feat(ruview-unified): Unified RF spatial world model — ADR-273..282: native frame contract, encoder, Gaussian memory, synthetic worlds, programmable perception

[ruvnet]

Summary

Implements the unified RF spatial world model (ADR-273): one shared representation where WiFi CSI, cellular SRS, FMCW radar, UWB CIR, BLE Channel Sounding, geometry, semantics, uncertainty, and time all update the same persistent scene memory — instead of another isolated RF classifier. Ten ADRs (273–282) plus a new pure-Rust v2 workspace crate ruview-unified, delivered in three commits.

Commit 1 — P1 pillars (ADR-273..278)

• Universal RF encoder + adapter registry (ADR-274): canonical RfTensor; fail-closed AdapterRegistry (802.11 CSI via wifi-densepose-core::CsiFrame, FMCW cubes, UWB CIR, 5G SRS); tokenizer with measured hardware invariance (window-median scaling + CFO alignment); fusion contract z = Encoder(tokens) ⊙ σ(AgeEncoder(age)) + GeometryEncoder(pose); masked-reconstruction pretraining with a hand-derived backward pass verified against central finite differences (174 params, max rel err 1.31e-5); scalar adapters under a 1 % budget (129/268/387/2 vs 40,856 backbone).
• RF-aware Gaussian spatial memory (ADR-275): anisotropic primitives w/ per-band×angle reflectivity; confidence-weighted fusion, decay, spatial-hash/semantic queries; channel gain as a query (closed-form erf Beer–Lambert; empty map ⇒ exact Friis <1e-15); inverse updates learning an unseen 6.1 dB obstruction to <0.5 dB in 20 observations; task-gated scene graph.
• Physics-guided synthetic RF worlds (ADR-276): Allen–Berkley image method (order ≤2), Fresnel materials, emergent Doppler vs analytic phase rate; reciprocity <1e-12; per-seed byte determinism; physics + hardware-nuisance randomization.
• Edge sensing control plane (ADR-277): 802.11bf/ETSI-ISAC zones/purposes, fail-closed auth, double-gated identity; BoundedEvent the only exportable type — raw RF export unrepresentable.
• Radar inverse rendering (ADR-278): ADR-only gated RISE → DiffRadar → GeRaF reproduction program.

Commit 2 — native contract + programmable perception (ADR-279..282)

• RfFrameV2 (ADR-279): the architectural correction — canonical tensor demoted to a derived view; authoritative record preserves native complex IQ (proven byte-untouched), validity masks, declared PhaseState, poses, and construction-enforced provenance: Synthetic ⇒ L0, Measured ⇒ ≥ L1 (the L0–L5 evidence ladder is a type). SplitManifest certifies disjointness across all seven leakage dimensions incl. session.
• Active sensing control plane (ADR-280): SensingTask admission (raw export refused; identity needs consent); age-of-information planner with measured 95 % traffic reduction; fail-closed coherent-aperture fusion; policy-authorized RIS actuation receipts; purpose-scoped TaskSufficientRepresentation leakage validation.
• BLE Channel Sounding (ADR-281): phase-slope vs RTT as separate cross-validated evidence — exact synthetic recovery, relay-style divergence flagged not averaged. Delay-Doppler-native FieldAxis + delay_doppler_map. IEEE P3162 import profile.
• Factorized pose (ADR-281, RePos): relative skeleton on the content rep, root on the geometry-conditioned rep, calibrated uncertainties. Room-shortcut leakage experiment: held-out MPJPE 0.0003 m vs 0.2534 m monolithic. <2 % structured budget.
• Ecosystem positioning (ADR-282): RuView = edge RF perception runtime under RuField/RuVector/MetaHarness; evidence-ladder policy.

Commit 3 — update-loop completion, optimization, boundary hardening

• ADR-275 update loop closed: merge_overlapping (mutual-Mahalanobis + semantic dedup) and lifetime-aware decay (τ_eff = τ·(1+ln(1+lifetime/τ)) — confirmed structures outlive transients).
• Separable delay-Doppler: O(B²S+S²B) vs O(B²S²), equivalence-proven to <1e-10, measured 8.3× faster (520 µs vs 4.34 ms).
• Security property tests (tests/security_boundaries.rs, 8 proptest properties over NaN/±inf inputs) — found & fixed three input-controlled defects: BLE-CS unwrap infinite loop on non-finite phase + ~1e299-iteration loop on finite-huge phase (→ O(1) modular unwrap + plausibility bound), and a subnormal Gaussian scale → NaN density (→ physical σ/occupancy bounds). Proven: constructors never panic, policy fail-closed, raw export unreachable, fusion rejects non-finite sync, occupancy reps never retain identity.

Measured results (all SYNTHETIC / L0 — honest labeling is structural)

Gate	Result
Presence F1, held-out rooms / chipset	1.0000 / 1.0000
Known→unknown degradation	0.0000 (<0.20)
Held-out ECE	0.0122
p95 tokenize+encode latency	2.0 ms debug / 105 µs release (<50 ms)
Pose leakage (held-out MPJPE)	factorized 0.0003 m vs 0.2534 m monolithic
AoI planner traffic reduction	95 % vs uniform
BLE CS ranging	exact recovery; relay divergence flagged

Benchmarks + optimization (criterion, release): channel_gain 139→27 µs; observe_link 305→74 µs; delay-Doppler 4.34 ms→520 µs (8.3×); DFT plan 4.9×; to_canonical 38 µs, ble_cs_range 481 ns, AoI planner 647 ns, coherent fusion 1.5 µs, factorized pose 521 ns. Hash/linear crossover (~4k Gaussians) and one discarded-as-worse corridor attempt reported honestly (ADR-275 §6).

Validation

• cargo test -p ruview-unified — 98 tests (87 lib + 3 acceptance + 8 security), 0 failed; crate clippy-clean
• cargo test --workspace --no-default-features --exclude wifi-densepose-desktop — green (1805+ observed; desktop/Tauri crate cannot build here: GTK dev headers absent — pre-existing environment limitation, run unexcluded in CI)
• python archive/v1/data/proof/verify.py — VERDICT: PASS
• Docs: CLAUDE.md, README + docs/adr/README.md index, CHANGELOG [Unreleased]; .gitignore excludes proptest regression caches

What this is NOT / what remains (hardware- and data-gated)

• No real-world accuracy claim: every number is generator-produced (L0). P2 = real .csi.jsonl replay + measured-data strict splits (ADR-273 §7) — needs captured data.
• P3 = wire GaussianMap into the live sensing server behind the ADR-277 boundary; P4 = O-RAN SRS xApp (adapter seam ships here) — need the testbeds.
• ADR-278 radar inverse rendering stays a gated research program (needs mmWave hardware + reproduction).
• Witness-bundle regeneration blocked on the desktop crate's GTK headers in this container — flagged for the release owner (CI with GTK regenerates it).

Deep review + hardware-in-the-loop test

Reviewed ruview-unified end to end (adapters/frame contract, RF math/encoder,
Gaussian memory/security boundaries) and tested the WifiCsiAdapter against a
live ESP32-C6 CSI node, not just synthetic data. Full write-up: https://gist.github.com/ruvnet/89795f3c4b8ea166cff5ac35ae4c7651

Fixed in 8ce3bd090 (pushed to this branch):

• pretrain.rs: guaranteed panic on any single-token window (usize::clamp(1, 0)).
• math.rs: resample_complex silently produced NaN when downsampling to 1 sample.
• gaussian/map.rs: merge_overlapping was missing the entity-kind guard insert() enforces — could silently conflate a Room Gaussian with a PersonClass Gaussian.
• adapters.rs: WifiCsiAdapter used the frequency band's fixed constant instead of the real per-frame channel. Confirmed live: a real ESP32-C6 node on channel 4 was misreported as 2437 MHz pre-fix; post-fix it correctly reports 2427 MHz, matching the hardware parser's independently-computed frequency exactly. Added examples/esp32_live_hardware_test.rs as a standing hardware-in-the-loop check (also confirms no panic on real 256-subcarrier HE-SU frames, beyond CANONICAL_BINS=56).
• control.rs: admit_task didn't validate resolution/latency/modalities.
• validate_representation's only test coverage (unit + proptest) hardcoded Presence, leaving the P3/P4/P5 purpose branches unverified — added coverage for all of them.

Also fixed pre-existing issues surfaced while validating (unrelated to this PR's diff): 7 clippy warnings in wifi-densepose-core's canonical encode/decode path, a Windows-breaking test in ruview-auth missing #[cfg(unix)], and a port-collision flake in sensing-server's auth_wiring.rs integration test.

All touched crates re-verified post-fix: ruview-unified 99/99 tests (clippy-clean under -D warnings), wifi-densepose-core 37+40, wifi-densepose-hardware 483+1(ignored), ruview-auth builds/tests on Windows, sensing-server auth_wiring 7/7.

A few of the PR's headline "MEASURED" numbers are narrower than they read (detailed in the gist) — worth a look before citing them elsewhere, though none are code bugs: the RePos leakage-resistance test never exercises the actual encoder, the "empty map ⇒ exact Friis" test never invokes the erf path it's named for, and the "6.1 dB obstruction learned in 20 observations" is 20 repeats of one measurement converging a single scalar.
