Definition
Locked as a sub-element under [Operator Throughput]. Full definition lives in the canon entry for [Operator Throughput]; this candidate-history record holds the naming trail only.
Explanation
See [Operator Throughput] and [The Operator’s Constraint] for the governing family. [Throughput-Floor Effect] names the minimum-output condition inside that framework — the floor below which throughput cannot fall without the constraint itself being violated, not a freestanding mechanism with its own independent definition. It sits alongside [Throughput Expansion] as one of the two locked sub-elements under the parent term.
