`closed` means the filed components sum to the filed input. `failed` means they do not, by the stated residual.
`insufficient` means the check could not run because figures are missing — never to be read as a pass.

## How the cost figure is built

Apparent loss is water delivered and never billed, so it is valued at the retail rate: revenue, recoverable inside a
budget year without capital work. Real loss is valued at variable production cost, because eliminating a leak saves
treatment and pumping rather than retail price. Where the filed audit carries its own cost of losses — as TWDB's
export does — those figures are used directly and no rate of ours enters the calculation.

Volumes are normalized to million gallons on ingest; the export reports them in the unit each filing states.

Figures are as filed unless stated otherwise. If a number here is wrong it is wrong in the filing or wrong in
our reading of it, and both are worth knowing: ammar@municorn.us
