# 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.
