// Slot 1: reads cross-VM share keys written by slot 0 (share_writer.tc).
//
//   RDRALL  — dump all three keys + shareHas("counter")
//   RDRDEL  — delete "counter", expect writer to recreate it next tick
//   RDRINT  — just the int
//   RDRFLT  — just the float
//   RDRSTR  — just the string
//   RDRMISS — read a key that doesn't exist (sanity for "0/0.0/empty" return)
