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: Reads fill levels of water tanks, thermal storage, glycol reservoirs and detects pipe-lagging saturation in plant rooms — no probes, no penetrations, works on sealed and legacy vessels.
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 Buildings scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
The air-water interface inside a tank is a strong dielectric discontinuity (eps_r 1 vs 80): as level changes, reflection/transmission paths through the vessel shift in delay and amplitude, and the water column's bulk absorption scales with fill height. The eps_r field map literally images how much water is where.
02 Shared processing path
CIR sparse recovery of paths transiting the vessel -> RFF/NeRF eps_r reconstruction of the tank voxel column -> axis discovery calibration (one controlled fill/drain cycle teaches the level axis) -> Kalman-tracked level output + CUSUM for slow-leak (unexplained level loss) alarms.
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: 200L plastic tank between ESP32 nodes, stepped fill/drain vs float-gauge ground truth; repeat with steel tank (exploit dome/fitting paths) to bound the metal-vessel case.
04 Commercial hypothesis
For the facilities/plant manager: 'Retrofit-free level sensing on every tank in the mechanical room — and a slow-leak alarm you never had to plumb in.'
