CubeCL's resolved graph; this does not change the
+default edge build.
+
+## Runtime modes and API
+
+Rollout is `OFF -> AUDIT -> SHADOW_CORRECT -> OPT_IN_CORRECT -> DEFAULT_CORRECT`.
+Evidence permits forward transitions; any regression returns immediately to
+audit/off. Correct selection additionally requires authenticated sensor
+identity and replay protection from ADR-305. High model confidence cannot
+override missing source authentication.
+
+Existing pose fields stay unchanged and raw remains the migration default:
+
+```text
+GET /api/v1/pose/current?view=raw
+GET /api/v1/pose/current?view=both
+GET /api/v1/pose/current?view=refined
+```
+
+Refined-only returns HTTP 409 with `pose_refined_unavailable` when no selected
+candidate exists. It never silently returns raw labeled refined.
+
+## Security, privacy, and availability
+
+All frames, model output, geometry, and pre-verification artifacts are
+untrusted. Calibration/config/model artifacts become trusted only after signed,
+hash-addressed verification and atomic activation. Runtime inference performs
+no model retrieval or other network access.
+
+Fixed arrays/caps, bounded iterations, a maximum track count, room geometry
+limits, deadlines, and track expiry constrain denial of service. Timeout drops
+partial refinement, never raw publication. Backpressure retains the newest raw
+frame per track, drops intermediate refinement work, resets derivatives after
+250 ms, and never extrapolates beyond 500 ms.
+
+Metrics contain only allowlisted aggregate scalars: mode/disposition/reason,
+stage latency, iterations, maximum correction, residuals, confidence delta,
+track resets, invalid input, timeout, and raw/refined divergence. They exclude
+joint arrays, body dimensions, room coordinates, CSI, and persistent person
+identifiers. Bone/gait state is memory-only and excluded from logs.
+
+Refined output is not a sole medical, emergency, industrial-safety, or
+autonomous-control source. A real fall is valid state and must never be made
+upright to stabilize a simulator.

+
+## Evidence protocol
+
+Evidence levels are L0 deterministic synthetic, L1 public measured replay, L2
+controlled RuView RF plus optical truth, L3 subject/room/hardware/session-
+disjoint RuView, L4 privacy-safe shadow fleet aggregates, and L5 independent
+vertical validation outside this ADR.
+
+No sequence, contiguous take, subject, room, or calibration session may cross
+train/test for the generalization gate. Preprocessing, body priors, and
+uncertainty calibration fit training data only. Reports include raw observer,
+renderer smoothing, audit, deterministic correction, dynamics audit, and
+learned residual on identical observations, plus empty-room, prone/fall,
+missing-joint, and OOD subsets.
+
+Primary metrics are 3D MPJPE, declared-threshold PCK, per-joint error, foot
+slide, floor penetration, jerk, uncertainty calibration, abstention coverage,
+and selective risk. Learned runs use at least five fixed seeds and report mean,
+median, standard deviation, and 95% bootstrap intervals. All frames count;
+selective metrics report risk and coverage.
+
+## Acceptance gates
+
+- **G0 contract**: real metric 3D/covariance output, round-trip raw hash,
+  versioned frame/floor, 2D compatibility, non-stub observer, ADR-298 artifact
+  sanity, and the ADR-079 PCK@20 >=35% gate or adopted successor. The current
+  committed Cog does not pass G0, so correction remains unavailable.
+- **G1 deterministic audit**: property/fuzz tests, deterministic hashes per
+  platform class, 24-hour accelerated replay without panic/growth, Pi 5 p95
+  <=5 ms, and universal confidence monotonicity.

+  better; no joint median >5 mm worse; fall/prone sensitivity change <=2 pp;
+  >=95% corrections below 0.10 m; every correction above 0.20 m abstains.
+- **G3 opt-in**: >=30 subjects, 10 rooms, 3 hardware configurations, and 3
+  independent sessions/room; UNKNOWN never selected; confidence monotonic;
+  live disable; REST/WebSocket/MQTT/Home Assistant/replay compatibility.
+- **G4 default visualization only**: 30 shadow days under 0.1% timeout/internal
+  error, no open severity 1/2 incidents, and gates still valid for current
+  model/calibration.
+
+Dynamics and learned engines each repeat G2-G4; approval is not inherited.
+

+SBOM/license report, rollback drill, and residual-risk owners. Missing measured
+or operational evidence leaves status Proposed and runtime in audit.
+
+## Rollback
+
+Rollback is an authenticated mode transition to audit/off, not a binary
+downgrade. Stop selection immediately, keep raw publication and disposition
+records, discard track state, and retain only aggregate incident metrics plus
+signed configuration history. Failed artifact activation leaves the previous
+engine atomically active. Additive schemas remain; refined-only callers receive
+the typed unavailable response.
+
+## Consequences
+
+### Positive
+
+- Explicit anti-hallucination and provenance boundary after RF inference.
+- Reusable native Rust consistency primitive with measurable abstention.
+- Python/CUDA remain absent from the production default.
+- Cross-modal teacher data remains possible without wearable runtime inputs.
+
+### Negative
+
+- Full value requires a real metric 3D observer and calibrated uncertainty.
+- Stateful tracks add latency/memory; optional backends add supply-chain surface.
+- A constrained but wrong pose can look more credible.
+- Strict data collection costs more than the software implementation.
+
+### Neutral
+
+- This ADR does not improve RF observability or current weight evidence.
+- Existing 2D consumers continue to function.
+
+## Implementation phases
+
+P0 contracts/schemas; P1 deterministic audit; P2 bounded shadow correction; P3
+server/Cog publication and evidence ledger; P4 Rapier audit; P5 Burn residual
+training/inference. Code may land ahead of evidence, but runtime authority
+advances only through the gates above.
+
+## Implementation status at proposal
+
+- P0-P3 are implemented on this branch: canonical contracts, strict schemas,
+  deterministic audit/projection, authenticated correction receipts,
+  idempotency, bounded track state, latest-frame backpressure, additive HTTP
+  and WebSocket publication, live legacy-2D audit, privacy-safe metrics, golden
+  replay, and strict-split checks.
+- P4 is implemented as an optional persistent per-track Rapier dynamics auditor
+  and remains audit-only pending independent G2-G4 evidence.
+- P5 inference architecture, artifact verification, serialization, and native
+  CPU execution are implemented. Training data, a signed trained artifact, and
+  G2-G4 accuracy/calibration evidence do not exist, so the layer has no runtime
+  selection authority. Its resolved Rust 1.92 requirement is also an explicit
+  activation blocker on the current Rust 1.91.1 release host.
+- The live Cog honestly emits `Image2d`, degraded trust, and uncalibrated
+  uncertainty. It can be audited but cannot be selected for 3D correction.
+  G0 therefore remains open until an independently released metric-3D observer
+  with calibrated covariance is integrated.
+- Local x86 latency and synthetic contract checks are recorded in the append-
+  only evidence ledger. Pi 5 measurements, 24-hour replay, 100-million-case
+  fuzzing, held-out RF/optical accuracy, fleet shadowing, and vertical safety
+  validation remain release evidence gates rather than software claims.

+
+## 1. Context
+
+### 1.1 The question this ADR answers
+
+"Can we use [`icurtis1/off-axis-sneaker`](https://github.com/icurtis1/off-axis-sneaker)
+with RuView?" The answer is: **yes for the technique, no for the code, and
+only honestly for the RF part.** This ADR records the research behind each of
+those three clauses and defines the integration that is actually defensible.
+
+### 1.2 What off-axis-sneaker is
+
+`off-axis-sneaker` is a React + TypeScript + Vite web app that renders a GLB
+model (a sneaker) in three.js and creates a *head-coupled perspective*
+("fish-tank VR" / "window into the screen") illusion:
+
+- **Tracking input**: MediaPipe Face Mesh (468 facial landmarks) from a
+  webcam. Head (x, y) comes from the eye midpoint; depth (z) is proxied by
+  inter-ocular distance. An exponential moving average (default factor 0.3)
+  smooths jitter; sensitivity multipliers are `strengthX: 4`, `strengthY: 3`,
+  `strengthZ: 2`.
+- **Projection**: `src/utils/offAxisCamera.ts` builds a **true asymmetric
+  (off-axis) frustum** — `makePerspective(left, right, top, bottom, near, far)`
+  with `left/right/top/bottom = (screenBound − eyePosition) · (near /
+  viewerToScreenDistance)` — i.e. Kooima's generalized perspective projection,
+  plus a matching camera translation. Constants: `nearPlane 0.05`,
+  `farPlane 1000`, `worldScale 0.01` (cm → world units), `movementScale 1.5`.
+- **Calibration**: a wizard captures physical screen width/height (cm),
+  typical viewing distance, and pixel density, stored locally, so eye position
+  is computed relative to the *physical* display.
+
+The technique descends from Johnny Chung Lee's 2007 Wii-remote desktop VR
+demo and the fish-tank VR literature (Ware, Arthur & Booth, CHI '93). The
+projection math is Robert Kooima's "Generalized Perspective Projection"
+(2008). Both are public, well-documented techniques independent of any one
+implementation.
+
+### 1.3 What the illusion physically requires
+
+The head-coupled illusion is only convincing when the tracked eye position is
+**accurate to roughly centimeters** and **low-latency**. The VR literature
+puts comfortable motion-to-photon latency below ~20 ms for head-mounted
+displays; desktop fish-tank VR tolerates more, but visible lag between head
+motion and parallax response is exactly what breaks the "window" illusion.
+`CLAIMED` (literature values; no RuView measurement exists for this demo yet).
+
+### 1.4 What RuView RF sensing can actually supply today
+
+This is where honesty is mandatory (repo rule: never present WiFi sensing as
+camera-grade).
+
+- **Field-peak position, not metric localization.**
+  `wifi-densepose-sensing-server/src/field_localize.rs` derives a position
+  from the strongest peak of the 20×20 `signal_field` carried on
+  `/ws/sensing` `sensing_update` frames. Its own module doc states the
+  caveat: the subcarrier→angle mapping is a *representation*; "a single ESP32
+  link cannot resolve a true (x, z) room position." The emitted position is
+  "strongest field peak in the room model," mapped with `X_SCALE 0.6`,
+  `Z_SCALE 0.5`, gated by `PEAK_THRESHOLD 0.35` — real, live, motion-tracking,
+  but **not a calibrated person fix** and nowhere near eye-position precision.
+- **RF pose is 2-D, normalized, constant-confidence.** The committed Cog
+  (ADR-101, restated by ADR-323) emits 17 COCO keypoints as normalized 2-D
+  coordinates with a constant confidence and no per-joint uncertainty. A
+  "nose" keypoint exists (COCO index 0), but it is not a metric 3-D head fix.
+- **Tracks are coarse and pseudonymous by design.** `ruview-track` (ADR-307)
+  maintains `person_N` tracks with container-level ("kitchen → hallway")
+  continuity, coarse non-reversible features, and asserts **no accuracy
+  number** — outputs default to evidence level `L1`.
+- **Update cadence and latency are unmeasured for this purpose.** The demo
+  pipeline runs at ~30 Hz on the MediaPipe side (ADR-170), but no end-to-end
+  RF motion-to-photon latency has been measured. Any figure quoted for the RF
+  path must be tagged `MEASURED` with a reproducer before it appears in docs
+  or UI.
+
+Conclusion of the capability match: **RF cannot drive a convincing fish-tank
+illusion by itself today**, and this ADR does not claim it can. RF *can*
+supply things a webcam cannot: camera-free presence, zone-level position,
+person count, approach direction, and pseudonymous continuity — including
+when the camera is off.
+
+### 1.5 What this ADR is *not*
+
+- Not a vendoring of `off-axis-sneaker` (see §2.1 — the repo has no license).
+- Not a claim of camera-grade RF head tracking, at any tier.
+- Not a backend change: no new server endpoints, no new auth surface, no
+  schema changes. Purely additive client-side HTML/JS, like ADR-169/170.
+- Not a React/Vite/Tailwind adoption. The `examples/three.js/demos/*` are
+  dependency-light single-file HTML demos and stay that way.
+
+## 2. Decision
+
+### 2.1 Licensing: adopt the technique, not the code
+
+`off-axis-sneaker` publishes **no license**. Under default copyright, its
+source cannot be copied, vendored, or translated into this repository.
+Decision:
+
+1. **No code, assets, or models from `off-axis-sneaker` enter this repo.**
+   The GLB sneaker model is likewise unlicensed for reuse; demos use assets
+   already present in `examples/`.
+2. The off-axis projection is implemented **clean-room from the public
+   sources**: Kooima's "Generalized Perspective Projection" (2008) — the
+   `pa/pb/pc` screen-corner formulation — and three.js's documented
+   `PerspectiveCamera.projectionMatrix` override path. The repository is cited
+   as prior art in this ADR only.
+3. If upstream later adds a permissive license, revisiting reuse requires a
+   new ADR note, not silent copying.
+
+### 2.2 Tiered integration — each tier labeled by what it really is
+
+**Tier A (ships first): webcam-fine + RF-context hybrid.**
+`07-off-axis-window.html` uses MediaPipe Face Landmarker (already the pattern
+in demo 05) for fine head tracking and the Kooima frustum for rendering —
+functionally what off-axis-sneaker does, reimplemented. RuView RF adds the
+camera-free layer around it:
+
+- **Presence-gated camera**: the webcam pipeline starts only when the RF
+  presence signal (`/ws/sensing` `sensing_update`) says someone is in the
+  zone, and stops after a configurable RF-vacancy timeout. The privacy
+  posture improves: the camera is *off* until physics says there is someone
+  to track.
+- **Multi-person arbitration**: when RF reports more than one person, the HUD
+  says so and the demo holds the last stable perspective instead of jumping
+  between faces.
+- **Pre-warm**: RF approach direction (field-peak trajectory) warms up
+  MediaPipe and the scene before the person sits down.
+
+**Tier B (demo mode, prominently labeled): RF-only coarse parallax.**
+A toggle drives the off-axis eye position from RF alone — field peak (x, z)
+plus the pose nose keypoint when present — through a one-euro filter, a
+deadband, and a hard gain clamp. The HUD labels it **"RF coarse body
+parallax — not head tracking"** and shows the live evidence level (`L1`
+heuristic unless a certificate says otherwise, per ADR-282/ADR-318). The
+expected experience is a slow, body-scale parallax sway — a demonstrative
+"the room model moves because *you* moved, with no camera" — not a stable
+fish-tank illusion. The demo must never present Tier B as equivalent to
+Tier A.
+
+**Tier C (future, explicitly gated, not promised): metric RF head position.**
+Only a calibrated multistatic deployment (ADR-297 multi-node semantics,
+ADR-311 fusion, ADR-303 ground-truth sync) with an evidence-engine ledger
+entry (ADR-304) and a capability certificate (ADR-318) could justify feeding
+RF positions into the fine path. No current data supports this; Tier C exists
+in this ADR solely so nobody ships it informally without those gates.
+
+### 2.3 Implementation surface
+
+- New file `examples/three.js/demos/07-off-axis-window.html` (07, not 06 —
+  ADR-170 reserves `06-yoga-mode.html`). Single-file demo following the 01–05
+  conventions: same CSS custom properties, same HUD/helper-panel pattern,
+  served from the existing static demo server
+  (`http://127.0.0.1:8765/examples/three.js/demos/…`).
+- A small clean-room module (inline `<script type="module">` or
+  `examples/three.js/lib/off-axis-camera.js` if shared later) that, given
+  screen corners `pa, pb, pc` (from calibration) and eye point `pe`, sets
+  `camera.projectionMatrix` via the Kooima formulation each frame.
+- Data inputs are the **existing** streams only: `/ws/sensing`
+  (`sensing_update` → `signal_field` → field peak, using the same
+  `X_SCALE`/`Z_SCALE`/`PEAK_THRESHOLD` mapping as `field_localize.rs`) and,
+  when available, `/api/v1/stream/pose` for the nose keypoint. WebSocket
+  access uses the existing ticket flow (`ws_ticket.rs` / `bearer_auth.rs`);
+  no endpoint is exempted or added.
+- Calibration mirrors the sneaker app's concept without its code: screen
+  width/height in cm, viewing distance, persisted in `localStorage` under a
+  demo-scoped key. No calibration data leaves the browser.
+- Provenance discipline: if the demo is pointed at a synthetic or replayed
+  source, the ADR-295 provenance state must surface in the HUD exactly as the
+  Observatory does — synthetic can never present as live.
+
+### 2.4 Honesty and evidence rules binding this feature
+
+1. Every user-visible latency, accuracy, or precision statement in the demo,
+   README, or docs carries a `MEASURED` (with reproducer), `CLAIMED`, or
+   `SYNTHETIC` tag. This ADR itself contains no `MEASURED` claims.
+2. Tier B is labeled coarse body parallax in the HUD at all times; there is
+   no configuration that hides the label while RF drives the camera.
+3. No PCK or pose-accuracy number may be quoted for the RF path without the
+   mean-pose baseline and a leakage-free held-out split (repo rule).
+4. The webcam feed never leaves the browser; no frames, landmarks, or
+   embeddings are sent to the server. RF data continues to obey ADR-307's
+   privacy invariants (pseudonymous, coarse, rotatable).
+
+### 2.5 Implementation status (2026-08-16 amendment)
+
+The projection core shipped as a **Rust crate compiled to WASM** rather than
+the inline JS module §2.3 anticipated — a strict upgrade with the same
+surface: `v2/crates/ruview-offaxis` (dependency-free native core; wasm-bindgen
+only on wasm32) implements the Kooima projection, the one-euro filter, the
+field-peak mapping (constants mirroring `field_localize.rs`), and the Tier B
+coarse-parallax stage with its deadband/gain/clamp bounds enforced in Rust.
+`examples/three.js/demos/07-off-axis-window.html` consumes the wasm-bindgen
+output (built locally per the crate README; generated artifacts are not
+committed). Validation and `MEASURED` benchmarks live in the crate README.
+The demo ships with a `SYNTHETIC`-labeled mouse simulator and the labeled
+Tier B RF mode; a Tier A fine tracker connects through
+`OffAxisCamera.update_normalized` and remains host-provided.
+
+## 3. Options considered
+
+| Option | Verdict | Why |
+|---|---|---|
+| Vendor `off-axis-sneaker` (or fork + point at RuView) | **Rejected** | No license ⇒ no redistribution rights. Also React/Vite stack conflicts with the repo's single-file demo convention. |
+| Clean-room Kooima off-axis demo, webcam-fine + RF-context (Tier A/B) | **Chosen** | Legally clean, matches demo conventions, uses RF for what it is actually good at, and demonstrates camera-free presence value honestly. |
+| RF-only head-coupled perspective as the headline | **Rejected** | Over-claim. Single-link field peaks are a representation, not metric localization (`field_localize.rs` caveat); shipping this as "head tracking" violates the camera-grade rule. Survives only as the labeled Tier B toggle. |
+| Wait for multistatic metric localization (Tier C) before any demo | **Rejected** | Blocks a useful, honest demo on a phase-2/3 program (ADR-303/311/318) with no delivery date. The gates are recorded instead. |
+| Add a dedicated server endpoint for head position | **Rejected** | Unnecessary — existing `/ws/sensing` + `/api/v1/stream/pose` suffice; a new endpoint would expand the auth surface for no capability gain. |
+
+## 4. Consequences
+
+**Improves**
+
+- A publicly legible demo of RF sensing's actual differentiator: the scene
+  knows you are there, where you roughly are, and how many of you there are —
+  before and without any camera.
+- Privacy posture of the head-tracking demo class: camera duty-cycle is
+  bounded by RF presence instead of always-on.
+- Canonical, licensed off-axis projection code the Observatory or future UI
+  can reuse.
+
+**Costs / risks**
+
+- Tier B can underwhelm viewers primed by webcam demos; the mitigation is the
+  labeling and the side-by-side toggle, not inflated gain.
+- MediaPipe CDN dependency (same as demo 05) remains a network-availability
+  risk for Tier A; the demo must degrade to Tier B with a visible notice.
+- Screen-calibration friction (cm measurements) may deter casual users; a
+  "skip calibration (approximate)" path with degraded-accuracy labeling is
+  acceptable.
+- Upstream `off-axis-sneaker` may change or add a license; tracking that is
+  manual.
+
+**Follow-ups (not in this ADR's scope)**
+
+- Measure end-to-end RF motion-to-parallax latency with a reproducer and
+  publish it `MEASURED`.
+- If/when ADR-303/311 land, evaluate Tier C against the ADR-318 certificate
+  gate.
+- Consider promoting the off-axis camera module into the Observatory 3D view.
+
+## 5. Validation
+
+- Demo checklist (manual, per ADR-169/170 practice): loads from the static
+  server; Tier A activates only on RF presence; Tier B label visible whenever
+  RF drives the camera; provenance badge correct against a synthetic source;
+  no network requests carrying webcam-derived data (verified in devtools).
+- `rg` gate before merge: no file under `examples/` contains code originating
+  from `icurtis1/off-axis-sneaker`.
+- No workspace, harness, or firmware validation rows are triggered — the
+  change is a static HTML demo plus this document.

+# ADR-325: Cognitum Spaces activation and governed spatial exchange
+
+- **Status**: Accepted — legacy and versioned reads, OAuth activation, local spatial memory, governed-action policy, metaharness support, and npm distribution are implemented; HTTPS production evidence is complete
+- **Date**: 2026-08-17
+- **Deciders**: ruv
+- **Tags**: cognitum-spaces, oauth, spatial-state, privacy, ruvector, policy, autogenous
+- **Relates to**: ADR-271, ADR-277, ADR-304, ADR-306, ADR-312, ADR-318, ADR-319, ADR-321; Cognitum API ADR-094; Autogenous ADR-402
+
+## Context
+
+RuView produces camera-free RF perception locally. Cognitum Spaces provides a
+tenant-scoped cloud projection of physical places. Autogenous ADR-402 proposes
+using that projection as a spatial-intelligence input for agent coordination.
+The useful product is not another sensor dashboard: it is a governed chain from
+local perception to spatial state, persistent memory, explanation, and action.
+
+Four product pillars define the requested integration:
+
+1. **Spatial state** — sites, buildings, floors, rooms/spaces, zones, entities,
+   semantic events, and alerts.
+2. **RuView perception** — camera-free sensing is normalized locally before any
+   permitted P2/P3 semantic event synchronizes.
+3. **Persistent memory** — RuVector grounds anomaly explanations in
+   tenant-scoped spatial history.
+4. **Governed action** — agents observe or recommend by default; consequential
+   execution requires explicit policy authorization.
+
+The live API audit on 2026-08-17 established the current production boundary:
+
+- `GET https://api.cognitum.one/v1/spaces` exists and returns a bounded list;
+- an unauthenticated request is rejected;
+- the current account has no paired sites, so the authenticated result is an
+  empty list rather than fabricated sample state;
+- the projection declares HomeCore Edge authoritative and excludes raw CSI,
+  CIR, RF tensors, recordings, pose frames, vital waveforms, and identity
+  observations;
+- the first deployed Function revision accepted only legacy `cog_` API keys;
+- the gateway was configured to authenticate private Function hops, but the
+  direct Function endpoint was still publicly invokable; that bypass has now
+  been closed and the exact gateway runtime service account is the only
+  invoker;
+- OAuth protected-resource metadata and a RuView-scoped OAuth accept path were
+  absent.
+
+The Autogenous review at commit
+`f7fa308b261bac89a8909edae8a3fdbbfb8ce66c` found additional integration risks:
+
+- its Spaces client only listed spaces; no governed ingest contract existed;
+- it trusted a loose TypeScript cast, with no response-size, timeout, redirect,
+  or strict semantic-boundary validation;
+- its observation conversion dropped tenant/message/sequence identity;
+- missing confidence became zero but could still enter fusion;
+- provenance could be substituted for calibration identity;
+- a Spaces-derived belief could be converted back into an observation and
+  counted as independent corroboration, laundering one source into two;
+- its API-key exchange returns a `cognitum-cli` OAuth token, but the live Spaces
+  endpoint accepted only a `cog_` key. Calling this “OAuth Spaces access” was a
+  contract mismatch.
+
+## Decision
+
+Adopt a one-way-by-default, typed spatial exchange with separate activation,
+data, memory, and action authorities.
+
+```text
+RuView RF capture (P0/P1, local)
+  -> calibrated/OOD-gated semantic observation
+  -> ontology + evidence + witness envelope (P2/P3)
+  -> HomeCore authoritative edge state
+  -> Cognitum Spaces tenant/workspace projection
+  -> RuView bounded read client / Autogenous spatial context
+  -> RuVector tenant-scoped memory and explanation
+  -> recommendation
+  -> ruvview-policy authorization + approval + receipt
+  -> optional consequential action
+```
+
+Cloud state is a projection of edge state, not a second sensor and not an
+independent corroborating modality.
+
+### 1. Activation and data-plane credentials are distinct
+
+RuView uses Cognitum's existing Authorization Code + PKCE flow with the public
+`ruview` client. A user explicitly requests `spaces:read` with
+`wifi-densepose login --spaces`. The authorization-server registration is a
+ceiling; ordinary sensing login does not silently gain cloud access.
+
+The Spaces resource server accepts either:
+
+- a legacy API key carrying `spaces:read` (or the migration-compatible
+  predecessor `devices:manage`); or
+- a Cognitum OAuth access token that passes every condition below.
+
+OAuth acceptance is conjunctive:
+
+| Check | Required value |
+|---|---|
+| Signature | ES256 against `https://auth.cognitum.one/.well-known/jwks.json` |
+| Issuer | exact `https://auth.cognitum.one` |
+| Audience | exact `ruview` |
+| Client claim | exact `ruview` |
+| Token type | ordinary `access`; setup/workload tokens denied |
+| Lifetime | current `exp`/`nbf`, five-second clock tolerance only |
+| Scope | exact token `spaces:read` member |
+| Tenant binding | valid non-empty UUID `org_id` and `workspace_id` |
+
+An API key is not called OAuth. An OAuth token is not stored in
+`COGNITUM_SPACES_API`. The compatibility environment variable contains an API
+key only and is never printed, logged, or committed.
+
+OAuth consent grants identity-bound read access. It does **not** grant device
+pairing, data publication, deployment, billing, spending, leases, learning
+promotion, automation installation, commands, or actuator authority.
+
+The contributor metaharness exposes this as CLI verb `spaces` and MCP tool
+`ruview_spaces_list`. It delegates to the same Rust client rather than parsing
+or refreshing OAuth independently. The tool never accepts a bearer token or API
+key. MCP use requires an operator-provided `credential-use` grant, and MCP calls
+cannot select the credential path or API origin. The adapter requires an
+installed `wifi-densepose` binary rather than executing Cargo build scripts
+from an auto-detected checkout while holding credential authority. Because
+refresh tokens rotate, a read may atomically update the local OAuth credential
+before contacting Spaces; this authentication side effect is disclosed and
+does not add cloud write authority.
+
+### 2. The gateway owns the private credential relay
+
+The public gateway strips inbound `X-Cognitum-User-Authorization` and
+`X-Serverless-Authorization`. For a locked Function upstream it then:
+
+1. retains a legacy `cog_` credential in `X-API-Key`, or, for the exact Spaces
+   route only, retains a non-key bearer in a gateway-owned internal header;
+2. replaces `Authorization` with the gateway's Google invoker ID token;
+3. fails closed with `503` if it cannot mint that hop identity;
+4. forwards only to the configured Function origin.
+
+The Function's Cloud Run invoker check is enabled. `allUsers` has no invoker
+binding; only the exact `apigateway-sa` service account may invoke it. This is
+required because otherwise a caller could bypass Cloud Armor and spoof an
+internal relay header.
+
+The API publishes RFC 9728 protected-resource metadata naming the authorization
+server and `spaces:read` scope. Discovery describes capability; it does not
+grant it.
+
+### 3. Tenant isolation is part of authentication
+
+Legacy API-key documents are queried by their existing owner-bound `tenantId`.
+OAuth requests are conjunctively queried by both signed `org_id` and
+`workspace_id` using stored `tenantId` and `workspaceId` fields. The public
+tenant identifier is projected from signed `org_id`. A request cannot supply
+either selector in a query string.
+
+No cross-tenant aggregation exists on this path. Pagination, search, memory,
+and event endpoints added later must carry the same authoritative principal;
+client-provided tenant filters may only narrow within it, never replace it.
+
+### 4. Spatial model and ownership
+
+The canonical RuView vocabulary remains ADR-306:
+
+```text
+Site -> Building -> Floor -> Space -> Zone
+                                  -> Sensor / Person / Object / Track
+                                  -> Observation -> Event -> Alert
+```
+
+Cognitum may call a bounded room a “space”; RuView does not create a second
+room type. Stable external IDs are namespaced and validated before entering the
+ontology. HomeCore remains authoritative for local registry state and local
+automation. Cognitum owns tenant/workspace projection and activation. RuVector
+owns indexed spatial history, not tenancy or authorization.
+
+The current live endpoint exposes the first `Space` slice only. Sites, floors,
+zones, entities, events, and alerts are contract milestones, not inferred from
+missing fields. A client must represent absence as unknown/unavailable and must
+not fabricate parents, coordinates, people, alerts, or provenance.
+
+### 5. Privacy boundary and synchronization eligibility
+
+Only allow-listed P2/P3 semantic projections may cross the cloud boundary.
+
+| Class | Examples | Cloud default |
+|---|---|---|
+| P0 | raw CSI, CIR, RF tensors, packet captures | prohibited |
+| P1 | pose frames, vital waveforms, identity observations, recordings | prohibited |
+| P2 | occupancy count, bounded activity/fall possibility, anomaly score | permitted when policy allows |
+| P3 | versions, connection health, signed capability metadata | permitted |
+
+The client independently rejects forbidden raw-field names anywhere in the
+response. This is defense in depth, not a substitute for server-side
+projection. It also enforces HTTPS except for loopback tests, refuses redirects,
+uses bounded connect/total timeouts, caps responses at 1 MiB, caps the list at
+100 spaces, bounds nesting/arrays/strings, validates confidence, and rejects
+non-P2/P3 space records.
+
+Cloud-bound envelopes must preserve, when available:
+
+- tenant/workspace/site/space/device identity;
+- `messageId` and monotonic `eventSequence`;
+- `observedAt`, `expiresAt`, freshness, and connection state;
+- privacy class and semantic schema version;
+- calibrated confidence and explicit uncertainty/abstention;
+- model, HomeCore, hardware-manifest, calibration, evidence, and witness
+  provenance.
+
+Provenance is never used as a calibration identifier. Missing confidence,
+calibration, timestamp, or tenant identity stays missing and cannot satisfy an
+admission rule.
+
+### 6. No feedback laundering or false corroboration
+
+A Spaces record derived from RuView evidence carries derivation lineage. If it
+returns to RuView or Autogenous, it is a **projection/recollection** of that
+lineage, not a new observation. It cannot:
+
+- increment corroborating-sensor count;
+- raise evidence level;
+- be fused as an independent modality;
+- reset freshness to retrieval time;
+- erase abstention, contradiction, or uncertainty;
+- generate a second belief that cites the first as support.
+
+Deduplication keys include tenant, source/witness identity, message ID, and
+sequence. Cycles are detected and rejected. Independent corroboration requires
+a distinct authenticated source and evidence chain.
+
+### 7. Persistent memory is tenant-scoped and explanation-oriented
+
+RuVector indexes accepted semantic state under at least:
+
+```text
+(tenant_id, workspace_id, site_id, space_id, schema_version, time_bucket)
+```
+
+It stores bounded semantic features, uncertainty, evidence references, and
+witness digests. It does not store OAuth/API credentials or prohibited raw
+payloads. Retrieval always applies the authenticated tenant/workspace filter
+before similarity ranking.
+
+An anomaly explanation names:
+
+- the current semantic state and its uncertainty;
+- the relevant learned baseline/window from ADR-312;
+- comparable tenant-local history;
+- the measured deviation and contradictory evidence;
+- the provenance/witness chain;
+- the evidence label (`MEASURED`, `SYNTHETIC`, or `CLAIMED`).
+
+Memory supplies context, not permission. A historically common action is not
+automatically authorized.
+
+### 8. Agents observe and recommend; policy authorizes action
+
+Autogenous and other agents receive read-only spatial context by default. Their
+normal outputs are observations, explanations, proposals, and recommendations.
+
+Any consequential action must cross the ADR-321 `ruview-policy` gate with:
+
+- an exact action class and target;
+- a fresh capability certificate;
+- KNOWN/DEGRADED/UNKNOWN domain state;
+- bounded uncertainty and sufficient evidence;
+- tenant/workspace authorization;
+- expiry, nonce, idempotency key, and replay protection;
+- required human/policy approval;
+- a terminal witness receipt for allow or deny.
+
+Missing policy, unknown action class, stale state, incomplete provenance, or an
+unavailable approval service denies. OAuth `spaces:read` can never authorize an
+action. This ADR adds no actuator method to the Spaces client.
+
+## Implementation
+
+### RuView
+
+- `ruview-cognitum-spaces` is a reusable, read-only client with typed/redacted
+  credentials and a bounded response decoder.
+- `wifi-densepose login --spaces` explicitly requests `spaces:read` through the
+  existing PKCE flow and credential store.
+- `wifi-densepose spaces` refreshes OAuth through the existing single-flight,
+  persist-before-return mechanism, verifies that the stored grant contains
+  `spaces:read`, and lists validated state. `COGNITUM_SPACES_API` remains an
+  explicit compatibility path.
+- the dependency-free contributor metaharness adds `spaces` /
+  `ruview_spaces_list`, invokes only the OAuth branch, bounds and revalidates
+  child output, fixes the production API origin, strips the API-key compatibility
+  environment, requires an installed binary, and default-denies MCP access
+  without `credential-use`.
+
+### Cognitum Identity
+
+- the `ruview` public client allow-list includes `spaces:read`;
+- RFC 8414 metadata advertises it;
+- refresh preserves the originally granted scope;
+- no new client secret or password grant is introduced.
+
+### Cognitum API
+
+- the gateway preserves caller OAuth through an internal, spoof-resistant
+  relay while authenticating the private Function hop;
+- Spaces verifies the signed OAuth principal and queries by tenant + workspace;
+- legacy API-key behavior remains available;
+- bounded semantic-state `PUT` is available only to an explicitly scoped API-key
+  publisher and is not exposed by the RuView OAuth client;
+- OpenAPI documents both alternatives and RFC 9728 metadata supports discovery;
+- the Function remains gateway-only at Cloud Run IAM.
+
+### Autogenous
+
+Autogenous must consume an explicitly typed credential. It must not imply that
+`/v1/cli/session/exchange` produces a RuView-audience token: that exchange
+currently produces `client_id=cognitum-cli` and cannot pass the Spaces policy.
+An external RuView PKCE token may be supplied after activation, or a scoped API
+key may be used as the compatibility path. Response validation and lineage
+rules in this ADR apply before agent belief formation.
+
+## Threat model
+
+| Threat | Required control |
+|---|---|
+| Direct Function bypass | invoker IAM check; gateway SA only; no `allUsers` |
+| Forged internal OAuth header | strip inbound relay headers; gateway writes after route classification |
+| Token substitution | ES256/JWKS plus exact issuer, audience, client, type, scope, and tenant claims |
+| Cross-tenant enumeration | principal-derived Firestore selector; bounded non-enumerating errors |
+| Redirect/token exfiltration | redirects disabled; HTTPS required; fixed path |
+| Oversized/malformed response | byte/depth/count/string bounds before use |
+| Raw-data regression | server allow-list plus client forbidden-field rejection |
+| Secret disclosure | redacting types; no token logs/URLs; `.env` untracked |
+| Feedback amplification | lineage preservation, dedupe, cycle rejection, no independent corroboration |
+| Memory leakage | tenant filter before vector search; no global nearest-neighbor pass |
+| Agent overreach | observe/recommend default; ADR-321 fail-closed action gate |
+| Stale/replayed state | expiry, sequence, message ID, freshness, witness receipt |
+| JWKS outage/rotation | bounded cache; fail closed; refresh after unknown `kid`; no algorithm fallback |
+
+## Deployment and rollback
+
+Rollout order is dependency-safe:
+
+1. merge and deploy Identity scope/metadata;
+2. deploy the Spaces Function with OAuth verification while API-key behavior
+   remains unchanged;
+3. deploy the gateway relay and protected-resource metadata;
+4. verify gateway API-key access, OAuth denial matrices, direct-origin platform
+   denial (`401` or `403` before application code), and tenant isolation;
+5. merge/release the RuView client and CLI activation;
+6. enable Autogenous consumption only after its strict validation/lineage gates
+   pass.
+
+Rollback disables OAuth advertisement/relay and returns clients to scoped API
+keys. It must not restore public Function invocation. Revoking an OAuth session
+or API key must not alter paired-site state.
+
+## Validation and acceptance
+
+Required automated gates:
+
+- Identity: metadata test, migration application, PKCE authorize/token/refresh
+  scope preservation, cross-client scope denial;
+- API Function: valid claim matrix and rejection for wrong issuer/audience/
+  client/type/scope/tenant, API-key regression, tenant query assertion, bounded
+  projection tests, build and dependency audit;
+- gateway: spoofed relay stripped, caller OAuth preserved, Google hop identity
+  substituted, OpenAPI security alternatives, RFC 9728 metadata, build and
+  dependency audit;
+- RuView: semantic decoder bounds/privacy tests, redaction tests, login scope
+  tests, CLI compile, and live empty/non-empty response tests without fixtures
+  masquerading as production;
+- policy: no Spaces read can invoke an actuator; denial receipts are witnessed.
+
+Production readback must prove:
+
+- unauthenticated gateway request returns `401`;
+- legacy scoped API key returns the authenticated tenant list;
+- valid RuView OAuth returns only its workspace;
+- wrong client, missing `spaces:read`, setup/workload token, and second-tenant
+  token are denied;
+- the direct Function origin is rejected by the Google platform with `401` or
+  `403` before application code, even with a valid application credential;
+- response remains `no-store` and excludes P0/P1;
+- no secret appears in logs, diffs, artifacts, or issue/PR text.
+
+Performance, detection quality, and action-safety numbers are not claimed by
+this decision. Any such number requires a named reproducer and the repository's
+evidence labels. An empty production tenant is a successful isolation/read-path
+test, not sensing-quality evidence.
+
+## Production evidence (2026-08-18)
+
+The bounded Spaces read slice and RuView activation path are deployed. The exact
+production release chain is:
+
+- Spaces run `32148530629`, revision `spacesapi-00003-xij`, source
+  `fc333e634cd918b9d6fdde4eecbe7beac1043ab8`, Node 22, runtime service account
+  `spacesapi-runtime@cognitum-20260110.iam.gserviceaccount.com`, with
+  `apigateway-sa@cognitum-20260110.iam.gserviceaccount.com` as sole invoker;
+- gateway run `32151485401`, revision `apigateway-00180-peh`, source
+  `c4e99ebb4ce0d4e1407f435f905621476c1f0166`, image digest
+  `sha256:bacb81281a54256ff6fdaac253175e76ce6fc225f399163ca0a807a2839bd6a3`;
+- Identity run `32163542502`, revision `identity-00052-fid`, source
+  `fb6320827b879e481cad6caf184d3cbccd8279c4`, image digest
+  `sha256:0cd5896518bd8ecf042d2f3e9aea58a32e65a68dbddaab1e54f8ae6da2bfab06`,
+  and runtime service account
+  `identity-runtime-prod@cognitum-20260110.iam.gserviceaccount.com`.
+
+The live API-key matrix returned `200` with an empty bounded list,
+`Cache-Control: private, no-store`, and no prohibited P0/P1 projection fields.
+No credential returned `401`. A direct-origin request received a Google
+Frontend Bearer challenge (`401`) before application code.
+
+Two independent RuView Authorization Code + PKCE principals also passed the
+live matrix. Each token used ES256, exact issuer/audience/client checks,
+`sensing:read spaces:read`, signed UUID organization/workspace claims, refresh
+rotation, and revocation. Each gateway read returned `200`, an empty bounded
+list, and `private, no-store`; a corrupted signature returned `401`; and the
+principals had distinct pseudonymous tenant/workspace fingerprints. This proves
+the production empty-tenant behavior and independent claim binding. Non-empty
+cross-tenant isolation remains emulator/staging evidence because production was
+not mutated to manufacture a fixture.
+
+Identity metadata deliberately advertises `spaces:read` for RuView but not
+`spaces:write`. The deployed semantic-state `PUT` remains an API-key-only
+publisher surface. RuView therefore has no OAuth write, command, policy-approval,
+or actuator capability.
+
+That receipt was for the initial flat Space slice. The following production
+expansion supersedes only its hierarchy/event/alert deferral. MQTT, commands,
+actuators, real-hardware accuracy, and the long-duration operational trial
+remain outside the completed claim.
+
+## Completed implementation and production expansion (2026-08-19)
+
+- Cognitum API PRs #211 and #212 shipped the eight `/v1/spatial` collections,
+  transactional hierarchy integrity, stable pagination, event/alert retention,
+  strict P2/P3 admission, API-key-only writes, OAuth/API-key reads, and the
+  additive-only Firestore release authority. Function run `32279092861`
+  promoted active Node 22 revision `spacesapi-00005-kaf`.
+- Edge PRs #214, #215, and #216 preserved canonical UUID routing, kept SQLi
+  denial, and removed secret-valued API-key rate selection. Gateway run
+  `32284410107` promoted the reviewed immutable digest to 100% production
+  traffic. Every versioned collection returned HTTP 200 through the public
+  edge; the hierarchy composite index is `READY` and both retention TTL fields
+  are `ACTIVE`.
+- The dedicated RuView service credential was rotated to exactly
+  `spaces:read` and `spaces:write`; its predecessor returns 401. A non-mutating
+  invalid-body probe reached write validation without persisting customer data.
+  Other potentially affected owner keys and residual log retention remain
+  tracked in Cognitum API #217.
+- A live RuView Authorization Code + S256 PKCE consent requested exactly
+  `sensing:read spaces:read`. Its in-memory token read versioned `sites` with
+  HTTP 200 and schema `1.0`; the verifier then revoked the temporary refresh
+  credential and persisted no token.
+- RuView PR #1650 merged `ruview-cognitum-spaces`,
+  `ruview-spatial-memory`, the ADR-327 policy extension, CLI paging, and the
+  guarded `ruview_spaces_list` metaharness surface. PR #1651 removed stale
+  feature-branch guidance and refreshed the signed package manifest.
+- The contributor metaharness fixes the API origin, accepts bounded resource,
+  limit, and opaque-cursor inputs, strips API-key compatibility authority over
+  MCP, invokes only the hardened OAuth CLI, and rejects raw sensing or malformed
+  hierarchy/event/alert output. Its test, security, reviewed-brain, flywheel,
+  manifest, audit, exact-tarball, and claim-check gates pass.
+- Release run `32286297277` rebuilt and smoke-tested the exact package and
+  provenance-published `@ruvnet/ruview` 0.5.0. The public npm registry resolves
+  0.5.0 as `latest`; no workstation publish was used.
+- `ruview-spatial-memory` keeps one RuVector HNSW index per authenticated
+  tenant/workspace with replay, derivation, retention, cascading-erasure,
+  bounded-explanation, encrypted-snapshot, and reload-verified rotation gates.
+  This is local `SYNTHETIC` evidence, not a production sensing claim.
+- `ruview-policy` keeps observe/recommend/execute intents distinct, requires
+  exact host grants plus signed approval for consequence, rejects nonce replay,
+  and emits signed hash-chained receipts. `spaces:read` is explicitly denied as
+  execution authority.
+- Focused Rust gates and the Linux workspace/CLI/security lanes pass. Earlier
+  Windows whole-workspace attempts ended in host compiler failure or timeout;
+  those attempts are not reclassified as green evidence.
+- No OAuth write/action scope, actuator callback, MQTT deployment claim, sensing
+  accuracy claim, or real-hardware claim is introduced.
+
+## Consequences
+
+### Positive
+
+- One Cognitum identity can explicitly activate RuView's cloud spatial read
+  capability without sharing a long-lived static bearer.
+- Tenant and workspace become cryptographically bound inputs to the data query.
+- RuView and Autogenous gain useful spatial context without importing raw RF or
+  inventing independent evidence.
+- The design keeps a path for RuVector-grounded explanations and separately
+  governed action without treating either as part of the deployed read slice.
+- The direct-origin bypass is closed permanently, independent of OAuth rollout.
+
+### Costs and limitations
+
+- Two credential types coexist during migration and must stay visibly distinct.
+- OAuth depends on Identity JWKS availability and correct key rotation.
+- Production exposes both the legacy Space twins and the versioned hierarchy,
+  anonymous entities, semantic events, and alerts over HTTPS. MQTT remains a
+  design contract without deployment evidence.
+- OAuth workspace IDs will return only documents populated with `workspaceId`;
+  legacy owner-only documents require an explicit migration, never a broad query.
+- The RuView client exposes no write, command, or agent execution surface. The
+  separate API-key semantic-state ingress is neither OAuth activation nor
+  actuator authority.
+
+## Alternatives considered
+
+**Keep API keys only.** Rejected as the target: keys are useful for service
+compatibility but do not provide user activation, consent, short lifetime, or
+refresh/revocation semantics.
+
+**Treat the CLI API-key exchange token as a Spaces OAuth token.** Rejected: it
+is minted for `cognitum-cli`, not `ruview`, and accepting it would remove the
+audience/client boundary.
+
+**Trust the gateway without verifying OAuth in Spaces.** Rejected: hop identity
+and user authorization are distinct, and authorization must remain valid if the
+route topology changes.
+
+**Make Spaces state independent corroboration.** Rejected: it is derived from
+the same RuView/HomeCore lineage and would double-count evidence.
+
+**Allow agents to execute from `spaces:read`.** Rejected: read consent is not
+action authority, and perception confidence alone cannot authorize consequence.
+
+**Synchronize raw RF for better cloud models.** Rejected by default: it violates
+the edge privacy boundary and is unnecessary for the semantic product.

+# ADR-326: Tenant-scoped RuVector spatial memory and anomaly explanations
+
+- **Status**: Accepted — implementation complete; repository-wide and deployment gates pending
+- **Date**: 2026-08-19
+- **Decision owners**: RuView maintainers
+- **Extends**: ADR-312, ADR-319, ADR-325
+- **Implements**: ruvnet/RuView#1640
+- **Tags**: cognitum-spaces, ruvector, memory, tenant-isolation, explanation, privacy
+
+## Context
+
+ADR-325 requires anomaly explanations grounded in tenant-local spatial history,
+but the deployed client only returns a current list. A global vector index would
+be unsafe: filtering nearest-neighbor results after the search can reveal that a
+different tenant has a close match, even when identifiers are removed. A memory
+record can also launder returned RuView-derived state into a second independent
+observation, reset freshness, or form circular evidence.
+
+Spatial memory must be useful without storing OAuth/API credentials, raw CSI/CIR,
+RF tensors, pose frames, vital waveforms, recordings, identity observations, or
+unbounded agent transcripts. Persistence also needs explicit retention,
+deletion, provenance, and key-rotation behavior.
+
+## Decision
+
+### 1. Partition before similarity
+
+`ruview-spatial-memory` owns a `SpatialMemory` map keyed by the exact authenticated
+`(tenant_id, workspace_id)` pair. Each partition owns its own RuVector HNSW index.
+Ingest and search resolve the partition first; no global ANN query exists. Site,
+space, schema version, and time-window constraints narrow within the selected
+partition before results are returned.
+
+### 2. Bounded semantic records
+
+An accepted record contains:
+
+- tenant/workspace/site/space and stable record identity;
+- source ID, message ID, record ID, monotonic event sequence, schema version;
+- original `observed_at`/`expires_at` and a retention deadline;
+- a bounded finite semantic feature vector, uncertainty, and evidence label;
+- provenance and witness digests, plus bounded derivation references;
+- explicit observation/inference classification.
+
+Credentials and P0/P1 fields have no representation in the type. Strings,
+features, references, record counts, and query `k` are bounded. Non-finite
+features and uncertainty fail closed.
+
+### 3. Lineage and replay
+
+The partition rejects:
+
+- changed reuse of `(source_id, message_id)`;
+- a non-increasing sequence for the same source;
+- duplicate derivation references;
+- self-reference, missing/forward parents, and therefore every cycle;
+- expired input or a provenance/witness substitution.
+
+A recollection keeps its original lineage, timestamp, uncertainty, and evidence
+label. It cannot increment corroborating-source count or become independent
+support for its own ancestor.
+
+### 4. Persistent encrypted storage
+
+Snapshots are encrypted with XChaCha20-Poly1305 under a caller-supplied 256-bit
+key and a non-secret key ID. The authenticated associated data binds the storage
+format and key ID. The envelope is bounded and versioned; plaintext spatial
+records are never written to disk. Loading requires a keyring containing the
+named key. Rotation decrypts with the old key, atomically creates a new
+generation under the new key ID, reload-verifies that generation, and leaves
+the source intact. Snapshots never overwrite an existing path implicitly.
+
+Deletion supports a tenant/workspace partition, a record, and retention cutoff.
+Every deletion rebuilds that partition's HNSW index so removed records cannot be
+returned from stale graph nodes.
+
+### 5. Explanations
+
+`explain` compares a bounded query vector with nearest tenant-local history and
+returns the exact authenticated partition, generation time, ordered record IDs,
+RuVector distances, original uncertainty/evidence labels, and provenance/witness
+digests. Its basis explicitly says that similarity is not causation. The API
+does not expose the vectors or invent a causal explanation.
+
+History provides context, not authority. An explanation cannot authorize an
+action, increase certificate class, or replace a policy decision.
+
+## Consequences
+
+### Positive
+
+- Cross-tenant ANN leakage is structurally unavailable.
+- Explanations cite the exact tenant-local records used.
+- Replay/cycle/provenance substitution are rejected before indexing.
+- Encrypted persistence has explicit key IDs and rotation behavior.
+
+### Costs and limitations
+
+- Partition-local HNSW uses more indexes than a global graph.
+- Deletes and key rotation rebuild indexes.
+- No detection-quality or latency claim is made; tests are `SYNTHETIC` unless a
+  reproducer explicitly marks a measurement.
+- Cloud Cognitum does not receive the local encrypted memory file.
+
+## Validation
+
+- cross-tenant and cross-workspace nearest-neighbor denial;
+- duplicate record/message, stale-sequence, self/duplicate/missing-parent, and
+  provenance-substitution tests;
+- expiry, retention deletion, whole-partition deletion, sealed round-trip,
+  tamper rejection, wrong-key rejection, and key-rotation tests;
+- explanation citations and retained evidence/provenance labels;
+- no forbidden raw-field or credential representation;
+- the focused `ruview-spatial-memory` crate suite passes with `SYNTHETIC`
+  evidence on 2026-08-19;
+- the whole-workspace Windows gate was non-terminal (compiler crash in parallel,
+  timeout when serialized), so Linux CI, a RustSec advisory scan, and package
+  review remain release gates.
+
+## Alternatives considered
+
+**One global HNSW followed by filtering.** Rejected: ranking itself crosses the
+tenant boundary.
+
+**Cloud vector memory.** Rejected as the default: it expands the privacy and
+credential boundary without being needed for local explanations.
+
+**Plain JSONL persistence.** Rejected because tenant spatial history is sensitive
+even when raw sensing is excluded.

+# ADR-327: Governed action intents, approvals, replay protection, and witness receipts
+
+- **Status**: Accepted — implementation complete; repository-wide and deployment gates pending
+- **Date**: 2026-08-19
+- **Decision owners**: RuView maintainers
+- **Extends**: ADR-318, ADR-319, ADR-321, ADR-325
+- **Implements**: ruvnet/RuView#1641
+- **Tags**: policy, governed-action, approval, idempotency, witness, cognitum-spaces
+
+## Context
+
+The current `ruview-policy` crate evaluates assurance for an action class, but it
+does not define a complete action intent, tenant/workspace binding, policy
+version, approval, nonce/idempotency replay behavior, or signed terminal receipt.
+An agent recommendation can therefore be mistaken for execution authority, and
+`spaces:read` could be accidentally treated as a general capability.
+
+The system needs a framework that can prove why an action was allowed or denied
+without adding any actuator. Real actuation remains a separate integration and
+requires its own threat model and device evidence.
+
+## Decision
+
+### 1. Typed intent and registered policy
+
+A governed `ActionIntent` binds:
+
+- intent ID, tenant, workspace, action name/class, and exact target;
+- requested policy version and parameter/evidence digests;
+- creation/expiry, replay nonce, and requesting principal;
+- the recommendation/explanation that motivated review, never a hidden command.
+
+The gate accepts only a registered action policy. Unknown action, action-class
+mismatch, policy-version mismatch, target mismatch, invalid timestamps, and
+missing exact host authority deny before assurance is evaluated. Tenant and
+workspace are part of the signed intent/receipt and nonce key. `spaces:read` is
+explicitly tested as insufficient for an `alerts:execute` rule.
+
+### 2. Assurance and approval
+
+The existing ADR-321 certificate/domain/uncertainty/evidence gate remains the
+assurance authority. The registered policy declares a bounded minimum of
+distinct enrolled approvers. An absent, rejected, duplicated, expired,
+wrong-intent, wrong-policy-version, or unverifiable approval denies. Approval
+resolution fails closed.
+
+Agents observe, explain, or recommend by default. `evaluate` returns a decision
+receipt; it does not call an actuator. An executor may consume an `allow` receipt
+only if a separate adapter verifies the receipt, target, expiry, and its own
+device-specific authority.
+
+### 3. Replay and idempotency
+
+The bounded in-memory gate stores terminal receipts by intent ID and tracks
+nonces by `(tenant, workspace, nonce)`.
+
+- exact intent replay returns the original terminal receipt;
+- changed reuse of an intent ID returns a fail-closed idempotency error;
+- reuse of a nonce by another intent returns a fail-closed replay error;
+- expired intents and approvals deny;
+- failed or denied attempts are terminal and auditable.
+
+The current state store is bounded and in-memory, intended for local/runtime use
+rather than cross-process replay protection. A production executor must place
+the same intent/nonce/receipt invariants behind a transactional durable store;
+this ADR does not claim that adapter exists.
+
+### 4. Witnessed terminal receipt
+
+Every evaluated observe/recommend/execute request produces a canonical receipt
+containing the intent digest, decision/reason, policy version, tenant/workspace,
+decision/expiry time, intent ID and nonce, approval count, and previous receipt
+digest. The receipt is signed through the `ruview-attest` signer interface and
+can be independently verified. Hash chaining makes removal/reordering visible.
+Malformed input, ID conflict, nonce replay, capacity exhaustion, and sequence
+exhaustion are errors before receipt creation and must be audited by the host.
+
+The reference keyed-BLAKE3 signer remains `SYNTHETIC` evidence only, as documented
+by ADR-319. Production asymmetric signing and key custody must be supplied by the
+deployment adapter; no symmetric test MAC is represented as hardware identity.
+
+## Consequences
+
+### Positive
+
+- Recommendation, authorization, and execution are distinct typed stages.
+- Default-deny covers missing policy, stale evidence, unavailable approval, and replay.
+- Every decision has a terminal, verifiable explanation.
+- `spaces:read` cannot silently expand into consequence.
+
+### Costs and limitations
+
+- Executors must implement a separate receipt-verifying adapter.
+- Distributed replay protection needs a transactional durable store.
+- This ADR implements no actuator, command transport, pairing mutation, or device control.
+- Simulator tests are not hardware validation.
+
+## Validation
+
+- unknown/missing policy, stale intent, policy-version/target mismatch,
+  insufficient authority, and `spaces:read`-only denial;
+- certificate/domain/uncertainty/evidence denial matrix from ADR-321;
+- missing/rejected/expired/duplicate/wrong-intent approval tests;
+- exact idempotent replay, changed reuse, nonce replay, and bounded-store tests;
+- receipt signature, canonical digest, chain linkage, and tamper rejection;
+- tests proving evaluation exposes no actuator callback or network/file side effect.
+
+The focused `ruview-policy` suite passes on 2026-08-19. The reference signer
+tests are `SYNTHETIC`; they are not hardware-identity evidence. The non-terminal
+whole-workspace Windows gate still requires authoritative Linux CI evidence.
+
+Any future actuator adds a separate ADR, credential boundary, failure/rollback
+plan, allow/deny integration tests, and captured target-device evidence.
+
+## Alternatives considered
+
+**Let agents call actuators after a recommendation.** Rejected: recommendation
+quality is not authorization.
+
+**Treat OAuth scopes as action policy.** Rejected: `spaces:read` expresses read
+consent only and carries no target-specific assurance or approval.
+
+**Emit receipts only for successful actions.** Rejected: denial and unavailable
+approval are security-relevant terminal facts.

+# ADR 340: iPhone LiDAR Sensor Bridge
+
+Status: Proposed
+
+## Context
+
+RuView needs a low cost mobile geometry sensor that can contribute calibrated spatial observations without coupling the perception substrate to Apple frameworks.
+
+ARKit exposes rear LiDAR scene depth through `ARFrame.sceneDepth` and `smoothedSceneDepth` on supported devices. Ordinary mobile web pages do not receive this ARKit depth surface directly, so native capture and web visualization must be separated.
+
+## Decision
+
+Use a two layer architecture.
+
+1. Native Swift and ARKit perform acquisition.
+2. A modality neutral wire frame transports geometry into browser tools and, next, the RuView HAL.
+
+The native client will capture depth, confidence, camera intrinsics, and world tracking pose. RGB imagery is excluded from the default transport.
+
+The protocol identifier is `ruview.lidar.depth.v1`.
+
+Depth samples are quantized to UInt16 millimeters for transport. Confidence remains UInt8. The default sender downsamples by two spatially and caps transmission at 15 FPS. Full fidelity depth remains available locally for future on device inference.
+
+## RuView integration boundary
+
+The transport must not become a second world model. The production receiver converts each packet into the canonical `ruview-hal::Observation`, then passes it through authenticated sensor identity, provenance, OOD gating, uncertainty aware fusion, spatial memory, and WorldGraph adapters.
+
+Rules:
+
+1. `source=live` is valid only for frames produced by an active ARKit session.
+2. Sequence numbers are monotonic per sensor session.
+3. Wall clock timestamp is separate from ARKit monotonic frame timing.
+4. RGB is off by default and requires an explicit higher privacy capability.
+5. Browser clients consume geometry but are not treated as authoritative sensors.
+6. Unsupported devices fail closed rather than substituting simulated depth.
+
+## Performance target
+
+`[SYNTHETIC]` A 256 x 192 Float32 depth map is about 196 KB before confidence and metadata. Downsampling to 128 x 96 and encoding each sample as two byte depth plus one byte confidence yields about 36.9 KB raw. At 15 FPS the raw sensor payload is about 553 KB/s. Base64 raises this to roughly 737 KB/s before JSON metadata. These values are arithmetic sizing estimates, not device measurements.
+
+The `[CLAIMED target]` for local network latency is below 150 ms p95. A later binary WebSocket or QUIC transport can remove base64 overhead; the exact end-to-end reduction must be measured before it is claimed.
+
+## Security
+
+The development relay is LAN-facing, requires a random per-run bearer token, bounds message size, and restricts the files it serves. Its default `ws://` transport is not encrypted, so it is not a production trust boundary.
+
+Production requires WSS, authenticated sensor identity, replay protection, message size limits, per tenant authorization, provenance receipts, and explicit retention policy before persistence.
+
+## Consequences
+
+Benefits include commodity hardware, metric depth, tracked camera pose, rapid room scanning, calibration support for RF sensing, and a practical ground truth source for RuView experiments.
+
+The main limitation is that Apple provides processed scene depth rather than the underlying raw transient LiDAR waveform. Therefore this implementation supports direct geometry and sensor fusion now, but does not reproduce research systems that require raw multipath time of flight transients for non line of sight reconstruction.
+
+## Acceptance criteria
+
+A physical LiDAR capable iPhone must stream live geometry to the browser viewer with monotonically increasing sequence numbers, no RGB payload, valid confidence maps, and below 150 ms p95 local network latency over a 60 second run.
+
+CI type-checking and simulator runs do not satisfy this criterion. Until a captured physical-device run records the environment and results, the hardware behavior and latency remain unverified.

+# ADR-344: Adaptive local installation discovery
+
+## Status
+
+Accepted — local advertisement and mobile discovery implemented; physical
+peer-link and hosted-relay qualification pending.
+
+## Context
+
+RuView installations previously depended on a manually stored IP address.
+DHCP changes, access-point changes, and client isolation could therefore leave
+a healthy sensing installation unreachable from the mobile app. Repeated
+authentication-policy log entries did not prove that the selected endpoint was
+reachable.
+
+Discovery must make commissioning recoverable without turning a service name
+into authentication, leaking sensor data, scanning arbitrary subnets, or
+silently moving private spatial data to a hosted service.
+
+## Decision
+
+The sensing server advertises one bounded `_ruview._tcp.local.` service when it
+is bound to a routable interface. Loopback-only instances do not advertise,
+and operators can disable advertisement with `--no-mdns`.
+
+The TXT contract is deliberately small:
+
+| Key | Required | Meaning |
+|---|---:|---|
+| `schema=ruview.installation.v1` | yes | Fail-closed protocol discriminator |
+| `tls=0|1` | yes | HTTP or HTTPS origin construction |
+| `installation=<opaque id>` | no | Bounded routing hint, never authentication |
+
+The advertisement contains no node inventory, room identifier, SSID,
+credentials, CSI, vital estimates, pose, identity, or learning data. The
+hostname is bounded and sanitized before registration. Advertisement failure
+is recoverable and does not stop sensing.
+
+RuView Mobile resolves only the matching service and schema, validates the
+resulting origin under its private-LAN/HTTPS policy, and requires an application
+health probe before selection. Its adaptive broker retains the configured
+origin preference and requires two failed configured probes plus two healthy
+fallback probes before switching. Credentials remain scoped to their saved
+origin.
+
+The recovery ladder is:
+
+1. configured private-LAN or HTTPS origin;
+2. verified Bonjour local origin;
+3. physically qualified Apple peer-to-peer local path;
+4. explicit, authenticated HTTPS relay for bounded derived frames only;
+5. optional administrator-managed WireGuard/Tailscale access.
+
+Only levels 1 and 2 are implemented and software-validated by this decision.
+Peer-to-peer browsing is enabled on Apple platforms, but it is not a qualified
+peer-link data plane. This repository does not provide a hosted relay and must
+fail closed when no local endpoint is healthy.
+
+## Security and privacy consequences
+
+- Service discovery is routing evidence, not installation authentication.
+- Public HTTP origins, credentials in URLs, malformed records, and records with
+  the wrong schema are rejected before use.
+- Raw CSI, RSSI streams, camera/LiDAR frames, room geometry, pose labels,
+  identity data, and training examples remain local.
+- Future relay work requires a separate consent, authentication, revocation,
+  minimization, and physical evidence review.
+- ESP32-S3/C6 nodes remain provisioned to the sensing installation. This ADR
+  does not claim direct phone-to-node discovery or invent a firmware protocol.
+
+## Validation
+
+Software acceptance requires:
+
+- unit tests for bounded advertisement construction and hostname sanitation;
+- mobile parser rejection, route scoring, anti-flapping, and Settings UI tests;
+- Rust, TypeScript, lint, security, metaharness, Expo, and native compile gates;
+- a real Bonjour resolve of the TXT contract followed by a successful
+  `/api/v1/status` probe.
+
+Physical qualification additionally requires installation discovery on an
+iPhone, live frame and node-inventory receipt, DHCP-change recovery without
+flapping, and a five-to-ten-minute zero-fusion-error burn-in. Simulator and
+host-only results remain `MEASURED_SOFTWARE`; peer-link, relay, and physical
+reconnection claims remain `NOT_MEASURED` until those captures exist.

+- The default dependency graph is checked to exclude Burn, Rapier, Tch, and

+- Burn CPU serialization/inference tests pass on the authoring host only with
+  Cargo's `--ignore-rust-version`; the resolved CubeCL graph requires Rust 1.92.
+  The workspace file pins Rust 1.89 and the host provides Rust 1.91.1. This is
+  diagnostic, not release approval.
+- `cargo audit 0.22.1` used RustSec database commit
+  `69f93cf294852cfa9b53751f4ca86de3283dd290` (feed timestamp 2026-08-12).
+  ADR-323 updates remove resolved advisories in `event-listener`, `rkyv`, and
+  `wasmtime`. The workspace still has five advisories in pre-existing
+  `quick-xml` and `rsa` dependency paths; the default physics graph contains
+  none of them. The optional Burn training graph includes yanked `spin 0.9.8`.
+- `cargo-deny` is not installed on the authoring host, so the required license
+  and policy gate is not claimed complete.
+- Strict Clippy passes with warnings denied for core/physics default and
+  dynamics builds, the diagnostic learned-CPU build, and the Cog itself with
+  dependency linting excluded. Focused core, physics, dynamics, learned, Cog,
+  sensing-server adapter/live-audit/HTTP, schema, golden, strict-split,
+  feature-boundary, and fuzz-build checks pass.
+- The repository-wide rustfmt gate is already red across unrelated crates. The
+  sensing-server library has existing warning debt, and unscoped Cog Clippy is
+  blocked by existing `wifi-densepose-ruvector` warnings. The prescribed
+  `cargo test --workspace --no-default-features` did not reach a terminal result
+  in either a 904-second cold or 604-second warm serial run on this Windows
+  host. None of these broader gates is represented as green.

+### Cognitum Spaces activation
+
+Cognitum Spaces gives RuView a tenant/workspace-scoped semantic world model
+without uploading raw RF/CSI, recordings, pose frames, vital waveforms, or
+identity observations. It represents sites, buildings, floors, bounded
+rooms/spaces, zones, anonymous entities, semantic events, and alerts.
+
+Activate the public RuView OAuth client with Authorization Code + PKCE:
+
+```bash
+wifi-densepose login --spaces
+wifi-densepose whoami
+wifi-densepose spaces --resource sites --limit 50
+wifi-densepose spaces --resource events --limit 25
+```
+
+The login requests `sensing:read spaces:read`. That consent is read-only: it
+does not grant publication, pairing, policy approval, command, or actuator
+authority. Versioned collections are `sites`, `buildings`, `floors`,
+`spaces`, `zones`, `entities`, `events`, and `alerts`. A returned
+`nextCursor` is opaque and valid only for the same collection.
+
+The dependency-free contributor harness exposes the same read path:
+
+```bash
+npx @ruvnet/ruview@0.5.0 spaces --resource alerts --limit 25
+npx @ruvnet/ruview@0.5.0 mcp start
+```
+
+Its MCP tool is `ruview_spaces_list`. MCP reads are OAuth-only, use the fixed
+Cognitum API origin, and require the explicit guarded-tool opt-in. The harness
+does not accept an arbitrary credential path or API origin.
+
+For service compatibility, `wifi-densepose spaces` can read
+`COGNITUM_SPACES_API` at request time. API-key access to a versioned collection
+also requires `--workspace <uuid>`; OAuth derives the workspace from the
+signed token. Never print or commit either credential.
+
+Every response is bounded and revalidated. Raw-sensing aliases, malformed
+hierarchy, non-anonymous person/track entities, invalid timestamps, stale
+confidence, and oversized structures fail closed. Empty data means no
+authorized state is present; it does not prove that a physical site is empty.
+
+RuVector spatial memory remains physically separated by tenant and workspace.
+Agents observe or recommend by default. Any consequential execution requires a
+separate policy/grant/approval decision and produces a signed, hash-chained
+receipt; the Spaces read token can never satisfy that gate.
+
+See ADR-325, ADR-326, and ADR-327 for the activation, memory, and governed-action
+decisions.

([#509](https://github.com/ruvnet/RuView/issues/509), [#1125](https://github.com/ruvnet/RuView/issues/1125))** Yes, it runs, and the results are reproducible: the deterministic signal-pipeline proof (`python archive/v1/data/proof/verify.py`, must print `VERDICT: PASS`), the committed pose training dump (`v2/crates/cog-pose-estimation/cog/artifacts/train_results.json`), and the auditable MM-Fi arena all back specific numbers. But a single-antenna, 56-subcarrier CSI stream at a 20-frame window does *not* carry the fine-grained spatial information the multi-antenna NIC research relies on — so the shippable pose accuracy the project stands behind today is the **MM-Fi benchmark number**, not a live single-ESP32 number. The path to a first reproducible on-device baseline (PCK@20 ≥ 35%) is tracked in [ADR-079](adr/ADR-079-camera-ground-truth-training.md) / [#645](https://github.com/ruvnet/RuView/issues/645).

 ### Cross-Environment Adaptation (MERIDIAN)
 
-Models trained in one room typically lose 40-70% accuracy in a new room due to different WiFi multipath patterns. The MERIDIAN system (ADR-027) solves this with a 10-second automatic calibration:
+Models trained in one room can lose substantial accuracy in a new room because the multipath
+distribution changes. ADR-027 proposes an automatic adaptation design, and the Rust tree contains
+individual research components, but RuView does **not** currently provide a validated command that
+turns ~200 unlabeled frames into a working room adapter.
 
-1. **Deploy** the trained model in a new room
-2. **Collect** ~200 unlabeled CSI frames (10 seconds at 20 Hz)
-3. The system automatically generates environment-specific LoRA weights via contrastive test-time training
-4. No labels, no retraining, no user intervention
+Current, testable calibration is the separate **labeled** reference in
+`aether-arena/calibration/`: collect paired CSI/keypoint samples, then fit a model-specific LoRA
+adapter. The MM-Fi transformer expects `[N,3,114,10]`; the cog expects `[N,56,20]`. Neither adapter
+loads into the other model, and neither result establishes live ESP32 pose accuracy without a
+leakage-free held-out capture and mean-pose baseline.

 No. Consumer WiFi exposes only RSSI (one number per access point), not CSI (56+ complex subcarrier values per frame). RSSI supports coarse presence and motion detection. Full pose estimation requires CSI-capable hardware like an ESP32-S3 ($8) or a research NIC.
 
 **Q: How accurate is the pose estimation?**
-Accuracy depends on hardware and environment. With a 3-node ESP32 mesh in a single room, the system tracks 17 COCO keypoints. The core algorithm follows the CMU "DensePose From WiFi" paper ([arXiv:2301.00250](https://arxiv.org/abs/2301.00250)). The MERIDIAN domain generalization system (ADR-027) reduces cross-environment accuracy loss from 40-70% to under 15% via 10-second automatic calibration.
+The strongest published RuView result is the MM-Fi transformer benchmark (82.69% torso-PCK@20 on
+the matched `random_split` protocol), not a live ESP32 result. The committed cog model measured
+3.0% PCK@20 on its holdout, below the ≥35% target, and the viewer's live skeleton is a heuristic
+placeholder. No measured claim currently shows a 3-node ESP32 mesh reliably tracking 17 keypoints.
+ADR-027's 10-second unlabeled MERIDIAN adaptation is Proposed; the available measured calibration
+reference uses labeled, model-specific samples.
 
 **Q: Does it work through walls?**
 Yes. WiFi signals penetrate non-metallic materials (drywall, wood, concrete up to ~30cm). Metal walls/doors significantly attenuate the signal. With a single AP the effective through-wall range is approximately 5 meters. With a 3-6 node multistatic mesh (ADR-029), attention-weighted cross-viewpoint fusion extends the effective range to ~8 meters through standard residential walls.

+# Cognitum Spaces OAuth activation
+
+Use this playbook to activate and inspect the tenant-scoped Cognitum Spaces
+projection without giving an agent a bearer token or API key.
+
+## Boundary
+
+- This is a read-only P2/P3 semantic projection. HomeCore Edge remains
+  authoritative.
+- Raw CSI, CIR, RF tensors, recordings, pose frames, vital waveforms, and
+  identity observations are prohibited.
+- `spaces:read` grants no pairing, publication, write, command, policy approval,
+  spending, or actuator authority.
+- A read may refresh an expiring OAuth session and atomically rotate the local
+  credential file.
+
+## Activate OAuth explicitly
+
+Install or build the `wifi-densepose` CLI, then request the additional scope:
+
+```bash
+wifi-densepose login --spaces
+```
+
+For a terminal without a browser:
+
+```bash
+wifi-densepose login --spaces --no-browser
+```
+
+Confirm that the account reports `spaces:read`, then list through the
+metaharness:
+
+```bash
+wifi-densepose whoami
+npx @ruvnet/ruview spaces
+npx @ruvnet/ruview spaces --resource sites
+npx @ruvnet/ruview spaces --resource events --limit 25
+```
+
+The versioned collections are `sites`, `buildings`, `floors`, `spaces`,
+`zones`, `entities`, `events`, and `alerts`. Continue a page with the returned
+opaque `nextCursor`; do not decode or reuse a cursor for another collection.
+
+Use `--credentials-path <private-file>` only from the human-invoked CLI when a
+non-default credential store is intentional. Never put a bearer token or API
+key on the command line.
+
+## MCP
+
+The tool is `ruview_spaces_list`. It is denied by default even though the cloud
+operation is read-only, because it consumes a local identity credential and
+contacts an external service. The MCP server operator must grant that capability
+and may bind the credential path in the server environment:
+
+```bash
+RUVIEW_MCP_GRANTS=credential-use \
+RUVIEW_CREDENTIALS_PATH=/private/ruview/credentials.json \
+npx @ruvnet/ruview mcp start
+```
+
+MCP calls cannot choose a credential path and the tool schema has no token or
+API-key, workspace override, or base-URL field. The API origin is fixed to
+`https://api.cognitum.one`, the adapter requires an installed
+`wifi-densepose` binary, and the child environment excludes
+`COGNITUM_SPACES_API`, so this
+surface verifies the OAuth path rather than silently taking the compatibility
+API-key path.
+
+## Interpret results honestly
+
+An empty `data` list can be a valid authenticated tenant result. It proves the
+read path and isolation behavior, not sensing quality. Every accepted response
+must declare `HomeCore Edge` as authoritative and carry the complete prohibited
+field list. Parent lineage, schema version, anonymous person/track identity,
+event/alert fields, confidence, and cursor bounds are independently checked.
+Any malformed, oversized, non-semantic, or raw-field response fails closed.

+### Cognitum Spaces OAuth
+
+Activate the additional read scope through the Rust CLI, then use the same
+validated client through the metaharness:
+
+```bash
+wifi-densepose login --spaces
+wifi-densepose whoami
+npx @ruvnet/ruview spaces
+npx @ruvnet/ruview spaces --resource sites --limit 50
+npx @ruvnet/ruview spaces --resource events --cursor '<opaque-next-cursor>'
+```
+
+The metaharness never accepts a bearer token or API key and removes
+`COGNITUM_SPACES_API` from the child environment, so this surface cannot
+silently fall back to the compatibility API-key path. The API origin is fixed
+to `https://api.cognitum.one`, and the credentialed adapter requires an
+installed `wifi-densepose` binary rather than running Cargo build scripts from
+an auto-detected checkout. It returns only the bounded P2/P3 semantic
+projection. `--resource` selects one of `sites`, `buildings`, `floors`,
+`spaces`, `zones`, `entities`, `events`, or `alerts`; `--limit` is 1–100 and
+`--cursor` is the opaque value from the prior page. An empty list is a valid
+authenticated result, not sensing-quality evidence. An expired session may
+rotate the stored refresh credential before the read completes.
+
+MCP use is denied unless the server operator starts it with
+`RUVIEW_MCP_GRANTS=credential-use`. Set `RUVIEW_CREDENTIALS_PATH` in the MCP
+server environment when a non-default store is needed; MCP calls cannot choose
+an arbitrary credential file or URL. `spaces:read` grants no write, pairing,
+command, policy-approval, spending, or actuator authority. See the bundled
+`cognitum-spaces` skill for the full playbook.

+# Cognitum Spaces OAuth activation
+
+Use this playbook to activate and inspect the tenant-scoped Cognitum Spaces
+projection without giving an agent a bearer token or API key.
+
+## Boundary
+
+- This is a read-only P2/P3 semantic projection. HomeCore Edge remains
+  authoritative.
+- Raw CSI, CIR, RF tensors, recordings, pose frames, vital waveforms, and
+  identity observations are prohibited.
+- `spaces:read` grants no pairing, publication, write, command, policy approval,
+  spending, or actuator authority.
+- A read may refresh an expiring OAuth session and atomically rotate the local
+  credential file.
+
+## Activate OAuth explicitly
+
+Install or build the `wifi-densepose` CLI, then request the additional scope:
+
+```bash
+wifi-densepose login --spaces
+```
+
+For a terminal without a browser:
+
+```bash
+wifi-densepose login --spaces --no-browser
+```
+
+Confirm that the account reports `spaces:read`, then list through the
+metaharness:
+
+```bash
+wifi-densepose whoami
+npx @ruvnet/ruview spaces
+npx @ruvnet/ruview spaces --resource sites
+npx @ruvnet/ruview spaces --resource events --limit 25
+```
+
+The versioned collections are `sites`, `buildings`, `floors`, `spaces`,
+`zones`, `entities`, `events`, and `alerts`. Continue a page with the returned
+opaque `nextCursor`; do not decode or reuse a cursor for another collection.
+
+Use `--credentials-path <private-file>` only from the human-invoked CLI when a
+non-default credential store is intentional. Never put a bearer token or API
+key on the command line.
+
+## MCP
+
+The tool is `ruview_spaces_list`. It is denied by default even though the cloud
+operation is read-only, because it consumes a local identity credential and
+contacts an external service. The MCP server operator must grant that capability
+and may bind the credential path in the server environment:
+
+```bash
+RUVIEW_MCP_GRANTS=credential-use \
+RUVIEW_CREDENTIALS_PATH=/private/ruview/credentials.json \
+npx @ruvnet/ruview mcp start
+```
+
+MCP calls cannot choose a credential path and the tool schema has no token or
+API-key, workspace override, or base-URL field. The API origin is fixed to
+`https://api.cognitum.one`, the adapter requires an installed
+`wifi-densepose` binary, and the child environment excludes
+`COGNITUM_SPACES_API`, so this
+surface verifies the OAuth path rather than silently taking the compatibility
+API-key path.
+
+## Interpret results honestly
+
+An empty `data` list can be a valid authenticated tenant result. It proves the
+read path and isolation behavior, not sensing quality. Every accepted response
+must declare `HomeCore Edge` as authoritative and carry the complete prohibited
+field list. Parent lineage, schema version, anonymous person/track identity,
+event/alert fields, confidence, and cursor bounds are independently checked.
+Any malformed, oversized, non-semantic, or raw-field response fails closed.

+# RuView iPhone LiDAR
+
+This experimental integration provides the native and browser components needed to use a LiDAR-capable iPhone as a RuView geometry sensor. The native source is type-checked against the iOS SDK in CI; physical-device validation is tracked separately below.
+
+## Architecture
+
+```text
+iPhone LiDAR
+  -> ARKit sceneDepth
+  -> depth + confidence + camera intrinsics + device pose
+  -> compact u16 millimeter wire frame
+  -> WebSocket relay
+  -> browser point cloud
+  -> future RuView HAL / fusion ingest
+```
+
+The native path is the sensor. The web path is a receiver and visualization surface. Mobile Safari does not expose ARKit scene depth directly to ordinary web pages, so the browser cannot replace the native capture layer on iPhone today.
+
+## Native iPhone path
+
+Create an iOS SwiftUI app target in Xcode, deployment target iOS 17 or newer, then add the files under `native/RuViewLiDAR/` to the target.
+
+Add this Info.plist value:
+
+```xml
+<key>NSCameraUsageDescription</key>
+<string>RuView uses the camera and LiDAR scanner to capture local depth geometry.</string>
+```
+
+Run on a physical LiDAR capable iPhone or iPad. The simulator does not provide LiDAR scene depth.
+
+The app requests `ARWorldTrackingConfiguration` with `.sceneDepth`, checks `supportsFrameSemantics`, extracts `ARDepthData.depthMap` and `confidenceMap`, and never transmits RGB camera frames.
+
+## Browser path
+
+```bash
+cd integrations/iphone-lidar/web
+npm ci
+npm test
+npm start
+```
+
+The relay prints a random per-run access token. Open the printed browser URL and set the iPhone endpoint to the printed native URL. They have this form:
+
+```text
+http://HOST:8787/?token=TOKEN
+ws://HOST:8787/ws/lidar?token=TOKEN
+```
+
+Set `RUVIEW_LIDAR_TOKEN` to supply the token explicitly. The token only prevents unauthenticated peers from joining the development relay; because `ws://` does not encrypt it, production use requires TLS and `wss://`.
+
+## Wire format
+
+Schema: `ruview.lidar.depth.v1`
+
+Depth is downsampled by 2 in each dimension by default and streamed at a maximum of 15 FPS. Each depth sample is encoded as little endian UInt16 millimeters plus one UInt8 confidence value. `[SYNTHETIC]` Arithmetic sizing reduces the depth payload from roughly 196 KB per 256 x 192 Float32 frame to roughly 37 KB per 128 x 96 frame before base64 and JSON overhead.
+
+`[SYNTHETIC]` At 15 FPS that is approximately 0.75 MB/s after base64 overhead, versus roughly 8 MB/s for uncompressed Float32 JSON at full resolution. These are sizing estimates, not device or network measurements.
+
+## Privacy and governance
+
+The initial implementation labels provenance as `source=live` and `privacyClass=geometry-only`. It sends depth geometry, confidence, camera intrinsics, pose, sequence, and wall clock timestamp. It does not send RGB imagery.
+
+The development relay requires an ephemeral token and bounds each WebSocket message, but it is not a production trust boundary. Production integration should terminate the WebSocket inside RuView, authenticate the device using the existing sensor identity path, convert each frame into `ruview-hal::Observation`, and attach witness receipts before fusion or persistence.
+
+## Validation status
+
+- `[MEASURED]` The committed Node tests cover wire decoding, malformed inputs, relay authentication, static-file restrictions, and live WebSocket forwarding.
+- `[MEASURED]` GitHub Actions type-checks the native sources with strict concurrency against the iOS 17 SDK.
+- Physical iPhone capture, end-to-end rendering, confidence-map behavior, and the latency target are not yet measured. A simulator or CI compile does not satisfy the hardware acceptance test.
+
+## Acceptance test
+
+1. Run the relay and browser viewer.
+2. Run the native app on a LiDAR capable iPhone.
+3. Start LiDAR capture and enable streaming.
+4. Move the phone through a room.
+5. Verify the browser shows a changing point cloud, sequence increases monotonically, latency stays below the `[CLAIMED target]` of 150 ms p95 on a local WiFi network, and no RGB payload is present in captured WebSocket frames.

+# ruview-offaxis
+
+Clean-room **off-axis (head-coupled) perspective projection** in Rust, with a
+wasm-bindgen surface for browser demos. Implements ADR-324.
+
+The screen becomes a window: given the physical screen's corners and the
+viewer's eye position, the crate produces the asymmetric frustum and
+screen-aligned view matrix that keep the screen plane fixed while everything
+behind and in front of it moves with true parallax.
+
+## Clean-room statement
+
+ADR-324 records that the prior-art repository (`icurtis1/off-axis-sneaker`)
+publishes **no license**. No code, assets, or derived text from it appear in
+this crate. The implementation follows the published math only:
+
+- Robert Kooima, *Generalized Perspective Projection* (2008) — the
+  `pa`/`pb`/`pc` screen-corner frustum formulation.
+- Casiez, Roussel & Vogel, *1€ Filter* (CHI 2012) — adaptive tracking-noise
+  smoothing.
+
+## What's in the crate
+
+| Module | Contents |
+|---|---|
+| `projection` | `Screen` (3 corners, any orientation), `off_axis()` → asymmetric `projection` + screen-aligned `view` matrix (column-major `f64`, the three.js `Matrix4.elements` layout). All failure modes are typed errors — never NaN matrices. |
+| `filter` | `OneEuro` / `OneEuro3` one-euro filter. Timestamps are injected; the crate never reads a clock. |
+| `rf` | `field_peak()` — strongest-cell extraction for `/ws/sensing` `signal_field` grids, mirroring the sensing server's `field_localize.rs` constants (`X_SCALE 0.6`, `Z_SCALE 0.5`, `PEAK_THRESHOLD 0.35`). `CoarseParallax` — the **Tier B** stage: deadband + gain + hard clamp + one-euro. `ScreenCalibration` — physical screen (cm) + normalized-head → metric eye mapping (**Tier A** input hook). |
+| `wasm` (wasm32 only) | `OffAxisCamera` and `RfParallax` wasm-bindgen classes. |
+
+The native core is **dependency-free**; wasm-bindgen is pulled only when
+compiling for `wasm32`.
+
+## Honesty contract (repo rule — read before demoing)
+
+- A single-link CSI field peak is a *representation of field energy*, *not*
+  metric localization and *never* a head position (see the caveat in
+  `wifi-densepose-sensing-server/src/field_localize.rs`). The Tier B path is
+  therefore **coarse body parallax by construction**: deadbanded,
+  gain-limited, hard-clamped. Do not present it as head tracking; the demo
+  labels it on screen at all times.
+- Numeric defaults (gains, deadbands, filter cutoffs) are interaction-design
+  choices — `CLAIMED`, not measured performance.
+- The benchmark numbers below are `MEASURED` with the stated reproducer on
+  the stated machine; re-run locally before relying on them.
+
+## Native quick start
+
+```rust
+use ruview_offaxis::{off_axis, Screen, Vec3};
+
+// 60 cm × 34 cm screen centered at the origin; eye 65 cm out, 10 cm right.
+let screen = Screen::centered(0.60, 0.34)?;
+let oa = off_axis(&screen, Vec3::new(0.10, 0.0, 0.65), 0.05, 100.0)?;
+let mvp: [f64; 16] = oa.view_projection(); // column-major, GL/three.js layout
+# Ok::<(), ruview_offaxis::OffAxisError>(())
+```
+
+Key invariant (unit-tested for a grid of eye positions and for tilted
+screens): the physical screen corners always project exactly to the NDC
+corners — `pa→(−1,−1)`, `pb→(1,−1)`, `pc→(−1,1)`, `pd→(1,1)` — and points on
+the screen plane are eye-invariant. That is the mathematical definition of
+"the screen is a window".
+
+## Building the WASM package
+
+Generated artifacts are not committed (repo rule). Build once:
+
+```bash
+cd v2
+rustup target add wasm32-unknown-unknown
+cargo build -p ruview-offaxis --target wasm32-unknown-unknown --release
+
+# Install the matching CLI once: cargo install wasm-bindgen-cli --version 0.2.114
+wasm-bindgen --target web --out-dir crates/ruview-offaxis/pkg \
+    target/wasm32-unknown-unknown/release/ruview_offaxis.wasm
+```
+
+Output: `pkg/ruview_offaxis.js` + `pkg/ruview_offaxis_bg.wasm`
+(≈54 KB wasm, `MEASURED` for this crate at wasm-bindgen 0.2.114; `wasm-opt -Oz`
+can shrink it further if you have binaryen). The demo at
+`examples/three.js/demos/07-off-axis-window.html` loads this path directly —
+build, then open the demo. A Node smoke test of the same flow lives in the
+PR's validation notes.
+
+## three.js integration (the whole wiring)
+
+```js
+import init, { OffAxisCamera, RfParallax } from './pkg/ruview_offaxis.js';
+await init();
+
+// Physical calibration in cm — measure your actual screen.
+const cam = new OffAxisCamera(60, 34, 65, 0.05, 100.0);
+cam.set_filter(1.2, 0.4); // one-euro: min_cutoff Hz, beta
+
+const camera = new THREE.PerspectiveCamera();
+camera.matrixAutoUpdate = false; // WASM owns every matrix
+
+const view = new THREE.Matrix4();
+function onFrame(eyeX, eyeY, eyeZ) {          // metres, screen space
+  cam.update_eye(eyeX, eyeY, eyeZ, performance.now() / 1000);
+  camera.projectionMatrix.fromArray(cam.projection());
+  camera.projectionMatrixInverse.copy(camera.projectionMatrix).invert();
+  view.fromArray(cam.view());
+  camera.matrixWorld.copy(view).invert();
+  camera.matrixWorldInverse.copy(view);
+}
+```
+
+Scene convention: the screen plane is `z = 0`; content behind the screen has
+`z < 0`; content with `z > 0` "pops out". Do **not** update `camera.aspect`
+on resize — the frustum is determined by the physical screen, not the
+viewport.
+
+### Input tiers (ADR-324)
+
+- **Tier A (fine tracker)** — feed any head tracker through
+  `cam.update_normalized(nx, ny, depthScale, lateralRangeM, t)`; `nx`/`ny`
+  are normalized image coordinates from whatever fine tracker the host runs
+  (which stays entirely in the browser). RF adds presence gating around it.
+- **Tier B (RF only, labeled)** — `RfParallax.update(Float32Array, nx, nz, t)`
+  with `/ws/sensing` `signal_field` values, then `rf.eye()` →
+  `cam.update_eye(...)`. Keep the on-screen "coarse body parallax — not head
+  tracking" label; the clamps in the Rust core bound the excursion but the
+  label is what keeps the demo honest.
+
+## Benchmarks
+
+`MEASURED` — reproducer: `cd v2 && cargo bench -p ruview-offaxis`.
+Environment for the numbers below: Linux x86_64 container (shared/virtualized
+CPU), rustc 1.89.0, criterion 0.5, 2026-08-16. Treat them as order-of-
+magnitude; re-run on your hardware.
+
+| Benchmark | Time (median) |
+|---|---|
+| `off_axis_projection` (frustum + view build) | ~76 ns |
+| `view_projection` combined (4×4 multiply) | ~27 ns |
+| `one_euro3_step` (3-axis filter step) | ~60 ns |
+| `field_peak_20x20` (live grid size) | ~488 ns |
+| `field_peak_100x100` | ~12.3 µs |
+| `tier_b_full_frame_20x20` (scan → parallax → projection) | ~598 ns |
+
+The full Tier B per-frame path costs well under a microsecond — under 0.01%
+of a 60 Hz frame budget. The argmax scan was the only hot spot found; it was
+rewritten branch-light for a measured −18% (20×20) / −33% (100×100) before
+these numbers were taken. End-to-end *motion-to-photon* latency (RF capture →
+render) has **not** been measured and is dominated by the sensing pipeline,
+not this crate; no figure is claimed.
+
+## Validation
+
+```bash
+cd v2
+cargo test -p ruview-offaxis          # 23 unit tests + doctest
+cargo clippy -p ruview-offaxis --all-targets   # zero warnings
+cargo build -p ruview-offaxis --target wasm32-unknown-unknown --release
+```
