Kernel Hearts’ post-run upgrades come with a capacity label. The official description says run rewards unlock chips and let you equip up to 256KB on the unit. Access to a chip and room in the equipped build are two different conditions.

That gives returning to the laboratory a selection problem as well as a growth problem. A larger unlocked collection can offer more candidates without enlarging the stated equipped ceiling. The listing provides no individual chip sizes, so we cannot calculate a combination or assume that a particular upgrade must displace another.

The useful attraction is a boundary around the loadout you take forward. If you like developing options and then deciding which ones belong together, the 256KB rule tells you what to look for in Kernel Hearts’ chip system. It is a limit on the advertised build, not a specification for your computer.

Sources & context

The listing gives an equipment capacity, not individual chip sizes or an optimal loadout. KB is treated as the game’s advertised build constraint, not a claim about executable memory use.

One mechanic, the decision it creates, and a little dry humor.
