REPL.TOKENkevy extension: mint a read-your-writes token — per-shard [generation, offset] pairs (a primary reports its live feed tail; a replica its applied positions).
| Syntax | REPL.TOKEN |
| Group | replication |
| Arity | 1 |
| Since | 3.0.0 |
| Flags | readonly, extension |
| Complexity | O(S) — one (generation, offset) pair per shard |
| Redis compatibility | kevy-only: the read-your-writes token; the nearest Redis concept is master_repl_offset, which is not a resumable per-shard cursor |
