or t can be like this

t: ([]isMatched: (1b,1b,0b,0b;1b,1b,0b,0b;0b,0b,1b,1b); index:((0,1,2,3);(1,0,2,3);(0,1,2,3));id: ((`a,`b,`c,`d);(`a,`b,`c,`d);(`a,`b,`c,`d)))

i am missing the `  before the x1,

update originalId:{x1:y x;$[ `=x1;x;.z.s[x1;y]]} [; Id!PrevId] each Id from table`

so basically if prev id is empty then stop iterating. How will that work i assume at each id it only has one map id!prev how will it iterate through to find the ultimate id?
