The abstraction outranks its first application. Aspect-as-subscope only exists because scope-object gave the criterion a first-class home; had scopes shipped as merely renamed parents, aspects would have returned as a bolted-on vote tag, which is the design this edge exists to prevent.
The staircase is load-bearing, not decoration. Without the recompression step, aspect-as-subscope quietly rebuilds the hatch the one-ranking removal welded shut, and the canonical ranking starves while the easy scopes eat the votes. Narrow edge because the staircase is worthless without the sub-scopes it sequences — they need each other, but the guard outranks the door.
An aspect inherits its border rather than contesting it, so membership stays senior: no beauty vote can smuggle anyone past the jedi border. Bookkeeping weight, cast to bind the new items into the component.
Prompt-as-proposal answers the authorship fork in the latest post without pretending the question is neutral. The author gets to ask; the community gets to decide whether to enter, populate, compare, and eventually privilege that scope. Cheap question formation, expensive closure.
