Replaced with a hand-rolled branch-free `constant_time_tag_eq` (XOR-accumulate every byte difference into a single `u8`, no early exit, `#[inline(never)]` + `core::hint::black_box` to stop the optimizer reintroducing a short-circuit or a non-constant-time `memcmp`). **No new dependency** - ADR-157 had deferred this only to avoid adding the `subtle` crate; a fixed 8-byte compare needs none.

The next opportunity is larger: define a common specification for multimodal ambient sensing across RF, ultrasonic, subsonic, infrared, radar, and future quantum sensors. + +Existing standards are valuable but fragmented. + +IEEE 802.11bf 2025 standardizes WLAN sensing at the WiFi MAC and PHY layers and was published on September 26, 2025.

Problem Statement + +Modern sensing systems are locked into modality specific silos: CSI systems produce channel matrices; radar produces range Doppler bins; UWB produces range and time of flight; Bluetooth Channel Sounding produces phase and timing primitives; infrared produces thermal arrays; ultrasonic produces acoustic echoes; subsonic produces structural vibration signatures; quantum sensors produce magnetic, inertial, or optical field traces. + +Each has different sampling, calibration, confidence, privacy, and provenance semantics. This prevents reliable fusion and makes governance weak because raw sensing, derived sensing, biometric inference, and anonymous occupancy are often mixed without explicit boundaries. + +## 5. Goals + +1. Define a common multimodal sensing event format. +2. Define a field tensor format spanning time, frequency, phase, amplitude, range, velocity, angle, temperature, vibration, and uncertainty. +3. Define a modality registry for RF, acoustic, infrared, radar, and quantum sensing. +4. Define privacy classes for raw waveforms, derived features, occupancy, anonymized aggregate state, and biometric inference. +5. Define calibration receipts and provenance hashes. +6. Define fusion rules for multimodal inference. +7. Provide a Rust reference implementation. +8. Provide benchmark tasks for camera free room intelligence. +9. Make RuView one adapter inside a larger open sensing architecture. + +## 6. Non Goals + +1. Do not define a new wireless PHY. +2. Do not replace IEEE 802.11bf. +3. Do not replace Bluetooth Channel Sounding. +4. Do not replace UWB secure ranging. +5. Do not define medical diagnosis. +6. Do not transmit speech, images, or raw biometric identity by default. +7.

Inference Semantics + +Every inference must include: label, confidence, supporting events, contradicting events, privacy class, calibration id, model id, expiry time. + +## 25. Consequences + +Positive: RuView becomes part of a larger sensing ecosystem; the spec creates a standards-style wedge without waiting for silicon vendors; multimodal fusion becomes portable; privacy and provenance become differentiators; enterprise deployment becomes easier to justify; benchmark receipts reduce skepticism. + +Negative: broad scope can dilute execution; hardware variability will be painful; calibration is the hardest practical problem; some will claim existing standards already solve parts of this; medical and biometric use cases require careful governance. + +Mitigation: keep v0.1 narrow; ship real adapters; publish benchmark receipts; do not claim medical diagnosis; position RuField above existing standards. + +## 26. Implementation Plan + +Phase 1 spec skeleton; Phase 2 Rust core; Phase 3 adapters; Phase 4 fusion graph; Phase 5 dashboard; Phase 6 benchmark. + +## 27. Acceptance Criteria + +v0.1 is accepted when: + +1. Three modalities stream into one event graph. +2. Every event has a privacy class. +3. Every event has a provenance receipt. +4. Fusion produces at least five room state inferences. +5. p95 event pipeline latency is below 100 ms. +6. Benchmark runner produces deterministic reports. +7. Raw waveform storage is disabled by default. +8. P4 inference requires consent policy approval. +9. Dashboard shows live camera free room intelligence. +10. Spec is readable enough for external implementers. + +## 28. Reference Repository Structure + +Crates under `v2/crates/rufield-*` (workspace members), spec under `docs/rufield/`, benches under `rufield-bench`. + +## 29. Open Questions + +1.
