Struct FrameInfo 

pub struct FrameInfo {
    pub function_id: Option<u16>,
    pub function_name: String,
    pub blob_hash: Option<[u8; 32]>,
    pub local_ip: usize,
    pub locals: Vec<KindedSlot>,
    pub upvalues: Option<Vec<KindedSlot>>,
    pub args: Vec<KindedSlot>,
}

Information about a single VM call frame, captured at a point in time.

Refcount discipline via KindedSlot. Per ADR-006 §2.7 the locals / upvalues / args vectors hold KindedSlots — the GENERIC_CARRIER vector form. KindedSlot’s explicit Drop and Clone impls dispatch on NativeKind to retire / bump heap refcounts, so Vec<KindedSlot> push / pop / clone preserve the WB2.4 / WB2.5 retain-on-read invariant by construction. The manual Clone / Drop impls calling vw_clone / vw_drop_slice that pre-bulldozer code carried are no longer needed.
