Upgrade seed

"The Forerunners were master shipbuilders, among other things. They were explorers as well, spreading across a galaxy of three million occupied worlds. It was not uncommon for them to find themselves in contact with other species and races with rudimentary ships such as yours. They utilized design seeds to build their own ships from local resources if necessary. But there were many occasions when resources could not support a design, so the Forerunners used whatever local vessels they could obtain and created an upgrade seed - hard light instructions, blueprints, if you will, which bonded to an existing structure, reinforcing the materials, molding them as needed, and upgrading components and systems."

— 343 Guilty Spark explains the upgrade seed to the crew of the Ace of Spades.

An upgrade seed was a type of design seed utilized by the Forerunners to upgrade vessels of other species to have Forerunner technology upgrades within the ship's original framework of operating functional capability.
