OPS.5:10 - Rationale

Admission is valuable because it protects the boundary between possible demand and authorized current Work. Combining it with queue design, performed Work, or service assurance would make a locally usable decision depend on much wider results and would hide exactly where permission and evidence are needed.

The four dispositions prevent the false binary “start or lose”. Direct rules remain direct, genuine alternatives can be compared, and residual demand stays available for reconsideration or specialist return. The pattern therefore closes the smallest decision that lets a continuing operation limit starts while leaving unresolved queue, constraint, capacity, interacting-structure, and whole-service questions for their own decisions.
