Magic becomes structurally useful when it obeys a stable operating regime: a source, an access rule, a deployment cost, and a social distribution pattern.
If those limits are vague, magic can explain anything and therefore explains nothing. If those limits are explicit, magic starts to reshape settlement, governance, warfare, storage, and hierarchy in predictable ways.
A magic system's scale limit is rarely a neutral technical detail. It decides which institutions can monopolize the capability, which cities can support it, and which frontiers remain outside its reliable reach. This is why the model asks about scope alongside source, access, and cost. Once magical action scales unevenly, hierarchy and geography start changing with it.
The main failure is to define magical effects without defining what reproduces them reliably. A setting says healing, messaging, wards, or force projection are possible, but never names the institutions, reagents, risk ceilings, or training bottlenecks that keep those effects unevenly distributed. The model is strongest when those bottlenecks are explicit enough to shape ordinary life.
Once magic has a stable regime, it stops being an isolated effect and starts rewriting everyday structure. It can change where cities are viable, which elites dominate, how fast messages move, what kinds of wounds remain survivable, and which frontiers become governable at all.
The reusable lesson is that a magic system should not only define effects. It should define institutions, bottlenecks, and scaling limits.
Magic feels consequential when it rewrites communication, defense, extraction, healing, or transport through explicit ceilings and dependencies rather than case-by-case authorial permission. That is also what keeps exceptional acts dramatic, because the reader can tell when a spell is exceeding the normal regime instead of merely replacing ordinary causality.

Continue from this node by program branch and operating scale.
Detail pages now expose the branch and scale of their surrounding graph before showing raw prerequisite and relation shelves, so continuation can stay taxonomy-led instead of adjacency-led.

Start with the operating regime, price the capability through diffusion or monopoly models, compare a regime-rewrite case, then run a capability sanity check.
