I don't think so. id has p.Id() as base

yes exactly, the base should be Pgid(p.Id())

currently, it is Pgid(0) regardless of the rootPageId we starting from this specific func call

please correct me if i misunderstanding :)

The change isn't correct. Let's work with an example,

Assuming p.Id() == 100, and overflow == 3, then we need to iterate pages: 100, 101, 102.

ahhhh i got it now, p.Overflow() contains count, not the pageIds 👍🏽

sorry my bad 👍🏽

if _, ok := reachable[id]; ok {
ch <- fmt.Errorf("page %d: multiple references (stack: %v)", int(id), stack)
