release notes

Automated release from CI pipeline

Changes: research(R6): Fresnel-zone forward model — bedrock physics for CSI sensitivity (#710)

The workspace DSP (vital_signs, multistatic, pose_tracker, tomography) implicitly assumes a forward model that maps scatterer geometry to per-subcarrier phase shifts. Nobody had written it down. This tick makes it explicit.

Closed-form first-Fresnel-zone radius + point-scatterer path-delta + per-subcarrier phase prediction over 802.11n/ac 20 MHz channels (52 subcarriers, 312.5 kHz spacing). Pure NumPy demo + JSON output for downstream consumers.

Headline numbers:

5 m link first-Fresnel radius @ midpoint: 40 cm (2.4 GHz), 27 cm (5 GHz)
Inside zone-1: phase spread <0.5 deg across 52 subcarriers (band-flat)
Outside zone-1: phase spread up to 16 deg (band-dispersed)

This unifies R5 + R6: R5's experimentally measured band-spread top subcarriers is exactly what the Fresnel forward model predicts for zone-1 occupancy.

Closes the loop on three earlier threads:

R7 (mincut adversarial) gets a precise definition of 'physically inconsistent' instead of a learned classifier
R10 (foliage range) needs to retract 100 m sparse estimate to ~70 m to account for Fresnel-zone obstruction
R12 (eigenshift negative result) gets its revision basis: PABS over Fresnel-grounded forward operator

Honest scope: point-scatterer only, first Fresnel only, frequency-flat reflectivity, LOS-only (no multipath). The scalar version is the right first-order approximation; volume-integral / multi-zone / multipath extensions catalogued as R6.1+R6.2 follow-ups.

Coordination: ticks/tick-8.md, no PROGRESS.md edit.
