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 pressurized pipe leaks inside walls by fusing two independent signatures: the vibro-acoustic hiss of escaping water and the slowly growing wet-zone dielectric anomaly around the leak.
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 Frontier scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Turbulent outflow at a leak orifice makes the pipe and surrounding wall vibrate at 5-40 Hz (within CSI micro-Doppler band), phase-modulating paths that graze the pipe run; simultaneously the escaping water raises eps_r locally, drifting the delay of paths through that wall section. The AND of a persistent narrowband vibration line plus a co-located slow dielectric drift is nearly unique to a leak.
02 Shared processing path
Stage 2 micro-Doppler extracts persistent 5-40 Hz spectral lines anchored to specific CIR taps -> Stage 1 sparse recovery localizes which delay bin (hence which wall segment) vibrates -> Stage 5 NeRF eps_r map confirms co-located moisture growth -> Stage 6 CUSUM issues alarm on joint evidence; Stage 3 baseline rejects HVAC/appliance vibration learned as normal.
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: mock stud wall with PEX/copper loop and a needle valve leak (0.1-2 L/h), hydrophone + moisture probe ground truth; measure detection latency vs leak rate and false-alarm rate against washing machine/HVAC running.
04 Commercial hypothesis
'A $100 leak detector for every wall, no plumbing work' — for insurers offering premium discounts and smart-building operators cutting water-damage claims (the #1 non-cat property loss).
