tracer bullet

• Тип боеприпаса с пиротехническим зарядом, делающим снаряд видимым в полёте, используемый для наблюдения за траекторией и корректировки прицела; также используется метафорически в разработке программного обеспечения для описания быстрого сквозного прототипа, помогающего проверить технический подход.

A type of ammunition with a pyrotechnic charge that makes the projectile visible in flight, used to observe trajectory and adjust aim; also used metaphorically in software development to describe a quick, end-to-end prototype that helps validate a technical approach.
