The failure mode is ordinary. The phone rings during the weeks before a holiday, when a 12-door kitchen has to be done without a full rip-out, nobody answers, and the kitchen sits half-faced because the hinge style was never written down.
Ren answers and writes door count, species, hinge style, and overlay before talking about a clock time. The Door face minutes turns those counts into minutes of face work so the company sees a size, not a vague "can you come look."
Then one company is offered the note. A local installer hangs the faces. Ren does not build new boxes. If the window cannot be met, the caller hears the next real opening, not a promise that keeps the board pretty.
The note is the product. A callback that skips door count, species, hinge style, and overlay creates the second angry call.
