Retained for transparency, but blocked from execution because the catalog physics review rejected it.
Intended capability
Document why this proposed outcome is blocked by the reviewed physics: Contact-free fill-level monitoring of clean-agent fire suppression cylinders and day-tank diesel through their steel/composite walls, flagging slow leaks or post-discharge partial fills that pressure gauges miss.
This describes the intended outcome. Readiness is physics limit, evidence is class C, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording
A related Datacenter scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
The liquid/gas boundary inside a tank is a dielectric discontinuity (liquid agent/diesel eps_r 2-10+ vs. gas ~1) that shifts the tank's external scattering signature; as level drops, the effective scatterer geometry and near-field multipath around the tank bank change reproducibly.
02 Shared processing path
CIR sparse recovery of tank-bank reflection paths -> axis discovery (teach the level axis by logging signatures during scheduled refills/weigh checks) -> RFF/NeRF local material map around the tank row -> compartment CUSUM for week-scale slow-leak drift.
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: instrument a diesel day tank or water-filled surrogate cylinder, vary fill 0-100% in 10% steps, regress RF signature vs. sight-gauge truth; steel-walled cylinders are the hard case — quantify which tank materials are observable.
04 Commercial hypothesis
Continuous verification that your fire suppression is actually charged — 'the weigh-scale audit, every hour, no crane' — sold to the critical-facilities compliance manager (NFPA weigh-check pain point).
