reset

pub fn reset(n: *PolyNode) void

• Clears intrusive link pointers (prev, next to null). Intrusive means the list pointers live inside your struct, not in a separate list node.

---

is_linked

pub fn is_linked(n: *PolyNode) bool

• Returns true if node is currently linked into a list.

One place, one state — read-only ops

These operations never move a handle:

• tag checks
• typed casts
• @fieldParentPtr recovery

Read-only inspections of an existing node.
