The evidence is proven or strong, but this capability still needs a capability-specific ESP32 or Rust runtime adapter.
Intended capability
Validate this target only after a capability-specific adapter and ground-truth study exist: Detects the restlessness, repositioning and contraction rhythm that precede birth, alerting the farmer in the critical window to reduce stillbirth and dystocia losses.
This describes the intended outcome. Readiness is needs edge adapter, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording
A related Agriculture scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Pre-parturition behavior produces a distinctive escalating pattern: increased low-frequency locomotion micro-Doppler, frequent lying-standing posture transitions (large RTI silhouette changes), and rhythmic abdominal contractions in a narrow sub-Hz band that differ from normal breathing.
02 Shared processing path
Doppler activity-rate + RTI posture-transition counting -> feature fusion into adaptive PCA+MVE manifold trained on 'normal night' baseline -> deviation spike triggers alert; axis discovery (poke-and-observe) used to sharpen the contraction-rhythm axis from labeled prior births
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
03 Validation plan
Own-hardware in maternity pens with camera + birth-time ground truth across a calving/farrowing season; leverage WiMANS multi-subject activity separation and fall AUC 0.8 posture-change results as priors.
04 Commercial hypothesis
'BirthWatch' — 3am calving alarm to a phone for dairy/swine operations; every saved calf/litter pays for the hardware many times over.
