The operational situation that made the project necessary.
The context and the problem are shown together so the reason for the build is immediately clear.
Unit availability and customer terms can change while multiple operators act concurrently.
Problem
Treating reservation as one database insert creates race conditions and inconsistent downstream states.
How the product and system response were structured.
The product experience and the technical response are treated as one connected delivery.
Row-lock the unit, validate state, branch through explicit transitions, snapshot project/unit/customer/payment terms, and let downstream financial and notification workflows consume the same accepted state.
