Project Budget Generator — illustrative example

INPUT
Design $600; implementation $1,200; testing cost not supplied.

RESULT
Known subtotal: $1,800. Flag testing and any contingency as unresolved instead of calling this the complete project budget.

REVIEW
Budgets should separate known prices, estimates and contingency. A total is incomplete when major work packages have no cost assumption.

This is a teaching example, not a live execution record.
