In the Subrule 2.5.1 Spacecraft Equipment, replace ‘Spacecraft Equipment can be added to a spacecraft, if there is enough room. All SE has a size statistic, which must be a positive integer. A piece of SE can be on a spacecraft if the Remaining Space of that spacecraft is equal to or larger than the size of the equipment.’ with

All SE has a size statistic, which must be a positive integer. By way of a proposal or as described by a rule, if the Remaining Space of a spacecraft is equal to or larger than the size of a piece of SE, that piece of SE may be added to the spacecraft and the size of the SE subtracted from the Remaining Space attribute of the spacecraft.

This is admittedly pretty trivial and maybe unneccessary, but the previous wording wasn’t really explicit enough, and suggested a piece of SE would somehow be breaking the rules if it were on a spacecraft that does not have enough remaining space to fit it on, even though it’s already there and therefore already subtracted. It’s basically just ‘be on’ versus ‘be added to’.
