release notes

Automated release from CI pipeline

Changes: research(R13): NEGATIVE — contactless BP from CSI is physically inferior to a cuff (#713)

Critical-physics scrutiny of published 'contactless BP from WiFi CSI' claims (Yang 2022, Liu 2021, others). Four physics floors quantified; all four make CSI-based BP provably worse than a 20 dollar arm cuff.

PTT temporal resolution: need 0.5 ms for 1 mmHg precision; ESP32-S3 maxes at 1 ms (1000 Hz CSI) and typical deployment is 10 ms (100 Hz) = 20 mmHg precision floor. Achievable but requires sacrificing every other sensing pipeline.
Spatial separation: carotid-femoral distance 55 cm, Fresnel envelope at 5 m link is 40 cm. Single-link CSI cannot resolve the two sites independently. Multistatic with 4-6 anchors is severely ill-posed (same regime that defeated R12).
Pulse-contour SNR: pulse motion at chest is 0.3 mm; breathing is 8 mm (27x larger). After 4th-order bandpass we get +20 dB HR-band SNR; literature (Mukkamala 2015) says +25 dB minimum for waveform- shape recovery. 5 dB short.
Vs 0 arm cuff: best published CSI BP is +/-10 mmHg with per-subject calibration; arm cuff is +/-2 mmHg uncalibrated. CSI is 5x worse AND requires calibration the user doesn't otherwise need.

Verdict: do not ship BP as a primary RuView feature. The breathing/HR features we already ship work because their motion amplitudes are 30-100x larger than the pulse waveform. Adding BP would force 1 kHz CSI rate (degrading every other pipeline), require per-subject calibration (defeating no-setup story), and ship a feature that's worse than a 20 dollar device the user can buy.

Three niche scenarios remain open:

Single-subject trend monitoring (relative not absolute)
Bed-instrumented controlled-still subject (25+ dB achievable)
Multistatic PWV with 6+ anchors + per-installation calibration

The general 'BP from a 9 dollar ESP32 in the corner' claim does not close.

Composes:

R1 (CRLB) confirms temporal-resolution floor for PTT
R6 (Fresnel) provides the spatial floor that defeats two-site PTT
R5 (saliency) explains why whole-chest observable but 0.3 mm pulse not
R12 = loop's other negative result, same failure pattern
R14's assumption (no BP) is now empirically validated

Two negative results in this loop (R12, R13) prevent the field from biasing toward overclaiming. This is the most valuable kind of tick because it marks BP-from-CSI as off-roadmap with explicit numbers, so future contributors don't waste cycles attempting it.

Coordination: ticks/tick-11.md, no PROGRESS.md edit.
