final class CascadedChildren

The rows of one child table as a cascade leaves them.

Following a constraint reads the child rows once and then rewrites some and drops others, and the caller needs both the rows to write back and an account of what happened to them. Keeping the two together is what makes the account impossible to disagree with the rows.
