Gravity waste leak comparator

Independent gravity-head fill, backflow and retained-volume comparison with reference geometry and contained water test; sensitivity unknown

Discovered · unresearchedClosure: OpenInventory incomplete

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

Hand shape separate notched gravity water column/overflow and matched collection increments, compare retained volume/head and timed seepage with independent coarse reference marks; no pumped pressure or mass balance claimed
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
