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: Long-horizon monitoring of the building shell itself — detecting roof sag under snow load, wall/foundation settling, and moisture ingress into structure or bedding that breeds pathogens and rots timber.
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
Structural movement changes fixed-multipath delays (the geometry literally shifts), and water intrusion into walls/roofing raises local eps_r toward ~80 while metal fatigue/loosening alters strong-scatterer returns — the same reflection-geometry drift already controlled over the proven 119-day run.
02 Shared processing path
CIR sparse recovery of stable structural multipath -> track per-path delay/amplitude drift with compartment Kalman -> CUSUM over days/weeks for slow settling or snow-load sag -> RFF/NeRF eps_r map to localize a wet ingress patch
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
Directly extends the demonstrated 119-day drift-control result; own-hardware winter deployment vs laser roof-deflection measurement and moisture-meter wall probes.
04 Commercial hypothesis
'ShellWatch' — snow-load collapse and moisture-rot early warning for barn/silo owners and their insurers; one prevented roof failure justifies the fleet.
