Five stages from signup to the first invoice. The customer still sees Retry payment; the failure is a backstage dunning-job timeout sitting below the line of visibility.
THE FINDING
Under Hit the limit, the customer row still says Retry payment. The timeout lives on the backstage row, below the line of visibility — a billing job, not a copy problem on the pay modal.
Stages are equal columns. Layers are labeled rows. Everything above the heavy rule is onstage; everything below it is hidden. No arrows: stage order is the sequence, and wait times are cell text.
Upgrade and First invoice restore the walk: tax calc and ledger post below the line, checkout and receipt stay above it. The timeout is the one accent cell the figure exists to show.
