A frontier proposal with a validation plan, not an implemented detector.
Intended capability
Research whether the field could support this proposed outcome: 3D map of moisture and dry-matter distribution inside a stored-grain bin, pinpointing wet pockets and self-heating spoilage nuclei weeks before mold, mycotoxin or silo fire, plus a live fill-level readout.
This describes the intended outcome. Readiness is research concept, evidence is class C, 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
Grain permittivity rises steeply with moisture (dry grain eps_r ~3-4, wet/spoiling pockets trend toward water's eps_r ~80), and settling/caking changes bulk density. These alter both path delay and reflected amplitude through the bin — a physically visible dielectric contrast, not an inference.
02 Shared processing path
CIR sparse recovery of super-resolved multipath delays through the grain column -> RFF/NeRF field reconstruction of eps_r/sigma voxels -> compartment Kalman + CUSUM tracking of each voxel's eps_r drift over days/weeks to localize a growing wet/hot nucleus
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: ESP32 nodes ringing a test bin filled with grain at controlled moisture gradients, ground-truthed with insertable moisture probes and thermocouples; ESP32-wall dataset to calibrate through-medium CIR delay recovery.
04 Commercial hypothesis
'SiloSight' — insurance-grade spoilage & silo-fire early warning for grain elevators and co-ops; sees inside the pile where thermocouple cables can't.
