Actionable review priorities

Requirement: Actionable review priorities

The strongest source-backed review priorities are to correct the unconditional restoration of exist, align deletion feedback with the confirmation branch, review boundary fetches for t_price, and verify customer insertion error handling. Conditional reviews should cover child-before-parent deletion ordering, transaction and SQL-status handling, missing stock-row behavior, invalid-customer feedback, display syntax compatibility, database endpoint and credential conflicts, report interruption detection, and compiled-form availability.
