Baseline provision is another name for the floor: whatever is required to remain a viable participant in the first place. Most of it arrives as monthly floor credits for home, food, and mobility. Healthcare, education and formation, legal access, communication, and public safety stay pooled and guaranteed in kind, because one person cannot insure them alone or because they must not vary with where someone lives. Crucially, it is not earned: it is the condition that makes standing materially real rather than symbolic, because telling someone they belong while denying them the means to take part is a hollow belonging.
Above the floor
Above the baseline, three different things move. Resources to do the work, such as an operating room, compute, or a studio, are allocated by what the work requires, the logic of commensurate participation. Contribution income is personal pay, through the four channels. Scarce goods follow their own rules. Keeping them apart is what stops the model from collapsing into either flat equal distribution or allocation by whoever is already richest. See How Abundance Allocates and How Contribution Gets Paid.
