ZPOPMIN.BELOWkevy extension: pop up to count lowest members with score strictly below the threshold (delayed-job primitive).
| Syntax | ZPOPMIN.BELOW key below [count] |
| Group | zset |
| Arity | -3 |
| Since | 3.0.0 |
| Flags | write, extension |
| Complexity | O(M log N) — take_while stops at the first score at or above the threshold, so it never walks past the due prefix |
| Redis compatibility | kevy-only: a delayed-job primitive (score = due time); no Redis analogue |
