Protected Campaign Terms After First Use

Context

Retained uses need stable terms, while staff still need the explicitly permitted operational changes after launch.

Decision

First redemption protects designated economic fields while leaving names, dates, limits and audience-combination choice editable.

Alternatives Considered

Permit unrestricted changes after redemption. Later campaign settings would no longer describe the terms under which buyers received benefits.

Consequences

A database check protects economic terms even when an edit races first use. A replacement campaign starts as a distinct unlocked draft with no inherited codes or usage.
