Detailed Description

Finite capacity regions as linear admission constraints on the fluid state.

EVERY FORM THE REGION CAN TAKE IS ONE FAMILY. A region carries a global job cap, per-class caps, a memory budget with per-class sizes, and an optional linear pair (A,b); all four are the same object once written against the state, Arow x <= b with Arow the per-class weight on the region's coordinates. Collapsing them here means the solver carries one mechanism rather than four.

ONLY WAITQ IS A CONSTRAINT ON THIS DRIFT. Under a waiting queue a blocked job waits outside the region and is admitted later, so the population is conserved and only the admission FLOW is throttled. DROP destroys the job, BAS/BBS/RSRD hold a server upstream, and the retrial rules move it to an orbit: each changes the event set itself, so each needs a different drift rather than a constraint on this one.
