@@ -25,6 +25,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **`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.

+## 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.
+
+## Threat model summary
+
+| Threat | Primary control | Residual risk |
+|---|---|---|
+| Spoofed/replayed sensor | ADR-305 identity, MAC, sequence and replay window; correction gate | Compromised legitimate sensor |
+| Altered model/floor/config | Signed hashes, authenticated configuration, atomic activation | Authorized unsafe configuration |
+| Poisoned data/splits | Immutable manifests, strict split validator, witnessed benchmarks | Subtle label poisoning |
+| Operator repudiation | Append-only witnessed transition with actor/old/new hash/reason | Compromised signer |
+| Biometric/log leakage | Track-local retention and fixed metric allowlist | Aggregate inference |
+| Track/geometry CPU flood | Authentication, cardinality/geometry/allocation/deadline caps | Valid dense-scene overload |
+| Remote mode escalation | Capability-scoped local control plane, deny by default | Compromised operator capability |
+| Derived output relabeled observed | Required schema/provenance and signed event envelope | Malicious downstream stripping |
+
+The implementation review records commit, lockfile hash, Rust toolchain,
+scanner versions, and advisory-feed timestamp.
+
+## 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.
+- **G2 shadow correction**: strict-disjoint measured median MPJPE improvement
+  >=10% with positive 95% CI lower bound; foot slide >=30% and jerk >=25%
+  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.
+
+## Testing and completion evidence
+
+Unit/property/fuzz/integration/security coverage maps to requirements R1-R13:
+raw hash, confidence, modes, malformed/stale/frame/covariance input, caps and
+deadlines, provenance, dependency graph, pose diversity/fall preservation,
+strict splits, fail-to-raw faults, no network capability, and authenticated
+source/replay selection.
+
+Release commands include focused core/physics tests, default/dynamics/learned
+feature checks, format/clippy, benches, `cargo deny`, `cargo audit`, strict split
+verification, and golden replay verification. Completion also requires JSON
+schemas, measured Pi 5/x86 rows, strict manifest hashes, raw/refined metrics,
+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.

+# ADR 346: Fail closed ESP32 occupancy evidence
+
+## Status
+
+Accepted and implemented. Physical qualification is required after each firmware build.
+
+## Date
+
+2026 08 31
+
+## Context
+
+The ESP32 Tier 2 pipeline produces two different signals. Presence is a debounced room level decision. Person count is a bounded subcarrier diversity heuristic. A live four node installation emitted packets with `presence=false` and `n_persons=3` or `4`. The server eventually gated the aggregate room count, but raw WebSocket consumers and diagnostics could still treat the contradictory count as occupancy evidence.
+
+That contradiction is more dangerous than a missed optional count. It can contaminate empty room calibration, train a room model on false labels, and encourage a product claim that the firmware cannot support. The count is not identity, pose, or a validated multi person estimator.
+
+## Decision
+
+1. Firmware person slots are subordinate to the debounced presence gate.
+2. When presence is false, the firmware clears slot activity, slot history, candidate count, persistence streak, and stable count.
+3. The serialized person count is always zero when presence is false and is clamped to `EDGE_MAX_PERSONS` when presence is true.
+4. The sensing server repeats the invariant for older firmware. A contradictory or out of range count becomes zero and carries `person_count_valid=false`.
+5. Fused CSI plus mmWave packets use either CSI presence or mmWave presence as the supporting presence condition.
+6. The node inventory and WebSocket diagnostics expose person count validity. Consumers must not infer a person from an invalid count.
+7. No count accuracy claim is created by this change. The firmware output remains a heuristic until a leakage free, held out physical dataset demonstrates otherwise.
+8. OTA admission uses the selected update partition size rather than a stale fixed 900 KB ceiling. The status endpoint reports that same hardware bound, while image validation and authenticated OTA remain mandatory.
+
+## Security and privacy
+
+The change retains no raw CSI or personal data. It reduces authority by preventing a secondary heuristic from asserting occupancy after the primary gate has closed. The host validates packet length, magic, range, and logical consistency before using count evidence.
+
+## Consequences
+
+Older firmware remains wire compatible. Invalid count evidence becomes visibly unavailable instead of silently affecting calibration. A true multi person event can still be undercounted when the presence gate is false, which is the intended fail closed behavior. Current C6 images larger than 900 KB can use the installed 1,900,544 byte OTA slots after one serial upgrade, without weakening the OTA authentication gate.
+
+The largest uncertainty is whether the current presence gate itself generalizes across the installed rooms. The fix path is a room bound empty baseline plus the fixed room selective held out protocol, not a global threshold reduction.
+
+## Evidence and acceptance
+
+MEASURED before implementation on 2026 08 31: four live nodes streamed for 86 seconds with zero transport errors, while edge packets repeatedly contradicted `presence=false` with counts of three or four.
+
+Software acceptance requires:
+
+1. Host firmware tests prove absent plus four active slots serializes zero.
+2. Rust parser tests prove contradictory and out of range counts fail closed.
+3. The node API exposes count validity without breaking older firmware.
+
+Physical acceptance requires the updated firmware on a confirmed board, a captured boot log, five minutes of live packets, zero logical count contradictions, and no increase in transport errors. Accuracy remains unmeasured until labelled held out sequences are recorded.
+
+Physical occupancy qualification completed for ESP32 C6 node 4 on 2026 08 31. The five minute run observed 242 edge packets, including 61 absent packets, with zero logical count contradictions and zero parse errors. See `docs/validation/2026-08-31-esp32-c6-occupancy-integrity.md`.
+
+ESP32 C6 node 7 was subsequently identified, upgraded to firmware 0.8.8, and transport qualified for five minutes with zero fused presence count contradictions and zero steady state transport errors. Its controlled empty room sequence remains required before occupancy qualification. See `docs/validation/2026-08-31-esp32-c6-node7-rate-aware-sensing.md`. Other nodes remain unqualified until separately identified and upgraded.

+# ADR 347: Rate aware ESP32 temporal sensing
+
+## Status
+
+Accepted. Implemented in firmware 0.8.8. The timing and transport path is
+physically qualified on ESP32 C6. The independent raw transport path is also
+physically qualified on an ESP32 S3 running Tier 0. Held out inference accuracy
+remains required.
+
+## Context
+
+The ESP32 firmware creates CSI opportunities by sending one byte ICMP probes to
+the connected access point. The traffic source is configured for 50 Hz, but the
+delivered CSI cadence varies with channel contention and callback safety gates.
+A physical ESP32 C6 produced 28 to 37 callbacks per second during the baseline
+capture. Firmware 0.8.5 then exposed that the old per-interval estimator saw
+only 12 to 16 Hz because WiFi replies arrived in short bursts separated by
+longer gaps. The filters still consumed those burst frames, so excluding them
+from the clock estimate was incorrect.
+
+The edge DSP estimates its sample rate from timestamps so that breathing,
+heartbeat, motion, and future Doppler features stay in physical Hertz. That
+estimator was capped at 30 Hz. Once the actual cadence exceeded the cap, every
+temporal feature was scaled against the wrong clock.
+
+Physical firmware 0.8.5 validation corrected that initial diagnosis. Although
+the callback path received 26 to 40 frames per second, Tier 2 on the unicore C6
+processed an irregular subset that converged toward the 8 Hz estimator floor.
+The right design is not to force the edge DSP to match raw capture. The paths
+need independent, explicit cadence contracts.
+
+The device free gesture preprint at
+`https://www.preprints.org/manuscript/202602.0018` reinforces the importance of
+timestamp correct Doppler features, but its 100 Hz controlled link is not a
+safe firmware default for RuView. Existing S3 and C6 evidence records WiFi ISR
+and packet buffer failures under sustained callback pressure above 50 Hz.
+
+## Decision
+
+1. Make the connected STA probe rate a build time setting from 10 through 50
+   Hz, with a default and hard ceiling of 50 Hz.
+
+2. Track the delivered DSP cadence by counting every processed frame interval
+   over one second timestamp windows, then smooth successive windows in an 8
+   through 60 Hz estimator range. The 60 Hz estimator ceiling accommodates
+   timestamp jitter; it does not authorize more than 50 Hz callback processing.
+
+3. Reject incomplete windows below one second and stalled windows above three
+   seconds. Do not discard valid burst frames from the estimated clock.
+
+4. Surface the DSP rate in the one second controller diagnostic so hardware
+   validation can compare callback yield with the clock used by temporal
+   filters.
+
+5. Keep raw CSI on the wire at the independent network cadence. Rate-limit the
+   C6 on-device Tier 1 and Tier 2 DSP input to a uniform 8 Hz. Physical 0.8.7
+   evidence showed that a requested 10 Hz input still converged to 8.0 through
+   8.4 Hz under Tier 2 load, while raw delivery remained 30 through 40 pps.
+   Eight hertz retains a 4 Hz Nyquist limit for the 0.1 through 2.0 Hz vital
+   bands without creating a backlog. The S3 default remains 20 Hz.
+
+6. STFT, spectrogram gating, and learned temporal
+   classification remain host or iPhone responsibilities where memory,
+   rollback, and held out evaluation are stronger.
+
+## Consequences
+
+Heartbeat, respiration, and motion features receive a stable timestamped clock
+instead of an accidental subset determined by C6 backlog. Operators can lower
+the probe or DSP load for constrained networks without editing source. The host
+still receives the higher-rate raw stream for richer Doppler processing.
+
+This does not prove vital sign accuracy or gesture recognition. Higher temporal
+fidelity only improves the representation available to a separately validated
+model. The 50 Hz ceiling also means the paper's 100 Hz results are not directly
+transferable.
+
+## Acceptance test
+
+On a physical C6, run at least five minutes after flashing. Pass when the boot
+log reports the configured probe and DSP rates, the controller converges within
+one hertz of the configured DSP cadence, raw callback yield remains at least 20
+pps, no steady-state ENOMEM, watchdog, panic, or reboot occurs, and the fail
+closed occupancy invariant remains zero contradictions for at least 30 absent
+packets.

+# ADR-348: Independent Rust multivariate forecasting for RuView
+
+- **Status**: Proposed
+- **Date**: 2026-09-01
+- **Deciders**: ruv
+- **Owners**: RuView perception, model, security, and data-governance maintainers
+- **Tags**: forecasting, rust, ruvector, temporal, uncertainty, clean-room, provenance
+- **Extends**: ADR-016, ADR-020, ADR-145, ADR-273, ADR-282, ADR-295,

+- **Supersedes**: None
+
+## Executive decision
+
+RuView will develop an independently specified and independently trained Rust
+multivariate forecasting subsystem. It will forecast bounded, versioned
+temporal feature streams, publish calibrated quantiles and an explicit
+abstention state, optionally use a split-safe RuVector analogue index, and
+remain advisory until all release gates in this ADR pass.
+
+This is not a port, compatibility layer, distillation, or behavioural clone of
+Google TimesFM. The implementation API is derived from RuView requirements.
+Its weights must descend from an approved random initialization and approved
+training data only.
+
+**Evidence status at proposal:** the forecasting accuracy, false-alert
+reduction, calibration, CPU latency, memory use, cross-building generalization,
+and operational value described below are all **UNMEASURED targets**. This ADR
+authorizes implementation and evaluation; it makes no `MEASURED` capability
+claim and approves no production model.
+
+## Context
+
+RuView currently observes present and recent RF state. Forecasting could add a
+separate answer to questions such as whether a feature trajectory is consistent
+with real occupancy, whether motion is likely to transition between zones, or
+whether a radio link is degrading. A forecast is not a sensor observation. It
+is derived evidence with uncertainty and must never overwrite the immutable
+observation that produced it.
+
+TimesFM 3 is useful research context because its public description discusses
+multivariate targets, past covariates, known-future covariates, probabilistic
+outputs, temporal patching, and cross-series attention. Its licensing creates
+two distinct surfaces:
+
+- the Google TimesFM source repository states that source code is Apache-2.0;
+- the TimesFM 3 pretrained weights are distributed under a separate
+  non-commercial, non-production license that also restricts commercial
+  training, fine-tuning, and distillation from the model.
+
+An Apache-compliant Rust port would be a permissible but attributed derivative
+source path, subject to its exact license obligations. It would not support the
+strongest independent-development claim. Using the restricted TimesFM 3 model
+or its outputs to create a RuView commercial model is outside this ADR. The
+project therefore chooses the stricter clean-room protocol in
+[`../security/ruview-forecast-clean-room.md`](../security/ruview-forecast-clean-room.md).
+
+Clean-room controls reduce copyright, contract, and provenance risk. They do
+not establish freedom to operate against patents, clear trademarks, approve a
+dataset, or replace legal review in a launch jurisdiction.
+
+## Options considered
+
+1. **Use the TimesFM 3 checkpoint in RuView.** Rejected for commercial and
+   production use under the current checkpoint license.
+2. **Translate the Apache-licensed implementation into Rust.** Not selected.
+   This can be evaluated under a separate ADR, with attribution and license
+   compliance, but must not be mixed with the independent-development path.
+3. **Build an independent Rust forecasting specialist for RuView.** Chosen.
+   This narrows model scope, keeps inference native, controls provenance, and
+   makes RF-specific evaluation the source of authority.
+4. **Do not add forecasting.** Retained as the deployment baseline. Forecasting
+   must beat simpler deterministic and statistical baselines before acquiring
+   runtime authority.
+
+## Requirements
+
+| ID | Requirement | Verification authority |
+|---|---|---|
+| RF-001 | No TimesFM 3 code, configuration, weights, parameters, outputs, activations, or derivatives enter specification, implementation, training, evaluation feedback, or release artifacts. | Clean-room manifest, contributor attestations, repository and artifact scans |
+| RF-002 | Every contributor, reference, dependency, dataset, transform, training job, and checkpoint has immutable provenance. | Signed provenance manifests and review receipts |
+| RF-003 | Every training byte has documented rights for commercial machine-learning use and applicable privacy approval. | Dataset licensing gate and data-steward approval |
+| RF-004 | The default runtime is native Rust, bounded, offline, deterministic for a fixed artifact/input within the declared platform class, and free of runtime model download. | Unit, property, fuzz, replay, and dependency tests |
+| RF-005 | Inputs and outputs are versioned, finite, bounded, timestamped, mask-aware, and provenance-labelled. Invalid, stale, insufficient, or OOD inputs abstain. | Contract tests and malformed-input corpus |
+| RF-006 | Forecasts remain derived evidence. They cannot rewrite observations, silently increase observation confidence, or be relabelled `MEASURED`. | Schema invariants and evidence-engine tests |
+| RF-007 | Quantile ordering, interval calibration, missing-data behaviour, and abstention are evaluated on leakage-free site/session/device holdouts. | Frozen evaluation manifest and reproducible report |
+| RF-008 | RuVector retrieval is optional, split-scoped, provenance-recorded, and evaluated against the same model without retrieval. | Retrieval isolation tests and paired ablation |
+| RF-009 | RuVLLM may explain or summarize a signed forecast but cannot alter numeric forecasts, bypass policy, spend money, or trigger medical, emergency, access-control, or life-safety action. | Capability tests and downstream policy review |
+| RF-010 | Training on local Linux or a hosted accelerator uses identical signed code, container, data, and configuration identities; the provider is an untrusted processor. | Training receipts and digest comparison |
+| RF-011 | Accuracy, latency, memory, power, and operational claims remain `UNMEASURED` or `CLAIMED` until a named reproducer satisfies the repository evidence contract. | Documentation and release review |
+| RF-012 | Rollout is reversible and cannot advance from offline evaluation to shadow or advisory operation without the mapped gates below. | Signed mode transition and rollback drill |
+
+## Architecture boundary
+
+The initial implementation is split across three crates:
+
+| Crate | Owned responsibility | Dependency/runtime rule |
+|---|---|---|
+| `ruview-forecast-core` | Backend-neutral schemas, invariants, metrics, forecast receipts, and the `Forecaster` trait | No Burn, CUDA, WGPU, provider SDK, sensing-server, or network dependency |
+| `ruview-forecast-model` | Independent Burn 0.21 patch-mixer architecture and artifact execution | CPU, CUDA, and WGPU are explicit optional features; every backend feature is off by default |
+| `ruview-forecast-train` | Dataset manifests/splits, trainer, evaluator, the `ruforecast` CLI, and Linux/fal.ai training assets | Training-only authority; no production activation or sensing-server mutation |
+
+This PR does not connect the forecaster to the sensing server. A shadow bridge
+requires a follow-up change after the core contract and evidence receipt have
+stabilized. Landing crates or passing synthetic tests therefore creates no
+live RuView forecasting capability.
+
+Version one activates only the exact reviewed `tiny_ci` and `large_linux`
+architecture profiles. The model and training boundaries enforce checked
+dimension, parameter, activation-cell, input-cell, and forward multiply-add
+limits per batch. Adding or changing a profile is therefore a reviewed code and
+artifact-schema decision, not untrusted request configuration.
+
+The proposed logical pipeline is:
+
+```text
+authenticated RF observations
+        |
+        v
+versioned one-second feature windows
+        |
+        +----> split-scoped RuVector analogue retrieval (optional)
+        |
+        v
+independent Rust temporal model
+        |
+        v
+point forecast + ordered quantiles + validity mask + abstention
+        |
+        v
+signed derived-evidence record
+        |
+        +----> RuView policy/evidence engine
+        +----> RuVLLM explanation with no numeric mutation authority
+```
+
+The initial feature contract should favour compact one-second summaries rather
+than feeding an unbounded raw CSI stream. Candidate fields include motion
+energy, Doppler summary, amplitude/phase dispersion, coherence, RSSI, packet
+loss, channel utilization, current detector confidence, device temperature,
+and source-validity masks. Each field needs a schema version, physical unit,
+aggregation rule, validity semantics, and provenance. Adding a field is a
+schema change, not an implicit positional extension.
+
+The model may independently combine normalization, temporal patch encoding,
+temporal mixing, cross-stream fusion, and quantile heads. This is a functional
+design space, not permission to reproduce protected source expression,
+checkpoint dimensions, constants, tests, diagrams, or API choices. Exact
+architecture and parameter count remain implementation decisions recorded in
+the model card and training receipt.
+
+## Forecast contract
+
+For each request the runtime returns one typed result, including abstention and
+error paths. The result must identify:
+
+- input schema, feature-window, model, configuration, and calibration digests;
+- source time range, requested horizon, cadence, target streams, and masks;
+- point estimate and declared quantiles for each target/horizon cell;
+- whether quantiles were corrected for crossing and which method was used;
+- OOD, insufficient-context, stale-input, and non-finite dispositions;
+- optional RuVector index version, neighbour identifiers, distances, and
+  leakage-scope receipt;
+- runtime platform class, duration, and peak-memory measurement when enabled;
+- evidence label `DERIVED_FORECAST`, never `MEASURED_OBSERVATION`;
+- deterministic content hash and optional RVF signature.
+
+The runtime rejects non-finite values, duplicate or non-monotonic timestamps,
+unsupported schema versions, unbounded dimensions, invalid quantile requests,
+future covariates without an allowed source, and payloads above configured
+limits. It abstains rather than imputing an authoritative state when history or
+validity coverage is below the model-card threshold.
+
+## RuVector integration
+
+RuVector supplies temporal memory, not ground truth. During training and
+evaluation, each split has a separate index built only from records permitted
+for that split. A test query may retrieve training analogues, but it may never
+retrieve a window from the same subject/session/site holdout, an overlapping
+target horizon, or any test record. Fitted normalizers and retrieval thresholds
+come from training data only.
+
+Every release reports three comparable rows on identical examples:
+
+1. deterministic/statistical baseline;
+2. forecasting model without retrieval;
+3. forecasting model with RuVector retrieval.
+
+This prevents retrieval from hiding a weak model or leaking future state.
+
+## RuVLLM and action authority
+
+RuVLLM consumes an immutable, signed forecast record and may produce an
+explanation referencing its uncertainty and provenance. Its prose is not the
+forecast and receives no higher evidence grade. Numeric values exposed to APIs
+come from the forecasting record, not regenerated text.
+
+No forecast or LLM explanation independently triggers a health alert, emergency
+response, access decision, actuator, firmware change, model promotion, or
+commercial spend. Such actions require a separate governed policy, explicit
+capability, and appropriate observed evidence.
+
+## Training and artifact boundary
+
+Training jobs run from a pinned container or reproducible local environment.
+The receipt binds the source commit, lockfile, compiler, container, datasets,
+transforms, architecture, hyperparameters, seeds, hardware, provider job ID,
+start/end time, and every emitted checkpoint. Hosted workers receive only the
+least data and credentials necessary. Provider caches, logs, retention, and
+reuse rights must pass security and data review before customer-derived data is
+uploaded.
+
+A release artifact is immutable and hash addressed. It is loaded locally after
+signature, schema, size, and compatibility verification. The inference process
+does not fetch models, execute embedded code, accept arbitrary operators, or
+contact the training provider.
+
+## Leakage and evaluation protocol
+
+- Split by deployment/site first, then subject, session, device, and contiguous
+  time block as applicable. No overlapping raw sequence or derived window may
+  cross a split.
+- Freeze test manifests before tuning. A failed test result does not become a
+  new training target; material architecture changes require a new untouched
+  holdout.
+- Fit normalization, calibration, feature selection, thresholds, and RuVector
+  index parameters on training/validation data only.
+- Report missingness, abstention coverage, selective risk, per-horizon errors,
+  interval coverage, quantile loss, and results by site/device/interference
+  regime. Pooled performance cannot hide a failed domain.
+- Compare against last value, seasonal naive, and at least one small classical
+  or recurrent baseline. TimesFM 3 output is not an acceptance oracle.
+- Forecast evaluation does not prove presence, pose, fall, respiration, or
+  medical accuracy. Any downstream claim requires its own labelled protocol.

+
+Failure at any gate keeps the model offline or shadow-only. Passing a software
+gate is not real-hardware evidence and does not convert an accuracy target into
+a measurement.
+
+## Rollout and rollback
+
+The only permitted progression is:
+
+```text
+OFF -> OFFLINE_EVAL -> SHADOW -> ADVISORY
+```
+
+This ADR does not authorize autonomous action. Each transition records actor,
+old/new mode, artifact and configuration digests, evidence report, and reason.
+Regression, provenance failure, calibration drift, security incident, or
+licensing uncertainty returns immediately to `OFF` or `SHADOW` while observed
+RuView sensing continues unchanged.
+
+Rollback deactivates the forecast artifact atomically, clears ephemeral model
+and retrieval state, preserves signed aggregate evidence and incident records,
+and never downgrades or rewrites the raw observation stream.
+
+## Security and privacy
+
+Forecasting can infer routines from occupancy and movement even without raw
+CSI. Feature windows, neighbour identifiers, forecasts, and explanations are
+therefore deployment data subject to purpose limitation, tenant isolation,
+retention, deletion, access control, and audit.
+
+Model artifacts, feature schemas, calibration, indexes, and manifests are
+untrusted until their signature and digest verify. Cardinality, dimensions,
+horizon, context, allocations, execution time, and concurrent requests are
+bounded. Metrics use allowlisted aggregate values and exclude raw CSI, precise
+room coordinates, persistent person identifiers, and unrestricted feature
+payloads.
+
+The detailed authoring, data, AI-tool, incident, trademark, and patent controls
+are normative in
+[`../security/ruview-forecast-clean-room.md`](../security/ruview-forecast-clean-room.md).
+
+## Consequences
+
+### Positive
+
+- RuView gains a provider-neutral predictive evidence primitive with explicit
+  uncertainty and abstention.
+- Rust-native inference can be evaluated on CPU without requiring a Python or
+  cloud runtime in production.
+- RuVector retrieval becomes a measurable ablation rather than an implicit
+  memory claim.
+- Signed provenance supports reproducible Linux and hosted training.
+
+### Negative
+
+- Independent training needs substantial diverse, correctly licensed temporal
+  data and untouched deployment holdouts.
+- Strict source separation and manifests increase contributor and review cost.
+- A plausible forecast can make weak sensing look more authoritative unless
+  downstream evidence labels remain intact.
+- Clean-room development does not remove patent, trademark, privacy, or dataset
+  risk.
+
+### Neutral
+
+- This ADR does not repair an inaccurate upstream presence or pose estimator.
+- It does not approve TimesFM 3 for RuView use.
+- It does not select a final model size, training budget, or hosted provider.
+- No production checkpoint or measured benchmark is created by this decision.

+## Decision
+
+RuView Forecast will use one Rust training engine behind two deliberately
+different request boundaries. The local Linux request may bind a governed,
+hash-addressed RuView JSONL shard. Hosted v1 accepts only a bounded,
+deterministic synthetic generator recipe. It cannot serialize a local
+`TrainSpec`, `DataPolicy`, path, dataset bytes, tenant/account/workspace/site/
+device/session identity, split receipt, or RuVector namespace.
+
+The fal.ai path is a bounded execution adapter, not a remote shell. It may
+train the fixed synthetic profile and export fixed artifact kinds, but it may
+not choose an arbitrary command, executable, container, URL, environment
+variable, output path, or release action. A later real-data hosted path needs a
+new accepted ADR, provider/privacy review, and an operator-signed export grant;
+it is intentionally not implemented here.
+
+Every hosted result is untrusted and quarantined until it is exported with a
+complete receipt, downloaded through the authenticated provider channel,
+re-hashed locally, scanned, and bound to the original request. Only the local
+release boundary may sign or activate it. Signing keys never enter fal.ai.
+
+This ADR delegates dataset rights, clean-room evidence, model-card, patent,
+trademark, and production gates to [ADR-348](./ADR-348-independent-rust-multivariate-forecasting.md)
+and the [clean-room protocol](../security/ruview-forecast-clean-room.md).
+
+**Evidence status:** typed local and hosted configuration, root-confined file
+verification, atomic fixed-kind artifact publication, and cooperative
+cancellation source surfaces exist. End-to-end local training and mock hosted
+transport are software-testable in this change. Real fal.ai execution,
+provider cancellation, cost reconciliation, quarantine promotion, and local
+signature verification remain **UNMEASURED and unapproved** until their named
+acceptance evidence exists.
+
+## Context
+
+The same training engine needs to run on a 128 GiB Linux workstation and on an
+optional hosted accelerator without creating two architecture lineages. A
+generic remote-command interface would allow request data to become executable
+authority, make cost difficult to bound, and weaken cancellation. Sending a
+general local request to fal would also expose governance and customer
+identifiers that the hosted smoke path does not need.
+
+The initial `ruview-forecast-train` crate already separates three relevant
+modules:
+
+| Module | Current contract |
+|---|---|
+| [`config.rs`](../../v2/crates/ruview-forecast-train/src/config.rs) | `TrainingRequest`, `ValidatedTrainingRequest`, bounded `JobId`, root-relative dataset path, exact size/SHA-256, named model profiles, typed CPU/CUDA choice, and bounded optimizer values; unknown fields are denied |
+| [`artifact.rs`](../../v2/crates/ruview-forecast-train/src/artifact.rs) | verified open dataset handle, root confinement, fixed `Model`/`Manifest`/`Receipt`/`Checkpoint` kinds, atomic writes, content descriptors, and conflict-on-different-bytes idempotency |
+| [`cancel.rs`](../../v2/crates/ruview-forecast-train/src/cancel.rs) | `Cancellation`, `CancelToken`, and cooperative cancellation checks for batch/checkpoint boundaries |
+
+The training crate features keep `cli`, `server`, `fal-client`, `cpu`, and
+`cuda` explicit, with default features empty. WGPU remains a model-crate
+inference backend and is not advertised as a training runner. The `ruforecast`
+binary requires the `cli` feature. Source presence is not execution evidence.
+
+## Typed execution contracts
+
+The non-serializable trusted `TrainingRequest` is built locally from a
+size-bounded `LocalTrainingRequestWire`. It contains:
+
+- stable job identity;
+- a constructor-validated local split/horizon/normalization `TrainSpec`;
+- either a root-relative dataset identity with exact byte count and SHA-256,
+  or a deterministic synthetic recipe;
+- one allowlisted model capacity profile and compiled-in local backend;
+- bounded optimizer, checkpoint cadence, seed, memory, step, time, checkpoint,
+  and artifact budgets.
+
+Local JSON and TOML deny unknown fields. Dataset paths resolve below an
+operator-configured root, and the exact regular file remains open after
+size/hash verification to avoid replacement between validation and use. JSONL
+windows are decoded incrementally with per-line and per-window caps rather
+than loading the full shard into memory.
+
+The distinct `HostedSyntheticRequestV1` contains only a schema version,
+idempotency/request digests, a fixed model profile, deterministic generator
+parameters and seed, bounded optimizer/resource caps, and public build
+identities. Its constructor needs a non-serializable core governance authority
+proving that the synthetic recipe is the approved hosted source. Hosted v1 has
+no external dataset field.
+
+Neither request contains a shell string, argument vector, executable path,
+container/image selector, package installer, arbitrary URL, callback URL,
+environment map, secret, source fragment, or unrestricted output name.
+
+The local client maps `HostedSyntheticRequestV1` to one allowlisted,
+process-configured fal app and pre-deployed content-addressed worker image. The
+caller cannot override the app, machine, worker entry point, or artifact
+destination. The endpoint returns typed status or artifact descriptors only.
+Provider paths are derived from validated job identity and fixed artifact
+kinds, then downloaded through the authenticated fal Platform Files API; they
+are not accepted as remote URLs or local paths.
+
+The deploy wrapper builds from an allowlisted `git archive`, selects the exact
+`fal_app.py::run_server` symbol, and passes `--auth private` for both `fal run`
+and `fal deploy`; ephemeral Fal runs otherwise default to public. Hosted v1
+retains only bounded synthetic request/result metadata so its typed queue result
+can be reconciled. It sets `X-Fal-No-Retry: 1` and a bounded timeout rather than
+claiming that `X-Fal-Store-IO: 0` or an unverified lifecycle header protects
+the result. A live unauthenticated 401/403 probe and provider retention/deletion
+reconciliation remain blocking operational evidence.
+
+## Idempotency and cost authority
+
+The local effective idempotency identity is:
+
+```text
+job_id + canonical request digest + source commit + lockfile digest
++ container digest + dataset/split digest + initial-weight digest
+```
+
+Hosted v1 replaces `dataset/split digest` with the canonical synthetic-recipe
+digest. No local governance identifier is part of, or derivable from, the
+hosted payload.
+
+Repeating an identical completed request returns the existing verified receipt
+and descriptors. Reusing `job_id` with any different governed input fails as a
+conflict. A retry after an ambiguous network failure must first query the same
+provider job; it must not silently create a second billable run.
+
+Before hosted submission, the caller sets explicit maximum steps, wall-clock
+time, memory, checkpoint count, export bytes, and billable units. Submission
+also requires an explicit local spend-approval record bound to the request
+digest and maximum units. The adapter rejects a request when its configured
+cap exceeds that approval. The final receipt records estimated and actual
+provider units/cost when the provider supplies them, the price source/time,
+and whether the amount is final or provider-reported. A provider estimate is
+`CLAIMED`, never `MEASURED`, until reconciled against a bill.
+
+No automatic retry may increase the approved budget. Budget changes create a
+new signed authorization record. The initial wire carries operator ceilings
+for wall time, billable seconds, and micro-USD, but it does not yet bind a
+provider price quote or reconcile a final provider ledger. Monetary enforcement
+therefore remains an operator/Fal-account control and the production hosted
+spend gate stays open.
+
+## Cancellation and checkpoints
+
+Cancellation is cooperative and idempotent:
+
+1. Local signal or authenticated hosted cancel marks one `job_id` cancelled.
+2. Training checks `Cancellation` at every batch boundary and before/after each
+   checkpoint/export boundary.
+3. A cancellation checkpoint is committed atomically when safe and within the
+   artifact budget; a partial file never becomes a valid artifact.
+4. The terminal receipt records `cancelled`, the last completed epoch/step,
+   checkpoint digest, provider state, elapsed resource units, and final known
+   cost.
+5. Repeating cancel returns the same terminal state.
+
+Cancellation does not promise immediate GPU termination. Cancellation latency,
+checkpoint durability, and residual provider billing are **UNMEASURED** until a
+real fal.ai run supplies a receipt. A timeout or lost cancellation response
+keeps the job and any output quarantined.
+
+## Export, quarantine, and local signing
+
+The worker may emit only the fixed artifact set from `ArtifactKind`:
+
+| Kind | Required purpose |
+|---|---|
+| `Model` | Burn model record bytes |
+| `Manifest` | architecture, data/split, seed, build, and clean-room identity |
+| `Receipt` | request, environment, metrics, cost, status, and export lineage |
+| `Checkpoint` | final or cancellation-time model weights; v1 does not claim optimizer/cursor resume |
+
+Every descriptor includes kind, size, and SHA-256. Export acceptance requires
+all mandatory descriptors, bounded lengths, exact hashes, the expected job and
+request digest, no duplicate kind, and a terminal status consistent with the
+artifact set.
+
+Downloaded files enter a non-executable quarantine outside the model search
+path. Local verification repeats envelope/schema/size/hash checks, SBOM and
+malware/policy scans, clean-room declarations, dataset/split lineage, metric
+labels, and parent-checkpoint validation. No provider output may update a
+symlink, current-model pointer, RuVector index, sensing server, or release tag.
+
+After quarantine passes, an authorized local signer binds the exact export
+receipt and artifact digests to an `ArtifactReceipt` and release manifest. The
+signature records algorithm, public key ID, signer capability, and time. Fal.ai
+receives no private signing material and cannot promote its own output. The
+current core supplies canonical digests and receipts, not a complete release
+signature implementation; signature-backed activation remains open.
+
+## Requirements and acceptance
+
+| ID | Requirement | ADR-348 gate | Acceptance evidence | Current state |
+|---|---|---|---|---|
+| FT-001 | Local and hosted adapters invoke the same model/trainer implementation while using intentionally separate local-data and hosted-synthetic request schemas. | G1 | Shared-engine tests plus hosted DTO exclusion and recipe-digest binding tests | **OPEN / UNMEASURED** |
+| FT-002 | No request field or endpoint can select arbitrary code, command, image, URL, environment, or output path. | G2 | Schema negatives, endpoint capability test, dependency review | **OPEN / UNMEASURED** |
+| FT-003 | Job/request idempotency prevents duplicate execution and conflicts on changed governed input. | G1, G5 | Concurrent/retry/lost-response tests with provider job query | **OPEN / UNMEASURED** |
+| FT-004 | Hosted execution has explicit non-escalating resource and monetary caps with estimated/actual cost receipts. | G5 | Over-budget rejection and reconciled provider-bill fixture plus real-run receipt | **OPEN / UNMEASURED** |
+| FT-005 | Cancellation is authenticated, cooperative, idempotent, checkpoint-safe, and terminally receipted. | G2, G5 | Local property tests and a real hosted cancellation drill | **OPEN / UNMEASURED** |
+| FT-006 | Export is fixed-kind, bounded, complete, hash-verified, and bound to request/job/environment. | G1, G2 | Missing/duplicate/truncated/tampered export tests | **OPEN / UNMEASURED** |
+| FT-007 | Hosted outputs remain quarantined until local verification and local-only signing succeed. | G1, G5 | Promotion-denial tests, signing-key absence check, rollback drill | **OPEN / UNMEASURED** |
+| FT-008 | Hosted v1 receives synthetic inputs only; provider credentials, logs, retention, region, output reuse, and deletion satisfy ADR-348 privacy/security approval before any real run. | G1, G5 | Hosted DTO exclusion tests, provider review, and deletion/export receipts | **OPEN / UNMEASURED** |
+
+No successful unit test closes a hosted gate. G5 requires one bounded real
+fal.ai run, one cancellation drill, one ambiguous-retry/idempotency drill, cost
+reconciliation, quarantine rejection of a tampered export, and local signature
+verification over the accepted artifact. Until then fal.ai support is a typed
+software surface, not an operational capability claim.
+
+## Consequences
+
+The design gives local and hosted training one auditable lineage and keeps
+provider output below local release authority. It adds receipt, budget,
+quarantine, and signing work, and cooperative cancellation may still incur
+provider cost. If a hosted provider cannot support bounded idempotent status,
+export, cancellation, and deletion, the Linux path remains the only approved
+training environment.

+# ADR-350: RuVector predictive memory and RuVLLM authority boundary
+
+- **Status**: Proposed
+- **Date**: 2026-09-01
+- **Deciders**: ruv

+- **Tags**: forecasting, ruvector, ruvllm, retrieval, memory, receipts, authority

+
+## Decision
+
+RuVector may augment RuView Forecast by retrieving analogous historical
+feature/forecast states from a tenant- and split-scoped predictive-memory
+index. Retrieval is optional context, never ground truth. Every release must
+report the same frozen examples with retrieval disabled and enabled so its
+incremental value and leakage risk remain visible.
+
+Each forecast is published in an immutable, locally signed envelope binding the
+model artifact, request, output, source evidence, and retrieval receipt. RuVLLM
+may read that envelope to explain uncertainty and analogous history. It may not
+rewrite numeric forecasts, create a stronger evidence class, select a model,
+promote an artifact, spend money, invoke an actuator, or make medical,
+emergency, access-control, or life-safety decisions.
+
+This child ADR delegates forecasting, clean-room, data, and general production
+gates to [ADR-348](./ADR-348-independent-rust-multivariate-forecasting.md). It
+does not authorize a sensing-server bridge.
+
+**Evidence status:** canonical forecast/receipt types and an indexable latent
+state exist in source. A RuVector adapter, retrieval receipt, signature wrapper,
+outcome reconciler, RuVLLM explanation adapter, paired retrieval evaluation,
+latency, storage cost, accuracy lift, and operational value are all
+**UNMEASURED and unapproved**.
+
+## Existing implementation boundary
+
+The current crates establish only the preconditions:
+
+| Module | Implemented surface used by this ADR |
+|---|---|
+| [`ruview-forecast-core/src/forecast.rs`](../../v2/crates/ruview-forecast-core/src/forecast.rs) | validated `ForecastRequest`, backend-neutral `Forecaster`, ordered finite `Forecast`, canonical output digest, and receipt verification |
+| [`ruview-forecast-core/src/receipt.rs`](../../v2/crates/ruview-forecast-core/src/receipt.rs) | `SourceState`, `ArtifactReceipt`, and `ForecastReceipt`; derived forecasts cannot retain `MEASURED` merely because measured input existed |
+| [`ruview-forecast-core/src/series.rs`](../../v2/crates/ruview-forecast-core/src/series.rs) | bounded feature schema, masked time series, canonical series digest, and training-only scaler fit |
+| [`ruview-forecast-model/src/network.rs`](../../v2/crates/ruview-forecast-model/src/network.rs) | `ForecastModelOutput.state` with shape `[batch, variates, d_model]`, intended as a bounded representation candidate for indexing |
+
+`ForecastReceipt` is content-addressed but not itself a digital signature.
+`ForecastModelOutput.state` is indexable but not automatically safe, private,
+stable across model versions, or useful. Those distinctions remain release
+gates.
+
+## Predictive-memory record
+
+RuVector stores a versioned `PredictiveMemoryRecord` containing:
+
+- tenant and index namespace;
+- model/artifact/config/feature-schema digests;
+- source series and forecast-request digests;
+- split, site, subject-class, session, device, calibration, and bounded time
+  scope using pseudonymous identifiers;
+- bounded latent-state or engineered-feature digest plus the approved vector;
+- forecast envelope digest and horizon;
+- observed validity mask and evidence class;
+- optional reconciled outcome digest added only after the forecast horizon;
+- retention/deletion class and creation/expiry time.
+
+Raw CSI, unrestricted feature windows, precise room coordinates, persistent
+person identity, RuVLLM prompts, and explanation prose are excluded by default.
+The vector is still potentially sensitive because it can encode routines or
+location. Tenant isolation, encryption, access control, retention, deletion,
+and membership-inference review apply.
+
+An outcome is appended through a new immutable record linked to the original;
+the historical forecast is never rewritten. Outcome reconciliation can measure
+forecast quality but cannot retroactively turn the forecast into a measured
+observation.
+
+## Split-scoped analogue retrieval
+
+Every index is bound to an immutable corpus manifest, model version, feature
+schema, preprocessing configuration, and split policy. These rules are
+mandatory:
+
+1. Tenants never share an index or query result without a separately authorized
+   privacy-preserving federation protocol.
+2. Training, validation, calibration, and test records have distinct
+   namespaces. A test query may retrieve approved training analogues only; it
+   may not retrieve test examples or validation/calibration records used to set
+   thresholds.
+3. The same site, subject, session, device, calibration episode, overlapping
+   context, or overlapping target horizon is excluded when that dimension is a
+   holdout.
+4. Index construction, distance metric, normalization, filter policy, `k`, and
+   score threshold are fitted on training data and frozen before test.
+5. Missing, stale, mismatched, unauthorized, or unverifiable indexes disable
+   retrieval and return the no-retrieval forecast or abstention according to
+   the model card. They never trigger an implicit global-index fallback.
+6. Every query returns a bounded `RetrievalReceipt` even when zero neighbours
+   qualify.
+
+The retrieval receipt binds query digest, index/corpus/policy digests,
+namespace, exclusion filter, neighbour record IDs and distances, `k`, latency,
+and disposition. It excludes raw neighbour payloads from ordinary logs.
+
+## Paired ablation
+
+Retrieval has no deployment authority without a paired evaluation on identical
+frozen requests:
+
+| Row | Model and examples | Retrieval |
+|---|---|---|
+| A | exact candidate artifact and frozen examples | disabled |
+| B | exact candidate artifact and frozen examples | enabled with frozen index/policy |
+
+The report includes weighted quantile loss, interval coverage/width,
+abstention, per-horizon error, per-site/device/interference slices, retrieval
+hit/filtered/empty rates, latency, and memory/storage overhead. It reports both
+aggregate and paired deltas with uncertainty. A gain on pooled error cannot
+hide a failed deployment domain, calibration regression, or neighbour leakage.
+
+The no-retrieval row remains a supported fallback. Retrieval is removed when
+its lower confidence bound does not show useful improvement, when it weakens
+calibration beyond the ADR-348 gate, or when its privacy/latency/storage cost
+exceeds its measured value. No uplift is claimed today.
+
+## Immutable signed forecast envelope
+
+The signed envelope covers:
+
+```text
+envelope schema/version
++ ArtifactReceipt canonical digest
++ ForecastRequest canonical digest
++ Forecast payload/output digest
++ ForecastReceipt canonical digest
++ RetrievalReceipt digest or explicit retrieval-disabled marker
++ policy/calibration/index digests
++ creation/expiry time and tenant namespace
+```
+
+Signing occurs at the trusted local boundary after artifact and retrieval
+verification. The wrapper records algorithm, public key ID, signer capability,
+and signature. Private keys never enter model artifacts, RuVector, RuVLLM, or a
+hosted training worker.
+
+Consumers verify signature, expiry, tenant, schemas, every nested digest, and
+the `Forecast::verify_receipt` invariant before using numeric values. Any
+failure yields unavailable/abstain. Unsigned content-addressed receipts remain
+useful for local tests but are not described as signed and cannot cross the
+production trust boundary.
+
+## RuVLLM explanation boundary
+
+RuVLLM receives a read-only projection of the verified envelope:
+
+- exact point and quantile values as structured fields;
+- units, horizons, calibration/OOD/abstention state;
+- bounded analogue summaries and retrieval receipt references;
+- evidence labels, model/version, and envelope digest;
+- approved explanation policy and audience.
+
+Explanation prose is stored separately and linked to the envelope digest. It
+is `CLAIMED_EXPLANATION`, not a replacement forecast. Numeric API fields are
+copied from the verified envelope after generation, never parsed back from LLM
+text. If prose contradicts a structured number, evidence state, unit, or
+disposition, the response fails validation and the numeric envelope remains
+authoritative.
+
+The explanation capability exposes no tools for artifact activation, model
+promotion, retraining, spending, messaging, emergency dispatch, access control,
+or actuation. A separate downstream policy may consume a forecast only under
+its own ADR, capabilities, approvals, and observed-evidence requirements. The
+LLM cannot grant itself that authority or lower an approval threshold.

+G3 additionally requires the paired retrieval ablation to satisfy ADR-348's
+forecast and calibration gates. G4 requires shadow evidence that retrieval and
+explanation improve operator comprehension or forecast value without changing

+
+## Consequences
+
+RuVector can evolve from retrospective search into outcome-linked predictive
+memory while preserving a measurable no-retrieval baseline. RuVLLM can make
+forecasts understandable without becoming the numeric or action authority. The
+cost is additional index isolation, storage, signature, deletion, evaluation,
+and policy complexity. If paired evidence does not justify that cost, the
+correct release keeps retrieval and explanation disabled.

+No measured accuracy evidence has been recorded. The deterministic tests are
+L0/SYNTHETIC contract evidence only and cannot satisfy G2.
+
+## Validation and supply-chain record
+
+- The default dependency graph is checked to exclude Burn, Rapier, Tch, and
+  ONNX Runtime. Dynamics and learned backends remain opt-in.
+- 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.
+- The standalone fuzz lock SHA-256 is
+  `d386c4edb130bb6b2d1a4ef77334c78e25e0695e90a9d97c01284876acb8c2c6`.

+# RuForecast benchmark protocol
+
+## Evidence status
+
+No RuForecast runtime, accuracy, calibration, memory, or operational result is
+recorded here yet. Every threshold below is an ADR-348 target, not a measured
+claim. The first accepted row must identify a clean commit, the `Cargo.lock`
+digest, the exact Rust toolchain, host, backend, model/configuration digest,
+fixture or corpus digest, command, and evidence label.
+
+## Benchmark boundaries
+
+RuForecast uses two different forms of evidence:
+
+1. Deterministic correctness evidence comes from Rust unit, property, replay,
+   split-isolation, and artifact-tamper tests. A fixed input and artifact must
+   produce the same output within its declared platform class.
+2. Runtime evidence comes from Criterion on a named host. Criterion inputs are
+   generated from fixed checked-in code and seeds, but elapsed time is not
+   deterministic. Timing from shared GitHub runners is informational only.
+
+The benchmark implementation must not download a model or dataset, read raw
+CSI, use a hosted model output, or enable CUDA implicitly. CPU benchmarks use
+the explicit `cpu` feature and the Burn ndarray backend. CUDA validation belongs
+to a separately governed Linux or hosted-accelerator receipt.
+
+## Required benchmark targets
+
+| Package | Target | Purpose | CI authority |
+|---|---|---|---|
+| `ruview-forecast-model` | `forecast_inference` | Fixed-seed forward pass, batch and shape scaling, ordered-quantile output | Compile gate; shared-runner timing is informational |
+| `ruview-forecast-train` | `data_pipeline` | Fixed generated records through validation, windowing, masking and batching | Compile gate; shared-runner timing is informational |
+
+Both targets must use code-generated synthetic inputs, fixed seeds, bounded
+allocations, `criterion::black_box`, and `required-features = ["cpu"]`. Setup,
+artifact construction, and dataset generation stay outside the timed region
+unless a benchmark name explicitly says they are included.
+
+The model implementation owns structural parameter-count assertions. The
+currently reviewed design values are 35,700 parameters for the tiny CI preset
+and 20,285,108 for the large preset. These are design invariants, not benchmark
+results, and must be derived by a test from the actual module graph before they
+are quoted in a model card.
+
+## Local Linux reproducer
+
+Run from a clean checkout after installing Rust 1.92.0:
+
+```bash
+RUFORECAST_CPUSET=0-7 \
+RUFORECAST_THREADS=8 \
+scripts/run-ruforecast-benchmarks.sh
+```
+
+The runner executes the focused contract/model/training tests, one real
+optimizer step over a local hash-addressed synthetic JSONL shard, and the
+idempotent synthetic CLI smoke. It then compile-checks both Criterion targets,
+runs the targets, captures the CPU and toolchain metadata, and hashes every
+output. A failed run retains its partial logs with `status=FAILED` and its exit
+code rather than looking like a complete report. Results go under
+`target/ruforecast-evidence/`, which is excluded from source control.
+
+For a conservative single-thread reproducibility check, omit both environment
+variables. To run against an uncommitted tree for diagnosis only, set
+`RUFORECAST_ALLOW_DIRTY=1`; the resulting metadata is labelled `SYNTHETIC`
+with scope `DIRTY_WORKTREE_DIAGNOSTIC_ONLY` and cannot support a release claim.
+
+A clean run labels its host timing `MEASURED` and its input class `SYNTHETIC`,
+but remains `UNREVIEWED`. Only a maintainer may append it to the accepted ledger
+after checking the digests, shape, command, Criterion report and host scope.
+
+The runner intentionally has no CUDA option and does not parse Criterion output
+into a pass/fail performance verdict. This prevents a noisy host result from
+silently acquiring release authority.
+
+To compile the two benchmark targets without measuring them:
+
+```bash
+cd v2
+cargo +1.92.0 bench --locked -p ruview-forecast-model \
+  --no-default-features --features cpu --bench forecast_inference --no-run
+cargo +1.92.0 bench --locked -p ruview-forecast-train \
+  --no-default-features --features cpu --bench data_pipeline --no-run
+```
+
+For a short informational run, use the same targets without `--no-run`:
+
+```bash
+cargo +1.92.0 bench --locked -p ruview-forecast-model \
+  --no-default-features --features cpu --bench forecast_inference -- \
+  --warm-up-time 1 --measurement-time 2 --sample-size 10
+cargo +1.92.0 bench --locked -p ruview-forecast-train \
+  --no-default-features --features cpu --bench data_pipeline -- \
+  --warm-up-time 1 --measurement-time 2 --sample-size 10
+```
+
+Running these commands does not add a ledger row automatically. Preserve the
+raw report and environment metadata, then have a maintainer assign its evidence
+scope before publishing a number.
+
+The inference bench runs only `tiny_ci` by default so a routine CI trend step
+cannot accidentally start the very expensive large CPU probe. Set
+`RUFORECAST_BENCH_LARGE=1` only on a controlled host when intentionally
+measuring the fixed deployment shape:
+
+```bash
+RUFORECAST_BENCH_LARGE=1 scripts/run-ruforecast-benchmarks.sh
+```
+
+## Deployment measurement shape
+
+The initial CPU deployment probe is batch 1, context 1,024, 32 declared feature
+streams, the fixed `large_linux` horizon of 300, and all seven declared
+quantiles. Record at least 20 warmup
+iterations and 200 measured iterations for a release candidate. Report p50,
+p95, p99 or maximum, throughput, and the process peak resident set size.
+
+ADR-348 G5 currently targets p95 at or below one second for 32 declared streams
+and peak process memory at or below 4 GiB. A Criterion result alone cannot close
+the memory gate because Criterion and Cargo are not the production inference
+process. G5 remains open until a standalone inference probe reports its own peak
+resident set size.
+
+## Accuracy and calibration protocol
+
+Runtime speed never substitutes for forecasting quality. The frozen evaluation
+manifest must report identical examples for:
+
+1. Last-value and seasonal-naive baselines.
+2. RuForecast without RuVector retrieval.
+3. RuForecast with split-scoped RuVector retrieval.
+
+Required report fields include weighted quantile loss by horizon, nominal 80%
+interval coverage, missingness, abstention coverage, selective risk, site and
+device slices, interference regime, and retrieval ablation. ADR-348 G3 targets
+weighted quantile loss at least 10% better than seasonal naive and 80% interval
+coverage between 75% and 85%. Those targets remain unmeasured until a frozen,
+leakage-free report is attached.
+
+### Informal HPO exploration note (unaccepted, not a release claim)
+
+**2026-09-01.** An exploratory session ran the accuracy protocol above end to
+end against a governed 24-window **synthetic** dataset (`tiny_ci` profile,
+context 64 / horizon 12, temporal train/test split, not entity-holdout —
+only one synthetic generator was used, so entity holdout does not apply) and
+a small `OptimizerSpec` hyperparameter search (learning rate, weight decay,
+gradient clip norm, batch size, epochs) using a new Darwin Mode numeric-genome
+evolution engine (upstream: `ruvnet/metaharness` PR #260, not yet merged).
+This is **exploratory evidence only** — not a frozen, leakage-free,
+maintainer-reviewed report, and not eligible for the ledger below until one
+is produced.
+
+Prior to this exploration, a **single real household window** (76 real
+1 Hz vital-signs samples, one physical ESP32 sensor, temporal not entity
+holdout) scored **worse than both baselines** (WQL 0.537 vs. last-value
+0.106 and seasonal-naive 0.123) — consistent with a single training window
+overfitting rather than generalizing.
+
+With a larger (still synthetic, still `tiny_ci`) 24-window training set and
+three rounds of hyperparameter search, weighted quantile loss on the held-out
+synthetic split improved and stayed ahead of both baselines throughout:
+
+| Round | learning_rate | weight_decay | grad_clip | batch | epochs | WQL (model) | WQL (last-value) | WQL (seasonal-naive) |
+|---|---:|---:|---:|---:|---:|---:|---:|---:|
+| Default config | 0.0010000 | 1.00e-4 | 1.000 | 8 | 60 | 0.257 | 0.277 | 0.514 |
+| Search round 1 | 0.0002356 | 3.05e-6 | 0.100 | 27 | 195 | 0.161 | 0.277 | 0.514 |
+| Search round 2 | 0.0000298 | 4.09e-11 | 4.746 | 26 | 356 | **0.153** | 0.277 | 0.514 |
+
+Round-2 gain over round 1 (−0.008) was much smaller than round-1's gain over
+the default (−0.096) — a diminishing-returns signal consistent with a local
+optimum for this model size and dataset, not a converged global result.
+`gradient_clip_norm` landed at opposite bound extremes across rounds
+(0.1 then 4.7), so no directional recommendation on that parameter should be
+drawn from this exploration alone.
+
+**Explicit scope limits — do not generalize beyond these:**
+- `tiny_ci` only. Nothing here has been run against `large_linux`; its far
+  larger parameter count and different compute profile mean these
+  hyperparameters are not a starting point for it without their own search.
+- Synthetic dataset only (24 windows, one generator/seed family). Not
+  validated against any real corpus at this scale.
+- Self-signed, evaluation-only model activation (a throwaway local Ed25519
+  key, not a release signature) was used to run inference for scoring.
+- No security/provenance/maintainer-approval gate has passed — the Darwin
+  Mode promotion rule correctly refused to promote any candidate here.
+
+Reproducer: `harness/ruview/flywheel/ruforecast/` (genome, gate, evaluator,
+dry-run/`--confirm` driver) in the `ruvnet/RuView` repo, paired with
+`ruvnet/metaharness` PR #260 (`evolve-numeric`) linked locally via
+`npm link`. Neither the genome defaults here nor any repo default config
+were changed by this note — it is a record of exploratory evidence, not a
+committed recommendation.
+
+### Amendment (2026-09-01, later same day): the round-2 result above did not generalize -- retracted
+
+**The "Search round 2" row above (WQL 0.153, learning_rate=0.0000298 etc.) is
+RETRACTED as a claim of improvement.** It is kept in the table (append-only,
+never silently edit a prior measurement) but must be read together with this
+amendment: independent verification, run the same day using a new
+regression-candidate promotion path (`ruvnet/autogenous` PR-in-progress,
+branch `feat/regression-candidate-kind`, not yet merged/pushed --
+`v2/crates/ruforecast-autogenous-bridge` in this worktree) against TWO FRESH
+synthetic corpora that were never part of that search (seeds 1000/1097, vs.
+the search's single fixed seed 0), showed that "winner" genome performing
+**WORSE than the baseline on both**:
+
+| Judge corpus | Candidate WQL | Baseline WQL | Candidate beats baseline by |
+|---|---:|---:|---:|
+| seed 1000 | 0.155 | **0.099** | -0.056 (worse) |
+| seed 1097 | 0.219 | **0.109** | -0.110 (worse) |
+
+**Root cause**: every evaluation in the three search rounds above (default,
+round 1, round 2) trained and scored every candidate against the exact same
+fixed synthetic corpus (`prepare-synthetic-dataset`'s implicit `--seed 0`
+default). The search had learned to exploit that one corpus's specific
+random windows -- textbook overfitting -- not found a genuinely better
+hyperparameter configuration. This is a real, measured failure mode, not a
+hypothetical caveat.
+
+**Fix applied**: `harness/ruview/flywheel/ruforecast/gate.mjs`'s
+`evaluateGenome` now trains and scores every candidate against THREE
+independent synthetic corpora (`DEFAULT_SEARCH_SEEDS = [11, 23, 47]`, none
+of which overlap the retracted search's seed 0 or the verification seeds
+1000/1097) and takes the WORST CASE `primary` across them, not an average --
+a candidate only counts as a win if it beats both baselines on every corpus.
+See `harness/ruview/flywheel/ruforecast/README.md`'s "Multi-seed fitness"
+section for the full account.
+
+**Re-running the search with the fix, still no verified improvement.** A
+fresh search under the corrected multi-seed fitness (2 generations x 2
+children, cleared `.metaharness-numeric` archive so no stale pre-fix state
+leaked in) found a genuine winner ON ITS OWN THREE SEARCH SEEDS --
+`learning_rate=0.008012, weight_decay=0.000159, gradient_clip_norm=0.267,
+batch_size=24, epochs=20`, beating the baseline on all three (primary
+0.099 / 0.556 / 0.576, worst-case 0.099). Independent verification against
+the same fresh seeds 1000/1097 (never part of this candidate's own search)
+again showed it losing to the baseline on both:
+
+| Judge corpus | Candidate WQL | Baseline WQL | Candidate beats baseline by |
+|---|---:|---:|---:|
+| seed 1000 | 0.178 | **0.099** | -0.079 (worse) |
+| seed 1097 | 0.314 | **0.109** | -0.205 (worse) |
+
+**Honest conclusion**: two independent search rounds (pre- and post- the
+multi-seed fitness fix) both produced a genome that looked like a real
+improvement on its own search data and both failed independent out-of-sample
+verification. This converges on a different, deeper explanation than "the
+search methodology was broken" (that part IS fixed): at this dataset scale
+(24 synthetic training windows), held-out WQL varies enormously by which
+corpus is drawn REGARDLESS of hyperparameters -- the baseline genome itself,
+evaluated with the corrected multi-seed fitness function, swings from
+primary 0.83 (a strong win) to a full regression (primary 0, WQL worse than
+last-value) purely from which of the three fixed search seeds was used, with
+identical hyperparameters throughout. The corpus-noise floor at n=24
+windows appears to dominate any real hyperparameter effect. No RuForecast
+hyperparameter configuration has been shown, by this exploration, to
+reliably beat the trivial baselines out-of-sample at this scale. A larger
+training corpus (more windows, ideally real governed data under the
+`large_linux` profile) is the more promising next lever than further
+hyperparameter search on this fixture.
+
+A related implementation-only fix: the promotion verifier
+(`envelope::regression::verify_regression_promotion` in the Autogenous
+branch above) initially required all judges' receipts to share one
+`corpus_id`, inherited unreviewed from a same-evidence review model that
+does not fit this kind's intentionally cross-corpus judge design. This was
+corrected (`ReceiptCorpusMismatch` is no longer produced by that function);
+it did not change either REJECT verdict above, both of which were already
+correctly driven by the real `NotBetterThanParent` signal.
+
+Reproducer for both verification runs above: same as below, plus
+`v2/crates/ruforecast-autogenous-bridge` (`cargo +1.92.0 run --manifest-path

+### Real-household-data result (2026-09-01, MEASURED, unaccepted, not a release claim)
+
+Following the informal HPO exploration above, this session also collected
+**6,390 real 1&nbsp;Hz vital-signs samples** (heart rate, breathing rate,
+signal quality) from a real, live, ESP32-sourced household sensing
+deployment over a continuous 2-hour window (88.75% real sample coverage;
+gaps handled honestly via `observed_mask=0`, never fabricated
+interpolation) — the "more real training data" lever flagged as the
+credible next step in the note above. This directly answers that open
+question.
+
+Two genuinely independent temporal splits of the same real corpus (not
+synthetic seeds — real data has no seed to vary, so independence here
+means two different train/test boundary choices on the same timeline,
+each with its own 90s embargo gap) were trained (default, untuned
+`OptimizerSpec`: `lr=0.001, weight_decay=0.0001, gradient_clip_norm=1.0,
+batch_size=8, epochs=60`) and scored via the real `evaluate` CLI, then
+independently, cryptographically verified through
+`ruforecast-autogenous-bridge`'s real signed regression-candidate
+promotion path (`ruvnet/autogenous`, `envelope::regression`):
+
+| Judge | Split | Real test windows | Model WQL | Best trivial baseline WQL | Model beats baseline by |
+|---|---|---:|---:|---:|---:|
+| 1 | 70% train / 90s embargo / 30% test | 27 | 0.0514 | 0.0563 (last-value) | +0.0049 |
+| 2 | 50% train / 90s embargo / 50% test | 46 | 0.0670 | 0.0543 (seasonal-naive) | −0.0128 |
+
+**Signed verdict: REJECT.** Judge 1's nominal win (+0.0049) is below the
+0.01 non-inferiority margin, so it doesn't clear the promotion bar even
+on its own; Judge 2 lost outright. Both rejections are recorded as
+`NotBetterThanParent` in the signed promotion envelope.
+
+**Honest conclusion:** even with a real household corpus (n=6,390 real
+samples, not synthetic), the result is exactly the same shape as every
+synthetic search this session — a result that looks like a win on one
+split does not hold up on an independently verified second split. This
+is not evidence that real data can't help; it is evidence that this
+scale of real data (6,390 samples, one household, one physical sensor)
+is not yet enough to distinguish a genuine effect from split-dependent
+noise. The credible next lever remains more real data — more households,
+longer collection windows, or the `large_linux` profile — not further
+hyperparameter search on any fixture this small, synthetic or real.

+### Real public dataset: BIDMC PPG/Respiration (2026-09-02, cross-entity holdout)
+
+Every real-data test up to this point used a single household/entity with only
+a **temporal** holdout (same physical sensor, different time windows). This
+test is the first with a genuine **cross-entity** holdout: 53 real ICU
+patients from the BIDMC PPG and Respiration Dataset (PhysioNet, Open Data
+Commons Attribution License v1.0, public and openly licensed — no
+credentialing, https://physionet.org/content/bidmc/1.0.0/), splitting by
+*patient*, not by time, so the held-out test set contains real people the
+model never saw during training.
+
+25,546 real 1 Hz rows across 53 recordings (~8 minutes each), heart rate +
+respiratory rate + SpO2. 3 of 53 patients' windows were excluded honestly
+(genuine sensor-dropout `NaN` values in the source recordings, not
+fabricated/interpolated). Two independent, disjoint patient-partition splits:
+
+| Judge | Train patients | Test patients | Test windows | Model WQL | Best baseline WQL | Result |
+|---|---:|---:|---:|---:|---:|---|
+| A (contiguous split) | 34 | 16 | 16 | 0.01964 | 0.01159 (last-value) | worse, +69% |
+| B (interleaved split) | 24 | 26 | 26 | 0.07022 | 0.01002 (last-value) | worse, +601% |
+
+**Same conclusion as every prior test this session**, now on real, public,
+multi-subject clinical data with genuine cross-entity generalization: the
+model does not beat trivial forecasting baselines. The margin is decisive on
+both independent splits, not a near-miss — the earlier hypothesis that a
+larger, genuinely diverse real dataset (many different people, not one
+household) might change the picture does not hold at this scale/model
+configuration either.
+
+**Honest scope note on verification**: prior real-data tests in this document
+were independently checked through Autogenous's signed regression-candidate
+promotion path. That additional cryptographic-signing step was **not** run
+for this test — the result is reported directly from the `evaluate` CLI's
+real output on two genuinely disjoint, real patient-holdout splits, which is
+itself real, independent, out-of-sample evidence, but it does not carry a
+signed promotion-gate verdict the way the earlier entries do. Flagging this
+explicitly rather than presenting it with the same evidentiary weight.

+2. Label every numeric claim `MEASURED`, `SYNTHETIC`, `CLAIMED`, or
+   `UNMEASURED` under the repository evidence policy.
+3. A `MEASURED` value needs an immutable dataset/split, artifact digest,

+4. Use `UNMEASURED` when evidence does not exist. Do not substitute an estimate.
+5. State source-code, weight, dataset, and service terms separately.

+# RuView ESP32 firmware 0.8.8
+
+Firmware 0.8.8 is a reliability and correctness release for ESP32-S3 and
+ESP32-C6 RuView nodes. It makes the timing used by signal processing explicit,
+prevents contradictory occupancy output, and improves update diagnostics.
+
+## What changed
+
+### Empty means zero people
+
+Older firmware could report `presence=false` and a nonzero person count in the
+same edge packet. That was internally contradictory and could contaminate an
+empty-room calibration. Firmware 0.8.8 clears the count whenever the presence
+gate is closed. The sensing server repeats the same check when it receives data
+from older nodes.
+
+This is a consistency fix, not proof that the heuristic can count multiple
+people accurately. See
+[ADR 346](../adr/ADR-346-fail-closed-edge-occupancy-evidence.md).
+
+### Stable time scale on ESP32-C6
+
+Raw CSI and on-device signal processing now have separate clocks. The C6 keeps
+raw CSI moving over the network while its Tier 2 filters process a stable 8 Hz
+sample stream. The S3 retains its 20 Hz DSP default. A phase-preserving sampler
+keeps callback jitter from shifting those clocks.
+
+The result is a correct time base for motion and vital-band features. It does
+not by itself prove that heartbeat, respiration, gesture, or pose estimates are
+more accurate. See
+[ADR 347](../adr/ADR-347-rate-aware-esp32-temporal-sensing.md).
+
+### Better diagnostics and safer updates
+
+The one-second controller log now shows both raw callback yield and DSP rate.
+The OTA status endpoint reports the actual selected application partition size
+instead of a fixed 900 KB assumption. Firmware upload remains fail closed when
+the node has no provisioned OTA signing secret.
+
+## Measured hardware validation
+
+All results below are physical measurements from 2026-08-31. They are not
+simulator claims.
+
+| Board | Duration | Raw CSI mean | DSP clock | Live coverage | Steady-state transport errors |
+|-------|---------:|-------------:|----------:|--------------:|------------------------------:|
+| ESP32-C6 node 4 | 300.64 s | 34.92 pps | 8.00 Hz | 97.62% | 0 |
+| ESP32-C6 node 7 | 300.70 s | 36.32 pps | 8.00 Hz | 97.40% | 0 |
+| ESP32-S3 node 1 | 300 s | 28.03 pps | Tier 0 | 100.00% | 0 |
+
+The first C6 empty-room qualification observed 61 absent packets with zero
+nonzero counts. The second C6 was transport-qualified in an occupied room and
+still needs its own controlled empty-room sequence. Full evidence is recorded
+in:
+
+1. [C6 timing and transport](../validation/2026-08-31-esp32-c6-rate-aware-sensing.md)
+2. [C6 occupancy integrity](../validation/2026-08-31-esp32-c6-occupancy-integrity.md)
+3. [Second C6 timing and transport](../validation/2026-08-31-esp32-c6-node7-rate-aware-sensing.md)
+4. [S3 transport](../validation/2026-08-31-esp32-s3-rate-aware-transport.md)
+
+## Choose the correct download
+
+| Release file | Target |
+|--------------|--------|
+| `esp32-csi-node-v0.8.8-s3-8mb-flash-bundle.zip` | ESP32-S3 with 8 MB flash |
+| `esp32-csi-node-v0.8.8-s3-4mb-flash-bundle.zip` | ESP32-S3 with 4 MB flash |
+| `esp32-csi-node-v0.8.8-c6-4mb-flash-bundle.zip` | ESP32-C6 using the supported 4 MB partition layout |
+| `esp32-csi-node-v0.8.8-s3-8mb.bin` | S3 8 MB application only |
+| `esp32-csi-node-v0.8.8-s3-4mb.bin` | S3 4 MB application only |
+| `esp32-csi-node-v0.8.8-c6-4mb.bin` | C6 application only |
+
+Never mix S3 and C6 images. Confirm the chip and physical flash before writing.
+
+## Install or update
+
+For a fresh installation, extract the matching bundle and follow its included
+`FLASHING.md`. The standard offsets are:
+
+| Image | Offset |
+|-------|-------:|
+| Bootloader | `0x0000` |
+| Partition table | `0x8000` |
+| OTA metadata | `0xf000` |
+| Application | `0x20000` |
+
+For an existing provisioned node:
+
+1. Back up the current application partition.
+2. Confirm the exact chip, flash layout, logical node, and serial port.
+3. Read `http://DEVICE_IP:8032/ota/status`.
+4. Use an application-only serial update at `0x20000` only when the running
+   partition is `ota_0` and the image matches the board.
+5. Reboot and confirm version 0.8.8, the preserved node identity, channel, and
+   sensing-server target.
+6. Run a five-minute burn-in before returning the node to calibration duty.
+
+The full bundle does not contain an NVS image. A four-offset install therefore
+preserves the existing WiFi and node settings, but operators should still keep
+a backup before changing firmware.
+
+## What this release does not prove
+
+Firmware 0.8.8 does not prove medical-grade vital signs, accurate person
+counting, identity, dense pose, through-wall video, or room separation. Those
+claims require synchronized references and leakage-free held-out sequences.
+
+The practical next acceptance test is a controlled empty-room capture with at
+least 30 absent edge packets per updated node, zero absent packets carrying a
+nonzero count, and zero transport or parser errors. Accuracy evaluation then
+needs held-out occupied, movement, heartbeat-reference, and adjacent-room
+sequences.

+# RuView Forecast clean-room, data, and release protocol
+
+**Status:** Proposed and mandatory for any artifact claiming independent
+development under ADR-348.
+
+**Evidence status:** This document defines controls. It does not assert that the
+controls have passed, that a trained model exists, or that any forecasting
+capability is measured. Every ADR-348 gate remains **OPEN / UNMEASURED** until a
+signed evidence bundle proves otherwise.
+
+## 1. Purpose and authority
+
+This protocol governs the specification, implementation, training, evaluation,
+hosting, and release of the independent Rust multivariate forecaster defined by
+[ADR-348](../adr/ADR-348-independent-rust-multivariate-forecasting.md).
+It applies to source, issue and review text, prompts, dependencies, datasets,
+intermediate tensors, checkpoints, containers, CI caches, RuVector indexes,
+fal.ai jobs, benchmark results, model cards, and published artifacts.
+
+The protocol is intentionally stricter than the minimum conditions for using
+Apache-licensed source. Its purpose is to preserve evidence that the RuView
+implementation and weights were independently created. It is not a legal
+opinion. The legal release owner must approve the current licenses, contributor
+exposure record, patent review, trademark review, datasets, and intended launch
+jurisdictions before production.
+
+## 2. License boundary as of 2026-09-01
+
+The authoritative public materials state two different license surfaces:
+
+1. The [Google TimesFM repository](https://github.com/google-research/timesfm)
+   identifies its source code as Apache-2.0.
+2. The [TimesFM 3 checkpoint license](https://huggingface.co/google/timesfm-3.0-pytorch/blob/main/LICENSE)
+   permits non-commercial, non-production use and restricts commercial use,
+   distribution, and use to train, fine-tune, or distill another commercial
+   model.
+
+The checkpoint license defines a derivative broadly enough that relying on its
+logic, parameters, or model-generated material creates avoidable contractual
+risk. No contributor may accept gated model terms on behalf of the project or
+its owner without written authorization.
+
+The [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0) permits
+source reproduction and derivative works subject to its conditions, including
+license delivery, change notices, retention of applicable notices, and NOTICE
+handling. Apache also provides a limited contributor patent grant and no general
+trademark grant. If maintainers ever choose an Apache-derived port, it must use
+a separate branch, attribution path, artifact name, and superseding ADR. It
+must not be described as the clean-room implementation.
+
+Publicly described ideas, procedures, processes, systems, and methods are not
+the same as copied expression. United States copyright law states the
+idea-expression boundary in [17 U.S.C. section 102(b)](https://www.copyright.gov/title17/92chap1.html).
+That does not settle contract, patent, trademark, database-right, trade-secret,
+or non-U.S. law questions.
+
+## 3. Non-mixing rule
+
+Only one of these paths may govern a source tree:
+
+| Path | Source basis | Required representation |
+|---|---|---|
+| Independent implementation | Approved abstract specification, public papers/articles, general literature, RuView requirements, approved data | "Independently developed and independently trained" after all gates pass |
+| Apache-derived port | Apache-licensed Google source with full license and notice compliance | "Apache-derived Rust port" with attribution |
+
+There is no hybrid path. A permissive source license makes porting possible; it
+does not make a port independent. If exposure cannot be bounded, maintainers
+must either quarantine and rewrite the affected component or reclassify the
+whole affected component under the Apache-derived path.
+
+## 4. Roles and separation
+
+| Role | May access | Must not access or do |
+|---|---|---|
+| Clean-room custodian | Exposure records, allowlist, scan reports, quarantined evidence | Contribute core model implementation after reviewing prohibited source fragments |
+| Specification reviewer | Frozen public-paper/article allowlist, RuView requirements, generic literature | Google TimesFM implementation, tests, configs, checkpoint files, model outputs; contribute implementation |
+| Rust implementer | Approved independent specification, RuView schemas, approved generic dependencies | TimesFM source, tests, configs, weights, outputs, line-by-line/API translation, reference differential testing |
+| Data steward | Dataset source, contracts, consent, privacy and transformation records | Approve unknown or incompatible rights; infer that a software license covers data |
+| Training operator | Signed code/container/config and approved dataset manifests | Change code/data/config outside a new receipt; add an unapproved parent checkpoint |
+| Independent evaluator | Frozen candidate, frozen evaluation manifests, approved baselines | Return reference predictions or implementation hints to developers; tune against the test set |
+| Legal release owner | Complete evidence bundle and private legal analysis | Treat clean-room checks as patent clearance or dataset approval by implication |
+
+One person may hold multiple roles only where the forbidden-access rules remain
+true. The strongest separation uses different people for public specification
+and implementation. A specification reviewer who has inspected prohibited
+source cannot become a core implementer for the independent path.
+
+## 5. Source classification
+
+### 5.1 Allowed
+
+- The public TimesFM research articles and peer-reviewed papers, frozen by URL,
+  retrieval date, and SHA-256 digest.
+- General time-series, transformer, probabilistic forecasting, normalization,
+  missing-data, and calibration literature.
+- RuView requirements, independently written feature schemas, and existing
+  RuView contracts whose provenance already satisfies repository policy.
+- Generic Rust dependencies whose license, source, and purpose are recorded and
+  approved.
+- Public benchmark specifications and datasets after the dataset gate passes.
+- Published aggregate competitor results used only as contextual background.
+
+### 5.2 Conditional
+
+- Code implementing generic algorithms may be used only after license review
+  and must be declared as a dependency or attributed source. It cannot be used
+  to claim that every line was independently authored.
+- TimesFM versions up to 2.5 may have permissively licensed code or weights, but
+  they remain outside the independent implementation and training path. An
+  evaluator may use an approved permissive baseline only after the candidate
+  is frozen, and its output cannot become training data or implementation
+  feedback.
+- A contributor with prior exposure to TimesFM code must disclose the exact
+  material and date. The custodian and legal owner decide whether the person is
+  limited to non-implementation work or the affected component must be
+  reclassified.
+- Synthetic data is allowed only when source data, generator code/model,
+  provider terms, output rights, and intended commercial use all pass review.
+
+### 5.3 Prohibited
+
+- TimesFM 3 weights, parameters, checkpoints, tensor dumps, checkpoint
+  configuration, hidden activations, embeddings, gradients, or derived
+  fingerprints.
+- TimesFM 3 forecasts, quantiles, scores, probabilities, recommendations, or
+  synthetic labels in development, training, tuning, or release evidence.
+- Fine-tuning, distillation, imitation, teacher-student learning, differential
+  testing, behavioural cloning, or hyperparameter search against TimesFM 3.
+- Manual, mechanical, or AI-assisted translation of Google source, tests,
+  comments, constants, APIs, file layout, or diagrams.
+- Third-party code, datasets, or checkpoints whose origin may contain copied or
+  distilled TimesFM material without documented permission.
+- Model, dataset, or service terms labelled non-commercial, research-only,
+  evaluation-only, no-derivatives, no-ML, no-production, or unknown.
+- Confidential third-party information or material obtained under an agreement
+  that does not authorize this implementation and commercial use.
+
+## 6. Exposure intake and contributor attestation
+
+Before receiving implementation access, every contributor completes an
+exposure intake covering:
+
+- TimesFM repositories, model cards, gated checkpoint files, local caches,
+  notebooks, issues, tutorials, and generated outputs viewed or downloaded;
+- whether gated terms were accepted and for which individual or entity;
+- source or output material placed in an LLM, IDE assistant, retrieval index,
+  prompt, or code-generation session;
+- prior work for Google, a competitor, customer, or other party involving
+  confidential forecasting implementation;
+- datasets, pretrained models, and external code expected in the contribution.
+
+Each pull request also carries a signed attestation:
+
+```text
+RuView Forecast clean-room attestation v1
+
+Contributor:
+Employer or represented entity:
+Role:
+Covered commits:
+Prior TimesFM exposure: NONE or complete disclosure
+Approved sources used:
+Datasets introduced:
+AI tools used:
+Prompt/session manifest digest:
+
+I attest that the covered contribution was created from the approved
+specification and listed sources. I did not access, copy, translate, decompile,
+query, distill, or use TimesFM 3 implementation material, configuration,
+weights, parameters, outputs, or internal representations. I did not place
+prohibited material in an AI tool context. I disclosed all contrary facts
+above. Every dependency and dataset I introduced has documented rights for its
+stated use.
+
+Signature:
+Timestamp:
+```
+
+A DCO `Signed-off-by` line does not replace this attestation. The attestation
+digest, not private identity material, is referenced from the public release
+manifest.
+
+## 7. Specification controls
+
+The custodian freezes an allowlist before implementation begins. Every entry
+records title, canonical URL or DOI, publication date, retrieval time, content
+digest, license or access terms, reviewer, and the abstract requirement it
+supports.
+
+The specification may state mathematical functions, tensor roles, input/output
+invariants, resource bounds, and RuView-specific requirements. It must not
+include copied source, comments, tests, distinctive identifiers, constants,
+checkpoint dimensions extracted from files, API compatibility requirements, or
+Google diagrams. RuView API names must be derived from the local domain.
+
+Changes to the specification after test evaluation receive a new version and
+must not encode held-out answers. A material architecture revision consumes a
+new untouched holdout or remains labelled exploratory.
+
+## 8. AI coding-tool controls
+
+An AI assistant can unintentionally defeat source separation by retrieving or
+reproducing reference code. For sessions contributing implementation:
+
+1. Disable web retrieval and repository indexing outside the approved local
+   tree where the tool supports it.
+2. If a user describes the goal as a port, clone, reproduction, or emulation,
+   stop and restate the task as independently authored RuView functional
+   requirements. Record that wording in the exposure manifest; do not use it
+   as permission to retrieve reference implementation material or pursue
+   behavioral equivalence.
+3. Do not attach Google code, checkpoint metadata, outputs, screenshots, or
+   detailed third-party implementation summaries.
+4. State the independent specification and prohibited-source boundary in the
+   session instructions.
+5. Retain a bounded prompt and tool-source manifest digest without committing
+   raw private transcripts.
+6. Record the model/tool version and whether retrieval was enabled.
+7. Treat unexplained code that resembles a prohibited implementation as an
+   incident, not as a harmless generated suggestion.
+
+AI-generated code receives the same authorship, license, security, and
+similarity review as human-authored code.
+
+## 9. Dataset licensing and privacy gate
+
+No dataset enters preprocessing, a RuVector index, training, calibration, or
+evaluation until a data steward records affirmative answers to every applicable
+gate:
+
+| Gate | Required evidence | Automatic rejection examples |
+|---|---|---|
+| Origin | Named owner/provider, acquisition method, immutable source digest | Scrape or file of unknown origin |
+| Training rights | Written right to use for ML training and the intended commercial purpose | Research-only, NC, no-ML, evaluation-only |
+| Derivatives | Right to transform, derive windows/features, and create model artifacts | No-derivatives or ambiguous custom terms |
+| Redistribution | Whether raw, transformed, manifests, and weights may be redistributed separately | Assumption that public access means redistribution |
+| Attribution | Exact attribution and notice obligations | Missing author/source/version |
+| Database rights | Jurisdiction and database-right review where applicable | Unreviewed EU database extraction |
+| Consent and contract | Collection authority, participant/customer consent, purpose, controller/processor roles | Customer telemetry without explicit model-training authority |
+| Sensitive inference | Classification of occupancy, routines, location, health-adjacent and biometric implications | Unbounded identity or health inference |
+| Minimization | Required fields only, pseudonymization, retention and deletion schedule | Raw CSI/person identifiers retained without need |
+| Split integrity | Site/subject/session/device/time-block lineage and overlap report | Contiguous or derived-window leakage across splits |
+| Synthetic lineage | Generator, seed data, service terms, output rights, seeds/config digest | Restricted teacher or prohibited source data |
+
+Typical disposition guidance:
+
+- Owned data, CC0/public-domain data, and data under an explicit commercial ML
+  contract may pass after privacy and provenance review.
+- CC BY data requires attribution plus database and downstream-weight review.
+- MIT and Apache are software licenses and do not automatically license nearby
+  data.
+- NC, ND, research-only, evaluation-only, no-ML, no-production, and unknown
+  terms fail unless a separate written commercial grant is obtained.
+
+Every transform is content-addressed. Normalizers, feature selectors,
+calibrators, thresholds, and RuVector indexes fit training data only. Raw
+sequence overlap and derived-window overlap are both checked. A parent record
+in one split makes all overlapping descendants ineligible for another split.
+
+## 10. Hosted training boundary
+
+The Linux machine and fal.ai are execution environments, not sources of
+authority. A hosted job is accepted only when:
+
+- the exact source commit, Cargo lockfile, compiler, container digest, data
+  manifests, configuration, seeds, and parent checkpoint digest are signed
+  before upload;
+- provider terms, retention, region, subprocessors, logs, cache deletion,
+  confidentiality, output ownership, and provider-training reuse have been
+  reviewed for the data classification;
+- credentials are short-lived, least-privilege, excluded from images and logs,
+  and rotated after suspected exposure;
+- customer-derived data is not uploaded before controller/processor and
+  transfer requirements pass;
+- emitted checkpoints and logs are hashed immediately and compared with the job
+  receipt;
+- the downloaded artifact is scanned before entering the trusted release
+  boundary;
+- a hosted provider cannot promote, sign, or activate a model.
+
+Hosted and local runs are comparable only when their governed input identities
+match. Numerical nondeterminism must be documented; it does not permit an
+unrecorded dependency, data, or configuration change.
+

+
+Secrets, raw personal identifiers, contract text, raw customer data, and
+private contributor identities stay outside the public manifest. The manifest
+references controlled records by digest or approval ID.
+
+## 12. Source, dependency, and artifact checks
+
+The custodian records tool versions, rules, timestamps, and complete findings.
+At minimum:
+
+- search the working tree and Git history for prohibited model IDs, URLs,
+  filenames, license strings, binary signatures, and unexpected large files;
+- scan source similarity against the prohibited implementation in an isolated
+  custodian environment; implementation contributors do not receive reference
+  fragments from the report;
+- manually adjudicate every material similarity match and record independent
+  origin, generic necessity, rewrite, or reclassification;
+- run dependency license, source, duplicate-version, and vulnerability policy
+  checks and generate a CycloneDX or SPDX SBOM;
+- inspect container layers, CI and provider caches, mounted volumes, model/data
+  buckets, notebooks, logs, and local tool indexes for restricted artifacts;
+- verify that every checkpoint parent is an approved RuView artifact or the
+  declared random initialization;
+- verify that model loading performs no network access and accepts no embedded
+  executable operator or arbitrary path;
+- verify that public packages, endpoints, docs, and metadata do not use Google
+  trademarks as a product identity.
+
+Keyword scans are a tripwire, not proof of independence. References in this
+governance document are expected and must be path allowlisted. The final result
+depends on provenance, exposure records, review, and the absence of prohibited
+material in implementation/training paths.
+
+## 13. Model card and claim gate
+
+Every candidate copies and completes
+[`../huggingface/RUVIEW_FORECAST_MODEL_CARD_TEMPLATE.md`](../huggingface/RUVIEW_FORECAST_MODEL_CARD_TEMPLATE.md).
+No placeholder, `UNMEASURED`, unknown license, missing digest, or missing
+approval may be silently deleted. It must instead be resolved or retained as an
+explicit release blocker.
+
+All accuracy, latency, memory, power, cost, and generalization values are
+labelled `MEASURED`, `SYNTHETIC`, `CLAIMED`, or `UNMEASURED` under repository
+policy. `MEASURED` requires a reproducer, immutable inputs, exact artifact, and
+named hardware/environment. A model-card benchmark does not create authority
+for a medical, emergency, security, or autonomous-action claim.
+
+## 14. Naming, trademark, and comparative statements
+
+Approved project identities include `RuView Forecast` and crate names derived
+from the RuView domain. Do not use `TimesFM`, `Google`, or a confusingly similar
+mark in crate names, binaries, model slugs, endpoints, logos, icons, or product
+headlines. Do not copy diagrams or visual branding.
+
+Comparative documentation may accurately identify an external model and its
+version when necessary, with a statement that RuView Forecast is independently
+developed and not affiliated with or endorsed by Google. Comparative claims
+need identical datasets, metric definitions, permitted model use, and evidence
+labels.
+
+Before public naming or commercial release, complete a professional trademark
+clearance that includes federal, state, common-law, domain, and relevant
+international sources. The [USPTO clearance guidance](https://www.uspto.gov/trademarks/search/comprehensive-clearance-search-similar-trademarks)
+is a starting point, not a complete legal opinion.
+
+## 15. Residual patent and jurisdiction risk
+
+Clean-room evidence does not prevent patent infringement. Before production,
+patent counsel performs a claim-level freedom-to-operate review covering at
+least temporal patching, multivariate/variate attention or mixing, masked
+horizon prediction, known-future covariates, probabilistic heads, normalization,
+retrieval augmentation, and relevant training procedures. Searches include
+assignees, inventors, continuations, unpublished timing uncertainty, and launch
+jurisdictions. The [USPTO Patent Public Search](https://www.uspto.gov/patents/search/patent-public-search)
+supports preliminary searching but is not a freedom-to-operate opinion.
+
+The Apache patent grant applies only within its stated scope. An independent
+implementation must not assume it inherits that grant. Public papers may be
+prior art yet still coexist with earlier, pending, territorial, or narrower
+claims.
+
+## 16. Contamination incident response
+
+Treat any prohibited source, output, model, data, or unreviewed exposure as a
+provenance incident:
+
+1. Stop affected implementation, training, evaluation feedback, and release.
+2. Preserve hashes, timestamps, actors, locations, access records, and affected
+   lineage. Do not erase the audit trail.
+3. Quarantine the material and revoke it from build, data, model, cache, and
+   retrieval paths.
+4. Identify every affected commit, specification revision, dataset transform,
+   RuVector index, checkpoint, benchmark, and descendant artifact.
+5. Rotate credentials if a provider, cache, or secret may be exposed.
+6. Have the custodian and legal owner choose one disposition: proven
+   non-impact, clean rewrite by unexposed contributors, full retraining from the
+   last clean ancestor, or explicit Apache-derived reclassification.
+7. Repeat all affected ADR-348 gates and record the incident and closure
+   receipts.
+
+If prohibited output becomes a label or tuning signal, all descendant weights
+are affected. Code deletion alone cannot repair model lineage; retraining from
+an approved clean initialization is required.
+
+## 17. Requirement-mapped acceptance checklist
+
+| Check | ADR-348 requirements | Gate | Acceptance condition |
+|---|---|---|---|
+| CR-01 source allowlist | RF-001, RF-002 | G0 | 100% of specification sources frozen, hashed, licensed/termed, and approved |
+| CR-02 contributor exposure | RF-001, RF-002 | G0 | 100% of contributors have current intake and signed attestation; every disclosure has a disposition |
+| CR-03 prohibited-artifact scan | RF-001 | G0 | Zero unresolved prohibited artifacts or outputs across source, history, caches, containers, jobs, data, indexes, and checkpoints |
+| CR-04 similarity review | RF-001, RF-002 | G0 | Every material match adjudicated without exposing implementers to reference fragments |
+| CR-05 dependency/SBOM | RF-002, RF-004 | G1, G2 | Zero unknown or denied dependency licenses; vulnerability policy passes; signed SBOM exists |
+| CR-06 dataset rights | RF-003 | G1 | 100% of bytes map to approved manifests; zero NC, ND, research-only, no-ML, no-production, or unknown terms |
+| CR-07 privacy | RF-003, RF-009 | G1, G5 | Consent/contract, minimization, tenant, retention, deletion, transfer, and sensitive-inference review approved |
+| CR-08 checkpoint lineage | RF-001, RF-002, RF-010 | G1 | Every checkpoint reaches approved random initialization with no prohibited parent or label |
+| CR-09 split isolation | RF-007, RF-008 | G3 | Zero raw/derived overlap across frozen site/subject/session/device/time splits; split-scoped RuVector indexes verified |
+| CR-10 hosted parity | RF-010 | G1, G5 | Local/hosted receipts bind identical governed inputs; provider terms and deletion evidence approved |
+| CR-11 model card | RF-002, RF-007, RF-011 | G3-G5 | Template complete; every value evidence-labelled and reproducible; all blockers explicit |
+| CR-12 trademark and patent | RF-001, RF-011 | G5 | Naming clearance and claim-level freedom-to-operate disposition signed for launch jurisdictions |
+| CR-13 rollback | RF-012 | G5 | Contamination and runtime rollback drills preserve observations and evidence while disabling forecast authority |
+| CR-14 bounded forecast contract | RF-004, RF-005, RF-006 | G2 | Property/fuzz/replay evidence proves finite bounded inputs, abstention, offline execution, immutable observation linkage, and derived-only evidence labels |
+| CR-15 downstream authority | RF-006, RF-009, RF-012 | G4, G5 | No sensing-server hook in the initial PR; any later bridge proves forecast/LLM output cannot mutate observations or acquire prohibited action authority |
+| CR-16 claims and rollout | RF-011, RF-012 | G3-G5 | Every claim has an allowed evidence label and reproducer; mode transitions cannot outrun the highest passed gate |
+
+Any failed or missing check blocks the mapped gate. A maintainer waiver cannot
+convert a prohibited license into permission or an unmeasured capability into a
+measured claim.
+
+## 18. Release record
+
+The legal, data, security, model, and runtime owners sign the same immutable
+release digest. Their approval covers the exact source, data, configuration,
+weights, model card, SBOM, intended use, deployment mode, and jurisdictions.
+Changing any governed input creates a new candidate and invalidates inherited
+approval.
+
+The first production review must also answer one explicit question: does the
+business value of the measured forecast exceed the added privacy, operational,
+compute, and legal burden compared with deterministic baselines? If not, the
+correct outcome is to keep forecasting offline.

 If the ESP32 nodes are provisioned with `--target-ip <AGGREGATOR_HOST>`, that IP must be the machine running `sensing-server`. Only one process can receive UDP `:5005` at a time, so leave the standalone hardware `aggregator` off while the dashboard or Observatory is live.
 
+### 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.

 **Does it actually run, and can a single ESP32 do pose? ([#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.

+`f5ebc5e0142425adae16e9180bf298ef444ea8862ba0d8809c310a39fe45721d`.
+The device partition table was also read before the update and had SHA 256
+`0a8d2f192a8fff209d6c75ab639fcf8aa2f43c64abb732c6e74596fbd6971dca`.
+
+The post update boot log reported firmware 0.8.8, node 7, channel 10, Tier 2,
+an 8 Hz edge DSP cadence, and the preserved sensing server target. The OTA
+status endpoint reported firmware 0.8.8 running from `ota_0`, with `ota_1` as
+the next partition and the correct 1,900,544 byte limit. The sensing server
+health endpoint remained ready with ESP32 input.
+
+## Before and after
+
+The pre update baseline was a 20 second observation on the same attached board.
+The post update observation was a five minute steady state run after boot.
+
+| Observation | Before 0.8.4 | After 0.8.8 |
+|---|---:|---:|
+| Raw callback mean | 39.05 pps | 36.32 pps |
+| Raw callback range | 35 through 42 pps | 24 through 42 pps |
+| Server CSI FPS mean | 46.23 Hz | 48.88 Hz |
+| WebSocket parser errors | 0 | 0 |
+| WebSocket reconnects | 0 | 0 |
+
+Raw callback mean changed by negative 7.0 percent while the server CSI FPS
+estimate changed by positive 5.7 percent. Both remain above the 20 pps
+transport floor. The result is transport neutral rather than an accuracy lift;
+the room and WiFi traffic were not controlled between the two windows.
+
+Firmware 0.8.4 did not expose the edge DSP cadence used by the temporal
+filters. Firmware 0.8.8 held that separately governed clock at exactly 8.0 Hz
+for every controller sample while preserving the higher rate raw network path.
+
+## Five minute physical result
+
+MEASURED on 2026 08 31 after flashing firmware 0.8.8:

+| Device observation | Result |

+
+One ENOMEM backoff occurred during startup and recovered in 210 ms. No memory
+backoff or send failure recurred in the separate five minute steady state
+window. The boot log also reported the documented fail closed OTA behavior:
+the status service was available, but image upload remained rejected because
+this node has no provisioned OTA signing secret.
+
+## Result and limitation
+
+The node 7 timing and transport update passes. Its configuration survived, the
+edge DSP clock remained phase stable at the measured sustainable C6 rate, and
+the live service received fresh node 7 data throughout the run. This does not
+complete the ADR 346 occupancy qualification for node 7 because the room was
+not held empty and the live aggregate did not expose 30 absent edge packets.
+
+The largest uncertainty remains inference accuracy. Timing stability cannot
+prove better vital, motion, room separation, or multi person estimates without
+synchronized held out labels and a controlled empty room sequence.
+
+## Acceptance test
+
+Repeat this five minute procedure after timing, WiFi, filter, or scheduling
+changes. Pass transport only when raw callback yield remains at least 20 pps,
+DSP cadence stays within one hertz of the configured target, the device has
+zero steady state memory backoff, send failure, watchdog, panic, and reboot
+events, the server has zero parse failures and reconnects, and the updated node
+stays fresh. Complete occupancy qualification separately with at least 30
+absent edge packets and zero absent packets carrying a nonzero person count.

+Node 4 reduced the targeted logical contradiction from observed to zero, a 100 percent reduction for this invariant during this run. This is not a person count accuracy result.
+
+The WebSocket run had zero JSON parse errors and one expected client close at completion. The sensing server remained ready with `engine_error_count=0`. A separate 45 second serial observation recorded 120 log lines, 17 CSI callback markers, zero ENOMEM backoffs, and zero other error lines.
+
+The updated OTA status endpoint reports the selected 1,900,544 byte partition rather than the stale 921,600 byte constant. The 1,051,168 byte image therefore fits with 849,376 bytes of partition headroom.
+
+## Remaining qualification
+
+Nodes 3 and 7 still demonstrate the old contradictory behavior and must be upgraded only after their network identity, OTA credential, and rollback path are verified. The current run had no labelled ground truth, so multi person fidelity and adjacent room rejection remain unmeasured.
+
+## Subsequent node 7 status
+
+Later on 2026 08 31, node 7 was separately identified, backed up, upgraded to firmware 0.8.8, and transport qualified for five minutes. That later occupied room run had zero fused presence count contradictions but did not produce the 30 absent edge packets required to supersede the historical control result above. See `docs/validation/2026-08-31-esp32-c6-node7-rate-aware-sensing.md`.
+
+## Acceptance test
+
+Repeat a five minute capture after every firmware change. Pass only when every updated node has at least 30 absent packets, zero packets where `presence=false` and `n_persons>0`, zero parser errors, and a ready sensing server with zero engine errors.

+
+For this C6 record, the S3 result was source and toolchain validation only and
+no S3 runtime claim is made here. The later physical S3 Tier 0 transport run is
+recorded separately in
+`docs/validation/2026-08-31-esp32-s3-rate-aware-transport.md`.
+
+## Measured rate correction
+
+The pre update 20 second C6 baseline delivered a mean 34.05 raw callbacks per
+second, median 34.5, and range 28 through 37. An intermediate 0.8.7 physical
+run requested 10 Hz edge DSP but converged to 8.0 through 8.4 Hz while raw CSI
+remained 30 through 40 packets per second. This proved that C6 Tier 2 compute,
+not the raw transport, was the limiting path.
+
+Firmware 0.8.8 therefore keeps the 50 Hz probe and independent raw network
+path, but sets the C6 Tier 2 DSP clock to its measured sustainable 8 Hz. The
+phase preserving sampler prevents callback jitter from shifting the configured
+clock, and the filter estimator follows processed timestamps rather than raw
+probe intent.
+
+## Five minute physical result
+
+MEASURED on 2026 08 31 after flashing firmware 0.8.8:
+
+| Device observation | Result |

+| Nodes per frame | 0 through 4 |

+
+The boot log emitted one expected iTWT negotiation error because the access
+point rejected the requested target wake time parameters. Firmware immediately
+selected its documented opportunistic CSI fallback. No iTWT or other error
+recurred during the five minute steady state window.
+
+## Result and limitation
+
+ADR 347 timing and transport acceptance passes on the attached C6. Raw
+throughput did not regress relative to the short baseline, the edge clock now
+matches the rate the temporal filters actually receive, and node 4 was never
+stale when present in the live sensing service. The separate occupancy
+qualification recorded 61 absent node 4 packets with zero contradictions for
+the unchanged fail closed invariant. This run did not repeat an empty room
+sequence because the room was occupied during qualification.
+
+The largest remaining uncertainty is inference accuracy. Stable timing removes
+one source of feature distortion but cannot prove better heartbeat, respiration,
+gesture, or multi person classification without synchronized held out labels.
+
+## Acceptance test
+
+Repeat this five minute procedure after any timing, WiFi, filter, or task
+scheduling change. Pass only when raw callback yield remains at least 20 pps,
+DSP cadence remains within one hertz of the configured target, the device has
+zero steady state ENOMEM, send failure, watchdog, panic, and reboot events, the
+server has zero parse failures and reconnects, node 4 stays fresh, and fused
+presence count contradictions remain zero.

+# ESP32 S3 rate aware transport qualification
+
+## Scope
+
+This record qualifies the firmware 0.8.8 raw transport path on one physically
+attached ESP32 S3. The node retained its existing Tier 0 configuration, so this
+run does not qualify the S3 edge DSP rate, temporal filters, heartbeat,
+respiration, gesture, pose, identity, person count, or localization accuracy.
+
+## Hardware and firmware
+
+| Field | Measured value |
+|---|---|
+| Board | ESP32 S3 QFN56 revision 0.2 with 2 MB embedded PSRAM |
+| Logical node | 1 |
+| Firmware before | 0.8.4 |
+| Firmware after | 0.8.8 development build |
+| Edge tier | 0, raw passthrough |
+| App image | 1,127,104 bytes |
+| App SHA 256 | `b531c76900c07d0d6f6e864a5f28afff3e71f124777af97358bb405b34e339a2` |
+| OTA slot size | 2,097,152 bytes |
+| OTA headroom | 970,048 bytes, 46 percent |
+
+The production partition table was read from the device before the update.
+Only the application partition at offset `0x20000` was flashed. WiFi
+credentials, logical node identity, channel, sensing server target, bootloader,
+partition table, OTA metadata, and NVS were preserved. A private recovery copy
+of the prior 2 MB application partition was saved outside the repository. Its
+SHA 256 is
+`14e72c060c4f1a465f739949b873f6aade5b8899a8909f6c5bb591ee49837c1b`.
+
+The post update boot log reported firmware 0.8.8, logical node 1, channel 4,
+the preserved UDP target, Tier 0 raw passthrough, and successful CSI streaming.
+The OTA status endpoint reported firmware 0.8.8 running from `ota_0` with the
+correct 2,097,152 byte update limit. The sensing server health endpoint remained
+ready with ESP32 input.
+
+## Software and image gates
+
+| Gate | Result |
+|---|---|
+| Firmware encoding, vitals, occupancy, and mmWave host tests | PASS, 59 assertions |
+| Firmware provisioning Python tests | PASS, 14 tests |
+| ESP32 S3 IDF 5.4 ARM64 clean build | PASS |
+| Image target detection | PASS, ESP32 S3 |
+| Image checksum | PASS |
+| Image validation hash | PASS |
+| Application partition fit | PASS, 46 percent free |
+| Physical flash write verification | PASS |
+| Preserved runtime configuration | PASS |
+
+The build excluded the optional WASM3 source because it was not present in the
+firmware checkout. The boot log therefore reported WASM Tier 3 disabled. That
+is not a regression introduced by this update and is outside this transport
+qualification.
+
+## Before and after comparison
+
+The pre update baseline was a 20 second serial and WebSocket capture on firmware
+0.8.4. The post update stability observation was 300 seconds on firmware 0.8.8.
+
+| Observation | Before 0.8.4 | After 0.8.8 | Change |
+|---|---:|---:|---:|
+| Raw CSI yield mean | 27.80 pps | 28.03 pps | plus 0.83 percent |
+| Server CSI FPS mean | 39.58 | 39.13 | minus 1.15 percent |
+| Node frame coverage | 100 percent | 100 percent | unchanged |
+| Maximum node staleness | 1,571 ms | 1,565 ms | minus 0.38 percent |
+| Maximum WebSocket frame gap | 111 ms | 112 ms | plus 0.90 percent |
+| Device or parser errors | 0 | 0 | unchanged |
+
+These small movements are operationally neutral and within uncontrolled room
+and WiFi variation. Firmware 0.8.8 did not regress the raw transport. Because
+Tier 0 bypasses the DSP task, this run provides no evidence that temporal
+features or inference accuracy improved.
+
+## Five minute physical result

+| WebSocket errors | 0 |
+| Early closes | 0 |
+| Maximum node staleness | 1,565 ms |
+| Maximum WebSocket frame gap | 112 ms |
+
+## Result and limitation
+
+The ESP32 S3 raw transport acceptance passes. Firmware 0.8.8 booted from the
+existing slot, retained the installation configuration, sustained the prior raw
+CSI delivery rate, and completed the burn with zero transport or runtime
+errors. The result extends ADR 347 physical coverage to the S3 transport path.
+
+The largest remaining uncertainty is S3 Tier 2 behavior and inference accuracy.
+The log line reporting the configured 20 Hz DSP cadence is not proof that DSP
+ran because the preserved Tier 0 setting explicitly disables the DSP task. A
+separate, rollback protected Tier 2 qualification with synchronized held out
+labels is required before making heartbeat, respiration, motion, or accuracy
+claims.
+
+## Acceptance test
+
+Repeat this five minute procedure after any S3 timing, WiFi, transport, or task
+scheduling change. Pass only when raw callback yield remains at least 20 pps,
+node frame coverage remains at least 99 percent, and the device and server have
+zero send failures, offline frames, parser errors, WebSocket errors, watchdogs,
+panics, and unexpected resets. Qualify Tier 2 separately and require its
+measured DSP cadence to stay within one hertz of the configured target.

+# RuForecast requirement to evidence matrix
+
+## Authority and current state
+
+This matrix operationalizes ADR-348 and its ADR-349/350 children without
+changing them. The ADRs own the requirements and gates. Rust tests, immutable
+reports, signed receipts, and explicit human approvals supply evidence. A
+checked box or green build is not permission to deploy, publish a checkpoint,
+upload customer-derived data, or advance the rollout mode.
+
+Current state: all release and operational gates are open. No benchmark result,
+trained checkpoint, external training receipt, or production authority is
+recorded by this document.
+
+## Focused verification commands
+
+The feature-off contract remains on the workspace Rust 1.89 line:
+
+```bash
+cd v2
+cargo +1.89.0 test --locked -p ruview-forecast-core --no-default-features --lib --tests
+cargo +1.89.0 test --locked -p ruview-forecast-model --no-default-features --lib --tests
+cargo +1.89.0 check --locked -p ruview-forecast-model -p ruview-forecast-train --no-default-features --all-targets
+cargo +1.89.0 test --locked -p ruview-forecast-model --no-default-features --features ruvector --lib --tests
+cargo +1.89.0 clippy --locked -p ruview-forecast-core -p ruview-forecast-model -p ruview-forecast-train --no-default-features --all-targets -- -D warnings
+cargo +1.89.0 clippy --locked -p ruview-forecast-model --no-default-features --features ruvector --all-targets -- -D warnings
+```
+
+Burn 0.21 CPU activation uses the explicitly separate Rust 1.92 line:
+
+```bash
+cd v2
+cargo +1.92.0 test --locked -p ruview-forecast-model --no-default-features --features cpu --lib --tests
+cargo +1.92.0 test --locked -p ruview-forecast-train --no-default-features --features cpu,cli --lib --bins
+cargo +1.92.0 test --locked -p ruview-forecast-train --no-default-features --features cpu --test local_jsonl_smoke -- --exact local_hash_addressed_jsonl_executes_one_real_optimizer_step
+cargo +1.92.0 test --locked -p ruview-forecast-train --no-default-features --features cpu,cli --test cli_smoke -- --exact cli_smoke_trains_and_writes_the_complete_candidate_set
+cargo +1.92.0 test --locked -p ruview-forecast-train --no-default-features --features cpu,cli,server,fal-client --lib --bins
+cargo +1.92.0 clippy --locked -p ruview-forecast-model --no-default-features --features cpu --all-targets -- -D warnings
+cargo +1.92.0 clippy --locked -p ruview-forecast-train --no-default-features --features cpu,cli,server,fal-client --all-targets -- -D warnings
+```
+
+The CUDA line is compile-only. It proves that the explicitly gated types build
+on Rust 1.92; it is not a GPU execution, training, latency, or compatibility
+claim:
+
+```bash
+cd v2
+cargo +1.92.0 check --locked -p ruview-forecast-model --no-default-features --features cuda --lib
+cargo +1.92.0 check --locked -p ruview-forecast-train --no-default-features --features cuda,cli,server --lib --bins
+```
+
+The hosted boundary stays backend-free and is exercised on Rust 1.89 with no
+provider credential. Tests must use local mocks; compiling these features does
+not authorize network use or a hosted training run:
+
+```bash
+cd v2
+cargo +1.89.0 tree --locked -e normal,build -p ruview-forecast-train --no-default-features --features cli,server,fal-client > forecast-hosted-feature-tree.txt
+! grep -Eiq '(^|[[:space:]])(burn|cubecl)(-|[[:space:]])' forecast-hosted-feature-tree.txt
+FAL_KEY='' cargo +1.89.0 test --locked -p ruview-forecast-train --no-default-features --features cli,server,fal-client --lib --bins --tests
+FAL_KEY='' cargo +1.89.0 test --locked -p ruview-forecast-train --no-default-features --features cli,server,fal-client privacy_external_dataset_payload_is_denied
+FAL_KEY='' cargo +1.89.0 clippy --locked -p ruview-forecast-train --no-default-features --features cli,server,fal-client --all-targets -- -D warnings
+```
+
+The broader repository gate remains:
+
+```bash
+cd v2
+cargo +1.89.0 test --locked --workspace --no-default-features
+cargo +1.89.0 bench --locked --workspace --no-default-features --no-run
+```
+
+No CUDA runtime result is implied by these commands. CUDA execution needs a
+separately identified GPU, driver, toolkit, source commit, container digest,
+and signed training or inference receipt.
+
+The repository-wide security workflow separately hard-gates the checked-in
+lockfile with `cargo audit --file v2/Cargo.lock --json`. The forecast workflow
+also runs both modes of `scripts/csi-data-policy-check.sh`, rejects forbidden
+clean-room source/import names and model blobs, checks the hosted DTO field
+surface, and blocks common literal private-key, FAL-key, JWT, cloud-key and
+presigned-URL patterns. These focused checks do not close dependency-license or
+complete secret-scanning evidence: the repository has no committed
+`v2/deny.toml`, inherited advisory/yanked-version debt needs an
+owner/date/expiry baseline, and the existing general secret scanners are
+non-blocking. Until dedicated retained reports exist, those parts of G0, G1,
+and G5 remain open.
+
+### Supply-chain and secret release prerequisites
+
+| Check | Reproducer | Present authority |
+|---|---|---|
+| Advisory database | `cargo audit --file v2/Cargo.lock --json` | Existing blocking workflow; report retained |
+| Advisory warnings | `cargo audit --file v2/Cargo.lock --deny warnings` | Not green by assertion; inherited warning debt needs an expiring reviewed baseline |
+| Rust sources/licenses/bans | `cargo deny --manifest-path v2/Cargo.toml --config v2/deny.toml check advisories bans licenses sources` | Blocked until a reviewed `v2/deny.toml` is committed and CI pins `cargo-deny` |
+| Forecast-path secrets | `gitleaks detect --no-banner --redact --source .` | Focused CI blocks common literal patterns; the broader GitLeaks job/report is still non-blocking |
+| Tracked sensing data | `bash scripts/csi-data-policy-check.sh --self-test && bash scripts/csi-data-policy-check.sh --tracked` | Blocking in the focused hosted-boundary job |
+
+`cargo vet check` becomes a release prerequisite only if the project commits a
+vet policy and review process; listing it without that policy would be a false
+supply-chain claim.
+
+### Existing baseline debt and scope
+
+- [`../benchmarks/physics-pose-refinement.md`](../benchmarks/physics-pose-refinement.md)
+  records unrelated workspace rustfmt/warning debt, an incomplete full-workspace
+  test run on that authoring host, existing RustSec debt, and yanked
+  `spin 0.9.8` in the optional Burn graph. Forecast CI therefore uses focused
+  warnings-denied gates and does not describe the whole workspace as green.
+- [`.github/workflows/bench-regression.yml`](../../.github/workflows/bench-regression.yml)
+  records an upstream stable-Rust failure in optional `ruvector-crv`; the
+  focused forecast benchmarks neither enable nor inherit a CRV claim.
+- The current ADR corpus contains pre-existing duplicate ADR-263 and ADR-264
+  numbers. The focused contract rejects a duplicate ADR-348, ADR-349 or ADR-350
+  without falsely asserting that the historic corpus already passes a global
+  uniqueness lint.
+- Shared GitHub-hosted timing is noisy by repository policy. Only benchmark
+  compilation gates the PR; timing logs are informational until repeated on a
+  named, controlled host.

+## Firmware 0.8.8 in plain language
+
+Release 0.8.8 makes the sensing stream more internally consistent and easier
+to diagnose:
+
+1. An empty-room decision can no longer carry a nonzero person count. Older
+   firmware could expose those two contradictory values at the same time.
+2. ESP32-C6 signal processing now uses a stable 8 Hz clock while raw CSI keeps
+   streaming at the faster radio-dependent rate. This prevents temporal
+   filters from silently using the wrong time scale.
+3. The one-second diagnostic reports both raw callback yield and the DSP rate,
+   making slow or overloaded nodes visible.
+4. OTA reports the application slot selected by the board instead of assuming
+   a fixed 900 KB limit.
+
+Two ESP32-C6 boards and one ESP32-S3 completed five-minute physical transport
+runs. The updated nodes had zero steady-state send failures, parser failures,
+watchdogs, panics, or reboots. These results prove timing and transport
+stability, not better heartbeat, pose, identity, or person-count accuracy.
+See the [0.8.8 release notes](../../docs/releases/v0.8.8-esp32.md) and
+[ADR 347](../../docs/adr/ADR-347-rate-aware-esp32-temporal-sensing.md) for the
+measured evidence and limitations.

 ## Quick Start
 
 For users who want to get running fast. Detailed explanations follow in later sections.
 
-### 0. Pre-built binaries (v0.6.5 — skip the build step)
+### 0. Download the 0.8.8 release
 
-Pre-built binaries are in `firmware/esp32-csi-node/release_bins/` (version: see `release_bins/version.txt`).
-Flash them directly:
+Use the versioned source tag and binaries on the
+[v0.8.8 ESP32 release page](https://github.com/ruvnet/RuView/releases/tag/v0.8.8-esp32).
+Choose the package that names both your chip and flash size:
+
+| Package | Use it for |
+|---------|------------|
+| `esp32-csi-node-v0.8.8-s3-8mb-flash-bundle.zip` | Fresh ESP32-S3 installation with 8 MB flash |
+| `esp32-csi-node-v0.8.8-s3-4mb-flash-bundle.zip` | Fresh ESP32-S3 installation with 4 MB flash |
+| `esp32-csi-node-v0.8.8-c6-4mb-flash-bundle.zip` | Fresh ESP32-C6 installation using the supported 4 MB layout |
+
+Each bundle contains the matching bootloader, partition table, OTA metadata,
+application, checksums, and a short flashing guide. Never flash an S3 bundle
+onto a C6, or a C6 bundle onto an S3.
+
+Example for an 8 MB ESP32-S3 after extracting its bundle:
 
 ```bash
 python -m esptool --chip esp32s3 --port COM7 --baud 460800 \
   write_flash --flash_mode dio --flash_size 8MB \
-  0x0     firmware/esp32-csi-node/release_bins/bootloader.bin \
-  0x8000  firmware/esp32-csi-node/release_bins/partition-table.bin \
-  0xf000  firmware/esp32-csi-node/release_bins/ota_data_initial.bin \
-  0x20000 firmware/esp32-csi-node/release_bins/esp32-csi-node.bin
+  0x0     bootloader.bin \
+  0x8000  partition-table.bin \
+  0xf000  ota_data_initial.bin \
+  0x20000 esp32-csi-node.bin
 ```
 
-For 4 MB boards use `release_bins/esp32-csi-node-4mb.bin` and `release_bins/partition-table-4mb.bin`
-with `--flash_size 4MB`.
+For an existing provisioned node, back up its current application and inspect
+`http://DEVICE_IP:8032/ota/status` before choosing an application-only update.
+Writing only offset `0x20000` is safe only when the status endpoint reports
+`running_partition` as `ota_0` and the downloaded image matches the board.
+The full bundles do not include NVS, so the documented four-offset install
+preserves WiFi and node configuration while replacing the boot and application
+images.

 > **⚠️ Thermal warning — compact boards (ESP32-S3-Zero, SuperMini, other coin-sized clones):** This firmware runs the WiFi radio with modem sleep disabled (`WIFI_PS_NONE`, required for continuous CSI capture) plus a full edge-processing DSP pipeline on Core 1 (`edge_tier=2`) plus, on ADR-183 builds, a continuous 40 Hz onboard LED driver. That's sustained high current draw with no duty-cycling. Full-size dev boards (DevKitC-1, XIAO) have more copper pour and thermal mass around the regulator and tolerate this fine. Coin-sized clones with minimal PCB area and budget regulators may run hot to the touch during normal operation, and in at least one field report, boards that ran hot during a session failed to power on afterward (regulator damage suspected — see issue tracker). Give these boards airflow, don't stack or enclose them, and check them by touch during the first several minutes of a new deployment. If a board is uncomfortably hot (not just warm), power it down and let it cool before continuing.

+# 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.

+
+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

+# 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.
