alternatives:
  - option: Keep the price from the earlier assessment
    why_not: The original assessment can outlive the price or audience qualification that produced it.
  - option: Accept recalculated amounts without renewed review
    why_not: The newly charged amount would bypass buyer review.
consequences:
  - Preview stores the detailed assessment used for subsequent comparison.
  - The composer offers no lasting staff-entered price override.

# Placement recomputes the price and refuses a change

## Context

An assessment can age while prices, qualification or offers change.

## Decision

Use newly calculated placement prices and compare their relevant figures with the stored assessment. A difference requires another buyer review before the sale commits.

## Alternatives Considered

Honoring an old assessment can bypass current price eligibility. Silent repricing can charge an amount the buyer did not review.

## Consequences

A changed purchase may need another preview. The composer exposes no staff price override that would survive this recalculation.
